Datang Institute of Technology

Xu Changcun's big shipments have started, especially in terms of snacks.

Because vacuuming improves the shelf life, other Xujia supermarkets in Datang Shidao also began to collect goods one by one.

The production of bicycles is becoming more and more familiar, and the output has increased greatly, and a lot of shares have flowed to economically important cities such as Luoyang and Jinling.

The same is true for briquettes and honeycomb stoves, which started to be exported as a new product.

Of course, Xu Changsheng's recycling system is also in operation.

For example, the previously proposed recycling of cola and herbal tea bottles has worked well.

The gardenia and rose flowers that were recovered later were also recovered a lot. I have to say that the lady of Datang is very talented in planting flowers. I guess this is a racial talent. Because of this, gardenias and roses The sales volume has improved again. After all, they grow well, which is basically equivalent to giving them white flowers to raise. The Xu family can also get the flowers to extract the essence to make soap, which is the best of both worlds.

There is also the recycling of plastic bags.

Xu Changsheng was worried at first that people would litter and cause pollution, but after he introduced the recycling mechanism, it was really not easy to find discarded plastic bags on the road.

There are many poor people in Datang. These plastic bags are money in their eyes. The money thrown on the ground will never be picked up for a long time before being picked up, especially for beggars, who have an extra way to eat.

Every day these tattered beggars would bring some plastic bags to Xu’s supermarket to exchange for money, and they would show gratitude. It would be a great gift to them even if they could buy a cake with the money from selling plastic bags.

In ancient times, there were not a few beggars.

What Xu Changsheng has to do now is to dispose of these recycled plastic bags. If they are allowed to pile up, they will not melt for thousands of years, and it will be a disaster for future generations. While enjoying the convenience brought by plastic bags, then we must Take responsibility for dealing with them.

At the current level, it is out of reach to deal with plastics chemically.

Xu Changsheng thought about it, and it's not impossible to deal with it, and under the current conditions, there is really a good way to deal with these white garbage.

Xu Changsheng looked at the wheat drying on the white road. These wheat can be used to make soft and delicious bread, and his method of dealing with plastic is... mealworms.

Mealworms, also known as mealworms, are miraculous insects that can feed on plastics, degrade these white plastics directly in the body, and assimilate them to form their own tissues.

The remaining part is excreted from the body, and these insect droppings will continue to degrade and can be used directly as fertilizer.

The magic of nature is nothing more than this.

The raw material he is now using to make plastic is pure natural resin, without any additives, which is supposed to degrade better.

This biodegradation method has been used in modern times, providing new thinking for dealing with white plastic waste.

The Tenebrio molitor that grew up eating plastic can also be used to feed chickens. It contains 50% of the protein in the whole body, and feeding chickens is simply a great tonic.

What Xu Changsheng plans is such an effective and high-energy recyclable treatment system.

Now, he had to get the bread out.

He had eaten the scallion pancakes sold in Chang'an, they were so hard, they were not tasty at all.

His bread is different, it is soft and delicious, and it has a lot of flavors. After it is made, there must be a good market.

The key is low cost.

It can be regarded as giving benefits to the people of Datang, so that they can afford to eat and have enough food.

Holding a bucket in his arms, he dug a bucket of wheat on the ground and ran away.

The adults of the Xu family were stunned for a while, but the children's eyes lit up, and they ran after him. Changsheng must make delicious food.

Now each of them still has popcorn in their hands, stuffing it into their mouths as they run.

Now the children in Xujia Village are very happy, they can eat a lot of snacks every day, Xu Changsheng is a little worried, what's wrong with eating all the snacks.

Xu Changsheng took the wheat and ran to the back mountain, where he borrowed a stone mill to grind it into flour.

A group of children surrounded them, licking their little mouths.

Uncle Clan also smiled and helped to grind the noodles, "Changsheng, what are you going to do? Last time you melted your hoe just to make popcorn for a group of children?"

Xu Changsheng was also a little embarrassed. Popcorn cannot be mass-produced, so a group of children can only eat it by themselves, because it takes too much iron to make a popcorn machine, and it is impossible to buy iron in large quantities, and they dare not buy it.

Xu Changsheng said, "This time the people in Tang Dynasty can eat it. It's a good thing, and the price is not high. It can be regarded as improving the living standard of people in Tang Dynasty."

The clan uncle was taken aback for a moment, and his expression became serious. To provide a standard of living for the people of Tang Dynasty?

This is a big deal.

Xu Changsheng was right. The staple food of the Tang Dynasty was wheat, beans, etc., and a large amount of wheat was planted, which means that wheat is a daily necessities, and the price will not be too high, while bread is made of wheat, and the price is not too high. .

His Xujia supermarket sells cheap and delicious bread, isn't it just to improve the level of the people.

The uncle of the family took the noodle grinding seriously.

It didn't take long to grind out a big pot.

Xu Changsheng looked at it, and it was clean and white.

Fortunately, he made the windmill, otherwise he wouldn't need such clean flour.

A few children helped carry the flour and left.

Then there is the face-to-face.

A group of children were asked to wash their hands clean with soap, and each of them shared some flour and started mixing.

You want the bread to be soft and the dough to be firm.

As for the alkali for fermentation, they have used it to make bean curd, so just go and get a little.

A pot of flour was mixed into a pot of dough, Q bomb Q bomb.

Because there is no yeast, the fermentation time is longer.

Xu Changsheng asked a group of children to play and come back in the evening, but none of them left, so they just looked at the pot of dough with longing eyes.

Just wait, anyway, it's sunny outside, and there is an ice basin in the room, so it's cool!

In the evening, I went to milk the milk again, beat a few eggs into it, and added a little sugar.

After fermentation, the dough is twice the size of the original flour, which must be soft enough.

Then make a small dough, roll it into a long flat shape, apply the milk and egg white just now, and knead it well. It will look good in this way.

Then put it on the pan and bake.

Because it was the first time I made it, it was a little burnt.

However, a group of children looked a lot bigger, and the smell of bread made their saliva almost flow out.

Xu Changsheng took a tear and put it in his mouth.

It's full of wheat fragrance and milk fragrance. It's great, and it's so soft.

It’s been a long time since I’ve eaten such delicious and soft food.

A child divided one.

"It's... really delicious."

"How can it be so soft? It's much tastier than the steamed buns I've eaten."

Xu Changsheng smiled, in fact, the steamed buns can also be made very soft, unlike the hard ones made in Tang Dynasty now.

What he is making now uses milk. In fact, it is possible to not use milk, but the fragrance is not so pure, but it doesn't matter. As a cheap product, it doesn't need to be so fine.

Let them eliminate the ones that have added milk.

Moreover, his black-and-white flowers are already fighting with a scalper, and it won't be long before he can breed more small black-and-white flowers.

There are many varieties of black-and-white flowers. Modern black-and-white flowers are hybrids of foreign black-and-white flowers and cattle, and the milk production is not low at all.

Xu Changsheng sent some to his grandfather, who was amazed, "Is it really made of wheat?"

Xu Changsheng nodded, and then stretched out ten little fingers, "How about we sell it at this price?"

The great grandfather was taken aback, "Ten Wen? When did you know how to be sympathetic to others?"

A scallion pancake costs five cents, but the bread has added sugar, and it tastes much better than the scallion pancake. The price is already very close to the people.

Xu Changsheng thought to himself, although a loaf is quite big, it is actually because of the full fermentation. In fact, the flour used is not as much as that of scallion pancakes. If it weren't for the addition of sugar, he wouldn't dare to sell it at this price.

And there is not much sugar added, after the wheat is roasted, it has some sweetness.

Furthermore, when his beets are planted, if he produces sugar himself, the cost of sugar will be even lower.

The great grandfather nodded, "You have also grown up and know how to be sympathetic to the poor."

Xu Changsheng blushed. He was taking the civilian route, making small profits but quick turnover, but it's better not to say it now.

The price has been set, and it is time for mass production, but when Xu Changsheng left, he said, "Leave all the bad bread to me, and I will breed worms."

Grandfather: "..."

Xu Changsheng planned to use the broken bread to breed worms, raise mealworm larvae, and then feed the larvae directly to the plastic to eat, so that the bread would not be wasted.

……

Next, after Xu Changsheng and Uncle Sixteen designed an oven for baking bread, they were free.

The vigorous production in Xujia Village depends on the uncle of the Xu family. A brat like him can't help in terms of physical strength, and the hotels are also under construction in an orderly manner, so he can't help either.

One day, I ran all over the village with a group of children, and ate a basket of popcorn every now and then. The etiquette I learned in the Imperial College could not be used in front of a group of children, and I was developing into a wild monkey.

He seems to have nothing to do now except for the beets in the first base and the birthday gift he has to prepare for Li Er.

As for the two topics of the Shangyuan Festival, it is still early, and there is no need to be busy now.

Let him enjoy the holiday now.

A group of children held bread in one hand and Coke in the other, eating with gusto.

Xu Changsheng was stunned for a moment, did this taste like a hamburger?

Xu Changsheng couldn't help sighing, he still lives freely in Xujia Village, watching him ride on Dabai's back and do whatever he wants, if he was in the Imperial College, the little old man Yan Wenshu would have chased him and beat him with a ruler.

Originally, he wanted to ride a bicycle, but he found that he could not step on the pedals on his calves, so he had to give up.

"Changsheng, let's go eat grapes. When I passed by just now, I saw that the grapes were ripe." Brother Changbai said.

Xu Changsheng was stunned for a moment, his eyes lit up, how could he forget this, his fruit was almost ripe, and I heard that it attracted a lot of birds, a group of Xu family children chased the birds with a pole in a day, and they couldn't catch them Walk.

Xu Changsheng rode a big white and led a group of children towards the square.

Sure enough, before I got there, I heard a group of chirping birds.

Looking up, he saw a sparrow pecking at his grapes.

His face was all black, and he followed a group of children and chased him away with a pole.

"Oh, I'm not leaving yet."

It's a bit too courageous.

Now without pesticides, sparrows have become a disaster.

That's right, in ancient times, sparrows were a more terrible disaster than locusts.

Since ancient times, there have been four pests, referring to flies, mosquitoes, mice, and sparrows.

It was only later that sparrows were poisoned to death due to excessive use of pesticides, and sparrows became fewer and fewer. This was rehabilitated, and the position of the four pests was replaced by locusts. Before, locusts were not enough to make the list.

However, the position of the four pests of locusts was not kept, and they were still almost killed by pesticide poisoning, and the position of one of the four pests was replaced by cockroaches.

In the Tang Dynasty, sparrows were the four pests, let alone protecting sparrows, they did not know how many crops they ruined.

Xu Changsheng poked the sparrow with his pole, and the sparrow jumped onto the pole, as if nothing had happened.

"Oh." Xu Changsheng blinked his eyes. Is this why there are no natural enemies?Sparrows are lawless.

"What can we do? They not only eat our grapes, but also the wheat we dry on the ground."

Xu Changsheng's ears were filled with the cries of sparrows. This season was the harvest season, and it also provided food and drink for sparrows, so the breeding became a bit rampant.

Seeing that he couldn't drive away, Xu Changsheng hurried to harvest the grapes, "Pick all the ripe grapes first."

Some can be rescued.

Picking a bunch of grapes, looking at the pecked grains on it, my heart aches to death.

From time to time, I peeled off the skin and ate one. Now these crops have not been used pesticides, and they are very clean after peeling off the skin.

It's so sweet, no wonder the sparrows are flying here.

Because he didn't bring a basket, he picked the grapes and put them on the ground.

Those sparrows actually flew directly to the ground to peck, which shows how rampant they are.

A group of children were so angry that they shouted.

I picked grapes all over the field, but I couldn't pick the unripe ones.

Looking at the rampant sparrows, he couldn't do anything about them.

I went to pick apples and bananas again, and sure enough, I was pecked a lot.

Mad.

A group of children transported the fruit home, and a group of children were responsible for picking it.

It took a whole day to finish picking the ripe ones, which can be regarded as saving a lot from the sparrows.

He had promised Empress Changsun that he would give her some grapes when they were ripe.

It's a good thing they found out about it early, otherwise they really wouldn't have saved some. If they returned to Chang'an, and Empress Changsun asked him, he wouldn't even know how to answer.

The ripe ones have been picked, but what about the unripe ones on the tree?

Those sparrows don't know if it is cooked or not, they just try it with their mouths, they don't eat the uncooked ones, but they will peck them to pieces.

Xu Changsheng also had a headache. No wonder sparrows are listed as one of the four pests. They can fly and are so small that they can't be caught.

Gritting his teeth, he has nothing to do recently, watching him catch sparrows manually.

The next day, I ran to my grandfather to ask for fishing nets.

Current fishing nets are still made of sackcloth, etc., which are easy to break, but the efficiency of catching fish has improved a lot.

The fishing nets that will come will be hung on the trees, but unfortunately there are still too few, and the fishing nets are very expensive, and it is impossible to hang them on every tree.

If the sparrow comes again, just wait and throw yourself into the Internet cafe.

As for whether the sparrow will come or not?Xu Changsheng didn't need to think about it, he definitely would, because there were still many fruits on the tree.

There was nothing I could do about the wheat drying on the ground, so I had to watch the sparrows fly and chase them away with a pole. Fortunately, they were all in groups, overwhelming, and they would not come one by one, otherwise people would be exhausted.

As for setting up a scarecrow or something, Xu Changsheng also thought about it, but it was probably useless. He was not afraid of people even chasing him with a pole. What deterrent effect could a scarecrow have?

The sparrows of this era do not regard humans as natural enemies at all.

The way to deal with them now is to weave nets and set up more nets in the village. When they know how powerful they are, they will not dare to come.

They now have plastic, which is convenient, and they can be woven into fishing nets and sold in Xu's supermarket.

Xujia Village has long been annoyed by these sparrows. Hearing that Xu Changsheng was going to catch sparrows with a net, he acted quickly and started weaving fishing nets.

But before the fishing net was woven, Xu Changsheng's eyes blinked while eating grapes, so let the young future of their Xu family deal with it.

Xu Changsheng ran to get some tree branches, and then went to the back mountain to burn out long and elastic tape with plastic.

Yes, what he wants to do now is the slingshot, the kind that shoots birds by hand. This is one of the great pleasures of rural children, and the children in the city cannot experience it at all.

Then I made a batch of slingshots and distributed one to a group of children.

"Chang Chang Sheng, what is this?" A group of children didn't know how to use it yet.

Xu Changsheng picked up a stone, put it on the pocket of the slingshot, pulled it, and shot it at the sparrow on the tree.

Unfortunately, the strength was too weak, but the sparrow was startled and flew away.

A group of children froze for a moment, chasing sparrows

Then, imitating Xu Changsheng's movements just now, he started to play mahjong.

By the time the first sparrow fell from the tree, a group of children had gotten into ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

"Chongya, defend Xujiacun."

"Duck rush!"

A swarm of children chasing and beating sparrows.

Don't feel cruel, you wouldn't if a flock of sparrows were eating the food your family depended on.

Awow, run all over the mountain.

I quickly experienced the fun of it.

In the next few days, before dawn, someone called Xu Changsheng downstairs, "Chang Changsheng, get up and play mahjong."

Playing mahjong is not only fun, but also has sparrows to eat.

The beaten sparrows were turned into meat and eaten by them. The taste was a little too much, but there was not much meat.

In this way, the interest is even stronger.

Even when they saw a flock of sparrows, they were less troubled.

Fishing nets have also been made one after another.

A fine and dense net is much easier to use than a fishing net made of linen.

There are too many sparrows. If you set up a net in the morning, you can harvest a lot before noon, which is much faster than they use a slingshot.

There is an extra delicious dish on every table.

Sparrows are known as one of the world's most delicious delicacies.

A group of children arrogantly said, "Hmph, come again if you have the ability, dare to eat our fruits, dare to eat our food."

The adults of the Xu family were also surprised, "I didn't expect that our fishing net can not only catch fish, but also catch birds."

Xu Changsheng was amazed at the number of sparrows he caught every day, because there were too many of them, he could divide a large pot in one day, and even he and Brother Changbai couldn't finish it.

This is the reason why there are no natural enemies, and the consequences of wanton reproduction.

The Xu family has woven a lot of fishing nets, which are already on the shelves of the Xu family supermarket, but there are very few people who buy them, because their nets are different from the previous ones, they are too fine, too dense and too delicate. It's going to break, and it won't last long.

At this time, Chang'an City, above the court hall, is full of gloomy clouds.

"Your Majesty, it's the autumn harvest season, but there are reports from all over the place that the sparrows are infested too much, causing heavy losses to the people. I'm afraid even the tax revenue will be affected." Changsun Wuji said.

Li Shimin didn't care about taxes, and asked, "How is the harvest this year?"

Dasi Farmland Yannian stood up, "According to previous estimates from various places, this year is a bumper harvest year, and there will never be a shortage of food like last winter, but...every time bird damage occurs, the production will lose more than [-]%."

Li Shimin also sighed, it was a bumper harvest year, but...

The sparrow is small and can fly, how can you beat it?

But he still said, "Do you have any good countermeasures?"

The officials are silent, this is a problem that has been going on for many years, if there is a good way, it has been raised long ago.

Moreover, it is only the beginning of wheat harvesting. After waiting for a while, there will be more sparrows. It is a question of how much wheat can be harvested in the field.

Li Shimin also sighed, whether it is a disaster year or a good harvest year, no matter how hard it is, it is his people in the Tang Dynasty.

At this time, Cheng Yaojin was a little awkward.

Li Shimin was taken aback, why does Lu Guogong seem to have something to say?

Generally speaking, generals have nothing to do with this kind of national policy, and they can't come up with any good strategies. They are only used in wars.

There was a dead silence in the golden palace, Li Shimin said, "Duke Lu has something to say?"

All the officials were stunned, especially the civil servants. At this time, why did Duke Lu join in the fun?Don't you just stand there and listen at times like this?

Cheng Yaojin stood up, "Your Majesty, everyone knows that I have joined two Xu's supermarkets in Luoyang, right?"

Everyone was stunned, what is Lu Guogong trying to say?

Li Shimin was also stunned. Don't look at Lu Guogong as a big and three rough, usually careless, in fact, everyone who knows him knows that he is a careful person.

But why mention the two Xu's supermarkets he joined at this time?

Wei Zheng frowned. Before such a big event, how could he suddenly interrupt everyone by bringing a personal matter to the court.

Cheng Yaojin continued, "Everyone knows that the business of Xujia Supermarket is booming, and the one in Luoyang is the same, so the purchases are relatively frequent. People from my house went to Xujia Village to purchase goods two days ago."

The corners of everyone's mouths started to twitch, Duke Lu simply didn't think so, this is a golden palace.

Just about to scold, at this time, Lu Guogong continued, "The person who bought the goods came back and brought me a big bag of sparrows, saying that Xujia Village has too many sparrows to eat. Also, there is a new product in the purchase this time. A strange kind of fishing net, people from the Xu family specifically explained that this kind of fishing net can also catch sparrows besides fishing, and I heard that the bag of sparrows that was given to me was caught with fishing nets."

Fishing nets for sparrows?

Needle drop can be heard on the Golden Temple. Is it a fishing net or a bird net?

People were taken aback when they heard it.

At this time, Qin Qiong also stood up, "When the people from my Qin family went to Xujia Village to buy goods, they were also given a sack of sparrows. I heard it was a special benefit. I think they obviously couldn't finish it."

A few more generals stood up, "I also got a sack of sparrows, and I was wondering how I caught so many sparrows."

All of them are franchisees of Xujia Supermarket.

Li Shimin was stunned, sent so much?Could it be that Xujia Village can really catch those sparrows that fly around and make people helpless?

Fang Xuanling also stood up, "Your Majesty, the old minister also received a sack of sparrows, but the old minister didn't ask much about the Xu Family Supermarket, but he didn't know that there was a fishing net that could catch sparrows for sale."

If he knew, he wouldn't have to wait for a group of generals to bring it up.

Li Shimin nodded, "From this point of view, Xujia Village really has the skill of catching sparrows. Please let someone fetch the fishing nets from Xujia Village to have a look."

Soon someone fetched the fishing net.

Moreover, it was uncle Xu Zheng who sent the net, because Li Er asked people to bring people from the Xu family, and he had some questions to ask.

It was the first time for the uncle to go to the Golden Palace, so he was a little confused.

All the officials of the imperial court watched around the fishing net.

"How does it catch birds?"

"Such a slender fishing net will break after a few uses"

"No, no, this material is wrong, it is very different from the previous fishing nets."

Baiguan looked at the uncle.

Xu Zheng was very confused, and quickly replied, "This is a new material developed by Changsheng. It is very durable. Although it looks slender, it is more durable than previous fishing nets, and the fishing effect is better, and the price is also cheaper."

After finishing speaking, he added, "Changsheng said that this kind of material is not environmentally friendly. It must be recycled when it is worn out, and it will be handled by our Xujia Village."

Baiguan didn't understand. Hearing that the price was cheap, he nodded and asked quickly, "Maybe it is used to catch sparrows?"

Xu Zheng was also taken aback, and actually asked him if the fishing net could catch birds. What kind of strange question is this?

However, he has eaten sparrows for several days. Of course, he knows that these fishing nets are set up on the fruit trees where the food is dried in Xujia Village, and they are the sparrows caught with them.

He replied, "Yes, my Xujia Village uses it to catch sparrows."

There was silence, and then a face full of surprise.

"Your Majesty, we will save the autumn harvest."

Li Shimin was also delighted. With the example of Xujia Village, it must not be fake, and the fishing nets are cheap and feasible. He said, "Go to Xujia Village to verify it. If it is really effective, urge Xujia Village to mass-produce fishing nets and transport them to Datang Shidao."

Uncle Xu Zheng reminded, "Don't throw away the worn-out fishing nets. My Xujia Village recycles them at a high price."

Fishing nets are also part of the plastic recycling scheme.

Its own officials go to handle related matters.

The uncle also went down, walking with the wind, he, a commoner, actually went to the Golden Palace, although he only said a few words.

The originally gloomy and gloomy atmosphere in the Golden Palace has changed.

"This son of the Xu family, he didn't hand over some good things in advance, which caused me to wait for so long."

"That's not the reason."

"If this fishing net can protect the food, even [-]% of the food, the Xu family will be considered a meritorious service."

"This is to save food for the people of the world, and the credit is not small."

Someone suggested, "Your Majesty, the Xu family has been kind to the common people, and please give me a big reward."

Li Shimin thought for a while and said, "The new method of raising pigs proposed by Xu Jiazi last time is beneficial to the people's livelihood. I am still thinking about how to reward him. Now, he has made a fishing net that can catch sparrows. Let's wait for the fishing net to be implemented." , together with rewards."

All the officials nodded, many people looked envious, Xu Jiazi was only four years old, but he has made many contributions and made friends with the prince, so he has a bright future.

The smile on Li Shimin's face was getting bigger and bigger. Xu Jiazi was arranged to enter the court as a representative of a poor family. He thought he was too young and had to wait a few years to see the effect, but he never expected to surprise him repeatedly.

It seems that he is still too conservative, and some paces can be accelerated a little.

And Xu Jiazi, the representative of the poor family that Li Shimin placed high hopes on, was digging out a bird's nest in the back mountain with a group of children.

"Chang Chang Sheng, many sparrow nests, many birds' eggs."

Xu Changsheng thought to himself, no wonder there are so many sparrows in their Xujia Village, and they can't catch them all. It turns out that they all settled in the mountains and gave birth to nest after nest.

Watch him go straight to his lair.

Although sparrow eggs are small, they are especially delicious when baked.

Of course, he would not dare to start a fire on the mountain. It would be a crime if there was a fire.

In addition to smashing bird nests, they also brought fishing nets to catch fish.

There is a river at the foot of the mountain in Xujia Village. It is the time when the fish are fat in autumn. The taste of the river fish is much better than the fish raised in the pond.

Xu Changsheng and a group of children were so crazy that they almost forgot that he was a scholar. Such unfettered happiness is very rare.

When Xu Changsheng and Brother Changbai returned to Xujia Village with fish in their arms and a handful of sparrow eggs, he didn't know that the imperial court had come to let them produce fishing nets.

Big business, eyes are bright, it can make a lot of money.

but……

The great grandfather was talking with the officials who came, "For this fishing net, our Xujia Village only charges the cost and some labor costs."

The official was grateful to Dade, "The common people in the world will definitely remember Xujia Village's favor, and His Majesty will definitely remember Xujia Village's contribution."

The purchase of fishing nets this time will get a lot of compensation from the court. Even so, it will be an extra expense for the people of Datang.

Xujia Village is willing to sell at a low price, which has brought real benefits to the people all over the world.

Xu Changsheng drooped his head and sighed, but after listening to it for a while, he knew that it was a national calamity, and it was indeed not desirable. His Xu Family Supermarket also had the words "beneficial to the country and the people". Ah, some things still have to hold on.

Although he knew that sparrows were extremely harmful in ancient times, he didn't expect the harm to be so harmful.

After thinking about the sparrows who couldn't be chased away all over the sky, he knew that the official was not exaggerating.

Since it is for the sake of the country and the people and does not make money, Xu Changsheng looked at the officials in front of him shyly, "Does Your Majesty know about this?"

The official was stunned for a moment, then smiled, "Don't worry Xu Jiazi, your majesty said that you made a contribution last time in proposing a new method to raise pigs, and this time you saved food for the common people, and you will be rewarded at that time."

Xu Changsheng breathed a sigh of relief, that's all right.

He is not a saint, so His Majesty must know about such good deeds as selfless devotion. Besides, if those who do good deeds are not rewarded, there will be fewer and fewer people who are willing to do good deeds in the future.

Now that His Majesty knew, Xu Changsheng ran to play again carelessly, and asked his great grandfather to give the official some sparrows when he left.

Xu Changsheng thought of a way, which is to fry the sparrows and vacuum them up, and sell them in Xu's supermarket. The taste is really good.

During this holiday, he had a lot of fun, but of course it wasn't all fun.

For example, he is now running around with a group of children, but he still finds time to let them take out popular science books for children to teach them.

He will never forget that every time he preaches, with those confused eyes, he has tried his best to explain it simply, but others still can't understand.

There is only one reason, they have no foundation at all.

If Xu Changsheng wants to spread the seeds of science, the children around him are the best targets.

At a young age, the world view has not yet been fully formed, and the concept is easy to change. It may be faster to teach this group of children than to teach those scholars.

For example, if you ask this group of children now, they can all answer the three forms of water and know how to change the form of water.

This kind of thing was taught to them when they were young, and they would take it deep-rooted in their hearts and take it as common sense, while adults would only take it as a very strange thing.

In the mountains and fields, every child has an abacus hanging on his waist and a coloring book in his hand.

Sitting under the big tree, happily reading the contents of the book.

What Xu Changsheng advocates is to teach students in accordance with their aptitude, and it is not necessary to teach in a quiet classroom.

Looking at the students in front of him, it seems that they are studying very seriously and are very interested.

If you are not interested, it is difficult to learn well.

Brother Changbai is the most embarrassing, because he has learned all these.

However, Xu Changsheng arranged for him the following subjects, so he didn't have time to be fussy.

A few Taoist priests were far away and wanted to get closer to listen, but they were afraid of being discovered.

"What do you think Xu Jiazi is teaching those children?"

"Can't hear clearly, it should be something in that book, but unfortunately we can't understand many things."

"Xu Jiazi tried his best to deny the existence of gods and monsters in that book."

"Hmph, there are monsters in the Huaguo Mountain behind them, don't forget, Songhe's soul is still trapped inside."

……

The holiday time just passed by little by little.

The beets in the greenhouse base are all grown up, and the children of the Xu family licked the leaves of the vegetables, "Why is there no sweetness?"

Xu Changsheng: "..."

You thought it was really made of sugar.

The hang gliding team in the sky has almost finished training and is waiting for the first batch of people to eat crabs.

And Xu Changsheng's vacation is almost over.

There is one more thing before the end, that is, Li Shimin's birthday is coming soon.

Xu Changsheng also thought about what birthday gift to give to Li Shimin, and it could be considered as a gift to the people of Datang.

In addition, although he had a good time during this holiday, he also deeply felt that there were too few entertainment items for children in Datang.

He just made a slingshot, which made a group of children so happy that they played with it every day, and couldn't get enough of it.

A few days away from His Majesty Li Er's birthday, Xu Changsheng asked some young people from the Xu family to help, and began to prepare gifts.

There are two gifts, which will definitely open the eyes of His Majesty the Tang Dynasty.

Why two more?Xu Changsheng was also taken aback, as if he also likes to talk about two topics and two topics in lectures, really two.

Playing with a group of young kids is really the most carefree, but the good times always pass the fastest.

On this day, Li Shimin's birthday came, and Xu Changsheng was going back to Chang'an.

Because after the birthday of His Majesty Li Er, the Guozijian should start school.

A group of children were crying.

Parting is always sad, even for children.

Xu Changsheng said loudly, "Children, take good care of your jelly grass, it will be of great use when I come back."

It is estimated that it will not be long before his beets can be harvested.

After speaking, he rode Dabai and followed a group of clan uncles to Chang'an.

Brother Changbai looked back three times, "Changsheng, when are we going back to Xujiacun?"

Xu Changsheng was funny, before leaving Le, he replied, "So reluctant, why don't you stay?"

Brother Changbai quickly shook his head, "I have to follow you, otherwise I won't be able to eat new and delicious food."

Xu Changsheng: "..."

In fact, he will return to Xujia Village soon this time. One is that the beets are ripe to make sugar, and the other is that his hang gliding base will be ready to open soon.

……

Riding Dabai and entering Chang'an, many people even greeted him.

He is also a well-known celebrity in Chang'an.

Chang'an City is the same as before, but of course there are differences.

Honeycomb briquettes were lit at the door of many people's houses, and the things stewed in the pot gave off an attractive smell.

On the street, there were still people gnawing on bread, and then drinking a sip of Coke, their eyes narrowed as if they had eaten some delicacies from mountains and seas.

Xu Changsheng also ate Coke with bread in this way, and the bread would become very sweet.

There are still a lot of people eating bread on the street, probably because the bread is a civilian route, and the taste is much better than pancakes.

Xu Changsheng also discovered that after tearing open the plastic bag outside the bread, these people did not throw it away casually, but gave it to some beggars directly.

They are all poor people. In the past, they had no money to give these beggars, but now these beggars can collect these plastic bags and go to Xu's supermarket to exchange for food. Why not do it.

It can be seen that the people of Datang are still very simple and kind, and they will do some good things within their ability.

Xu Changsheng also smiled when he looked at it. Many things may not be all bad. For example, his plastic bags are convenient for people, but at the same time, if they are thrown away casually, they will cause pollution. But now, they also feed some poor people who are begging. ?

When Xu Changsheng came to Chang'an this time, he brought one more thing.

That's... big cock.

Their Xu family's chicken has finally grown up, and he can finally eat the stewed ganoderma with chicken that he has been thinking about for a long time.

Hens need to keep their eggs, so he stewed a big rooster, which is equally delicious.

I stewed a pot at the first time, put it in a big pot
