Datang Institute of Technology

While Erdan was still watching people watering, Xu Changsheng took out a pen and paper and began to draw the design.

Don't look at a small pressurized well, in fact, there are quite a few doorways in it.

Fortunately, he understands all the principles, and he can figure out the design drawing by exploring slowly.

Xu Changsheng began to draw, bracket, main shaft, gas cylinder, piston...

One thing occupies a piece of paper, and some things are annotated beside it.

If the Sixteenth Uncle of Xujia Village is very familiar with his painting method now, others probably need him to explain it beside him.

Brother Changbai saw that Xu Changsheng had started to draw the design, so he waited beside him.

Changsheng always likes to throw the unfinished design drawings into the trash can. Every time he puts them away, so as not to let others pick them up. The waste drafts of Changsheng he collects now are put in two big boxes.

A pressurized well is not too much trouble for Xu Changsheng, and he finished the painting during lunch.

Now all the servants of the Ronghua Palace have been driven away by Erdan, and Erdan has to go to pass the meal by himself.

Erdan happily ran away, but came back empty-handed, and shouted before he arrived, "Brother Changbai, go to the Immortal Restaurant and ask for lunch to be delivered."

Xu Changsheng was taken aback, why didn't he eat the meal at the Prince's Mansion?

It's not good to go on like this, others will gossip.

Erdan walked and said, "I've tried every dish, and it's not good."

The Prince's Mansion advocates frugality, but the food is much richer than that of ordinary rich and noble families, but Erdan followed Xu Changsheng's mouth to eat.

Every time there is a good thing, Er Dan is the first to try it. He probably thinks that other people's food should be the same as theirs.

Xu Changsheng frowned, but said nothing.

Letting the Immortal Restaurant to deliver food all the time will definitely be used as an issue, because every time the uncle of the Immortal Restaurant delivers food, he must wish to send the best things, so as not to be charged with extravagance.

He lives in the Prince's Mansion now, so he still needs to be careful.

The meals in the Prince's Mansion are looked down upon by dicks, and they probably won't even eat them. Although Brother Changbai is not as picky as dicks, he won't dislike the food if he eats it deliciously.

Xu Changsheng thought about it, why not start a small kitchen by themselves in the future, just like in Xujia Village, the three of them always make all kinds of things to eat, don't underestimate douchebags, douchebags want to eat, but learn to eat. With a good skill in cooking, Er Dan cares most about food besides his flowers.

Brother Changbai went outside to ask the Immortal Restaurant to deliver lunch, and bought a lot of daily necessities that they lacked to bring in.

Although they brought some things by themselves, they only brought some simple ones, and there were many other things that needed to be bought on the spot.

What Xu Changsheng used for the past 12 years were all the best things from Datang. It is conceivable that Brother Changbai bought the best.

Xu Changsheng said that this time he lived in the Prince's Mansion for a long time, so Brother Changbai bought a little bit more.

In this way, so many expensive things were moved to the Prince's Mansion one after another, many people from the Prince's Mansion came to watch.

As a newcomer who has just entered the mansion, Xu Changsheng will inevitably be criticized.

"Our Prince's Mansion has always been frugal. Isn't he ruining the reputation of our Prince's Mansion by being so extravagant in public?"

Brother Changbai really didn't have the idea of ​​showing off, because Changsheng used these things in his daily life, so he bought them habitually as a matter of course, and had no other ideas at all, but others didn't think so.

"What's so great about being rich? You really think of yourself as a son of a family. If you really are a son of a family, you don't need to come to our prince's mansion to be a steward and go through the back door."

"Xingxin, why haven't you told the prince yet, you see he just came and made our prince's mansion into a mess."

Xinxin fiddled with the flute in his hand, as if he didn't hear it, these people asked him to tell the prince, but that was the prince, he was only a musician, so he wondered why he could talk so easily.

He was able to get along so well in the Prince's Mansion because of some tricks. He was just an inconspicuous musician among the many musicians before.

Until...he accidentally dazzled and saw a painting of His Royal Highness the Crown Prince.

Although he just glanced at it and couldn't see it very clearly, but his memory is quite good...

He began to change his attire.

And the flute in his hand was indeed given by the crown prince, or it was compensated to him.

The prince "accidentally" broke his flute, so he sent someone to send another one.

But others don't know the reason, they only know that the prince sent someone to send Xiao...

In this way, no one in the East Palace would dare to offend him, and everyone knew that the crown prince specially "gifted" a flute to him, which shows that the crown prince appreciates him a lot.

His life in the East Palace suddenly became smoother.

But the increasingly smooth life made him gradually dissatisfied with it.

Intentionally or unintentionally, he passed by the prince many times. For some reason, he made some small mistakes because of fear. The prince just frowned and didn't say anything in the end.

For these small mistakes, most people will receive some small punishments.

In the eyes of others, these are the manifestations of his appreciation by the prince.

He also didn't explain that rumors are secretly passed on among the subordinates, and gossip is punished severely, but in the Prince's mansion, there is no one who has a good relationship in private, so the servants should say it secretly, but they dare not let it go On the bright side, I dare not be bumped into by others.

Then even some of the stewards began to be wary of him.

Like this, he gradually became the head of the musicians, and he was able to speak a word or two with the prince, especially during celebrations and other activities.

In this way, it seems to vaguely confirm the rumor that he is very appreciated by the prince.

Every time these musicians encountered something, they asked him to tell the prince, and he didn't refute it. In fact, only he knew that it was so easy to have a word with the prince.

However, this talent has made such a big fight since he came here, if he is not taught a lesson, wouldn't it be stepping on his head.

Yi Xin ignored the chattering musicians, but walked outside the Prince's Mansion.

Soon he walked into a remote alley and stuffed the prepared silver into a window, "I want you to spread the news about the grand purchase by the Prince's Mansion."

Such extravagance and waste, once the incident comes, how will that person deal with it?The Prince's Mansion is famous for its frugality, how can it accommodate him?

Where there is light, there is darkness, even in Chang'an.

This place was known to him before he even entered the Prince's Mansion.

The reason why he was unpopular in the Prince's Mansion before was not that he was not good at music, on the contrary, he had only a handful of music, but that his previous life was not very glorious, and even a little shameful.

He originally thought that he would never come to this kind of place again, but ever since he saw that person, he always had a familiar feeling, a sense of panic, and this kind of sense of danger from the bottom of his heart made him come here again.

At this time, a voice came from the window, "Not enough."

Yi Xin frowned, gritted her teeth, and took out another bag of silver.

Although these people have always been very courageous, they are unwilling to let them spread rumors about the Prince's Mansion without paying enough.

"Not enough." The person in the window continued.

Yi Xin gritted his teeth, and took out some beautiful accessories. These are his savings over the past few years, and he is also cruel. If he wants to do it, he will do it at any cost.

This time, the people in the window didn't make any more noise.

After he left, he wasn't worried that these people would take the money and not do anything. Although these people were all thugs, they still had some credibility of their own, otherwise no one would ask them to do things in the future.

……

At this time, Xu Changsheng had already taken his design drawings to find Chief Manager Zhou. He was not familiar with the current personnel in the Prince's Mansion, so he had to ask Chief Manager Zhou to find some craftsmen for him.

Chief Manager Zhou smiled, and he didn't have the same serious face towards others, "We have our own craftsmen in the Prince's Mansion, and I will let them go to your place after a while."

Xu Changsheng nodded. He brought a box with him when he came, "Uncle Zhou, this is specially brought for you."

"You child, why did you give me a gift? If the prince finds out, he will have to pull out my skin."

Xu Changsheng smiled, "It's just some worthless things, Uncle Zhou has to accept them."

After chatting for a few more words, they left.

After leaving, Chief Manager Zhou opened the box with a smile. It can be said that he watched Xu Jiazi grow up, so the relationship is quite special, just like the other party's elders.

But as soon as he opened it, his hands trembled. It was a huge Ganoderma lucidum. He had never seen such a big Ganoderma lucidum in the inventory of the Prince's Mansion.

The corners of his mouth kept twitching, just now Xu Jiazi actually said it was a worthless gift...

He sighed, now Xujiacun's business is all over the world, maybe it is really worthless to him, but he still has to tell the prince about this matter, he will take this gift as a hot hand.

Not long after Xu Changsheng returned to Ronghua Palace, a group of craftsmen came over.

Xu Changsheng was taken aback. He couldn't have so many people. Those who didn't know thought he was going to do some big project.

He quickly said, "Just keep one or two."

As a result, a group of craftsmen said, "No, Manager Zhou specifically told us that we can't leave unless we meet your requirements."

Xu Changsheng: "..."

Well, if there are more people, then there are more. Anyway, his design drawings still need to be adjusted. Let them refer to them together, and maybe they can get them out quickly.

He took out the blueprints, and brother Changbai stood by. He had to prevent these people from taking Changsheng's blueprints.

Xu Changsheng looked at it with a smile. I don’t know why. Brother Changbai liked to collect his design drawings since he was a child. He told him all about it. The manuscripts are collected in two large boxes.

As soon as the design draft was taken out, these craftsmen were stunned, which was different from what they had seen before.

Xu Changsheng also knew the situation. He was used to drawing like this, and he could only draw like this. In his opinion, this way of drawing is more accurate. Look at his perspective drawing, how beautiful it is.

Xu Changsheng started to talk about each design very seriously, even the usefulness.

These craftsmen deserved to be able to enter the Prince's Mansion, so they quickly understood.

"Can water be pumped out in this way?" But I still have some doubts. Although I know how to make this thing, I don't quite understand the principle.

Xu Changsheng smiled, "Do you know if you make it and try it?"

A group of craftsmen began to discuss and even put forward some opinions of their own.

Xu Changsheng didn't care anymore, let them figure it out for themselves.

Erdan was arranging for someone to arrange the things that Brother Changbai bought back. When he came out, his eyes were smiling, "Chang Changsheng, let's make wine. Brother Changbai bought a lot of grapes just now."

The wine he mentioned is different from modern wines. It is a fruit wine without too much processing. Like cider lychee wine, it tastes very refreshing fruit wine. The alcohol content is not high, but it is very sweet.

Ever since Xu Changsheng taught Er Dan how to make fruit wine, the little alcoholic fell in love with it.

Xu Changsheng also likes to drink it, saying it is wine rather than a drink.

Xu Changsheng's eyes lit up, and he replied, "Okay."

Erdan brought out the grapes happily, and went to wash the grapes. He had to wash them one by one. Changsheng loved to be clean, and he would not eat them unless they were cleaned.

Brother Changbai said, "I have tasted this grape, and it is not as sweet as our Xujia Village."

In the current Xujia Village, the fruits are not like the ones around the square in the past. There are a lot of grapes alone. At a glance, they are all grape racks, and there are many other fruits. Xu Changsheng has never been short of fruits in the past few years. .

Brother Changbai originally planned to go to Xu’s Supermarket to get his own grapes, but when he went, they were gone. As soon as the grapes in Xu’s Supermarket were put on the shelves, they were all sold out in minutes. How could he get them when he went? The uncle of the clan said, and left some for them in the future, and then went to the West Market to buy some other people's grapes.

Although not as sweet as their grapes, he couldn't make the trip in vain, no.

Xu Changsheng tasted one, and it had a bit of a sour taste. Eating it directly was indeed much worse than the taste of the Xu Family Village's self-grown one, but the sour taste would not affect much when used to make wine.

Some of the grapes were distributed among the craftsmen.

Xu Changsheng went to find another big glass jar.

It is not uncommon for glass jars to be sold in Xujia Supermarket.

Wash the jar clean, then put it upside down in a cool place and let it cool down. In such a bright sun, it might explode if placed in the sun.

Then he ran to help Erdan wash the grapes, Erdan frowned while washing, "The grapes are not as big as our Xujia Village's, and not as sweet as our Xujia Village's. I won't let Brother Changbai go shopping next time."

This little idiot actually despises Brother Changbai.

Wash the grapes and cool them down. When the water is dry, put the grapes in a glass jar, put a layer of grapes and a layer of white sugar, and then seal the glass jar.

Just wait for it to ferment now, and then use a filter cloth to filter out the pulp later.

It was such a big glass jar that even Erdan and Xu Changsheng couldn't move it, so Brother Changbai carried it in and put it in the corner of the storage room. It looked pretty good.

Erdan watched it for a long time before coming out, and then he drank fruit wine, thinking about it, he licked his little tongue.

Because Xu Changsheng decided to open a small stove by themselves, Brother Changbai also bought a lot of stoves.

There is a kitchen in their palace, which can be used just right.

The whole palace seemed to have a breath of life.

The three of them went to get the stove again.

In this way, the three of them were very happy, and the work was not tiring at all, and they could exercise their bodies, so they didn't call the servants of the Prince's Mansion to help.

When they were in Xujia Village, they didn't have servants, that's what they did, and they lived happily.

After they finished the stove, when they came out, the pressurized well was almost finished.

The materials and tools are all available in the Prince's Mansion, and these craftsmen made them after studying for a while.

Xu Changsheng shouted, "Damn, come out and try your pressurized well."

Erdan ran out of the kitchen, and he was still trying to see if the kitchen was working well.

Erdan ran towards the water well with a full face of excitement. His flowers were the most important, and he had to try to see if the water pressure well that Changsheng said was working well.

Xu Changsheng pointed to the handle of the water well, "Damn, go and try pressing it."

Erdan scratched his head, not knowing what to do, so he obediently ran to grab the handle and pressed him up.

Press your ears and listen. There is a gurgling sound in the well.

The more you press, the harder you get.

The craftsmen around also looked at it, so many of them worked on it all afternoon, and they also wanted to know the result.

Just looking at it, white water sprayed out with a "wow".

Erdan yelled happily, "Tap water, tap water."

However, as soon as he stopped, the water boiled for a while and then disappeared.

I couldn't help being taken aback, but the water in their Xujia Village would keep gushing out.

I pressed it again, and the water started to bubble up again.

Scratching his head, it's a bit different from Xujiacun's, but it's much more convenient for him to water the flowers this way.

Brother Changbai has already taken two wooden barrels to catch the water there.

Xu Changsheng said to Erdan, "You ask Brother Changbai to go to Xu's Supermarket to get you a water pipe to connect it to it, and then let Brother Changbai come to press it, and you can just water it, it's the same as before. "

Erdan’s little head pointed out that as long as you keep pressing, the water will come out. From now on, let Brother Changbai press the water every day. Anyway, the grandfather said that Brother Changbai is so strong that he has nowhere to use it.

Brother Changbai: "..."

The Zhou people's craftsmen's eyes lit up, "It actually pumped up the water."

"It's really convenient. You don't need to lift the bucket into the well to fetch water."

"Compared to this, it is not only laborious but also troublesome."

Brother Changbai went to send these craftsmen who took one step at a time and turned back three times. Xu Changsheng asked him to give them the unused grapes, anyway, they probably wouldn't eat them themselves.

While Xu Changsheng didn't see it, Brother Changbai hurriedly said fiercely to these craftsmen, "This is our thing, you are not allowed to leak it out, or I will have to talk to your crown prince."

A group of craftsmen: "..."

The craftsmen who can enter the Prince's Mansion know more than those outside, so they nodded with some pity.

Only then did Brother Changbai go back satisfied.

With effortless water, Er Dan shouted to Xu Changsheng, "Chang Changsheng, what do you want to eat tonight?"

They fired themselves tonight, just like they did in Xujia Village.

Erdan was very happy, he made whatever he wanted to eat, he made it himself, Changsheng told him that the dishes made by others could not be washed cleanly, he remembered clearly, it was better to eat the dishes he washed himself and eat at ease.

Xu Changsheng didn't even know what Brother Changbai had bought, so he ran to the kitchen to have a look. It was quite complete, no wonder it took him a long time to move the bags.

After looking at it, he said, "Let's go for the hot pot. Brother Changbai bought everything anyway."

Erdan's eyes lit up. He likes hot pot the most. He and Brother Changbai like spicy food the most. They are the spicy kings of Xujia Village.

Erdan said, "That's still short of a honeycomb stove and honeycomb briquettes."

Xu Changsheng nodded, "There are also devil's spices and condiments from our Xujia Village. Immortal Restaurant should have them."

Their unique condiments, such as Devil's Spicy, Onion, Ginger, Garlic, Pepper and Pepper Thirteen Fragrances are not sold, because they are all unique secret recipes of their products and cannot be disclosed to others.

However, there are fairy restaurants, and they will put some in the dishes, so that their fairy restaurants are now the number one restaurant in Chang'an.

Xu Changsheng said to Brother Changbai, "Take some other spices too, so as not to run around all the time in the future."

Brother Changbai nodded, and ran to get people to deliver things again. He was always busy at the beginning, but it was just running around.

Xu Changsheng and Erdan started to wash vegetables. Brother Changbai probably didn't know what to eat, so he bought a little of everything.

Er Dan licked his lips happily, "The dishes I wash are the cleanest."

While Xu Changsheng and the others were happily preparing dinner.

Some local hooligans in Chang'an have begun to intentionally spread the news.

"Did you pay attention, someone went to the most expensive cloth furniture workshop and jewelry shop in Chang'an today to raid."

"Why don't you know, I heard that the best pieces of fabric that just arrived have been bought, and there is nothing left."

"Not only that, the treasure of the furniture workshop, the cabinet made of high-quality sandalwood was also bought away."

"The owner of the jewelry shop is also very happy. I heard that the most expensive jade hairpins have been sold. He moved things with a group of people. It should be the same person. I don't know who it is?"

"I don't know about that, but the things were moved into the Prince's Mansion."

Maybe no one pays attention to being generous, after all, there are many rich people in Datang, but it is different when it is connected with the Prince's Mansion.

Royal is no small matter.

Soon the news spread, and even some admonishing officials got the news, especially some officials on Li Tai's side, who were more concerned. This was a good opportunity to damage the prince's reputation, and they had to think about it carefully.

In the prince's mansion, a group of musicians such as Yixin are also gossiping.

"Do you think it's strange? I just heard people say that the new guy is actually building a stove by himself. It looks like they want to cook for themselves?"

"How is it possible? They purchased a lot of things in a big way. I took a peek and saw that they were all the best. They don't look like people who are short of money."

"No, I saw a few bolts of cloth they brought in, and I saw the crown prince wear them in that quality and material."

I can't understand more and more.

However, the corners of Xinxin's mouth turned up, and finally realized that extravagance in the Prince's Mansion is not feasible?I want to change everyone's thinking in this way, but it is too late.

If Xu Changsheng knew what he was thinking, he would definitely say something, thinking too much.

They made their own food, not because Erdan was greedy and looked down on the meals of the Prince's Mansion, and he felt that it was not good to let the Immortal Restaurant deliver food to the Prince's Mansion every day, so he made it himself.

As for Brother Changbai's shopping, he used to be responsible for buying Xu Changsheng's things. He would not change his habits inexplicably just because he came to the Prince's Mansion. He didn't realize that there was something wrong with him at all. He didn't That's it?

At first he didn't do well in shopping, and was scolded by Xujiacun's uncle. Is this for longevity?

The Xu family's children are raised poorly, but they are raised richly if they live forever. The body of Changsheng is the most important thing, and other theories are put aside first.

So in the long run, Brother Changbai developed this habit. Anyway, he has to buy the best things for Changsheng.

Because I just moved into the East Palace, I bought a lot of things.

When Chief Manager Zhou arranged for people to deliver the daily necessities ordered by the prince, he was also a little confused. There was nothing missing. It took only one day, and he took the things out of the warehouse as soon as possible.

He had to go back with his things, and he had to talk to the prince about it.

When Li Chengqian came to Ronghua Hall expressionlessly, he was still thinking, why didn't he accept his things?

In fact, Xu Changsheng never thought that Li Chengqian would arrange these things for him, so he asked Brother Changbai to buy something when he saw what was missing. Brother Changbai just saw what was missing.

When Li Chengqian arrived, he saw three people "sizzling" around a stove.

"Erd, how much chili did you put in?"

"Not many, really."

Believe in you, there are ghosts. It's so spicy, but it's so refreshing to eat.

Seeing someone coming in, Xu Changsheng was stunned, Li Chengqian?

Standing up, he said, "His Royal Highness, have you eaten yet? How about we go together?"

This is a feudal society where imperial power is paramount, and Xu Changsheng knows what he should be. If he dares to say that everyone is equal, he is sure that he will never see the sun the next day.

Therefore, he has been choosing between his good friend and the prince, being friendly without losing his awe of the imperial power.

As soon as I finished speaking, I felt something was wrong. How could I ask the prince to join the pot that they had all eaten.

Change your mouth now.

But before he could say anything, Li Chengqian actually sat down beside him, looking like he was waiting for the dishes.

Li Chengqian is also quite interested, what is this food?feel good.

Brother Changbai ran to prepare the bowls and chopsticks.

So four people surrounded a stove.

Ordinary people would probably not dare to sit with Li Chengqian like this.

But Brother Changbai followed Xu Changsheng to the Prince's Mansion since he was a child, and Li Tai studied some scientific foundations with Xu Changsheng in Li Chengqian's study, so he was familiar with Li Chengqian since he was a child, and he didn't feel uncomfortable sitting together .

As for Erdan, he only cares about eating now, and he doesn't care about the rest.

Xu Changsheng hurriedly put the scalded mutton to Li Chengqian, "Your Highness, try the taste."

They're mostly lamb pot today with a little bit of everything else.

Li Chengqian nodded.

Normally, he wouldn't sit down, but for some reason, when he saw Xu Changsheng, he just wanted to sit together in such a relaxed way. He didn't really want Xu Changsheng to be like everyone else, submissive to him, not even daring to raise his head to speak.

Li Chengqian took a sip and was taken aback for a moment. The taste was surprisingly good, and he said, "What's the way to eat this?"

Xu Changsheng replied, "This is called hot pot. If the ingredients are good, it is very delicious. It is most suitable for eating together like this."

Li Chengqian looked at the burning stove, hot pot?It's quite appropriate, and I don't know if it's a psychological effect, even he feels that this hot pot should be eaten around like this.

Xu Changsheng began to pick up food for Li Chengqian again, and he himself took a bite from time to time.

Seeing Li Chengqian take a bite, he asked with a smile, "Is it delicious?"

Very happy.

Mutton has a fishy smell, but you can't feel it at all when you eat it this way.

When Xu Changsheng asked, Li Chengqian nodded.

Unexpectedly inexplicable harmony.

From the evening to the beginning of the Chinese lanterns.

Li Chengqian probably never thought that he could eat so much for so long.

Even the vegetarian dishes are very delicious.

He suddenly realized that it seemed that their meals in the East Palace were not as delicious as the Xiaozao here.

He also heard that Xu Jiazi started a small stove, and at first he didn't agree with it. How could Xu Jiazi do this kind of thing by himself?

The mood is a bit complicated. Although the meals in his East Palace are not as good as those of the imperial chef, they are not bad either.

The four of them were a little full, and the lights were lit outside, which was very bright.

Xu Changsheng ran to fetch water from the well and washed Li Chengqian. After eating hot pot, there would always be a smell of fireworks.

Li Chengqian watched Xu Changsheng pressing the water without blinking his eyes, and couldn't help being taken aback when the water splashed out, "Tap water?"

Xu Changsheng shook his head, "No, this is a pressurized well, and the water has to be pressurized to produce water, which is not as convenient as our Xujia Village."

Li Chengqian looked at the well without blinking his eyes. It was not as convenient as Xujia Village, but it was much more convenient than their Chang'an.

Take their Eastern Palace as an example. Because of the large population, it takes a lot of people to fetch water every day, and it is very difficult.

But this pressurized well actually gets the water out directly, which is quick, convenient and labor-saving.

Can't help but ask, "How long does it take to make something like this?"

Xu Changsheng came over with water, wet and dried the handkerchiefs, "The handkerchiefs are all newly bought."

Li Chengqian took over.

Xu Changsheng said, "Just finished it this afternoon, and let the craftsmen in the mansion do it."

Li Chengqian asked a few more words.

Xu Changsheng probably also saw that Li Chengqian was interested in this pressurized well, and asked, "Your Highness, do you want the Prince's Mansion to be a pressurized well?"

Li Chengqian replied: "The whole of Chang'an."

Xu Changsheng: "..."

As the crown prince, he did think more than him, so he also wanted to make it easier for Erdan to water and cook for them.

Xu Changsheng nodded, "That's not a problem. You can do it yourself. It's simple. The craftsmen in the mansion probably have already learned it."

"Well, you did a good job." Suddenly Li Chengqian said, and then reached out to touch Xu Changsheng's head.

Xu Changsheng blinked his eyes in a daze, just like he usually likes to touch Erdan's head when he sees Erdan is a little confused.

Li Chengqian was also stunned, why did he let the flow take its course and pat Xu Jiazi's head.

Li Chengqian put his hand back blankly, as if nothing happened.

Xu Changsheng: "..."

That's okay too?Obviously touched him.

But he was fine, and took the handkerchief from Li Chengqian's other hand.

Li Chengqian left.

Xu Changsheng and the others also put away the stove. This stove is very useful. They will stew chicken soup tomorrow, because Brother Changbai said that the clan uncle asked them to get the chicken tomorrow, and the caravan from Xujia Village will bring them chicken and meat tomorrow. The eggs come from their own running pheasants and native eggs.

After Li Chengqian walked out of the Ronghua Palace, he raised his hand while walking, and just looked at it like that.

The guards following behind looked at each other, what's wrong with the prince?What a weird move?It looks kind of... silly.

Li Chengqian will still deal with the memorial for a long time at night, and he is going to the study now.

When he was about to arrive, a figure came over at this time, "See Your Highness the Crown Prince."

Li Chengqian nodded, he was somewhat familiar with this person, he was the musician of his East Palace.

At the beginning, he was a little strange that he looked somewhat similar to Xu Jiazi.

But now that I saw Xu Jiazi, I realized that he didn't look like him at all. Xu Jiazi wouldn't be like this person now, so cautious that he didn't even dare to look at his face.

Xu Jiazi dared to look at him with his chin on his hands, saying that he was good-looking, but no one had the guts.

Molesting the prince?I'm afraid that only he can do it. His heart beat so fast at that time.

Li Chengqian didn't even stop, and walked straight forward.

Yixin opened his mouth, he had come here to accuse someone of being extravagant and affecting the reputation of the Prince's Mansion, but he didn't dare to say anything.

Every time he saw the prince, he didn't even dare to raise his head to take a look.

He regretted it very much, the crown prince didn't even look at him.

In the past, he could at least feel the prince's eyes glance over him.

Suddenly, an incomparable sense of loss filled his heart, all because of that person, when he came, the crown prince refused to give him even a little charity.

He doesn't even know how he came up with this idea, but that's what he thinks now.

Turn around and walk outside the Prince's Mansion.

"Musicist Xinxin, curfew is coming soon." The guard reminded.

Said that he left without looking back.

I came to the alley that was deserted during the day again.

He knew that his previous life was very dirty, but he only wanted to have a little contact with the prince, even a little bit, he didn't want to be forgotten by the prince in some unknown corner.

"I want you to spread the news that the prince and the musician are very happy and have a very good relationship."

After a while, there was no reply from the window.

Yixin put all his savings in it, then turned around and ran away.

When he came out of the alley, there was some cold sweat on his face.

He was astonished by his behavior just now.

But in this way, the prince should look at him more.

After doing everything, he didn't think so much, so he hurried to the Prince's Mansion, and the curfew started immediately.

The next day, above the Golden Temple.

Li Chengqian was the first to stand up when the court meeting started, "Father, what do you ministers think of the tap water in Xujia Village?"

All the officials in court have been to Xujia Village, not to mention hundreds of officials, even the people of Chang'an have not been to Xujia Village.

All the officials were taken aback, why did His Royal Highness mention this?

Tap water must be good, it looks like it makes people like it, but they can only envy, they have already asked the people in Xujia Village, Chang'an does not have that condition, even if they want to get tap water.

Li Shimin was also taken aback, and then his eyes flashed. He knew that Xu Changsheng was in the Prince's Mansion, and asked, "Why did you suddenly mention the tap water in Xujia Village?"

Li Chengqian replied, "Although Chang'an cannot realize running water, my friend provided a method similar to running water, which is very fast, convenient and labor-saving. I want to implement it throughout Chang'an to benefit the people."

It's the prince's friend again!

Baiguan was taken aback.

And Li Tai's hands were trembling, and he started again.

It was exactly the same as it was more than ten years ago, first it was mosquito coils, and now it was something like tap water, but it was just two or three days.

After more than ten years of silence, the Xu family... must have appeared.

Li Tai observed Li Chengqian without blinking his eyes, never wanting to escape his eyes.

Li Chengqian was passing a stack of design drawings to the hundreds of officials in the hall for circulation.

"This is a pressurized well. You only need to repeatedly press down on a handle, and the water will flow out continuously. You don't need to fetch water as much as before." Li Chengqian said.

Baiguan looked at the design drawing, they were not craftsmen, so they probably couldn't understand it, but they looked at the design drawing, and they knew that the crown prince had already made up his mind about this thing.

The blueprint was sent to Li Tai but stopped, "Atmospheric pressure, this is the principle of atmospheric pressure."

He studied with Xu Changsheng for a period of time, and some things were half-understood.

Everyone was stunned, and some people who didn't know it were very strange. Why did the king of Wei know the design of the prince's friend?

It stands to reason that King Wei and the prince are in the same situation, so they must not be able to get along with the prince's friends.

Some ministers who knew something about the past thought that it seemed that it was really made by Xu Jiazi. King Wei had learned something from Xu Jiazi, so it's okay to recognize it.

Li Chengqian glanced at Li Tai, but said nothing.

Li Shimin looked at it, "If it is true as the prince said, it will be miraculous, and it can also provide convenience for the people. What do you think?"

Many ministers came out and said, "Yes."

Can Xu Jiazi's things be bad?

These people have some memories of Xu Jiazi.

And some officials were a little dazed, shouldn't they let them see this kind of thing before making a decision?

Can the water come out continuously with just one pressure?Don't they find it amazing?

Why don't you even look at it?

But look at the people who came out to speak, they are all veterans for many years, including Prince Wei Wang's side.

Today is also considered strange.

Do not follow the steps.

What made them even more bizarre was that Li Shimin also said, "In this case, the crown prince will arrange to implement it in Chang'an."

Without a priori?That's it.

Things are a little weird today.
