Datang Institute of Technology

In the next few days, Uncle Sixteen was doing his best to build the stone mill, while the others, holding a big mallet, pounded the fried beans in the stone mortar.

Xu Changsheng has already said that it won't be such a hassle until the stone mill is finished in two days.

It's just that these people didn't listen in a daze, and they kept messing around.

"Changsheng, we make it ourselves, it doesn't take much effort."

How could they stop? It was oil. Seeing the oil dripping drop by drop, they wished they could squeeze more oil and sell it. They were so poor.

Xu Changsheng pouted, you guys like to mess around, seeing how happy they are, probably won't be able to persuade them.

Backward productivity.

Xu Changsheng found an uncle who was going to Chang'an, and asked him to help deliver the letter to the uncle's mansion.

Then go back to your thatched hut.

He has neglected Dabai these few days, so he needs to comfort him.

As soon as he entered the room, Dabai pounced on him and stuffed him under the thick fur.

Oh, Dabai is too clingy.

Xu Changsheng crawled outside, but was pushed back by Dabai.

Xu Changsheng: "..."

Well, he slept with Dabai in his arms, warm, his eyes smiling like crescent moons.

A few days later, Uncle Sixteen hit several stone mills.

A group of people gathered around to watch it again.

In the past, only the uncles and aunts who were close to Xu Changsheng came to visit, but now even those who live far away come running over.

Isn't it just a stone mill?How come it's like finding some treasure.

Xu Changsheng rode on Dabai's back, Dabai has been too clingy recently.

"Changsheng, how is this stone mill used?" Someone couldn't help asking.

Xu Changsheng yawned, Xiaopang put his hand to his mouth and said, "Uncle Sixteen knows how to use it!"

His small body can't move the stone mill.

The stone mill made is relatively large, because the beans of a village need to be ground, and a small one is useless.

Uncle Sixteen still looked at Xu Changsheng in a daze. To be honest, when he built the stone mill, he never thought it would be of such a great effect. The stone mortar in the village probably won't be used in the future.

Seeing everyone looking at him, Uncle Sixteen quickly scooped up a large bowl of fried beans and poured them into the grinding center, then pushed the handle in a circle.

Xu Changsheng explained from the side, "Pour the beans into the mill, and then push the stone mill. Isn't there an old scalper in the village? You can use it to pull the mill in the future."

Poor old scalper!

Stone mills have been beaten several times, and one cow is definitely not enough, and someone has to push it.

But seeing how eager these uncles and aunts are, I don't mind at all.

Let's just leave it at that, anyway, my grandfather must be reluctant to buy livestock.

"Look, there is something coming out of the cracks in the rocks. It's beans, so thin..."

Uncle Sixteen added more beans.

"It's much finer than ours, and it's so fast."

"Wow, I fed beans in, and what I spit out turned into crumbs."

The children of Xujia Village named Stone Mill, Pac-Eating Stone Monster!

Xu Changsheng: "..."

Feudal superstition, that is a stone mill.

The people in the village gathered all the beans together, and then worked together to grind the beans and squeeze the oil.

The whole village wafted out a smell of beans.

The great grandfather happily arranged, "Let's squeeze some first, and then buy beans back after selling them."

The oil is put into bamboo tubes, which are cut in the mountains behind, and there is no money.

A bamboo tube of oil is about a catty, and the selling price is 120 renminbi, which is much cheaper than animal oil, but the benefits...

Xu Changsheng smiled, "I can't say it, I can't say it, my grandfather has a dark face and is insulting to the gentleman, how can it be sold so expensively, but the grandfather kept touching the bamboo tube, which shows how much he likes it."

……

Soon it was time to go to Chang'an City to sell oil, but Xu Changsheng didn't go.

Because Dabai kept clinging to him, Dabai couldn't enter the city.

A lot of the Xu family's children went, and they had to settle accounts with them, and the abacus was ringing all the way.

Today in Chang'an City is destined to be a lively day. A kind of bamboo tube oil called "Xujia soybean oil" has become popular throughout Chang'an, and the supply is in short supply.

Can it not be popular?Although it's the first time I've seen this kind of oil, no matter its price or strong oil fragrance, it's irresistible.

The life of the residents in Chang'an City is relatively good, but the long winter still has some impact on them, especially the skyrocketing price of food, which is getting higher and higher every day, and they understand the truth of saving as much as possible.

Besides, this oil is no worse than the oil they used before, and the fragrance is even stronger, pour the oil into the pan and heat it up, you can smell it all over the street.

Many people kept asking how the Xu family's oil was sold so cheaply, which made the grandpa, who had lived a life of nothing, blush with embarrassment.

If they knew the cost of the oil, Xu Wenyuan felt that he would leave a shameful mark in the history books.

The rest of the Xujia Village didn't care, they took the money and laughed so hard they couldn't even close their mouths, and next time they squeezed some more to sell.

The oil was sold out soon, so Xu Wenyuan took a few bamboo tubes of oil to see his granddaughter Xu Changying.

Xu Changying looked at the oil with a strong fragrance in his hand, and was stunned. When did Xujia Village become so rich?

Xu Wenyuan smiled, "It's all made by Changsheng drums. We came to Chang'an this time to sell oil. This child is the lucky star of our Xujia Village."

"...Grandfather, selling oil is different from selling bean sprouts in the past. After all, you have to have a fixed shop. You can use my shop. It's empty anyway."

Since Xu Changying won the head of the Poetry Association last time, and also had the top-quality wolf hair bestowed by the prince, her reputation has risen. Her status in her husband's family is quite different from before, and she is still in charge.

Xu Wenyuan originally wanted to refuse, but after thinking about it, Chang Ying was not good at taking care of it, and he had a facade but no income. It was better for him to rent it than to someone else, and he couldn't treat his granddaughter badly.

Also no longer refuse.

When Xu Wenyuan left, Xu Changying was still asking, "Why didn't you bring Changsheng this time? I'm still thinking about that tiger-headed little guy."

Xu Wenyuan smiled, "Changsheng has a big tiger, and he insisted on following him every step of the way. It was inconvenient to enter the city, so I didn't follow him."

Xu Changying: "..."

Grandpa was probably joking, who can stay with the big worm?Changsheng is not a mountain spirit!

……

Compared with the hustle and bustle of Chang'an City today, there is a place where the hustle and bustle is not too much.

That is... above the Golden Palace.

Li Shimin's face was gloomy, "Now that the winter is prolonged, food prices in various places have skyrocketed, and officials in remote areas have reported that famine has formed. Do you have any good solutions?"

As an emperor, but also an emperor with black spots and a sense of shame, Li Shimin can be said to be conscientious, trying his best to make himself a wise king.

But maybe it was really his punishment for killing his brother and seizing the throne. No matter how hard he tried, since he ascended the throne, he has always encountered some natural and man-made disasters every year.

In fact, the issue of insufficient food for the winter is not only raised today, it is raised almost every day.

However, the grain in the granary has already been distributed to various places and has been used up. What else can be done?The quantity of food is limited, and it cannot be added out of thin air.

As in the past, the courtiers argued endlessly, some said to crack down on unscrupulous merchants who raised food prices, some said to increase income and reduce expenditure, act frugally, and follow suit...

But these methods are easy to say, but they are not necessarily implemented, and... they are all palliatives, not the root cause, with little effect.

Li Shimin sighed, is it true that the heavens are not happy with my Datang?

At this time, amidst the quarreling voices, a person stood up, "Cui Zhitong, magistrate of Chang'an County, on behalf of the Cui family, proposes a plan to increase the existing grain by five times within three days."

The voice is not loud, but it can be heard in the whole court.

Everyone has only one idea, this person is probably crazy.

Of course Cui Zhitong knew how to say it to attract attention.

Li Shimin frowned, increasing the food five times in three days?

"Cui Zhitong, do you know what a crime it is to speak falsely at this time?" Li Shimin said.

"I know." Cui Zhitong replied unhurriedly, everything was arranged properly and everything was safe, the credit definitely belongs to their Cui family.

"Then tell me what your plan is, I'm very curious."

Almost everyone looked at Cui Zhitong, why does this person look confident?

Cui Zhitong cupped his hands, "As you all know, not long ago, a vegetable appeared in Chang'an City, which is very popular."

"But the bean sprouts that appeared not long ago?" asked an old man with a green beard. It was Fang Xuanling, the prime minister at the time. What does it have to do with your plan?"

Cui Zhitong said loudly, "It is true that the bean sprouts were discovered by a farmer in the mountains under special circumstances, but my Cui family went to the field to investigate, and after hard research, we made a major discovery."

Someone whispered, "People from the Cui family have indeed been running out of Chang'an City recently, and I wonder what they are doing..."

Seeing that Cui Zhitong spoke clearly and logically, Li Shimin couldn't help asking, "Any important discoveries?"

Cui Zhitong cupped his hands, "Return to Your Majesty, after research, my Cui family discovered a method that can grow one catty of beans into five catties of bean sprouts in three days. This method is also feasible even in winter, and it does not occupy arable land."

Now that the snow is covering the ground, the arable land will definitely not be used.

There are also these smart people above the court, and they instantly thought of the key point.

If it is on weekdays, this method is just another dish for everyone’s table, but when the famine is coming, if this method is promoted in various places, instead of eating bean rice and eating bean sprouts, is it possible that they will not be able to survive the winter?

Li Shimin stood up suddenly, "Is this method really as you said, can turn a catty of beans into five catties of bean sprouts in three days? Even in this cold winter?"

"Return to Your Majesty, the Cui family has repeatedly verified that there is absolutely no problem."

Cui Zhitong mentioned the Cui family repeatedly, but everyone knew what he meant.

As long as his method is really effective, the Cui family will definitely not be able to get away with this credit.

There is a lot of discussion in the court, is there really such a magical method?It not only grows vegetables in winter, but also does not occupy arable land. It takes effect within three days, and the output doubles by five times.

Cui Zhitong cupped his hands, "Your Majesty, I have already prepared the finished product and am waiting outside the hall. I can let the adults see the authenticity."

Everyone looked at each other in blank dismay, even the finished product was ready, it seemed to be true.

"Xuan!"

Huge dustpans were brought in one after another, and they were covered with white and tender bean sprouts without any soil.

A group of bigwigs formed a group like children.

"It's exactly the same as the bean sprouts that our family bought not long ago."

"There is no trace of soil. It seems that there is really no need to occupy arable land."

Even Li Shimin came down to watch and praised again and again.

The problem that had troubled the court for many days was actually solved by a wonderful method.

The Cui family made a great contribution this time.

The corners of Cui Zhitong's mouth turned upwards, the credit goes to their Cui family.

Almost everyone thought so, except... Standing at the top left of the court hall, Prince Li Chengqian in black clothes frowned at Cui Zhitong.

Li Chengqian couldn't help thinking of a letter that made him laugh and cry.
