Wei Zhigu stood there and emphasized: "The important matter of the people of the Tang Dynasty. ”

"Yes, Wei Shangshu hurried back to the court meeting." Li Chengqi nodded.

"Water conservancy matters." Wei Zhigu added.

"Wei Shangshu did not immediately convene a meeting of officials from the Ministry of Industry, and Zhuangzi did not care about Datang Water Conservancy." Li Chengqi still has a blockage.

"The well that Li Yi Zhuangzi pressed and pressed, Qin Tianjian said that there will be a drought this year, and the well on Zhuangzi is good." Wei Zhigu said specific things, to technology, pressure well technology.

Li Chengqi didn't rush to catch up this time, he thought for a while, and said: "Wei Shangshu will go back, and I'll talk to you when the king returns to the palace in the afternoon." ”

Wei Zhigu: "I want to ask in person." ”

Li Chengqi was silent.

"Okay, the old man will leave." Wei Zhigu took the glasses, got into the car and turned his head.

Li Chengqi specially ran to the pressure well, and the windmill had been withdrawn, pumping water to make ice continuously.

The pressure wells are still used daily, and even if there is no continuous flow of water after the beginning of spring, it will not freeze.

Due to poor sealing, when the well is not used for more than half an hour, the water inside will seep down.

When you use it again, you need to take a basin of water and pour it in, press it back and forth, the air will be discharged, and the water will be pumped up.

The people in the kitchen had just pushed away two large buckets of water, and Li Chengqi stood there, pressing it up and down, watching the water flow out.

"Brother Yi said that this well was specially made to prevent children from going to the open well to get water, what does Wei Zhigu want it to do?" Li Chengqi seems to be talking to himself.

Jin Ju, the palace maid who stayed behind, said: "Thinking about it, Wei Shangshu is also afraid that the child will fall in." ”

Ziyu objected: "Impossible, the wells of the Tang Dynasty, only Zhuangzi has this kind of well, and they have all been changed?" ”

"Then what do you think he wants the well for?" Jin Ju asked Ziyu.

"Maybe it's a rich man who likes it and gets through ......"

"Shut up, Wei Shangshu is also something you can arrange?" Li Chengqi waited for Ziyu to take a look.

He continued to press, unable to figure out how to think about it.

"I wish I had asked Wei Shangshu." Li Chengqi let go.

At lunchtime, Li Yi appeared, and the kitchen stopped beating sauerkraut and white meat for lunch, and steaming them in a large steamer, instead of boiling and stewing.

Put the five-flowered three-layer meat at the bottom of each large box, add ginger slices and a few star anise, and the top is sauerkraut, pour water, cover and steam.

The steamed sauerkraut is not sour, and the soup is a clear soup, and the meat is not greasy at all, which is much more delicious than boiled.

Actually, the best soup is the refreshing, like a cold noodle soup in summer.

Soak it in the rice, although it is not good for the stomach, but it is enjoyable to eat.

Li Yi pretended to be a bowl and chose to eat steamed buns, if he was cooking, he would guarantee that he would make soup.

"Wei Zhigu, the secretary of the Ministry of Works, came over, dazzled, I tried two lenses for him." Li Chengqi, who chose the same food, said the situation.

"Is there anything wrong with your body?" Li Yi is very attentive to patients.

"Nothing. You said that when there is a drought, what is the difference between drilling an open well and the pressure well on your Zhuangzi? Li Chengqi finally asked the doubts in his heart.

"If you don't grab water, you can dig a diversion canal directly from the wellhead to other fields, and everyone takes turns pressing.

If it is replaced with an open well, it is natural that whoever catches the water will pick it up and pour it into the aqueduct.

Relatively speaking, pressure wells save energy, and the pressure well can generally hold two to three buckets of water from the time it takes to shake a bucket of water with a roller.

With orange trees, it is suitable for shallow wells, and when the water is deep, it needs to support a very high shelf. The pressure well is better to use at night and operate continuously. ”

Li Yi said to the eldest brother, it's as simple as that, and everyone is convenient to coordinate with the pressure well.

"Alas!" Li Chengqi sighed and drank the soup.

Jin Chrysanthemum and Ziyu lowered their heads and ate sauerkraut, without raising their heads.

"There are still capable people in the Ministry of Industry." Li Chengqi admits that the professional place is different, and he can actually think of such problems.

"The Ministry of Industry has been dealing with water conservancy for a long time, so it is natural to care about people's livelihood, otherwise what water conservancy projects will be built."

Li Yi thought of why the eldest brother sighed and said with a smile.

"What about the technology?" Li Chengqi thought that the people could have less trouble in grabbing water, and felt that it was indeed beneficial to the people.

"This technology is useless, the salt of Shu has always been better than the salt of the seaside, Shu salt is expensive and sea salt is cheap, Zhuangzi bought sea salt and then processed it himself.

The salt wells in Shudi, whether it is the gas that can be burned or the salt brine, are a big business to make money.

I have a method that can be used in drilling, small holes and deep wells.

The pressure well in Zhuangzi is dug out, and the pipe is buried later, because the water system around Chang'an is developed, so the groundwater layer is shallow.

Changing to another place is time-consuming and laborious. The salt of Shudi wells is all shallow wells, the kind with large mouths. ”

Li Yi hesitated and hesitated, and said a question.

"Brother Yi, you mean, you have a better way to dig a well, but this method can be used for well salt?" Li Chengji understood.

Then he hesitated, Shu Di was far away from Chang'an.

A good way to take it out, it is convenient to drill wells, and it is more convenient to mine well salt in Shudi, which is ...... Brother Yi can't make money.

Well after well, going deeper, it is easier to find water, salt brine, and gas.

Beat out the gas, ignite the boiling salt, beat out the brine, and be boiled.

Some are gas and halogen.

Every time it comes out, it's money.

With good well salt, you can buy things.

This technology ......

"Brother Yi, it's the kind that digs a big pit and then buries the pipe, don't drill deeper." Li Chengqi has decided, we can't suffer.

In the past, farm tools belonged to the people of the world who could use them, and they could dig wells, but they were not in charge of those places.

Yizhou Mansion, a good place, it's too difficult to get involved, well salt, Shu brocade, saltpeter, plus climate, Shu almost has everything you want.

Li Yi lowered his head to eat and ate very slowly.

He is weighing other technologies, and it is easy to say that the people in agriculture will do so as long as they have the conditions, increase grain production, and reduce labor intensity.

Drilling technology is also beneficial to the people.

Correct! Even if there is no drilling technology, digging wells is still a well in every village, and it takes some effort to dig it.

The most advantageous must be well salt, as long as it is taken out, it will not take long, and the well salt mining area in Sichuan will inevitably be a new well.

There is too much money, so much that I can't bear it.

It hurts to give it in vain, it hurts.

The people in the private room were all silent, even the palace maids and eunuchs understood the matter.

The proprietor actually has such a powerful thing in his hand, and there will be a large amount of Shu salt when he takes it out.

The Shu salt of the white flower flower eats the Shu salt without the bitter taste of sea salt.

Of course, no matter how delicious Shu salt is, it is still inferior to the salt on Zhuangzi.

But that's another matter, who can compare with Zhuangzi?

When the meal was finally finished, Li Yi put down his chopsticks and drank the last bite of soup.

said to Li Chengqi: "Big brother, how much power can we mobilize?" ”

Li Chengqi gritted his teeth and thought: "As long as you are willing to pay, it is very big." ”

"Can it be like heaven and earth? I want a profit, I really want it, not to keep it for anyone else. Li Yi felt that his mouth was a little dry, swallowed his saliva and said.

"Brother Yi is ......," Li Chengqi asked.

"Hmmm! I'm going to take 10 percent, half 10 percent, half percent, 1 twentieth. Li Yi lowered his requirements again.

The benefits are too great, they are moving, and they will die.

"Okay, for my brother to know what you mean, go and discuss for my brother." Li Chengqi thinks it's okay, yes, the third brother who pulls up the bright face, the emperor in the dark.

Our brothers share the money, but don't you want the money, third brother?

"But there's one thing that my brother has to talk about first." Li Yi stretched out a finger.
