Chapter 55 Lessons in the Water Conservancy School

Zhu Qizhen told Yu Qian some things about water control, called Wang Zhen, and ordered Yu Qian to transport three million taels of silver from the inner treasury to Yu Qian, so that he could rest for a day, and then go back tomorrow to prepare to repair the embankment in the more dangerous part of the local area.

Then Zhu Qizhen left Ruan An and Mu Jing behind.

Zhu Qizhen said: "Do you have any bottom in your heart about teaching water conservancy? ”

Ruan An and Mu Jing are both old people in the palace, so they can naturally hear Zhu Qizhen's voice. Mu Jing immediately said: "The slave is ignorant, please give your majesty advice." ”

Zhu Qizhen nodded with satisfaction and said, "I think that the matter of water conservancy is the most important. If you want to do a good job, you must do it carefully, as long as you do it carefully, you can do it well. ”

"Between me, the current strategy for controlling the water is full of assumptions, and I didn't think about detailed calculations at all."

Ruan An stammered a little for a while, and said, "Calculation? ”

A lot of times in antiquity was empirical science. It is also intuitive to feel how to control water. This is also why Zhu Qi put on a model and persuaded the Manchu ministers.

It is because these are in line with the thinking habits of the Manchu ministers.

In the calculation of water control, probably the most is the calculation of the engineering quantity, the calculation of earthwork and stonework, and the calculation of the sectional guard.

There's not much more.

Zhu Qizhen said: "Yes, first set weights and measures to create a ruler, one foot to set the square, and then set the cubic liter, and calculate the amount of water by how much water is in one liter." I want all the movement of water to be expressed in numbers. ”

Ruan An and Mu Jing are even more like reading a book from heaven.

Zhu Qizhen said: "I remember that there are sheep and horses on the Yellow River, that is, they take a sheepskin raft down the river and report the flood peak downstream, which is the speed of the flood peak. And the amount of water. ”

Zhu Qizhen saw that they still didn't understand.

Impatiently, they were given a math lesson, calculating the sediment content, runoff and other things explained 1510.

In fact, Zhu Qizhen doesn't know how to control water, but he knows that mathematics is the mother of science. If there is a genius in the water conservancy school, he can use a mathematical model to explain all the changes in water flow on the Hebei Plain.

Is Hebei Water Conservancy still afraid that it will not be cured?

With such a successful experience, Zhu Qizhen will naturally want to promote it in other aspects.

It's just that Zhu Qizhen looked between the eyes of the two people below, and there were vaguely countless reasons flying by, and he knew these things, and he couldn't say it very clearly.

Zhu Qizhen sighed and said secretly: "Let's go, I'll keep an eye on this matter more." Then he said: "The water conservancy school must open arithmetic, and now it is the main course, in addition, there is also the beginning of drawing, I don't know the geographical advantages, how to govern, but also have experiments, which is the strategy of harnessing water and attacking sand."

Before the experiment, who knows right or wrong. ”

"That's why I set up the water conservancy school on the bank of the Lugou River, and we have to divert water."

"In addition, it is necessary to set up machinery, that is, water conservancy machinery. Such as water wheels, after all, the drought in the north is serious, sometimes the water level is very low, and it is impossible to release it at all, so you can only find a way to lift water, and use water wheels, which is naturally the most convenient thing. ”

Zhu Qizhen couldn't remember what to say for a while, and waved his hand and said: "Arithmetic, drawing, experiment, and mechanical, these four courses are all very important, and even indispensable, you look at it and add it, in short, Ruan An, Mu Jing, as long as you two do it well, you will have a name behind you." ”

"Think about it, in the future, the ministers of the Great Meiji Water Department will be your disciples and grandchildren, are you afraid that you will not have a reputation?"

Ruan An and Mu Jing were excited and at a loss, excited that Zhu Qizhen painted a picture cake for him, they were all eunuchs, so naturally they would not have a good reputation.

But now this one thing can guarantee their posthumous name. They were naturally very excited and excited, but in the face of what Zhu Qizhen said, they didn't know what to do at all?

What is the sediment content, runoff, what are the concepts?

They didn't understand, but they didn't dare to go back and ask Zhu Qizhen. I can only think about it secretly.

When the two of them left the Qianqing Palace, Ruan An said, "Senior Mu, let's find a place to ponder." ”

Mu Jing said: "Okay, I will also call my righteous sons, young people have bright brains, maybe they can think of something." ”

When the two racked their brains for the task assigned by Zhu Qizhen.

Zhu Qizhen had just had lunch and met Li Shimian again.

Li Shimian has been in Beijing for a few days, but he still hasn't slowed down.

Zhu Qizhen felt a little unbearable when he saw this old minister like this, but he remembered the disaster in the north and the more than one million stone of grain that had just been reduced.

Zhu Qizhen could only harden his heart and said to Li Shimian: "Now there is a shortage of food, although four million stone grains have come one after another. But I'm afraid it's not enough. I want Qing to bring the silver and go to Guangdong or Jiangnan again, in short, find a way to bring another batch of grain to Beijing. ”

Li Shimian's face was embarrassed.

Zhu Qizhen was not good at giving a strong order, and said: "If Mr. is unwilling to go, Mr. will recommend one person to go to the south on behalf of Mr. ”

Li Shimian listened and was a little angry. said: "Your Majesty is suspicious, is he greedy for life and afraid of death?" Since Chen Shufa read, he has known that Kong said that Chengren and Meng said that he took righteousness. The minister is not afraid of death, besides, although the old minister is old, but he can still eclipse the rice, it is when the old man is strong, the reason why the minister hesitates is not that the minister is unwilling to be used by His Majesty. It's this one thing, it's very difficult to do. ”

Zhu Qizhen said: "But I don't know where it is difficult? ”

Li Shimian said: "First of all

There are no more ships in Guangzhou. ”

Zhu Qizhen was taken aback and said, "How is it possible? ”

Li Shimian said: "The minister has already brought all the ships that Guangzhou can bring over. ”

Zhu Qizhen said: "So, you just take the ship from Tianjin and go back?" After Zhu Qizhen said this, he immediately knew that it was inappropriate.

Because what he remembered was none other than the monsoon.

Li Shimian sighed and said, "Your Majesty doesn't know anything. Although the hard sails of our dynasty are good at using the wind in all directions, the headwind is still southward, and now is the time when the south wind is strong, and even many shipowners who stay in Tianjin will go south when the north rises again in autumn. ”

"Even if the headwind can sail, it is quite slow, and the minister is worried that the grain will be transported in the autumn this time."

"But in the summer and autumn season, the sea is constantly windy, and no matter how big the ship is, there is only one dead end, and the southeast coast is a piece, appearing from time to time."

"The minister is worried that something has gone wrong with this silver at sea."

There are some things that Li Shimian didn't say.

For example, these shipowners seem to work for the imperial court, but if they really think that they are good men and women, it is a big mistake.

Needless to say from Zhu Qizhen, Li Shimian estimated that Zhu Qizhen would have to shake at least two or three million taels of silver, because without this amount of silver, he would not be able to buy enough grain.

After all, after Li Shimian's large-scale purchase in Nanyang, it is no wonder that grain prices in various places have not risen.

With so much silver on the ship, and going to sea with so many owners, it was a test of their self-control. Even if it was a million taels of silver, it was money they had never seen in their lives.

And Li Shimian was still a little worried, and said: "The minister is worried, there is no food in Nanyang." ”

Zhu Qizhen listened, and said with some doubts: "How come, Nanyang is not summerless all year round, three crops a year, from the time Mr. went south to now, it is estimated that the new season of rice in Nanyang will be ripe again." How can there be a shortage of food? ”

Li Shimian listened to Zhu Qizhen's words, and said with some tears and laughter: "Your Majesty thinks Nanyang is like this? Yes, although the climate of Nanyang is unique, rice is harvested three times a year, but the people do not have the right to be independent, only the head of the people's orders is to listen, and the laziness is extreme, although the climate is good, but people want to get something for nothing, but it is impossible. ”

"Before the minister, the Nanyang rice has been almost harvested, and Your Majesty can see that only Annan is the remnant of our dynasty, and the grain savings are the most. As for the rest of the countries. Li Shimian didn't say much, just sneered twice.

Zhu Qizhen was annoyed in his heart. I thought I was bad. Think about it, in ancient agricultural societies, food production was national strength.

And Annan's reputation as a small overlord in the South Seas for so many years doesn't this show one thing, that is, Annan's grain production is the highest?
