Datang: Showdown, your father and I are Li Shimin

Chapter 128
Li Ze immediately led the village chief and other people around Du Village to observe the terrain and draw a map.

The hills or plains, deep pits, sandy land, and rivers of the entire village were marked out in detail by Li Ze.

"Doctor Li, what is the purpose of drawing this map? I have lived in this village all my life, so I can say that I know the village well. If you have any questions about the terrain, you can ask me." Village head Du Mao scratched slightly. He looked at the map drawn by Li Ze and felt very confused.

Li Ze squatted down, spread the map flat in front of everyone, and drew his finger on the line symbolizing the river on the paper: "I want to build a waterwheel here."

"Water wheel?" Du Mao frowned slightly, and looked at Li Ze very puzzled.

Only then did everyone remember that when Li Ze was walking along the river just now, his eyes never left the river.

Li Ze pointed to a point on the river on the map and said immediately: "This is the closest to the farmland and the village, so building a windmill here can continuously irrigate the farmland and deliver water to the village. Using the rotation of the windmill By constructing a large gear mechanism and using water to push the water wheel, the water wheel drives the pestle rod or the stone mill, so that crops such as paper pulp, corn, and wheat ears can be ground without the use of human or animal power."

Li Ze simply drew a few gear mechanisms on the ground, but everyone looked at each other in blank dismay.

A few old farmers and scholars knew nothing about these things, so Li Ze had no choice but to say, "Anyway, as long as this thing is built, it won't need manpower or oxen and donkeys to push and pull it in the future."

"So I need a lot of wood to build a huge waterwheel here."

Liu Pei, who is a carpenter, stroked his gray beard, squinted his eyes slightly and conceived for a while.

After a while, Liu Pei suddenly opened his eyes, and saw his eyes shining brightly at Li Ze and exclaimed, "Ah! The old man didn't think of this!"

"Everyone, the river flows endlessly. If you build a wheel-shaped thing to stand on the river, it can be pushed through the river. As long as you install gears on the wheel, you can let the river pull the mill for people or oxen and donkeys. !”

"Ah! Ah! How did you think of this, Li Mingfu? As a carpenter, the old man didn't even think of using the river!"

The old man's face was flushed with excitement.

Seeing that someone finally understood him, Li Ze was overjoyed. It was much easier to talk to people who understood than to talk to people who were completely confused.

Fortunately, I took this old carpenter with me.

Immediately, Li Ze dipped in the ink, took out another piece of paper, drew an octagon and said: "Mr. Liu, please look at it. Use wood to splice it into an octagonal ring, and then place a wooden water bucket at each vertex, and open it at the top." When the river water flows into the trough, it will follow the river, always raising the drinking water in the trough, and placing a baffle on the top to overturn the river water at a higher level."

"Bringing the river water all the way to the fields by connecting bamboo poles, even in dry weather, there is no need for manpower irrigation. It can also store water in high places between the fields during wet seasons, and it can be completed by directly digging the mouth and releasing water when it is dry. Watering, like this, is Liu Gong sure that this method is feasible?"

Li Ze made three strokes, five and two, and then simply drew a waterwheel mechanism on the paper with a pen, while pointing to the location of the river and the field on the map.

After Liu Pei saw it, he nodded excitedly. Finally, the village chief Du Mao understood the reasoning and clapped his hands again and again.

At this time, Zhou Song frowned slightly, looked at Li Ze's drawings and said: "I have seen something similar to this in my hometown, but it is very small. Doctor Li said, I'm afraid it needs to be A very huge waterwheel, but the river in Ducun is not very fast, but very gentle. I am afraid that such a huge waterwheel cannot be driven by this river, right?"

Hearing Zhou Song's question, the excitement on Liu Pei's face dissipated instantly, and he said immediately: "Yes! This river is gentle, and the water flow is not fast. It is probably impossible to drive such a large waterwheel..."

"Closure!" Li Ze confidently pointed to the marked place: "Elevate this place and the sides of the river, leaving only a channel about the width of the waterwheel, and dig the downstream lower and deeper, and the water flow will naturally change." Big, if it is still difficult to drive, you can store water upstream and dig the dam when using the water truck. Will you be able to drive the water truck soon? Although the amount of work will be huge, it is a once-and-for-all method!

"Furthermore, the interception can be blocked by wooden doors, which open when in use and close when not in use. In fact, there is no need to move too much civil engineering."

Liu Pei stroked his beard again, staring at the map with a solemn expression.

Not long after, he nodded repeatedly at the village chief and others, and immediately cupped his hands at Li Ze and said, "I'm so stupid, I didn't think of this method!"

"Li Mingfu, let's continue!"

Li Ze nodded slightly, as long as there is someone in the crowd who understands what he means, communication will become very simple, because you don't have to worry about no one understanding the blueprints you publish.

For Li Ze, as long as there is something that does not consume human and animal power, there are too many things that can be done.

Even in later generations, in any field, there will be a large number of mechanisms for rotation.

If it is said that the large amount of power generation in later generations is boiling water in different ways, then it can also be said that all machines are turning wheels in different ways.

Then Li Ze drew a huge pounding pit and a long pestle; as well as a giant stone mill equipped with gears.

These things are all too familiar to farmers.

"Tsk, tsk, tsk... These things in Li Ming Mansion can be said to have saved a lot of manpower for Du Village!" Du Mao looked at the simple sketches drawn by Li Ze with great joy and was full of praise.

And the three scholars also looked at each other solemnly, feeling that all the books they had read these years seemed to be wasted.

What nonsense are the Four Books and Five Classics? They still don’t know anything about these things.

Naturally, the three of them became more curious about the young man in front of them who was much younger than themselves.

Li Zesui stood up, looked at the blueprint in his hand and said to several other carpenters and villagers: "Since everyone can roughly understand what I mean, it will be easy to handle. In this way, I can go to draw with peace of mind." If you come up with detailed drawings, then I will have to trouble the artisans a lot!"

"Why don't we start preparing the wood now? I will pay you for the construction of this large waterwheel."

Liu Pei and several farmers looked at each other, then quickly shook their heads and said: "No, no! This thing is closely related to us. It benefits every farmer. It's just wages. I'll prepare the materials and earn two dollars." In a few days, this waterwheel will be built!"
