As soon as the housekeeper got up to leave, Li Er strode in.

"Hahahaha, brother Xian, I haven't seen you for many days, I miss it very much, what are you busy with?"

As he spoke, he looked back at the departing butler, and when he heard what they had just said inside, he thought to himself in his heart.

What kind of watermill were they talking about?

Is it a vehicle in the water, and if it is a vehicle in the water, isn't it a boat?

It's just a boat, what are you doing with such a mysterious thing?

"Brother Xian, I came here today to see what you are busy with.

Hey, I just heard the housekeeper say that your Zhuangzi arranged a waterwheel, what does this waterwheel mean?

Could it be a boat in the water? ”

After all, when they were communicating with the virtuous brothers, Li Er felt that he had to have divergent thinking.

There's a lot of stuff that you have to follow his process.

"Brother Xian, if you use a boat, I will have a lot more.

I can arrange for someone to send it to you as much as you need, and I will have as much as you want. ”

Poof.

Standing beside Zhao Mu, Li Yue and the others laughed.

"Father, the waterwheel that Zhao Gongzi said is not a boat in the water, but a tool that can be irrigated.

The waterwheel is placed in the water, and the flow of the river pushes the waterwheel to rotate so that the water can be transported to high places.

With this waterwheel, it is more convenient for the people to get water for irrigation.

If my father wants to see it, I can take him over to see it. ”

As Li Er's intimate little padded jacket, Li Yue can see through his father's eyes that his father is thinking of stealing the fruits of Zhao Gongzi's labor again.

Since the father wants to see it, then if he is a daughter, he must also fulfill his father's wish!

"Well, that's not good, right?

This waterwheel must be very important in Zhaojiazhuang, but the relationship between us and us, I can go and see it.

Brother Xian, why don't you get busy here first, I'll go over with Yue'er to see, what is this waterwheel?

I've not heard of it. ”

Seeing him like this, Zhao Mu felt funny, he wanted to see it, why did he have to make so many excuses?

With a wave of his hand, Li Yue got up, took his father and eldest grandson and uncle out of the front hall, and went to Zhuangzi's river.

The river is about two miles away from their Zhaojiazhuang.

In the past, when people planted, they dug ditches directly and diverted water for irrigation.

This year, I also used this method to irrigate, but it didn't take long, and I just felt that the water level of the river had dropped significantly this year.

Trying to dig ditches for irrigation again obviously doesn't work.

Some of the people began to drive their wagons to the river to fetch water, and came to the fields and began to water them little by little.

When the housekeeper reported this matter to Zhao Mu, Zhao Mu began to gather all the carpenters in the entire Zhuangzi.

It took 10 days to build the first waterwheel of Zhuangzi.

When the waterwheel was assembled and put into the river, the waterwheel was slowly running with the current.

When the water-filled container is pushed to the top, the water falls on the side of the pipe and is transported through this pipe to the side ditch.

Through this ditch that extends in all directions, the grain of the entire Zhaojiazhuang can be irrigated.

It's just that this year, with the expansion of the land, there is some land on the beam, the position is a bit high, and it is impossible to get timely irrigation through the way of ditches.

Simply arrange for manual construction of elevated irrigation canals, so that the water needs to flow overhead.

In this way, it is more convenient to connect all the fields together.

At this time, at one end of the river, Zhuangzi's people were mixing bricks to drive the foundation.

The distance between the foundation and the foundation, about 5 meters, lays a bridge pier.

The entire elevated canal is about 2 and a half meters high, and the distance is calculated by a special person, all of them are installed, and fixed above.

Until when all the arrangements are completed, you can use the entire Zhaojiazhuang all the time.

Under the leadership of Li Yue, the group arrived at the river.

"Father, there's a watermill spinning in front of you."

Li Yue explained the operating principle of this waterwheel.

Li Er glanced at the waterwheel in front of him, not to mention, through the push of the water, the waterwheel was hung like a bucket around it, which was already filled with water, and kept lifting it high under the action of water.

Lift it up to a high place and it will fall onto the pipe that is placed in the rear.

The pipe at the rear will transport the water to the ground, so it is very convenient to irrigate without any operation.

Looking at this waterwheel, Li Er sighed again.

Why is it that every time I come to Zhuangzi, who is a virtuous brother, I come so timely?

It is said that if this virtuous brother is not the person of his destiny, and God came down to help him, Li Er will definitely not believe it.

It has only been more than half a year, and various benefits have been made one after another, making the hands that have been earned soft.

Speaking of himself, he still needs the next step of excavation, and Li Er feels that he has to come step by step.

"Yue'er, is this waterwheel easy to make?"

"Father, I think they are very simple to make, and the carpenters of Zhuangzi will make them, but at this price!"

The father and daughter also have to settle accounts, and now the Zhuangzi of Zhao Gongzi has become Zhao Gongzi's person.

Even if his father is a saint today, he has to think about Zhao Gongzi!

Ahem, ahem.

"Don't worry, daughter, is your father the kind of person who likes white prostitution?

The money that should be given still has to be given. ”

Li Er's heart was smiling, this trip to Zhaojiazhuang was really worth it.

Mo said that it was the entire Tang Dynasty, and around their Chang'an City, how many such fields were there, because of the lack of water, which led to a decrease in grain production.

Most of them are because the water rivers are nearby, but the rivers are below, and the fields are above, and they want to dig ditches for irrigation. But there is nothing to be done.

It is necessary to carry buckets of water in their hands to carry water for irrigation.

In this way, the speed of labor will be slow, and a lot of grain will not be irrigated in time, which will dry up and reduce production.

Now with this waterwheel, it seems that it is not complicated to manufacture, but it can be promoted throughout Datang.

Nowadays, the new plough cane, the new seeder, and now a waterwheel, this is simply a three-piece set of Datang agriculture.

With such means, it is difficult for my Datang to be rich or not.

"Butler, I am very satisfied with this waterwheel, and I will go to Zhuangzi later to talk to the virtuous brother about the purchase.

How do you feel about this watermill in your opinion? ”

"The shopkeeper's waterwheel is simply my big means, if it is in my Datang villages, you can arrange a waterwheel close to the water source, this crop irrigation will be more convenient, wonderful, wonderful."

"Hahaha, actually, that's what I thought."

But what is the kind of elevated aqueduct that this virtuous brother is talking about, could it be that it is these in front of you?

Seeing the strange thing in front of him, Li Er showed doubts.

"Yes father, these are the elevated canals you see in front of you.

Zhao Gongzi said that this viaduct is something to be laid above our heads to take water for irrigation.

Because the aqueduct laid is to be above our heads, it is also called an elevated aqueduct. ”

The elevated canal, the canal hanging overhead, Li Eryi listened to it,

Seeing these things, several people said as they hurried to the way back.

On the way back, I saw people building there.

Li Er was interested, and rushed straight over.

Seeing the thing in front of him that he had never seen before, Li Er stepped forward, touched it with his hand, and knocked it gently, not to mention, this thing is quite sturdy.

"Yue'er, what is this, why have I never seen it?"

Li Yue smiled awkwardly.

"Father, I don't know how this thing is made, if you want to know, you have to ask the housekeeper."

Seeing the butler in front of me, Li Er strode forward.

"Butler, you're here."

"Shopkeeper Li!"

"I said, butler, I think you're going to need to have these things dragged up.

I've just finished watching the waterwheel.

If you want me to say, you might as well just build a high canal, so that there is no need to drag it like this.

When the time comes, there will be another door in the middle of the canal, which can be used for the big guys to travel. ”

The butler shook his head after hearing this!

"Shopkeeper Li, we thought the same way at that time.

But my young master said that it was too hard to do that, and we didn't build the Great Wall, so why did we do so much?

Besides, if all the roads were blocked, it would be time and effort for the people to walk.

That's why we built this set of equipment to frame it! ”

Come on, come on, 1, 2, 1, 2.

"Looks like this thing is heavy, isn't it?"

"Yes, it's quite heavy when it's in transit.

We arranged a large number of people to transport it from Zhuangzi little by little.

But it's not a lot of effort to build it up. ”

Li Er looked up, just a few wooden shelves behind it, with a piece of wood in the middle, you tell me that it is effortless to fool people?

"Back to the shopkeeper Li, the young master said that this is called the leverage theorem.

If it is a fulcrum for my young master, even the whole earth can be pried up! ”

Earth?

"Father, the housekeeper means that he can lift objects that are several times heavier than this, dozens of times!"

"Oh, Brother Xian is really a man of God, and he is also amazingly powerful."

I really didn't expect the virtuous brother to be born with divine power.

"Forehead, father, this thing is called science, if you don't believe it, your father can easily lift it down in the past!"

"Oh, really?"

Speaking of this, Li Er was interested, and stepped forward to look at the thing in front of him.

took it in the hands of the personnel on the side, and dragged it gently, but I didn't expect to be lifted up by myself, but I didn't have to make any effort.

Is this the legend that gives yourself a lever and you can pry the earth?

Wonderful, wonderful, hahahaha.

Coming here today not only got a waterwheel, but also learned a lever to pry the earth, Li Er was very happy.

Today, I only sighed, and I sighed again when I saw this thing in front of me.

"Presumably, after this elevated canal is erected, the water will be brought in, and this elevated water can be used for several years!"

"Shopkeeper Li, my young master said that if this elevated canal is laid, it can be used for 1,000 years, or even longer.

Even ordinary people can't destroy it if they want to, unless they encounter a natural disaster.

Otherwise, they will be fixed to it, not afraid of the wind and the sun. ”

What?

Li Er's eyes widened, and he looked at the housekeeper with unconvinced eyes.

Are you kidding me?

Although he hadn't seen this thing, Li Erke saw the pier of the frame below.

The brick construction used everywhere in Datang is used, not to mention other places.

Even if it is the city of Chang'an City, I dare not say that it can be exposed to wind and rain and will not be repaired for 1,000 years.

Is it possible that this thing will become a god, and if it is not repaired, it will not be afraid of destruction?

"If Shopkeeper Li doesn't believe it, there is a stone next to it, you can test it yourself.

Smash a stone hard at it and see if you can destroy it! ”

If it was usual, I just laughed it off, but this time, I really didn't believe it.

Li Er stepped forward and prepared to lift a stone, but the stone was a bit heavy, and the housekeeper arranged for two people to go over and lift the stone instead of Li Er, and walked in front of him, smashing the ditch that had not yet been lifted up.

The moment the stone fell on it, nothing happened to the ditch.

Li Er stepped forward to take a quick look, except for a small mark that appeared on it, there was really nothing on it?

This, this, how is this possible?

"I said, butler, this is amazing, what the hell is going on?

What are you making of this ditch? ”

Hahahaha, this time the surrounding people also laughed.

In fact, what happened today seemed to be familiar to them that day, and the big guys didn't believe that this thing was invulnerable at the time, until it was made and tested in person, and my good boy was simply a god.

The young master is really powerful.

"Shopkeeper Li, the name of this thing is reinforced concrete."
