After a while, the two arrived at the river.

I saw that the water truck more than 2 meter high was ready, and now I stood quietly by the river. This is a high-speed barrel truck. As long as the water truck is installed in a while, you can use the watering ground.

After Li Yu looked at the water truck, he asked, "How do you fix the water truck into the river?"

If the water truck is not installed and fixed well, it will not take long to use it, and it will collapse under the impact of water or strong wind. The water truck that has been hard-working and hard will be ruined.

As soon as Li Yu finished asking, a craftsman hurried over.

This person, Li Yu, knew him. He was the craftsman leader who had just been promoted by Li Xueyi, and was named Zhang Gong.

"Sir Li, look, this is the support of the water truck. The load-bearing capacity of this support is relatively large. In our plan, this support is to first find a few whole boulders weighing more than a few thousand kilograms, and then use eyelashes in the middle of the boulder, then nail some wood into the eye of the boulder, then punch these boulders, and install the stones with wooden stakes half buried on the edge of the river to fix them. Then fix the support of the water truck on these wooden stakes to make them firm and solid to achieve the function of supporting the entire water truck."

"Yes, your idea is very good, so that the water truck will not tilt or collapse in the future." Li Yu was very satisfied with the idea of ​​this craftsman after listening to the introduction of the craftsman.

"I will mention you a little bit, Xueyi, and I will immediately know how to install a fixed water truck. He is a very thoughtful person."

Li Xueyi was very happy to hear the praise of his craftsman from Li Yu's mouth. He was also very satisfied with his craftsman's performance today. He laughed happily: "Haha... you also feel that he is good, and I also think he has ideas."

Seeing Li Xueyi's proud look, Li Yu ignored him and understood his thoughts. Isn't he just always saying that his craftsman is stupid?

The farmers and tenants by the river had excited expressions on their faces, and they were eager to try, so they waited for a command to start installing and fixing the water truck.

During the waterwheel production in the past few days, these farmers and tenants who came to help finally know how amazing the big guy they helped to make is and how important it is to crops, which can directly affect their family's harvest.

After understanding this, they were more attentive to help make water trucks. After all, they no longer need to spend a lot of effort to water the ground manually. Moreover, if they can get a good harvest in autumn this year, it means that they don’t have to go hungry this winter! They can also have a full meal.

Food is the most important thing for people! No matter how big the big thing is, it is not that the point of being able to fill your stomach. What's more, with this water wheel, their crops can grow more vigorously and they can harvest more food in summer. As long as they know this, it's enough.

They have been used to good life in the past two years, but they did not expect that the Guanzhong drought this year and that the crops this year were about to be harvested. Unexpectedly, their boss solved this problem for them again.

If you are used to having a good life without worries about food and clothing, no one can stand it when they turn back and live a life of less food and no drink.

With everyone's concerted efforts and amid the slogans, the installation of the water truck was not long after the installation of the water truck was completed.

In order to install the water truck Li Yu, someone asked someone to make a simple lifting tool. In fact, it is a bit too exaggerated to say that it is a lifting tool. The structure is to borrow the principle of leverage and find a long wooden stick. A few ropes were tied to the short end to tie the components of the water truck. A large stone was tied to one end of the long end. In order to quickly install the components of the water truck without much effort.

The water truck is installed steadily in the water truck trough. The water truck trough is partially submerged in the river, and there are pedals on both sides. When used, one or more people step on the pedals, so that the gears drive the sink to rotate. The water tank in the water can bring the water up and then pour it into the drainage ditch and flow to the field.

Originally, Li Yu used a variety of gears when he designed it, and he was a little worried that the Tang Dynasty would not be able to produce qualified gears. Unexpectedly, these craftsmen actually made various gears with hardwood. Although it was not very standard enough, it was still completely useful when used on water wheels.

Li Xiuning saw Li Yu directing the craftsmen and farmers to install the water wheel, walked past and looked at him quietly, saying, "Can you lift the water to the shore in this way?"

Seeing that Li Xiuning was in a good mood today, Li Yu said quickly: "Of course, but this water truck can only be driven by human resources for the time being. Due to the severe drought this year, the water level has become shallower, and the water level is too smooth in this section of the river, otherwise the water truck will even save manpower, so now it has to be driven by human resources."

"I feel it's pretty good. At least I've solved the problem of watering. I have to take a good look at it to see if the first water truck you designed is as useful as a new plow." After Li Xiuning said that, she rolled her eyes on Li Yu, ignored him, and went to see the water truck nearby.

Listening to Li Xiuning's tone and rolling her eyes, it seems that she has dealt with her brother in her heart and has a lot of resentment towards her!

After Li Xiuning left, Li Er walked over and whispered in his ear: "Cui Jinfu is going to find you?"

"Oh! It turns out that you asked him to give his daughter to me as a concubine, right?!" Li Yu suddenly realized after hearing Li Er's words. He understood that it was the reason why Li Er put pressure on Cui Jinfu. Why did Cui Jinfu look so ugly when he said that he gave his daughter to me as a concubine, and it turned out that this was the case.

Li Er carefully whispered again: "Don't just tell my third sister that I arranged it. I'm afraid she will slapped my skin."

Li Yu looked at Li Er's formation today and understood his thoughts. Since he had a conflict with Li Yuanji, Li Er felt that he would definitely not surrender to his elder brother in the future, so he came to win over him again.

No matter what Li Er is thinking, he solved the troubles left by his predecessor, and whether he is willing or not, he has to bear his love.

Li Yu was silent for a moment, smiled faintly, and said, "I remember what you helped me. I can promise to do three things for you in the future. But the matter of earning the throne between you and the prince is for you and the prince. No matter who you help, your third sister, I will not be happy. I will not help with this."

Li Er immediately said: "Are there too few three things? You also know that my third sister will know about Cui Jinfu sooner or later."

Li Yu said with a meaningful tone: "Do you, King of Qin, need me to help me in general matters? Generally, there is a major crisis in the country or a matter of life that is at stake. I can help you. You will know how important my promise is in the future."

Li Er didn't feel very convinced of Li Yu's promise. He didn't take it seriously. He was just a concubine. He just gave Cui Jinfu a small promise with the identity of King Qin and gave him some convenience. He didn't pay any price. He could make Li Yu promise three things. Even if Li Yu couldn't do it, at least it would be good to make a heaven-level warrior owe him a favor.

What Li Er didn't know now was how great the three things Li Yu had for his promise were. In the future, he easily blocked the danger of destroying the country for him.

After solving Cui Zhimeng's affairs, Li Yu started to have a headache again. Cui Zhimeng's affairs will be a troublesome in the future. I don't know how to tell Li Fei'er when I go back, but Cui Zhimeng is also a good girl. She is obsessed with her predecessor. She has a quarrel with her family for breaking up the engagement and almost dies of illness...

But now is not the time to think about these private matters. The water truck has been installed. The excited Li Er ran up to perform the water truck starting ceremony.

Li Er and the craftsmen stood on the pedals on both sides. As the few people exerted force, the water truck began to rotate slowly. In the early stage, the water truck was running heavy, but after the water truck turned a few times, the water truck started to operate normally.

As the waterwheel rotates, the river water is also brought to a high place by the sink, and then it is poured into the ditch very smoothly and flows outward along the ditch. The sink leads the river water into the dug water collection puddle. The water in the water collection puddle continues to increase with the continuous injection of water sources. The water collection puddle is finally completely filled with the river water and begins to flow into the canal connecting the farmland.

At this time, all the craftsmen and farmers involved in the construction of the waterwheel were cheering excitedly.

Looking at this well-running human resources water truck, Li Yu felt proud. He used the water truck more than a thousand years later in the Tang Dynasty in advance. Later, the Chinese people took a big step forward in the era of waiting for the rain to have a meal.
