Du Yuhan asked in confusion after hearing Uncle Liang's words: "Don't you have a water pump? It should be completely fine to use a diesel engine to drive the water pump."

Liang Shouzheng said: "There is no water pump or diesel engine. Laohewan Village doesn't even have a tractor, and the water pump is not even a turn for our village. Besides, there is no place to get so much diesel."

He Zhendong said: "Yes, it is difficult to get all oil and materials that are all combat preparations. It is even more difficult to get the tractor."

Du Yuhan thought for a while and said, "Since the machinery cannot be used, then use manpower and water trucks."

Several people looked at each other after hearing Du Yuhan's words.

Liang Shouzheng said: "Xiaohan, I have also heard of water trucks in some places. Can the water trucks you said work? Is it manpower?"

Du Yuhan nodded and said, "Just just a few people can operate it completely. If you set up a few water trucks by the river and dig a canal, we will not all irrigate the fields in our village, but most of them should be fine."

Liang Shouzheng couldn't help but sit up straight and said, "Xiaohan, if you can solve the problem of irrigating fields for our village, you will be the hero of our Laohewan Village. All the young and old in the village are grateful for you."

Du Yuhan smiled and said, "Uncle Liang, don't lift me so high. I just have an idea. Maybe it's OK. No need for the whole village to thank me. Then, just build a house for me in the village. I will pay for the money for building the house myself. You just need to approve me a piece of foundation and find someone to build it for me."

He Zhendong asked in confusion: "Xiaohan, why are you building a house in Laohewan Village?"

Du Yuhan said: "I like this place very much. In the future, when I graduate from medical school, I will go to the village to build a health center. I can treat the villagers and the surrounding villages can also benefit."

When Liang Shouzheng heard this, he became more energetic. He said excitedly: "Xiaohan, are you really going to go to the countryside to be a rural doctor and not stay in the city?"

Du Yuhan nodded and said, "Actually, I don't like the city at all. The countryside is relatively peaceful and free. I don't want to go to a hospital to work step by step. I want to be freer and more leisurely."

Liang Shouzheng said happily: "Then it's okay. I will build a house for you in my decision. Xiaohan, do you know how to do the water truck you mentioned?"

Du Yuhan nodded and said, "I will just draw the drawings and let my father do it. I have to find a few people to help him, because this water truck is quite large. You'd better organize people to dig a few water storage canals so that it's easy to water the land.

The geographical environment of Laohewan Village is very good. If you plan it carefully, do breeding and planting, it can be fully developed into a very wealthy village. Not to mention eating, it is okay to eat meat."

Liang Shouzheng was itchy after hearing Du Yuhan's words. He wanted Du Yuhan to draw the drawings of the water truck immediately and see if he could irrigate the fields.

Liang Shouzheng said: "Xiaohan, see when can you draw the drawings?"

Du Yuhan looked at Uncle Liang's eager anticipation and smiled, "You are really impatient. Do you have a quiet room? I need to think alone and don't disturb me. I will try to draw the drawings for you today. You have to prepare paper, pen and ruler for me, preferably one with scale."

Liang Shouzheng's family has people going to school, but there are paper and pen.

He drove his little daughter and son out of the room and asked Du Yuhan to draw drawings in the room where they just did their homework.

Du Yuhan needed a separate room and then took out information from the space to query.

Du Yuhan actually had this idea for a long time. She had already checked the information about the water truck and had designed the water truck, so she just took out the drawings and copied them.

Because of backward productivity, the country's level of mechanization in agriculture is quite low. To improve this situation, we must start with agricultural machinery.

Du Yuhan began to learn mechanical knowledge as early as when he had this consciousness.

She also obtained several degrees in her previous life. Although she had not studied mechanical design professionally, she still knew some knowledge about this.

She has also learned some knowledge of mechanical drawing, at least she can read the drawings.

In her life, she went to a bookstore to buy a few books on this aspect to study. However, there were very few books on this aspect to sell in the bookstore, and there were very few books on machinery in her space, so she could only learn the basics first.

Now she can at least draw some simple mechanical drawings. The drawings of the water truck are not very difficult, she can draw them completely.

Two hours later, Du Yuhan took the drawings he copied out of the room.

Liang Shouzheng immediately stood up and took the drawing handed over by Du Yuhan.

He Zhendong and Du Lianqiao also came over to see it.

Du Lianqiao has woodworking skills and can also look at the drawings. He can see the drawings of the water truck at a glance. Du Yuhan drew very clearly and marked with clear dimensions. Although it is a bit complicated to make, as long as the wheel axle and bracket are well prepared, everything else will be easy to deal with.

Liang Shouzheng handed the drawing to Du Lianqiao and asked, "How is it? Brother Du, can you do it?"

Du Lianqiao nodded and said, "It is difficult to do it, but it can also do it."

Du Yuhan said: "Make a few more such water trucks, put them by the river, dig a canal and lead them directly to the fields. The water flows directly into the fields. The two people in this water truck can control a car, and there is no need to waste so much manpower at all. The saved manpower can weed in the fields and do other work.

If the canal does not have so much time to dig, it will be shallower first, which can play a role in diversion. However, in order to achieve the future, we should still repair water conservancy and improve the farmland water conservancy facilities bit by bit. As long as the river water does not dry up, we will not be afraid of drought and we can have water to irrigate the farmland.

Our village should also dig some drainage canals. If the rain is heavy, you can use these canals to drain the water. This cannot be done overnight, so you can take it slowly. You should dig the drainage first."

Liang Shouzheng said: "I barely know how to dig this water canal. Why don't Xiaohan give us guidance?"

Du Yuhan said: "It's still so cold now, and the ground is so cold that it's still hard. It will take some time to dig the canal. I'll take a closer look for you after the New Year. Now you can make the water truck first."

Liang Shouzheng said, "You are right. I will convene a meeting of village cadres tomorrow to talk about the water truck. Then you will let your father be responsible for it. I will find a few people who are quick to help him. Then calculate centimeters for them."

It was almost dark as we talked about it.

When He Zhendong saw that he had to leave, otherwise it would be dark. It was difficult to walk on the road, so it would be better to go home before dark.
