Seeing the children's greedy eating behavior, Lu Shi and Zhao Dahai were drinking and chatting while picking up some wild vegetables to drink. Of course, the topic also changed from aimlessness to the point where the drought is now uncultivated.

Once he talked about the world under the natural disaster, Zhang Laoshi was left with a burst of sighs and no longer had the intention of drinking.

This is all the impending spring plowing. The sky is still clear and there is no sign of rain. It is obvious that the fields are gone, but the little tigers in their homes want to eat and drink. I really don’t know what to do in the future. If this continues, I’m afraid I can’t even provide wild vegetables. What’s even more fatal is that the government has to pay taxes, otherwise I can’t pass the quarrel of the cruel official, that is, the king of hell, the family is destroyed and the people are killed.

Speaking of this topic, Zhao Dahai lost interest in drinking, and fed his goddaughter to eat, and he no longer had a heroic mood.

When Lu Shi saw this, he was sincerely sad for the common people in this world. Since he decided to stay and do something to thank the Zhang family for their gratitude, he should always do something to change all this. But really wanting to change the situation of the Zhang family is a difficult problem. How can human power surpass nature? So Lu Shi scrambled his mind to think about his common sense in the future and saw which object in his memory could solve this urgent problem. After thinking for a long time, he suddenly remembered a water conservancy tool, and his heart suddenly became clear.

The weapon is not complicated. Thinking about the details, I can do it myself. Thinking of this, Lu Shi put down the wine bowl and smiled faintly: "Two brothers, this world is drought, but it is not raining. I see that the water in Shajia River in front of the village is still abundant, but now the fields are all on the river bank, and they cannot be irrigated and planted. Is that true?"

Seeing that Lu Shi was right, Zhang nodded helplessly and said, "I still told the master that the river water in the world has dropped and the embankment has increased. Even if a strong man is carrying water to irrigate the land, he can only work one or two tirings in a day. He will immediately do it when he waters it into the ground. Even if he works hard, he will not be able to water it again in the future. He will only die of drought and waste seeds in vain." After saying that, he sighed again.

"Don't mention small households like me, even big households like Zhang's family, who have been paying off money, grain, and hiring long-term workers to drive out tenants for only a few days, they had no choice but to give up because even if they were planted, the harvest was not enough for the past few days of expenses. They could only watch the crops die of drought. The farmers were counting on the land for the land. Now, everything was hopeless. Now our brothers are eating and drinking here, and they have to take a few days to become refugees, just like the surrounding areas of Yulin, either starving to death or being forced to death by the official family. Is there any other way out except being a refugee who doesn't know where to die in?"

After saying that, he drank the wine in the bowl in a depressed manner. The children did not understand the difficulties and were still scrambling to eat carnivore. At this time, the depressed cry of Zhang Jiapo came from the inner room.

However, Lu Shizhan smiled and said, "Brother, don't worry. I have a way. Don't use manual labor, so that the river can go to the platform by itself and water the soil day and night."

As soon as these words came out, Zhang Laoshi's eyes lit up, and he hurriedly stood up and asked excitedly: "Brother, are you talking about joking? You can also let the river reach a platform of more than ten meters without manpower? This is a save everyone." After saying that, he thought blankly but sighed, and then his expression dimmed, and he shook his head and said: "Unless the gods, how can you have such ability? Brothers are joking."

"Brother, don't believe it. In fact, my solution is simple, it just needs a few carpenters." Lu Shi said confidently.

Seeing that Lu Shi was serious and had hope, Zhang Laoshi quickly said, "It's not difficult to find this carpenter. Brother, I am a craftsman, a carpenter among the craftsmen. In this area, the brother said that he couldn't do it. I dare say that no one could do it anymore." When he said this, his originally hunched waist was proudly straight.

San'er even jumped out and shouted: "I know that the master is a capable man, otherwise he would not be able to make such a good bow and arrow. There must be a way to make the river water go to the stage by himself."

The best thing to fool and best worship is the child. A bow and arrow that is more than modern times will turn Lu Shi into a god in Saner's heart. Of course, the premise is that Saner is a bow and arrow, and knows the huge difference during this period. If Lu Shi showed this bow to a chef, the chef would definitely exclaim loudly - OK, OK, good fire stick.

Blind worship kills people. These three have become Lu Shizhong's loyal fans. He firmly believes that as long as Lu Shi says, it will definitely succeed.

San'er chattered about the longbow and Zhao Dahai. Zhao Dahai was also a military family. Of course, he knew the huge gap between this bow and the current bow and arrow, and looked at Zhang Laoshi with unbelievable eyes.

"This is true."

One sentence, the honest man's sentence established Lu Shi's position as a capable man in Zhao Dahai's heart.

"Since my brother has good skills and brothers have good solutions. The mountains are full of big trees. Now I can't plant the land. I'm idle. It's better to try it according to my brother's wishes. It doesn't matter if I don't succeed. It's better than not expecting it, right? Let's do it tomorrow, I'll fight my brother." Zhao Dahai said with confidence.

Zhang Laoshi smiled with no choice but to laugh, "Brothers, tomorrow, we will try Brother Lu's method." This is also a tone of using a dead horse as a living horse. In fact, he doesn't want to hurt Lu Shi's heart.

In fact, Lu Shi is now confident. If you let Lu Shi open his golden finger and pump out the entire water pump, it is unrealistic. It requires a lot of supporting facilities to complete, but the entire windmill is easy.

Yes, where is the current human-powered waterwheel in this era where the economic speed of Dutch windmills come from?

In fact, there are two skills in China that have not appeared in China, but these two things play a very important role in the development and promotion of society. One is a four-wheeled carriage.

Four-wheeled carriages have greater advantages over two-wheeled carriages, because the weight of the carriage on the four-wheeled carriages is on the carriage, and the horse only plays a pulling role, which saves the pressure of the horse's shaft. Therefore, four-wheeled carriages are often about twice the capacity of two-wheeled carriages (two-wheeled carriages can load two to three thousand kilograms, but because ancient Chinese people did not solve the simple front-wheeled steering problem, they could not develop. Until the end of the Qing Dynasty, foreign ministers brought four-wheeled carriages, everyone was still waiting to see a joke, thinking, seeing how you turn, you won't go directly into the ditch.

Another key technology is the windmill represented by the Netherlands.

Because of the low terrain, the Netherlands always faces the erosion of sea tides. The instinct of survival gave the Dutch motivation. They built dams and embankments, fought for land towards the sea, and created pumped windmills up to 9 meters high, creating a home for living. In 12 years, the Dutch invented the world's first windmill that powers humans.

During a long period, people used the original method to process the grinding grains. They were initially manual operation, then horse-drawn treadmills and water-driven water wheels, and then windmills that operated by wind. Because the Netherlands is flat and windy, windmills were quickly popularized. The rapid increase in demand has led to the transformation of windmill technology.

The use of windmills is no longer limited to grinding grains, but has developed into processing barley, sawing logs into stringers and wooden boards, making paper, and pressing oil from various oil crops such as flaxseed and rapeseed, and grinding spices into mustard.

Despite its many uses, people are more willing to remember this saying that was circulated in Europe in the past: "God created man, and Dutch windmills created land."

Indeed, without these towering pumping windmills, the Netherlands would not be able to obtain nearly one-third of the land from the sea, and there would be no subsequent aroma of cheese and tulips. Therefore, windmills are a very important technology.

Shaanxi is located on the edge of the Mongolian grasslands. It has always been very windy, which is an ideal place to build windmills. So Lu Shi is planning to build windmills on the platform to lift water. Of course, in the future, it may develop grinding grains, sawing logs into trusses and wooden boards, and squeezing oil from various oil crops. It also brings some income to the Zhang family. But now I want to do it, but I have a bit of a fantasy tendency. Having technology is one aspect, but manpower, material resources and environment are all conditions for technology to survive and develop. Now I am just looking for death.

Let’s start with the windmill to lift water.

In fact, the production of windmills is very simple. As long as you understand the principles, you can do it by just a stupid carpenter. Of course, this is a smaller windmill. If it is a big one, there will be more people working together. But now Zhang Houshi and his children have enough people.

Imagine windmills stretching their long wind arms instead of manpower to bring the river water to the platform day and night, irrigating the cracked land, allowing the wheat to grow healthily, and allowing the Zhang family to have food and clothing without worries. What an exciting prospect.

Lu Shi excitedly expressed his design and ideas, and he explained the key points untiringly. Zhao Dahai didn't know what to say, but Zhang Laoshi, as a carpenter, was already stunned and had no doubt about Lu Shi's proposal.

A simple, without human resources, can change the irrigation process of your own land and imagine the beautiful prospects. Apart from Lu Shi and the innocent little girl, can there be other expressions left in the room besides Lu Shi and the innocent little girl?

Zhang Laoshi could no longer sit still and said anxiously: "Since the master has such a good thing, why don't we do it right now?"

He stood up with a honest smile and said, "That's right, let's start now."
