Looking at the children's greedy eating, Lu Shi and Zhao Dahai drank and chatted while picking up some wild vegetables to drink, of course, the topic also changed from aimless to the current drought and can't farm.

Once it comes to the world under this natural and man-made disaster, Zhang Laoshi only has a long sigh left, and he no longer has the slightest intention of drinking.

This is all spring ploughing is imminent, this sky is still clear, not even a little rain meaning, seeing that there is no harvest in the field, and these little tigers of their own family are going to eat and drink, I really don't know what to do in the future, if it continues like this, I am afraid that even the wild vegetables will not be able to help, and what is worse is that the government taxes have to be paid, or they will not be able to pass the level of the cool officials, that is, the little ghost of the king of Hades, the family is ruined.

Speaking of this topic, Zhao Dahai lost his interest in drinking, and fed his goddaughter to eat, and he lost his heroic mood.

Lu Shi saw it, and sincerely grieved for the small people in this world, since he decided to stay and do something, in order to thank the Zhang family for a meal, what should he do to change all this, but it is a difficult problem to really want to change the situation of the Zhang family, how can manpower win the sky? So Lu Shi searched his stomach and thought about his own common sense in later generations, to see which object in his memory could solve this urgent need, and after thinking for a long time, he suddenly remembered a water conservancy weapon, and his heart couldn't help but be enlightened.

The sharp weapon is not complicated, think about the details, it is also what you can do, thinking of this, Lu Shi put down the wine bowl, and said with a faint smile: "Two brothers, this day is not a big drought, but it is not a drop of rain, I see that the water in the Shajia River in front of the village is still abundant, but now the fields are on the river embankment, there is no irrigation, and it is impossible to cultivate and plant, isn't it?" ”

Zhang Laoshi saw that Lu Shi was right, nodded helplessly: "I also let the master know that the river water in the world is drought, and the embankment is higher, that is, a strong man carries water to water the ground, and he can only have one or two loads of water at the end of the day, and he will dry up immediately when he pours it into the ground. Then there was another long sigh.

"Not to mention a small household like me, that is, a large household like the Zhang family, who paid money and grain to hire long-term and short-term workers to drive out the tenants only worked for a few days, and then gave up helplessly, because even if it was planted, it was not enough to spend these days, and I could only watch the crops die of drought, and the farmers were counting on the production of this field, but now it is good, everything is hopeless, and now our brothers are here to eat and drink, saying that they have to go out for a few days to bring their families and become homeless, just like around Yulin, or starve to death, Either they are forced to die by the officials, and there is no other way out than to be a homeless person who does not know which ravine they died in? ”

After that, they drank the wine in the bowl sullenly, the children did not understand the difficulties, and still happily grabbed the meat and vegetables, but at this time, there was a suppressed cry from the Zhang family's mother-in-law in the inner room.

However, Lu Shizhan smiled and said: "Brother, don't worry, the younger brother has a way, not by artificial, you can let the river water go up to the terrace by itself, and water this field day and night." ”

As soon as these words came out, Zhang Laoshi's eyes lit up at that time, and he hurriedly stepped forward and asked excitedly: "Brother, are you joking?" And is it a good thing that you don't need manpower to let the river go up to a plateau of more than ten zhang by itself? It's a lifesaver. After saying that, he sighed when he thought about it blankly, and then his expression darkened, and he shook his head and said, "Unless you are an immortal, where can you still have such a ability?" The brother laughed. ”

"Brother, don't believe it, in fact, my method is also simple, I just need a few carpenters." Lu Shi said confidently.

Zhang honestly saw that Lu Shi was serious, and he had hope again, so he hurriedly said: "It's not difficult to find this carpenter, brother, I am the craftsman, the carpenter in the craftsman's household, in this piece, my brother said that he can't do it, I dare to say, no one can make it anymore." When he said this, his originally rickety waist was proudly straight.

San'er jumped out and said loudly: "I know that the master is a capable person, or he can't make such a good bow and arrow, there must be a way to make a way to let the river water go to the stage by itself." ”

The best thing to fool and worship is the child, a bow and arrow that surpasses modern times, and turns Lu Shi into a god in San'er's heart. Of course, the premise is that San'er is a bow and arrow, knowing the huge difference during this period, if Lu Shi shows this bow to a cook, the cook must praise loudly - good, good, good burning stick.

Blind worship kills people, these three have become loyal fans of Lu Shi, and he firmly believes that as long as Lu Shi says, it will definitely be done.

San'er chattered about the longbow with Zhao Dahai, and 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 disbelief.

"It's true."

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

"Since my brother has good craftsmanship, and my brother has a good way, the mountains are full of big trees, and now the land can't be planted, and being idle is idle, it's better to try it according to my brother's wishes, it doesn't hurt if it doesn't work, it's better than not expecting it, isn't it? I'll do it tomorrow, I'll give my brother a shot. Zhao Dahai said with confidence.

Zhang honestly smiled; "Brothers, tomorrow, we'll try Brother Lu's method." This is also the tone of a dead horse as a live horse doctor, in fact, he just doesn't want to hurt Lu Shi's heart.

In fact, Lu Shi is now a bamboo in his chest, you let Lu Shi now open the golden finger of the whole water pump out, that is unrealistic, it takes a lot of supporting facilities to complete, but the whole windmill is easy.

Yes, where is the Dutch windmill that has the existing human-powered pedal water wheel in this era?

In fact, there are two technical things that do not appear in China, but it is these two things that play a very important role in the development and promotion of society, one is the four-wheeled carriage.

The four-wheeled carriage has a greater advantage over the two-wheeled carriage, because the weight of the goods on the four wheels is on the car, and the horse only plays the role of pulling, which saves the pressure of the horse's wheel, so the four-wheeled carriage is often about twice the capacity of the two-wheeled carriage, (the two-wheeled carriage can load two to three thousand catties,) but because the ancient Chinese did not solve the very simple problem of front-wheel steering, it failed to develop. Until the end of the Qing Dynasty, foreign envoys brought four-wheeled carriages, and everyone was still waiting to see the jokes, and the heart said, see how you turn, and don't go directly into the ditch.

Another key technology is the windmill represented by the Netherlands.

Because of the low-lying terrain, the Netherlands always faced the erosion of the sea tide, and the instinct to survive gave the Dutch the motivation to build dams and embankments, compete for land to the sea, and create a 9-meter-high pumping windmill to create a living home. In 1229, the Dutch invented the world's first windmill to power humans.

For a long time, people used primitive methods to process and mill grains, first by hand, then by horse-drawn treadmills and waterwheels propelled by water, and then by windmills. Because the Netherlands was flat and windy, windmills quickly became popular. The rapid increase in demand has led to the transformation of windmill technology.

The use of windmills was no longer limited to grinding grain, but developed into processing barley, sawing logs into trusses and planks, making paper, extracting oil from various oil crops such as flaxseed and rapeseed, and grinding spices to make mustard.

Despite its many uses, people prefer to remember the old European saying: "God created man, and the Dutch windmill created the land." ”

Indeed, without these towering pumping windmills, the Netherlands would not have been able to acquire nearly a third of its land from the sea, and would not have had the aromas of cheese and tulips that followed. So the windmill is a very important technology.

Shaanxi is located on the edge of the Mongolian steppe and has always been very windy, making it an ideal place to build windmills. Therefore, Lu Shi is going to build a windmill on the platform to lift water, of course, in the future, he may develop grinding grains at the same time, sawing logs into trusses and planks, extracting oil from various oil crops, and ----- and other uses, bringing some income to the Zhang family, but now I want to do it, but there is a bit of a lewd tendency, technology is one thing, but manpower, material resources and the environment are the conditions for the survival and development of technology.

Let's start with the windmill carrying water.

In fact, the production of windmills is very simple, as long as you understand the principle, you can do it with the stupidest carpenter, of course, this is a small windmill, if it is large, then it will take many people to cooperate, but now Zhang Laoshi and his children, these manpower is enough.

Imagine the windmills stretching out their long wind arms instead of manpower to lift the river water to the terrace day and night, irrigate the cracked land, let the wheat thrive, and let the Zhang family have no worries about food and clothing, what an exciting prospect it is.

Lu Shi excitedly said his designs and ideas, and took the trouble to explain the key points during the period. Zhao Dahai didn't know what to do, but Zhang Laoshi, who was a carpenter, was already stunned, and he had no doubts about Lu Shi's proposal.

A simple, manpowerless machine can change the irrigation process of his own land, imagining that beautiful prospect, the room full of people except Lu Shi and the naïve little girl, can there be any other expressions left to be stunned?

Zhang Laoshi couldn't sit still anymore, and said eagerly: "Since the master has such a good thing, why don't we do it right away?" ”

Honestly smiled and stood up and said, "Exactly, let's start doing it now." ”
