Defeat natural disasters with farming

Ye Yu had just stopped writing when he saw Chu Xufeng coming out of the room through the window that was opened at one corner. Although his expression did not change, he was still calm, but Ye Yu knew that he must be in a bad mood right now. ,because...

Ye Yu looked at Chu Xufeng's left hand behind his back. After getting along for such a long time, he can be sure that he is the person who knows Chu Xufeng the best. He probably doesn't even understand his father. As long as he sees Chu Xufeng put his left hand behind his back, It means he is worried about something.

Thinking of this, Ye Yu stood up and stretched. Just as he pushed the window completely open, a gust of cold wind swept over him. He shrank his neck and waved to Chu Xufeng who was looking over, "Come on."

Chu Xufeng's expression suddenly relaxed, and he walked in with a cold wind.

At this time, the tea in the room was just boiling, and Ye Yu poured two cups of Pu'er tea on the table, warming his hands while asking doubtfully, "What happened?"

Chu Xufeng was silent for a while, until the rising white air disappeared, then he took out a letter from his sleeve and handed it to Ye Yu.

After Ye Yu took it, he took a look at the envelope. It was very simple, with only a few words written on it. My son Baojin personally opened it. It seemed that it was written to him by General Chu.

Chu Xufeng signaled him to open it.

Now that he got permission, Ye Yu didn't hold back anymore. He opened the envelope, took out the letter paper inside and began to read. After reading for a while, he frowned slightly. In fact, the first half was a clichéd greeting, and the focus was on the second half. General Chu said he The descendants of the royal family of the Jokhang Kingdom have been found, and they have been taken to Jingbian City.

In the letter, General Chu’s tone was quite excited, as if he had won a big prize. Ye Yu folded the letter after reading it in two lines, and thought to himself, probably for General Chu, who has deep-rooted loyalty to the emperor, this incident brought surprises. Nothing less than winning the lottery.

Chu Xufeng said in a heavy tone: "I received this letter two months ago. Generally speaking, my father would bring a letter every other month with a flying pigeon, but it has been two months now, and I But no more letters."

After hearing what he said, Ye Yu immediately understood, "Do you suspect that something happened to your father?"

Chu Xufeng frowned and replied: "There should be no fear of his life. After all, his prestige in Jingbian City is extremely high. If the so-called descendant of the royal family has any brains, he would not choose to kill the donkey at this time."

Ye Yu pondered for a while, then asked him, "Then what are you thinking now?"

Chu Xufeng didn't hide it from him, and said truthfully: "I'm going to take Jia Yi and the others back to Jingbian City. If everything is all right, I'll go visit him. If something really happened to my father, I'll find a way to bring him out. .”

After hearing what he said, Ye Yu frowned tightly, "This is extremely dangerous." If the descendant of the royal family really wants to kill the donkey, they may have a tough battle to fight.

Chu Xufeng nodded when he heard the words, "Even so, I have to go back. I have already mentioned this matter to Uncle Ye. We are going to leave tomorrow. It happens that the weather is good during this time. Although it is cold, there is no snow."

"As for the work in my hands, I will temporarily hand it over to Ye He. He is the best learned of all, and it doesn't hurt to replace us for a while."

Ye Yu hesitated to speak, but in the end he couldn't say anything. Even if it was dangerous, he couldn't stop Chu Xufeng. Like Chu Xufeng, no matter how dangerous it is, he will be desperate.

Chu Xufeng didn't wait for him to speak, but just rubbed his head with his hands, and said gently, "Wait for me to come back."

"Okay." Ye Yu replied, "You must be careful on the road."

He didn't propose to go with him. After all, he knows himself best, and he just dragged his feet. In this serious situation, it is more appropriate for Chu Xufeng, who has been trained for many years, to go with his guards, at least if something happens. In the worst case, they still have the power to fight.

From Jia Yi to Jia Shi are all experienced guards of the Chu family. They grew up with Chu Xufeng since they were young. They even trained together, not to mention their strength, but their tacit understanding.

Before Chu Xufeng left, Mother Ye specially made a lot of dry food for them. All kinds of dry and hard wheat cakes and steamed buns are indispensable. In addition to these, there are four cans of meat sauce and egg sauce, not to mention pork jerky and the like up.

The only regret is that although there are seven horses in their city after breeding, there is still no way for each of them to have one horse. When Chu Xufeng left, he could only get five horses, but one horse is enough for two people to ride together. Yes, after all they don't need to bring anything, the horse is only used for transportation.

After Chu Xufeng left, Ye Yu was often worried, extremely worried about their safety, but something happened soon, which temporarily diluted his worries.

To talk about this matter, we must first talk about the school system of Jiwang City.

Now there are two different school systems in Jiwang City, one is an enlightenment class for children, with five days off and two days off, and they have to study in the school all day for five days, and the other is a literacy class for adults, but They only need to go to the school for an hour every night.

The textbooks used by the two are basically the same, and the initial learning process is also similar. They both learn basic textbooks such as the Three Character Classic and Hundred Family Names. After about one or two years, everyone can read and write. There is a big difference. Adults are basically graduated after completing literacy and do not need to go to school anymore, while children need to continue to study in depth. First of all, various hunting knowledge and farming are taught by veteran hunters and veterans for many years. Knowledge, such as how to lay traps, how to deal with fur, how to fertilize the food planted in the ground, how to deal with vegetation when pests appear, and so on.

In addition, there are basic herbal medicine courses and basic wound healing courses jointly organized by Dr. Chen, which include poison identification and medicinal material identification, and at the same time ensure that if patients only suffer minor injuries, they have the ability to find symptomatic medicinal materials for healing by themselves. Bandaging treatment, this course is public, no matter what age or gender you can follow.

The second is about the teaching of mathematics. Ye Yu started to replace the Chinese version of 1234 with the simplified [-] from Ye Tongsheng's help, and marked it with the corresponding Arabic numeral [-]. The latter has gained a lot of People's favor, especially those who are in charge of points registration, especially like this change, because all points are recorded on the household registration of urban residents, and it will inevitably be cumbersome when the number increases and decreases, but it is better now, At least it doesn't take too long to record.

After all the above teaching is over, the students are basically 14 years old, which means they are adults, and then they will make a choice, whether to continue their studies or graduate directly, most people choose after graduation Only a small number of talented people will continue to study under the teaching of Ye Tongsheng, including the Four Books and Five Classics, and various elementary sciences taught by Ye Yu.

The thing that surprised Ye Yu was that among these people, there was a 14-year-old boy who had a fantastic idea. Ye Yu just described the structure of the three things about the water wheel, and he improved the current situation with the Qin brothers. Their plain water mill.

That young man is Ye Rong.

When Ye Yu was called over by Ye Rong, she still couldn't believe it. She didn't really believe it until she saw the wooden invention with her own eyes.

This thing is like a complex version of an irrigation water wheel, but it is true that the water wheel mounted on its vertical wheel is also used for irrigation.

Ye Rong introduced: "As you said, this is mainly composed of a large water wheel driven by water power. A row of levers and a vertical wheel are installed on the extended water wheel shaft. The main purpose of the lever is to move the wheel. The end of the rod makes the pestle reciprocate up and down, so that the rice can be pounded or the grain is hulled. The vertical wheel drives the flat wheel and the vertical wheel at the same time. The shaft where the flat wheel is located is equipped with a mill for grinding. Waterwheel, used to fetch water for irrigation.”①

After listening to him, Ye Yu said in amazement: "You guys really made it."

Ye Rong waved his hand and said, "It still depends on the structure you said, we just follow the steps, mainly thanks to you, Brother Yu."

Qin Muwen also echoed: "If it weren't for you, we really wouldn't be able to do it. Ah Rong originally just wanted to improve the water wheel for irrigation. I really didn't expect to be able to make this kind of agricultural tool that integrates three purposes."

Ye Yu smiled when he heard this. It's really not just his credit. If it was someone else, even if he chewed up the principle and structure and fed them to their mouths, they probably wouldn't eat it, which made him most gratified. The most important thing is that Ye Rong has the most basic challenge spirit to be a scientist, and he is not afraid of difficulties, and his two cousins ​​are even more hands-on. It took only one month to make the water wheel and three things according to Ye Rong's drawings. come out.

Ye Rong looked at the rather tall water wheel Sanshi and said with emotion: "I don't know if it can be used, and if it can be used, what effect will it have."

It's actually quite simple to try it out, but now it's icy and snowy outside, and the rivers are frozen solid. It is estimated that the effect of the hydraulic drive will be verified after the snow melts.

Although it is not possible to try it out, Ye Yu has already asked Father Ye to allocate a large amount of points to the three of them as a reward. What he wants is the incentive effect of the reward. It would be even better if it can arouse more people's interest in science It is said that science and technology are primary productive forces, and they cannot develop without convenient technology, especially technology that can liberate productivity.

Ye Yu watched Ye Rong and the three of them happily leave with their household registrations, and secretly said in his heart, I hope you can have more wonderful ideas in the future.

But this also brings about a problem. The knowledge he brought from the space alone may not be enough. After all, those are too advanced, and the books in his space are only after the founding of the People’s Republic of China. What they need now is knowledge that meets current productivity .

Thinking of this, Ye Yu went to Ye Tongsheng and asked, "Do you have agricultural books?"

Ye Tongsheng shook his head, "No, books like "Qi Min Yao Shu" and "Meng Xi Bi Tan" are not included in the imperial examination."

He immediately said with emotion: "If I knew that there would be no imperial examinations in the future, I would not spend a lot of money to buy the Four Books and Five Classics."

"Who would have expected that." Wang Shu sighed and said, "I was still thinking about being a scholar, but in the end I didn't even catch up with the Tongsheng exam."

After listening to what they said, Ye Yu thought to himself, in this case, he can only go to other places to search, and the Chenhui caravan where Deputy Han is located is a good choice.

The author says:

Note [-]: From Baidu Encyclopedia.

The three things of the water wheel are recorded in the "Book of Agriculture" "The three things of the water wheel, that is, the water wheel shaft, can be combined with three things, grinding, hulling, and grinding. At the beginning, a water mill was set up, and wheat was turned into noodles. A round milling groove is built around the mill. If you want to mill rice, you only need to use the water wheel shaft head to grind and place a husker. Once you have milled rice, go to the husker and put it in a mill, and then grind it along the trough to get mature rice. One machine and three things, It is always ready, it is possible to change, it is not lacking, it is necessary to save, it is sincere and convenient for the people, and it is the potential of creation.”
