For several days, Cheng Wanwan stayed in her room reading.
The most common items in her mall storage room are books. The large bookshelves on all sides are filled with various agricultural classics. She reads them basically every day, and only reads less than one tenth of them. The books on this bookshelf are only one ten millionth of those in the mall.
It would be impossible for her to finish it all on her own.
Perhaps, a library can be built...
We can indeed discuss this matter with Master Yu, but there are other more important things now.
After reading the book for a few days, Cheng Wanwan had a clue in his mind, so he called Mr. Zou and others over for tea and discussion.
"This is the floor plan of a human-powered rollover." Cheng Wanwan put a clear drawing on the table, "Do you guys have any ideas?"
Several adults looked carefully. In fact, the human-powered rolling cart was first invented by the palace. It was used by the emperor to sprinkle water when traveling to ensure that there was no dust. Later, after many years of development, it was gradually used in agriculture, but the workmanship was complicated and the cost was high. It is relatively expensive, and only wealthy people can afford it.
Lord Zou looked at it for a long time but didn't see anything fishy. He turned to look at Lord Li. After all, Lord Li was in charge of things like canal irrigation.
Mr. Li was stared at by several pairs of eyes, and he considered and said: "The rollover uses human power to drive the sprocket to rotate, bringing water from low places up to solve the problem of dry land irrigation. The conventional rollover is about one foot and two feet long. If you want to irrigate more, The ground can be made longer..."
Cheng Wanwan listened patiently to what he said, and then said: "Making it longer means that more manpower is needed. Moreover, after the car is rolled over for too long, it will be difficult to extend the leg strength, and the water below may not be successfully lifted up. This is not the point. The point is that the longer it takes, the higher the cost will be, and the people at the bottom cannot afford it."
Mr. Zou heard something: "Do the Sui'an people have any good ideas?"
"I have an immature idea." Cheng Wanwan said calmly, "You have all seen windmills. When the wind blows, they start to rotate. If the wind doesn't stop, the windmill will not stop either. It requires any manpower. If the overturning car is made into the shape of a windmill, well, the wind force may not be able to blow it. However, the wind force can be replaced by something else, such as... Hey, I can't think of it at the moment. My Lords Any good ideas?"
Everyone present was shocked.
They all knew about windmills, but they never thought they could be connected with irrigation tools.
When people from Sui'an mentioned this, it was as if a small hole had been opened in their brains, and some fantastic ideas popped out.
Mr. Zou stood up suddenly: "When I went to Jiangnan, I saw a large water-turned spinning wheel. It uses water to turn the spinning wheel. It does not require manpower or animal power, which saves a lot of costs... Sui'an people, can we also use it?" Where’s the water power?”
Mr. Li's eyes lit up: "I understand, I understand. Listening to someone from Sui'an is worth ten years of reading!"
Mr. Yu said: "But if the straight rollover is made into a windmill shape, the cost will only be higher, and the people at the bottom may not be able to afford it."
"If we can successfully build a hydraulic turntable, we can draw a large amount of water by relying on hydraulic power, which means that more fields can be irrigated, maybe thousands or even thousands of acres. Perhaps, a village can make two or three of them." It's enough. The whole village has to pool the money and distribute it to each household. In fact, it's not much." Cheng Wanwan took a sip of tea and said, "I'm a woman and I don't know exactly how to do it. Whether it can be done or not depends on you adults. .”
Mr. Li's face was full of excitement: "People of Sui'an, don't worry, I will definitely work hard and live up to the hard work of the people of Sui'an these days!"
He went down to prepare in a hurry.
Cheng Wanwan asked Zhao Dashan to ask Old Man Zhao for help. To do this kind of thing, theory and practice must be combined. No matter how perfect the idea is, it is useless if it cannot be done. With Old Man Zhao helping to come up with some ideas, this matter can be done. Land as soon as possible.
For the next period of time, several adults stayed at home and were fascinated by the study.
All Cheng Wanwan can do is go there occasionally. If they encounter a bottleneck, she will "accidentally" give them a few pointers. After they suddenly realize, she will "retire". As long as the farm tools can be made, she will not Don’t care who gets the credit.
In early February, when the winter cold gradually dissipated, news came from Mrs. Lin.
"Sui'an people, I have the honor to come to see you." Mrs. Lin said with a relaxed smile, "After I wrote to the capital at the beginning of the first year, my eldest aunt admired the Sui'an people very much. I heard that Mr. Cheng is the nephew of a native of Sui'an, and he immediately started to organize it. Not long ago, the Lin family held a flower viewing banquet and invited some ladies from the capital to come. The eldest aunt contacted two or three of the elders who were ladies, and the other party also had some After the intention was expressed, a meeting was arranged for the children.”
Cheng Wanwan's heart for gossip was aroused, and she listened with interest.
She knew that this was a blind date between aristocratic families in ancient times. Of course, it was not a private meeting, but the elders were present. Using other excuses to let the two children meet and say a few words, she could usually get a rough idea.
"One is the concubine of a third-rank official. Although she is a concubine, she is recorded in the name of her legitimate mother. She is well-educated and skillful. She is my eldest aunt's favorite candidate. The other is the eldest daughter of a fourth-rank official. She is very tall. That's called a beautiful woman, not to mention her beauty. The main reason is that she has the means. Some of the general affairs in their house are taken care of by this eldest daughter. The last one is the third daughter of a fifth-rank official's family. She is a little older. She is younger, she is only fifteen this year, she has a more lively personality, she always smiles when she meets everyone, she is very lovable."
At this point, Mrs. Lin paused and said, "Sui'an people, guess who you talked about in the end?"
Cheng Wanwan really started to guess.
Although the first one is a concubine, she was born into a third-grade family, which is a bit high for the current Zhao'er.
The second and third eldest daughters are both legitimate daughters. To a certain extent, the second eldest daughter is more in line with the elders’ requirements for a daughter-in-law. However, the eldest daughter means sensible, and Zhaoer is also sensible. Two sensible people Together, this life is a bit too boring.
She said: "For the sake of peace in the future, Zhao'er may be willing to marry the eldest daughter of the Sipin family... Mrs. Lin also knows that Zhao'er was born in a poor family and has many poor relatives. Only a capable daughter-in-law can To calm down those country people who don’t understand the rules of the capital city. But if you ask Zhao’er who will be attracted to her, I think it should be the lively third lady.”
"Sui'an people really know their nephews." Mrs. Lin said with a smile, "After Master Cheng met the three ladies, my eldest aunt knew that he liked Miss Situ San because, Master Cheng is so serious. The person was actually amused... Later, the eldest aunt asked him to chat alone, hinting in her words that he would choose a mistress who would be more beneficial to his future career, but Mr. Cheng refused. He said that the second aunt hoped that he would find someone he liked. Woman, then he hopes that the person standing next to him is his sweetheart, rather than marrying her back for some purpose, which is unfair to the woman."
Cheng Wanwan laughed: "Zhao'er is such a person. What he wants to get, he will use his own ability to get it, rather than relying on the people next to him."
This is the reason why she has always admired Zhao'er. She helps him for free, not to ask for anything in return, but to hope that he will stand on the stage that belongs to him and shine with his own light.
However, a person who leaves the countryside will be burdened with tremendous pressure. The Cheng family will be Zhaoer's lifelong pressure.
I don't know if Miss Situ can resist it.
