At the end of April, the cuckoo called one after another, "Grandpa and Grandma, cut wheat and plant crops", which is the busiest time of the year when it comes to the solar term of mango seeds, harvesting wheat and planting crops.

Lan Yi didn't have to go to the ground, so she took the child over to help the second aunt cook and watch the child.

The second uncle's family planted a total of seven acres of wheat, and the family was busy pulling out the wheat in the field, transporting it to the drying field, and then dropping the lower half with a guillotine, and the upper half of the wheat ears were dried on the field, and then threshing several times with a stone mill. These are all hard work, people with livestock are more relaxed, and those who rely purely on manpower like the second uncle's family are basically women for men and men for livestock, and they are tired every day and can't straighten their waists. Even Liu, who likes to talk a few words on weekdays, is so tired that he doesn't even have the strength to speak.

After the wheat is pulled out, water is put in the field and the rice is planted, and it will be busy for more than ten days. When the water is released, the people in the field also hold a simple ritual to worship the heavens to thank God for their protection and make the fields abundant.

Lan Yi was helping to watch the wheat in the wheat field at the edge of the village, and when the time came, she also prayed to God with her hands together. Since the time travel, she has changed from a staunch atheist to a skeptic, believing that there must be some kind of force in the underworld that will allow her to appear in this strange time and space. She hopes that God can bless her, so that she and her children can continue to live a stable life, so that the enemy family cannot find here.

The weather is beautiful, the wheat is down, dried on the field, and the seedlings are planted in the ground, and the new green should be shining, which is very gratifying.

After the wheat is harvested, Lan Yi no longer has to go to her second aunt's house to help, she takes her children to tidy up the yard or go to the slope to weed the soybeans and mung beans. The bean seedlings on the slope are very neat, but the exposure to the sun in the past few days has dried the soil in the field, and the seedlings are naturally not spiritual, Lan Yi is also looking forward to the rain as soon as possible, she is also strange in her heart, Huangxian should not be far from the sea, it is said that the rain should be abundant, but she has only had two rains in the days she came, and there was no violent storm, she has not studied the weather much, I don't know if this is a normal phenomenon. But according to the villagers, in June and July, there is still a lot of rain here, and this rain also makes some harvest on the slopes of the mountains that are difficult to irrigate.

But relying on the sky to eat is risky after all, and Lan Yi has been wondering if there is any way to divert stream water to irrigate the slopes and increase the yield.

She thought about it carefully, and remembered the old overturned car she saw when she went to the countryside of Jiangsu, Zhejiang and Yunnan to play, relying on the power of the water itself to make the overturned car work, and transported the water to a high place to irrigate the land. She read in the "Geography of the Great Zhou Dynasty" that the previous dynasty, that is, the Tang Dynasty, had let wheel craftsmen make a large number of overturned carts and distribute them to the people on both sides of the Zhengbai Canal for irrigation of paddy fields, and many areas of the Great Zhou Dynasty have begun to use overturned carts or cylinder carts for irrigation, "which is a hundred times more clever than usual."

Lan Yi thought about it, and took advantage of the fact that everyone was resting at home after the busy farming in the past few days, and took the children to visit Zhao Lizheng's house with tea, Zhao Lizheng can be said to be the most well-informed person in the village, and he should know about the overturn.

Zhao Lizheng happened to be at home, Lan Yi entered the house, put down the gift she brought, and politely thanked Zhao Lizheng for her help, Zhao Lizheng helped her handle the household registration a few days ago, and their mother and son are now legitimate Beigou Village people.

Zhao Lizheng's wife, Hua, is in the same village as Wang Linshan's mother, Qian Nai, and she is also very cordial when she sees Lan Yi. Lan Yi chatted with Hua Shi for a few words, and then mentioned today's topic with Zhao Lizheng.

"Uncle Yang, I see that our village released water to water the fields and plant seedlings a few days ago, but there is no water in this slightly higher place, and rice cannot be planted, so the harvest must be a lot less, right?"

Zhao Lizheng didn't know why Lan Yi wanted to bring up this topic, but he also nodded: "Yes." After all, it is not a matter of relying on people to carry water little by little to water the fields, and it will take several days to water it once, and it is natural that rice cannot be planted. ”

"Then why doesn't the village have to roll over?" Lan Yi asked curiously.

"Overturned?" Zhao Lizheng was a little confused, and Hua was also at a loss.

"Yes, I read in the book that our Da Zhou overturned car can transport water from a low place to water the farmland."

Zhao Lizheng was very interested when he heard it: "We still have such good things in Da Zhou?" Lin Shan's family, have you seen it? ”

Lan Yi shook her head embarrassedly: "I've only seen it in books, and the descriptions in the books are very clear, so I have some impressions, I'll draw it for Uncle Weiyang another day." She didn't expect that Zhao Lizheng had never seen a rollover car at all, but she could understand it when she thought about it, after all, transportation and communication were not developed in this era, and message transmission was very slow. Huangxian is not a rich rice and grain town, and the imperial court did not pay attention to agricultural cultivation here, so it is inevitable to ignore it.

"Okay, if we really have this thing, we can grow a lot of food in this field." Zhao Lizheng said with great interest.

Subsequently, Zhao Lizheng asked Lan Yi about the relationship between Lan Yi and Mrs. Mi in Meixian County, and Lan Yi simply said that she and Mrs. Mi hit it off at first sight and recognized the sisters.

Zhao Lizheng was relieved that the wife of Lord Mi of Meixian County was the eldest lady of the Xia Mansion in Huang County, and Lan Yi had a different surname from her, not from the Xia family. If it is said that it is a cousin, Lan Yi should not be alone with the child here, and should go to the Xia family.

"Yu'er's pension silver is only 100 yuan a year. Yamen En rewarded you for your kindness and granted you the right to buy more land and exempt you from the rent for ten years for less than 10 acres. ”

Zhao Lizheng only told the official who handled household registration and other matters that Lan Yi was the wife and sister of Lord Mi in Meixian County, and stuffed some copper coins into the past. And things went smoothly.

"Excuse me."

Hua Shi took over at this time: "Lin Shan's family, the rent of these ten acres of land is a lot, you carefully sum it up." Raising two children is a lot of food and drink. ”

Lan Yi nodded: "Uncle, I will." If you have money in your hand, you will come to Uncle Wei Yang immediately, please help me keep an eye on which family wants to sell the middle and high-quality fields. In other words, my sister also wants to enjoy good policies, but she doesn't have any money in her hand! Let's wait until we have the money. Lan Yi's family can't be moved, she has to keep it just in case, the cost of buying the land is too big, or wait until it settles down.

Coaxed the two children to sleep, moved the small table in the kitchen to the locust tree in the courtyard, Lan Yi lit the dried wormwood to drive away mosquitoes, and Lan Yi carefully recalled the structure of the overturned car.

The newly planted grapevines in the courtyard, the chirping chickens looking for food, the neat vegetable garden, the goats sleeping peacefully with their eyes closed, the dense locust trees, and the distant cicadas singing, if you ignore the carbon bar she is holding in her hand, it should be harmonious and natural.

"The water flow speed of Huaxi is slow, the drop is small, and the overturning car cannot rely on water conservancy, but has to rely on manpower and animal power to promote." Lan Yi turned the charcoal pen in her hand and habitually touched her forehead with the pen. The charcoal pen is made of a cloth wrapped in a carbon strip, which is specially fired when she cooks on the fire, which is more convenient for her to write and draw than a brush.

Overturning is also called treadmill and water wheel. With a plank as a groove and a tail immersed in the current, there is a small axle and a large axle at the other end, which is fixed to the wooden frame of the embankment. When stepping on the crutch, the large wheel axle rotates, driving the continuous ribbon plate leaf in the groove to scrape the water up, using the principle of sprocket transmission, with manpower (or animal power) as the driving force, driving the wooden chain to turn over and over again, and the scraper or bamboo tube installed on the wooden chain can lift the river water to the shore along the trough, and continuously irrigate to the higher fields. Lan Yi had seen this kind of structural drawing of the overturned car in a book before, and she had seen the real thing in the countryside, she had some sketching skills, and it was not difficult to draw.

"In terms of manpower, there are two kinds of pedals, foot pedals and hand cranks, and I have only seen foot pedals. Animal power...... Cattle turn over? Lan Yi supported his forehead with his left hand, his long eyebrows knotted lightly, and his right index finger tapped lightly on the table, "There are two kinds of pedals and ox turnovers, it is estimated that it is more likely to choose pedal rollovers in the end." ”

After the painting was finished, Lan Yi washed off the black carbon marks on her hands and forehead, and after the two children woke up, she took the children to the wheat field to find Uncle Wang, who had been taking care of the dehydrated wheat in the wheat field for the past two days. She didn't plan to go directly to Zhao Lizheng for this overturn, and it was more appropriate for the second uncle to do it.

Lan Yi explained the intention and showed the drawings to the second uncle, explaining the benefits and usage of the rollover. The second uncle's family has ten acres of mountainous land, and if this overturned car can be used, it will naturally increase a lot of production.

"Second uncle, look, we have a canal for releasing water, and if you want to irrigate the sloping land when the time comes, you can open the canal and turn it over, and you can get the water when you step on it or pull it by a cow, and the water will flow to the ground with a trough, and it will save a lot of effort to water the ground."

"Everyone, what is this, if you can get this 'rollover' out, it's a good thing. Not only is it used to divert water to irrigate the high slopes, but when the rain is heavy, the water in our paddy fields can also be discharged with a dump. Second Uncle Wang's eyes lit up, as an old cropper, he knew the benefits of overturning. If this overturned car can be used, not only can the sloping land and paddy fields be harvested in drought and flood, but even a few more pieces of wasteland can be opened, and there is no need to pay rent for the first five years of wasteland, as long as it is harder, there will still be a harvest.

"Old man, do you remember this overturn?" Lan Yi lost her brain memory, and now she can draw such a thing, does she remember?

Lan Yi shook her head and said, "Second uncle, this overturned car was seen in a book on the way back." I still can't remember vaguely what happened before. ”

"No defense, no defense. There are really a lot of good things in the book, using leaves to fertilize the ground, overturning the car to water, and so on, all these things are remembered, this is a good book. Some time ago, she sprinkled fertile soil in the mountains, and Second Uncle Wang naturally saw the wonders, and also let the two sons bear a lot of sprinkles in their own fields.

"Yes. Second uncle, I'm looking at wheat here, you take the drawings and go to Uncle Weiyang to discuss whether it can be used? Lan Yi brought the topic back, if Second Uncle Wang asked if she read it in a book, she would really not be able to answer, she had only heard of the book "Qi Min Yaoshu" but had not read it, where did she know what it recorded.

"Done. This slope is about to be watered, so it can be quickly brought out and save a lot of trouble. Second Uncle Wang nodded.

"Second uncle, if this drawing can be used. Please also tell Uncle Weiyang not to say that I painted it. Lan Yi told her that she had good intentions when she drew the overturned car, and she didn't want to cause trouble because of it.

"Everyone, this is a good thing to accumulate blessings, even if you painted it, it's nothing." Second Uncle Wang thinks this is a good thing, and saying it can also make people look up to Lan Yi a little bit.

"Second uncle, this overturned car is already there, I just drew it in the book, and I didn't have any credit, so I still don't say it well." Lan Yi insisted.

"Okay, I'll mention it to Uncle Yang with you."
