Xu Qingzhou, the leader of the agricultural science and technology project, was transformed into the thirteen-year-old second son of a tenant farmer in the Northern Song Dynasty after an accident on a rainy night. My parents are honest, my elder brother is tough-talking, and my two younger sisters are so thin that it makes people feel distressed. The family does not have an acre of their own land, they owe rent, they borrow grain, their pots are on the bottom, and there are debt collectors outside the door. He only has a remnant of ancestral jade in his hand. There is a small field in the residual jade, and there is also a little jade spirit he calls "Wen Ce". The Questioning Council will directly tell him the basic usage and restrictions of Canyu and Cuntian, but it will not send out tasks or give rewards, nor can it conjure food and money out of thin air; it can check for him the common sense of farming, warehousing, diet, and life that he has seen, learned, and used, and it can also remind him not to bring things in front of others whose origins are unclear. So Xu Qingzhou started from a pot of bean sprouts, raised vegetable seedlings, raised sick chickens, dug shallow trenches, established rules, sold fresh vegetables, paid off old debts, went to the Shen family courtyard to read old books, and also picked up the road to study that was interrupted by poverty. He wanted to feed the family first, then let the tenants have land, the poor families have a way, and the world has countless warehouses. Many years later, the Jin people went south and the mountains and rivers were broken. The young man who once counted beans and firewood in the mud house and protected his sister's page will finally get up from under the hay, regain the lost ground, and rebuild the country.
