Lin Huaigu was laid off and returned to his hometown. He strayed into the mountain fog and woke up in the year of drought. Continuous rains have destroyed the fields and the rice roots have rotted. Qingxi Village will be running out of autumn crops. The government is about to demand food. If you can't pay it, you'll be fined with silver, arrested, or have your land sold. Li Zheng, Qian Youtian, had been waiting for the villagers to bow their heads, especially the two acres of land owned by the widow Liu Qinghe's family near the mouth of the river. Everyone said it was a natural disaster and burned incense to pray for rain and waited for their fate. Lin Huaigu was carrying an agricultural bag with only half a pack of pesticides left. He squatted on the edge of the field and looked at it for a long time. He only said: "This field was not harvested by God, but soaked to death by you." Drainage, fertilizer control, disease treatment, pest control, seed saving, composting, soil improvement, and canal construction. From two acres of rotten root fields to a village full of granaries; from Qingxi Valley to the world's famine relief road. He originally wanted to find Guiwu and return to modern times, but later he found that in this disaster year, he was waiting for him to find a way to survive.
