Wu He, an intern at the Modern Academy of Agricultural Sciences, accidentally traveled through Qingmao Village and became a peasant girl who fainted from hunger. When she woke up, her parents were dead and she was left with only two younger siblings (A Zhi, seven years old, and A Yan, five years old). The rice tank at home was at the bottom, and the landlord was demanding rent. In times of desperation, he activated the "Bad Years Fullness System" and received ten kilograms of brown rice on the first mission, so that his younger siblings could have enough to eat. She used system rewards to grow fast-growing potatoes and drought-resistant wheat seeds, secretly dug cellars to store grain, and exchanged secret pickles for money to buy farm tools. In the process, he outsmarted the evil neighbors who stole food, exposed the landlord's food scam, and gradually inspired the villagers to open up wasteland and grow food. From filling the family's stomach to leading the whole village in fighting disasters, Wuhe not only protects his family, but also becomes a "coordinate of hope" in troubled times.
