The protagonist Lin Sui is a graduate student majoring in rural farming at China Agricultural University. He is deeply involved in traditional farming techniques and firmly believes that the farming wisdom passed down by his ancestors for thousands of years will never become outdated. During a field trip in a rural area, in order to protect an ancient copy of "Essentials for Elevating the People" passed down from her ancestors, she accidentally encountered a landslide. She opened her eyes again and traveled to the interstellar era 10,000 years later. Lin Sui looked at the polluted interstellar land and the "Essential Art of Elevating the People" passed down from her ancestors in her hand, and made a decision: she would re-cultivate the farming civilization of her ancestors in the interstellar era.
