A female technician from an agricultural sciences institute transmigrates into the body of an unwanted, malnourished girl living during a famine, who is about to be sold by her own family for fifteen jin of coarse rice. Relying on her expertise in identifying medicinal herbs and cultivating crops, she climbs the mountains to gather herbs and makes a wager to save herself. Starting from the brink of being sold off, she turns her fate around through farming and the development of modern agricultural techniques, transforming twenty mu of barren hillsides that nobody wanted into fertile farmland yielding 2,000 jin per mu. Come and see how this famine-era farm girl turns her fortunes around, starting with being sold off and making her way through farming!
