Li Sui'er, a PhD in agricultural science, transmigrates to the famine-stricken years of the late Ming Dynasty. The moment she opens her eyes, she finds herself marked with a straw tag for sale. She carries a mu of experimental farmland with her, stocked with all kinds of high-yield crop seeds. To survive, she uses a cassava detoxification method to save her entire village and exposes a trap involving inferior grain. As displaced refugees turn to looting and troublesome relatives make things difficult, she persuades her fellow villagers to migrate a thousand miles to Chuzhou and reclaim wasteland for farming.
