Modern woman Nangong Qianqian is unexpectedly reborn, her soul entering the body of Lin, a poor farmer’s wife in Qingxi County of the fictional Great Jing Dynasty. Her in-laws’ home is bare, and a young daughter is still crying to be fed. Drawing on her modern agricultural knowledge and business sense, she starts by improving farm tools and planting high-yield crops, then makes and sells specialty foods and organizes a farmers’ cooperative. Step by step, she leads the Lin family out of poverty and turns them into one of Qingxi County’s best-known merchant families. By chance, she encounters Regent Ye Sheng, who is traveling incognito to inspect disaster relief. He is impressed by her clever relief plan of exchanging work for food. Later, hoping to secure her trade routes and find a powerful patron, Nangong Qianqian goes to the capital, where she and Ye Sheng’s paths truly begin to cross.
