Shen Ni transmigrates to a farming family in the Great Mo Dynasty, reborn as the youngest daughter of Shen Ding and Fang. Drawing on her modern knowledge, she persuades her family to cultivate sweet potatoes and render oil from pig offal. She sets up a market stall selling mountain potatoes and spicy pig lungs. Seizing an opportunity, she sells her braised meat recipe to earn her first fortune and buys a house. Her family then establishes a sweet potato vermicelli workshop, secures a major order from a restaurant, purchases servants to expand their workforce, and opens a food shop in the county town, selling delicacies such as hot and sour noodles.
