Jiang Yu is a lively, mischievous young woman from the modern world. While out shopping, she accidentally falls into a sewer. When she opens her eyes again, she has transmigrated to a remote, barren mountain village and become an orphan with the same name, only fifteen years old, timid and insecure, and neglected by her family. As the original owner's memories flood her mind, Jiang Yu takes in the mud-brick house with its bare walls, her cold and spiteful relatives, and days spent going hungry. She resolves to shed the original owner's cowardly nature and use her modern perspective and quick wits to reclaim the wilderness, build wealth, put the worst people in their place, and turn her life around. From a pitiful girl everyone can bully, she becomes a respected leader in prosperity throughout the village and even the whole town. In the end, she leaves the mountains and makes a dazzling life of her own.
