Village doctor Lin Yu accidentally activates an ancestral jade pendant and is passed down by a fairy. He has extraordinary medical skills and spiritual power, and protects Taohua Village with his supernatural powers: he rescues the bullied widow Wang Chunhua, cures the villagers' chronic diseases, sees through the scams of profiteers, and leads the villagers to improve peach orchards and sell fruits to escape poverty. He gradually grew up, resolved the crisis, revitalized the village, and became a hero respected by the villagers.
