On a rainy night, Yun Qingyuan, the fake heiress discarded by the Su family like worthless trash, discovers that she is actually the long-lost biological daughter of the Yun family, missing for nineteen years! A phoenix birthmark lies hidden behind her ear, and she possesses a lost art of mystical medicine. Her silver needles can save those on the brink of death, while her talisman papers can suppress evil spirits and sinister forces. The materialistic Su family bitterly regrets their actions and desperately tries to curry favor with her, while the seemingly innocent Su Ruoyao is willing to sacrifice her own fortune and conspire with an evil sorcerer to destroy her. After returning to the Yun family, Qingyuan receives her parents' unconditional affection, gradually wins over her two prejudiced cousins, and encounters the exceptionally fortunate and powerful Li Jinci. The two fall for each other and join forces as equally formidable partners, exposing conspiracies, confronting the mysterious sect's antagonist known as the Profound Master, destroying evil and dispelling dark forces. Together, they remain true to themselves and welcome the light!
