Chu Xuan, a powerful Nascent Soul cultivator from the cultivation world, fails his tribulation and falls into the mortal realm, where he lives in seclusion on an antique street. He relies on absorbing the residual spiritual energy in antiques to repair his damaged Dao Heart. Lin Qingxue, a fallen heiress of a wealthy family, arrives at his rundown shop seeking refuge, carrying a blood jade pendant containing fragments of Chu Xuan's Dao Heart. Because his Dao Heart is closely connected to the heroine's fortune, Chu Xuan becomes her protector. Facing fierce resistance from within the Lin family, Chu Xuan effortlessly resolves one crisis after another with his extraordinary abilities, helping Lin Qingxue restore her family's business and embarking on an extraordinary urban adventure.
