A modern soul is reborn in the cultivation world as a palm-sized plaster monkey. Fortunately, it comes with a special innate talent: as long as it clings to a target, it can continuously devour their spiritual power. After accidentally swallowing the most powerful sacred beast, the Primordial Night Dragon, it clings to Su Qinghan, the seriously wounded and dying saintess of the Beast Taming Sect, and forms a life-sharing contract with her. A dignified saintess paired with a despised plaster monkey—overnight, Su Qinghan is demoted to an outer sect disciple, schemed against by her own family, and dumped by her fiancé, becoming a laughingstock throughout the sect. But nobody knows that the monkey trampled into the mud is evolving step by step as it devours more power.
