The world is divided into three realms: the human realm, Yuandu, and the Nine Heavens. The gods in the Nine Heavens are hypocritical and greedy, while Yuandu is a gathering place for outlaws who shelter homeless monsters.
Yun Chijin, a half-hearted money-maker, is forced to get involved in a weird "paper man ghost marriage". When the groom pretended to be dead, Long Wuyuan, the mad leader of Yuandu who was frightened by the news, crushed the coffin and snatched the bride from the sky. He not only kept her captive by his side, but also forcibly signed a concentric contract.
In order to survive and repay the contract, Yun Chijin was forced to follow this yandere tyrant without a heartbeat and solve a series of strange folklore unsolved cases (human skin with red makeup, Qishui Village without girls, etc.). During the extreme push and pull of investigating the case during the day and testing at night, Yun Chijin discovered that she was not only the Nine-tailed Fox Queen of Tushan who was exterminated thousands of years ago, but the empty heart in Long Wuyuan's chest was the "Heart-Protective Reverse Scale" that he dug out and stuffed into her body in order to protect her remaining soul.
Faced with the hypocritical Master Bai Yueguang's pressing step by step and the curse of reincarnation, this time, it is the Nine-tailed Fox Queen who kills across the three realms for love: "Those who have no heart, I will be his heart!"
