Shen Qinglin, the master of the Underworld Palace of Rebirth, has been in charge of the trial of sinful souls for five hundred years. Due to the investigation of a major case, he was slandered by twelve sects and sealed under the Yin Mountain.
Five hundred years later, the seal was loosened, and her remaining soul escaped from the trap. By some strange combination of circumstances, she possessed Lin Xinyi, a modern white-collar worker who committed suicide by jumping off a building. The original owner was so resentful that he signed a causal contract with her: in exchange for the right to use his body, she would help him complete three things: revenge on the scumbag, protect his sister, and take care of his mother with dementia.
As a result, before the first thing was completed, she was forced to get married for the second time.
Jiang Zhiyan, the prince of the Jiang family in Haizhou, is the number one dandy who does not have a proper job. He spends his days showing off his car, body, and abdominal muscles. Because of the "conquering the wife's life", no one dares to marry, so she can only find someone to fake marriage to celebrate. He fell in love with Lin Xinyi, who was "not afraid of death", but he didn't know that he was not only marrying his "second wife", but also the deceased master of the palace who frightened the three worlds five hundred years ago.
During the day, she is a white-collar worker who is indifferent to social fears, and at night, she is the master of the underworld who is tracking down her enemies. There is also a complaining orange cat (possessed by the original owner) and a "cheap husband" who is getting more and more weird.
When enemies from five hundred years ago appeared one by one, and the truth that had been slandered gradually emerged, Shen Qinglin discovered that this "fake marriage" seemed not that simple.
