Liang Yibao, a private detective who is heavily in debt, received a mysterious commission on a rainy night to investigate the mysterious disappearance of the daughter of a wealthy businessman. The strange silver powder at the scene caused her to activate the "paranormal detective system". Under the guidance of the system, she was forced to be involved in a series of supernatural incidents, and met Sheng Xin, a mysterious man who had lost his memory but had powerful soul power. The two team up to follow the parallel clues of "system tasks" and "kidnapper tips" to investigate step by step. They discovered that all the cases pointed to a "Blood Wedding" tragedy that was covered up ten years ago, and that the silver powder was the residue of a supernatural substance called "soul dust." It seems that the "Collector" behind the scenes is not simply seeking revenge, but is collecting "strong emotions" and "special souls" related to the tragedy in order to complete a terrible ritual. In the process of solving supernatural mysteries and fighting against other soul master forces to compete for "soul dust", Liang Yibao and Sheng Xin's strength continued to increase, and their relationship changed from mutual use to life and death. In the end, they must face the "Collector" and the real mastermind behind it. While revealing all the bloody truth, they must decide whether to seal the disaster or somehow "end" this ten-year painful reincarnation.
