In the darkness of modern cities, people with special abilities use "rules" to divide their territories and check and balance each other. Chen Bo appears to be an ordinary fresh graduate, but in fact he is an alien who has awakened the power of "Devil Logic" - he can transform all actions into a contract game and strengthen himself by taking away other people's rationality and emotions. In order to hide his identity, he joined the "Tian Ping", a superpower supervision organization, and was forced to deal with various superpower crimes. At this time, "perfect disappearance cases" appeared one after another in the city: the victims were all high-level supernatural beings, and there were no traces at the scene. Chen Bo traced and discovered that the man behind the scenes was actually Lin Yuan, a genius who had been abandoned by "Tian Ping". Lin Yuan took advantage of loopholes in the rules to build an unsolvable criminal chain, and gradually turned into a revengeful demon. What's even more deadly is that Lin Yuan's every step is forcing Chen Bo to reveal his true abilities, and even tempting him to voluntarily abandon his humanity. The two engage in a brain-burning duel around logic, evidence and superpower rules, and Chen Bo must unravel Lin Yuan's "judgment chess game" without being hunted by the organization, otherwise the entire city will become a purgatory battlefield for superpowers.
