In the gray city of parallel time and space, reality and weirdness merge, and the dark layer opens and is full of dangers. College student Jiang Yan complained about the supernatural live broadcast and was involved in the supernatural cold case investigation team. He accidentally got a golden finger and has the ability to "complain and predict". This ability can rewrite the rules and make it a special existence. Teammates each have their own special abilities, and Jiang Yan stands out in the investigation because of this. Later, he will face the evil god as a "lucid ironist", break the seal of the law of cause and effect, and end the reincarnation of Gray City.
