Shen Qilin was forced to be involved in an urban supernatural case due to a bizarre suicide case. As team members gradually gather together, story lines intertwined with weirdness and reality unfold. The six major volumes focus on different cases, which are both independent and implicated in each other, ranging from urban legends to ghosts in ancient houses, from Internet mysteries to folk taboos. In the confrontation between reasoning and the supernatural, the boundaries between humans and ghosts become increasingly blurred, and the protagonist gradually approaches a "hell labyrinth" that involves the secrets of his own life and the entire city. In the end, the truth was revealed, all story lines returned to one, and the dust settled under the night of the city.
