When a smile becomes an invitation to death and neatness becomes a strange last word, Detective Zhou Zheng is forced to face the dark side of the world. Three years ago, my sister disappeared mysteriously, leaving only an inhuman symbol; now a series of murders have reappeared with the same mark, and the deceased all died with a smile on their face. Transferred to the newly established "Crime Team", Zhou Zheng discovered that conceptual bodies that feed on obsession and aberrations distorted by pollution are wandering in the shadows of the city. Side by side with a hacker genius, a psychic forensic doctor, and an alcoholic veteran, he is not only pursuing the truth, but also the traces of his sister who disappeared into the "abnormality". All clues point to a mysterious organization that believes in "purification" and the whisper behind the symbol: disciples are coming and rebirth in the pure land.
