Corpse Language Code: the Seventh Truth on the Autopsy Table

On a rainy night, a female body was found abandoned in an abandoned factory. The skin from her body was peeled off, and her death was tragic. Forensic doctor Lin Shen discovered a strange symbol during the autopsy, which was exactly the same as the mark at the scene of a cold case three years ago. Criminal police captain Chen Mo received an anonymous letter warning that "the seventh sacrifice is about to appear." As the investigation deepens, the connections between the victims gradually emerge, and all clues point to a long-dead serial killer. When Lin Shen and Chen Mo thought they were close to the truth, they found themselves falling into a well-designed trap, and the real murderer might be beside them.
