C City is gripped by fear. A series of murders leave behind bodies completely drained of blood. The victims, all young white-collar women, have no apparent connection except for the gruesome way they died. The police find a disturbing detail—traces of milk mixed with human blood left at every crime scene. Rumors spread that the killer is no ordinary human but a vampire, a creature that has lived in the shadows for centuries.
Detective Fang Mu, a quiet but brilliant university student, is unexpectedly pulled into the investigation. The lead detective, Captain Luo Wen, is skeptical of Fang Mu’s abilities but quickly realizes the young man has an uncanny gift—he can see patterns others miss. Fang Mu’s deductions lead the police to a suspect, a man with a strange obsession with blood. But is he truly the monster they seek, or just another pawn in a far more complex game?
Meanwhile, an unrelated yet equally horrifying event unfolds. A promising graduate student suddenly snaps, attacking his closest friend with brutal force. His eyes are empty, as if under a trance. When questioned, he claims he remembers nothing. Hypnosis? Or something far darker? Fang Mu begins to suspect a terrifying link between the cases.
