Blood Symbol

Former forensic doctor Qin Feng was forced to resign due to an "unsolvable and mysterious case" three years ago. He went dormant in the old city and opened a humble private detective agency, working with cold case files all day long. Until one rainy night, female college student Su Yong came to the door with her sister who was mysteriously missing after being "possessed by a ghost". The bloody symbols left at the scene were exactly the same as the unsolved case three years ago. A series of strange murders followed one after another: "Murder in the Mirror" in an office building at midnight, "Screaming Living Corpse" in an abandoned hospital, and "Curse Reincarnation" in a deep house in an ancient town. The deceased had witnessed supernatural phenomena before his death, but no trace of man-made traces could be found at the scene. Qin Feng relied on the keen observation and hard-core reasoning skills of a forensic doctor to peel away the cocoon in the horror fog, only to discover that behind the case not only involved a series of murders spanning twenty years, but also hidden the game between human nature and "alien space".
