Blood Alliance Star Map

On a rainy night, elite forensic doctor Chen Wen was urgently summoned to the scene of the murder of tycoon Zhou Yongchang. On the surface, it looks like robbery, but the metal piece held tightly in the deceased's hand is engraved with a symbol that freezes Chen Wen's blood - this is actually the exclusive symbol of the "Red Rope Serial Murder Case" that led his father to commit suicide twenty years ago! What is even more shocking is that the autopsy revealed that the deceased contained the same rare anesthetic as the victim in the old case, and there was a mysterious scar on the back that was exactly the same as the fifth female victim. The bloody unsolved case that had been sealed for twenty years suddenly restarted, and the cold symbols returned like ghosts. Chen Wen conducted an in-depth investigation and discovered that his father and the deceased had participated in a mysterious activity called "Qingsong Summer Camp" together. However, the road to pursuing the truth is full of thorns and death: the home was broken into by a mysterious person, his father's photos were desecrated and threatening symbols were left behind; key witnesses were brutally murdered one after another; and an anonymous warning was received: "Stop the investigation! Your father's choice is wise." When a dusty list of participants was exposed, the dazzling mark of "Chen Zhiming's son" on the list, and the existence of twin brothers that Chen Wen had never known, pushed everything into a darker abyss. A blood feud spanning two generations, a twisted experiment on human nature, and suspicions within the police station... Chen Wen must uncover the ultimate secret behind the cold symbol amidst heavy fog and deadly threats, face the sinful curse connected by blood, and complete a redemption that is twenty years late. The price of the truth may be life or soul.
