Codename: Red Silk

Three years ago, a secret operation resulted in the annihilation of the twelve-member special operations team. Gu Lin, the only surviving captain, was nicknamed the "lone wolf destroyed" and spent three years under suspension review. At the same time, Song Ling, the youngest criminal psychology profiling expert in the provincial department, accidentally killed his partner Lin Kai during an arrest. From then on, he was dismissed and lived in self-blame and nightmares. Three years later, an unknown female corpse was found in the moat, with a series of mysterious numbers engraved on her palm. This string of numbers turned out to be Song Ling's original "criminal genetic marking method" - a coding system that only she and her deceased partner knew. The tactical hand signals on the dead man's arm pointed to Gu Lin's lone wolf commando team. Two people who shouldn't have crossed paths were tied together because of this corpse. They suspected each other and were forced to cooperate, but found that all the clues pointed to the same place - the border town where twelve warriors were buried, Blackwater Town. And deeper mysteries are emerging: the late partner Lin Kai seems to have left traces after his death; the drug lord "King of Hell" who was supposed to be in prison had a secret relationship with Gu Lin; a top-secret file with key pages torn out, the last person who reviewed it was actually Lin Kai himself...
