After former detective Guan Yu resigned, he made a living by sorting out old unsolved cases. However, in a pile of old case files, he accidentally stumbled across a ten-year-old unsolved case involving his father's "accidental" death - the victim Li Wei, who was marked "suspected to be murdered" in the file, actually appeared in front of him on a rainy night three days ago. Ten years ago, Li Wei disappeared after reporting sewage discharge from a textile factory. His father Guan Ming, the factory director, fell from the top floor of an office building and died soon after. The police closed the case as an accident, but Guan Yu has always been suspicious.
A mysterious text message came suddenly, using "the secret of Li Wei's life" as bait, forcing him to go to the abandoned old textile factory site alone for an appointment. The vague four-character annotation "Zhou, Fu, Liu, Zhang" at the end of the file involves hidden secrets that have not been unearthed in depth at that time, including his father's strange instructions before his death, the shady story of the textile factory's sewage discharge, and the whistleblower who came back from the dead. Layers of doubts are intertwined into a long-planned web.
In order to find out the cause of his father's death and uncover the truth of the past ten years, Guan Yu regained his tenacity as a criminal police officer and rushed to the dangerous appointment with clues from the old case. Is this rainy night meeting a trap or the entrance to the truth? What kind of evil is hidden behind the four mysterious surnames? Can Guan Yu find out the mastermind behind the scenes in the fog and seek justice for his father and Li Wei? An unsolved case that had been sealed for ten years was reopened in a heavy rain.
It's super nice. I hope it will be updated soon.
