Civilian Investigation Bureau: Section 3

In the Third Section of the Civilian Investigation Bureau, there is a piece of yellowed paper taped to the door of the archives room, with a line of handwritten words: "What common sense cannot explain belongs to us." 1987, Midsummer. At No. 7 Huaishu Lane, a female worker committed suicide by hanging from a beam. There was no stepping stone at the scene. There was only one sentence in the suicide note: There is a rope under the locust tree. When Chen Mo took the file bag, he didn't know what was underneath this case. It will drag the entire third division into an underground river called "Red Rust". Nine old cases, dusty for ten years, and a general file that has never been revealed to anyone. And a person who shouldn't exist.
