Criminal Investigation Record: Mysterious Cases in Fog City

Ten years of fog, an undercurrent in a city. Some people venture into danger alone and tear down the dark barriers with their obsession; some people stick to their original intentions and protect justice in the world with the law. The serial layout that spanned several years and the secret dark network disguised in layers revealed its flaws after a fire. Clues are connected layer by layer, confessions are broken step by step, and the hidden manipulator gradually emerges. When Gu Yong encounters the rules, when obsession returns to legal principles, above the foggy city, the haze will dissipate, and the truth will eventually be revealed to the world.
