Mr. Lin seems to be an ordinary person, but at night, he can become amazing. The little policeman who has no sense of presence in the county or town is a master at solving crimes at night. Could it be a coincidence that these two extraordinary people met in the darkest night of the city? A series of inconspicuous cases, the clues all point to the "ordinary" Mr. Lin, so is their meeting really lucky? Mr. Lin said: "The people living on the other side of the city are all devils. Don't try to save them. If you make a mistake, you will fall into the abyss."
Concept: Everything has two sides. Just because we live in the sunshine does not mean that there is no dark side.
