Lin'an County, a small county surrounded by mountains and rivers, seems peaceful and peaceful, but in fact strange crimes occur frequently. The county town is built on the mountain. There are ancient tombs in the mountains, old houses in the city, and shipwrecks in the water. There are indescribable weirdness everywhere. The county government is not a big one, with less than twenty people including the chief clerk, the bookkeeper, the editor, and the police officer. Solving the case depends on boldness and carefulness... And a woman in red who can never get rid of him.
