In the rain curtain of Silver Moon City, the snake-moon symbol is entwining old cases like a ghost. Former police officer Lin Yu, self-media blogger Su Yao, and crime team leader Chen Feng were forced to join forces due to the mysterious death of Zhou Mingyuan. They uncovered the secrets of the ancient book restoration shop, the mechanisms of the ancient tomb, and the undercurrent of the police station. Not only did they have to uncover the truth about the tragedy of the archaeological team thirty years ago, but they also had to fight against the mysterious forces hidden behind the scenes. Everyone's past was closely connected to this half-life conspiracy.
