Zhou Xiaodai and five like-minded friends formed a night walking group of six. They originally just wanted to find excitement in a peaceful urban life, but they accidentally got involved in a series of incredible supernatural events. They interacted with the dark world in a relaxed and joking manner, and gradually grew up amidst various unsolved mysteries and extremely terrifying events. Each volume unfolds an independent supernatural adventure, with its own theme and climax, but also runs through the main line: the mystery of the father's disappearance, the secrets and growth of the team members, and the interface between the supernatural and reality. The book adopts humor and tight rhythm, with constant climaxes. In the end, the six people work together to solve all the mysteries. Their friendship and self-esteem are sublimated, and the story ends.
