Behind the bustling city there are countless fractures and intersections. The six protagonists, each living in different aspects of the city, are implicated in a series of technological changes and psychological weirdness. In the process of pursuing themselves, reversing their fate or escaping from difficulties, they continue to interact and influence each other. The main lines are both continuous and misaligned. Each volume focuses on one main line and interacts with other protagonists and branch lines. In the end, all the stories converge on the core event of the city's "crack", jointly revealing the mystery of the fission of urban psychology and social systems.
