In order to find his missing sister, biologist Lin Mo and the decadent detective Zhao Qian went to the strange ancient town of Zexu and accidentally unveiled the mystery of "Tai Sui", a high-dimensional life form. In order to prevent the disaster, Lin Mo was forced to coexist with Tai Sui's consciousness, struggling on the edge of humanity and alienation. This game around "symbiosis and erosion" spread from closed ancient towns to modern cities, eventually breaking through the boundaries of dimensions and pointing to the ultimate proposition related to the survival of multiple civilizations: When the shadow of high-dimensional collapse hangs over, and when the balance of chaos and order is at stake, can humans and aliens find a way to coexist across dimensions through understanding and compromise?
