Lin Mo, an overworked corporate drone, is pulled into a survival game in another dimension by a scarlet invitation. Alongside strangers, he travels through scenarios such as a silent sanatorium, a town trapped in a time loop, and a maze of mirrors. Each setting taps into humanity’s deepest fears, and survival depends entirely on following rules concealing deadly traps.
On the brink of death, Lin Mo meets Su Qing and others, witnesses betrayal and sacrifice, and gradually discovers that the “rules” are part of a selection experiment by a higher-dimensional civilization that feeds on fear. They go from following the rules to survive, to searching for loopholes, and ultimately confronting the source of their fear. This is not only a battle for survival, but also a struggle against oneself. Only by accepting the vulnerability within can they break free of the rules’ chains.
