System + high intelligence + horror + infinite flow, one heroine.
Lin Mo, a criminal profiler, is bound to an Underworld System and forced to travel between supernatural instances set in modern cities and ancient villages. Each instance is built from the resentment of those who died unjustly: a girl in red haunts a school, while the old village chief's cult rituals continue in a desolate village. Lin Mo must use his extraordinary intelligence to solve a string of murders and find a way to survive as vengeful ghosts hunt him down.
He meets Su Wanqing, a coroner who can communicate with spirits, and Chen Mo, a police detective. The three form an unlikely alliance. Su Wanqing's supernatural senses and Lin Mo's rational deductions complement each other in subtle ways, while Chen Mo uses force to fight the horrors made flesh. The System keeps announcing a death countdown in its cold electronic voice, and the arrival of the mysterious Professor Shen Qingyuan seems to reveal a greater conspiracy behind the instances.
As ancient sacrificial rites and modern murder cases begin to resonate with each other, Lin Mo gradually realizes that the System is exploiting his desire to save the world. Walking the knife's edge between sanity and madness, he must not only help restless spirits pass on, but also uncover the truth about the System itself. Whose ritual is this deadly game, really?
