The protagonist, Chen Ye, was originally an ordinary criminal policeman. Due to a near-death accident, his left eye accidentally acquired the ability of "uncanny pupil". He can see "foul gas" (energy traces left by ghosts) invisible to ordinary people, have limited communication with whispering ghosts, and can even briefly inhale "foul gas" into his body to simulate fragments of memories or feelings of the deceased before his death, but he will bear huge mental pollution and physical burden. This is the core golden finger of his "case solving".
World background: The seemingly peaceful modern city is secretly filled with strange events caused by grievances, obsessions, and sorcery. There is an extremely secretive ancient organization "Scavenger", which is responsible for handling such incidents and maintaining the fragile balance between Yin and Yang. During his exploration, Chen Ye gradually came into contact with and became involved in the disputes of this organization.
