A bizarre murder occurred in a haunted house on a rainy night, and the tragic circumstances of the deceased were exactly the same as those of the unsolved case ten years ago. {Jiang Ce}, an "idler" who hangs out at the bottom of the city, has a golden finger that can see through the yin and yang - he can see the "afterimage of death" at the crime scene. He is as sinister as a fox and as strategist as the abyss. He never ends up personally involved. With just a few words of advice, he lets the police clear up the confusion.
Strange serial murders followed one after another: strange footsteps in the corridor at midnight, strange faces appearing in the mirror, bloody spells left by the missing persons... Behind each case, there are mysterious secrets that have been shrouded in dust. Jiang Ce worked step by step, using the afterimage fragments to piece together the truth, but found that he had already been involved in a huge conspiracy that spanned the realms of Yin and Yang.
When the black hand in the shadow gradually surfaced, he realized that the so-called golden finger was always a bait with thorns. In this game, either the overall situation is controlled or it is doomed.
