Modern urban hard-core criminal investigation + pseudo-supernatural suspense reasoning, all "supernatural and strange things" are criminal disguises deliberately forged by the murderer. Shen Ci's special ability is not a metaphysical power, but the residual memories of the deceased, the remaining traces of crime, and the fragments of human obsession that ordinary people cannot capture.
Lu Zheng represents legal principles, evidence, procedural justice, and absolute materialism, while Shen Ci represents invisible traces, the truth about human nature, dead-end clues, and unconventional perspectives in solving crimes. The criminal police captain breaks the stereotype of criminal investigation, and the sleight-of-hand boy escapes from the shadow of the past and gets rid of the shackles of suspicion. From hostility and suspicion to mutual trust of orders, he becomes the only exclusive partner in the city bureau who can solve old mysteries, serial supernatural murders, and perfect unsolved crimes.
