Shen Yan, a psychiatrist, developed an investigative instinct after witnessing the mysterious death of her mother in childhood. In an accident, he awakened his "soul power" and was able to recall his soul memories at the time of the crime by touching objects at the crime scene. From then on, he intervened in serious police cases as a "non-staff consultant". From the corpse dismemberment case in the community to the ancient jade murder case in the museum, he used soul retrieval to solve seemingly perfect crimes. However, he gradually discovered that all the cases pointed to the truth behind his mother's death twenty years ago - a mysterious organization that controlled the "evil spirit contract". In the process of breaking the situation, his soul power advanced from the "spiritual vision realm" to the "spiritual realm", and finally launched a soul showdown with the mastermind behind the scenes, uncovering the mystery of good and evil that spanned two generations. The exciting rhythm of every case being reversed and every volume being upgraded runs through the entire text.
