Chen Mo was originally an outer disciple of the Qingyun Dao Sect. Because he uncovered the secret of the elder's collusion with the devil, he was falsely accused of stealing the sect's treasure and abolishing his cultivation. He was expelled from the sect and became a useless person. When he was dying, he accidentally activated the [Yin Yang Achievement System]. This system can earn merit points through actions such as "slaying demons and demons", "solving unsolved cases", and "supporting justice". Merit points can be used to repair one's cultivation, exchange for god-level skills, magic weapons and talismans, and even unlock magical powers such as the "Eye of Insight".
In the early days, Chen Mo lived in seclusion in the market, starting from solving trivial "evil troubles" among his neighbors, gradually accumulating merit and regaining his strength. In the process, he got acquainted with Su Qingying, a cold girl with a mysterious identity who is good at paper-piercing. The two of them tested each other and cooperated to solve a series of difficult supernatural events, such as "Painted Skin Bride", "Yellow Skinned Man Seeking Seal", "Water Ghost Pulling Cart", etc.
