Su Dong accidentally entered a supernatural company and formed a "spy detective team" with his master Lao Lu, photographer Lin Xiaomeng, the underworld messenger Ali and his eccentric colleague Boss Huang. They unraveled the frequent strange events in the city and gradually came into contact with the conspiracy of the three realms: the recovery of the secluded city, the reversal of the soul lock, and the shaky order of the human and ghost realms. With every thrill, the trust, friendship and growth among the team members are tested. In the end, Su Dong had to make the biggest choice between warmth and justice, reality and the spiritual world, resisting the dark forces with humor, passion and warmth, and sublimating self-salvation and mutual bonds. The three volumes of stories are intertwined with each other, the rhythm is tight, the cases have ups and downs, comedy and horror are intertwined, and finally it ends with a climactic decisive battle and a warm ending.
