Song Zhe set up a supernatural investigation team by chance. He originally wanted to make some small money, but he was involved in a supernatural mystery that spanned three generations. While solving the "Shadow Incident" that seemed absurd but actually deeply rooted in people's hearts, the team experienced various challenges such as evil ghosts seeking lives, people in the mirror whose authenticity is difficult to distinguish, and ghost market transactions where good and evil are mixed. Resolve crises through humorous exchanges, and grow among people, ghosts, desire and redemption. Each of the three volumes of stories has an independent main line, and finally converges on the ultimate mystery of the supernatural world - dissipation and existence. Where is the boundary between different worlds? After a battle spanning yin and yang, life and death, the members embraced life in their own ways, leaving behind memories of laughter and tears.
