Lingxi, a sophomore at Jinghu University, appears to be an ordinary beauty who is worried about her high-level math class, but secretly she is the last descendant of the Xuanmen family. She works part-time as a "spirit-wading person". To put it bluntly, she is a "worker in the underworld" who helps "relevant departments" deal with the ghosts stranded in the upper world.
She was born with yin and yang eyes, and could see monsters and monsters that ordinary people could not see. She had a special constitution and her soul was as pure as a walking "ghost magnet", but this also forced her to learn mystical arts to protect herself since she was a child. During the day, she discusses celebrity gossip with her roommates and copes with rigorous professional courses; late at night, when the mysterious APP on her phone rings, she has to change into clothes that are easy to move around and deal with various ghosts lingering in the world due to obsessions: it may be a rich girl who refuses to accept the reality after a drunk driving death, it may be a person who died unjustly, or it may be a little ghost who is simply lost.
On one side is the youthful daily life of college students, on the other side is the supernatural world dealing with life and death, obsession, and cause and effect. Between her studies and "part-time job", Lingxi not only has to deal with all kinds of ghosts, but also has to solve the mystery of her life experience - why did her parents disappear mysteriously? What is the Taoist secret that grandma keeps? And behind those seemingly independent supernatural events, there seems to be a hidden thread connecting the past and the present...
This is a story about growth, responsibility and redemption. It includes the thrills of catching ghosts, the delicate thoughts of adolescence, and the discussion of life, death and human nature. When a beautiful girl encounters "dirty things", let's see how she makes her own way between the worlds of yin and yang.
