Lin Chushi is a sophomore student in the History Department of Jiangcheng University. He has a gentle and taciturn personality and is often mistaken for a "weird". After an accidental fall from a building, he began to dream of Taoist priests in green robes, peach wood swords and blood spells - these were the memories of Mao Xiaofang, a descendant of Maoshan a hundred years ago. As the memory fragments revived, he found that he could see "the lingering ones": the souls of those who lingered in the world because of their obsessions. Bizarre deaths occurred one after another on campus. The school authorities blocked the news and the students were panicked. Lin Chushi reinterpreted Maoshan magic from a modern perspective, no longer blindly exorcising evil spirits and suppressing ghosts, but listening to the last wishes of the deceased and helping them resolve their knots. However, when he thought he was "transcending", the truth was reversed layer by layer - all the dead souls were actually related to an unsolved cause and effect in his previous life. In the end, he must face a cruel choice: cut off reincarnation, or fulfill his obsession?
