Lin Shen, a folklore graduate student at City University, moved into the old neighborhood of Huaian Road, which is rumored to be the most haunted, in order to complete his graduation thesis "Textual Research on Supernatural Legends in Old Towns." There are many ancient houses here and the atmosphere is gloomy. Bizarre legends such as "the ghost in the mirror", "the sound of hair being combed in the middle of the night" and "the missing tenant" are spread here. On the first night of his stay, Lin Shen encountered strange events: the door locked automatically, a strange black figure appeared in the mirror, and the sound of ownerless footsteps came from the corridor. As the investigation deepens, he discovers that behind every supernatural rumor, there is an old case that has been deliberately covered up - the missing female student, the tragic death of the housekeeper, and the craftsman who was buried alive. And the source of all this points to the cursed "Lin Family Old House" deep in the block. Not only did Lin Shen have to face the ensuing supernatural attacks, but he also had to beware of someone in the dark obstructing the investigation. He was even more shocked to discover that his family was inextricably linked to the Lin family's old home, and his arrival had already been written into a revenge curse that spanned a century. With the help of Su Wan, a girl who can see ghosts, Lin Shen peeled off the cocoon and explored the truth at the edge of the Yin and Yang worlds, finally uncovering the darkness of human nature and centuries-old grudges behind the curse.
