When supernatural incidents occur one after another on campus, three students are mysteriously unconscious, and Yun Shu, who has yin and yang eyes, becomes the next target. The mysterious exorcist Fu Yan appears as a trainee teacher and reveals the mystery of Yun Shu's life experience - he may be the son of the Yun family who disappeared twenty years ago.
The two were forced to join forces to investigate and found that a century-old evil spirit was sealed underground on campus. As the investigation deepened, Fu Yan discovered that Yun Shu could not only see spirits, but also possess the lost "blood talisman" ability of the Yun family. And Yun Shu's nightmare gradually reveals a shocking truth: his bond with Fu Yan is far deeper than imagined, and the incident twenty years ago has an ulterior connection with the massacre of the Yun family...
Concept: "In the eyes that see Yin and Yang and the hands that touch taboos, a bond deeper than a curse is born."
