Hei Wu High School has a rumor that says, “Xie Gui (Evil Ghost) has the Book of Witchcraft and will use it to summon the demons in hell. His evil force will swallow every human. The only person who can stop him is the legendary nightwalker, Huo Lang (Fire Wolf).”

Knowing that Xie Gui has infiltrated Hei Wu High, Huo Lang quietly arrives at the school as well, right at a time when the school is experiencing a terror like no other. Series of online horror stories became a frightening reality inside Hei Wu High. According to intel, the author, Yuan Dian Ye Wu, is a student from this school. Is this connected to Xie Gui’s dark force?

The school is shrouded in terror until a new teacher, Ying Yan (Eagle Eye), shows up. Ying Yan’s parents died a year ago under the exact circumstance as described by one of Yuan Dian Ye Wu’s online horror stories. Because of that connection, he applies to be a Hei Wu teacher in order to catch the killer.

Yuan Dian Ye Wu’s real identity is Hei Wu High’s First Class honor student Yuan Sheng Wu. To others, he is like an angel. But inside, he is an evil monster. The only person who manages to avoid Yuan Dian Ye Wu’s fatal attacks is a mysterious Japanese transfer student named Dean. Combined that with a love triangle with X Class’s Yi Mao makes Yuan Sheng Wu’s fire of jealousy burn out of control.
