"Weirdness" has arrived, with bloody words appearing on the blackboard, and students are forced to participate in "Quiz" and other games. Failure will be horrifically punished. Su Yuan and his classmates were involved. His classmate Mao Houwang was punished for not answering. He disappeared mysteriously and was forgotten by everyone except his classmates. Su Yuan took his sister Su Yuan (spirit body) and teamed up with his classmates to find evidence of Mao Houwang's existence, while completing the Blood Word Game to survive and trying to find "weird" flaws. Su Yuan discovered that school dormitory managers, security guards and other staff had been replaced by unruly young people. Is this related to the disappearance of Mao Houwang?
