Campus Restricted Area Rules

When the late-night campus radio begins to read out incomprehensible rules of survival, the peaceful university campus turns into a strange hunting ground. The crying girl in a red dress, the non-existent reading room, the knocking sound of the toilet at midnight, the forbidden basement... Behind every rule lurks a "weird story" that longs to be obeyed, or preys on violators. Li Zhe, an ordinary college student, was forced to step into this restricted area with intertwined rules in order to find his missing roommate. He soon discovered that some rules are protection, some rules are traps, and the deepest terror stems from the ultimate rule - "We are all here to protect." Protect what? And who exactly are "we"?
