When Liu Wentian received his acceptance letter from Ivy University, he was filled with anticipation. But the moment he stepped onto campus, the “school rules” carved into a stone tablet left him sweating with fear: Run three laps around the clock tower every morning, and if someone calls your name from behind, never turn around; don’t enter the east corridor on the third floor of the dormitory late at night, and if you wander in by mistake, close your eyes and count to thirty; and whatever you do, don’t even look at the free soup in the cafeteria on Wednesdays... One student refused to believe the warnings and vanished without a trace after breaking a rule. Liu Wentian realized this wasn’t a university, but a cage of rules that devoured people. He must survive by obeying these deadly rules, or finding ways around them, while uncovering the truth behind Ivy University’s rule-based murders. He also hopes to become the first “rule-breaker” brave enough to challenge them.
