When he received the admission notice from Ivy League University, Liu Wentian was filled with admiration. But as soon as he entered the campus, he was frightened into a cold sweat by the "school rules" engraved on the stone tablet - he had to go around the bell tower three times in the morning jog, and never look back if someone shouted from behind; do not enter the east corridor of the third floor of the dormitory late at night. If you entered by mistake, you had to close your eyes and count for thirty seconds; you could not even look at the free soup in the cafeteria on Wednesday... Some students did not believe in evil and disappeared without a trace in an instant after breaking the rules. Liu Wentian understood that this was not a university, but a prison with rules for cannibalism. He has to live by abiding by (or exploiting loopholes) these deadly rules, while finding out the truth about Ivy League University's use of rules to kill people, and becoming the first "rebel" to dare to challenge the rules.
