[No heroine + supernatural horror + laid-back protagonist + absurd comedy + no romance + dungeon instances]
On the first day of the new semester, the supernatural returned. The school gates slammed shut, trapping everyone on campus. The students and the supernatural creatures outwitted each other, and the winners ruled over the creatures while the losers became creatures themselves. To survive, you had to remember the rules. Qi Tian had always had a terrible memory, but he was lucky. On the first day of military training, he was the instructor. On the second, he was the dorm supervisor checking access cards. On the third, he was the counselor introducing the teachers. On the fourth, he was the librarian fighting for a seat. He was an NPC in every dungeon, yet he held the protagonist's script.
