Qin Lan awakens an F-grade talent in a world where college entrance exams become horror dungeons. When killed by monsters, he gains a one-minute rewind and permanent stat boosts. He repeatedly dies to farm attributes, rising from F-grade to a two-star hunter using a crowbar and sharp wit. He faces pursuit from the Qian Group and scrutiny from Lu Xingshan. After clearing the 5-star dungeon Final Destination, he wins a hidden job: substitute Reaper. He now prepares for the four-school joint exam.
