My Class Is Too Useless? I Became a Walking Horror in the Dungeon

[Dungeons] + [Rule Horror] + [The Strange Immortal] + [Clever, Satisfying Story] That night in our middle school dorm, a pair of eerie red dancing shoes crushed my friend Chu Tianxiong's head, yet spared everyone else. Over the next three years, my dormmates' brains kept exploding one after another. They seemed to have been killed by whoever was behind the red shoes. Only Zhang Jiuqing and I, Li Ye, managed to survive. Maybe one of us would be the next target. Then, one day, Li Ye received a mysterious package. It was sent by Chu Tianxiong, who had been dead for three years... Inside the package was a class card granting access to a dungeon. That same day, an official organization came knocking! Li Ye: "Who do you think those red dancing shoes will target next, you or me? Zhang Jiuqing, are you scared? The enemy lurking in the shadows is probably at least a Level 3 Walker!" Zhang Jiuqing scoffed. "All heretics will be destroyed. I will judge every last sin. That's my answer!" "Big talk! Good thing I feel the same way!"
