Jiang Yanchuan, the Seventh Prince of the Great Sheng Dynasty, is transported by a system into an infinite-flow survival game. His brocade robe turns into a school uniform, and the only people left by his side are his maid, Lin Qiyue, and high school student Xu Ye. In a white space, he faces three difficulty levels. Thinking the red button looks appealing, he casually presses the Hell-level option—the only level that preserves memories. Their first stop is a werewolf school, where the entire student body has turned into wolves, yet the school bell still rings as usual: students mop floors on cleaning duty, administrators check ID cards, and everyone queues in the cafeteria. The prince applies ancient rules to a modern school, treating queues like military formations and ID checks as official duties. With a casual remark, "This prince shall give it something," he stuffs a fire extinguisher into a monster's lunch tray. Once a monster spots you, you have four beats left to live. The instance resets, talents are wiped clean, and only memories remain.
