Reborn at Fifteen, Buried at Thirty-Two

Synopsis

Yan Hanu leads the world's strongest team into the final SSS dungeon wearing seven pieces of SSS-grade equipment. Inside the boss chamber, the tonic his own squad hands him turns out to be something else, and his gear falls off a body that has shrunk to fifteen years old. His companions walk out with his armour, his sword and his reputation, and tell the cameras that he died a hero. What they leave behind is a boy carrying a system that ignores rank limits entirely — and a high school selection exam that opens in the morning.
