KO One: The Toughest High School Student in History

A young man transmigrates into KO One and becomes Luo Xiu, Huyan Jueluo Xiu's clone in the Golden Dimension. He also possesses a special constitution that lets him store the attack energy his body can withstand, convert it into protective aura, and reflect it back at his opponents.

Wang Dadong: "Hey, does this guy have some special constitution that gets stronger against stronger opponents? Why does he get stronger the more we fight?"

Wang Arthur: "How can he be even more demonic than I was when I removed the Sword Lock Stone?"

Ding Xiaoyu: "Impossible! My right fist is completely useless against him?"

Rex: "He can actually withstand an attack from the Hand of Ares?"

Cai Yunhan, Cai Wuxiong, and Lei Ting: "How is this guy's body so hard?"

Black Dragon: "This kid's seriously strange. Why don't you come work for me? I'll turn you into the strongest Corpse Warrior!"

The strongest? Sorry, not interested. My goal is to become the hardest man alive!

The hardest high school student in history is born at this very moment!
