Sett, the overlord of Ionia's underground arena, accidentally fell into the world of pirates after a battle.
There is no devil fruit, no system golden finger, what he has is the steel and iron bones given by Vastayan blood, and the instinct tempered by ten years of gladiatorial combat - battlefield pride. The more damage you take, the harder your counterattack will be.
Starting from a dilapidated arena on Mosuo Island, he collected iron teeth, defeated poisonous scorpions, fought against the navy, and entered a new world. The golden fist flag of the Hao Fist Club is planted all over the sea, and the Shichibukai, the Four Emperors, and the Navy Headquarters all have to recognize his rules.
"I have the final say on this sea."
(Wu Yimu, I'm so awesome that I don't know how to fight)
