Legend has it that somewhere along the Grand Line, there's a restaurant called the Peaceful Restaurant.
Its owner works as a deliveryman. They say that no matter who you've offended, once you step inside the Peaceful Restaurant, you won't be hunted down, whether by pirates, the Marines, or even the Revolutionary Army.
They also say that, on top of inheriting the powers of the strongest king, this deliveryman's strength is enough to maintain peace in the pirate world.
"Hawk-Eye, are you the world's greatest swordsman?"
"No. Su Xing beat me to a pulp."
"Whitebeard, are you the world's strongest man?"
"No. Su Xing is the strongest man in the world."
"Empress, you're the most arrogant woman in the world."
"No. In front of Su Xing, I'm as gentle as a kitten."
"Kaido, you're the most violent creature in the world."
"No. Su Xing says he'll make me the world's most impotent creature one day."
P.S. The strongest delivery king, the strongest Magic Box System...
