Simultaneous Transmigration: Why is it all One Piece world?

Noc is sick. Not just any sickness, but the legendary Duke Virus—a bizarre phenomenon that can split a soul and transport it across countless worlds! But why are all the Nocs transported to the world of One Piece?! And scattered across countless parallel universes. Each fragment, in a different parallel universe, at a different point in time, lives a completely different life. Sixty years ago, Noc became a giant, intending to kill Sister Carmel and recruit Linlin to his crew; fifty years ago, Noc unfortunately became a slave, his only motivation for survival being revenge; forty years ago, Noc became a Marine; thirty years ago, there was the Fish-Man Noc; twenty years ago, Noc struggled to survive under Orochi's oppression… until one day, the gears of fate began to turn. The Nocs reunited! The Duke Virus finally unleashed its power: the strongest abilities of all the Nocs are shared by all! The steel physique Nok gained at the cost of his life in the Navy, the unparalleled swordsmanship honed by Nok in Wano Country amidst mountains of corpses and seas of blood, the innate superhuman strength of Nok the Giant, the Armament Haki of Nok the Kuja, the Observation Haki honed to its peak by Nok of Whole Cake Island, and the Conqueror's Haki of Nok the Celestial Dragon who reigns supreme... Wait, what the heck is that slave Nok's ability? Hardening? Okay, that's not important. What's important is that even Devil Fruit abilities are shared! When Nok the Navy, having eaten the Rumble-Rumble Fruit, closes his eyes, lightning dances at Nok's fingertips; when Nok the Kuja devours the Float-Float Fruit, Nok the slave sends the Red Line flying into the sky! When countless "selves," countless strongest abilities, converge in one person, then only one question remains—in this world, who can be my enemy?
