Pirates, Conquering All Worlds Starting from the East China Sea

Traveling to the world of One Piece is just before the plot begins. This year, the great pirate era was at its peak, the throne of the Celestial Dragons was as stable as Mount Tai, but the destined savior had not yet eaten the fruit that had been waiting for him for eight hundred years. Facing this strange era, Xia Ya, who owns the portal, decided to endure it. At first, he just wanted to use the navy's skin in the East China Sea to develop his own power to help him explore the world. But slowly, things went beyond his expectation... "Under Char's leadership, we will end the evil rule of the Celestial Dragons! Let fairness and justice truly come to this world." Seeing the three ASL brothers in general uniforms declaring war on the Tianlong people in a live broadcast to the whole world, and Garp behind them who was as happy as a fool, Char was completely dumbfounded. How did I come up with a new navy? (The world to be conquered: Campus Apocalypse, World War Z, Demon Slayer: Kimetsu no Yaiba)
