Reincarnated in Ace's Body, I Break Out of Impel Down from the Start

Jin Yan's soul transmigrates into the world of One Piece, and through a stroke of bad luck, he becomes Gol D. Ace's twin brother.

From the start, he's already imprisoned in the underwater prison.

Fortunately, he obtains the King's System and begins to rise in every way:

Wealth, strength, power, fame...

Magellan: "He's the most brazen prisoner I've ever seen. No other prisoner has ever dared to escape right in front of me like that!"

Sengoku: "Akainu's death taught us a lesson. That guy really is terrifying!"

Kaido: "My Flying Six got beaten half to death by a restaurant waiter?"

The Five Elders: "A little boat for buying groceries, escorted by an Emperor's pirate crew and guarded by over a hundred rookie pirate crews? Who on earth is aboard that ship?"

Imu: "What? The Heavenly Tribute being sent in from all over is getting robbed one shipment after another? Who would dare do such a thing!"

Rayleigh: "He's surpassed Roger. The title of Pirate King of the new generation can only belong to him!!"
