Whitebeard Writes His Will: Ace Has Another Brother

Gol D. Nanfeng transmigrated into the world of One Piece and became the Pirate King's son.

When he was five, he unexpectedly awakened a Dungeon System and was forced to leave the world of One Piece.

He returned carrying the peak strength of the Naruto world.

But then he learned that his own little brother was already on the execution platform.

"So you're Akainu, huh? What does your beef with my brother have to do with me? Die!"

"Whitebeard? You actually made my brother your son while I was away? Let's fight!"

"Straw Hat brat, are you my brother's friend? Then from now on, you're my brother too."

"Blackbeard?! So you're the bastard who handed my brother over? Get over here and die!"

"Oh, isn't this young Zoro? Come on, use your sword moves on me. I'll show you what true sword intent is!"
