One Piece: I Devoured Lightning and Merged It with Flame, Then Handcrafted a Nuclear Bomb

Lin Yuan, a young man from the modern world, transmigrates into the world of One Piece in the flesh. He eats the Swim-Swim Fruit from the start, a fruit whose history has been erased, but is cursed by the sea and nearly drowns. Using modern knowledge to get ahead, he steals the Rumble-Rumble Fruit, produces electrolytic gases, and inherits the Flame-Flame Fruit. Water, lightning, and fire combine into something like a three-colored fire lotus! At the Paramount War, when a hydrogen bomb rises to illuminate Marineford, the whole world trembles! “Blackbeard, can your darkness swallow this?”
