One Piece: The Navy's Sharpshooter with the Rumble-Rumble Fruit

Note: For the sake of the story, not everything will necessarily follow the original. If you don’t like it, feel free to skip it.

Lin Feng is a 17-year-old student from the modern world. One ordinary afternoon after school, he loses focus for a moment and gets hit by a car. His soul unexpectedly transmigrates and takes over the body of a boy named Ling-Hailan.

Ling-Hailan had been sailing out to sea with his parents to do business when they encountered a terrifying whirlpool in a sky-high ocean current. In the chaos, he was separated from his parents, whose whereabouts remain unknown. Their chances of survival seem slim. Ling-Hailan himself is swept by the raging current to the sky island above Gaya Island, where a kindhearted person rescues him.

To survive in this turbulent, chaotic world and gain enough strength to protect himself, Ling-Hailan struggles to find the Rumble-Rumble Fruit and resolutely eats it. He then chooses to join the Marines, carefully concealing the fact that he is a Logia-type Rumble-Rumble Fruit user. Keeping a low profile, he hides his strength and serves as a sniper in the rear, quietly building his power so he can eventually find his footing in this unpredictable world.
