One Piece: Fusion Barrett at the Beginning

The sniper king Haotian brought the Zanpakutō given by the system, which could be transformed into the Barrett sniper rifle, and his soul penetrated the body of the devil descendant Barrett, the strongest combatant in the Pirate King's fleet. From then on, he used the combination fruit and the Barrett Zanpakutō to start the road to invincibility until he became the invincible sniper god. Facing the attack of powerful enemies, he can easily punch Garp and Cyborg Kong, slash the swordsman Wu Laoxing, step on the flying golden lion, and shoot the strongest Whitebeard! This allowed him, who had repeatedly failed in challenges, to finally have the opportunity to defeat Roger, who was about to die of illness and be executed! He was 15 years old that year and challenged Roger the Pirate King many times, but always lost. Fortunately, he was able to draw with or even defeat Vice Captain Rayleigh, which was not too embarrassing! That year, red-haired Shanks and Clown Bucky were still 9-year-old little kids, playing pirate games in some corner. This novel and its characters are purely fictitious.
