One Piece: From the Start, Planetary Devastation Leaves Sengoku Stunned

[Pirate King + Gravity Fruit + Ancient Weapon + Invincible Protagonist] On the verge of death the moment he transmigrates? He swallows a divine-grade Gravity Fruit and immediately comes back to full health, with his power through the roof! His talent awakens, and the matching Ancient Weapon “Abyssal Calamity” recognizes him as its master. Just how incredible is this beginner’s gift package? The pirates are acting arrogant? One move wipes out the whole crew, leaving no trace! The Marines are acting superior? One kick smashes a naval harbor and leaves everyone speechless! I, Ryan, am the most arrogant rookie in Marines history, and the strongest rookie, too! They call me a monster, a madman, an uncontrollable weapon. They’re all right! When the Ancient Weapon “Abyssal Calamity” fully awakens in my hands, the entire world will tremble and submit beneath my gravity!
