One Piece: The Pirate King? I’m the God of a New Era

[The real deal: pirates] [Multiple heroines] [Devil Fruit] [System] Note: The protagonist is a selfish pirate, not a saint. He will neither save the world nor destroy it. He'll simply climb step by step to the top of the world and look down on all of humanity. Note: The story focuses mainly on developing Devil Fruit powers and training in the sword. The System is secondary. Ye Feng transmigrates into Pirate King and, from the start, obtains the Zoan-type Human-Human Fruit, Mythical Zoan, Vajra Guardian Form. The Vajra Guardian is the highest protector deity in Buddhism. Not only is he incomparably strong, he can also summon the power of all the Buddhas. When the Vajra Guardian appears, all Buddhas clear the way and all gods stand aside. His life takes off in an instant. He also receives the Indestructible Vajra Divine Art from the start. Once mastered, it makes him deathless and impervious to destruction. Ye Feng can only say: “Badass.” The Four Emperors? Marine Admirals? Nika? Imu? Joy Boy? Ye Feng can only say: “They're all trash.” This is my era, Ye Feng's era, the era of the Demon Lord. Before me, you have only two choices: kneel and die, or kneel and live.
