One Piece: Investing In Whitebeard At The Start.

In the volatile, power-driven world of One Piece, where pirates and Marines clash and the World Government reigns supreme, a weak orphan survived fifteen years by wit alone in lawless islands. Sold into slavery, despair loomed until a "Ding!" heralded the activation of an Investment System. This system offered the chance to invest in power. The protagonist's first crucial investment was in Edward Newgate, Whitebeard, the Strongest Man in the World, instantly granting the Tremor-Tremor Fruit. This was merely the start of a strategic accumulation of legendary powers, from Ryujin Jakka's flames to the Ice Age's freezing breath, by investing in those who already possessed Devil Fruits. Choosing assets wisely—strength, speed, techniques, regeneration, and Haki—the protagonist eschewed personal Devil Fruits for a growing portfolio, earning scorn from pirates, fear from Marines, and the ire of the World Government. While others train for decades or raise armies, the protagonist "clicks and conquers." The goal is not just the One Piece, but absolute dominion, aiming to become the world's strongest, richest, and most dangerous, ensuring their name is etched into the sea's history.
