Naruto System in One Piece - Chapter 390

A child was born unable to cultivate Inner Strength. In order to gain his father's attention and regard, he resolutely chose the painful and difficult path of cultivating Outer Strength. As spring gave way to autumn, time flew by, and the child grew up... he became a young man. What truly changed his destiny was a mysterious Crystal Stone formed from a meteor—the Meteor Tear. This Meteor Tear, unbeknownst to the young man, merged into his body, and like a caterpillar transforming into a butterfly, the young man metamorphosed... And with that transformation, everything changed. And his father finally came to realize the astonishing strength of the son he had never truly invested his Heart Power in...

After transmigrating into the Marvel-DC multiverse, he, once an ordinary person, has now become a world-renowned mercenary and assassin.Things have changed. Should he become a righteous hero, or continue his dark profession?“Don't use such shallow concepts like good and evil to judge me. I only do what I want.”Suddenly, the protagonist appeared behind the author of this synopsis, punched him, and sent him flying.“The truth is simple. I am the death knell that rings in everyone's ears!”

Go back to 2000.
