One Piece: The Strongest Creature in the Beasts Pirates

Luo Xing transmigrates into the world of pirates and gains a System that increases his defense. Whenever he takes damage, he gains defense points corresponding to how much damage he suffered.

Starting out with the Beasts Pirates in Wano Country, Luo Xing gradually sets out on the path to becoming the strongest.

"Come on, Yamato, hit me! Don't hold back!"

"Admiral Akainu, did you skip breakfast? Why is your magma so lukewarm?"

"Whitebeard, your Tremor-Tremor Fruit should be able to do more than that, right?"

Luo Xing keeps challenging powerful opponents. What drives them to despair is that the more they fight him, the stronger and tougher he gets. In the end, they can't even break his skin.

Teacher Kaido cries out, "Of everyone I've fought in terms of defense, no one is tougher than you. I, Kaido of the Beasts, proclaim you the Strongest Creature!"
