The Mightiest Leveling System - Chapter 6

Traveling through the world of pirates, becoming Luffy, and possessing cheats in teaching space, it is natural to make changes.

When Chambord landed on the island, the pacifist, the general Huang Yuan, appeared, and all the supernovas fell into despair except the hat group.

Seeing Zoro sweeping the world with a single sword, Sanji the Demon Kazekaku, and Luffy blasting away the oracle with his four-speed karma fist gun, the supernovas were stunned.

“Is this a supernova? I’m afraid it’s not the imperial group!”

During the war on the top, the hat regiment descended with the momentum like a royal regiment.

On Ghost Island, Kaido and Big Mom satirized: “Hey, boy, what are you going to become? Say it again in front of us!”

Luffy opened five gears furiously, his fist was as huge as a ghost island! A five-speed Yehuo fist gun! Party Kaido and Big Mom!

Luffy landed, the black stand-up collar cloak fluttered, put on the helmet, and whispered domineeringly:

“I’m Monkey d Luffy, the man who wants to surpass you and become the One Piece!”

In a morgue filled with the bodies of Uchiha clan members, he opened his eyes...A mysterious voice echoed in his ears...With a bewildered expression, he muttered, “Save the Shinobi world? What does that have to do with me, a mere Uchiha survivor?”

I gave them my everything.My time… my strength… my heart.I trained while they slept.I smiled when they laughed.I stayed… even when it hurt.And what did I get?Nothing.They looked at me like I was pathetic.Like, I didn’t belong.Like I was… less.But I... the naive person I am, continued trusting them.They told me to act like trash, fine—I became trash.They told me to act like a scumbag, fine—I played the role.However...One mistake, one single moment...That’s all it took.And they threw me away.But now…Someone else woke up in my body.A stranger, a man who doesn’t know the pain I suffered, but wears my face.Let’s see what he does with it.Because me?I’m done with this life, so to the soul who took over my body...This is your mess now…'Gray'.
