I Am the God of Thunder on Rocks' Ship

Maxwell transmigrates to the world of One Piece during the Rocks era, starting out in the most hopeless situation imaginable.

Fortunately, he awakens a Challenge System. As long as he keeps defeating opponents in challenges, he can earn rewards.

The stronger his opponents become, the more abilities and items he obtains.

Want to know about the Rumble-Rumble Fruit?

A Door Anywhere for traveling wherever he likes.

And of course, the all-purpose capsules are a must-have.

Meteor-Falling Blade? Have you ever seen a meteor blazing with lightning fall from the sky?

Demon Sword... controlled by his thoughts, he can ride it through the air.

As Maxwell displays one incredible ability and item after another, the world is left in shock.

So Rocks isn't the terrifying one after all. It's Maxwell?
