As a Celestial Dragon, Having Four Systems Is Only Reasonable

Yang Xuan transmigrates into the world of One Piece and becomes a mighty Celestial Dragon.

He also obtains the fortress Atlantis and unlocks four Systems.

Grind System! The Six Powers of the Marines? The complete version has thirty-six forms.

Pay-to-win System! There are only three Ancient Weapons? I've got twelve.

Lucky System! Devil Fruit users are freaks? Tell me what fruit you want and I'll find it for you.

Cheat System! Conqueror's Haki is one in a million? You've never seen Haki that can be seen with the naked eye.

So many weirdos have appeared on the seas lately!

Akainu: "A bounty hunter guild is training the Marines. I can finally close my eyes with a smile."

Doflamingo: "This guy, code-named Godfather, has stolen my entire arms business!"

Blackbeard: "Captain Jack, my lifelong rival!"

Shanks: "Why does a mere Bandit King keep refusing to show me any respect...?"

Imu: "Yang Xuan did all this by himself? We can't let him live!"

Well, the member nations of the World Government have all joined his maritime alliance.
