Revolutionary Army from the Start: Marrying Robin and Having Luffy as My Son

Li Moyi unexpectedly obtains the Main God System and becomes a world-hopping traveler.

In the first world, he's the greatest demon slayer!

In the second world, he's the greatest ninja.

In the third world, he becomes Monkey D. Dragon!

On my first day here, Garp called and asked me to rescue Ace?!

On my second day, I plucked Nico Robin out of the sky!

Under the System's mission, Li Moyi decides to join the Paramount War!

Sengoku: "Garp!!! Fine, your grandson is here, but why is your son here too?"

Garp: "Dragon, you're here to cause trouble, aren't you? Take your people and get out of here, now!"

Kizaru: "This man... is so scary!"

Nico Robin: "Being by his side and joining the revolutionary tide might not be such a bad thing, would it?"
