One Piece: Starting with the Door-Door Fruit to Become the Master of Space

Lin Yuan, a physics PhD, wakes up to find himself transported to the world of One Piece.

He has no system, no cheat-only his knowledge of spatial physics and a Door-Door Fruit squandered by the body's original owner, Blueno.

While others are still struggling to master the Six Powers, he is already folding space with the Door-Door Fruit to teleport a thousand meters;

While the Marines are still chasing petty pirates, he has already raided a World Government transport ship and made off with a hundred tons of Seastone;

While the Rocks Pirates are still recruiting, he has already rescued Kaido and King from Punk Hazard.

"The true nature of the Door-Door Fruit isn't opening doors. It's spatial manipulation."

"I can go anywhere, and I can leave from anywhere."

"This isn't a support ability. It's a strategic-level power."

From defecting from the Marines to establishing Hachinosu, from winning Kaido's allegiance to befriending Whitebeard, Lin Yuan uses one spatial door after another to reshape the balance of an entire era.

The Celestial Dragons want to capture him? The Five Elders want to kill him? The Marine admirals want to hunt him down?

Lin Yuan merely smiles and draws a hand through the air.

"Catch me if you can."

This is the story of a spatial ability user who rises from the bottom, gathers the world's strongest fighters, and ultimately stands at the pinnacle of the world.

No pandering to canon characters, no following the original plot, and no relying on bloodline supremacy.

My fate is mine to command, not heaven's.
