Anime Crossover: Infinite Item Upgrades, Starting with One Piece

Lin Yuan transmigrates into the world of pirates and gains the ability to upgrade objects.

After struggling his way forward, he discovers that all the Devil Fruits belong to someone else, so he can only develop an island and become a small-time island lord.

As it happens, Luffy’s grandfather is still a lieutenant, Shanks’s father is still young, and the God Valley Incident is still a long way off. Lin Yuan plans to build up his strength for decades before fighting alongside the Straw Hats.

But who could have imagined that his little island would grow better and better? Not only is it rolling in wealth, but one promising subordinate after another comes knocking. Before long, a powerful force emerges in the world of pirates. It rules the East Blue, rules the Grand Line, and now plans to rule the New World and take down the Celestial Dragons.

[You upgraded the island. Let’s hold next year’s Olympics on Naruto Island!]

[You upgraded ???. A terrifying, indescribable presence blots out the sky!]

With Lin Yuan around, the world of pirates has become incredibly exciting.

The Five Elders are on high alert, and Im doesn’t dare emerge from behind the scenes.

Whitebeard takes Lin Yuan as his goal, while the Okama King eats the Azure Dragon Fruit.

Across the Myriad Worlds, reaching the Emperor level is not the end!
