At the Grand Line: Open a Can and Get Stronger

After an unexpected trip to the world of One Piece, Lin Ruohua awakened the Jar-Opening System... and began his career selling jars.

Zoro: "Shopkeeper, can I really bring Kuina back to life?"

Shopkeeper: "Of course. And that's not all: the items inside the jars can help you claim the throne of 'World's Greatest Swordsman.'"

Empress: "Can you really completely wipe out the Celestial Dragons?"

Shopkeeper: "No, no, I can't do that. But you can. The jars do contain ways to commit genocide..."

In the world of One Piece, Lin Ruohua opened a wish-granting shop that sold nothing but jars. Every jar held something magical.

Devil Fruits, kekkei genkai, magic, secret techniques: you name it.
