One Piece: The Jar Merchant

Ma Teng transmigrates into the world of the Pirate King and obtains a Lucky Jar System.

It’s a system that creates happiness with money.

The jars can produce any item from the Myriad Worlds. For every jar he sells, he gets a jar with ten times the drop rate.

The first world Ma Teng binds to is the world of Palworld, where anything from the game, including items and Pals, can be produced.

Pal Spheres can be used to catch Sea Kings, and even people.
