Became the Richest Man on the Grand Line

Xia Ye is a child that Maginot picked up in Xia Ye. From then on, he was called Xia Ye. Xia Ye has lived in a small windmill village since he was a child. He didn't have many friends to begin with. When the only few friends in the village went to sea one after another, Xia Ye became completely irritable and wanted to go to sea too! But because he didn't have a navigator, the ship ended up deviating from its course and arriving at various strange islands—— The first island was called Hawaii, where he met a friend named Kudo Shinichi. This friend's ability was so powerful... The second island was a very prosperous port city, and he used the things here to exchange for many things he had never seen before... There was a very backward ninja village on the third island, so he was (forced to) sell to them the things he had exchanged on the previous island... … In the end, Xia Ye looked at Bailey in front of him and wondered why he made so much money...
