One Piece Black Market

Yashin transmigrated into the One Piece world without any system or with exceptional powers. But fortunately he kept his intelligence and memories. *** It won't be a story where the MC beats everyone and is invincible. He will rather make his life smart and will not provoke a lot of people at the beginning. But when his traffic gets bigger he will start to become more powerful. I hope you enjoy this story. I tried to make an original story while respecting the rules of the One Piece world.
