Pirate: the Strongest Sea Merchant King

I feel so wronged. I was originally a carefree rich second generation, and I just bought an island casually. But who would have thought that I would actually buy an island connected to the pirate world. I traveled here penniless and accidentally ate a devil fruit. I never thought that this ability could change the entire pirate world. "Old man, how can I get to the Navy Headquarters?" "You can take a boat from here and go around the Red Earth Continent." "By the way, young man, what are you going to do? Are you the man who wants to be the Pirate King?" "What do I do? I'm the man who wants to buy the Navy Headquarters!" "I am determined to be the Sea Merchant King!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
