Have Fun in One Piece

(Don't worry, it's definitely not a stupid article) Traveled through One Piece and became a noble of a small country in the North Sea. At the age of eighteen, he obtained the superhuman radiation fruit. At the age of twenty-three, he became the new pinnacle of the North Sea. The "Blue Skull" Cardrans of the North Sea has a bounty of 280 million. When he kills someone, his bones glow green. He accepted the World Government's recruitment to become a Shichibukai, not for power, but to enter the new world with integrity and let people all over the world enjoy radiation. After seventeen years of traveling through time, he has perfected his physical skills and mastery, and the radiation fruits have developed into his bones. From the defecting nobles of the Kingdom of Ravana to the cold-faced murderer on the seat of the Shichibukai, Kaderans only believes in one thing: In this sea, there is a shared future! When the pirate's butcher knife is raised, he wants everyone to know that the law of "Blue Skull" is closer to death than any justice. In the year 1518 of the Hainan calendar, there are still two years before Luffy goes to sea. The legend of "Blue Skull" has just begun. (There are no system plug-ins. The protagonist only relies on fruit abilities and physical skills. This is not a brainless novel, starting with the Shichibukai.)
