One Piece: Playing as Magneto in the Beginning

I accidentally traveled to the world of One Piece, woke up and got the role-playing system, became a slave of a Celestial Dragon, and successfully extracted Magneto, the villain leader of the X-Men. At the same time, I can summon the abilities of my men to give to others. Let's see how the male protagonist starts a new era in One Piece. This is my first time writing. Please forgive me for any mistakes. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
