One Piece: Legend of the Navy King

[This book may be finished, and there may be a fourth volume to return to the One Piece fic. Regardless of whether I write it or not, I am already planning to write the next book. I will absorb the lessons learned this time and continue to improve.] [The first volume is a One Piece fic, the second volume is a Bleach fic, and the third volume is tentatively set in the fairy world] No heroine + ruthless and decisive methods + humorous elements. Another work after the Legend of Whitebeard, returning to the pirate path. Sakaski received system assistance, and later took the form of a green dragon, a phantom beast from the Fish Fruit. His ambitions grew a hundredfold and he decided to end the era. It won't be like some groups who have excessive preference for comic characters, so you can read it with confidence.
