One Piece: Gambling to the Top (Rewrite)

Josh, a young man thrust into a perilous world where strength, agility, and cunning determine survival, discovers he possesses a mysterious system that grants him the ability to draw powerful rewards from a lottery-like game. With luck as unpredictable as the dangers that surround him, Josh must navigate a treacherous landscape of pirates, bounty hunters, and secret organisations. Each draw offers the potential for life-changing abilities, from strength-enhancing potions to mastery of deadly combat techniques, but with every gain comes new risks.

With danger lurking at every corner, Josh’s luck may be his greatest weapon—or his ultimate downfall. Will he be able to master his abilities, survive the deadly trials ahead, and carve out a place for himself in this world where the odds are stacked against him?

This is a rewrite of a fanfic by Blazuki. I do not own any of this content, be it from One Piece or Blazuki. I am posting this purely for entertainment's sake with no ulterior motives.
This OG fanfic is completed and has quite a high rating, which made me curious. After reading a few chapters, I realised that it's great, with its only downfall being a lack of editing (grammatical mistakes, wording in certain sentences, etc.). This is where I come in, with the task (given by yours truly) of rewriting the novel and adjusting it slightly by correcting any mistakes in grammar and 'sentence-structures' I notice.
Therefore, if you feel like contributing in any way, please refer to Blazuki's account (found his patreon link: www.patreon.com/Blazuki). All I'm doing is trying to make an already great fanfic just slightly better.
Please leave a review below or a comment in the chapters with some advice to help me do this work justice. This is my first time doing this sort of thing, so I welcome all the help I can get. Thank you and hope you enjoy.

PS: Again, the original creator is Blazuki, direct all the love to him.
