I got transmigrated into World of One Piece, but no system?

Warning: The story is exceedingly dark and contains explicit mature and gore scenes. [ If you want realistic One Piece Fanfiction with a clear plot and character development, rather than wish fulfillment with random plots and various trash characters who appear out of nowhere, read my Fanfiction ] [ Are you tired of reading Fanfiction with a system full of statuses, skills, points, shops, gacha, cheats, and other bullshit that interferes with the story? Don't worry. As the title suggests, this Fanfiction has no such thing as a system, so the MC must rely solely on his own strength from the start ] [ Are you tired of the main character who disregards his priorities and instead becomes naive, ignorant, unreliable, and a whiny child who constantly complains? You don't have to be worried because the MC in my Fanfiction doesn't have that annoying trait ] [ Are you tired of Fanfiction with messy, unclear, cringe-worthy, unreadable, strange, and random plots? You can try reading my Fanfiction because I try my hardest to make the plot with full calculation, twists, and, most importantly, make sense to read ] [ Finally, do you want an One Piece Fanfiction with smut, romance, explicit adult scenes, and well-explained emotional relationships? You can read my Fanfiction because I write and create each character with detail and care, so there will be no copy-paste or flat characters ] I have a Patreon where I post many NSFW illustrations of various fanfiction characters I've created, and you can also get access to 20+ early chapters ahead of time; your support is greatly appreciated. patre0n.com/Instamoist
