One Piece Stories Set in the Same Era as Rocks

One Piece fan fiction set in the same era as Rocks. Please, all you experts, grant me some books.

Looking for One Piece Stories Where the Protagonist Joins the Navy and Becomes Its Strongest Fighter

There must not be any plotline where pirates join the pirate faction.

One Piece: Unmatched Combat Power, Peak Martial Arts, and Awakened Devil Fruit

Looking for books similar to One-Yuan Instant Kill: From the Start, I Get Red-Haired Shanks' Conqueror's Haki! (The Age of Devil Fruits for All).

One Piece Navy Stories: Join the Marines, Be at Least Vice Admiral Level from the Start, and 300,000+ Words

The Male Lead Is a Pirate From the Same Era as Rocks, and Later Becomes One of the Four Emperors

The protagonist eats a Devil Fruit and builds their own faction. Logia, Mythical Zoan, or Paramecia. Ideally, the male lead eats the Dark-Dark Fruit.
