Transmigrating as a Celestial Dragon? Laying Plans for a Hundred Years from the Start

[Blank Century plot + Imu as his underling + Master of the Empty Throne + multiple heroines]

After transmigrating into the world of One Piece, he discovers that he has become the king of the Nerona Kingdom.

At this point, Imu, the one pulling the strings behind the scenes, is still his loyal underling. He also has a silver-haired, red-eyed maid who obeys his every command.

During that hidden stretch of history, he marries Lily, the first queen of Alabasta, and manipulates Joy Boy as if he were putty in his hands.

Then, for various reasons,

by a twist of fate, he returns to the Great Pirate Era with a System panel and three beginner's gift packs.

Imu: “Big brother is the beacon of my life, showing me the way forward!”

Lily: “You are my salvation, my one and only!”

Red-Haired Shanks: “It's as if this guy can see everyone's fate!”

Mihawk: “I hereby declare you the world's greatest swordsman!”

Above heaven and earth, I alone reign supreme!

After all, long ago, people knelt before me and called me... “King”!

The World Government's eight hundred years of accumulated power now reside within me.

This one sword strike carries eight hundred years of history and power.

Can you withstand it?!
