A Kingdom Rises in the World of One Piece

Protagonist: Yi Feng, an ordinary young man from Earth before he transmigrates. He knows the plot of One Piece inside out, is rational and level-headed, has ambition and principles, and values his companions and his people.

System: Overlord Cultivation System

Core features: Complete quests (main, side, and hidden) to earn attribute points, skill books, Devil Fruit fragments, Haki insights, and special items.

Support features: Attribute panel (strength, speed, defense, mental power, Haki proficiency), skill library, storage space, and a world information database that unlocks as the story progresses.

Upgrade system: Break through power thresholds, such as progressing from ordinary human physique to Marine captain, vice admiral, admiral, and eventually Pirate King level, to unlock new System features, such as party buffs and territory-building modules.

Starting identity: Prince of the Dawn Kingdom in the East Blue. The kingdom is weak and plagued by pirates from the East Blue; the king, Yi Feng’s father, is incompetent, the nobility is corrupt, and the people are impoverished.

Worldbuilding: Strictly follows the One Piece timeline, with the story beginning three years before Luffy sets sail. The protagonist gradually encounters characters from the original work, including the Straw Hat crew, Marine high command, and the Four Emperors’ forces; takes part in key events such as Alabasta, Enies Lobby, and the Summit War; and also explores original plotlines, including the rise of the Dawn Kingdom, original secret realms, and new factions.
