[Navy story] [Young protégé development] [System story]
After transmigrating into the world of One Piece as Sengoku's grandson, he gained Logia and Paramecia Devil Fruits, including the Sword Pill Fruit, through the Killing System. Taking advantage of his natural head start, he spent nearly twenty years building his strength before finally reaching the pinnacle of the world!
On the plaza at Marine Headquarters, Marineford, stood Zhan Feng, the youngest Fleet Admiral in Marine history. He stood proudly atop the raised platform. Below him, the eight Marine Admirals stood in formation, along with the Marines' elite officers, led by Zoro and others, and 100,000 elite Marine soldiers standing in perfect ranks.
Portgas D. Ace, Monkey D. Luffy, Sabo, Borsalino, Sakazuki, Kuzan, and the other Admirals saluted the Fleet Admiral first!
The elite guards and 100,000 Marine soldiers shouted their salute in unison!
“Justice! Justice!”
Zhan Feng saluted all the Marines and read aloud: “Warriors who fight for justice, the days of pirates running rampant will soon be over. The Celestial Dragons and World Government looming over the Marines will become a thing of the past. Let us welcome a new era together! Justice will prevail!”
The writing is pretty good, at least I think it's pretty good.
