At Sea, I Usher in an Age of Advanced Technology

In the world of pirates, even the strongest fighters settle everything with their fists. It's primitive and inefficient, while every firearm and other modern weapon is nothing more than a decoration.

But when Ronan activates the Black Technology System, he knows it's time for this world to change.

Artificial earthquake generators, aerospace carriers, space-based ion cannons, Dyson spheres, two-dimensional foil, neutron battle stars...

Black technology far beyond its time crushes the competition, completely transforming the nature of warfare in the pirate world.

A few months later.

As the Summit War begins, Whitebeard abandons his pirate ship and surfaces with an underwater aircraft carrier fleet. Giant warships blot out the sky and surround the island, blasting their way into Marine Headquarters with ironclad ships and heavy guns.

"Sengoku, the times have changed," Whitebeard says, standing on the carrier deck with his blade in hand.

The age of great pirates, when ships sailed by wind-powered sails, comes to an abrupt end. An unimaginable era of black technology crashes down upon the world.
