The Kingdom of Castile had established a mighty maritime armed force with over 100 Battleships of Third Grade and Above, tens of thousands of soldiers, and a total of more than a thousand ships.
This fleet roamed the Old Continent's coast, the First Circulation Zone, and the Sapphire Sea of the Bantaan Archipelago, and had long been acknowledged as the "Invincible Fleet"!
This fleet made full use of its infantry's strengths, typically employing conventional Boarding Tactics. They would ram enemy ships and, after forcefully boarding, engage in brutal close combat before seizing the vessels of other nations.
To call it the Invincible Fleet was an understatement; it was more like the world's foremost Marines of the day, unbeaten in both naval and land battles.
It sounded as extravagant as their "Supreme Art," but their solid battle accomplishments couldn't be falsified.
After proving their worthiness of the name, this "Invincible Fleet" also earned its own title effect.
