Since antiquity, after the rise of Atlantis which later culminated into the overlord Atlantis Empire, Mega Fleets with dozens of Annihilators were widely known as the trump cards of this leading variant human race.
The Generals and other warlords that were produced by this overlord race were usually the ones who took the helm of these massive war fleets.
Generals who cultivated so hard until they got to the esteemed Gold Realm were the pinnacle warlords that took the helm over Mega Fleets.
This combination of powerful warlords and Mega Fleets was a mighty one, but it was not the main pivotal trump card that the Atlantian Empire had.
The Atlantian Empire could mass-produce warships to arm a Mega Fleet with thousands of them, they could even speed up the production of Annihilators, but wars of this scale could not be won with just quantity.
