When the land was occupied by demons, people had no choice but to flee to the sky. After transmigration, Ricky found that he had become the City Lord of a Sky City. He quickly became familiar with this new world and established a clear direction for survival, which was to resolutely engage in farming (kingdombuilding)! He would farm (kingdombuilding) diligently, develop vigorously, and then gallop through the skies. If anyone disagrees, then launch a great sky battle. Or a war!
In the end, Rocky still decided to withdraw five warships and five Void Magic Warriors from the main force, and together they returned thirty cargo ships laden with medicine to Sky City.
However, this also meant they had even fewer troops at hand. The fleet losing five warships might not have a significant impact, since those withdrawn by Rocky were escort ships with minor damages. Yet the loss of five Void Magic Warriors was a considerable blow to them, as after two batches of withdrawals, only three Void Magic Squads remained—reducing their number by an entire squad.
Meanwhile, let's not forget that they still had to continue attacking caravans. If they intercepted more cargo ships later on, were they supposed to keep sending soldiers to escort the cargo back to Sky City?
