"What happened?"
As the highest commander of the Third Fleet's garrison, Costello rushed to the command center the moment he heard the alarm.
"Commander Costello, the early-warning systems deployed outside the base have detected a large number of Unknown Fleet forces heading our way. Their numbers exceed one hundred legions!"
"Gramm United?"
Costello frowned and immediately asked.

"Only three hou—wait, did you say three hours?"
"Yes. Their travel speed is even faster than Gramm United's!"
"Damn it. How many combat-capable fleets do we have
