Gula Star System.
A metal sphere the size of Earth floats in space.
This metal sphere is a powerful antimatter missile launcher.
It's said that this antimatter missile launcher can emit missiles with a destructive power covering up to five light-years.
The most important thing is, it can fire continuously, up to four antimatter missiles.
"Everyone, hurry up!"
"We've received news ahead; that steel beast is rapidly approaching us."
"We must install all the energy stones onto the launcher before the monster attacks."
Tens of millions of cosmic engineers, wearing convenient cosmic flight suits, swiftly installed fist-sized energy stones onto the antimatter missile launcher.
Finally, after working for an entire Earth day, all the energy stones have been installed.
The chief engineer checked the launcher, confirmed there were no issues, and reported back to Commander Acotina and other frontline commanders.
