You Already Dominate the Galaxy, but You Still Use Civilian Transport Ships?

5V5 starship battle At the beginning, you inherit a dilapidated civilian interstellar transport ship and activate the black technology system... A certain top interstellar assault ship: There is no fleet in the entire galaxy that we cannot assault! Except for that damn transport ship. A certain ace star destroyer: After taking a nuclear bomb from that transport ship and not completely dying, he is an ace. A certain heavy interstellar frigate: Just one encounter, and our ion shield has a hundred more holes! A certain beyond-visual-range interstellar cruiser: It was attacked by someone half a light-year away. Can anyone tell me who did it? A certain imperial starship: My 100,000-meter-wide deck is about the same size as the toilet on that transport ship. A certain interstellar fortress: In the year 12345 of the Galactic Calendar, we, with one million interstellar battleships and ten imperial fleets, were attacked by a... Civilian transport ship.
