Earth Civilization's thirty escape pods were accelerating away.
Behind them chased a colossal Cosmic Battleship measuring one hundred thousand meters.
The Cosmic Battleships of the Double Star Civilization were equipped with the most advanced Annihilation Engines, allowing even such massive vessels to swiftly accelerate to half the speed of light—150,000 kilometers per second.
After all, the Double Star Civilization has been a second-level civilization far longer than Earth Civilization and had more mature applications in various aspects of Annihilation Technology, including the Annihilation Engines.
Thus, the 25th Squadron of the Double Star Civilization was somewhat faster than the escape pods, gradually closing the distance under these circumstances.
When the distance between them reduced from ten astronomical units to nine, eight, seven... to one astronomical unit.
