"The Mercury Zerg are expected to reach Mars in about two hours."
The peak speed of the Zerg is, of course, faster than this, but maintaining a high speed requires more energy. To preserve energy reserves for the war, they generally don't accelerate to a high speed at the beginning.
Human warships are the same; they only accelerate or run thrusters at overload during emergency situations.
"My interception fleet has been dispatched and will intercept the Zerg in space!"
He Xingzhou immediately said, "Make sure to maintain a safe distance! If the Venus Zerg initiate a collision, withdraw immediately!"
"Yes!" Luo An responded.
The Blue Star Alliance immediately held an emergency news briefing. The spokesperson announced, "Latest news, the Venus Zerg and Mercury Zerg have mobilized and are going to attack our Blue Star and Mars. Both planets are entering a state of war immediately. Combat units are to be dispatched immediately, and other personnel should prepare for refuge!"
