The surprise attack by the Mysterious Ship was different from the encirclement and suppression battles that had been encountered before. Because of the Mysterious Ship's special characteristics, even if the enemy was prepared to win by numbers, a clever leader wouldn't fail to realize the seriousness of this situation.
It was because these leaders had realized the gravity of the situation that they were recruiting survivors at all costs, having the Martial Artists on board look for opportunities to first eliminate the micro Mysterious Ships.
These micro Mysterious Ships were actually like fleas attached to some kind of top-level creature. Although the analogy might not be entirely accurate, the principle was not wrong.
