The battle indeed ended very quickly.
Even faster than anyone had imagined—it was over in less than ten minutes. The frenzied Demon Beasts reluctantly retreated—they were mad, but not about to throw their lives away for no reason. After confirming that the enemies they faced this time were not as easy to deal with as before, the Chaos Monsters promptly obeyed their instincts and rapidly evacuated the battlefield.
And the Demon Beast Lord, after taking a direct hit from Iona's flagship's full broadside, simply ran away... Honestly, the fact that it didn't die on the spot was enough to surprise Fang Zheng. He had to admit, these troublesome creatures did seem quite resilient, although, if Fang Zheng had to say, perhaps their small size was also a factor.
After all, some always slip through the net when you're clearing the ground.
