After several rounds of battle, the Star Power within the five Guardian Beasts was nearly depleted, and it was already noon. The five were also quite hungry, and they had run out of bait.
As a result, Chu Chen decided to leave this place temporarily, to first find a safe location for a short rest.
Secondly, they needed to go out for food, as the surrounding two kilometers were all the territory of the Gray Rock Ants, requiring them to leave the area for sustenance.
Finally, they needed more bait. Chu Chen wanted to prepare more, as there were still many Gray Rock Ants. Missing this opportunity might mean there wouldn't be another.
Two hours later, the five returned near the ant nest.
After numerous battles, the five had become very adept at using this set of tactics, almost to the point where Chu Chen didn't need to direct them, and they each did their part making all the preparations.
