After hearing Ling Tian's clone analyze the situation, everyone realized that the Lord of the Universe would surely have other ways to test or wear them down. However, they weren't too concerned. In their minds, even the Nine Nether Nether Soldiers, skilled in Phantom Combo Merged Entity Arrows, couldn't do anything to them, so other methods naturally wouldn't pose much of a threat either. In short, they had great confidence in their methods and strength, and believed they could handle any test.
Most importantly, even if things went awry, they could abandon the formation and use their mobility and greater expertise with archery to maneuver against the Nine Nether Nether Soldiers. Although abandoning the formation would mean they couldn't reach the Demon God Forbidden Ground in time when the Lord of the Universe moved against Ling Tian, and thus couldn't attack his true body, they felt that all they had to do was give it their best. Besides, they had already thought of a way to handle such a situation.
That's right, Chi Xue and the others had figured out how to deal with being forced to abandon the formation. For example, they could attack the Lord of the Universe before Ling Tian did. When they'd learned earlier that Ling Tian and the Lord of the Universe had agreed to a five-thousand-year truce, Chi Xue and the others had decided to strike before the agreement expired. This would naturally draw the Lord of the Universe's attention and relieve some of the pressure on Ling Tian. They also believed that, with their strength, they could force the Lord of the Universe to make a major move, which Ling Tian would sense. With his intelligence, he would naturally be able to piece together what was happening and immediately join forces with them.
