After two powerful attacks, Ling Tian finally pierced through the eighth layer of tribulation clouds. The hole wasn't very large, but he had broken through it all the same. That would make it easier to pierce through and disperse the surrounding clouds, and would reduce the number of Entity Arrows he needed. Sure enough, Ling Tian's next attack used only three Entity Arrows, saving him quite a few.
Meanwhile, Chi Xue and the others hadn't been idle while Ling Tian attacked the eighth layer. They continued their assault, punching even more holes through the seventh layer. A vast area of clouds above their heads had already dispersed, which meant they could temporarily leave the seventh layer alone and attack the eighth. Of course, their attacks still passed through the area occupied by the seventh layer and the six layers below it, and their powerful strikes dispersed any clouds that had just gathered there.
The clouds above the other cultivators also remained dispersed for the same reason. Clouds that had already dispersed were much easier to disperse again after they gathered anew; even the energy radiated by energy arrows or Entity Arrows was enough to do it.
Keeping the lower layers dispersed while attacking the higher ones was the best way to ensure a successful tribulation. It also used the fewest Entity Arrows. Whether they could disperse all the clouds, pierce through the firmament, and open a passage to the outer realm would depend largely on how many Entity Arrows everyone had left in the end.
The main reason they could keep the lower layers dispersed was that so many cultivators were undergoing the tribulation this time. With over a million cultivators attacking at once, keeping the clouds dispersed was relatively easy. After all, the total amount of clouds they faced
