Although Ling Tian and the others had easily scattered three layers of tribulation clouds, Chang Xiangsi and the others still couldn't relax. No one knew how many layers the Ultimate Lightning Tribulation they had triggered would have. If there were too many, then even if Ling Tian and the others remained in good shape, they might still struggle to pierce through them all. By then, the Entity Arrows in everyone's hands would be nearly spent—or completely exhausted.
It made sense. Although all cultivators could launch energy arrows, those were more easily destroyed by lightning. It would be nearly impossible to affect the tribulation clouds that way, so Entity Arrows were the best choice for attacking them.
But each cultivator had only a limited number of Entity Arrows. Even Ling Tian had just 1,080, which might not be enough.
If even Ling Tian might run short, the other cultivators would fare even worse. They had far fewer Entity Arrows than he did, and most had refined fewer than a hundred. Every cultivator had limited time and energy, and nurturing so many Entity Arrows at once put enormous pressure on them. Few could refine and nurture as many arrows simultaneously as Ling Tian.
Fortunately, everyone knew the number of layers in the Ultimate Lightning Tribulation's clouds was limited. Moreover, Ling Tian would attack first, and a single strike from him could pierce the clouds. That meant the other cultivators would only need ordinary Entity Arrows—or even multiple Impact Arrows—to keep the clouds in a constant state of dispersal. Their arrows should last them a good while.
"Before now, the most any cultivator had ever triggered was seven layers of tribulation clouds. Those cultivators were far weaker than Ling Tian, but they were still the strongest among those undergoing tribulation. That gives us
