Red rain dripped down. Though it could pierce through even a cultivator's immortal artifact, for some reason, when this blood rain fell to the ground, it only corroded part of the surface and did not completely punch through the earth or blast out underground springs.
Many cultivators quickly reacted, and one after another, they flew underground.
"Fly underground!"
"Get inside first! Dodge that rain!"
This place was filled with crisscrossing ravines. The cultivators did not hesitate, flying straight down into them, and within the ravines there were cave after cave.
Even if there were no caves, with their strength, they could easily bore through the mountain walls inside the ravines and hide within.
Song Zhong only glanced at those cultivators, then rose and flew forward. If his guess was correct, there should be danger inside those caves as well. Those cultivators would probably die all the same after going in.
As for directly killing these cultivators?
Song Zhong thought about it, but still did not act. This was only the very beginning of the great calamity. Their Universe was surely not the Universe with the fewest surviving cultivators, so there was no need to kill these cultivators.
Of course, if he saw a top-tier immortal artifact, such as an Earth Rank, Top Grade Immortal Artifact especially suited to him, or a Heavenly Grade Immortal Artifact, he would still make a move.
But thinking about it, no cultivator would bring a Heavenly Grade Immortal Artifact into this place.
"Let's go. We'll find more cultivators from our Universe."
Song Zhong sped forward at great speed, but slowly, he discovered that almost everything he could see was cultivators' corpses, while outside, he could hardly see a single living cultivator.
Clearly, those cultivators had probably all hidden underground to avoid the blood rain.
