No light, no water, this is what it's like a thousand feet deep underground.
Zhouyang followed Ma Shaoyang, flying downward through a hole hidden beneath the Desert Sea, and soon arrived in such a place.
Zhouyang wasn't clear about the size of this underground cave, but the environment was indeed very harsh.
In such an environment, even demon beasts accustomed to the harsh conditions of the Boundless Desert Sea cannot survive here long-term without Tier Three strength.
After all, unlike human cultivators, demon beasts cannot carry Grain Avoidance Pills or large amounts of fresh water, nor can they use spells to condense water vapor into potable water.
For instance, Zhouyang carries dozens of jade bottles of Grain Avoidance Pills with him year-round, and his Water Storage Spiritual Artifact holds a large amount of water.
