After entering deep into the cave, they walked for three days and three nights. The passage in the cave was becoming broader and broader. Soon, they were walking on an endless rocky plain!
The ground was as hard as iron. Above their heads, they could only see endless melted rocks. They couldn't see the end of this place; it was as if they were walking in a sea of rocks.
Frigid cold wind was blowing with numerous invisible icy blades that were stabbing their bodies. It was an illusionary sting, but it felt real and couldn't even be resisted by magic arts!
However, for powerful cultivators like Xu Que and Jiang Hongyan, this sting would never cause any damage to them except for some discomfort. But it was quite creepy that their True Core Strength was being eroded slowly after being blown by this cold wind.
