Currently, there was a stone cliff stretching into the distance in front of Yi Yun. The spot where the Purple Crystal was pointing to was within this stone wall.
"Stone wall…"
Yi Yun frowned slightly. This stone wall did not seem peculiar. Could there be some mechanism to it?
Yi Yun reached out and touched the stone wall. The stone wall was scorching hot. Even with the Purple Crystal protecting his hand, Yi Yun found it unbearable.
He found nothing, yet the Purple Crystal was pointing here.
There had to be something odd with this stone wall. The burning hell's temperature was so high, yet it was unable to burn or melt this stone wall.
Yi Yun pulled out his Thousand Army Saber and slashed out a chunk of rock.
Yi Yun examined the dark red stone in his hand again and again, but he could not discover anything special about it.
Yi Yun circulated the 'Tai Ah Sacred Technique' and injected Yuan Qi into the rock.
"Peng!"
