They were now in an extremely huge karst cave. It was obvious that it was formed purely naturally. The surrounding rocks had been corroded by the devil qi and were deeply sunken.
Only the spot where the two of them were standing was still intact, forming a platform with a radius of several hundred meters.
Huang Yueli stood up and walked to the side for a while before she came to the edge of the high platform and stretched her head to look down.
Because of the erosion of the devil qi over hundreds of millions of years, the depression had already formed a bottomless gully, like a cliff.
Because it was really too deep, Huang Yueli couldn't see the bottom of the ravine and could only see a black mist.
This mist was a mist droplet formed from extremely dense devil qi.
