Bai Ning Bing opened her eyes and the first thing she saw was warm yellow light.
"You are awake." A seemingly familiar voice resounded in her ears, but she could not be certain.
A few breaths of time later, Bai Ning Bing's vision became clearer.
She saw Fairy Miao Yin and Black Tigress beside her.
Bai Ning Bing barely had any strength left, she used her hands to push her upper body up: "Where is this?"
She looked around and saw she was in a cave. The cave was extremely peculiar, its form was like a sphere, and Bai Ning Bing's group was at the bottom of the sphere.
The spherical cave's inner walls had large patches of scattered yellow soil. From time to time, red lights flashed, like they were flowing on the yellow soil which seemed to condense into blood veins.
"Wait a moment, these are…" Bai Ning Bing was bewildered. She saw immortal materials embedded in the inner walls at set intervals of distance.
