Luo Xiao became absentminded as he looked at the sphere of energy that was right in front of him. His eyes zoned out, and his body became limp. He felt confident that the thing which had been calling for him was this ball of light and energy.
Jiang Yao kept observing both the ball of light and Luo Xiao, but while his facial expression was somewhat grave, his heart was beating rapidly in excitement.
This sphere of energy was not unknown to him. While he had never actually encountered one, he knew what it was, and the fact that it had been calling for Luo Xiao was truly the younger man's luck.
The pulsating energy that came from the sphere was not only full of heaven and earth essence, it was also full of life force, and it was clear that the whole cave had been kept alive by the energy that was pulsating from the sphere.
