The Earth Fire Room was brightly lit, the entire stone chamber filled with a red aura.
The red aura also fell upon Ye Xuefu's face, which, beneath its rugged and plain surface, seemed to hold a turbulent wave of emotions.
Ye Jingcheng watched for a while and tried closing his eyes as well.
In the past three months, Ye Jingcheng had depicted the Pill Formula more than once.
But each time it was slightly off, with Ye Xuefu providing the final answer.
However, this time, because it was a Foundation Establishment Pill, Ye Xuefu couldn't give him the answer.
He had to think with twelve parts of his mind.
At this moment, he also tried to immerse himself like Ye Xuefu.
He closed his eyes and meditated, but his six senses were not shut down. Under the high temperature, he felt the Earth Fire.
With the unveiling of the Jade Box, he sensed the aura of Spirit Medicine.
At this moment, it was as if countless pharmacological principles were combining and matching in his heart.
