Upon swallowing the pill, an unending wave of miraculous healing spread throughout his limbs and body.
With the constant diffusion of the healing force, an endless stream flowed within him, akin to pouring molten rock into his being.
Scorching!
Boiling!
The skin all over his body was burnt crimson, every inch of his flesh felt the pain and itching.
At first, it was barely noticeable, but it quickly intensified, as if countless white ants were gnawing at him from the inside.
The sensation permeated his marrow!
Pain! Pain! Pain!
For the first time, Xu Mu became aware of the pains that accompany foundation-building.
"If I, who took the superior foundation-building pill, am experiencing such pain, what about those cultivators who've ingested the inferior ones?"
A flicker of doubt passed across Xu Mu's mind.
What Xu Mu didn't know was that the excruciating pain was specifically because he had consumed a superior foundation-building pill.
