Because he could sense clearly, as Heaven and Earth Spiritual Qi continually tempered his body, his muscles and bones were greedily absorbing this Qi, visibly becoming stronger at a rapid pace.
Also, as the Heaven and Earth Spiritual Qi permeated his body, his pores began to exude beads of sweat, which carried black impurities, giving off a strong, unpleasant smell.
Seeing this condition on his body, Shen Luo revealed a hint of surprise in his eyes.
During the Qi Refining Stage, he had experienced the process of Heaven and Earth Spiritual Qi replacing his marrow. He had assumed all the impurities in his body had been eliminated during that time, but it seemed there were still many residues left!
If he were not cultivating the Huangting Technique, he wondered how much longer these impurities would have stayed within his body.
As the black impurities were expelled one after another, his body felt significantly lighter, as if he had shed a heavy burden.
