Zong Shou also found it extremely awkward. He knew that the sweat from his body was due to his bloodline evolving. The Sky Burning Flame and the other bloodlines forced out the remaining impurities within his body.
Only because his body was close to becoming an untaintable Celestial Body, it was now pale black.
It could be considered a good thing. The sweat wasn't evaporated by the flame right away which showed that the Sky Burning Bloodline had calmed down.
At this moment, although the heart drilling pain was still there in his body, it was much weaker compared to before he became unconscious.
However, as for what the exact situation was, he needed to meditate and look into his body to be able to find out.
Zong Shou was only trying his best to not think about that thing below, to try to calm himself down.
In the past, with just a thought, he would be able to calm down his internal energy.
