As someone in the midpoint of the Physique Transformation realm, having to listen to the crap this guy kept spewing was an insult to his martial prowess. The frustration made Shen Kai take a quick decision.
If Han Xuhan had any trump cards, he would have played them before degrading himself like this. What a righteous cultivator valued the most was his honor.
Besides, what can a cultivator with such a weak aura even do to him? This Crimson Snow Sect disciple barely seems to have scratched the surface of Mystic Arts, let alone set foot in the other, less travelled paths.
On the other hand, Mu Ran was waiting inside the tunnel. That guy was a real opponent, someone he couldn't see through.
Shen Kai's instinct told him that taking care of Mu Ran would be difficult. He had to finish up the work on this side as fast as possible lest Mu Ran should suspect something.
