Concealment

Pushing the door open, Hui Yue's heart started beating faster. His body was currently reinforced with the strength of the red gem, but even so, he was not invulnerable. The expert he was up against was someone who consumed souls like he did; it was likely that he also possessed soulforce. If he had developed his soulforce to the point of being able to attack, then Hui Yue's soul could be in danger.

Even if this expert did not have soulforce, he still walked down the dao of devouring much like Hui Yue. He had discovered earlier, it was possible to rip the soul of one's enemy out of their body when one reached mastery in the dao, and Hui Yue did not wish to have to deal with such an attack.
