Stakes of the duel

Blank.

With just one part of one sentence, this bastard managed to undermine all the calmness that I was trying to build up. My dead father? Did he actually dare to harm the only person from my family that really cared for me?

As that news attacked my mind, I momentarily lost the control of my aura, letting it leak a bit for a moment, before forcefully retaining it. Considering how he was only at mortal enlightenment level, there is no way that he would notice it, but from the look of surprise that the guards gave me, I'm certain that at least they noticed it. 

There is a distinctive element to one's aura, that doesn't show one's cultivation, but is based on density and clarity of one's energy. By climbing the ladder of cultivation levels and realms, one's mana turn denser and denser, with its clarity being the main limiting factor in one's growth.
