"Are you really a disciple of the Saint?"
Jiufeng looked wary and then scrutinized Xuanqing closely: "Judging by your outfit, you indeed seem to be a disciple of the Xuan Sect and you do not carry the aura of the Demon Clan!"
"Guaranteed genuine!"
Xuanqing quickly echoed.
As he spoke, he also revealed a bit of his mana aura. Although the mana cultivated by the disciples under The Three Pure Ones might vary slightly, it fundamentally contains Innate Pure Qi.
As for the Demon Clan, their aura is disordered and impure, especially those below Daluo from the Demon Clan. Because they cultivate the "Heavenly Demon Refining" using the Power of Celestial Stars to refine their physical bodies, they invariably contain some Power of Taiyin, which makes them easily distinguishable from other cultivators, like candles in the darkness of the night.
