"I didn't expect you could sense the aura of people from the Upper Realm?" Lin Fei was surprised by Zhang Fan's ability, but Lin Fei also knew that Zhang Fan was probably referring to the aura of people from the Upper Realm.
"Because the aura of those from the Upper Realm is distinctly different from yours," Zhang Fan replied.
"What's the difference?"
Lin Fei didn't understand, why couldn't he feel the difference? It's all Heaven and Earth Qi; is there a difference?
Zhang Fan explained Lin Fei's confusion, "The aura of people from the Upper Realm is different from those in the Lower Realm. You're using Primordial Energy, right?"
"That's right, it is indeed Primordial Energy. Heaven and Earth Qi flows into our bodies, and this Heaven and Earth Qi is the source of our strength," Lin Fei said.
