This aura.
Qin Heng was not unfamiliar with it. In fact, it was a very familiar aura—the aura of the Nine Nether Evil Demons!
In the Immortal Cultivation World, it is commonly referred to as Demonic Qi!
Originating from the terrifying and gloomy Nine Nether Demon Realm, it is the unique aura of the Nine Nether Evil Demons, posing great danger to all beings not from the Nine Nether! Mere contact could directly turn one into a Nine Nether Evil Demon! Moreover, they would transform into low-level demons devoid of all reason and wisdom, monsters that only knew slaughter and bloodshed!
However, the Demonic Qi in this hotel was not dense; it was very faint. If Qin Heng hadn't shifted his attention to it, he might not have even noticed it at all. It was, one might say, extremely diluted.
This level of Demonic Qi is essentially equivalent to some potent toxins; not very dangerous.
But, since such a thing had appeared, Qin Heng could not ignore it.
