If it was just a Qi Cultivation Stage cultivator considering switching to the Demon Clan, it wouldn't be a big deal.
However, reaching the Nascent Soul Realm, the foundation has long been established, making it impossible to change the foundation.
If forcibly absorbed, it would only disrupt the body's foundation, leading one to perish along with their cultivation path.
"Right, the aura of the ancient demon doesn't affect me that much."
"But what about my Gu Insects?"
"Perhaps my Gu Insects could devour this strand of ancient demon aura."
At this moment, Zhou Sui's mind stirred, thinking of the thirteen Gu Insects in his body.
After all, the Gu Insects present in him were not human, but another species, non-demon, non-human, non-demon.
It remained uncertain if they could devour the ancient demon aura or not.
With that thought, he decided to give it a try because there would be no harm in doing so.
If successful, the benefits would be sizable.
