Am I the only one who finds this power weird? "Zhou Mu was seriously pissed off, and decided to release his own natal spirit. The natal spirit was a shadow with the eyes of Satan. Evil mental power was permeating around Zhou Mu. Ye Futian recognized this natal spirit. It was a mind controlling natal spirit" I mean, it's a chinese webnovel, first time I see reference to Satan. What's more, a power related to Satan. It sounds weird.
That's call Xuanhuan. Xianxia is for Chinese related, while Xuanhuan is for others than Chinese, typically a mix of Western cultural/mythology/etc....
Likely a mistake in translation. And even if not, i wouldnt say the power itself is centered around satan just because he was mentioned in the text, imagine something like a demonic power instead
