The Ghost Ridge Valley Sect wasn't merely one of those unorthodox sects labeled as such for practicing slightly "negative" techniques. Their practices were utterly vile, involving the harvesting of souls from humans and creatures alike, as well as enslaving them for their purposes.
Lin Mu could understand the Shanxi Empire supporting or interacting with the Seven Mystics Immortal Sect and even the Twin Mountain Polarity Sect, but the Ghost Ridge Valley Sect was a line that should never have been crossed.
"So, they openly support them too?" Lin Mu raised his brows in disbelief.
"A Ghost Cultivation sect," Xukong remarked. "Someone like them would certainly possess the expertise to manipulate the Soul Ensnaring Great Formation Array."
"It's highly probable that they were the original owners of the inheritance ground as well," Lin Mu reasoned.
He searched for more clues but found nothing concrete to confirm his suspicion.
