In the grand hall.
Lin Yuan sat at the main seat, his gaze overlooking, a figure as if godlike.
Nine Heaven Grade Demon Formations vibrated unceasingly.
As if they encountered their master, they gradually calmed after a long time.
Xiahou Yuan was exceptionally unique; to the countless demons, as long as they cultivated demonic arts, they would kneel upon seeing him.
This was a suppression stemming from the essence of life.
Even if someone was stronger than Xiahou Yuan, they would be affected, though the intensity might be less, they wouldn't necessarily kneel at first sight.
Of course, only Xiahou Yuan himself knew this.
As for those demon lords who had followed Xiahou Yuan, they were not aware of this mystery; they only knew that in front of Xiahou Yuan, they could not muster any thought of rebellion.
Demon Lord Moyang and the other nine great demon lords believed that by relying on the nine Heaven Grade Demon Formations, they could make Xiahou Yuan retreat with difficulty, or at least block him.
But unfortunately.
Though the nine formations were strong, they required demons to control them.
As long as demons were involved, Xiahou Yuan stood invincible.
This was the same reason Lin Yuan dared to enter the underground palace alone.
