The leader of Heavenly Demon was unable to believe that his strength was not enough to make Ye Xiao take even a single step back.
How could he know that Ye Xiao, in his human form, was already powerful enough to kill him with a single thought? Now that he has transformed into a 500-meter-tall Heavenly Demon, his strength also multiplied. As of now, he was no longer an Origin Fusion Sovereign who has just entered this realm, he was already a peak Demonic Sovereign Realm Heavenly Demon.
Talking about The Demon Wheel Realm, it is a unique cultivation base for Heavenly Demons only.
Just like humans and other races, Heavenly Demon could cultivate to Chaos Overlord Saint Realm. However, after that, the path of Heavenly Demons steps on a separate road. Humans and other races cultivate the Nine Vast Origin Sea Realm, Origin Fusion Sovereign Realm, Mystic Sovereign Realm, and Chaos Sovereign Realm.
