The beings within the Mysterious Demon Realm were far more terrifying than the ferocious beasts, one of the main forces in the first Tribulation after the creation of the world.
The ferocious beasts were vastly, vastly weaker than those beings within the Mysterious Demon Realm.
The weakest beings in the Mysterious Demon Realm were at the Hunyuan Golden Immortal level.
Even when Hongjun had accidentally entered a Mysterious Demon Realm in the past, it had only been the weakest kind.
Yet it had still caused no small amount of trouble for Hongjun, who was covered from head to toe in Lingbao.
Once the things within the Mysterious Demon Realm entered the Primordial Wilderness, they would absolutely plunge it into chaos and might even destroy it.
If things went out of control and the beings from one Mysterious Demon Realm escaped, releasing the beings in other Mysterious Demon Realms as well—
Would that not become a calamity for the Primordial Wilderness?
Moreover, the Mysterious Demon Realm contained Demon God's Grudge.
Once Demon God's Grudge was released, the living beings of the Primordial Wilderness might become infected again and transform into ferocious beasts.
And the place where Xuanqing was currently battling the Great Evolution Annihilation Formation was precisely the location of a Mysterious Demon Realm.
"Spatial fluctuations?
Shizhi, be careful. The space around your location is fluctuating violently. Something abnormal may happen."
Old Ancestor Yang Mei immediately sensed the abnormality in the space around Xuanqing.
The moment his warning left his mouth, the space around Xuanqing abruptly collapsed.
Then, Xuanqing was instantly sucked into the collapsed space and vanished.
However, the Primordial Wilderness possessed an extremely powerful restorative force. The instant Xuanqing was swallowed, the space was repaired.
Yet when the space collapsed, an incomparably terrifying aura leaked out from within it.
