Outer Celestial Demon?
Upon hearing those four words.
Lu Yuan's expression instantly turned grave.
Compared to those Outer Realm Creatures, he deemed the true danger to be the so-called Outer Celestial Demon.
That's an existence even the ancient sages couldn't eliminate, known as the great enemy.
The death of Immortal Guang Chengzi is likely closely related to it.
Recalling the various pieces of information obtained earlier.
So Lu Yuan was very clear.
If such a being were to appear, the threat would be to the entire universe.
Immediately, without hesitation, he spoke, "Go ahead."
"Outer Celestial Demons do not belong to this realm. Back then, a portion of my Jiang Clan and Ji Clan migrated out, traversed the universe to battle, which you should know, but this history is too ancient to easily explore."
"Ultimately, even the descendants don't know why they left their homeland, they only know of the battles."
