Upon hearing these words, Zhou Yu and Gu Zifeng both showed expressions of shock.
"What?"
"Dark Demon Emperor?"
"Is there really such a terrifying existence?"
Gu Zifeng was so shocked that his mouth couldn't close.
After all, as a Taoist Sect disciple, he was most knowledgeable about such demons.
The Taoist Sect has been clearing Dark Demon Qi for over a thousand years.
During this time, the most they cleared were Demon Weapons, followed by Demon Generals.
In fact, demons at the level of Demon General were already rare.
Above Demon General in rank is Demon Marshal.
This level of demon is equivalent to the Ancestor Realm Expert among humans.
It is almost impossible to encounter.
In thousands of years, all the Demon Marshal-level demons encountered by the Taoist Sect have added up to less than a hundred.
But Demon Emperor has never been heard of.
This level of existence has surpassed the Ancestor Realm; no one knows just how terrifying its power is.
