From a historical perspective, the Sunset Vein and the Twelve Demon Gods could also be considered old rivals, with the latter almost being another continuation of the Abyss Ancestor's life.
However, the Twelve Demon Gods each had their independent consciousness, and some entities did not want to bear such inherent cause and effect, like the Auspicious Demon God and the Chaos Demon God.
"You're right... I had fought with many strongmen from the Sunset Sect, like Lord Yuan Yang, Lord of the Great Sun Realm, and Great Sins Evils, who are eternal heavenly proud children unparalleled in the ancient times..."
At this point, the Auspicious Demon God looked at Zhou Dao, "But these people didn't have your luck, nor did they have your presence... You intend to reclaim all the power of the Twelve Demon Gods."
"The senior must have known for a long time." Zhou Dao spread his hands, and there was indeed no need to hide such matters.
