When the Cloud-Parting Demon Emperor devised the plan to encircle and kill Song Qingming, these two Demon Emperors had also been aware of it.
Their task had been to coordinate the assault on northern Wei State, draw out the main force of Crimson Cloud Mountain's cultivator army, and give the Demon Race an opportunity to wipe out the enemy's living strength.
Yet only a few days after receiving word that the baiting plan had succeeded, they received news that the Demon Race's entire army had been wiped out. It was truly hard for them to believe.
One had to know that Ancestor Boyun had not only personally taken action this time, but had also specially invited the Demon Emperor Tiebi from Taiyue Lake in the south to help guard against any unforeseen developments.
With two Late Nascent Soul Great Cultivators joining forces, how could the Demon Race army possibly have been completely annihilated? The outcome was simply inconceivable.
Faced with this utterly shocking news, the White Dragon Demon Emperor and Demon Emperor Mu Yun still could not quite believe it. They hurriedly dispatched capable Demon Kings under their command eastward to investigate.
But those they sent out quickly brought back news that left them even more despairing.
After successfully wiping out the eastern-route demonic beasts, Crimson Cloud Mountain's human race cultivator army had already pressed westward toward White Dragon Valley.
Seeing that they would soon be caught in a pincer attack by two human race cultivator armies, the White Dragon Demon Emperor and Demon Emperor Mu Yun could only abandon their assault on White Dragon Valley and hastily lead their armies northward in retreat toward Golden Feather Mountain.
The moment the Demon Race army made a move, it quickly alerted Li Mufeng and the others stationed in White Dragon Valley.
