The Devil Race army surged in like a flood, occupying the entire Myriad Devil Diagram of Stealing Heaven, holding this vital passage, and maintaining its offensive against the Dragon Palace.
Even if Lu Xiaotian managed to guard the hidden passage to the Dragon Palace, the small-scale passage would not be able to take away many dragons—at most a scattered few thousand or over ten thousand. That would already be the best possible outcome.
Before long, the elite Devil Race army that had entered the Myriad Devil Diagram of Stealing Heaven numbered several million. Among them were several Devil Lord guards, such as the Gold Toad Devil Armored Soldiers and the Sunflower Yang Flame Arrow Guards. These Devil Lord guards were also the main force attacking the Dragon Palace.
Just as the vast Devil Race army continued advancing, the thunder sea deep in the void seemed to have been drawn by something. Like countless warhorses galloping forth, it carried an aura capable of destroying everything as it came hurtling madly toward the Six Extremes Dragon Palace.
"Damn it!" The Ancient Desolation Devil Emperor's face instantly turned ashen. The moment the boundless thunder erupted, he had already sensed something was wrong, but by the time he reacted, it was too late. He had no power to stop it and could only watch helplessly as disaster descended.
The Devil Race's main army was far too concentrated at this moment, and a considerable portion of its elite forces had entered the Myriad Devil Diagram of Stealing Heaven. Lu Xiaotian's move was equivalent to striking them while they were halfway across the river. In an instant, the Devil Race army went from holding every advantage to being trapped in a dilemma with no way forward or back.
"Attack! Attack the Dragon Palace at all costs!"
