To be precise, the entire challenge domain was trembling!
Even Zong Shen, riding on Eagle Sauce's back, could clearly sense the instability within the domain.
"Holy shit, it can do that?!"
Zong Shen was somewhat astonished as well. Clearly, the Archdemon Artorius had pulled off an extraordinary move!
It had first used the summoning secret art of the Demon Codex to create that altar.
Then, it used its own Archdemon Blood as a medium or catalyst to activate the altar, initiating a mysterious ritual known as Oblivion that caused the altar to frantically draw in souls of the dead.
Finally, it used the power of those souls to unleash that black pillar of light that connected heaven and earth.
It was precisely that seemingly awe-inspiring black pillar of light that had destabilized the entire Defense Challenge domain.
One had to know that this domain was a temporary domain constructed by the Lord System specifically for the Defense Challenge.
Although it did not possess complete underlying rules or the potential for evolution like the Endless Continent, its stability far surpassed that of ordinary demi-planes. Yet such a sturdy domain had actually begun to stir under the penetration of the black light pillar.
The sky curtain began to change, while the space above, below, left, and right all trembled faintly.
Zong Shen focused his senses for a moment and discovered that he could no longer use [Falling Walk]. This indicated that the space within the domain had become extremely unstable.
The sky curtain overhead was also undergoing changes that were difficult to predict. Originally, it had constantly emitted a gentle radiance.
But at this moment, the spot where the sky curtain touched the black pillar of light gradually turned black, as though a translucent backdrop had been dyed into a black curtain.
