Like a massive boulder crashing into a mirror-like sea.
Amid Blood Sea Demon Roc's wails, the Vast Radiance Divine Sword cleaved open a line of blood, sent three giant demons flying, scattered the gray-black shockwaves, and drove straight into the depths of the Demon Kingdom's core.
Its momentum did not diminish. Dazzling radiant light pointed directly at the eighty-one demon mountains, and even the Great Abyss of Avici at the very heart of it all—the place where the Holy Demon resided.
Heavenly Monarch Xi Yi was not acting rashly. He had vaguely sensed that the standoff between the human race of the Tianyuan Realm and the Demon Kingdom was not as it appeared on the surface. The Demon Kingdom did not truly hold an absolute advantage in strength and numbers, and the Demon Kingdom itself was likely not so united from top to bottom.

In any case, He was not the oldest one. If they struck Him, Junior Brother Chenyin would back Him up, Ancestor Chengguang would cover for Him, and Ancestor Haotian would bear the burden!
With an angry roar, divine power surged. The sword light that devoured demonic qi became wild and explosive, like white lightning tearing apart the sky. The nearly endless, dense demonic qi along its path, enough to block all sight and detection arts, was torn open in an instant. If no more demons intervened to stop it, it truly might break through every defense of the Demon Kingdom and blast into the abyss.
By this point, it was impossible not to act. From the shadows, a massive monster leaped into the air and charged forward to meet it!
BOOM!!!!
It was a giant. It
