As the Burial Sky Blade was forced steadily backward, countless cracks spread across the surface of this incomparably hard Civilization Supreme Treasure-grade weapon.
Along with them came bursts of teeth-grating metallic clanging and warping screeches.
Civilization Supreme Treasure-grade items indeed varied in quality.
The Creation of the Heavens Divine Axe in Pan Gu's hand was undoubtedly among the very finest of all Civilization Supreme Treasure-grade items.
Especially when wielded by Pan Gu himself—he could split even "heaven and earth" apart, let alone anything else!
And the Burial Sky Blade in Darkness Demon Ancestor's hand was naturally also an exceptional existence among Civilization Supreme Treasures.
But compared with Pan Gu's Creation of the Heavens Axe, it was clearly still a step behind.
More importantly, the gap between Darkness Demon Ancestor's current strength and Pan Gu's was simply far too great!
Darkness Demon Ancestor was merely at the Half-Level-9 Peak—perhaps, in Pan Gu's eyes, already a Quasi-Level-9 lifeform—while Pan Gu...
The stifled collision continued!
Although Darkness Demon Ancestor's strength fell far short of Pan Gu's, and even his Burial Sky Blade was nowhere near as formidable as the Creation of the Heavens Divine Axe, Darkness Demon Ancestor refused to concede defeat!
Unlike Nether Bone Demon Ancestor, who had possessed almost no room to resist before being instantly slain by a single blow from Pan Gu, Darkness Demon Ancestor could clearly hold on much longer!
The enormous Creation of the Heavens Divine Axe kept descending from high above the starry sky, driving Darkness Demon Ancestor's Dominator body steadily downward with it.
The Burial Sky Blade continued to emit teeth-grating sounds of metal cracking and clashing, yet Darkness Demon Ancestor remained motionless beneath the Pan Gu Axe, without retreating a single step!
The terrifying collision of power above directly unleashed incomparably violent energy tides
