With a trace of decadence in his voice, the words fell, and the order of the dark heaven and earth was restored with divine light, all rules returning to their original state.
A disheveled figure reappeared, standing between heaven and earth in darkness, facing Mu Changqing from afar.
His aura was slightly weakened at this moment, his face pale.
"The most ancient and primal demonic source, this is what I most desire. Although it is external power, if I can have an ultimate battle with you, I will have no regrets."
As he spoke, a rift appeared in the dark heaven and earth, and endless black liquid poured into this world, merging into the Demon Ancestor's body.
In an instant, the Demon Ancestor's aura was restored to its peak, accompanied by ancient and terrifying omens.
The Demon Ancestor's aura transformed and ascended once more, and extremely dark radiance bloomed around him.
This was the most primal Ancestral Source Demonic Light, spanning heaven and earth.
Demonic flames were summoned from an unknown place, slowly rising and enveloping the dark heaven and earth.
His aura surged upwards, shattering shackles and resonating through ancient and modern times.
In a moment, it reached the ultimate realm of the heavenly path, on the verge of taking a new step, a supreme sublimation.
At this moment, the Demon Ancestor was supremely majestic, his demonic might shaking the world, black hair dancing wildly, truly the progenitor of all demons.
The black demonic armor, shattered by Mu Changqing, reappeared, even more ferocious and terrifying, like the origin of creation, the most ancient Ancestral Demonic Armor.
"Burial Emperor, I admit that with my own strength, I don't even qualify to fight you to the fullest. However, if I can fulfill this life, I can't care about that anymore."
As he spoke, the Demon Ancestor's massive, terrifying arm grasped empty air from a distance.
The next moment, endless extreme demonic source from the dark heaven and earth surged forth, evolving into a pitch-black ancestral blade. Its terrifying edge, interwoven with demonic light, emitted a glorious prayer sound, rumbling mightily.
Heaven and earth trembled, and all realms trembled in fear.
This was even more terrifying than the colossal being formed by the fusion of the five great sacrificial seas' inhabitants before.
It was not just due to the degree of transformation, but more so because of the Demon Ancestor's unwavering heart, daring to face Mu Changqing.
"Good, you are qualified to fight me."
Mu Changqing greatly admired the Demon Ancestor, which was why he would erase him in the most brilliant way possible.
As he spoke, Mu Changqing slowly lowered his clasped hands behind his back, extended his right hand, and a long sword enveloped in purple light appeared. Runes covered its surface, resonating with the countless meridian lines of his body, forming a unified whole.
Their gazes met, as if the aura of creation itself appeared in all realms, replaying the grand epoch of the universe.
The next moment, purple light clashed with black light, and a battle transcending the concept of space-time erupted, with various orders and rules intertwining and struggling.
A fierce confrontation fully erupted, Mu Changqing's purple longsword and the ancestral blade clashing madly.
The resounding clang echoed through the dark universe, severing infinite space-time, cutting off the river of time and eternal reincarnation.
Clang!
With another ultimate collision, the ancestral blade instantly shattered, turning into billions of divine gold that fell into an unknown space.
The next moment, the shattered ancestral blade erupted with dazzling divine radiance again, breaking through the shackles of space-time to return to the present, reforming the ancestral blade.
"Kill!"
At this moment, the Demon Ancestor's eyes were covered by endless demonic light, his overwhelming battle intent having long since broken free from the constraints of space-time.
The ancestral blade, transcending spatial limitations, severed eternal time and once again attacked.
Mu Changqing's expression was aloof and indifferent, not surprised by the Demon Ancestor's terrifying aura.
He drew his sword and attacked again, the entire dark heaven and earth continuously shattering and then restoring its order.
This place was the Gray Ancient Road, possessing the most terrifying and primal power of the Gray Ancestral Source, capable of endless revival, achieving true eternal reincarnation, immortal and indestructible.
Therefore, this world would not collapse due to the two exceeding its capacity; instead, it would endlessly recover and be restored.
Of course, if Mu Changqing unleashed his full power, he could naturally break the rules and order of this world, shattering the eternal heaven and earth into nothingness.
After countless rounds of confrontation, the two separated for a moment.
Terrifying fissures, erupting with extreme immortal light, appeared on the Demon Ancestor's body, densely packed and extremely frightening.
The Demon Ancestor looked down at his massive body in a daze, his face filled with a look of despair and disbelief.
"Even with the primal demonic source of the Gray Ancestral Source, I am no match for you. Heh heh, a variable, truly the greatest variable in all realms, reaching an uncontrollable level. Heaven cannot bury you, earth cannot cover you, and even the Gray Ancestral Source may not be able to eliminate you."
After a long while, the Demon Ancestor sighed softly and murmured, as if talking to himself, or perhaps to Mu Changqing.
Mu Changqing's gaze remained fixed on the Demon Ancestor, and he calmly replied.
"You are quite good. More so than the Primordial Heavenly Dao, I appreciate you more. Therefore, I will let you perish painlessly, dying in ultimate brilliance."
His domineering tone suggested he had never considered the Demon Ancestor a rival, but rather a respectable successor.
Hearing this, the Demon Ancestor showed a smile of defeat, as if an old man with a depleted lifespan had suddenly aged billions of years.
He slowly raised his head, his resolute face covered in dense cracks, his origin demonic source swirling around him like chaotic immortal light, gradually obscuring his expression.
"This era belongs to you, Burial Emperor. We... have been eliminated, we are old."
The Demon Ancestor's words were not about his lifespan nearing its end.
As beings at this level, they had long surpassed all sentient beings and controlled eternal time; how could their lifespan be depleted?
What aged was his heart that yearned for the peak.
After a long silence, the Demon Ancestor's aura grew increasingly strange, fluctuating between reaching its peak and threatening to break through the heavenly realm, and then plummeting to its lowest point, becoming an ordinary person.
His thick black hair danced wildly in the wind, and in the dark heaven and earth, it turned white strand by strand.
Mu Changqing stood opposite him, narrowing his purple eyes, and snorted coldly. Endless Dao sounds shattered space and entered the Demon Ancestor's ears.
"Demon Ancestor, do not disappoint me, do not make a mistake."
As he spoke, Mu Changqing's aura grew colder, meridian lines reflecting in the dark heaven and earth, infinite runes flashing with extreme, brilliant light, illuminating their massive bodies.
The Demon Ancestor chuckled, his black hair turning white, and on his face, the look of despair gradually being replaced.
It was an indescribable, inexplicable aura.
It seemed to be the true Demon Ancestor, controlling the origin of all demonic sources, yet different from before. A more primal, transcendent consciousness sought to possess his body and descend here.
"Heh heh... Hehehehehe, I have no choice. Burial Emperor, you are too strong, too strong without limit. With my current body, I indeed cannot pose a threat to you. But even if my consciousness cannot witness your ultimate battle, using my body to participate in this battle is my price."
The Demon Ancestor's low, bitter smile turned into a roar of laughter towards the sky.
His terrifying laughter caused the order of the entire dark heaven and earth to descend into chaos.
Universes, born from the order-breaking demonic sounds, bloomed like flowers, scattered throughout the dark heaven and earth.
Black universes, crystal clear points of light, danced in the sky, endless, descending into the present world.
