The two paused for a moment before clashing once more, sword light and great halberd meeting, severing time and influencing eternity.
In every fragment of space-time, their figures would appear.
Their battle transcended the constraints of time and space.
It felt like an instant, yet also like billions of years had passed.
After another collision, they separated, returning to the primordial chaos, suspended high in the sky, separated by billions of miles.
Mu Changqing's expression was serene, showing little emotion.
The Demon Ancestor's strength was within his expectations.
Furthermore, both were in a probing phase, not yet having used their true trump cards.
The Demon Ancestor's eyes, swirling with demonic energy, paused for a moment, his colossal body trembling.
In an instant, blood energy erupted and churned around him, shattering the invisible restraints. It was as if his power, suppressed by chains of chaos, had been unleashed.
"Very well, Burial Emperor, throughout history, you are the first opponent I have truly acknowledged. Out of respect for your strength, I shall get serious."
As he spoke, billions upon billions of strands of the purest, most essential demonic energy swept in from the boundless depths of the primordial realm behind the Demon Ancestor, forming a supreme rule demonic pool that obscured the heavens and the earth.
From that demonic pool, a liquid as black as ink writhed and flowed along its edges, descending.
It formed strands of demonic flames, falling upon the Demon Ancestor's colossal body.
The demonic energy evaporated, emitting a sizzling sound.
The next moment, an ineffable armor materialized.
The armor was pitch-black, gleaming with a cold, eerie luminescence, brilliant and ferocious.
Its upturned demonic spikes could easily pierce through all the myriad realms.
Terrifying ferocity, unmatched power, even ordinary innate beings would not dare to face the Demon Ancestor's true form at this moment.
At present, the Demon Ancestor held a pitch-black great halberd and wore the armor of chaos.
His ferocity surpassed all ages, his killing intent shook heaven and earth.
Behind him, a scroll of the river of time unfolded, depicting the enemies he had slain throughout his endless years.
There were acquired beings, primordial beings, innate beings, and even the gods and demons born from the subsequent chaos, all of whom had been brutally suppressed and slain by him.
That supreme might, which suppressed all, now truly matched his identity as the foremost demon god of the primordial realm.
The Demon Ancestor looked up at Mu Changqing, billions of miles away, swung his pitch-black great halberd, his demonic might encompassing the world.
"Burial Emperor, unleash your contingency. Do not disappoint me."
Seeing this, Mu Changqing's expression remained calm and cold. He slightly unfurled his right hand, which hung by his side.
With a gentle flick, all things fell silent, and an ineffable aura emanated from Mu Changqing's body, vast and boundless, filled with endless inauspiciousness and strangeness.
Purple light erupted instantly, piercing through space-time, painting the tapestry of eras.
Within his eyes, a shadowy purple bead pulsed.
Moments later, all innate beings in this place felt a suppressive force sweep over them, vast and unspeakable.
Blazing purple light illuminated the divine light of order, transforming into a divine sword of order, which, as it rotated, slashed through eternity and landed in Mu Changqing's right hand.
"You wish to know my combat limit? I shall grant your wish."
Many innate beings trembled, feeling the aura that could annihilate them, wishing they could flee this place immediately.
However, as innate beings, they forcefully suppressed their urge to flee.
With the Human Ancestor and the Demon Ancestor present, they were confident that Mu Changqing could not act recklessly and kill them.
The Human Ancestor's golden eyes narrowed, a look of solemnity flashing across his face as he murmured.
"Back then, when you fought the Heavenly Dao, you used this forbidden power. What exactly is it?"
The Demon Ancestor also felt it. After countless years, he finally knew what fear was.
However, as the foremost god and demon of the innate beings, he would not retreat; he would only become more invigorated.
Even if he were to perish, he would fade away amidst the battle.
Mu Changqing slowly raised his head, the divine sword of order in his hand spewing brilliant light that annihilated all, reflecting countless forbidden anomalies and blood-soaked tapestries.
Then, the two attacked simultaneously.
The moment the sword light and halberd collided.
Chaos shattered, time fractured, all things changed.
The supreme runes intertwined, forming the most extreme killing intent, clashing wildly.
Endless killing intent formed a standoff, terrifying power disrupted the laws of the universe, evolving countless star fields and universes, illusions appearing and vanishing, and then an eternity passed in an instant.
The entire chaos seemed on the verge of being torn apart by their terrifying killer moves. From an immeasurable distance, terrifying cracks spread throughout the primordial chaos.
The Demon Ancestor's eyes widened in rage, his face contorted.
The demonic armor around his body shattered inch by inch, revealing his true form.
Terrifying purple patterns covered his body, as if about to tear him to shreds.
In contrast, although Mu Changqing's black robe was tattered and his black hair flew wildly,
countless supreme purple runes flashed madly on his body, brilliant and chilling, ensuring that his body could withstand this peerless and terrifying collision.
"Damn it, the Burial Emperor is too strong. The Demon Ancestor is no match."
Some innate beings were terrified, experiencing disbelief for the first time.
The Demon Ancestor, who had suppressed innate beings for countless years and was once one of the three ancestors standing side-by-side, was now being suppressed by an acquired being.
Suddenly, an unforeseen event occurred.
The myriad realms, all of history, the river of time, all known places, regardless of time and space, turned into a dead silence.
Immediately afterward, from a distant location in the chaotic space, which was about to be torn apart by their terrifying power.
A slight collision sound could be heard.
The next moment, an inverted black tentacle shattered the chaotic space, bringing with it boundless heavenly might.
Everyone was shocked by this sudden anomaly and turned to look in terror.
The black tentacle was larger than an entire celestial realm by several times. Wisps of black energy coiled around it, giving a feeling of unease and dread.
It seemed to be a tentacle from the most ancient era, shattering chaos, intending to return to this world.
Upon closer inspection, one could vaguely see many terrifying figures standing between heaven and earth, exuding infinite and boundless pressure, like gods and demons of a celestial realm, beings surpassing the Great Dao.
What's more, some had transcended the acquired beings and reached the level of innate beings.
They wielded chaotic artifacts forged from incomparable supreme truth, their eyes emitting terrifying beams of light, coldly gazing at this world.
"Stop, Burial Emperor, Demon Ancestor. The collision of your two powers is too terrifying. It has alerted the Primordial Era. Even across immeasurable time and space, they will follow the trajectory and return. Stop!"
The Human Ancestor's expression changed drastically, and he hurriedly shouted.
Mu Changqing's purple eyes flickered, and after exchanging a glance with the Demon Ancestor, they both withdrew their terrifying powers.
The Demon Ancestor was sent flying billions of miles, with terrifying wounds covering his body, and purple flames burning him fiercely.
However, the Demon Ancestor showed little reaction, his expression remaining indifferent.
His body trembled violently, and the wounds healed instantly.
Mu Changqing was unharmed. His black robe reappeared automatically, concealing his sturdy and majestic form. He raised his hand to retract the divine sword of order, his gaze slightly solemn as he looked at the receding black tentacle.
"The Primordial Era? An era that was expelled and banished."
The black tentacle that shattered chaos was merely the tip of the iceberg of the Primordial Era.
Its size was far greater than that of a celestial realm.
One could only imagine how vast the entire Primordial Era was.
Perhaps, compared to it, all the myriad realms would seem exceptionally small.
