Boom—
At the highest point of the firmament, endless Forbidden Heavenly Thunder descended—the most terrifying kind that could make even Supreme Ones pale. At this moment, it all crashed down toward this person.
Because he was attempting to alter the past, reverse space-time, and strike from two different temporal points.
The Primordial Heavenly Emperor's expression changed. He sensed that the other party was not merely speaking idly but was acting in earnest. With a great shout, he declared: "Heavenly Emperor Decay Imprint!"
It was the same Heavenly Emperor Decay Imprint, but when executed by the Primordial Heavenly Emperor's true body, it was many times more powerful than when used by his divine avatar. It carried the infinite might to decay the great cosmos.
"Chaos Heavenly Emperor Imprint!"
The mysterious existence wreathed in Chaos Mist also roared, instantly unleashing a divine imprint of terrifying, peerless power. Space-time seemed on the verge of shattering, as if a Chaos Heavenly Emperor himself was striking out, sweeping through three thousand great worlds to heavily blast the opponent.
Boom—
The two strongest beings from the present and the future collided. Space-time shattered, everything seemed to be heading toward an end. The River of Time itself stilled and fractured, appearing to break its flow.
This was something that had not even occurred during the great battle of numerous Supreme Ones, yet it was happening now—sufficient proof of what level of existence the two combatants were.
The Primordial Heavenly Emperor staggered back, step by step, each footprint stained with blood. Heavenly Emperor blood dyed the fissure as he suffered heavy injuries.
His gaze was icy cold, for within the fissure, he was greatly suppressed by the seals left by the myriad Supreme Ones, unable to exert his full strength.
However, the mysterious existence wreathed in Chaos Mist was in a similar state. Though he did not retreat, the moment after their clash, he was submerged by endless Forbidden Heavenly Thunder.
This was the punishment for attempting to alter the past and reverse space-time.
Moreover, his opponent was a peerless Heavenly Emperor; the causal force generated was extremely fearsome, and the punishment that descended was far more terrifying than imagined.
Amidst the endless Forbidden Heavenly Thunder, the mysterious existence reappeared, this time revealing his figure. He was a man of peerless divine martial prowess, his face still obscured by Chaos Mist, unclear. Yet his physical body was supremely powerful. The Forbidden Heavenly Thunder that could injure a Supreme One fell upon him, only to produce wisps of green smoke, utterly failing to harm him in the slightest. His flesh was imperishable.
Everyone drew in a sharp breath.
Even the Forbidden Heavenly Thunder could not injure him. How powerful was this person?
The Primordial Heavenly Emperor's expression clearly changed as well, turning somewhat gloomy. This mysterious existence from the future seemed even stronger than imagined, no wonder he dared to utter such words.
Yet he showed little apprehension, stating: "So what if you emerge unscathed this time? The more you act, the greater the causal punishment that descends. No one can truly ignore all this; all will be buried and destroyed!"
The mysterious existence then attacked again, saying: "Just try and see!"
Boom—
Even more fearsome Forbidden Heavenly Thunder was triggered, but the peerless existence from the future disregarded everything, continuously attacking the Primordial Heavenly Emperor!
Without a doubt, this was a peerless battle at the level of the Strongest Emperor, surpassing all previous ones!
"This Heavenly Emperor will see just how much of that boundless causal punishment you, a future being daring to defy the heavens and reverse time to strike at me, can withstand!"
The Primordial Heavenly Emperor also roared. At this moment, his aura began to rise steadily, equally shaking the cosmos across past and present, stirring the rivers of time and space. He was only a step away from completely leaving the fissure and truly emerging. Boundless majestic power manifested, and the River of Time also materialized beneath him.
He feared not the mysterious existence from the future. Even at his strongest, he merely stood in the same domain—both were Strongest Emperors, both were peak-level existences within the Chaos Sea, neither weaker than the other.
Boom! Boom! Boom! Boom! Boom! Boom!
One was the peerless Heavenly Emperor of the Chaos Burial Ground; the other was the invincible being from that mysterious and fearsome blood-stained future. Both were truly invincible Supreme Ones. Their collision now had an immense impact. The River of Time seemed overturned, continuously fracturing and disintegrating—a truly terrifying sight.
Boom rumble rumble—
Simultaneously, boundless, endless Forbidden Heavenly Thunder descended. And not only that, some of the Forbidden Heavenly Thunder transformed into tangible living beings—like True Dragons, Golden Crows, Vermilion Birds, and so on—all Chaos Holy Spirits, each possessing Supreme One-level power, supremely powerful, descending together.
But they only targeted the mysterious existence from the future, for he was the one reversing time to strike. The Primordial Heavenly Emperor was not subject to this.
Undoubtedly, even one as powerful as this mysterious being, akin to a Chaos Heavenly Emperor, was greatly suppressed. Blood trickled from him because the level of their clash involved forces far too profound.
Similarly, the Primordial Heavenly Emperor was not faring well. The stronger he attacked, the greater the suppression from the Sealing Grand Array. One Supreme Imprint after another continuously revived, exerting infinite Supreme might to press down upon him, greatly affecting his strength.
"Damn it!"
The Primordial Heavenly Emperor's expression was gloomy, blood also trickling from the corner of his mouth—due to both the future's invincible existence akin to a Chaos Heavenly Emperor and the Sealing Grand Array.
Naturally, blood also trickled from the corner of the mysterious existence's mouth; he was beginning to suffer wounds.
Finally, both ceased their clash. In truth, the actual collisions were only a few moves, far fewer than imagined, yet the disaster they triggered was already this fearsome.
But even so, the Primordial Heavenly Emperor was still about to cross the fissure, only a few steps away. Once he crossed over, he would be completely unrestricted. Even if the mysterious existence attacked him, the backlash would focus primarily on the attacker, with little affecting him.
"Cease. Attacking me further is useless. You cannot stop my crossing. This Heavenly Emperor will still descend completely, and you simply cannot succeed in hindering me."
The Primordial Heavenly Emperor's words were merciless, but they were also fact. Time could not be reversed; no one could do so without bearing unimaginable consequences. The outcome would be extremely severe; even a Supreme One would perish.
Boom—
At this moment, he had already placed one foot outside the fissure. A Heavenly Emperor's majesty, far more intense than before, swept across the five imperial tomb space-times, the Heaven-Falling Mausoleum, the Heavenly Emperor Realm, even pressing down upon the Emperor War Domain and rushing toward the abandoned Primordial Path of Origin. It caused billions of living beings at the Ninth Heavenly Pass to tremble in terror and prostrate themselves.
The Primal Sin Ancient Beast guarding the Emperor Burial Abyss was startled awake, opening its massive eyes to reveal a deep look of shock and gravity: "In the end, can the unsealing of the Chaos Burial Ground still not be prevented?"
Boom! Boom! Boom! Boom! Boom! Boom!
However, the final step was also the most difficult.
Because the Sealing Grand Array had been revived to its utmost by the Golden Crow Emperor. Those Supreme Imprints emerged one after another, pressing down comprehensively, imposing immense suppression on the Primordial Heavenly Emperor, preventing him from successfully taking that other step for a long time.
"The Beginning of the Primordial, the Origin Imperishable, the Primordial Without End, Ten Thousand Generations Unceasing!"
The Primordial Heavenly Emperor employed a forbidden art of his own creation. Infinite might surpassing the Supreme One level surged forth, causing the suppression from the numerous Supreme Imprints to dim significantly all at once.
