"Shidai, you truly live up to being the most fearsome hidden hand throughout the ages. Back then, you tempted the giants of various epoch eras to cross time and space, reverse the River of Time, and strike against my Sealed Boundary Universe, forcing me to sever a segment of time to prevent their descent."
"It also left me with no capacity to attend to other matters, allowing you to target my Sealed Boundary Universe. I must admit, you are indeed terrifying."
The Heavenly Emperor spoke slowly, revealing the secrets of the past. Although these were hardly secrets to the Myriad Heavens Supreme Rulers, hearing them from the Heavenly Emperor's own mouth was still profoundly shocking.
To restrain the Heavenly Emperor, Shidai alone had persuaded the supreme existences of various epoch eras to take action against him. Otherwise, the Heavenly Emperor would not have been so powerless to attend to other matters, nor would the Sealed Boundary Universe have fallen into silence and extinction.
Shidai, the most ancient and powerful existence of the alien race, hovered within the ancestral temple at the center of the universe's origin. His form was indiscernible, his aura isolated across countless ages and worlds, as if he existed beyond past, present, and future, a being of complete transcendence.
He slowly spoke, his voice unique, carrying the resonance of the myriad Daos. It seemed aged, yet clear, even childlike, yet ultimately ordinary. "Heavenly Emperor, in those days, few in the world could hinder me. You were one of them. As long as you were stopped, it was no problem for my Ancient Universe to shatter the Sealed Boundary Universe."
The Heavenly Emperor was one of the greatest obstacles to the alien Ancient Universe's invasion of the Sealed Boundary Universe.
As for the others, even if there were still the Tai Sheng Huang, the Space-Time Great Emperor, the Battle Saint Ancestor, the Samsara Great Emperor, and other Strongest Emperors, the combined power of the alien Ancient Universe and its other Strongest Emperors was sufficient to deal with them.
Moreover, the Great Mythical Extinction of the Sealed Boundary Universe back then was not as simple as just the alien Ancient Universe making a move.
Even the Battle Saint Ancestor of that time had faced Supremes beyond the alien Ancient Great Emperors, such as a supreme immortal from the Primordial Immortal Realm...
There was far, far too much involved.
The Heavenly Emperor seemed about to speak, but at that moment, on the forgotten tributary of the River of Time, countless terrifyingly boundless Supreme Emperor shadows suddenly manifested between heaven and earth, so grand and immeasurable that the stars of the myriad heavens seemed as insignificant as dust.
They were descending by treading upon the River of Time, their voices carrying the heartless tone of the Heavenly Dao: "Heavenly Emperor, your opponents are us."
They also saw Shidai and said, "Shidai, it's good that you are here too. Let us join forces today and slay the Heavenly Emperor."
The human side's expressions changed. Slay the Heavenly Emperor?
The Heavenly Emperor remained composed. He took a deep look at the ancestral temple floating within the origin of the alien universe, and at Shidai, as if sighing inwardly.
"What a pity!"
At this moment, the Heavenly Emperor's aura instantly surged to its absolute peak, causing the River of Time to explode and break into several segments. A section of the river was cut off, preventing the supreme existences from the upper stream, from various epoch eras, from descending.
Boom—
The Heavenly Punishment Imperial Sword slashed out, directly severing the tributary of the River of Time, isolating space-time, affecting past, present, and future.
Carrying the severed arm of Zu Gu Da Di, which was bound, he followed that tributary of the River of Time as it gradually faded, destined to be forgotten once more. Only the Heavenly Emperor's voice continued to echo forth: "From this day forward, I shall first sever those of you who dare to cause chaos. On the day I return, I shall sever Shidai!"
Boom—
The tributary completely vanished, no longer visible. Only the Heavenly Emperor's domineering voice continued to reverberate.
Within the Chaos Sea, Tai Sheng Huang, the World Ancestral Tree, Zu Gu Da Di, Shidai, and others remained.
Zu Gu Da Di had suffered terrible injuries, affecting both his form and spirit. Without sufficient time, it would be difficult to recover fully, and this 'sufficient time' likely meant an entire era, or even an epoch...
However, he gazed coldly at Tai Sheng Huang, the World Ancestral Tree, the Supreme Human Emperor, the Formless Monarch... and said, "Very well. Today, I shall conveniently eliminate these remnants of the Sealed Boundary Universe as well, directly occupy the Sealed Boundary Universe, and retrieve that thing."
"Is that so?"
Tai Sheng Huang's expression was icy, fearless. "Let's see how your alien race intends to annihilate my Ancient Universe!"
The World Ancestral Tree swayed. The Supreme Human Emperor held his holy sword. The Formless Monarch grasped the Great Wall, all fearless.
Within the Ten Heavens Ancient Domain, the Sun Great Emperor also held the Sun Emperor Bell, fully awakened, facing them with an indifferent expression.
All ages watched. The Myriad Heavens Supreme Rulers also halted their advance towards the Ten Heavens Ancient Domain, focusing on this scene.
Boom—
At this time, within the Primordial Immortal Realm, several auras of peerless Immortal Kings erupted, shaking the Chaos Sea.
"Enough! The Chaos Ancient Universe cannot be destroyed. Do not forget the agreement!" an Immortal King spoke.
"Tai Shi, Hun Shi, Pan Dao—"
Gazing at the several peerless Immortal Kings within the Primordial Immortal Realm who were releasing their Immortal King auras, Zu Gu Da Di's expression turned gloomy.
Back then, the alien Ancient Universe had almost succeeded in completely seizing the entire Sealed Boundary Universe. It was only due to the intervention of the Primordial Immortal Realm that their efforts came to naught.
Today, the Primordial Immortal Realm was also intervening, which greatly displeased Zu Gu Da Di.
Within the alien Ancient Universe, several ancestral temples floated, emanating world-ending auras capable of destroying epochs, confronting the others.
"Alien race, do not bring ruin upon yourselves!"
An Immortal King shouted lightly, his immortal Dao aura peerless, illuminating the myriad heavens, inspiring awe even in the Myriad Heavens Supreme Rulers.
"Hmph, do not think my Ancient Universe fears the Primordial Immortal Realm!" Zu Gu Da Di snorted coldly, maintaining the confrontation.
Several Strongest Emperors and Immortal Kings from the two most powerful Chaos Ancient Universes within the Chaos Sea confronted each other. The intensity of their auras surpassed all imagination. Even the Myriad Heavens Supreme Rulers paled, knowing that if such beings truly took action, it could very likely lead to the terrifying consequence of a great epoch upheaval.
"Hahaha, very well! Today, alongside fellow Daoists from the Primordial Immortal Realm, let us exterminate all alien Great Emperors!" Tai Sheng Huang laughed heartily, his domineering aura unparalleled. His strongest Emperor might wantonly spread, causing the thirteen alien Ancient Great Emperors to change expression.
"Who slays whom remains to be seen," Zu Gu Da Di sneered. His injured Emperor body had already recovered, though his aura still seemed relatively weak.
The two Chaos Ancient Universes confronted each other but ultimately did not take action, deeply aware of the immense consequences. Once they moved, it would thoroughly affect the entire Chaos Sea, causing too great a disturbance, shaking past and present.
Shidai remained calm throughout, watching everything without taking action. This secretly allowed the other Strongest Emperors and Immortal Kings to breathe a sigh of relief, knowing that if Shidai acted, it likely would not end so peacefully.
Due to the intervention of several peerless Immortal Kings from the Primordial Immortal Realm, in the end, Shidai, Zu Gu Da Di, the Cyan Light Great Emperor, and all other alien Ancient Great Emperors withdrew, returning to their Chaos Ancient Universe.
However, before returning to the alien Ancient Universe, Shidai suddenly paused, looking over as if glancing towards the Ten Heavens Ancient Domain.
No one paid much attention to Shidai's gaze, assuming he was merely looking at the 'Supreme' immortal fate left behind by the collective Myriad Heavens Supreme Rulers.
Even Shidai would be moved by it.
However, within the Supreme Ancient Domain, Ye Chen's scalp suddenly prickled, revealing an extremely rare look of horror.
Because he felt that Shidai seemed to be looking at him.
That gaze traversed the Chaos Sea, crossed endless chaotic space-time, feeling so real, so clear.
It was not cold and heartless, but carried a special emotion, complex, impossible to fully discern. Yet within it, there seemed to be a trace of... gentleness!
Just as Ye Chen wanted to confirm it, Shidai had already vanished.
Tai Sheng Huang watched coldly until all the alien Ancient Universe's Great Emperors had truly retreated. He then gave a slight nod towards the several Immortal Kings of the Primordial Immortal Realm before his majestic, chaotic figure gradually faded from the River of Time.
He could not remain on the River of Time forever. There were extremely important matters on the Path of Origins.
Moreover, someone was targeting them; otherwise, they would not have been forced to the point where even the Battle Saint Ancestor had to appear.
Finally, he acted, sending the Qiankun Eight Trigrams Mirror carrying the might of a Strongest Emperor towards the Ten Heavens Ancient Domain, further empowered by the World Ancestral Tree's space-time might. Instantly, the Great Dao imprints of the Myriad Heavens Supreme Rulers were forcefully suppressed, and the world black hole of the Ten Heavens Ancient Domain slowly began to repair itself.
Seeing this, the Myriad Heavens Supreme Rulers could only retreat helplessly and return.
"Sun!"
"Formless!"
The Sun Great Emperor and the Formless Monarch, two human Supremes, smiled at each other across the Chaos Sea before each turned and left.
The World Ancestral Tree returned to the Sealed Boundary Universe. The Human Emperor also gave a slight nod to the Sun Great Emperor before his expression turned slightly solemn as he returned to the universe. At this moment, several terrifying Supreme-level fluctuations had risen, requiring their attention.
