Especially the Heavenly Emperor posed the greatest threat to Zu Gu Da Di.
The three Heavenly Emperor weapons were all specifically targeted against Supreme Ones. The Heaven-Punishing Emperor Sword, the Heaven-Binding Chains, and the Heaven-Burying Stele—which one was not forged specifically to counter Supreme Ones who rivaled the Heavenly Dao? Because of the Heavenly Emperor, they could even target giant existences at the level of Strongest Emperors and Immortal Kings.
With the Heaven-Punishing Emperor Sword unleashed, even the indestructible, calamity-proof body of the Demon Emperor was wounded, bearing several terrifying wounds deep enough to reveal bone, permeated with terrifying supreme Emperor Dao laws that were difficult to heal.
The Heavenly Emperor alone was enough to pose a huge threat to him, let alone Tai Sheng Huang, the World Ancestral Tree that was the Time-Space Great Emperor's true form, the Supreme Human Sovereign suspected to be the reincarnation of the Samsara Great Emperor, and the Formless Monarch who arrived wielding the First Emperor of Qin's weapon, the Great Wall.
With such a lineup, given enough time, they truly could slay him, a Strongest Emperor.
"Could it be that today we will truly witness the slaughter of a Strongest Emperor?"
The Supreme Ones of the All Heavens were all trembling with fear.
Today, the successive thunderous suppression and slaying of two ancient Great Emperors by Tai Sheng Huang and the Heavenly Emperor was already a major event that shook the entire Chaos Sea. If a Strongest Emperor were to be slaughtered, it would undoubtedly shake the past, present, and future to their core, with an immeasurably huge impact.
Strongest Emperors were the pinnacle existences of the Chaos Sea, surpassing Supreme Ones.
For ordinary Ancient Chaos Universes, only one Strongest Emperor could be born throughout entire Era Epochs. Looking across the entire Chaos Sea, only special Ancient Universes like the Primordial Immortal World, the Alien Ancient Universe, the Sealed Realm Universe, and the Chaos Burial Ground could give birth to multiple Strongest Emperors.
But even then, they were few and far between, countable on one's fingers.
For such powerful Ancient Chaos Universes, Strongest Emperors were still indispensable supreme existences. After all, giving birth to a single Strongest Emperor was truly, truly difficult. Throughout an entire Era Epoch, the Chaos Sea might not see one born.
Today, if Zu Gu Da Di were slaughtered, it would absolutely be a shocking event, surpassing all others.
It might even very likely cause the entire Era Epoch to end prematurely, driving the Alien Ancient Universe to utter madness.
There was no need for doubt; a Strongest Emperor absolutely possessed such importance. Even a single Strongest Emperor could be decisive for the life and death of an ordinary Ancient Chaos Universe.
"Ah—"
Zu Gu Da Di roared, struggling desperately. The other thirteen alien ancient Great Emperors also continuously attacked, trying to cross the severed River of Time to rescue him.
A Strongest Emperor like Zu Gu Da Di absolutely could not die.
The Heavenly Emperor swung his sword again. The Heaven-Punishing Emperor Sword, once unleashed, severed space-time, severed the years, as if eternal, dividing Zu Gu Da Di and the other alien ancient Great Emperors on two sides.
It contained boundless Emperor Dao laws and the mighty power of endless ages, impossible to cross, making the fourteen alien ancient Great Emperors feel a sense of powerlessness.
The Heavenly Emperor was too powerful, overlooking epoch after epoch, not something these Supreme Ones could contend with.
If not a Strongest Emperor, if not an Immortal King, who could rival him?
Across the Ancient Chaos Universes of the All Heavens, those Strongest Emperors and Immortal Kings watched all this coldly, making no move. Yet, flickers in their gazes seemed to reveal shock as well.
Because the impending fall of a Strongest Emperor was a being of the same level; even they could not treat it lightly.
"Slay him!"
The Heavenly Emperor, majestic and the First Emperor of the Sealed Realm, brandished the Heaven-Punishing Emperor Sword.
Tai Sheng Huang wielded the Qiankun Bagua Mirror.
The Supreme Human Sovereign held the Human Sovereign Holy Sword, with the Human Sovereign Pagoda hovering above his head. Terrifying samsara power permeated the air as he also attacked.
The Formless Monarch revived the Great Wall, as if the First Emperor of Qin himself had struck, suppressing the myriad realms of the All Heavens.
The World Ancestral Tree severed the ages of space-time, continuously draining Zu Gu Da Di's power.
Boom—
Zu Gu Da Di suffered unprecedented heavy damage. His Emperor body was split in two, bloody holes pierced through front and back, and immeasurable demonic blood was devoured.
His indestructible Emperor soul also suffered a terrifying impact.
Facing the assaults from the Sealed Realm Universe's Strongest Emperors or their weapons, if not for Zu Gu Da Di being a Strongest Emperor with life force powerful enough to be indestructible through the ages, any other Emperor-level Supreme One or supreme immortal would have been annihilated.
But even so, he was utterly crippled, facing the crisis of falling, a tragic sight.
Boom—
A sudden change occurred. From within the Alien Ancient Universe, several supreme auras surpassing Supreme Ones erupted. The other Strongest Emperors could no longer sit still; they made their move. Boundless demonic might blotted out the sky and sun, pouring into the River of Time.
Several ancestral temples rose and fell, carrying an aura of eternal indestructibility, rescuing Zu Gu Da Di.
Even the Heavenly Emperor, Tai Sheng Huang, and the World Ancestral Tree could not completely stop it.
Because among them was Shidai's intervention.
Ye Chen's gaze suddenly sharpened, because he saw a masked Great Emperor—precisely that Cyan Light Great Emperor who had helped him back in the Mythical Epoch. He was indeed also a Strongest Emperor, standing shoulder to shoulder with the other Strongest Emperors of the Alien Ancient Universe, his status remarkably high.
"Shidai!"
On the tributary of the River of Time, the Heavenly Emperor remained indistinct, yet everyone could sense that this First Emperor of the Sealed Realm was looking at Shidai, who resided within the ancestral temple floating at the core of the Alien Universe's origin. His gaze carried a solemnity not even present when facing Zu Gu Da Di.
It was conceivable that an existence like Shidai made even the Heavenly Emperor solemn, never daring to be careless or underestimate him.
At the same time, Tai Sheng Huang's arrogant demeanor turned restrained, the World Ancestral Tree grew quiet, and the Supreme Human Sovereign and the Formless Monarch all acted as if facing a formidable enemy.
"Heavenly Emperor!"
Shidai slowly spoke. He was indistinct, utterly mysterious, sitting cross-legged within the ancestral temple, motionless, yet overlooking the entire Chaos Sea, making all the Supreme Ones of the All Heavens feel reverence.
Because Shidai's name was too renowned, too powerful.
He had once caused the Eight Desolates Ancient Universe to attack the Primordial Immortal World, leading to its destruction, and had caused the Great Cataclysm of the Sealed Realm Universe's Mythical Age. He could be called the most terrifying hidden hand throughout the ages.
The Strongest Emperors and Immortal Kings of the other Ancient Chaos Universes all grew much more solemn upon seeing Shidai's appearance.
Shidai's fearsomeness was undeniable.
Back then, the Strongest Emperor of the Eight Desolates Ancient Universe, Great Emperor Hantian, had also indirectly fallen because of Shidai.
Hum—
Suddenly, Ye Chen felt the moon mark between his eyebrows tremble slightly, as if sensing a subtle connection, which shocked him.
But soon, this sensation quietly vanished, disappearing without a trace.
This left Ye Chen puzzled and suspicious.
In the present age, looking across epoch after epoch, these two could absolutely be called the most pinnacle existences.
Heavenly Emperor! Shidai!
They gazed at each other. The terror of their gazes even caused the River of Time to tremble, showing signs of fracturing.
It was conceivable just how fearsome these two supreme giants were.
