The human army was stunned.
They had originally thought that with the departure of the Formless Sovereign, the Mythical Emperor Domain had completely severed ties and was no longer allied with the human race.
After all, after the human race was suppressed by the Myriad Heavens Emperor Clans and the Immortal Clan, even though there were long-distance spatial gates spanning the Primordial Ancient Domain, the powerful figures of the Mythical Emperor Domain had never descended, let alone offered assistance.
Never did they expect that they would appear at this critical moment.
"Apologies, we are a bit late."
Sovereign Xia Luo, Sovereign Sen Yue, and others spoke.
"It's fine, your arrival is already very good," the reincarnated Emperor said excitedly.
"It should be so. Our Mythical Emperor Domain and the human race are allies," Sovereign Xia Luo said.
Sovereign Tai Xuan had now recovered somewhat after consuming elixirs, his gaze cold and sharp. "Sun Sovereign, you should know that merely having these Ancient Monarchs from the Mythical Emperor Domain come is nothing more than sending them to their deaths."
Sun Sovereign said, "I naturally know. There are also them."
In the starry sky, several more powerful figures emerged one after another.
The world recognized them; among them were Sovereign Hua Xu and other local Ancient Monarchs from the Ten Heavenly Realms Ancient Domain. They had actually all appeared and stood on the opposite side of the Myriad Heavens Emperor Clans and the Immortal Clan, standing shoulder to shoulder with the human race, which was truly astonishing.
However, even so, the total number still did not reach twenty. Compared to the Myriad Heavens Emperor Clans and the Immortal Clan, there was still a huge gap.
"I have also come."
From the Second Heavenly Realm Ancient Domain, a powerful aura of an Ancient Monarch emerged.
The old body of Chixue Longdi, the Crimson-Scaled Giant Dragon, appeared. At this moment, it had already shaken off the troubles of the Dragon Tomb world. Its entire body no longer carried the aura of decay and death seen in the past; on the contrary, it was filled with vitality.
"You carry the aura of Chixue Longdi," the Henggu Monarch said. As an Ancient Monarch from the same Dark Blood Era, how could he not be familiar with Chixue Longdi?
"I am the old body shed by Chixue Longdi during his transformation," the Crimson-Scaled Giant Dragon stated directly.
"It is said that Chixue Longdi was peerless and unparalleled. Back then, he transformed into a pure-blooded True Dragon and was suspected to have truly attained the Emperor realm. Unfortunately, you are merely a discarded husk," Sovereign Tai Xuan said indifferently, not placing the Crimson-Scaled Giant Dragon in his eyes at all. Perhaps only if Chixue Longdi himself were present would this peerless sovereign pay him some attention.
"Perhaps," the Crimson-Scaled Giant Dragon replied lightly, offering no explanation.
Yet no one could truly ignore it, precisely because it was the discarded husk of Chixue Longdi.
Who was Chixue Longdi?
A true supreme powerhouse of the Dark Blood Era, an existence standing at the absolute pinnacle of the entire Ten Heavenly Realms Ancient Domain. He relied on himself to shed his old body, becoming a legendary pure-blooded True Dragon, and dared to call himself "Emperor"—this speaks volumes.
The end of the Dark Blood Era was directly caused in large part by him.
Although Chixue Longdi later disappeared after entering the mysterious Tenth Heavenly Realm Ancient Domain, no one could truly ignore his supreme power and invincibility.
Because, even the Ancient Monarchs of the Myriad Heavens held great wariness toward the discarded husk of that suspected Supreme One-level existence.
Of course, it was only a trace of wariness.
Because the alliance army formed by the Myriad Heavens Emperor Clans and the Immortal Clan held an absolute numerical advantage in terms of Ancient Monarchs.
At this moment, Sun Sovereign looked toward the farthest horizon. It was not the direction of the Tenth Heavenly Realm Ancient Domain, but the First Heavenly Realm Ancient Domain. "I request the Fellow Daoists of the Primordial Ancient Domain to appear."
Roar—
As if responding to Sun Sovereign's call, from the Primordial Ancient Domain, far beyond billions of miles away, one majestic pillar of light after another shot into the sky, appearing in the starry sky.
From the Primordial Ancient Domain, which had once created the terrifying Dark Blood Era, one Ancient Monarch-level Primordial Beast God after another emerged. They possessed colossal bodies capable of bursting the starry sky, traversing the void and shattering countless stars along the way.
"It's them!"
The Henggu Monarch's expression changed. Only those who had participated in the Primordial Beast Disaster of the Dark Blood Era truly understood how terrifying the Primordial Ancient Domain was.
Even back then, there were Ancient Monarchs who, in order to resolve the Primordial Beast Disaster in one fell swoop, ventured far into the Primordial Ancient Domain, but the final result was that they never returned.
Now, with the Primordial Beast Gods of the Primordial Ancient Domain emerging together, it was extremely terrifying.
In the end, over thirty Ancient Monarch-level Primordial Beast Gods crossed over and entered the Ancestral God Pass, causing billions of living beings beyond the Second Heavenly Realm Ancient Domain to tremble with fear, worried that the Dark Blood Era would descend once again.
And they were even more terrified.
No wonder they were able to create the Dark Blood Era that plunged the entire Ten Heavenly Realms Ancient Domain into that prolonged period of darkness. It turned out that the Primordial Ancient Domain actually harbored over thirty Ancient Monarch-level overlords and great terrors.
It must be known that these were not Quasi-Sovereigns, nor Divine Kings, nor Great Powers, but Ancient Monarchs.
Even in the most powerful and glorious Emperor Clans and Immortal Clans of the Myriad Heavens Ancient Universe, few could possess so many Ancient Monarchs.
Often, an entire Chaos Ancient Universe could barely gather this many.
For example, the Sealed World Universe, at its most desolate time, had only a handful of Ancient Monarchs.
The world found it hard to believe that the Primordial Ancient Domain concealed so many Ancient Monarchs.
However, Sovereign Tai Xuan and several other extremely powerful Ancient Monarchs, upon seeing this scene, suddenly felt a shock in their hearts, recalling certain earth-shattering secrets.
Could it be that all these Ancient Monarchs originated from...
Just thinking about that secret was enough to make one's heart race.
They looked toward the Heavenly Eye Divine Emperor in the deepest part of the vast, uninhabited region of the Primordial Ancient Domain, feeling even more terrified.
But it must be said that the appearance of over thirty Ancient Monarch-level Primordial Beast Gods instantly made up for the gap in the number of Ancient Monarchs between the human race and the alliance army.
With Sun Sovereign and the reincarnated Emperor, one could even say they now held the upper hand.
At this time, the other Ancient Monarchs of the Myriad Heavens Emperor Clans and the Immortal Clan who had not yet appeared could no longer sit still. They emerged one after another, adding over a dozen more Ancient Monarchs.
On the Ten Heavenly Realms Ancient Domain, billions of living beings were all terrified.
In order to attack the human race and seize the Heaven-Falling Tomb, the Myriad Heavens Emperor Clans and the Immortal Clan had ultimately brought out over a hundred Ancient Monarchs combined from both sides.
These were not Divine Kings, nor Quasi-Sovereigns.
Any single Ancient Monarch possessed the power to shake half of the Ten Heavenly Realms Ancient Domain. What did it mean for over a hundred Ancient Monarchs to appear together?
Only during the time when the Formless Sovereign was still present and held a grand feast had such a scene occurred, but even that fell somewhat short.
Once these Ancient Monarchs engaged in a major battle, even if they did not use Supreme Emperor Weapons, the final result would not only affect the starry sky but likely cause the entire Ten Heavenly Realms Ancient Domain to be blasted into dust by these Ancient Monarchs.
Boom—
Suddenly, from the deepest part of the Ten Heavenly Realms Ancient Domain, the most mysterious Tenth Heavenly Realm Ancient Domain, a peerless Emperor Palace slowly rose.
The moment the Emperor Palace rose, boundless glorious light shone forth, rushing toward the endless heavens and earth like a curtain of light, separating the starry sky above from below.
Within the light curtain, there was a faint fluctuation of Supreme One-level power.
The Ten Heavens Emperor Palace!
