At this moment, the three were undergoing the initial stage of fusion and refinement, reaching the most critical juncture.
Only when flesh and bone truly merged would the brand new Chaos Saint Body be born.
Similarly, this step was also extremely perilous.
Because the three alien Monarchs still possessed over a hundred million strands of Monarch Rules that had not yet been integrated into the Chaos Saint Bone. Such an immense and rich trove of Monarch Rules was something Ye Chen would not simply abandon; he had to fuse them into his flesh and blood.
Flesh and blood, unlike bone, were not as solid and indestructible, unable to contain such an enormous quantity of Monarch Rules. However, refining over a hundred million strands was still possible.
Doing so would make the Chaos Saint Body even more indestructible and invincible. Its pure physical power would become terrifyingly greater than that of a Monarch, perhaps even reaching a level comparable to an Eternal Monarch like Tai Chu, which would not be an exaggeration.
Of course, undertaking this carried immense risk.
The slightest misstep could cause both flesh and bone to fail, undoing all previous efforts.
During the refinement process, the Undying Emperor Medicine, the Ancient Life Tree, and the World Tree all flew out, merging into the new Chaos Saint Body. Countless roots burrowed into every inch of flesh and blood, aiding the refinement.
Especially the Undying Emperor Medicine and the Ancient Life Tree continuously released endless vitality, allowing the Chaos Saint Body to endure crisis after crisis.
The World Tree, meanwhile, generated layers of spacetime power, sealing the surroundings and forcefully propelling the fusion and refinement.
Time flowed on, year after year, a decade passing like a day, a century flying by like an arrow...
With the assistance of these various methods, the flesh of Ye Chen's Saint Body continuously grew. Chaos light suffused every corner of his flesh, empowered by the imprints of hundreds of millions of Monarch Rules, layered upon layer, making it appear increasingly indestructible and immortal.
It was foreseeable that in not many more years, the Chaos Saint Body would truly complete its fusion and refinement.
That day would also mark Ye Chen's emergence from seclusion.
On another front, the Primordial Small Universe and the embryonic Upper Realm had also expanded considerably...
...
This year marked the first millennium since Ye Chen left the Pangu Universe.
A thousand years, an eternity in the annals of time.
Over these years, since Ye Chen's return centuries ago, when he led the powerful experts of the Pangu Universe to annihilate all alien armies outside the Tenfold Emperor Passes, and even used the Monarch Tribulation to charge in and out, causing a generational crisis within the alien Ancient Universe...
All alien armies within the Pangu Universe had been completely eradicated.
The Pangu Universe enjoyed a rare millennium of peace.
It was firmly believed that, for at least the next ten thousand years, the alien races would be unable to recover.
After a millennium of recuperation and growth, the Pangu Universe, compared to a thousand years ago, could be described as teeming with talent, with geniuses emerging one after another, the myriad Daos flourishing, and the Heavenly Dao perfected, surpassing the past by an immeasurable degree.
However, the anticipated ten-thousand-year peace did not continue.
BOOM—
Suddenly, at the Tenfold Emperor Passes of the Pangu Universe, the heavens cracked and the earth split. An immeasurable, terrifying power abruptly descended, crashing against the Tenfold Emperor Passes.
The boundless Chaos Sea exploded layer by layer, an unbelievable, utterly terrifying sight.
Visible to the naked eye, the phantom of an immeasurably vast and majestic great universe appeared, shaking the Tenfold Emperor Passes and alarming the entire Pangu Universe.
Supreme existences had arrived, and not just one—thirteen in total, shaking the ancient and modern eras, their Emperor might immeasurable, their Sovereign aura stirring past and present!
These were thirteen Ancient Emperors, clad in imperial robes, crowned with diadems, their Sovereign majesty causing the myriad Daos to retreat. Each was peerless, looking down from on high, directly facing the Tenth Emperor's Pass.
Behind them, within the phantom of the vast great universe, countless, innumerable armies gathered, dense and endless, far exceeding billions.
A fearsome cosmic army assembled, led personally by multiple Ancient Emperors, intending to attack the Pangu Universe, shaking the Chaos Sea.
"So this is the Pangu Universe?"
One Ancient Emperor spoke. Infinite purple Sovereign aura cascaded from him, obscuring his true features. Only his Sovereign majesty pervaded, forcing the myriad Daos to retreat, chaos itself unable to approach. His Sovereign Dao stood supreme, evolving a domain of Sovereign Dao where he alone was invincible!
Another Ancient Emperor also spoke, his body shimmering with golden Sovereign aura like a golden heavenly sun, setting him off as peerlessly supreme: "It is said this Pangu Universe is extraordinary. It reached its peak of prosperity only in the previous epoch, ranked among the most powerful Chaos Ancient Universes of the Chaos Sea, possessing multiple Giants of All Ages and numerous Emperor and Sovereign Supremes. Truly remarkable."
"Heh, that is merely the past. Gazing along the river of time, only our Chaos Burial Ground endures eternally, with Heavenly Emperors immortal and Ancient Emperors peerless. Today, let alone this Pangu Universe which has already declined, even at its peak, facing our Chaos Burial Ground, it would tremble and submit, be shattered and sunk!"
"Kill!"
"Kill!"
"Kill!"
...
One peerless Ancient Emperor after another awakened, displaying overwhelming Sovereign majesty, directly attacking the Tenth Emperor's Pass.
Terrifying Supreme Sovereign attacks, a joint assault by multiple Emperors, with immeasurable Supreme Emperor Principles flooding the skies and earth, submerging the Tenth Emperor's Pass.
Although Ancient Emperors were proud, being Great Perfection Supremes, they also understood the extraordinary nature of this Tenth Emperor's Pass. One or two Ancient Emperors could not possibly breach it; only a joint attack by multiple Emperors could forcefully break it open.
Hum—
Upon the Tenth Emperor's Pass, arrays personally laid down by the Human Emperor were inscribed, layer upon layer, overlapping. Combined, they were equivalent to the Quasi-Giant Level. Now, facing this heaven-shaking crisis, they autonomously activated to block.
The Chaos Sea exploded!
Even over one-fifth of the Chaos Sea territory surrounding the Pangu Universe trembled violently.
It must be understood that a Chaos Ancient Universe was vast and boundless, its diameter incalculable in billions of miles. The Chaos Sea territory enveloping the Pangu Universe was naturally astonishingly expansive. Yet, over one-fifth of it was shaken—imagine how terrifying that was.
The thirteen Ancient Emperors acted, suppressing everything as they looked at the Tenth Emperor's Pass, their eyes narrowing slightly.
The Tenth Emperor's Pass had developed terrifying cracks, but it ultimately withstood the assault, not completely collapsing, because the Quasi-Giant Level grand array left by the Human Emperor had blocked it.
However, this single strike had caused the Quasi-Giant Level grand array to dim considerably.
It was clear that sustained attacks two or three more times would inevitably shatter the Quasi-Giant Level grand array completely.
"What a Pangu Universe! To think it still has such an indestructible Quasi-Giant Level grand array guarding the Tenth Emperor's Pass. Truly extraordinary. But how long can it hold?"
An Ancient Emperor sneered, joining the others to attack the Tenth Emperor's Pass repeatedly.
At this time, the Ancient Sovereigns guarding the Tenth Emperor's Pass of the Pangu Universe were alarmed. There was one Monarch and seventeen Ancient Sovereigns.
Witnessing the terrifying lineup outside the Tenfold Emperor Passes—the thirteen peerless Ancient Emperors spanning the firmament, each supremely invincible, let alone thirteen coexisting—it was utterly hopeless.
If not for the Quasi-Giant Level grand array left by the Human Emperor in the past protecting them, not only the Tenth Emperor's Pass, but the other nine passes along with all those guarding them would have been annihilated in the first instant, utterly ceasing to exist.
