Back then, that existence trapped within the River of Time was indeed peerless and invincible!
At the very least, powerful as it was, the Origin Will of the Eternal Night Domain was even a significant step stronger in raw power than a Half-Step Overlord. In a one-on-one situation, even a Half-Step Overlord was no match for it.
Yet, back in those days, the Battle Saint Ancestor and others appeared, journeyed to a crucial location within the River of Time, and battled it, ultimately startling that invincible existence.
That invincible existence was originally trapped upon the River of Time, unable to leave. The Origin Will knew this and had always kept an eye on it.
After all, it had often descended upon that crucial location within the River of Time, and by cultivating there, it had eventually developed its own sentience and was born. It knew many things about the River of Time, including how that invincible existence became trapped.
It had always harbored apprehension towards that invincible existence, fearing that one day it might break free and turn against it. Therefore, it could not allow the Battle Saint Ancestor and the others to go and free that invincible being.
But who could have guessed that, although trapped within a severed segment of the River of Time, that invincible existence could still strike, unleashing a blow that overshadowed all ages and was truly peerless!
That single sword strike could sever endless eons, fly out from the River of Time, and cleave its Origin Will body in two.
The Battle Saint Ancestor and the others seized the opportunity to attack, nearly killing it right there.
If it hadn't fled at the critical moment, it likely would have perished on that spot.
The very thought sent shivers down its spine!
However, after the Battle Saint Ancestor and the others took that being away back then, the Origin Will of the Eternal Night Domain no longer had any lingering worries. Naturally, it wasn't afraid now.
Moreover, that crucial location within the River of Time was its important cultivation ground. It naturally would not allow outsiders to set foot there.
Thinking of this, the Origin Will of the Eternal Night Domain's killing intent surged dramatically. It coldly stared at the three Half-Step Overlords, especially Ye Chen, and said, "You humans have pushed me again and again. Today, I shall strike and slay a human Half-Step Overlord, making your race regret it!"
"Eternal Night Without Bounds!"
The Origin Will of the Eternal Night Domain roared. The dark Upper Realm suddenly soared into the sky, releasing a layer of world-light that enveloped Ye Chen. Countless beams of dark light also shot towards Ye Chen.
Each of these beams of dark light resembled a starry river, endless and infinite, yet also containing boundless slaughtering power, enough to instantly kill a Ten Thousand Ancient Giant!
Without a doubt, this was the Origin Will of the Eternal Night Domain's trump card. Once unleashed, it posed a tremendous threat even to Half-Step Overlords!
Donghuang and the Desolate Heaven Demon Lord were startled and wanted to rescue Ye Chen, but the Origin Will of the Eternal Night Domain blocked them, giving the two Half-Step Overlords no chance.
Ye Chen was directly enveloped within this dark Upper Realm, under constant attack by endless dark light.
Of course, Ye Chen himself was immensely powerful. Protected by the Cosmic Phantom, even the dark light could not breach it for the moment. However, this dark light was also formidable, constantly eroding the Cosmic Phantom. It wouldn't be long before it truly broke through.
Naturally, Ye Chen was far from afraid. Ultimately, besides the Cosmic Phantom, his Chaos Universe Body was still incredibly strong. This dark light might not necessarily harm him.
At this moment, however, he paused. Ye Chen felt these streams of dark light and even consciously guided them, bringing hundreds of streams before him. Under the powerful suppression of the Cosmic Phantom, they halted in front of him.
Ye Chen's eyes were as profound as the Chaos Sea. He observed these dark lights. A brief moment of scrutiny yielded great gains, allowing him to perceive various mysteries. Then, he actively absorbed these dark lights into his body.
A moment later, a trace of pleasant surprise appeared on his face. He murmured to himself, "Indeed, this dark light is very similar to the power of the Origin Burial Lord from back then. It's like the opposite of the Chaos Great Dao—Chaos Darkness. It can allow my Chaos Great Dao to approach Great Perfection, achieving a different kind of completion."
Back when he was still an Extreme Realm Quasi-Giant, he had followed the Battle Saint Ancestor and others to campaign against the Origin Burial Lord, experienced its attacks, and even obtained one of its heads, which contained a dark thunder pearl akin to an origin thunder pearl. Its essence was very similar to this dark light.
It also contained a Chaos Origin, but it was a Chaos Origin completely opposite to the one he cultivated and the one of the Chaos Sea.
It was as if the Chaos Origin of the Chaos Sea was light, while the Chaos Origin of the Eternal Night Domain and the Origin Burial Lord was darkness—the opposite side.
In the past, Ye Chen had never been able to understand the distinction between the two,not understanding why the Origin Burial Lord's power possessed the other side of the Chaos Origin.
Now, he finally understood completely. He also realized why, throughout the ages, no one had been able to achieve the Chaos Great Dao, and why Tai Sheng Huang's comprehension of the Chaos Dao reached the perfection stage of 9,999 out of 10,000,continuously / remained unable to take that final ten-thousandth step.
It wasn't because Tai Sheng Huang did not prove his Dao and become Emperor through the Chaos Great Dao. That was one reason, but its true impact was not as great as the world imagined.
Rather, the Chaos Great Dao of the Chaos Sea was inherently defective.
Yes, defective—only half of the true Chaos Great Dao.
The final ten-thousandth part was the other half of the Chaos Great Dao.
That other half was absent, had never existed, which is why no one throughout the ages could prove their Dao and become Emperor through Chaos!
Even if Ye Chen could eventually evolve his Chaos Small Universe into a complete Chaos Ancient Universe in the future, he could not make the Chaos Great Dao reach complete Great Perfection. It would forever remain at the perfection stage of 9,999 out of 10,000.
The Origin Burial Lord and the Eternal Night Domain both originated from the Origin Land, possessing the other half of the Chaos Great Dao.
The reason Eternal Power could make Ye Chen's Chaos Great Dao more complete was because true Eternal Power contained the Great Perfection Chaos Great Dao, thus gradually completing Ye Chen's so-called perfect but defective Chaos Great Dao.
Similarly, although the dark power of the Origin Burial Lord and the Eternal Night Domain wasinferior to Eternal Power, it also originated from the Origin Land and contained the Great Perfection Dao. Although it wasn't the pure Chaos Great Dao, all the myriad Daos of the world stemmed from the Chaos Great Dao. Therefore, it could also, to a certain extent, complement his Chaos Great Dao.
Thus, it played a certain role in helping Ye Chen's Chaos Great Dao progress towards greater completion.
Ye Chen suddenly attained enlightenment. His gaze seemed capable of piercing through the entire dark Upper Realm, piercing through the Eternal Night Domain, overlooking the entire Chaos Sea. He murmured to himself, "A defective Chaos Sea, missing the other half of the Chaos Great Dao. Why was it created? Why was it destroyed and then created again? What exactly is the Origin Land?"
