Cao Ya knew that the universe outside of the [Desolate Era] and the chaotic universe would not be discussed for the time being.
A chaotic universe, with boundless space, is composed of countless realms, alien universes, and various dangerous and perilous places.
The realm contains boundless territories, and each territory contains anywhere from tens of thousands to hundreds of thousands of chaotic worlds.
Since the other universe is a geographical unit at the same level as the domain, naturally, the relevant divisions are almost identical.
Of course, different universes and realms vary in size and cannot be generalized.
However, the other universe is special because it possesses primordial power, which can be refined by powerful emperors to become the masters of the other universe!
The realms, however, lack this; they are supplied with the primordial power of all the Great Daos by the entire chaotic universe…
Even ordinary supreme beings would be far from being able to refine the chaotic universe!
The Lord of another universe, normally speaking, surpasses ordinary rulers and can be considered a super ruler!
But that refers to the best among the Eternal Emperors—the Ruler, who obtained great fortune, was able to refine a vast alien universe, and mastered the immense power of origin, thus possessing such great power.
The Lord of Destruction is not a true ruler in essence. Although he can surpass rulers by relying on the other universe, he is still inferior to other rulers of other universes.
It's like being somewhere between a ruler and a super ruler, a rather awkward position!
But no matter what, the power of the Lord of the Destruction Divine Court is strong enough that any ordinary ruler with malice is courting death!
Because the Lord of the Divine Court completely controls this alien universe, he is an existence akin to the Heavenly Dao. Therefore, he can sense the entry and exit of any living being, and whether or not to intercept them depends entirely on his will.
It is obvious that the Black Emperor's methods, whether due to prior notice or trust, involved destroying the Lord of the Divine Court without any obstruction, allowing Cao Ya to traverse the spacetime vortex and arrive in another universe.
In fact, Cao Ya spent several years inside the time vortex before finally crossing it!
Furthermore, the cosmic passages are distorted, and time, space, and various rules are all in disarray. Even an ordinary Dao Lord would suffer from physical and spiritual discomfort, and it is not impossible for him to fall seriously ill.
But Cao Ya naturally had no problems and adapted very well, even having the leisure to think about why the Black Emperor sent him into the other universe.
"Is it simply optimism, or..." Cao Ya pursed his lips. From the Black Emperor's words, he could be basically certain that it was his practice of [Dao Spreads Across the Universe] that, due to the uniqueness of his sword intent, alarmed this ancient star lord and the ruler among the eternal emperors of another universe, thus causing him to appear and bestow fortune upon him.
However, Cao Ya had no intention of going to the other universe. He was dissatisfied with the Chaos Era, which had a long lifespan. He could cultivate slowly and reach the Eternal Realm, but reaching the Fourth Step Dao Lord was still not a big problem.
"The opportunity the Black Emperor spoke of within the origin of the other universe... could it be the inheritance of the Sword Dao Master?"
Cao Ya's eyes twitched, somewhat annoyed.
His path is not the way of the sword. It's just that his counterparts in the universes such as [Peerless One] and [Immortal Gourd] have mastered swordsmanship to a high degree, so he occasionally tries it out, hoping to draw inspiration from it and improve his own Bright Light Path!
At present, Cao Ya has no intention of changing his path. As the Dao Lord of Life and Death, he is opening up his own path. Every step is extremely dangerous and cannot be taken lightly!
The Path of Bright Light is Cao Ya's foundation. Even though he has entered the system space once, he still thinks that he should first perfect the Path of Bright Light so that it can be eternal and have an endless lifespan before he can explore other paths!
Therefore, even though he possessed a great deal of extraordinary knowledge, including seven-star, six-star, and five-star levels, Cao Ya's actions were still merely seeking inspiration, without any intention of pursuing the path of swordsmanship, sabers, or flames.
There's no way around it; pioneering a new path is far too dangerous. Ninety-nine percent of Dao Lords will fail!
Even with all the opportunities Cao Ya has, he must not slack off. He should first thoroughly deduce the Mingguang Road before discussing other paths.
Moreover, this single avenue leads directly to the Supreme Being!
Although it may not succeed, at least there is a sliver of hope, it's not a zero probability.
The most important point is that Cao Ya does not believe that he is a peerless genius who would be hard to find even once in millions of chaotic eras!
Having recognized his own limitations, Cao Ya will not be overly ambitious. He will seize the present to have a future!
"The legacy left behind by the rulers or other emperors in the origin of the other universe before their death is none of my concern."
Cao Ya calmed down. Since the Black Emperor had no ill intentions, the Lord of the Destruction Divine Court certainly wouldn't target him either.
When the time comes, I will venture into another universe and try to find out the whereabouts of various Dao-harmonizing treasures.
"My combat strength is extremely high; I can fight against, or even annihilate, a top-tier emperor!"
"But when we reach the edge of the fourth step of the Dao Integration, the path to eternity will still be fraught with difficulties."
"And Dao-merging treasures can undoubtedly increase my chances of merging with the Dao!"
Cao Ya then realized that many of his own experiences had insights into the bright side. If he were to comprehend these insights, aside from other matters, perfecting the Path of Bright Light to the level of the fourth-step Dao Lord wouldn't be too much of a problem.
Therefore, for him, the biggest problem at present is the difficulty of achieving the Dao, which is close to certain death!
"An alternate universe can contain a God-Destroying Divine Court, and there are quite a few Eternal Emperors. Obviously, it certainly has no shortage of Dao-Merging Treasures!"
Cao Ya became excited.
Previously, he always stayed in the Bright Light Domain, at most wandering around the surrounding areas, and would not travel to more prosperous territories, feeling that it was too dangerous.
Despite such a significant increase in power, he showed no signs of panic even after arriving in another universe.
Suddenly, Cao Ya's heart skipped a beat and he tensed up!
If he remembered correctly, Ji Ning and the others went to the other universe because they received the Ancient Domain Token bestowed by the ruler of Mangya Kingdom, which prevented them from being crushed by the power of origin and becoming fragments.
"There's not a trace of the Ancient Domain Token on me!"
Cao Ya was tense, but quickly relaxed. His primordial power was completely controlled by the Lord of the Divine Court. After the Black Emperor reminded him, he relaxed the restrictions a bit and allowed him to go deep into the ancient domain in the core area of the alien universe alone without holding the Ancient Domain Token. There was no problem with that.
Although it is called the core, the ancient domain is actually vast and boundless, the size of countless territories, and contains a considerable number of chaotic worlds.
If we're talking about the exact numbers, it's definitely more than trillions!
Among them, there are certainly many powerful figures, not to mention Dao Lords!
Compared to many experts, Cao Ya is naturally not conspicuous. As long as he is cautious enough, he should not encounter any fatal crises!
Years later, Cao Ya stepped out of the cosmic passage and finally arrived in another universe.
He looked around. Chaotic mist surged, and in the distance, a huge fireball floated in the void, reaching far and wide, radiating endless light!
Upon leaving the Flame Dragon Domain for the first time and arriving in another universe, Cao Ya carefully sensed the surroundings and couldn't help but marvel.
"Like the Flame Dragon Domain, it has various Great Dao origins, such as metal, wood, water, fire, earth, wind, thunder, light, darkness, time, and space."
Cao Ya nodded silently. The origin of the Great Dao is like a series of foundation stones that support the alien universe!
In fact, whether it is a realm or an alternate universe, they are all enveloped by the chaotic universe, and their various laws are naturally quite similar.
Only by going to different chaotic universes will differences arise, making it impossible to use the divine power of the Great Dao.
Of course, other universes are mostly created by powerful beings and contain their insights. Even though their origin is still the chaotic universe, their manifestations in certain aspects will inevitably differ.
"The Great Dao of this alien universe is much more ferocious, unlike the Flame Dragon Domain, which is very tolerant!"
Cao Ya whispered, but this had little impact. Any major road has countless branches, corresponding to too many directions.
"Is this the ancient domain?"
Cao Ya felt that from the moment he appeared, an invisible force enveloped him.
The source of this power is impossible to ascertain; all that is known is that it originates from the depths of the ancient domain!
The Ancient Domain is the core of the entire alien universe, and deep within it lies the origin of the alien universe!
It is full of both danger and opportunity. Countless cultivators, including those at the World Realm, Dao Lord, and even Emperor, have died here. But there are also many lucky ones who have obtained great fortune here and ascended to the heavens in one step!
The most obvious example is the Lord of the Destruction God Court back then. He was not yet a ruler, but only a slightly more powerful emperor. Yet he risked entering the ancient domain and ventured into the land of origin. He gained good fortune, greatly increased his strength, and refined the origin, becoming the Lord of another universe!
From then on, the Divine Court of Destruction was established, unifying the alien universe. Many emperors joined the Divine Court, serving as star lords or second-level divine generals.
With the example of the Lord of the Destroyer of the Divine Court, more and more cultivators began to explore the ancient domains!
But frankly, very few people actually gain anything from it.
"Now that we've come to another universe and are directly descending into the ancient domain, we should seize this opportunity and not waste it."
Cao Ya muttered to himself, "The dangers of the Ancient Domain are generally aimed at Dao Lords and those below them. Only by obtaining the core of the Ancient Domain—the Land of Origin—can there be more crises, and even the fall of an Emperor!"
Although Cao Ya is only a second-step Dao Lord, his combat power is enough to kill a top-tier Emperor!
"A Dao-Merging Treasure..." Cao Ya gazed at the ancient domain, his eyes revealing anticipation.
As the core of an alien universe, it is quite normal for it to nurture Dao-harmonizing treasures.
Even if it's not something too rare, Cao Ya will take any unusual item that can increase the success rate of achieving Dao Integration!
"If the ancient domain doesn't have it, then the origin land deep within it must have also given birth to a Dao-merging treasure!"
Cao Ya focused his mind and sensed that the core of the ancient domain was emanating an endless aura of the Great Dao, its location clear even without a map.
With a "whoosh," Cao Ya tore through space with one arm, traversing the void to reach the place of origin, and spreading his divine sense to scan the surrounding world for any treasures that caught his eye.
The ancient domain is extremely vast; a small territory like the Bright Light Domain would be insignificant within it.
Naturally, within the ancient domain, the Great Dao flows and various interfaces are born, just like the chaotic world in the normal territory, which also nurtures life and develops various civilizations.
Cao Ya did not rely on flying; no matter how fast he was, in the ancient domain, he was like a tortoise crawling.
It should be noted that if any two territories were to be traversed by air without relying on space travel, it would conservatively take hundreds of millions of years to do so!
Although a chaotic epoch is very long, it is measured in "trillions of years", generally around ten trillion years, and sometimes several trillion years.
Even if a Dao Lord doesn't perish halfway through his journey, he will still have a lifespan of 108,000 Chaos Eras.
However, spending too much time on the road is still uncomfortable and can easily lead to mental health issues.
"In fact, powerful masters all have means of transportation, such as flying boats inscribed with spacetime runes. But those things are ridiculously expensive. In the past, I had no need for them and was unwilling to spend the money. Now, I have to rely on myself to tear through the void to travel."
Cao Ya looked around and realized that he had passed through many worlds, some large and some small, some over a trillion miles long and some only a few hundred billion miles long. Among them, there were all kinds of civilizations, and within each world, there were also immortals and gods who had transcended the mortal world and could achieve longevity, which was a lifespan of 108,000 Chaos Eras!
To transcend 108,000 Chaos Eras, one must succeed in merging with the Dao and become an Eternal Emperor!
However, this place is only the outer edge of the ancient domain, not yet the core origin land. Although there are quite a few celestial gods, celestial immortals, true gods, true immortals, ancestral gods, and ancestral immortals, and occasionally a few world gods and chaos immortals can appear, Cao Ya has not yet discovered any Dao Lords.
As for Dao-Merging Treasures... Cao Ya didn't see a single one!
"Even if there are treasures on the outskirts, they are of little use to me now, even if they could help a Dao Lord's cultivation!"
"All I need are rare and wondrous items that align with the Dao!"
Cao Ya sighed softly and increased his speed. With each tear through the void, the distance he traversed became increasingly vast.
During this process, Cao Ya also encountered some dangers within the ancient domain.
It was like a spatial storm, rumbling and shattering the void. It was like a sharp blade that could cut through the divine body of a world god. Even a Dao Lord could not be careless, as there would be danger.
However, Cao Ya mobilized a portion of his magical power, reaching only the level of an ordinary emperor, and easily destroyed the vast spatial storm, thus passing through it.
In a nearby vast world, a Chaos Immortal was on high alert, fearing that his home world had been ravaged by a spatial storm, resulting in heavy casualties and the survival of almost all living beings.
The spatial storm suddenly disappeared, followed by a figure flashing by, leaving the Chaos Immortal dumbfounded.
"Who is that? The legendary Dao Lord?"
Cao Ya casually eliminated the natural disaster blocking his path, thus averting a great calamity for the world around him.
Decades later, Cao Ya was still in the ancient region, unable to reach the place of origin.
However, when he passed through a dangerous environment where spacetime was chaotic, natural disasters were frequent, and there was no life, even Dao Lords would turn pale at the mention of it, he sensed a deep evil intention!
"Hmm?" Cao Ya raised an eyebrow, not in a hurry to fly away, but lingered.
"Heh, where did this Dao Lord come from, so arrogant? He sensed the presence of me, the Three Silkworm Emperor, yet he remained unmoved!"
A chilling voice echoed, followed by a mournful cry from that space-time. A transparent drop of water, seemingly weighed down by time itself, slowly floated out.
Within the water droplet, light and shadow flickered, and a figure stepped out—a sinister-looking youth with nine malignant tumors on his forehead, each containing venom that swayed faintly.
The Three Silkworm Emperor stared at Cao Ya and realized that he was indeed just a second-step Dao Lord, someone he had never seen before. Clearly, he was not a prodigy from another universe, nor a disciple or descendant of some powerful figure.
Immediately, the Three Silkworm Emperor sneered and said, "You're unlucky to have met me!"
"So you are the Three Silkworm Emperor?" Cao Ya laughed as well.
