"Boom..."

Cao Ya, along with Hei Huang, Duan De, Hua Hua, and Jiu Liu San, left the dangerous place in the mortal realm and arrived at the Soul Light Cave.

This place has long been a forbidden zone, a gathering place for powerful cultivators. Even those at the peak of the Human Path or the Primordial Chaos Realm must give way and not be allowed to approach!

Attacking the Soul River is unnecessary unless you reach the True Immortal Realm; you're not even qualified to be cannon fodder!

"This is... the legendary Dog Emperor? A powerful figure who followed the Three Heavenly Emperors..."

When the heroes of the mortal realm saw the Black Emperor, they were first taken aback, then greatly alarmed, and then overjoyed.

This is the Dog Emperor who once followed the Heavenly Emperor, and is naturally an unparalleled imperial powerhouse, whose might shook the ancient history!

The Black Emperor glanced at Duan De and Jiu Liu San with a smug look. The two were speechless. In fact, their deeds were clearly much older, so why did so few people know about them or hold them in awe?

"Cao Ya, although you are powerful, you are still lacking compared to these seniors." Many cultivators said with smiles on their faces, seemingly happy to see Cao Ya suffer a setback.

Cao Ya rolled his eyes, knowing that his unparalleled record of sweeping through the Yu Jiu Realm made them wary.

After all, Cao Ya is a contemporary figure, and even younger than them, unlike Hei Huang, Duan De, Jiu Liu San, and Hua Hua, whose most recent contemporaries were from several eras ago, yet they have not had much conflict.

Those places with such conflicts, such as Silent Ridge, Star Feather Heaven, Four Tribulations Sparrow, and Chaos Abyss, will not come here to participate in the attack on the Soul River!

In addition, there are also a group of powerful cultivators, the three overlords, etc., who did not join the team. For some reason, they stayed in the mortal world to guard against the instigation of strange spies and traitors in the mortal world, who would take advantage of the absence of the heroes to launch an attack!

Regardless of past grievances, when faced with something strange, they temporarily set aside their old grudges and united against a common enemy!

After all, if the strange resurgence invades all realms, no one can escape it. That is the kind of annihilation that will be carried out from the root, with no chance of survival whatsoever!

Even if there are casualties in the conflicts between the two sides, they will not completely break off relations and fight to the death. Instead, based on their own development, in each era, it is either that one side is stronger and the other side is weaker, and they occupy more resources, or one side is stronger and the other side is weaker, and they reverse the situation.

In short, they will not go so far as to wipe them out completely, but leave a way out in case of unforeseen circumstances, so as to avoid a major disaster when the country declines in the future.

No one can guarantee that their family's heritage will last for generations and never decline.

The ancient Heavenly Court collapsed several times, let alone other clans and sects.

963 stayed at the First Mountain, rarely interfering with the outside world or plundering resources. Black Emperor, Duan De, and Hua Hua were even less likely to appear. Few people had ever met them before, let alone fought for territory.

As prehistoric elders, the weariness and sense of vicissitude emanating from these individuals were evident to everyone.

Even if they are completely outmatched, there is no need to worry that they will take matters into their own hands, sweep across the mortal realm, and compete with all parties for geographical resources such as mountains, rivers, and lakes, as well as cultivation resources such as pollen and exotic soil.

Without competition, the heroes naturally became quite respectful, showing great deference to their seniors and behaving with impeccable manners.

Furthermore, the contributions of our predecessors are beyond doubt and will be remembered in history!

Since the heroes are willing to attack the Soul River, this undoubtedly demonstrates their exceptionally firm stance: a fight to the death against the strange race! There is absolutely no possibility of surrender!

Naturally, they will respect the older generation of powerful figures who have made contributions!

But Cao Ya is different. So far, he hasn't made any major contributions—except for purging that group of undercover agents and traitors!

Furthermore, Cao Ya is a hero of this world. What if he develops the idea of ​​establishing his own sect, or even wants to unify the mortal realm and compete for the position of the Heavenly Emperor in order to seek great fortune for the mortal realm...?

Isn't this their competitor? It should be noted that many forces have already placed their bets and supported one of the three overlords.

Hundreds of thousands of years ago, many junior members of the great cultivator clans or sects were defeated by Cao Ya, which dampened their spirits and led to less than ideal progress in their subsequent cultivation, causing dissatisfaction among the great cultivators.

However, given Cao Ya's strength, they would not act rashly, only trying to gain some advantage verbally.

Moreover, since everyone had gathered at the Soul Light Cave, they ultimately shared the same stance. They would keep their verbal exchanges to themselves and avoid direct insults or physical altercations.

Their power must be reserved for the monstrous scum to savor!

"Senior." At this moment, experts from the Six-Eared Macaque clan stepped forward. There were Immortal Kings and True Immortals. They were very respectful and bowed to Black Emperor, Duan De, and Hua Hua. They also showed great respect to Jiu Liu San.

At the same time, experts from major clans such as the Daoist, Buddhist, Asian Immortal, Zhou, Ji, and Silkworm Valley also showed them respect.

Black Emperor, Duan De, and Hua Hua were all deeply moved. These forces, tracing their origins, all had some connection with the heroes of the ancient times, whether close or distant; they were either successors of the Daoist lineage or descendants of the same bloodline.

Unfortunately, those people from back then can no longer see them; many eras have passed.

"We must not be careless on our journey to the River of Souls! Even with so many of us united, we must proceed with extreme caution."

"Nine Six Three warned, looking around with considerable confidence. Those who have arrived at the Soul Light Cave include not only various Great Universes and Ultimates from the Heavenly Emperor Era spanning nearly ten million years, but also Universe Ultimates, prehistoric True Immortals, and even Immortal Kings, all of whom have been revived and appeared here to participate in the battle to attack the Soul River!"

This force is already extremely powerful; sweeping across the mortal realm and intimidating all worlds is nothing more than a trivial matter.

"In the ancient times of immortals, whether it was the Nine Heavens and Ten Earths, or the Immortal Realm and the Other Realm, none of them could compare to the mortal world we are in now!" Jiu Liu Da laughed. Although he was born in the chaotic ancient era, as a soldier of the Heavenly Court, he had dealt with the Immortal Realm and the Other Realm.

Those two ancient realms, though home to many kings, could not escape the present mortal world.

Furthermore, Black Emperor, Duan De, Hua Hua, and himself are all outstanding individuals in the Immortal King realm, at the very least supreme giants, or even Emperor Light Immortal Kings. Among the others, there are also ordinary Immortal Kings, top-tier Immortal Kings, and Immortal King giants! As for the remaining True Immortals, there is no need to say more.

In comparison, the Immortal Realm and the Otherworld at their peak were indeed inferior to the Mortal Realm.

This is quite normal. The Heavenly Emperor Calendar alone in the mortal realm spans over nine million years, and before that, there were various eras, accumulating to over a hundred million years!

Besides, there were survivors from the great repairs of previous eras, such as Taiyi, including Jiu Liusan, Heihuang, and Duan De, who were also prehistoric powerhouses, not people from this era.

The ancestors of the Six-Eared Macaque clan, such as the Fighting Macaque King, or the king-level ancestors of major forces like the Daoist, Buddhist, and Asian Immortal clans, none of them have lived for at least two or three eras in this world!

Accumulated over countless eras, how could the foundation of the mortal realm be meager? It is incredibly profound, beyond imagination!

If the assembled team isn't strong, then they wouldn't dare to venture into the River of Souls.

This large group of people, undoubtedly led by Jiu Liu San, Hei Huang, and Duan De, not only had the highest cultivation and strongest strength, but were also the most senior and knew the most secrets.

Cao Yacai is comparable to an ordinary Immortal King, at most able to exchange blows with a top-tier Immortal King. If facing a giant, he is no match at all. In such a great battle, his strength is far from enough to establish a banner; he is merely a capable member of the team!

Of course, Cao Ya is no less impressive. Among these hundred or so great cultivators, there is no doubt that most of them are at the True Immortal Realm, with a considerable number at the Great Universe, Ultimate, and Universe Ultimate levels. However, those who have truly broken through to become kings and reached the Immortal King Realm are still rare!

Furthermore, most of these kings are ordinary immortal kings or top immortal kings. There are only a few giants, and the only ones at the level of supreme giants or Emperor Light Immortal Kings are Jiu Liu San, Black Emperor, Duan De, and Hua Hua.

Therefore, if ranked by combat strength, Cao Ya would definitely not be in the top five, but he would hover around the top ten.

"Boom..."

Deep within the Soul Light Cave, a hundred or so experts from the mortal realm unleashed their power, shaking the world and disrupting the outer galaxies. Hundreds of millions of living beings were filled with fear and awe!

At this moment, forbidden zones such as Chaos Abyss, Silent Ridge, and Star Feather Heaven are all lying in wait, not daring to make the slightest move. Otherwise, if the heroes join forces and come, they will easily flatten any forbidden zone!

However, there are quite a few powerful forces with ulterior motives. When they unite, they become a force to be reckoned with. In addition, there are many spies who act without evidence or even when they are unaware of the danger. Their actions can easily cause panic and make the evolved beings feel insecure. Before the strange invasion even begins, the mortal realm will be torn apart. It is very likely that the sky will collapse and the earth will sink during the great battle, ending the apocalypse!

Therefore, the heroes did not cleanse the mortal realm, but waited. As long as a new Heavenly Emperor was born, surpassing the Immortal King realm, and attaining supreme status and unparalleled divine power, it would be enough to purify the mortal realm and build the strongest alliance against darkness! There would be no major upheaval!

Furthermore, they were going to charge into the Soul River. Although their numbers exceeded one hundred, they still felt it wasn't enough. Naturally, they didn't want any losses to occur prematurely, which would damage morale and weaken their fighting spirit.

"good!"

Seeing the heroes full of vigor, even the ancient monsters from prehistoric times, who had lived for more than one era, were still unusually calm and no longer showed signs of vicissitudes. Instead, they were full of fighting spirit. Jiu Liu San, Hei Huang, and Duan De exchanged glances and felt quite gratified.

Even though there are traitors who have abandoned their hometowns, there are still many who hold fast to their principles and are determined to stand against darkness.

No matter the era, there is never a shortage of virtuous and ambitious people who emerge in the world and leave their names in history!

"Let's go!" Black Emperor shouted, his fur flying. Without hesitation, he took the lead, carrying the Emperor's corpse on his back and the broken bell in his hand. He kicked open the gate and was the first to enter the Soul River territory!

Duan De, Hua Hua, and Jiu Liu San followed closely behind, while Cao Ya, the Fighting Macaque King, the Buddha Clan Old King, the Silkworm Valley Old King, the Dao Clan Old King, and other king-level combatants all stepped into the Soul River. Finally, there was a group of true immortals!

"Damn it, I'm the most powerful True Immortal in the Ultimate Realm, and I can't even make it into the top ten here, let alone the top twenty..." Li Da muttered.

"Be content!" Tai Yi sneered. He was more ancient than Li Da, not only an ancient person before the Heavenly Emperor Era, but also a survivor of the previous era. However, whether he could even make it into the top thirty was another matter! Although he was a Yu Jiu, he was not as fierce as Li Da.

"The more experts the better! That way we can reap greater rewards. Ideally, we should take away a batch of corpses of powerful cultivators from the Dark Realm for us to study, dissect their secrets, test various ideas, and keep records."

The master of the Black Blood Research Institute was indifferent; he only hoped to return alive and carry the Dark True Immortal on his back... If it were the corpse of the Dark Immortal King, that would be even better!

If he could truly dissect the remains of a Celestial King, the master of the Black Blood Research Institute felt that he would have a great chance of breaking through to become a King!

"You bunch of little brats, be careful and don't be careless. You haven't seen the cruelty and bloodshed of the Soul River yet!" Black Emperor turned around and shouted, reprimanding the group.

Li Da, Tai Yi, the master of the Black Blood Research Institute, and others all had strange expressions. In the mortal realm, they were all patriarchs, with at least tens of millions of years of history, yet in the Dog Emperor's mouth, they were called little guys...

Well, Black King's seniority is indeed many times higher than theirs!

Upon thinking of this, the heroes felt somewhat annoyed. How could a dog have become their senior?!

"Woof!" Black King barked, knowing from the expressions on their faces what they were thinking.

"Stop talking nonsense." Jiu Liu San said irritably. They've already entered the Soul River, yet they're still acting so recklessly.

"The River of Souls, a strange and wondrous realm, where souls from all the heavens have fallen, but the river endures forever." Cao Ya murmured. As far as the eye could see, the great river flowed slowly, its surface calm, yet everyone could sense the awe-inspiring divine power beneath its surface!

Here, even a Celestial King constantly feels threatened, as if pricked by thorns.

The arrival of the heroes seemed to disturb the River of Souls. Suddenly, the waves surged and the waters rose and fell. Then, a torrential downpour swept across the sky. But as soon as the raindrops rushed up from the River of Souls, they all turned into soul light, carrying chaotic energy, and rushed towards the powerful figures!

Most chillingly, those soul lights seemed to have taken human form, their figures densely packed, flowing with black blood, exuding a foul aura, disheveled, their faces covered in blood, their eyes empty, only emitting mournful roars and demonic sounds of the Great Dao, descending upon the crowd, capable of killing even immortal experts!

Fortunately, this is the River of Souls, so even if there is a clash of forces, it is difficult to affect the outside world.

Once everyone had entered the River of Souls, the portal immediately closed, severing the connection between the River of Souls and the mortal realm to prevent any unforeseen events.

"boom!

"In an instant, sand and stones flew, a strong wind arose, and torrential rain poured down on both sides of the Soul River. The scene was magnificent, with the power of life and death seemingly rotating. All the heavens appeared, and wails of agony continued."

However, such an astonishing scene was nothing special in the eyes of the heroes.

Those who reach the realm of immortality are not weak; whose hands have not been stained with blood?

If they wish, even more terrifying scenes could appear, and they might not even be illusions, but could very well be real scenes from the past!

"That's all the commotion? The River of Souls isn't that scary." Li Da curled his lips, finding the scene less terrifying than the bizarre entanglement he witnessed when he was tormented by the Four Extremes Floating Soil.

"So reckless! How did Number Four teach you back then?" 963 glanced at him sideways. The truly powerful one hadn't appeared yet!

Li Da chuckled. Although it was Number Four who had instructed him, the group was essentially one, and Li Da would not disobey his master's reprimand.

Taiyi and the others chuckled to themselves, secretly hoping that Li Da, that scoundrel, would suffer a setback!

“We have ventured this far, and even if the creatures of the Soul River have been dormant for countless ages, some must have already awakened,” Cao Ya said in a deep voice, fully alert, not letting any slightest movement escape his perception.

At the peak of the Soul River, there was an Immortal Emperor in charge. Even if the Immortal Emperor returned to the Calamity Plateau before the end of this era, there would definitely be a few Quasi-Immortal Emperor level experts left behind.

Even if such a great master is asleep deep in the River of Souls, he must possess all sorts of incredible power, enough to destroy the Great World!

Below this, those who routinely manage affairs in the Soul River are Emperor Light Immortal King, Supreme Giants, and others. With Jiu Liu San, Black Emperor, Duan De, and Hua Hua among them, it is not a problem.

"But we cannot be careless in the slightest." (Scan the QR code to download Hongxiu and Xiaoxiang's joint promotion: New users can read for free for a limited time.)
