"A dark cultivator at the Immortal King Realm!" Cao Ya focused his mind. That monster with golden scales, though humanoid in form, was definitely not human!

This monster had black blood flowing from its mouth, which was extremely polluting. Even ordinary immortals dared not provoke it, as they would easily fall into an ominous abyss.

However, Cao Ya possesses the combat power of a Celestial King, so he can confront him head-on!

The will of death and the will of reincarnation can protect one's safety and prevent contamination. Sword intent and knife intent, on the other hand, can cut away darkness and sweep away mystery!

"To be able to defy a Celestial King in the True Immortal Realm, kid, you're quite impressive!" the golden-scaled humanoid monster said indifferently, its gaze cold yet as captivating as a celestial blade!

As a Celestial King, this monster with golden scales has lived in the River of Souls for more than ten eras!

Throughout countless cycles of birth and death, he would go out each time to suppress and kill immortals from all realms, and to devour and consume a vast number of living beings, becoming their foundation.

Over the centuries, it is estimated that no fewer than hundreds of billions of lives have perished at the hands of this monster!

"However, I am not a fallen immortal king from all realms, but a true being of the Soul River. This is my home ground. If I cannot defeat you, a mere true immortal, I would be unworthy of being called an immortal king!" the golden-scaled monster said confidently, as an ominous substance spread and contaminated Cao Ya.

“Buzz…” The meaning of reincarnation flowed across Cao Ya’s body, annihilating the ominous matter.

"Heh, you do have some skill. No wonder you killed the Fallen Immortal King." The golden-scaled monster sneered, but didn't take it seriously. His power was far beyond what the Fallen Immortal King could match!

"Those traitors who betrayed their homeland for power are just expendable resources to you. They deserve it!"

Cao Ya muttered to himself, "Degenerate True Immortals and Immortal Kings, though they have undergone transformation and are filled with ominous intent, have never actually been accepted by the true beings of the Soul River. They are quite contemptuous of them and regarded as cannon fodder!"

Otherwise, why didn't any dark creatures appear to help that group of fallen cultivators who crawled out from the bottom of the Soul River?

Monsters like the white peacock, the ancient crow, and the golden-scaled monster remained behind the scenes, coldly watching them perish.

With the absence of this group of corrupt cultivators, the Soul River's energy also benefits from the competition among a group of experts, which is a good thing!

If it weren't for the fact that they wanted to lure all realms and corrupt the heavens, they themselves would have to take action to eliminate the corrupted cultivator, lest they tarnish the reputation of the strange!

In the eyes of the dark creatures, it is strange and powerful, having never failed throughout countless eras, reaping the harvest of countless civilizations, with profound accumulation and magnificent power. The number of supreme beings and unparalleled beings in the heavens is also numerous.

The myriad realms and heavens are like pastures; occasional changes won't cause any major upheavals.

Naturally, all the strange creatures have an arrogant attitude and look down on all the spirits in the heavens.

"Fallen cultivators are useless. They only have a little meaning when they are used as cannon fodder to consume your power." The humanoid monster with golden scales sneered. Those fallen immortals actually thought they had become creatures of the Soul River... It was utterly ridiculous!

The most powerful and mysterious true blood, even if it spills out a little power, is enough to corrupt all living beings. And watching the heroes of the heavens fall one after another and be tainted by ominous substances is also an interesting thing for many dark creatures. They are happy to see their former friends and relatives kill each other.

However, there are always some dark creatures who get bored. Instead of wasting time, why not take matters into their own hands, harvest a territory, and start feeding?

However, due to certain considerations, the higher-ups had given instructions to lure the powerful beings of the heavens, so these Immortal Kings could not openly oppose it.

They can do some underhanded things without anyone caring; they're a bunch of traitors, and the dark creatures look down on them.

Cao Ya didn't care about the death of the traitor; he had personally killed one before.

The creatures from the opposing realm are the most pressing enemy to be dealt with!

However, he was also somewhat worried about whether the immortals, working together, could push back the shadowy figures and the evil insects, and wipe out the dark army composed of countless mummified corpses of the Heavenly Venerable Realm and the Primordial Chaos Realm!

There are too many experts at the peak of the human realm, numbering in the tens of thousands. Even if a True Immortal is far superior, being besieged by hundreds of Heavenly Venerables and Primordial Chaos Realm experts at the same time, plus the shadowy figures and evil insects from the Immortal Realm, makes it hard to guarantee that no unexpected events will occur when charging head-on!

At this moment, Jiu Liu San, Duan De, Hei Huang, and Hua Hua, these four strongest experts, all have formidable enemies and are fighting desperately on the banks of the Soul River!

Meanwhile, many of the old kings were also fighting against the monsters of the king realm, and were even at a disadvantage, suffering numerous injuries!

There was simply no extra power to support the immortals; they had to rely on themselves to resist the endless enemy!

Cao Ya was a True Immortal at the peak of the Yu Jiu realm. Initially, he joined the other immortals in slaying the Calamity Insects!

Just now, he killed a dozen or so evil insects, greatly reducing the number of Dark True Immortals and lightening the burden on the immortals in the mortal realm!

"Cao Ya, focus on engaging the enemy. Don't worry, we won't lose on the battlefield below the King Realm!"

Li Da spoke, his hands waving, radiating brilliance, as he fought against the young white crow, suppressing it and causing it to cough up blood repeatedly.

Bai Ya's face was grim. He had thought that after receiving his father's teachings, he would be invincible in the True Immortal Realm and would be able to break through to become a King in this era in no time. Who would have thought that he would be no match for a Yang Realm Ultimate Realm expert!

"You won't be able to keep this up for long. On the battlefield of the King Realm, the mortal realm will surely be defeated!" Bai Ya said with a stern face.

Li Da laughed, "So what? I'll kill you before the Immortal Kings decide the victor!"

Before he finished speaking, Li Da launched a frenzied attack, his boundless killing intent surging like a vast ocean wave, extremely violent, forcefully suppressing Bai Ya, splashing black blood, ending one of his lives!

"I am immortal!" the white crow roared, its soul river energy surging, regrouping and reappearing.

Li Da frowned, finally understanding the helplessness of the heroes in the ancient book. Even if he was stronger and could kill dark creatures, he could not stop the spread of the strangeness. He was reborn one after another, and eventually he was exhausted to death!

"However, if I can kill you once, I can kill you a hundred times, a thousand times! I want to see how many times you can be resurrected!"

Li Da launched a fierce attack to slaughter the monster; this was his firm and unwavering resolve!

Besides Li Da, Tai Yi, the master of the Black Blood Research Institute, and the True Immortal Ancestors from various forces in the mortal realm all went all out to fight the black shadow and battle the evil insects. The aftershocks destroyed a large army, and the dried corpses were pulverized and turned into ashes. However, an ominous aura burst forth, empowering the dark creatures and increasing their combat power, making it difficult for the immortals to deal with. They had to avoid the ominous aura to avoid being contaminated.

As true immortals, they could indeed ignore and easily remove any trace of ominous substances.

Unfortunately, this place is the River of Souls, which is inherently dark and dense. With so many powerful immortals taking action, countless strange creatures at the peak of the human realm have died. When they converge, a massive amount of ominous matter surges up, which even true immortals have to avoid!

However, they did not put pressure on Cao Ya. Being able to kill more than ten calamity insects from the Immortal Realm had already reduced their burden.

"Haha, Cao Ya, don't underestimate us! A mere hundred or so True Immortals... Hehe, these scum, whether they are shadows or calamity insects, are no match for us! Even an army of tens of thousands of peak-level cultivators would be no match for us!" Tai Yi laughed.

With a whoosh, Taiyi's entire body burst forth with a dazzling rain of light, yet it also exuded a demonic Daoist aura, a deep bloody scent, and immense destructive power, engulfing Taiyi and sweeping across the Soul River army!

"If I could obtain the body of a Soul River Immortal... as long as I take it back for research, analyze it with various instruments, and collect data, I would have a great chance to break through to become a King!"

The master of the Black Blood Research Institute spoke, his eyes burning with fervor, showing no fear whatsoever, but rather a high fighting spirit!

"Everyone, it's time to unleash our full power! If we hold back any longer, we'll all be finished here!"

"If you die in the outside world, there is still a chance for your soul to leave and be reincarnated. But if you perish in the River of Souls... ha, your soul will be devoured by the monsters here, and there will be no hope of survival whatsoever!"

Over a hundred True Immortals from major mortal forces such as the Buddhist Clan, Taoist Clan, Heng Clan, Ji Clan, Sub-Immortal Clan, and Silkworm Valley, all brimming with heroic spirit, their bodies stained with blood, some representing their own people and others their enemies.

Even if one is old and frail, this kind of battle still ignites passion!

"Boom!"

!

Immediately following, the immortals roared, and the Daoist magic, Buddhist light, and immortal radiance surged forth, stirring up the void and disrupting the Great Dao and divine laws. It seemed to possess unparalleled power, capable of destroying the world and suppressing the universe!

"Buzz..." Taiyi, the master of the Black Blood Research Institute, and others displayed a power completely different from that of the True Immortals of the major powers. A phantom passage suddenly appeared behind them. At the end, an ancient figure sat cross-legged, its face indistinct and very vague. It was unknown whether it was their past life or the remains of some other terrifying creature.

That ancient phantom, with its profound Daoist aura and unparalleled power, transmitted wisps of energy that seeped into the bodies of Taiyi, the master of the Black Blood Research Institute, and others, empowering them and making them incredibly ferocious!

In an instant, Taiyi and the others' combat power increased dramatically, becoming completely comparable to a normal invincible being in the Ultimate Realm!

"kill!

"They roared and lunged forward, swinging their fists and displaying incredible magical power, smashing through the army, killing the evil insects, and scattering the black shadows, yet they were extremely fierce!"

"These guys are really strange! They survived the cataclysmic destruction of an era; they must have some other trump cards up their sleeves!"

When the powerful immortals were waging war, they noticed the hidden plans of these few overlords of the underworld. Their eyes flickered slightly, but they didn't look surprised. Instead, they showed a hint of curiosity.

"There are rumors in the mortal realm that the overlords who can keep the underworld in check are all extraordinary figures with unfathomable powerful beings behind them... Now it seems that the rumors are true!"

The immortals marveled that in such a vast world as the mortal realm, none of those who broke through to immortality and established their own power, which has endured for countless ages and whose lineage has never been broken, were weak. Their opportunities were so great that outsiders could hardly imagine them!

It is no easy task to cross the pinnacle of humanity and attain immortality, let alone to overcome the calamity of destruction and continue the lineage. This is even more difficult and dangerous, and only the strongest can accomplish it!

Of course, the backgrounds of these immortals are no weaker than those of the underground overlords!

Clans such as Heng, Fo, Dao, Ji, Zhou, Yaxian, and Cansang Valley currently have elderly Immortal Kings presiding over them. Tracing back to the past, almost all of them have connections with Quasi-Immortal Emperors, and even Immortal Emperors are not entirely unrelated.

To have dominated the mortal realm for centuries, how could it be possible without some foundation and sufficient strength?!

So they didn't think too much about it. After observing for a while, they focused all their attention on fighting alongside the Soul River army in a bloody battle!

"Those who dare to invade the River of Souls shall be executed!" Dozens of dark figures roared, uttering beast-like sounds. Because they contained the power of the Great Dao, anyone could understand them without any language barrier.

These dark figures, of unknown race, were bound by chains forged from immortal metal, making them extremely hard. In battles within the realm of immortals, they proved highly effective, causing surging soul light and the dark rules to pulsate!

The immortals retaliated, each wielding their forbidden magical artifacts—treasures refined over countless years, imbued with magical power—and unleashed them on the spot. However, these artifacts collided with the chains, sending sparks flying and capable of obliterating time and space and crushing the world!

"Hiss!"

!

The remaining calamity insects scurried forward, devouring fragments of the Great Dao, consuming nothing in their path!

This kind of calamity insect, which can destroy the world after reaching its peak and complete form, has excellent evolutionary potential and its digestive ability is also remarkable!

However, Taiyi, the master of the Black Blood Research Institute, and others received the power of the mysterious figure and descended into the arena. Its essence was far beyond the True Immortal Realm. It forcefully burst the Evil Insect, causing it to shatter into pieces and emit a miserable howl, unable to break out of its cocoon and become a butterfly!

"charge!

"That vast army, composed of Celestial Venerables or Primordial Chaos Realm experts, was quite powerful, but here they were just cannon fodder."

Their charge was easily blocked by the immortals, who casually retaliated, shattering hundreds of dried corpses. Their bodies collapsed and their souls were annihilated, leaving only a dense, ominous substance that seeped out and permeated the entire river!

Compared to the attack of the Soul River army, the ominous substances left behind by the dead were more feared by the immortals, who were unwilling to get involved with them!

After all, this is the River of Souls, which is inherently dark and shrouded in mystery. With so many strange creatures dead here, and ominous substances piled up, even Immortal Kings, let alone True Immortals, would turn pale at the mere mention of it!

"Ha, you are destined to fall, there is no escaping it. Darkness is the final destination for all living beings!" the golden-scaled monster sneered, black blood gushing from the corner of its mouth, twisting and terrifying.

"There are indeed many ominous substances here, but the only saving grace is that they are not the most powerful and bizarre true blood. They are merely multiple transformations after being tainted by it. Although they are highly polluting, we can still deal with them!"

Cao Ya thought to himself, the strongest true blood is not much even among the strange races. Except for dealing with the supreme beings of the heavens, how could he use it lightly?

For example, the Corpse Immortal Emperor in [Perfect World] was corrupted by true blood when he was proving the Dao, which led to his fall. His corrupted body gave rise to a new soul, which was cruel, crazy and extremely bloodthirsty!

At the same time, he glanced at them and couldn't help but laugh. Indeed, they were all true immortals, so why should he worry about them?

In terms of background, almost every one of those hundreds of True Immortals had a more impressive background than him!

Cao Ya has neither a King Realm Ancestor nor a mysterious creature to connect with.

"I'll rely on myself!" Cao Ya chuckled. No matter what universe or world it is, it's still Cao Ya!

"A genius from the mortal realm, capable of defying a Celestial King in the True Immortal Realm... Cao Ya, your flesh and soul must be incredibly delicious! I can't wait to taste you and devour you raw!"

The golden monster licked its lips, its appetite greatly stimulated, and at the same time, a chilling killing intent enveloped Cao Ya, pressing him forward!

Looking at the monster's twisted form, which was humanoid and reeked of decay and stench, Cao Ya immediately blocked his sense of smell to avoid feeling nauseous.

"She's too ugly!" Cao Ya pouted.

The golden monster's face darkened, its gaze turned cold and menacing, and its aura as a Celestial King swept across the sky!
