The Old Man of Annihilation suddenly realized something. He had been wondering where the World Dao Ancestor, a newly promoted Quasi-Immortal Emperor, got the confidence to single-handedly block him and the Hong Emperor. Now he understood!

"Those two immortal worlds are dragging our souls down and scattering our power... Well, as usual, you should be able to stop me and Emperor Hong!"

The Old Man of Destruction saw that the Niwan Palace world, which he had blasted into darkness, quickly revived.

However, there was still no trace of panic on the face of the Old Man Who Destroys the World.

"Even so, he is doomed!" Emperor Hong erupted, his purple aura surging, stretching across three thousand realms and spanning billions of miles!

As an ancient quasi-immortal emperor, he was proficient in countless Daoist arts.

Although there aren't many things to show for it at this level, there are still more than a handful.

The technique that Hongdi believed could be effective in battles between quasi-immortal emperors... without a doubt, it was a top-tier divine power throughout history! Unless the ten fierce treasure techniques were combined, it would be difficult to withstand any one of them individually!

Furthermore, the Hong Emperor continued chanting curses, invoking the strange Dao of the universe, causing black mist to sweep across the land.

Cao Ya felt a chill run down his spine, as if he were being watched by some monstrous beast.

"Boom!" Cao Ya used all the ultimate techniques of the seven-star Immortal Kings in the [Eternal Life] universe, such as the "Primordial Heavenly Dao", "Thirty-Three Heavens Creation Divine Fist", and "Origin Divine Fist", without holding back, causing various colored air currents to intertwine in the sky and cover the firmament.

That curse-like power and dark energy were finally suppressed and collapsed.

However, Hongdi's ability to fight head-on is by no means weak!

"Bang!" The purple-gold palm force swept across the north and south, cleansing the east and west, shattering all the laws of nature, and ceasing to exist.

The Emperor's body exuded an air of unparalleled nobility, inspiring awe and a sense of surrender, even to the point of sacrificing one's life.

Of course, Cao Ya activated the "Smile While Picking Flowers" technique, remained steadfast in his principles, and no psychological manipulation could work.

Instead, the artistic conception of picking flowers spread out, causing Emperor Hong to be slightly dazed.

"Clang!" The purple-gold crown on his head trembled suddenly, awakening the Hong Emperor's intelligence.

Immediately, Emperor Hong became stern, his gaze towards Cao Ya filled with apprehension.

"I almost fell for your trick!" Hong Di said coldly. "But I am a veteran Quasi-Immortal Emperor. Even though you destroyed both of my Emperor Artifacts, I still have this Emperor Crown to protect my mind!"

The purple-gold crown swayed, casting down countless strands of divine light, exuding an aura of nobility.

However, Emperor Hong was still very hesitant and did not rush to make a move.

The clash just now made Hongdi realize that this World Dao Ancestor's power was unfathomable!

If you underestimate someone just because they are a newly crowned emperor, the final outcome will likely not be good.

"Senior, let's work together! If we join forces, we can surely kill the World Dao Ancestor!"

"At that time, his blood, muscles, bones, soul, energy, and origin will all be ours to possess. Whether we devour them or refine them into treasures, they will be rare treasures that are hard to find in the Boundary Sea!"

Emperor Hong spoke, not wanting to face the World Ancestor alone.

Most importantly, the ultimate skills and divine techniques of the World Dao Ancestor are unexpected and unpredictable.

Some of the profound mysteries of these methods even astounded the Hong Emperor.

Could it be that the World Dao Ancestor's current realm and rapid advancement were due to obtaining the Immortal Emperor's inheritance?

Even Emperor Hong couldn't help but ponder this; there was no other explanation.

He knew of the existence of the Corpse Immortal Emperor, whose death for unknown reasons proved one thing—that Immortal Emperors had been born in the prehistoric era of the Boundary Sea! There might even have been more than one!

Such a powerful figure may have foreseen the past and future, and left behind a legacy; who knows?

It was the work of a Celestial Emperor, and even a Quasi-Celestial Emperor couldn't see through it; it could only be left to those with the right destiny.

Considering the situation of the World Dao Ancestor, Emperor Hong felt that his guess was probably correct.

In fact, not to mention Emperor Hong, even the Old Man of Annihilation couldn't help but have wild thoughts.

"It seems that your destiny has exceeded our expectations."

Because the World Dao Ancestor and others did not accept the invitation, the Old Man of Annihilation's expression changed from a gentle spring breeze to a cold and ruthless winter wind.

"Smack." The Old Man of Annihilation struck with his palm, plunging everything into darkness, so dark that even the Path of Light could not be lit.

Cao Ya solemnly declared that the power of the World Destroyer Elder was beyond question; he was a supreme quasi-Immortal Emperor!

"Buzz..." The Void Realm and the Niwan Palace World are influencing the Old Man of Annihilation.

Cao Ya used most of his laws and rules to fight against the Old Man Who Destroys the World.

For example, the Path of Wind and the Path of Fire in the [Snow Eagle Lord] universe, the Great Sun Tathagata Fist in the [Sacred Ruins] universe, the Path of Light in the [Desolate Era] universe, and the Path of Reincarnation in [Supreme Being]...

It's no exaggeration to say that Cao Ya spent at least 70% of his combat power battling the World Destroyer!

Even so, Cao Ya still couldn't gain the upper hand, managing only a draw.

It should be noted that, in summary, Cao Ya is at the peak of the six-star level, infinitely close to the seven-star level!

With 70-80% of his magical power, he's practically at the upper end of the six-star peak level.

If we also consider the entanglements between the two worlds... the actions of the Old Man Who Destroys the World are simply terrifying beyond measure!

The title of "First Emperor Who Created Heaven and Earth" held by the Old Man of Annihilation is somewhat exaggerated due to the existence of the Corpse Immortal Emperor, but overall, it is still well-deserved, as his cultivation is extremely profound.

Even though Cao Ya already knew the details of the World Destroyer, he was still amazed when he personally fought him!

Only by actually fighting and battling with him can one realize the power of a Quasi-Immortal Emperor, which far exceeds one's imagination!

However, compared to Cao Ya, the World Destroyer and the Hong Emperor were even more shocked!

"So many divine laws... No wonder he is the World Ancestor, an existence capable of creating worlds large and small!"

The old man who was about to destroy the world spoke in a low voice, his words filled with emotion.

He broke through to the Quasi-Immortal Emperor level in prehistoric times. In order to seek the true meaning of the Emperor Realm, he deliberately fell into darkness, guided the black mist, and cleansed his body and soul, which can be said to have fundamentally changed him.

Unfortunately, his attempt to become an Immortal Emperor still ended in failure.

However, after countless years of cultivation, the Old Man of Annihilation's cultivation level had long since approached the Immortal Emperor realm, and his combat ability was even more outstanding among those of the same level!

The restraint between the two worlds was indeed effective, but the problem was that the Old Man of Annihilation also had the help of the Hong Emperor.

In the end, he still failed to achieve his goal; his fierce palm strikes were all blocked by the World Dao Ancestor...

It has to be said that the strength of the World Dao Ancestor has reached the pinnacle of Quasi-Immortal Emperor!

Now, both the Old Man of Annihilation and Emperor Hong felt that their previous conjectures were now certain.

The world's Dao Ancestor must possess the secret techniques of an Immortal Emperor!

A fiery glint flashed in the eyes of the Old Man of Annihilation. If he were to obtain the divine power of the Immortal Emperor… with his foundation, he had already touched upon the Emperor Realm; even the slightest touch would guarantee a 100% advancement!

Even the unknown mystery, due to his formidable combat strength, could not stop him from breaking through to the next realm!

If the Old Man of Destruction is so greedy, how good can the situation be for the Emperor Hong?

"Kill!" Hongdi roared, and the purple-gold crown dripped with rosy light, obscuring Hongdi's face, making his true appearance impossible to see, and also severing his true spirit from the interference of external energy.

At the same time, with a loud bang, it was as if the sky had shattered and the chaotic energy was released all at once. The chaotic mist rose up and was stirred by Hongdi, forming a great handprint that was powerful enough to capture gods and destroy immortals!

This is a forbidden chapter in the Hongdi Scripture, where chaos is created and unleashes unparalleled power!

As expected, this devastating technique pierced through the energy of the World Dao Ancestor.

"As expected of a Quasi-Immortal Emperor who cultivated independently, he is indeed very strong!" Cao Ya even had the leisure to exclaim in admiration.

Upon hearing this, Emperor Hong's heart sank, and he coldly snorted, "Even when death is imminent, you still pretend to be a god!"

He also caught a glimpse of the World Destroyer's movements and unleashed his own ultimate move, launching a fierce attack!

Immediately, Emperor Hong felt relieved. He didn't believe that this World Dao Ancestor could withstand the combined attack of himself and the Old Man of Annihilation! Even if he didn't die, he would be crippled!

Putting myself in his shoes, I know he definitely wouldn't survive!

Even if there were another World Destroyer, he would still be severely injured!

"Fortunately, I am patient and steady, and only now have I been able to break into the end of the Boundary Sea."

Seeing this, Cao Ya felt secretly fortunate. If he had arrived in the Dark Land with the combat power of a six-star peak, comparable to a quasi-Immortal Emperor... his fate would have been sealed, and he would have died!

"Now I possess multiple extraordinary systems and have mastered countless principles."

"Flame, lightning, wind, water, light, darkness, time, space, cause and effect, fate, destruction, death, life, sword, knife, body tempering... it covers almost every aspect of a cultivator's life!"

"Thanks to me from all the great universes like [Peerless Sovereign], [Desolate Era], [Stellar Transformation], [Sacred Ruins], [Eternal Life], [Immortal Gourd], [Snow Eagle Lord], [Primordial Era], and so on!"

Cao Ya's physical body, with multiple layers of body-refining cultivation, is already immortal and indestructible, reaching the realm of "heaven and earth decay, but I am immortal." He can withstand even the killing move of a peak six-star cultivator.

Similarly, his soul was also ridiculously strong; even the Emperor's Sword could hardly injure him!

It should be noted that he, from universes such as [Eternal Life], [Snow Eagle Lord], [Immortal Gourd], [Stellar Transformation], and [Longevity Realm], was already at the peak of the six-star level!

The remaining universes also have quite a few six-star elementary, middle and advanced levels.

As a result, Cao Ya's defense and vitality far surpass those of his peers.

As the progenitor of the Nine Nether Hounds, the Old Man of Annihilation was physically strong and incomparable to others of the same level, but when compared with Cao Ya, he was still slightly inferior.

Naturally, Cao Ya's body was surrounded by nine-colored rays of light, and then he rushed out!

"Sizzle." The Hong Emperor's great handprint was forcefully shattered by Cao Ya!

The chaotic energy flow could not stop Cao Ya in an instant; it was all crushed!

The black aura emitted by the Old Man of Annihilation was forcibly pierced through by Cao Ya and could not be sustained!

At this moment, Cao Ya is like a god who created the world, or a demon who destroys the world, looking down on time and space!

Even the might of the Annihilation Elder and the Hong Emperor paled in comparison to him.

"Damn it!" Hong Di exclaimed in shock and anger. Just how strong was the Dao Ancestor of this world?

"Haha, very good! This is a worthy opponent!" The Old Man of Annihilation laughed loudly instead.

His eyes scrutinized Cao Ya, and he murmured:

"If I eat you, I'll be able to break through to the next realm again, and I won't have to fear any misfortune!"

Thinking of the Celestial Emperor's majesty, the Old Man of Annihilation was unusually excited.

With a whoosh, the World-Destroying Elder revealed his true form. He was no longer a withered old man, but a world-shaking super divine beast—the Nine Nether Hound!

This beast has nine heads, is extremely ferocious, and even has bull horns on its head that can pierce the sky!

"Boom!" The true form of the World Destroyer Elder, with one of its heads, used its bull horns to stab at Cao Ya.

It seemed like an indestructible imperial spear, its bull horns indestructible, causing even the laws and rules to tremble.

Cao Ya's eyes narrowed slightly. He could sense that even an immortal physique would be injured under the attack of such a ferocious bull horn!

"Buzz..." At the same time, several of the old man's heads were also tearing at Cao Ya.

"Thump!" Cao Ya suddenly pointed his finger, and the Niwan Palace World crashed down, crushing the Nine Netherworld Hound.

The interference from the Void Realm Dao was ever-present, and no matter how the Old Man of Annihilation fought against it, he could not escape it.

With the assistance of these two realms, Cao Ya activated all sorts of Taoist techniques and supernatural powers, charging forward!

"Boom..." The clash between Cao Ya and the Old Man of Annihilation shook the universe and tore apart the laws.

The battle between the supreme quasi-immortal emperors disrupted the Great Dao, and their supreme energy crushed the river of time!

Even the Hong Emperor, faced with the magical power of these two, could only sigh in despair.

He even felt that the combined power of the three emperors was no match for either the World Dao Ancestor or the World Destroyer!

The commotion from their battle swept across the dark continent at the edge of the Boundary Sea, shaking the dikes on the other side, and causing the entire boundless Boundary Sea to tremble!

"A battle between quasi-Immortal Emperors!" Many Immortal Kings and prehistoric monsters all had grave expressions.

Let alone the two strongest auras, the rest, though seemingly concealed, are actually no match for them!

The immortals watching the battle through the light screen behind them couldn't see the scene behind the dam, but they could vaguely sense the aura of the Great Dao echoing in the endless distance, which made them tremble with fear.

“One of them belongs to the World Dao Ancestor! The other one… seems somewhat ambiguous?” The True Dragon frowned, racking his brains without finding a solution.

The Burial Master, the Lord of the Forbidden Zone, and others were equally puzzled. Who was this being who fought against the World Dao Ancestor? They somehow felt a sense of familiarity with him!

"At the end of the Boundary Sea, there are four Quasi-Immortal Emperors!" Meng Tianzheng said solemnly.

The existence of the other three emperors was also discovered by the immortal masters outside the world due to the fierce battle.

"The World Dao Ancestor and Shi Hao bear an immense responsibility."

"Can we really defeat the four Quasi-Immortal Emperors from the source of darkness and restore peace and order to the Boundary Sea?"

Everyone's expression was solemn.

They also realized that the downfall of the Imperial Era did indeed have a cause.

Everyone suddenly sighed. No matter what, they were still too weak. They weren't even Emperor Light Immortal Kings, so they couldn't participate in the battle at all!

If there were three or five more Emperor Light Immortal Kings... the current battle situation would undoubtedly be much better!

"I'll go! I'll do my best!" The burial master regretted it a little; he should have gone with him.

Just as he was about to set off, he noticed the strange changes happening in the distant Boundary Sea.

"That's... the Lord of the Fallen Emperor?" Everyone was astonished.

He's not dead?

The immortal kings in the Boundary Sea were all puzzled.

Because of that faint line of footprints, they knew they wouldn't mistake the Emperor of Fallen Kingdom.

That's clearly his aura!

Could it be that he has also fallen into demonic possession? But it doesn't seem likely, because there isn't that intense pressure!

At this moment, all the powerful immortals were itching to see the scene at the end of the Boundary Sea!

"Huff huff".

In the dark lands, heroes fought and slaughtered each other, their battles never ending, staining the heavens with blood.

Suddenly, a burst of fire appeared out of nowhere!

"You lingering spirit!" The head of the World Destroyer opened its mouth and bit down into the darkness.

The remnants of the Emperor's Fallen Ruler, now that they have been born, may they become his food!

With the power and resources of the Old Man of Annihilation, even the hidden tricks of a Quasi-Immortal Emperor would be difficult to pose a threat and would be completely wiped out.
