"You seem to have forgotten my existence!" Cao Ya pointed, and a large amount of sword energy and blade aura, mixed with wind, thunder, and lightning, rushed out.

Many divine skills and ultimate techniques were activated to attack and kill the World Destroyer!

"You've forgotten me too!" Emperor Hong sneered, his purple-gold crown protecting him. He formed hand seals and unleashed a supreme and profound technique, causing the chaotic energy to boil and erupt with a heaven-opening strike!

Cao Ya swayed slightly, revealing three heads and six arms. Two of his hands used techniques such as the Thirty-Three Heavens Creation Divine Fist, the Primordial Heavenly Dao, the Origin Divine Fist, and the Great Sun Tathagata Fist to fight against the Hong Emperor. Moreover, with the spread of cause and effect, the uncertainty of fate, the intertwining of water and fire, and the obscurity of life and death, and with the help of the Void Realm Dao and the Niwan Palace World, Cao Ya's power was able to forcefully injure the Hong Emperor!

"Wow." Emperor Hong coughed up blood, which was also covered with a purple-gold luster, making him extraordinary, sacred and inviolable.

A single drop of blood from a Quasi-Immortal Emperor is enough to pierce through the body of an Immortal King and change a world!

However, here, the Emperor's blood was spilled, and in the blink of an eye, it was extinguished by the supreme divine power of the heavens, leaving no trace of its wonder.

"Damn it! How can the Dao Ancestor of this world be so powerful? I am clearly the old-timer Quasi-Immortal Emperor!" Hong Di was furious and extremely puzzled.

After much thought, only the inheritance of the Immortal Emperor can offer some explanation.

"If it weren't for the Old Man of Annihilation, I'm afraid I would have been killed by the World Ancestor!" Emperor Hong took a deep breath.

Only after facing it firsthand did I realize how terrifying the World Ancestor was, no less than the Old Man Who Destroyed the World!

Of course, as a quasi-Immortal Emperor, Hong Di also has pride and will not easily admit defeat.

He is no match for them now, but once he joins forces with the Old Man of Annihilation to kill the World Dao Ancestor, devour him, and digest him completely... at that time, his foundation will greatly increase, and he will surely be able to reach the limit of the Quasi-Immortal Emperor realm!

"Bang!" Hongdi's will was as firm as iron, his Daoist magic roared, and he attacked Cao Ya directly, affecting many systems.

Emperor Hong pondered, "The power of the World Dao Ancestor has been dispersed. With the power of the Old Man of Annihilation, surely he can annihilate him?"

Beside him, the Old Man of Annihilation had already revealed his true form. His ancient Nine Nether Beast, which blotted out the sky and was far larger than a world, had fierce eyes, yet also contained a sense of vicissitude.

"Roar!" The nine heads of the Nine Nether Hound roared, unleashing their innate divine power of devouring the heavens and earth. This power could annihilate all laws, crush them into fragments, and then swallow them into their stomachs as food, further enhancing the power of this innate divine power and forming a virtuous cycle.

The bull horns on his head were as sharp as an imperial sword, simply unstoppable!

It is no exaggeration to say that the World-Destroying Elder's offensive power at this moment is unprecedented in the world. Even the three emperors would be severely injured if they clashed with him! Otherwise, why would they jointly haile the World-Destroying Elder as the "First Emperor Who Created Heaven and Earth" and even respectfully call him "Senior"?

"The old master's magic is unparalleled throughout history," Emperor Hong praised, while also observing carefully.

The Old Man of Destruction's cultivation is undoubtedly far more profound.

If one could glean some insight into his situation, even if he didn't have the power to secretly target the Old Man of Annihilation, his own cultivation might gain some enlightenment and allow him to advance further!

However, the counterattack by the World Dao Ancestor took Hong Di by surprise!

All that could be seen were the world ancestor's heads and remaining arms, all forming unique hand seals.

"Boom..." One loud sound after another shook the universe, and the heavens and earth trembled.

In an instant, divine winds howled, flames scorched the sky, celestial thunder roared, light shone brilliantly, darkness deepened, ancient caves were lifeless, space collapsed, time was chaotic, sword intent arose from all directions, and blade light descended from the heavens and the earth...

There were so many spells that even Emperor Hong was a little overwhelmed.

These laws and rules are all powerful, encompassing hundreds of great principles.

The simultaneous activation at this moment was utterly astonishing, destroying the cosmic order and shattering the space-time continuum!

"Thump!!" Several impacts were heard, and the Old Man of Annihilation let out a muffled groan as his head split open, black blood flowing down.

Under the counterattack of the World Dao Ancestor, the Old Man of Annihilation was actually injured, and all nine of his heads were collapsing!

Upon seeing this, even Emperor Hong couldn't help but gasp.

Keep in mind that this was even with him also intervening, involving the World Ancestor's Dao of Cause and Effect, Dao of Destiny, Dao of Life, Dao of Death, Dao of Water, and so on, yet the Old Man of Annihilation still lost. If he hadn't intervened, wouldn't that have been...

At this crucial point, Emperor Hong's heart sank.

The strength of the World Dao Ancestor is simply unbelievable!

"Azure Emperor, Feather Emperor, are you done yet?" Hong Emperor roared. At this moment, he could only hope that the two quasi-immortal emperors would return victorious and join the battlefield.

With two more fresh forces joining the fray, Emperor Hong believed that they would still be able to defeat the World Dao Ancestor.

However, neither the Azure Emperor nor the Feather Emperor were able to defeat the Five Kings and Shi Hao.

"Whoosh." Especially deep within the dark region, a flame appeared.

"That persistent ghost." Emperor Hong's face was cold. The remnants of the Emperor's Fallen Ruler had actually deceived them... Normally, even if this flame were to appear, it wouldn't have much of an impact and could be extinguished with a flick of the finger. But in the heat of battle, when the enemy sends reinforcements, the entire situation inevitably becomes worrisome.

"Never mind that! The most important thing is for us to join forces and kill the World Dao Ancestor first!"

The old man who was about to destroy the world shouted and used a healing spell, instantly restoring him to his original state.

However, he had already sensed the terror of the World Dao Ancestor and knew the complexity and strangeness of this person's supernatural powers. He was thinking of countermeasures and how to break through.

"Don't worry about me, go help Xiaota and the others." Cao Ya also shook his head.

"Whoosh." The flame immediately drifted away and suddenly burned towards the Azure Emperor.

It wasn't that Cao Yan was arrogant and didn't need reinforcements, but rather that in his battles with the Annihilator and the Hong Emperor, a single, incomplete Emperor Flame was unlikely to be enough to deliver the decisive blow—especially when he intended to kill the Annihilator!

On the contrary, with the help of the Five Kings and Cao Ya from the two worlds, Remnant Fire and the Five Kings have a chance to defeat the Azure Emperor!

Only in this way can we defeat the enemy and win the victory.

Cao Ya was confident that he could easily take on two opponents at once, and he could even hold out for ten thousand years!

"The main problem is that the Old Man of Annihilation is too strong. If he had the same magical power as Emperor Hong... I would have won by now!" Cao Ya sighed inwardly.

He showed no signs of impatience, proceeding steadily and slowly to wear down the divine beast shell of the Nine Nether Hound, and incidentally pierce through the Hong Emperor, severely injuring him!

Cao Ya used all the laws and supernatural powers without holding back, reaching the pinnacle of their power!

At this point, in terms of combat power, he had reached the absolute limit of the six-star peak!

Even if a Celestial Emperor at the initial stage of the Seven Stars were to arrive, he wouldn't be able to defeat him within a hundred moves!

The Way of Fire, the Way of Water, the Way of Wind, the Way of Lightning, Body Refinement, Cause and Effect, Destiny, Time, Space, Life, Death, Reincarnation, the Way of the Sword, the Way of the Blade...

Countless mysteries intertwined at the summit of the heavens, activated by Cao Ya, neutralized the innate divine power and killing techniques of the Old Man of Annihilation, and even injured the divine beast body of the Nine Nether Hound!

In comparison, the threat posed by Emperor Hong was much smaller. He could only barely hold on under Cao Ya's magical power, and he was in grave danger, spitting out blood repeatedly. Even his purple-gold imperial crown began to crack.

It must be said that the effects of the Void Realm and the Niwan Palace World are also very obvious.

Otherwise, if those two were at their peak, Cao Ya wouldn't have been able to kill them so quickly.

"Within the Boundary Sea, there is someone who has gone further than I have at the Quasi-Immortal Emperor realm?!"

The Old Man of Annihilation looked grim, but despite his best efforts and with the help of the Hong Emperor, he still could not suppress the World Dao Ancestor.

The difference in strength between the two is obvious at a glance.

"Emperor Cang, Emperor Yu, they must win at least one match, right?" Emperor Hong hoped.

After all, none of their opponents were quasi-Immortal Emperors!

"Bang bang bang!!!" Over here, World Dao Ancestor Cao Ya, with boundless divine might and the Great Dao emerging one after another, used his cultivation level alone to beat down the World Destroyer and the Hong Emperor.

On the other side, the Willow God, the Little Pagoda, the Chicken Farmer, the Fake Medicine Seller, and the Butcher—the five Emperor Light Immortal Kings—struggled to entangle the Azure Emperor.

Fortunately, the Void Realm and the Niwan Palace World followed him like a shadow, creating a binding effect on the Azure Emperor; otherwise, the five kings would have already been defeated and killed!

But if things continue like this, they will inevitably be defeated one day.

In a contest of attrition, how could they possibly outlast a Quasi-Immortal Emperor?

"Sizzle." The two quasi-immortal emperor artifacts, the bone ruler, and the bone seal of the Azure Emperor were all snow-white and had a sacred aura.

The weapons and supernatural powers of the five kings were almost powerless against the cutting of the bone ruler and the bombardment of the bone imprints, like ice and snow melting away. Even when they joined forces, they could only manage a draw.

The situation only changed after the remnants of the Emperor's Flame fell.

"Boom!" Just then, more skeletons flew out from the depths of this dark place.

That was also a legacy left by the Emperor of Fallen Kingdom. Knowing that he alone could not solve the Black Calamity, he specially arranged a backup plan before his death to provide assistance to the future emperors.

"Buzz." The remnants of the emperor's bones merged with the small tower, and instantly, this ancient, broken emperor tower began a new round of transformation, getting closer and closer to the quasi-immortal emperor realm.

However, the imperial fire drifted into the radiant light of the Willow Goddess, helping her cultivation to leap forward!

The strength of these two immediately increased dramatically, and the attacks of Willow Branch Green Shadow and Emperor Tower began to put considerable pressure on the Azure Emperor.

"Don't worry, senior. We will fight to the death to drag the Azure Emperor down with us!" said Liu Shen.

A stunningly beautiful figure spread her hands, and billions of green lights floated, unusually enveloping the flames. Wood and fire overlapped, the Daoist charm was perfected, and the imperial glow became even more perfect.

"Die!" Little Tower roared, his grief and rage making him want to kill the Azure Emperor immediately!

"Heavenly Emperor!" the butcher sighed. He had never had the chance to meet this ruler in the past, but now that he had met him in person, he only had a fragment of his soul left.

The butcher was filled with rage at the thought of the Heavenly Emperor's majesty and the glory of the Emperor's era!

The era has crumbled, and almost all the people of the past are dead.

"Whoosh!!" The butcher drew his bow and arrow, gathering the essence of the universe to create supreme divine arrows, each capable of piercing through an entire world!

Chicken farmers and counterfeit medicine sellers also exerted all their strength, manifesting all kinds of magic, and together with the three kings, they attacked and killed the Azure Emperor!

"You little rascal." The Azure Emperor sneered, glancing at Willow God and Little Tower with utter disdain.

"At his peak, he was killed by us. Now he only has a remnant of his original power. Does he think he can turn the world upside down? What a joke!"

The Azure Emperor unleashed a bone imprint, as white and pure as mutton fat jade, crushing the principles of divine medicines and immortal herbs, the divine essence of celestial birds and beasts, and those divine arrows of heaven and earth.

"Cough cough." The fake medicine seller, the chicken farmer, and the butcher were all seriously injured, bleeding profusely.

Immediately, the Azure Emperor, wielding a bone ruler in one hand, was invincible, overturning the small tower and severing the countless willow branches.

Even with the help of some of the energy from the World Dao Ancestor and the Emperor Fall Ruler, the five Great Emperor Light Immortal Kings, working together, still suffered a crushing defeat.

The power of a Quasi-Immortal Emperor is undeniable! It far surpasses that of an Immortal King!

"Whoosh." But just then, a nine-colored sword light flew in from afar.

It turned out that Cao Ya, seeing the situation was dire, drew his sword to save the five kings.

He has the advantage in the battles against the Old Man of Annihilation and the Hong Emperor, and can certainly lend a helping hand within his power, depending on the situation on other battlefields.

These are all future Immortal Emperor seeds, the main force to deal with the strange races, and they cannot perish here!

After all, they wouldn't have come if Cao Ya hadn't invited them.

Even when Shi Hao ventured deep into the Boundary Sea to quell the Black Calamity, it was many tens of thousands of years later, not in the present.

Since Cao Ya had launched his attack ahead of time, he naturally had to make various preparations in case of any unforeseen circumstances.

Furthermore, Shi Hao and the five Immortal Kings must be taken care of to prevent any accidents from happening.

Cao Ya did indeed possess this ability, occasionally unleashing a deadly move that not only harassed Cang Di and Yu Di, but also caused injuries to their immortal bodies!

"Crack." Even a quasi-immortal emperor artifact developed cracks, and its Daoist essence was damaged.

"Both the Void Realm and the Niwan Palace World need to be strengthened." Cao Ya thought to himself. If the two realms were stronger, he wouldn't need to help them from afar, and the Five Kings would be able to kill the Azure Emperor.

Unfortunately, the Void Realm Path originates from the [Snow Eagle Lord] universe; although there are multiple fellow practitioners in the Niwan Palace world, it is extremely difficult to advance one's realm using this method.

"The Annihilator and Emperor Hong, what are you doing? The two of you joining forces, yet the World Dao Ancestor still has the spare power to deal with me?" Emperor Cang was furious.

The two men had cold expressions, but they had no way to express their grievances.

"How about we switch?" Hongdi said irritably.

The Azure Emperor fell silent.

He wasn't blind; he saw all the terrifying power of the World Dao Ancestor.

The old man who destroyed the world was incredibly powerful. Even with the assistance of the Hong Emperor, he was still no match for the World Dao Ancestor. He and the Feather Emperor had to wait until they defeated a group of Emperor Light Immortal Kings before joining the battle, and then the four emperors would surround and kill the World Dao Ancestor...

He didn't want to be beaten into a dead dog by the World Dao Ancestor!

"Don't think that just because you have the World Dao Ancestor, you can stop me! You're far from it!"

The Azure Emperor cruelly said, "Although the bone imprint bears the sword mark of the World Dao Ancestor, its essence is still at the Quasi-Immortal Emperor level, which is no small matter."

That bone ruler, capable of weighing heaven and earth and cutting through the universe, is equally unfathomable.

"Is that the profound mystery of a Quasi-Immortal Emperor?" Suddenly, the Butcher felt something.

His bow and arrow trembled slightly, as if sensing something. The cosmic essence it contained became even more concentrated, like a supreme divine weapon revealing boundless sharpness.

"Death without destruction, rebirth through nirvana!" Liu Shen murmured. Her own experiences, combined with some inspiration from the Emperor's Fire, and the heavy pressure from the Azure Emperor, stimulated her and led her to comprehend the path of a Quasi-Immortal Emperor.

In an instant, the willow branches fluttered, and an atmosphere of thunder and fire across the sky and immortal green wood was released.

There was also the small tower, whose essence was extremely high in the past, and which now incorporates the remnants of an emperor's bones, and it was also touched.

These three individuals have taken another step forward from the realm of Emperor Light Immortal King. If the circumstances were not unfavorable, they could recuperate for tens of thousands of years and then attempt to break through to the Quasi-Immortal Emperor realm!

Naturally, the attacks from Willow God, Little Tower, and Butcher became much fiercer, making the Azure Emperor sense the approach of death.

The fake medicine seller and the chicken farmer were his henchmen, waiting for their chance to act. Just like the two worlds, one real and one illusory, they distracted the Azure Emperor, creating an opportunity for the three heroes to kill him!
