"Even if my master were to be resurrected, I'd still have to be serious, wouldn't I?" Cao Ya muttered. The Ten Ancient Fiends, such as the Female Kunpeng and the Thunder Emperor, were not yet Immortal Kings, but rather at the pinnacle of True Immortals. Each of them could easily defeat three to five Immortals without much difficulty, and could be easily suppressed and killed.

The nine immortals joining forces... might win, but it certainly won't be an easy victory!

As for Cao Ya's combat strength, to be honest, it is still inferior to that of her mentor, the female Kunpeng.

The only saving grace is that Cao Ya's extraordinary system is numerous and can be dispersed to resist many immortals.

The group of immortals were also shocked. Cao Ya's performance was truly unexpected; he had actually managed to block the combined attack of all nine of them single-handedly. This was simply...unbelievable!

"As expected, our decision to surround and kill Cao Ya was absolutely correct!" the immortals muttered to themselves, their eyes cold and menacing, as they stepped forward and pressed forward.

To outsiders, Cao Ya, who was able to create his own world law, was indeed the "Ancestor of the Dao of the World." His comprehension was unparalleled, and even immortal kings might not be able to match it!

Such beings, if we don't eliminate them before they fully rise to power, are we really going to wait for them to break through and become kings?!

From the perspective of another realm, a true immortal is indeed powerful enough, but without becoming an immortal king, they are ultimately lacking.

"boom……"

The immortals erupted, divine light shone, and radiant glow covered billions of miles. The Great Dao boiled, burning the sun, moon, and stars within this vacuum, refining wisps of stellar essence, which either entered their bodies or contained their will. Like ferocious beasts baring their fangs and claws, they flew towards Cao Ya, drawing an eternal trajectory, like a falling comet!

In fact, there are various remains in outer space, all of which have been melted down.

"I have to admit, Cao Ya, you are a great threat to my realm! Allowing you to live is irresponsible to my realm!" The purple-haired female immortal spoke, her voice chilling.

"Eliminate him! Our realm is invincible throughout history, sweeping across all heavens. Even the Immortal Realm dares to close its doors and avoid our edge... Heh, what 'World Dao Ancestor'? He can't escape the word 'death'!"

The direct descendants of the immortal kings of the Crimson King Clan, Anlan Clan, and Yutuo Clan, after becoming immortals, were arrogant and domineering, yet harbored a hint of jealousy. Their gazes were icy, and their murderous aura was overwhelming as they besieged Cao Ya!

"Who is strong and who is weak depends on strength, not words." Cao Ya murmured, his Heavenly Desolate Halberd sweeping across, following the phantom of the Kunpeng in attack. That was the Kunpeng Treasure Technique, and faintly visible were six black holes capable of devouring everything!

In his three-headed, six-armed state, Cao Ya utilized all his extraordinary abilities.

The sword energy was vast, and various sword intents filled the air, giving the group of immortals a surprise and almost causing them to be injured.

The blade's aura was gleaming, its killing intent fierce and ruthless, cleaving through three thousand realms. Combined with the vast death energy, it swept across billions of miles, causing even immortals to change color.

Moreover, within that scene, multicolored lightning exploded, light and darkness intertwined, wind and fire roared, celestial rivers flowed, and enormous Buddhist and Taoist images chanted ancient mantras…

Boom!!!

The battle was fierce and terrifying. On the outer battlefield, stars exploded, and celestial light rose, illuminating the entire desolate borderland as if it had existed since time immemorial.

Although Cao Ya was strong, he was not afraid of the other side. The nine immortals attacked together, unleashing their own immortal artifacts, which contained immortal radiance, intense and blazing!

In an instant, the three-eyed immortal divine eye, the purple-haired woman's immortal sword energy, the Crimson King Clan's immortal time magic, the Yu Tuo Clan's immortal giant hand, and the An Lan Clan's immortal spear...

All the supernatural powers of everyone roared out and rushed towards Cao Ya, tearing through the void!

Cao Ya's various magical powers spread throughout the ten directions, layer upon layer, exuding a unique aura of the Great Dao, blocking the immortals from the other realm. The aftershocks shook and shattered the sky, and even the Heavenly Abyss showed signs of disturbance!

"So powerful..." The group of immortals were horrified, their eyes filled with a chilling, cruel light.

"It seems he's almost comparable to a quasi-immortal king or a quasi-immortal king? In a one-on-one fight, perhaps only He Wushuang from the late Immortal Ancient Era could suppress him!"

"And He Wushuang is now at the King Realm! Moreover, he received instruction from an ancient ancestor of our realm and was taken as a personal disciple! Cao Ya, on the other hand, did not have He Wushuang's opportunities and reached the True Immortal Realm at a much younger age..."

The immortals quickly transmitted their thoughts, and in an instant, their determination to kill Cao Ya became even stronger!

This ruthless character cannot be allowed to live! He will be a deadly threat to the foreign lands in the future!

The ancestral spirits of the ancient times, the True Dragon, the leader of the Ten Fiends, the Immortal King of No End, the Immortal Monk King, the Reincarnation Immortal King, and other immortal kings from the Nine Heavens and Ten Earths have all caused considerable damage to the foreign lands.

If it weren't for the fact that there were more kings who could gang up on them, and that there were also giant-level immortal kings like Wu Shang leading the charge, it's very likely that the alien realm would have been defeated back then.

Cao Ya was serious. Facing nine opponents alone, he dared not be careless and was extremely cautious. He did not leave any power to protect himself, but instead unleashed all his strength to directly confront the immortal divine power!

"I possess the True Phoenix Treasure Technique, whose healing abilities are second to none in the world. I have no fear of exchanging injuries for injuries..." Cao Ya thought to himself, as long as he has a breath left, he will not die!

The existence of the Niwan Palace world not only enhanced his defensive and offensive capabilities but also provided him with top-tier energy replenishment. He didn't worry about running out of mana in the final battle, thus preventing him from using the True Phoenix Treasure Technique, which could lead to severe injuries and a tragic end.

"Boom..."

Beyond the heavens, the light is dazzling and beautiful, yet it contains immense killing intent. Even supreme beings who come into contact with it will bleed and find it difficult to survive!

On the desolate frontier, all the cultivators were engaged in a bloody battle, but they had no energy to pay attention to the terrifying aura coming from beyond the realm. They knew that in the depths of the star sea, the True Immortals and Immortals must be engaged in the same life-or-death battle!

In the Supreme Battlefield, the Escape Battlefield, the Battlefield of Slaying Me, the Battlefield of the Void Path, and the Battlefield of the Heavenly God, the Imperial Pass side is mostly at a disadvantage, only gaining an advantage in certain areas.

There was no way around it; at the same level, the number of beings from other realms was simply too far ahead. The only Supreme Battlefield where the lead was relatively small was the Imperial Pass, where the old man Qingmu, the old woman, Kunpengzi, Qi Daolin, the old celestial being, and others were beating up the Supreme beings from other realms!

In the True Immortal Battlefield beyond the realm, Cao Ya fought nine against one, and Meng Tianzheng fought three against one, both instances of fighting against overwhelming odds.

However, both of them were extremely powerful, top performers among their peers. Even in the face of danger, they remained fearless. Thanks to the existence of the *True Phoenix Treasure Technique*, they were not afraid of accumulating injuries. If danger struck, they would simply endure it, relying on the energy of their Niwan Palace world to rise from the ashes like a phoenix!

"Fortunately, the World Dao Ancestor's side has also held on." Meng Tianzheng breathed a slight sigh of relief, but was also surprised.

The fighting power of the World Dao Ancestor has exceeded expectations time and time again!

The three immortals opposite him had ashen faces. Even with their combined strength, they had failed to kill Meng Tianzheng. Could it be that they were not even as good as a newly promoted True Immortal?

Of course, after scanning the battlefield with their divine senses, the three immortals immediately felt much more comfortable.

While a three-on-one advantage isn't significant, it's still slightly better than a nine-on-one situation where the outcome is evenly matched.

"Hoo~~ We are immortal beings, how can we degenerate and compete in rottenness instead of striving for excellence?"

The three immortals exchanged a glance and nodded silently.

"First, eliminate Meng Tianzheng, then kill Cao Ya, and then assist the three kings in breaking through the Primordial Imperial Pass!"

"In this way, we, who have made great contributions, will surely gain the favor of the king, be granted secret techniques, and be personally instructed! At that time, we will be on the verge of becoming immortal kings, and like He Wushuang, we will transcend the realm of immortality and ascend to the realm of kings!"

"Moreover, within the Nine Heavens and Ten Earths, there must be great fortunes left behind by ancient immortal kings..."

They roared, driven by the need for battle merits, the greed for the Immortal King's relics, and a sense of pride, charging towards Meng Tianzheng with all their might. Terrifying shockwaves echoed, like a galaxy exploding!

"Whoosh!!!"

Meng Tianzheng drew his bow and shot arrows. The power of the world condensed, and arrows rained down. Each arrow was a celestial artifact, capable of piercing through immortal beings, making them take it seriously as if facing a formidable enemy.

"Although the World Dao Ancestor blocked the nine immortals, the pressure on him must still be immense!"

"I need to deal with the enemy in front of me as soon as possible, and then go to help the World Ancestor..."

"As long as the two of us are free, we can end the war in the borderlands!"

"Finally, we'll head to the Primordial Imperial Pass to support the King and fight against the three kings from the alien realm..."

Meng Tianzheng changed his mind, let out a long roar, and blood seemed to seep from within the longbow, as if some kind of life form had been nurtured by him all along, and today, he was finally going to use it in its entirety without reservation.

That was the result of Meng Tianzheng's "using his own body as a seed" journey. Although he ultimately failed, he did not gain nothing. However, for safety reasons and other considerations, he took out the result and placed it in his longbow to nurture it, hoping that one day he could set foot on this path again and attain immortality!

Now, relying on the Creation Law and the Niwan Palace World, he has become comparable to a true immortal.

The fruit within the longbow, though still important, could no longer fundamentally affect Meng Tianzheng.

Even if it has an impact, Meng Tianzheng won't care. The most urgent task is to deal with the immortals!

For this, Meng Tianzheng is willing to pay any price, even if it means cutting off his future or dying on the spot!

Of course, even if Meng Tianzheng retrieves the fruits of his cultivation from years past and goes all out, it is destined to be a difficult battle, extremely fierce, with blood splattering and containing celestial radiance that can pierce through the stars!

The combined power of the three immortals and the display of the power of the three immortal artifacts posed an exceptionally great threat to Meng Tianzheng. If it weren't for the True Phoenix Treasure Technique, which saved him from danger several times and almost reborn him from the brink of death, he would probably have perished!

"Damn it, that's one of the Ten Ancient Fiends, a treasured technique of the Phoenix lineage, possessing the strongest healing power!" The three immortals' faces were grim, with a hint of greed in their eyes.

Who wouldn't want to obtain such top-tier divine techniques?

"The Niwan Palace World and the True Phoenix Treasure Technique are the key reasons why I was able to rival the three Immortals so soon after entering the True Immortal Realm!" Meng Tianzheng muttered to himself, growing stronger with each battle, actually turning the tide of the fight and launching a fierce attack on his enemies. The three men looked extremely angry, yet also filled with astonishment and uncertainty.

"Useless thing! Even Meng Tianzheng, who has only been a True Immortal for a few days, couldn't take it down!"

On the side, through divine sense observation, they saw the situation on another immortal battlefield, where the nine immortals looked very unhappy.

Of course, their own battle situation wasn't much better; nine against one, it was a close contest!

"Everyone, if we hold back any longer, we will become a laughing stock in the True Immortal Realm!" the Three-Eyed Immortal transmitted his voice, and his third divine eye shot out white light, piercing through the void!

"If the three kings were to take notice of this battle, they would likely be very displeased and will be punished afterwards!" the purple-haired immortal woman murmured, her longsword in hand, her sword intent fierce, but each time it was extinguished by Cao Ya's endless sword light, and she failed to achieve anything.

Without a doubt, the purple-haired immortal woman frowned, finding it troublesome, and was also very curious about Cao Ya's swordsmanship!

"Among them, it seems there's the true meaning of the 'Grass Character Sword Technique' from the Nine-Leaf Sword Grass, one of the Ten Ancient Fiends of the Nine Heavens and Ten Earths, and the other sword intents..." The purple-haired immortal woman was envious. Cao Ya truly possessed immense good fortune; he had more than one of these top-tier divine techniques at his disposal!

"Kill him, and these precious techniques will be ours! We can conquer the Nine Heavens and Ten Earths, and who knows what other great gains we'll make!" The purple-haired immortal woman thought to herself, her desire growing stronger as she broke through the Imperial Pass and invaded the Great World on the other side!

The remaining seven immortals, whether from imperial clans or other races, all knew that what the three-eyed immortal and the purple-haired female immortal said was very reasonable.

The immortality of the imperial family does not mean that they will receive high regard from the immortal king!

Unless there's a chance to break through to become a king!

"Kill Cao Ya, and I'll be extremely envious of his Creation Technique, as well as his sword and saber manuals and treasures!" The immortal of the Anlan Imperial Clan licked his lips, his eyes filled with greed, and threw the spear in his hand, pointing it directly at Cao Ya!

The immortal Yu Tuo imperial clan, with its outstretched hand covering the starry sky, its scales and armor reflecting a cold light.

The immortality of the Crimson King Imperial Clan, when activating their innate divine abilities, allows the flow of time's power, profound and mysterious.

Add to that the immortal divine light of the three-eyed immortal and the immortal sword aura of the purple-haired woman…

Cao Ya wielded the Heavenly Desolate Halberd, clashing with the Immortal Spell, the resounding boom shaking the heavens!

"Bang bang!!!"

Various divine lights collided, laws surged, and ten figures flickered, spilling blood. All of them suffered severe injuries, their bodies cracked, and their souls seemed to dim.

"True Phoenix Treasure Technique! Infinite Rebirth!"

Cao Ya roared inwardly, as if a phoenix was soaring. Flames flashed, and all his injuries were instantly healed, leaving him completely unharmed. Only his Niwan Palace world had lost a lot of energy.

"Come on, let's keep fighting!"

Cao Ya laughed. With the True Phoenix Treasure Technique and the Niwan Palace World constantly providing energy for Nirvana, even the most serious injuries could be repaired, and he would soon regain his peak combat power and sweep away all the powerful opponents!

Of course, Cao Ya was also aware that using the True Phoenix Treasure Technique to be reborn in fire too many times in a short period of time would inevitably damage his Dao foundation and be detrimental to his future. It might take an extremely long time to continuously nurture and absorb rare and precious materials to make up for the deficiencies.

But he had no other choice; otherwise, how could he contend with nine immortal beings?!

Cao Ya's only thought was to wear them down.

To really defeat them one by one... honestly, it's almost impossible. Which immortal immortal doesn't have a strong ability to protect themselves?

Most importantly, if all power were gathered specifically to target one or two immortals, with the intention of annihilating them...

With Cao Ya's combat strength, it was indeed possible to achieve this. However, the remaining six or seven immortals wouldn't stand idly by; they would unleash their ultimate techniques to attack Cao Ya. At that point, even the True Phoenix Treasure Technique might not be able to save Cao Ya; it might exceed his limits, causing him to perish on the spot, body and soul.

The True Phoenix Treasure Technique is indeed a divine healing technique, but it is not invincible. Otherwise, the Phoenix lineage among the Ten Fiends would not have died in the Immortal Ancient Era, and now it is almost impossible to find a Phoenix with pure bloodline!
