Cao Ya guessed that these three Immortal Kings were definitely considering Tianyuan, the Primordial Imperial Pass, and the King, and were discussing countermeasures—whether to fight or retreat.

"None of these three are powerful figures. They have little hope of breaking through the Primordial Imperial Pass, traversing the Heavenly Abyss, or killing a King..."

Cao Ya thought to himself, although the foreign lands are powerful and at their peak, with many immortal kings, they all have their own missions and it is impossible for them all to come to the borderlands.

Of course, if they really had the time and all came, then it would be all over. Putting aside the fate of Tianyuan, the Primordial Imperial Pass would definitely be breached, and the king would fall.

"Our realm has swallowed so many worlds and countless races, all of whom are outsiders. We must leave behind a group of immortal kings, such as Brother Wushang, to guard the world."

An Lan shook his head and explained, "It's not only to guard against the powerful figures in the Boundary Sea, but also to monitor those races, such as the Gu Clan, the Fallen Blood Phoenix, and the Fallen Ancient Monk who have defected from the Nine Heavens and Ten Earths."

"As for Brother Red King and the others, they are either in seclusion cultivating for millions of years without ever emerging, or they have encountered danger and injuries and are still recuperating, and their habitat has been sealed off, so it is impossible for them to come."

"The three of us are enough to handle everything. If we were to ask for reinforcements, wouldn't those fellow cultivators look down on us?" Bracelet

Finally, An Lan countered by asking why Yu Tuo should be persuaded to seek help by appealing to his emotions and reasoning with him.

The blue-haired giant nodded. There were many kings from other realms, each with their own missions. Including those who had ventured deep into the Boundary Sea to seek breakthroughs, as well as those who were recuperating or in seclusion, there were quite a few left. However, after leaving a few behind, only the three of them could be dispatched to the borderlands for the time being.

"No need to rush. I have already notified Brother Wushang and the others. They are handling various matters and monitoring the defecting powerful figures for any unusual movements. Once they have some free time, they will secretly come and lie in wait somewhere, ready to strike suddenly when the opportunity arises," the blue-haired giant transmitted his voice.

Yu Tuo knew that this was the reasonable measure, taking into account both the remote border regions and the safety of the world.

But he just couldn't swallow this insult; he was extremely resentful!

Yu Tuo was severely injured by the Primal Emperor Guan Wangzhe and Tianyuan, both of whom were at the king level. He didn't think much of it. How could he not bleed when fighting against a Celestial King?

The problem is, his palm was slashed by Cao Ya, his scales fell off, and it almost broke... bracelet

This is a great disgrace to the Immortal King!

Yu Tuo was furious, wishing he could storm into the Primordial Imperial Pass on the spot, suppress Cao Ya, bring him back to the foreign land, and torture him with all sorts of cruel methods!

"Don't rush. They can't make any waves in the nine heavens and ten earths; they are destined to perish."

An Lan transmitted his voice, carrying a chilling tone, and said, "When the time comes, we can kill Cao Ya with a flick of our wrist. So what if he's a top-tier True Immortal? In front of us kings, what difference is there between him and an ant?"

The blue-haired giant also spoke up: "To get angry at a weak True Immortal, Brother, you're being too attached to appearances."

Yu Tuo nodded. Although he still harbored hatred, he had also broken free from his stubbornness. Without the protection of the Primordial Imperial Pass and the Heavenly Abyss, he could easily crush Cao Ya with a single move, splattering blood and flesh everywhere.

There's really no need to treat him as an enemy.

"That little beast Cao Ya isn't qualified to be my enemy!" Yu Tuo whispered.

"Don't think that this Primordial Imperial Pass, or the Heavenly Abyss, can protect you forever," An Lan said coldly. "Even if you cower like a tortoise, one day we will shatter your shell and destroy everything you possess!"

"Heh, just wait and see, that day will come," the blue-haired giant sneered.

Immediately, the three immortal kings glanced at the Primordial Imperial Pass with cold eyes, then simultaneously withdrew, leaving the place and returning to the borderlands to oversee their camps.

The cultivators from other realms were extremely respectful; even the supreme beings bowed and scraped as they stepped forward to greet them.

"Three immortal kings, relying on the Heavenly Abyss, should be able to hold them off, right?" Cao Ya pondered on the city wall of the Primordial Imperial Pass.

The king nodded and said, "Tianyuan is the real trump card, the greatest asset of our realm. Even if three more Immortal Kings came, we could still stop it! But..."

With that, the king let out a soft sigh.

Cao Ya felt heavy-hearted, knowing the king's worries. There were far more than six immortal kings surviving in the foreign lands! After they resolved some hidden dangers, they could either awaken a group of sleeping immortal kings or have an immortal king who had been recuperating in seclusion emerge. They could easily reach double digits!

Among them are even giant-level Immortal Kings like Wu Shang!

"At the end of the Immortal Ancient Era, the alien realm launched a massive attack, and many Immortal Kings were mobilized. In the past and present, there have been very few Immortal Kings who have come to attack again." The king smiled bitterly and said, "Should we be glad that we are weak and not valued, or should we be sad?"

The one-armed old man stood by, feeling aggrieved. When did the Nine Heavens and Ten Earths fall to such a state, losing all its former grandeur?

"We still need to become stronger and improve the overall power of our realm!" Cao Ya murmured. "Like in the Immortal Ancient Era, when multiple True Immortals and Immortal Kings appeared, along with giants, and even supreme giant-level Immortal Kings..."

The king's expression flickered strangely for a moment, then he shook his head and said, "The Immortal King realm is not easily attained. Even for geniuses and prodigies, it takes millions, hundreds of millions, or even one or two epochs to advance. And this is just an ordinary Immortal King; breaking through to the pinnacle of Immortal Kings takes even longer, measured in epochs, and it's unknown how many billions of years it will take."

"A Celestial King giant, huh..."

The king sighed, "Those kinds of people would be considered to have profound foundations even in great realms like the Immortal Realm or the Otherworld."

"And the supreme giants... perhaps, the original ancestors of the Immortal Realm and the Other Realm, if they were still alive and had not died, might be at this level."

"Deep within the Boundary Sea, the butcher, the chicken farmer, and the fake medicine seller, who are renowned far and wide and fearsome, must be an Immortal King of unparalleled power!"

As the king spoke, a hint of expectation inevitably crept in as he said, "If an unparalleled giant were to emerge in our realm, we would be able to sweep across the foreign lands and turn the tide of defeat."

Cao Yaxin said that the development in the original book is basically like this.

Shi Hao rose to power, using his unparalleled magical strength to resolve everything and eliminate the alien realms. Although he received help from some Immortal Kings of the Immortal Realm and revived some ancient powerhouses from the Nine Heavens and Ten Earths, most of the time, Shi Hao relied on himself, and only himself!

"Now, the First Elder Meng Tianzheng, who was not taken away by the darkness, has already become an immortal. He is an unparalleled hero. Let alone an Immortal King, given enough time, even becoming a Quasi-Immortal Emperor is not impossible!"

Cao Ya pondered that in the [Sacred Ruins] timeline, Meng Tianzheng was a Quasi-Immortal Emperor at the peak, incredibly powerful, and a Quasi-Immortal Emperor who had suppressed and killed many strange races. He was invincible among those of the same level!

"Moreover, the pillar of the Nine Heavens and Ten Earths right now is this king, is me, is Meng Tianzheng."

"Shi Hao is only at the Void Dao Realm, there's no need for him to bear too much pressure or shoulder too much responsibility."

"We'll discuss this matter again when he becomes a supreme being, or even a true immortal."

Cao Ya thought to himself that it was not impossible for him to break through to the six-star Immortal King level by relying on the ancient immortal method, the ancient and modern method, or the creation method, but the time required would be extremely long and incalculable.

Fortunately, the other Cao Ya individuals, each cultivating different extraordinary systems and following vastly different cultivation paths, can share power through the system space. Their combined strength still offers hope that, at some point, their combat power will surge to rival that of a Celestial King!

Characters like Cao Ya from "Covering the Sky," "The Legend of the Shepherd," and "The Supreme Being" are comparable to true immortals in this world.

Give them time, and one person alone can rival the pinnacle of a true immortal, and then combine all kinds of magical power...

Cao Ya was quite excited as he thought about it. He would definitely pay attention to his own cultivation and not let others down.

"The war between the two realms is about to break out," the one-armed old man said in a deep voice, feeling that he was not very confident.

"Those immortal kings are definitely waiting for the alien realm to win, break through the imperial pass, and invade the Nine Heavens and Ten Earths... Even if we can still stop them here, it's useless."

The one-armed elderly man frowned, pondering a solution.

"There will be a way," the king said softly, glancing at Tianyuan. If all else failed, he would have to detonate Tianyuan to buy time.

However, even the king has his worries. After the Heavenly Abyss explodes, it can indeed stop the invasion of other realms, but after a few thousand years, or at most tens of thousands of years, when the storm of laws subsides, beings such as supreme beings and immortals will be able to cross realms, and there will also be immortal kings...

Could the Nine Heavens and Ten Earths at that time match the peak combat power of the foreign land?

Although they already have two True Immortals, Cao Ya and Meng Tianzheng, who are comparable to immortals, even if they join forces, they are no match for a king.

"Once we repel the alien army, we won't have to take any risks and can maintain the status quo that has lasted for billions of years," Cao Ya said. He had previously caused a great disturbance in the alien camp, killing twenty or thirty Supreme Beings and countless invading cultivators. With the aftermath of the battle wiped out, the pressure on the Imperial Pass had been greatly reduced.

The one-armed old man seemed to know Cao Ya's thoughts, shook his head, and said with a wry smile, "World Dao Ancestor, your actions just now were indeed remarkable, but the problem is... the other realm is glorious and has not declined. With a single command from the Immortal King, not to mention dozens of Supreme Beings, even hundreds of Supreme Beings can appear here!"

Cao Ya's heart sank; this was indeed a major hidden danger.

Regardless of realm—whether Celestial God, Void Daoist, One-Transcending, Supreme, True Immortal, or Immortal King—the number of cultivators of the same level from other realms far exceeds that of the Nine Heavens and Ten Earths!

He knew very well that before the great battle broke out, immortals from the alien realm would definitely arrive to fight against him and Meng Tianzheng, leaving them no time to focus on killing the alien realm's supreme beings.

As for starting a war now...

Those three immortal kings aren't just sitting idly by; how could they possibly stand idly by?

When the Celestial King made his move, Cao Ya and Meng Tianzheng were completely unable to stop him and were about to be crushed to death!

“At that time, I will take action and keep those three occupied.” The king spoke, seemingly aware of Cao Ya and the one-armed old man’s worries. He smiled and continued, “Don’t worry, I will use the Dao traces on the Primordial Emperor’s Pass. Those fellow Daoists, though they have gone far away, are still with us.”

After speaking, he looked sad and somewhat downcast.

"Furthermore, I can guide the power of the Heavenly Abyss to a certain extent, which will make the Three Kings hesitant and dare not act recklessly," the King said, looking at Cao Ya.

"Don't worry, I will definitely stop the immortals from the other realm! Even if there are many of them... the Grand Elder is also here. The two of us can face several times more immortals together!" Cao Ya said in a deep voice. He was not only confident in himself, but also in Meng Tianzheng.

Looking at the few elderly, children, and the sick and disabled people inside the Primordial Imperial Pass, Cao Ya said, "The future battles in this place belong to the Immortal Kings. They are not yet experts in the Immortal Path. Staying here will be dangerous for them."

"Especially the children, who have not yet grown up and seen the magnificence of the world and the beauty of the mountains and rivers."

"Why don't I take them back to the Imperial Pass? Those who are qualified above the Heavenly God Realm can stay and participate in the World War!"

"Those who are weaker will be sent back to their homeland."

The one-armed old man's heart stirred. He looked at the king with expectation and a hint of pleading in his eyes.

The king, unable to bear it any longer, sighed, "It's all our incompetence that has dragged them down."

"I'm counting on you. Please arrange accommodation for them. As for the various cultivation resources that they need, don't worry about them. Let them strive for and fight for them on their own."

The king finally agreed, though he himself wasn't very confident that he could hold off the three kings in this great battle.

If they are defeated, and the three kings shatter the original imperial pass... are they really going to let these old people and children become cannon fodder?!

If you're really that dedicated, you might as well go to the new Imperial Pass and participate in another war.

"Hmm." Cao Ya nodded. As a World Dao Ancestor, he had this much ability. At worst, he could ask Meng Tianzheng to set aside a region for the elderly, children, sick and disabled people of the Primordial Imperial Pass, given the size of the Heavenly God Academy. That wouldn't be a problem.

However, when the one-armed old man went to inform everyone, the disabled elderly, women and children were unwilling to leave. They only wanted to send the children away, and a group of children even shouted that they wanted to live and die with the original Emperor Guan!

They've lived here for generations; what's the point of going to that new imperial pass? There's no need to return to their ancestral homeland. (Bracelet)

The one-armed old man was angry, but seeing the people's stubborn faces, he felt a pang of sadness.

The people of the original Imperial Pass suffered a tragic fate. Some of the human kings who were once crowned kings, as well as the descendants of kings such as the Dragon King and the Vermilion Bird King, were wiped out during the long period of conflict!

Only a few survived, and there were not many left. Most of them were children, the elderly and women who were injured or disabled. The young and middle-aged men had all died in battle, their blood staining the battlefield.

"Go, this place is destined to be destroyed. Your homeland is not here."

When the king speaks, people have no choice but to accept, though their faces still show defiance.

They decided to go to the new Imperial Pass to participate in the upcoming war between the two worlds; they could not back down or become deserters!

In truth, they knew that with the Immortal King knocking on the gates and a true king ready to fight, their presence would be utterly useless. (Bracelet)

Even if they join forces, they cannot threaten the Celestial King in the slightest!

Finally, the king let the one-armed old man leave as well. The once glorious Primitive Imperial Pass was now guarded only by the king, lonely and desolate, his back view forlorn.

The one-armed old man, along with a group of elderly people, children, and women, left the primitive imperial pass. Looking back, the royal city wall stood alone, lonely and desolate, yet it stood tall and upright, supporting the sky.

Immediately, everyone's eyes reddened, filled with reluctance.

Cao Ya sighed and led everyone back to the Imperial Pass.

"The World Dao Ancestor has returned!" The cultivators cheered. Cao Ya's actions and his astonishing achievements greatly boosted morale!

Later, many cultivators advanced, especially after Meng Tianzheng ascended to immortality. Even with an Immortal King now in charge of the foreign realm, the morale of the troops at Imperial Pass remained unbroken, and their fighting spirit remained fierce!

Even if they are immortal kings, they cannot overcome the obstacle of the Heavenly Abyss. Their opponents are still those human cultivators!

The cultivators were astonished when they discovered the one-armed old man, along with a group of elderly people, women, and children.

who are they?
