The fact that he had obtained the Evil Heavenly Power was known to both the Old Turtle and the True Yang Emperor; it wasn't exactly a secret.

"Alright, I've been asleep for so many years, so I'll accompany you to the Celestial City."

The old turtle shook its body, and a large number of rocks fell off its back and disappeared into the gray sea.

Ning Xiu was immediately curious and couldn't help but ask the Evil Dragon King, "Senior, didn't you say that any race, even celestial beings, would have their minds sealed and their bodies imprisoned if they fell into the Gray Sea? Why is it that this old senior can move freely in the Gray Sea, waking up whenever he wants and acting whenever he wants?"

In response to Ning Xiu's curiosity, the Evil Dragon King explained, "This old tortoise is a naturally occurring species, just like the Tribulus Clan. It was born in this gray sea, and this place is like its home. It can move around freely without any restrictions."

"Such a thing exists?" Ning Xiu was greatly shocked. As the saying goes, there are all sorts of strange things, and even a place like the Gray Sea can give birth to alien species. It is truly astonishing.

Following the old tortoise's lead, the Evil Dragon King flew all the way, and half a month later, the outline of a huge black shadow finally appeared on the sea. Although Ning Xiu had never been there before, he could tell at a glance that it was the Celestial City.

An extremely ancient and weathered aura rushed towards him. Ning Xiu could feel that this aura was somewhat familiar, and it was very similar to the one emanating from Xie Tiantong's huge stone tablet, or rather, they were from the same source.

The area surrounding the Celestial City was entirely a black reef zone, devoid of grass, trees, or even any living creature. Even the Evil Dragon King's body appeared exceptionally small in comparison to the Celestial City.

After landing, Ning Xiu was the first to fly down from behind the Evil Dragon King. Just as the old tortoise had said, the city gates of the Celestial City were now tightly closed.

“This is truly the first time I’ve ever seen this. The gates of Celestial City have never been closed. I wonder what happened. This is really troublesome. We can’t deliver the item you brought to the designated person.” The Evil Dragon King said to Ning Xiu.

Ning Xiu frowned. He had finally managed to come to Tianren City. If he didn't accomplish what the Martial Saint had entrusted to him, it wouldn't be easy for him to come back again.

boom!

Suddenly, a commotion came from inside the Celestial City, and a large amount of starlight shot into the sky, converging into a pillar of starlight that soared straight into the heavens.

Ning Xiu subconsciously looked up and saw several figures within the pillar of starlight. They were fighting over something, and their actions shook the heavens and earth. If the Celestial City hadn't been extraordinary, it wouldn't have remained intact amidst their attacks.

"The Five Elders of Heaven? How come even they've made a move?" The old tortoise, being a resident of Heavenly City, certainly knew more than the Evil Dragon King and Ning Xiu, and immediately saw the situation inside the pillar of light.

The Five Elders of Heaven are the five oldest Heavenly Realm experts currently existing in Heavenly City.

Their path to heaven and man is basically at its final step, with only one step left to reach the end.

Its strength is so great that it can be considered the most powerful in the world.

However, the figures who attacked them at this moment were in no way inferior to the Five Elders of Heaven and Man in terms of strength.

Besides the Celestial City, are there other such powerful individuals in this world?!

"Those great emperors are all waiting to be resurrected. The opening of the Heavenly Gate is already a foregone conclusion. You ancient immortal servants are only left with a wisp of a soul, so why do you still come to obstruct it! What good will it do you if this realm doesn't open!"

“As long as the master doesn’t give the order, you ants will not be allowed to open this Heavenly Gate without permission. You’re overstepping the bounds and acting recklessly. You deserve to die!”

The pillar of starlight shone brightly, quickly enveloping the entire area.

An extremely powerful and terrifying force erupted from the pillar of starlight, soaring straight into the sky and tearing it apart.

The entire Celestial City roared and trembled, and celestial inscription tablets flew into the air, rotating continuously around the pillar of starlight.

Numerous characters emerged from the surface of each Heavenly Dao Stele and merged into the Starlight Pillar, enhancing the brightness of the Starlight Pillar.

Above the sky, in what was originally nothingness, a bronze door slowly emerged. The door was enormous and existed silently in the sky.

Impacted by the pillar of starlight, the bronze door began to sway, showing signs of being opened even slightly.

Streams of colorful light drifted from behind the bronze gate and fell to the ground. Anyone who came into contact with this colorful light was surrounded by immortal energy, as if they might ascend to immortality at any moment.

Ning Xiu stood on the ground, looking up at the battle above him. The battle between the Celestial Realm cultivators was indeed beyond his current ability to intervene.

The aftershocks they cause can even tear apart boundaries. Once you, a cultivator at the Heavenly Dao Realm, are sucked into the rift, you will never be able to get back in this lifetime.

"Ancient Immortal Servant...who is he?" The Evil Dragon King was very puzzled.

He had lived through several eras and had never heard of the existence of this so-called ancient immortal servant.

Ning Xiu, however, had a sudden inspiration and couldn't help but say, "Senior, do you think this ancient immortal is the mysterious great power who opened up the path of heaven and man on the basis of the Great Emperor's Dao? After he made many people become heaven and man, he also sealed that Heavenly Gate, the purpose of which was to prevent the strong in this world from having the opportunity to leave, so that they could only be trapped in this world for their entire lives."

"Now that you mention it, it's quite possible. But I wonder what the purpose is of these ancient immortal servants suddenly appearing in Celestial City. It's too much of a coincidence that they arrived just in time for us," the Evil Dragon King said, puzzled.

"If the sky falls, the tallest person will hold it up. What are you two, who are at the Heavenly Dao Realm, worrying about? Just come and watch the show with me, Old Turtle," the old turtle said disdainfully, lying on the shore.

He didn't know how many years he had lived in the Gray Sea near Celestial City, and he had long since deeply implanted the impression that Celestial City was indestructible in his mind. As long as this world still existed, Celestial City would always exist.

No matter what kind of ancient immortal servants or ancient immortals come, they could never be a match for the combined forces of the Five Elders of Heaven and Man.

Ning Xiu sat cross-legged on the ground, using the power of the Destiny Star to observe the situation inside the Pillar of Starlight more clearly.

The benefits of observing a fight between experts at this level are enormous.

However, at this moment, Ning Xiu's destiny star suddenly underwent a change. Several cracks suddenly appeared on his forehead, and then a small arm emerged from his forehead.

"Hmm!" Ning Xiu's face instantly turned red, and he spat out a mouthful of golden blood. He immediately became extremely listless and weak.

"Why would the Reincarnation Emperor act up at this time!" The Evil Dragon King noticed that Ning Xiu's destiny star had a problem and was immediately shocked.

Chaos, chaos, everything suddenly went completely wrong.

[213] Five Emperors in a Row

Ning Xiu's destiny star kept collapsing, and a large number of fragments fell off from his forehead. Then, a golden figure, about the same size as the destiny star, slowly crawled out from within Ning Xiu's destiny star.

"vomit!"

When his destiny star suddenly suffered this misfortune, Ning Xiu's face was covered in red marks, he couldn't stop spitting blood, and he lay on the ground trembling uncontrollably.

Even someone as powerful as the Heavenly Dao Realm cultivator was as fragile as an ant at this moment, unable to resist the sense of powerlessness emanating from his body.

"How could the Reincarnation Emperor appear at this time? It shouldn't be like this." The Evil Dragon King looked at Ning Xiu, who was on the verge of death, with a complicated expression.

Once the Reincarnation Emperor completes his reincarnation, Ning Xiu's body will be taken over by the Reincarnation Emperor. At that point, all his talents and methods will be wasted on someone else.

"With such a change happening in Celestial City, there wasn't even time to ask them for help in dealing with the Reincarnated Emperor's problem. This is quite troublesome." The Evil Dragon King looked at the huge pillar of starlight within Celestial City.

Above the Celestial City, the colorful light descending from the bronze gate increased, gradually enveloping the entire city. The five elders absorbed this colorful light, and ribbon-like strands began to grow behind them, while wisps of white mist appeared beneath their feet, giving them the faint appearance of becoming immortals.

"Heavenly Gate!"

The golden figure, which had broken free of half its body from Ning Xiu's life star, looked at the bronze door and let out a sound of extreme surprise.

Behind the faintly open bronze door, a world of seven colors could be seen, filled with ethereal music and boundless celestial energy, so much so that staying there for a while felt like one could ascend to immortality.

"A bunch of ants dare to dream of opening the Heavenly Gate and sneaking into the Immortal Realm? Do you even deserve it?! The Immortal Lord has built the Purple Mansion Grotto Heaven in this realm and nurtured medicinal materials. It is already a great favor that each of you has been able to come into contact with the path of cultivation. Now, not only are you not satisfied, but you also want to leave this realm and become an immortal."

As the Heavenly Gate was being opened wider and wider, the ancient immortal servant suddenly roared.

As the figure who spoke tossed his hand, a token flew out of the pillar of starlight, soaring into the sky and crashing into the bronze gate.

The moment the token touched the bronze door, the once brilliant light of the bronze door instantly dimmed and disappeared, then closed again, ceasing the outpouring of its brilliance, and remained silent.

"No!"

Inside the pillar of starlight, the five elders of Celestial City roared in despair.

They had been preparing for far too long to open the Heavenly Gate. The path to ascension in this realm was blocked by something unknown. Upon reaching a certain level, they would encounter a barrier that they could not pass through.

The higher the level of a powerful individual, the clearer they feel this. It's like being bound by an invisible shackle that one can never shake off in their lifetime.

That is why the Five Elders of Celestial City thought of secretly opening the Heavenly Gate and using the immortal energy to forcibly break through the boundary and leave.

However, to their utter surprise, the ancient immortal servants discovered the matter and not only intervened to obstruct them, but also forcibly closed the Heavenly Gate using some unknown means. This was tantamount to shattering the preparations and efforts of the Heavenly City over countless eras, which made the Five Elders of the Heavenly City furious.

"The ancient immortal has long since disappeared, perhaps even abandoning this world. Only you inhuman, ghostly lackeys are still waiting like dogs, unwilling to give up on the ancient immortal's return."

The Reincarnated Emperor laughed loudly. He didn't seem to be very angry about the closure of the bronze gate. Instead, he took the time to observe Ning Xiu, who was lying on the ground vomiting blood.

"What a perfect body! With such a body, I wouldn't even need the Heavenly Gate to break through the barrier and leave." The Reincarnated Emperor exclaimed in surprise.

Throughout countless eras, he had never seen anyone as strange and miraculous as Ning Xiu.

His body was clearly very ordinary, but he possessed immense potential within him, a potential that even the Reincarnation Emperor found unfathomable and could not predict the heights Ning Xiu would reach in the future.

Compared to emperors from other eras, the Reincarnation Emperor's combat strength was not outstanding. However, his ability lay in his ability to reincarnate repeatedly, which gave him exceptional insight, far surpassing that of anyone else.

Having traveled through multiple eras, the Reincarnated Emperor had already figured out some of the specific details regarding the situation in this realm.

Why is it that no one has ever heard of reaching the final end of the Heavenly Path and breaking through the boundary to leave?

That is precisely because the Path of Heaven and Man is a flawed existence and not the true path of cultivation.

The guy who introduced the Path of Heaven and Man never intended for anyone to reach its end, so even if you practice the Path of Heaven and Man until you die, don't even think about breaking through the boundary and leaving.

As for who this being who promoted the Path of Heaven and Man is, the Reincarnated Emperor, having traveled to various parts of this world in various identities throughout countless eras, has also found some clues.

In this frozen, icy land of the world, there exists a cave that has been sealed off for many years and has been forgotten by all.

The Reincarnated Emperor spent several eras breaking open the cave and only understood the situation after reading the books inside.

This world was actually created by an immortal of unknown origin who used extraordinary means to extract fragments from the immortal realm, thus constructing the Purple Mansion Grotto Heaven.

This realm isn't even considered part of the greater world; it exists independently of the universe, with only one entrance and exit, essentially serving as that immortal's backyard.

Every living being in this world is livestock raised by that immortal; they are born in this world and will die in this world.

The reason that immortal built the Purple Mansion Grotto Heaven was so that the people here could cultivate, just like raising livestock, waiting for the cultivators to cultivate on their own, and then using them as materials for alchemy when they matured.

Therefore, under these circumstances, no one can expect to break through the boundary and leave. To that immortal, this situation is like livestock breaking through the pen and escaping.

The end of the Heavenly Path is the final limit of the realm that this world can accommodate at the level of the strongest beings.

The reason why the Great Emperor's Path exists is because the Heavenly Dao does not allow anything to be cut off from all life. Therefore, even a powerful immortal must leave the Great Emperor's Path as a lifeline so that the Heavenly Dao can allow this world to exist.

Therefore, as a Great Emperor, the Reincarnated Great Emperor was not as anxious as the Five Elders of Heaven and Man.

They were destined not to become emperors because they lacked talent, but I am different; I can break through the boundaries and leave at any time.

However, this world is the backyard of the ancient immortals, and no one knows where they will be after breaking through the boundary, except for that heavenly gate.

If one were to fall into the void and encounter tens of thousands of extraterrestrial demons, even a powerful emperor would be unable to cope with such a situation and would only die in resentment, perishing outside the realm.

It was precisely because of this concern that the Reincarnated Emperor hesitated to break through the boundary and leave. However, now that he had discovered Ning Xiu's physique, he became interested again.

If I can use this body to cultivate the Great Emperor's Path, I will be safer dealing with crises outside the boundary after breaking through it.

"Reincarnation Emperor, the Heavenly Gate is closed. If we join forces to kill these ancient immortal servants and reopen the Heavenly Gate, you don't want to be trapped in this realm for the rest of your life, do you? Don't you want to go and see the vast world beyond?"

Seeing that they probably couldn't do anything to those ancient immortal servants for the time being, the Five Elders of Heaven and Man turned their attention to the Reincarnated Emperor.

If we could get the help of this great emperor, it would be much easier to kill these ancient immortal servants.

The earliest generation of Celestials in Celestial City were always aware of the existence of the ancient immortal servants, but they never felt it was time to openly confront them. They secretly continued to plot and develop their schemes, waiting until they were completely confident before taking action to kill the servants, open the Heavenly Gate, go to the Celestial Realm, and seek eternal life.

The existence of the ancient immortals was not the biggest concern for the Five Elders of Heaven and Man. The ancient immortals had disappeared for countless eras, and they were quite certain that they were not currently in this realm.
