"I'm counting on you." The Black Emperor stood up and bowed respectfully.

Despite his carefree and irreverent attitude, the Black Emperor was extremely cautious when it came to the resurrection of the Great Emperor Wushi.

Furthermore, from the ancient times to the present, having experienced so many eras of birth and death, the Black Emperor, with his eccentric, rather wicked, and mischievous personality, has also become a senior expert and a prehistoric powerhouse. With too many old friends gone and his homeland destroyed several times, after countless separations and deaths, how could the Black Emperor not become more composed?

Even if his true nature remains unchanged, he only shows it in front of old friends. He feels he cannot disgrace the ancient times in front of countless generations of younger generations!

Cao Ya's eyes flickered, and he felt quite sad. According to Cao Ya's memories in [Covering the Sky], after entering the Immortal Realm, the Black Emperor was still as lawless as ever, full of bad intentions, playing tricks on all kinds of characters, and never calming down. He was always hanging out with Duan De, Hua Hua, and others, which was a real headache!

Only in front of the Great Emperor Wushi and the Great Emperor Ruthless would these people behave obediently and dare not do anything.

Even Ye Fan and his group couldn't control Hei Huang and Duan De, often leading to a situation that was both laughable and absurd.

The Black Emperor of my memory, compared to the black behemoth before me, exudes a completely different aura. It is no longer unrestrained, but rather so composed. And when I think of the major events of the past, how can I not be filled with emotion?

"Alas, if I cannot become a Seven-Star Immortal Emperor, I, the author of 'Covering the Sky,' may perish even billions of years later when darkness revives. Even if I become an Immortal Emperor, I will still find it difficult to stop the bizarre cataclysmic destruction!"

Cao Ya sighed inwardly. Because they belonged to a parallel universe, whether it was him in the "Perfect World" or Cao Ya in "Covering the Sky," sooner or later, they would have to face the strange and confront the dark cultivators to protect the Boundary Sea and all the heavens!

But does someone with only the combat power of an ordinary Immortal King have this ability?

"So what if I don't have the ability? Should I just surrender and admit defeat? Either way, I'll just die!" Cao Ya muttered to himself, his will resolute.

Moreover, the dark threats of those two worlds are still quite distant, with their revival time billions of years away. There are still long years for those two Cao Ya to cultivate and receive more help from the system space! They have the potential to become Quasi-Immortal Emperors, or even Supreme Immortal Emperors of the Seven Stars!

In contrast, he himself is in the most dangerous situation. Darkness oppresses all the heavens and is about to destroy the world and reap the harvest of this era!

"Any kind of divine medicine or elixir will do, but if there is the Three Lives Emperor Medicine, that would be the best!" the Black Emperor said.

"..." Chu Feng was helpless. The Three Lives Emperor Medicine had only appeared in a very few ancient books. In the nearly ten million years of the Heavenly Emperor Era, the vast Yang Realm had never had such an Emperor Medicine!

“I will keep an eye on it, but I’m afraid things won’t be peaceful in the mortal realm in the future…” Cao Ya nodded, then suddenly smiled.

"Striving for unification? You're interested in that too?" The Black Emperor was surprised, not realizing that Cao Ya was an evolved being who desired the position of Heavenly Emperor!

"I must remind you, that is not a simple task. To become the Heavenly Emperor is not something that can be done simply by having enough power. It also requires a broad mind, great ambition, and, more importantly, the patience and ability to govern the world!"

Then, the Black Emperor warned that without the relevant mindset, even if one's strength meets the standard, one will not be convinced by all races and be revered as the "Heavenly Emperor." In this case, one will naturally not receive the blessing of the myriad paths of the mortal world, and a large part of one's immense fortune will be lost!

"The burden of being the Heavenly Emperor is too heavy. I currently have neither the power nor the mind to do so."

Cao Ya shook his head and said in a low voice, "Among the more than twenty people I killed in the outer realms before, there were many spies from the Soul River and traitors from the mortal world. I'm worried that the strange Soul River may have been alarmed and can't sit still anymore!"

Black Emperor's expression instantly turned serious. Since it involved strange forces, he could not afford to be careless in the slightest!

"Back then, we followed the Three Heavenly Emperors to fight against the Soul River and the Dark Cultivator. We achieved great success and killed many people. However, due to the participation of the Ancient Underworld, the Heavenly Emperor's Burial Pit, the Four Extremes Floating Soil, and other strange forces, strange Immortal Emperors and Quasi-Immortal Emperors appeared, outnumbering us several times over, and we had no choice but to retreat."

"Furthermore, the strongest black blood is flowing from the depths of the Edo Plateau, threatening to corrupt the heavens. The Great Emperor Wushi left behind to cover their retreat..."

"It was in that battle that the Great Emperor Wushi died from exhaustion, and the Wushi Bell shattered into pieces. In the end, the broken bell carried the emperor's corpse back to the heavens..."

As Black Emperor spoke, his face was filled with sorrow, and his mood was extremely low.

The Great Emperor Wushi has perished, and the Heavenly Emperor Ye and the Ruthless Great Emperor have disappeared without a trace. The Holy Prince, Ji Zi, Dao Yi, Little Divine Silkworm, and others have also been almost completely killed or wounded. They fought fiercely against the strange creatures, but finally their blood, energy, and soul withered away and they passed away.

Besides himself, the Black Emperor knew that only a very few people, such as Duan De and Hua Hua, had survived, but they were also seriously injured. The chilling mist and cold air had penetrated deep into their souls, and even after millions of years of recuperation, they had not fully recovered.

Chu Feng looked slightly dazed. Three Heavenly Emperors led their troops, and numerous Quasi-Immortal Emperors, Immortal Kings, and True Immortals participated in the battle. The battle was bizarre and affected all the heavens. What kind of war was that?

In the dim light, he seemed to see the myriad worlds of stars falling, the colorful immortal energy, and the endless chaotic mist surging through the universe. Every collision could shatter heaven and earth and reshape the universe!

"The strange ancestral land, beyond the Evil Earth Plateau, also has considerable territory among the heavens, connecting all realms. If they so desire, they can launch an attack on any realm!"

The Black Emperor whispered, "The River of Souls, the Heavenly Emperor's Burial Pit, the Ancient Underworld, the Four Extremes Floating Soil—which of these places doesn't have a supreme being from all the heavens overseeing it? It's perfectly normal for one or two Immortal Emperors at the end of the road to secretly emerge!"

"You've cleansed out a bunch of Soul River spies from the True Immortal Realm and traitors who defected to them. It's quite possible that the Soul River's leader has awakened and will launch a probing attack on the mortal realm!" The Black Emperor glanced at the broken bell beside him and the imperial corpse that seemed to be sleeping against the broken bell, his eyes filled with murderous intent!

Even if his strength has declined and he is no longer at the peak of his Quasi-Immortal Emperor status, and he is unable to contend with the supreme beings of the heavens, killing a bunch of Dark Immortal Kings and True Immortals would still be a great pleasure and a way to weaken the Soul River!

"Even though I'm much weaker, dealing with a Celestial King is still no problem," the Black Emperor muttered to himself.

Chu Feng glanced sideways. A Quasi-Immortal Emperor? Was he really that terrifying? Even with a declining cultivation level and still recovering from serious injuries, he could easily kill a powerful Immortal King?!

"If even a Quasi-Immortal Emperor is this terrifying, how monstrous must the Immortal Emperors above them be!" Chu Feng exclaimed in amazement.

"There's nothing a Celestial Emperor can't do, whether you can imagine it or not!" the Black Emperor sneered. At this level, there was no longer any possibility of rebellion. No matter how strong a Quasi-Celestial Emperor was, they were no match for a Celestial Emperor!

Even though the Desolate Heavenly Emperor had just entered the Immortal Emperor realm and killed the Corpse Immortal Emperor, the prerequisite was that Shi Hao had already attained the Immortal Emperor status!

Cao Ya also yearned for such a powerful being, who could interfere with the primordial chaos, create the world, disrupt time and space, and overturn cause and effect. Such a being was nothing more than a trivial matter.

However, even though he entered the system space and had so many selves, including some living in the seven-star universe, he still lacked confidence in achieving the seven-star level and becoming a cosmic giant!

The Immortal Emperor of [Sacred Ruins], the Other Shore One of [Peerless Sovereign], the Primordial Controller of [Stellar Transformation] and [Panlong], the Creator of [Immortal Gourd], the Primordial Saint of [Primordial Era], the Controller of the Chaotic Universe of [Desolate Era]...

They are all the most powerful masters in their respective universes, overlooking countless realms and billions of eras, eternally immortal!

For example, the Immortal Emperors of this world are incredibly powerful and difficult to kill. Even if they were to perish in a battle between equals, as long as there is still a trace of them remaining, they would still have a chance to revive and return, even if this process might require billions of years of accumulation!

"If any strange cultivators invade, notify me immediately! I will definitely kill those bastards and avenge them!" Black Emperor said, filled with extreme hatred for the strange and determined to fight them to the death.

Afterwards, Cao Ya left the empty world controlled by the Black Emperor, and Chu Feng also left.

According to him, now that he has become the Twin Kings, he should seek trouble with the Supreme Heavenly Venerable Taiwu and seize the opportunity to kill this great enemy!

As a Celestial Venerable of the Martial Maniac lineage, even if Taiwu Celestial Venerable is not Heng Celestial Venerable or Da Celestial Venerable, he must still be a Supreme Celestial Venerable!

But in front of King Heng, ordinary Heavenly Venerables are no match at all. He can easily defeat those of higher levels. Even top Heavenly Venerables can be fought by King Heng. Only after they have fought can we know who is stronger and who is weaker!

Moreover, Chu Feng possesses the Dao Fruit of the Double Eternal King, so even if a Great Heavenly Venerable were to emerge, he would be fully confident in his ability to contend with him!

"Senior Cao Ya, don't worry. The Martial Madman has been killed by you and Master No. 9. With the fall of the immortal experts of this lineage, even if there are still Hunyuan Realm experts, I can still protect my life if I'm careful."

Chu Feng spoke with considerable confidence, leaning against the stone jar. He dared to deceive even immortal experts, let alone human cultivators.

"Besides, it seems that Taiwu Tianzun only has one master, a powerful expert at the Hunyuan Realm. That woman can't possibly keep watching Taiwu Tianzun without cultivating herself or doing her own thing, can she?"

"The Martial Madman is gone. The consequences are severe. Even powerful cultivators at the Primordial Realm are facing a major headache and the possibility of danger. Where would they have the extra time to care about the Supreme Martial Celestial Venerable?!"

"At least on the surface, no one is mainly targeting Heavenly Venerables to kill; they're all aiming at Primordial Chaos Realm cultivators!"

Chu Feng's eyes shone with divine light, his face grim. He wanted Taiwu Tianzun to taste what pain was!

In the past, in the Lesser Underworld, he fought with all his might, but he couldn't even defeat the avatar of Taiwu Tianzun. Now, however, he is confident that he can beat Taiwu Tianzun's true form into a dead dog!

"So many blood debts, Taiwu Tianzun, you won't escape!" Chu Feng whispered, then walked away with a murderous aura.

Cao Ya only gave a few words of advice. Because of his intervention, Chu Feng's strength improved much faster than in the original timeline!

Now that the Martial Madman is dead, Chu Feng is indeed capable of maneuvering among that faction without being instantly killed.

That was Chu Feng's blood feud, and Cao Ya could not possibly do it for him. He also trusted Chu Feng, and even killing the Heavenly Venerable required his help. Chu Feng was probably in trouble even in the Immortal Realm, let alone the King Realm and Emperor Realm later on!

Cao Ya once again walked the mortal world, going in and out of famous mountains and rivers. Occasionally, people would see his figure and think he was a legendary first-class figure, which greatly impressed them!

All kinds of dangers no longer pose any threat to Cao Ya. Even if the prehistoric great mutated and hibernated in dangerous places, it would be no match for Cao Ya at all. If it did not appear, that would be fine, but if it did appear, it would be killed on the spot!

It was obvious that when Cao Ya appeared, all sorts of gods and ghosts lay in wait. They may not have recognized Cao Ya, but they all sensed a deadly threat from him!

It was as if the Celestial King himself could destroy dangerous places and flatten desolate regions, and any prehistoric monster would have to wait to be slaughtered!

In fact, in the mortal realm today, there are only a very few areas that Cao Ya fears and dares not venture into.

With Cao Ya's combat strength, there's nothing to fear about a normal king in slumber, unless it's a giant or above!

However, such beings are extremely rare and few in number, even among those preserved throughout history in the mortal realm.

Of course, it wasn't that Cao Ya intentionally went to dangerous places. It's just that the mortal world is vast, and although the myriad paths are hidden in the void, there are always some special places where parts of the Great Dao will manifest and shake the heavens and earth!

Cao Ya yearns to observe the laws of the Great Dao, understand the path ahead, and use the "Great Sun Tathagata Fist" as a foundation to push the pollen path to the realm of the Kingly Way!

However, during this process, a new and shocking change occurred in the mortal realm!

Boom!

"!" Deep within Yinzhou, a soaring light burst forth, illuminating several nearby states in a dazzling display. The intense energy surged, extremely powerful, causing the heavens and earth to tremble and the sun and moon to shake, as if they were about to fall to the mortal realm!

The people of several states were filled with fear and trembling, feeling as if the end of the world had come and the sky was falling and the earth was collapsing!

"Something terrible has happened!" In countless states and continents of the mortal realm, all beings at the immortal level sensed it, but all wore solemn expressions, and no one could laugh out loud.

That kind of earth-shattering commotion is something even those at the Ultimate Realm would find difficult to create!

Moreover, several years ago, there were unusual movements in Yinzhou. Half of the province collapsed, and black mist and yin energy emerged, sweeping across the vast Yinzhou. The atmosphere was completely out of place with the yang world, and it was very similar to the great underworld recorded in ancient books!

Recalling the myths and legends of the past, everyone realized that this was very likely the place where the underworld and the world of the living were connected. For some reason, it had remained unchanged for hundreds of millions of years, but now it has begun a fierce connection, with energy surging and shaking the world!

"The Yin energy is seeping into the mortal realm. Could it be that the Great Yin Universe is about to fall into this world?"

Many cultivators pondered this, their faces quite grim. If the Yin energy were to run rampant, it would not be good for their cultivation, nor for the cultivation of their descendants!

Ancient texts record that the methods of cultivation in the underworld are completely different from those in the mortal world.

The upheaval in Yinzhou has caused widespread panic throughout the mortal realm. Even with the presence of powerful immortal cultivators from prehistoric times, the situation remains unsettled.

Beneath a precipitous peak, Cao Ya gazed into the direction of Yinzhou, his divine sense spreading out and sensing a massive amount of chilling Yin energy merging into the vast world of Yang!

"Have the Underworld and the Realm of the Living finally connected?" Cao Ya muttered. All the myriad realms, such as the Realm of the Living, the Underworld, the Fallen Immortal Realm, the Misty Star Realm, and the Celestial Realm, have all had glorious and brilliant histories. They once illuminated the heavens and were famous throughout the ages. Unfortunately, some have fallen into ruin, some have perished, and some are just barely surviving and struggling to live out their days.

Unlike the others, he did not share their anxieties. With the strange phenomena nearing their revival and on the verge of destruction, the close connection between all worlds was imperative!

Going to fight against the supernatural alone is no different from suicide.

Only through the united efforts of all the heavens can there be a sliver of hope, a fierce and unpredictable battle, to protect all realms!

"Alas, it is a great pity that no Quasi-Immortal Emperor has yet been born in this era!"

Cao Ya sighed. There may be many kings in the great worlds of the heavens, but most of them are remnants from prehistoric times. There are not many from the new era, let alone newly born quasi-immortal emperors!
