"He's dead!" Lin Fei's gaze fixed on the exploding form of Nightmare Emperor, whose body had burst into a cloud of blood mist.

Then, with a fierce sweep, Lin Fei's Eternal Realm engulfed the blood mist—after all, it was the essence of an emperor's flesh, worth as much as many Supreme Demon Emperors. Naturally, Lin Fei would not let it go.

As the essence of Nightmare Emperor's flesh was absorbed into the Eternal Realm, Lin Fei could clearly feel life burgeoning throughout its expanse, plants sprouting up, making the realm gradually teem with vitality.

Of course, to fully pervade the Eternal Realm with life might be challenging, requiring either a lengthy time or a substantial amount of dark demonic life essence.

Thus, Lin Fei turned his attention back to the Yin-Yang Immortal Domain, focusing on the dark demons.

Initially, Lin Fei had come to the Yin-Yang Immortal Domain at its behest and following discussions with the Supremes. He had been invited before, but now things were different.

Even if others asked Lin Fei to leave, he wouldn't. This place had become Lin Fei's blessed land, and the dark demons had become a "catalyst" for birthing life within his Eternal Realm.

However, Lin Fei hesitated. The dispatch of Nightmare Emperor was proof enough that the Dark Demon Domain had taken notice of him and held him in considerable regard.

Therefore, Lin Fei's time was running short. He must continue his raids before the Dark Demon Domain could react further, gathering as much essence as possible. Otherwise, once the Dark Demon Domain learned of Nightmare Emperor's failure—and his death—the retaliation against Lin Fei would be even more furious.

Lin Fei did not delude himself into thinking he could single-handedly eradicate all invading dark demons; that was utterly impossible.

"Whoosh."

In the next moment, Lin Fei's figure vanished, continuing his frenzied rampage...

Days had passed at the headquarters of the Dark Demon Domain, yet there was no word from Nightmare Emperor.

"What's going on? Why hasn't there been any news from Nightmare Emperor?"

"It's been days; hasn't he found Lin Fei yet?"

"It's possible; Lin Fei has been rampaging through the Yin-Yang Immortal Domain, and if luck isn't on our side, he indeed might not be found."

"But consider this possibility: perhaps Nightmare Emperor did find Lin Fei, but he failed—or even worse, he might already be dead..."

A silence fell over everyone.

Dead!

How could Nightmare Emperor possibly be dead? He was a great emperor, a majestic existence second only to the Supremes, far surpassing any ordinary Demon Emperor. Almost no one wanted to entertain the thought of Nightmare Emperor's fall.

The narrative has been stolen; if detected on Amazon, report the infringement.

"Regardless, let's try to contact Nightmare Emperor first."

Attempts were made to reach him, but all were met with silence, deepening the furrows on everyone's brows and sparking a foreboding sense among some of the dark demons.

"Report! Lin Fei is now rampaging almost non-stop within the Yin-Yang Immortal Domain. Our forces in the Dark Demon Domain have suffered heavy losses. Under Lin Fei's relentless assaults, everyone is on edge, and we've lost the capability to continue our offensive, switching instead to defense."

This news startled many dark demons. Lin Fei's relentless rampages had surely exposed his whereabouts. After all, even ordinary dark demons could detect Lin Fei; there was no reason Nightmare Emperor couldn't have.

But still, there was no news or trace of him until now. In fact, many dark demons had already guessed the reason, though it seemed incredible.

After a long pause, one of the dark demon emperors, also a leader at the Divine Realm headquarters of the Dark Demon Domain, spoke in a deep voice: "Considering all the information, it's highly probable that Nightmare Emperor has fallen. Going to the Dark Demon Domain and searching within the Heart of Dark Demons will confirm it. If Nightmare Emperor has indeed fallen, it means there is a powerful being in the Divine Realm capable of slaying an emperor of our Dark Demon Domain.

Such a force is terrifying, not even a Supreme, which is very disadvantageous for us. Even if we send several emperors, we can't guarantee they won't fall as well. Therefore, we must consult the Supremes. It would be best if a Supreme could personally take action to eliminate this threat, otherwise, our offensive operations must be temporarily halted..."

The leading emperor laid out the grim situation facing the Dark Demon Domain. The scenario was highly unfavorable. They had initially been in a great position, seemingly on the verge of overtaking the entire Yin-Yang Immortal Domain, which would have given the dark demons a foothold to establish strongholds.

Then they could continuously deploy forces from the Dark Demon Domain into the Yin-Yang Immortal Domain, using it as a springboard to gradually advance and ultimately take over the entire Divine Realm.

But everything had been going smoothly until Lin Fei, an anomaly, appeared, capable of slaying an emperor and single-handedly throwing the Dark Demon Domain into chaos. Now, they could only defend passively, no longer daring to launch offensive strikes.

...

Within the Chaos, the Dark Demon Lord had transformed into a towering giant, straddling the chaotic void. Every movement he made was imbued with terrifying power. Beside him, numerous other dark demons, only slightly smaller in stature, radiated formidable strength as well.

These were the Supremes of the Dark Demon Domain, each a formidable force second only in status and power to the Master himself.

The Chaos was not exclusive to them; Supremes from other Divine Realms were present as well, seemingly equal in might. At least, neither side could overpower the other.

The mood of the Dark Demon Lord was already sour. He had initially thought the Divine Realm would be easy to conquer, an expectation belied by its deep-rooted strength. Though no Ruler had yet emerged, the number of Supremes was substantial.

Away from the Dark Demon Domain, the Ruler's power was diminished, rendering him no more influential than a slightly stronger Supreme, unable to alter the course of the battle.

"My Lord, we've just received news," reported a Supreme of the Dark Demon Domain. "Our offensive in the Divine Realm has faltered. We've ceased our attacks. No, it's more than just a cessation; we are now on the defensive, and the situation is greatly unfavorable."

"What?" exclaimed the Dark Demon Lord, clearly surprised and incredulous. The demons and emperors of his realm were no easy adversaries. How could they be faltering?

"My Lord, the reports indicate that a Martial Ancestor from the Great Dream Sect named Lin Fei has arrived in the Yin-Yang Immortal Domain to offer support. This Lin Fei is extremely cunning and powerful. Rather than confronting our forces directly, he has been rampaging through the Yin-Yang Immortal Domain, causing our troops to fear for their safety and halt their advance. Moreover, this Lin Fei has even slain Nightmare Emperor.

Now, everyone is unsure just how powerful Lin Fei really is, and naturally, they hesitate to send more emperors against him. Therefore, we can only request that you consider sending a Supreme to assist and potentially eliminate Lin Fei."

The Supremes of the Dark Demon Domain had relayed the information in full to the Dark Demon Lord. Now, the decision on how to proceed was his to make.
