You don't want your secret to be revealed by others, right?

He was a somewhat disheveled man in a green robe.

It was none other than the Main Hall Master!

"Finally, you've allowed your master to come out," the Main Hall Master's lips curled up slightly, glancing at Lin Yue.

"Unless absolutely necessary, of course, I wouldn't waste such a treasure on Master," Lin Yue said.

"Main Hall Master?"

The face of the Golden Feather Demon Saint turned pale in an instant, "Impossible... The World Tree isolates heaven and earth, how could an avatar possibly descend?"

This branch of the World Tree forms its own realm, isolated from heaven and earth; an avatar requires connection through Divine Thought, which allows for remote sensing and control, but once heaven and earth are cut off, naturally it's impossible to create an avatar.

"This... is not an avatar."

Duanmu Yan's face was also serious, speaking slowly, "This is the Martial Arts True Body!"

He stared at the Main Hall Master in disbelief, uttering incredulously, "The Main Hall Master has actually entrusted his Martial Arts True Body within a divine artifact, allowing this disciple to carry it with him?"

The Martial Arts True Body, that is, a separate entity!

It has an independent consciousness, can be treated as a Second Primordial Spirit, and because its memories are almost identical to the original, and can be synchronized at any time, it's unhindered even by the separation of heaven and earth.

This Martial Arts True Body can be regarded as the Main Hall Master himself!

This highest-ranking official of the Ancestor Hall, willing to hide in a fragment of a sword blade and let a disciple carry it around with him, silently accompanying the disciple everywhere?

This was something Duanmu Yan and the Golden Feather Demon Saint could not even dare to contemplate.

The Main Hall Master, a peerless individual on par with the Demon Ancestor, was actually willing to go to such lengths for a disciple of the Great Cultivator level?

This was simply too preposterous!

"Master."

Lin Yue smiled and bowed, "Your unworthy disciple was unable to force more cards out of the Demon Clan, leaving no choice but to ask for Master's intervention."

"No matter, what you've done has already exceeded your teacher's expectations," the Main Hall Master shook his head slightly, looking at his disciple who never failed to surprise him, feeling very satisfied in his heart.

Ever since the original body entrusted the sword fragment containing the Martial Arts True Body to this disciple, he had always been following by the disciple's side, traveling through the human world.

The experiences and growth of his disciple were all witnessed by him, naturally bringing him great comfort.

"From now on, it will trouble Master," Lin Yue bowed.

The Main Hall Master looked indifferently toward Duanmu Yan and the Golden Feather Demon Saint, as well as the five Demon Saints, nodding slightly, "Such a huge gamble, sacrificing five Demon Saints, giving up such a precious avatar and a Semi-Divine Artifact, the Demon Clan really values my disciple..."

An endless oppressive might permeated within the small world formed by the World Tree, causing the Demon Saints' faces to turn pale.

A being who had transcended heaven and earth, a Proving powerhouse who had lived for countless years, from the founding of the Ancestor Hall till now, the position of the Main Hall Master has never changed.

Even most beings with the capacity to transcend and become Saints found it difficult to resist such a figure.

After all... the Supreme Powers capable of Proving and transcending had almost all been rebellious Saints!

Such terrifying power could kill them in just a move or two!

Each of the Demon Saints looked up at the Main Hall Master, their eyes filled with the color of despair, with no intention to resist.

The gap was simply too vast.

"Duanmu brother," the Golden Feather Demon Saint couldn't help but turn to Duanmu Yan, transmitting with Divine Thought, "Didn't you say there was a way to deal with the Main Hall Master? If not now, then when?"

However, Duanmu Yan did not respond, only frowning as he watched the Main Hall Master, seemingly pondering something.

"Demon Clan, since you've come to Great Yong, you might as well not leave."

The Main Hall Master stood in the void, his middle and index fingers pressed together, making a slight motion with his sword finger, immediately unleashing an astonishing Sword Intent.

It goes without saying that the next sword strike will shake the earth, and it would be effortless to slay all the Demon Saints present.

"The Main Hall Master is willing to go to such lengths for a disciple, which is admirable."

Duanmu Yan suddenly spoke with a smile, "Indeed, as the Heavenly Demon Ancestor said, it's only now that Duanmu understands what the Heavenly Demon Ancestor meant."

"Hmm?" The Main Hall Master narrowed his eyes at him.

The smile on Duanmu Yan's lips gradually became relaxed, with a hint of cunning, saying, "Does the Main Hall Master really intend to kill me? Maybe you should look at this first?"

With a flip of his hand, a dark stone pot appeared in his hand.

At these words, the Main Hall Master looked over, and upon seeing it, his expression immediately became grave, "This is..."

Lin Yue also frowned.

What in the world is that?

Even the Master, a Supreme Power who has proved and transcended, is treating it with such caution?

At this moment, the lid of the stone pot had already floated open slightly, revealing a gap from which an incomparably profound and thick darkness could be seen, flowing slowly and silently within the pot like the night.

Upon seeing the contents within the pot, Lin Yue's first impression was that it resembled...

Eternal Night?

Yes, it bore a strong resemblance to the Eternal Night he had experienced in the Illusion Realm.

Lin Yue couldn't help growing more puzzled. How had the Eternal Night been sealed inside a pot? And why was his Master treating it with such seriousness?

"Source of Eternal Night?"

The Main Hall Master spoke in a deep voice, "Did the Heavenly Demon Ancestor specifically refine it as a gift to you?"

"Indeed." Duanmu Yan replied with a smile, "Duanmu stands no chance of resisting in front of the Main Hall Master, but with just a thought from Duanmu, the Source of Eternal Night would erupt entirely within this small world. Would the Main Hall Master care to try?"

The Main Hall Master was silent for a moment, then replied indifferently, "Heavenly Demon Ancestor sure plays a good game of chess. Did he predict that I would act in person..."

Lin Yue was momentarily taken aback upon hearing this.

The Master had once said that the Heavenly Demon Ancestor would surely be suspicious of him, a Prince, showing then his insight into the Heavenly Demon Ancestor.

Now it seemed, did the Heavenly Demon Ancestor understand the Master just as well?

At this moment, he truly recalled the secret legend of the origins of the Demon Clan and suddenly had some understanding of who his Master was.

But... what was the purpose of this Source of Eternal Night?

"Master," Lin Yue immediately sent a Divine Thought Transmission, "what exactly is happening? What is that inside the stone pot?"

"That is the Source of Eternal Night."

The Main Hall Master replied via Divine Thought Transmission, "The final step in the Demonization Cultivation Method is the devouring of the Power of Eternal Night. And the Heavenly Demon Ancestor's most adept technique is refining and improving the Power of Eternal Night to form a source. When the Source of Eternal Night erupts, all nearby members of the Human Clan who have practiced the Demonization Cultivation Method will instantly transform into members of the Demon Clan."

Lin Yue recalled what the director of the Divine Pivot Institute had said about the origins of the Demon Clan, and indeed, this point had been mentioned.

If his Master really was the person he suspected, encountering the Source of Eternal Night would likely result in transformation into a member of the Demon Clan...

"The Master must not be contaminated by a hint of the Source of Eternal Night. Once the Source of Eternal Night erupts, I must disperse this avatar."

The Main Hall Master conveyed through Divine Thought Transmission, "I wanted to help you, but now it seems unnecessary."

"Master..."

Lin Yue was about to say something when he suddenly heard the Main Hall Master sharply exclaim, "It's here!"

In an instant, Duanmu Yan revealed a strange smile as the lid on the stone pot containing the Source of Eternal Night abruptly flung open completely.

At that moment, it was as if a purely dark sun burst forth from within the stone pot, spreading endless darkness wildly, as if the proud sun in the sky had been thoroughly devoured, and profound nightfall descended in its wake.

In the blink of an eye, Eternal Night had arrived.

"Alas..."

The Main Hall Master let out a soft sigh, as this Martial Arts True Body dispersed into nothing.

The terrifying presence of a supreme power who had proven and transcended vanished without a trace.

"Ha ha ha..."

Within the madly spreading Eternal Night, Duanmu Yan couldn't help but burst out into loud laughter, shouting wildly, "As expected, just as I suspected... The Main Hall Master is indeed one of the brothers who created the Beast Transformation Cultivation Method among the disciples of the Human Ancestor during Ancient Times... Qi!"

Compared to the shock of other Demon Saints, Lin Yue had anticipated this, but he still furrowed his brow.

Qi and Tian, the gifted disciples of the Human Ancestor, were the founders of the Demonization Cultivation Method that gave rise to the Demon Clan.

However, Tian became the first member of the Demon Clan, the Ancestor of the Demon Clan.

And Qi became the Main Hall Master of the Ancestor Hall.

But being a founder, Qi must also have practiced the Beast Transformation Cultivation Method, and if contaminated with the Source of Eternal Night, would naturally transform into a member of the Demon Clan.

Still...

He hadn't expected that even at the Master's high level of Cultivation Realm, he would still be unable to resist?

What exactly is this so-called Eternal Night?
