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

"You, a Saint-level practitioner, if you were to flank us and launch a surprise attack on us, what then?"

Duanmu Yan said coldly, "If you wish to survive, there's only one way out for you: to join our Demon Clan right now. If you become a being that Great Yong can no longer tolerate, then naturally, we'll trust you."

As he spoke, he turned over his hand and took out a jade bottle, inside of which could be seen the flesh and blood of mutant beasts thoroughly mixed with a large quantity of fresh blood.

"If you don't know the Demonization Cultivation Method, this old one can teach it to you right now." Duanmu Yan watched the Immortal True Lord and said, "This is almost the best-quality demon blood I have on me. You'll have to make your own choice."

The Immortal True Lord's face turned ashen as he asked, "Is it the blood of a Demon God?"

Although the Demonization Cultivation Method was a forbidden text, as a Saint-level practitioner on the Demon Path, he had already considered his escape routes, and having intentionally collected this knowledge, he was naturally aware.

The Demon Clan had also deliberately spread the revised Demonization Cultivation Method in Great Yong.

Thus, he knew that the current Demonization Cultivation Method, although much improved, was still essentially the Beast Transformation Cultivation Method at its core.

It required the blood of the Demon Clan and a large amount of mutant beast flesh and blood from the corresponding bloodline.

The key was the blood of the Demon Clan.

The most common was the blood of a Demon King, which was practically useless to a Saint-level practitioner and couldn't even cause a Saint-level practitioner of the Human Clan to transform into a member of the Demon Clan.

Next was the blood of a Demon Saint, which could transform a Saint-level existence of the Human Clan into a Demon Saint, but they must also devour a large amount of mutant beast flesh and blood from the same source bloodline.

However, even the blood of a Demon Saint was just passable; it didn't significantly enhance the talents of a Saint-level practitioner.

A step above was the blood of a Demon God, which greatly elevated the talents of a Saint-level practitioner, with effects akin to rebirth!

Even then, there was the best blood of the original Demon Ancestors!

The Immortal True Lord did not dare to imagine having the Blood of the Ancestor, but if it were the blood of a Demon God, he would be content. Perhaps he could then grasp a new path and merge it to create the Heavenly Reversal Path?

"This is the blood of a Demon Saint."

Duanmu Yan said indifferently, "The Shadow Path you wield harmonizes quite well with this blood of a Demon Saint and a Dark Flame Beast of the same bloodline origin. It's already considered the best for you."

He sneered inwardly.

How precious was the blood of a Demon God?

An ordinary Saint-level practitioner of the Human Clan, if it were normal times, would first need to establish a Big Merit in Great Yong, enter Eternal Night to reach the heartlands of the Demon Country, and then queue up and wait, perhaps to receive the blood of a Demon God.

Like the Divine Lord Yan Yue, even as a Heavenly Saint-level practitioner and even with the connection to the Prison Demon God, he still had to wait quite a while.

Duanmu Yan had received the blood of the Dream Demon Ancestor and merged with the bloodline of a Demon Ancestor because he was seen as an unpredictable entity, and his role in Great Yong was deemed unique.

Yet under such hasty circumstances, for him to offer the somewhat suitable blood of a Demon Saint indicated he was already being considerate.

"The bloodline of a Demon Saint?" The Immortal True Lord found it hard to accept.

Once he underwent demonization, there would only be the path of betraying the Human Clan left for him—it was a natural opposition of life and a racial conflict.

Even... it was rumored that Eternal Night had faction divisions among all beings.

The Demon Clan were the favored children of Eternal Night.

While the Human Clan stood in opposition to Eternal Night, they were natural enemies.

Once demonized, the Demon Clan's instincts would see the Human Clan as food, and there might even be an invisible force of fate pushing them.

The stronger the being, the more this was true.

To make him betray the Human Clan and flee to live with the Demon Clan in Eternal Night, all for just the bloodline of a Demon Saint?

The Immortal True Lord naturally found it difficult to accept.

"You have no other choice."

Duanmu Yan sent a chilling telepathic message: "If it weren't for the fact that you are a Saint-level existence and somewhat useful, this old one would have killed you right now."

The Immortal True Lord took a deep breath and could only stretch out his hand to receive the jade bottle containing the blood of the Demon Saint and the flesh and blood of the mutant beasts.

At this point, in order to survive, he would do anything, and naturally, he would be willing to do this as well.

"But to fully transform into a member of the Demon Clan, don't I need the Power of Eternal Night?" the Immortal True Lord inquired.

The Demonization Cultivation Method only allowed one to undergo beast transmutation, much like when the Ancient Race first devised the Beast Transformation Cultivation Method.

True demonization required absorption of the Power of Eternal Night just like a mutant beast.

"Just begin the Demonization Cultivation Method," Duanmu Yan said flatly. "As for the Power of Eternal Night? It will be available soon."

The Immortal True Lord was taken aback. This was Great Yong, where Eternal Night had been thoroughly dispelled—how could there be the Power of Eternal Night?

However, Duanmu Yan clearly didn't want to explain, and he didn't ask further. Immediately, he began operating the Demonization Cultivation Method, absorbing the blood of the Demon Saint and the flesh and blood of the mutant beasts.

Gradually, as the blood of the Demon Saint was slowly absorbed, the flesh and blood of the mutant beasts continuously flowed out of the jade bottle, attaching to the surface of his body, slowly forming a cocoon of flesh and blood similar to an eggshell, like a placenta nurturing life...

Duanmu Yan no longer paid attention and instead turned to look at Lin Yue.

"Seventeenth Prince."

Duanmu Yan said indifferently, "The Undying True Monarch you rely on has already become a part of my Demon Clan, Your Highness. Do you still wish to resist?"

Five Demon Saints also rose into the air, surrounding Lin Yue from all sides and above, the colossal pressure of the Demon Saints relentlessly diffusing.

Lin Yue regarded the demonized flesh and blood elemental embryo with a thoughtful look.

It was his first time witnessing the scene of demonization.

"Your Highness is interested in demonization?" Duanmu Yan was in no hurry, and even seemed to be waiting for something.

"Slightly interested," Lin Yue was also buying time and said, "I'm curious, what is your current state? I heard that after demonization, the instinct is to consume the Human Clan for sustenance. But with the heart and mind of a being who has become Saint, can you not resist this instinct?"

"Demonization naturally changes both body and mind."

Duanmu Yan said indifferently, "Of course instincts can be resisted, but when your cognitions have changed, when you no longer have any recognition of the Human Clan, would you still forcibly endure the instinct? Besides... this is fate, the fate brought by Eternal Night."

"Fate?" Lin Yue pondered.

He could somewhat understand the point about cognition.

As for the ethereal concept of fate, that was harder to comprehend.

"If I were to become part of the Demon Clan, what level of bloodline would I have?" Lin Yue suddenly asked.

Upon hearing this, Duanmu Yan couldn't help but reveal a hint of joy and immediately said, "If Your Highness is willing, naturally it would be the Ancestor Bloodline!"

The flesh and blood elemental embryo nearby stirred, the Undying True Monarch within it having clearly heard as well.

"Ancestor Bloodline?"

Lin Yue's heart stirred upon hearing these words.

The Original Divine Blood he needed had already been roughly pinpointed thanks to information obtained from the Second Prince.

But Original Divine Blood had a will of its own. To attract the appearance of Original Divine Blood, a lure was necessary.

This lure... either the blood of an Ancient Divine Beast at the level of Divine Beast, or the blood of a Demon God that had contained Divine Power, or it could be the Source Blood of the Demon Clan Ancestor.

Perhaps there was an opportunity to obtain the Ancestor Source Blood this time?

Lin Yue without a change in expression, made an indirect inquiry, "That truly is a generous offer... May I ask which Ancestor's bloodline it is?"

"Naturally, it is the bloodline of the most invincible Heavenly Demon Ancestor."

Duanmu Yan said with a smile, "The Heavenly Demon Ancestor regards Your Highness very highly, and has specially extracted a drop of Original Blood for Your Highness. You should realize the sincerity of my Demon Clan now, shouldn't you?"

Indeed, it was the Ancestor Source Blood... Lin Yue mused for a long while, then said, "Alright, I agree."

"Good, good, good."

Duanmu Yan couldn't help but be overjoyed, "Your Highness truly knows the ways of the world. Rest assured, Your Highness, your status in our Demon Clan will not be inferior to that in the Human Clan."

Lin Yue slightly raised an eyebrow and said, "However, I do not wish to go to Eternal Night for the time being."

"Not going to Eternal Night?" Duanmu Yan asked in confusion.

"I have just mastered a Heavenly Reversal Path."

Lin Yue said, "My goal is to master several Heavenly Reversal Paths, to blend them as much as possible, and to approach the legendary Ultimate as close as I can. It is said that the Crown Prince and Second Prince did so, and I admit I am not as gifted as they are. But if I receive the assistance of the Demon Clan Ancestor Bloodline, I should have a greater chance of reaching that step."

"Ultimate?" Duanmu Yan drew in a breath of cold air.

He had also heard that in Ancient Times, the Ultimate Path did exist.

It was the ultimate of all paths.

But no matter how exceptional one's talents were, without ultimate guidance, as high as one's comprehension could be, as great as one's circumstances could be, they could only get close at most.

Mastering a part of Chaos, they might already display a semblance of the Ultimate Path.

It was rumored that both the Crown Prince and Second Prince were like this, and among the Demon Clan Ancestors, there were existences as terrifying as that, for instance, the Heavenly Demon Ancestor was such an existence.

Who would have thought... This Seventeenth Prince also held such ambition?

However, it was said that his previous life, the Prison Demon God, was also like this. After reincarnating as a prince, it was natural to instinctively pursue closeness to the Ultimate.

"Your Highness pursuing such ambition is worthy of my utmost admiration," Duanmu stated.

Duanmu Yan immediately said with a smile, "Since that is the case, it is very simple. Your Highness need not wait any longer. Please proceed to Harmonization now."

"What?" Lin Yue narrowed his eyes slightly.
