According to the narrative,
The final rebirth of the Ninefold Nirvana Technique would bring a complete transformation, a true rebirth of the cultivator. In the novel, Yang Yun relied on this last transformation to alter his demonic bloodline and become fully human.
After learning the hidden storyline about the outer-realm remnant soul, Yun Jin suspected that Yang Yun had used this transformation not only to convert his demonic bloodline, but also to completely eradicate the remnant soul of the Devourer Demon God.
Even though it was only a remnant soul, it still belonged to the Devourer Demon God. Thus, even with Yang Yun's heaven-shaking cultivation, he had to consume the entire demon race and then transform his bloodline in order to cleanse that lingering fragment once and for all.
This answered one of Yun Jin's lingering doubts—
Why did the male protagonist suddenly decide to become wholly human?
In the book, it was explained that children born of human-demon unions often faced severe bloodline conflicts, with barely one in a hundred surviving. Yang Yun, in order to be with Ye Danxia, supposedly made this desperate choice.
This portrayal painted Yang Yun as a man blinded by love. But would Yang Yun really be that kind of man?
Just think of what happened to Ye Danxia in this lifetime once she had lost her value. That was her end. For someone like Yang Yun, it was impossible for him to make such a radical, self-destructive decision out of love.
The most likely explanation was that the remnant soul had threatened him in some way. So Yang Yun chose the most extreme path instead.
No one, not even that remnant soul, could have anticipated that Yang Yun would go so far as to sacrifice the entire demon race and discard his own demonic bloodline just to shake him off. It could only be said that the remnant soul had run into someone far more ruthless than himself.
Of course—
This was still just speculation.
Yun Jin didn't voice these thoughts. She continued watching the blood demon's memories.
Afterward, Xue Daoren pledged himself to the Demon Sovereign, becoming one of his subordinates.
Unfortunately for him, he was never trusted as an inner confidant. Soon after, the Demon Sovereign planted a secret life-and-death seal upon him and sent him into Canglan Kingdom to develop in secret.
Xue Daoren was of the Illusory Demon clan, a race adept at concealment but weak in battle. This made him well-suited for espionage.
Upon entering human lands, he dared not make any overt moves at first. He hid in the shadows, cautiously building his strength. His so-called Blood Dao Gate was pitifully small, hardly a threat.
Until a few years ago—
Ji Wusi's eyes flickered. He waved his hand, slowing down the playback of the memory.
In the image, Xue Daoren stumbled into an underground pit and, by chance, obtained a strange treasure. It looked like a withered tree root, and from its surface seeped a mysterious liquid.
Through experimentation, even sacrificing some of his own subordinates, he discovered that this liquid could mask all traces of demonic or corrupt energy.
What's more, the tree root continued to produce the liquid endlessly.
With this treasure in hand, his expansion quickened dramatically.
The memory revealed how he spread his influence, infiltrated Canglan Kingdom, and turned its capital into his sect's base of operations.
After skimming past these events, the playback shifted to recent days.
Ji Wusi again slowed the scene.
At first, Xue Daoren bore no grudge against Yun Jin. His focus was simply on subjugating Canglan Kingdom and making it his first stronghold.
But one day, he suddenly froze, then shifted his plans to target Yun Jin.
"Clearly, Xue Daoren received someone's orders," Liu Li said softly.
Ji Wusi sneered. "His master is the Demon Sovereign. Who else could it be? The Demon Sovereign was wounded by Yun Jin and must have resented her deeply, so he had his lackey set this trap for Xiao Jin."
Xue Daoren's exchanges with the Demon Sovereign occurred in his sea of consciousness, inaudible to others, but his behavior left little doubt.
The vision continued.
At a certain point, Ji Wusi slowed the playback to its lowest pace.
One of Xue Daoren's followers asked nervously, "Sect Master, is it wise to act so brazenly now? I heard that the Kunlun Sword Sect's Sword Immortal and experts from other Holy Lands have come to this region. If we move recklessly, the Demon-Slaying Alliance may intervene, and should those top-tier powers get involved, none of us will survive."
Xue Daoren's lips curved in a confident smile. "Rest easy. This time, no one will be able to concern themselves with us."
Yun Jin raised her brows. "So he already knew the Demon-Slaying Alliance wouldn't interfere, and that my Master and the others would be tied down. And who could have given him such confidence, Pavilion Master Lin? Who else but you?"
Lin Xiao's expression darkened.
Inwardly, he cursed Xue Daoren for speaking so much. Outwardly, he remained composed. "He could have said that just to steady his subordinates' hearts. To pin this on me based on such flimsy words is far-fetched."
Yun Jin gave a cold laugh. "Then let's keep watching."
The memory flowed on, showing how Xue Daoren set everything in motion.
Most of this was already known to them.
But from his own perspective, one detail stood out starkly—
The strange behavior of the Yuehua Sect cultivators. When Xue Daoren saw them, he actually sighed in relief. He even edged closer to them, as if they weren't enemies but allies.
Ji Wusi replayed this part several times before sneering in silence.
Lin Xiao narrowed his eyes but held his tongue.
Soon, the final scenes played.
Xue Daoren was decapitated by Yun Jin's sword.
Ji Wusi took out a memory pearl, sealing the vision inside, before turning his gaze on Lin Xiao.
"Pavilion Master Lin. What do you say about the conduct of those five from Yuehua Sect?"
Lin Xiao's tone was steady. "Yuehua Sect is the closest to Canglan Kingdom. They likely heard the disturbance and rushed here intending to save Yun Jin. Misunderstandings arose midway, leading to unfortunate conflict."
"Is that so? Strange, then, that Xue Daoren looked at them as though he'd found salvation." Ji Wusi pressed further.
Lin Xiao sighed. "When one wishes to condemn, charges are never lacking. Sect Master Ji, you have already lost your fairness under Yun Jin's influence."
"Fairness?" Ji Wusi's eyes sharpened. "What favors you is fair, and what condemns you is unfair? Yun Jin, tell me, how many heretics have you slain in Canglan Kingdom?"
Yun Jin answered crisply, "Under Xue Daoren's lead, I destroyed ten bases of the Blood Dao Gate, killing three thousand five hundred and twenty-three of its members. Later, I slew more than fifteen hundred from other heretic sects. And this is only part of what existed within Canglan Kingdom's borders."
Ji Wusi turned back to Lin Xiao. "One Blood Dao Gate has already grown to this scale within human lands. Add to that countless other cults running rampant. And this is only within Canglan Kingdom! What of the rest of this region? How deep does the corruption run there? Likely no better than here.
Tell me, Pavilion Master Lin, how has Qingxiao Pavilion been managing all these years? Have you ever seen heretic forces reach such strength in the other three Holy Lands' territories? If you are truly this incompetent, perhaps it is time you stepped down and gave way to someone who can govern properly!"
