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

The Infinite Blade Intent had transformed into a river of starlight that swept through with ferocity. Duanmu Yan immediately became a dream-like illusion, and under the mad onslaught of the star river, the illusion shattered into fragments.

Though the illusion attempted to reassemble, it barely formed a shape before being torn apart by the star river once more.

"Dream Undying Body?"

Lin Yue's face was expressionless, unconcerned, as he continued to suppress with the Heaven Suppressing Treasure Mirror, simultaneously slashing continuously, shattering Duanmu Yan's Dream Undying Body time and again.

The Dream Undying Body indeed had extraordinary survivability, but it also had a significant flaw.

—In its Dream Undying Body form, it was as insubstantial as a fleeting thought, but its resistance was very weak, able only to draw weak enemies into its dream.

But Lin Yue's Dao Heart had long transformed into a Saint Heart, and after understanding the prototype of the Ultimate Path, he sensed an advancement in his Dao Heart.

The Ultimate Path was not only immensely powerful but a perfect path. Even in its preliminary form, it subtly surpassed the strength of other paths after Harmonization, among those most defying the heavens.

The influence of Duanmu Yan's dream was of no effect to him.

Under the binding of the Heaven Suppressing Treasure Mirror, if Duanmu Yan did not transform into the Dream Undying Body, he would be directly cut down by the Divine Artifact Battle Saber. Even as Dream Undying Body, he could temporarily save his life but could not break the bindings and thus faced inevitable death.

Despite possessing the Dream Undying Body, Duanmu Yan's aura continued to weaken.

"It will probably take dozens to even a hundred slashes to utterly annihilate his vitality," Lin Yue thought as he wielded his saber, "Though the Ultimate Path is supreme, accommodating all, I grasp but a nascent form. Chaos nurtures all possibilities, yet needs my guidance to manifest."

He understood the Sun Chasing Path, thus deriving the art of traversing the Void proficiently on the basis of the Ultimate Path, reaching unimaginable levels.

Heavenly Tribulation Path and Formless Path followed the same reasoning.

But he never studied paths related to the mind, hence could scarcely target the Dream Undying Body effectively, only relying on the extinction ability derived from the Ultimate Path to forcibly annihilate the opponent's undying form.

But, it just took a bit more time, nothing more.

"Your Highness, Your Highness! Can we talk?"

Duanmu Yan's pleading voice came from amidst the ever-shattering illusion.

Lin Yue ignored him entirely, continuing his barrage of slashes.

"Your Highness, don't you wish to save that Baili Fengzhi?"

Duanmu Yan's strained voice rang out, "That Baili Fengzhi forced a Harmonization; even if you use the Great Wish Fruit to retain a sliver of her Divine Soul, she would become a cripple, and won't live many years. But I have a way to save her!"

Lin Yue's saber continued its relentless barrage, without the slightest trace of hesitation.

It was meaningless.

Duanmu Yan's words were merely a bid to save his own life, but Lin Yue would not spare him. Duanmu Yan understood this as well; even if Lin Yue agreed, Duanmu Yan would not believe it.

Ultimately, it was just an attempt to find an opportunity to escape.

As for helping Baili Fengzhi recover...

He had other plans.

"Boom! Boom! Boom!"

The destructive slash of the starlight river continuously swept through, rapidly weakening Duanmu Yan's life aura.

"Your Highness, it's all true! Your Highness? Your Highness!"

"No…Dream Demon Ancestor!"

"Spare me! I can't die! There is much yet I must do, I have not witnessed the fall of Great Yong! I cannot..."

"Haha...kill me then!"

"Where is the Demon God hidden in Great Yong? Save me!"

"If you kill me today, you too will face the same fate one day! One day, the Crown Prince will surely kill you!"

"In the end, it all comes to nothing, hahaha..."

With the frantic, despairing cries of Duanmu Yan gradually diminishing into madness, his aura weakened to the extreme.

His body was destroyed, leaving only the Primordial Spirit, akin to a candle about to extinguish.

Lin Yue abruptly withdrew the Divine Artifact Battle Saber, flipping his hand to retrieve a Green Gourd, activating this supreme Spiritual Treasure specifically for sealing the Primordial Spirit.

"Buzz..."

An invisible pull immediately acted on Duanmu Yan's weakened Primordial Spirit, attempting to suck it into the gourd.

"Hahahaha..."

Duanmu Yan's Primordial Spirit erupted in radiant light, the entire Primordial Spirit transforming into a dazzling ball of light exploding, instantly dispersing the darkness over a hundred-mile radius, like a blazing sun reappearing.

A shadowy glow flowed across Lin Yue's body surface, as he retreated slightly for hundreds of feet, unaffected.

And Duanmu Yan, only scattered motes of light, dispersed without a trace in the darkness.

Thus ended.

"It's over..."

Lin Yue stared at the site of Duanmu Yan's demise, feeling something indiscernible in his heart.

At this moment, his Dao Heart experienced some peculiar changes.

After the Dao Heart transformed into a Saint Heart, for the Dao Heart to make further progress, aside from breakthroughs in the path's realm, it primarily hinged upon realizing the grand obsession and great aspiration that the Dao Heart relied upon.

Even if it could not be truly realized, just moving toward the goal and making significant progress could also allow the Dao Heart to transform.

"The threat of the Demon Clan against me has greatly diminished," Lin Yue stood suspended under the Eternal Night Sky, feeling an indescribable emotion.

Since his rise to prominence, he had been enduring the Demon Clan's threat for years. Even in Di Hong City, he would face assassination attempts, needing to carefully conceal his identity when journeying through the Human World. The Demon Clan's endless tactics made survival a struggle; fortunately, with aid from all sides, he managed to avert disaster.

To him, the threat of the Demon Clan was a series of immense cages.

Until today, mastering the Ultimate Path's nascent form had transformed his power tremendously, and slaying Duanmu Yan was truly the beginning of shedding the Demon Clan's threat.
