"Does this guy really have a natural Demon Heart?"

"I'm not mistaken!"

"At first, I thought this fellow was like those people from our White Emperor Family who fell victim to the Soul Fusion Technique, which is why he supported the Demon Race so much. But then I thought about it and realized something was off."

"If it were just the Soul Fusion Technique, he couldn't have been named a Demon Seed by the Demon Race; at most, he'd be treated as a vessel... So, I observed him more carefully."

"Only then did I discover that this person actually possesses a natural Demon Heart!"

"Such a person can be described as a cancer within the Human Race, but for the Demon Race, they are a natural Holy Son... Once the Demon Heart is Awakening, and with the full cultivation of the Demon Race, he would definitely become a terrifying Arch-Demon in the future!"

"However, this guy's Demon Heart hasn't truly awakened yet. But hidden within his heart is a very pure strand of Demonic Qi. Likely, a powerhouse of the Demon Race discovered his Demon Heart and has been secretly nourishing it with that Qi."

"So, don't kill him yet!"

"Use him as bait and make a plan; we should be able to trap the Demon Race!"

Li Yun was immediately moved by these words.

If he could really set a trap to ruthlessly slaughter some of the Demon Race, it would be immensely beneficial for both the recovery of the Heavenly Ancient King Mountain's Qi Fortune and the growth of his own Qi Fortune.

Being able to seize Qi Fortune without worrying about causing damage to the Heavenly Ancient Continent—and even gaining benefits—was truly killing two birds with one stone.

The only possible side effect was that after setting the trap to kill the demons, he might completely enrage the Demon Race and become their target.

But was that even an issue?

Judging from Zhao Yunchu's ambush this time, even without the subsequent trap, he was likely already on the Demon Race's blacklist.

Whether he killed more demons or not, the consequences would be the same.

There was simply nothing worth worrying about.

Thus, Li Yun immediately made up his mind.

"Fine. In that case, we'll suppress and seal him first. We'll find a suitable opportunity to throw this guy out to lure the Demon Race, treating it as recycling waste."

"That works!"

Bai Fantian nodded; that was exactly what he meant.

Regardless of whether they trapped the Demon Race later, keeping a person with a natural Demon Heart for now meant there might be a use for him in the future. It was much better than killing him outright.

Immediately.

Li Yun gave Zhao Yunchu a smirk.

"Zhao Yunchu, I've thought about it. You are, after all, the Ninth Princess's only elder brother. I've decided to spare your life, but don't even think about regaining your freedom in this lifetime!"

"For the rest of your life, you will honestly accept being sealed."

As soon as he finished speaking.

Li Yun immediately cast a Divine Ability. This Divine Ability came from the White Emperor Inheritance and was called 【Hundred Sword Profound Seal】, a top-tier Earth-grade Divine Ability.

Its power wasn't great, but it was incredibly potent for sealing and suppression.

With Li Yun's current strength, once he suppressed Zhao Yunchu, there was basically no hope of escape, not to mention the involvement of the Heavenly Ancient King Mountain.

After sealing Zhao Yunchu's cultivation and suppressing him within the Heavenly Ancient King Mountain, it was equivalent to borrowing a portion of the world's Divine Might.

Forget about Zhao Yunchu being unable to escape; it wouldn't even be possible for the Demon Race to find him again.

This fate was quite miserable.

It could be called a fate worse than death.

Facing such an outcome, Zhao Yunchu naturally couldn't accept it. He began to shout curses on the spot, howling hysterically and cursing Li Yun over and over to die a horrible death.

However, Zhao Ziyue was actually quite pleasantly surprised by this result.

Regardless of how miserable this outcome was for Zhao Yunchu, it gave her some peace of mind. At least her brother, Zhao Yunchu, was still alive, right?

A miserable life is better than a good death.

Moreover, being able to save her brother's life without worrying about him coming out to cause trouble again was perfect. How could she ask for anything more?

"Let's go, let's check out that dungeon."

After sealing Zhao Yunchu, Li Yun stowed away the Heavenly Ancient King Mountain. Once again cloaked in shadows, he walked out of the small courtyard and headed boldly toward the dungeon.

Zhao Ziyue and Evil Blade Supreme were brought along by Li Yun's side.

Under the shroud of the shadows, the two of them finally experienced what it meant to be miraculous—entering a place as if no one were there.

The entire palace was filled with patrolling guards.

There were also many Celestial Human Realm retainers.

But even as Li Yun led the two of them past them in broad daylight, they didn't notice a thing.

Even Evil Blade Supreme, who wasn't much of a flatterer, couldn't help but praise: "Li Yun, is this Divine Ability of yours also from the White Emperor Inheritance? It's simply too powerful."

"With this Divine Ability at your side, in this vast world, where can you not go?"

Li Yun was actually quite satisfied with the mental cultivation technique 【Void】. However, as his horizons gradually expanded—having mastered a Quasi-immortal Technique and obtained two Great Emperor Legacies—he didn't dare to be too arrogant.

Because he knew that in this world, there was no such thing as a Divine Ability or method without a flaw.

【Void】 was the same.

The shadow cloak seemed invincible, but in reality, it was just that he hadn't yet encountered someone who could see through the mystery.

If nothing else.

The Space Profound Truth alone would suffice.

If someone could comprehend the supreme Space Profound Truth and understand the mysteries of space, they would actually have a high chance of locking onto his Void Shadow.

The Void Shadow was merely equivalent to being in another space-time; it wasn't that it truly didn't exist. As long as it existed, it must be within the Space Profound Truth.

Once the Void Shadow was locked, he would naturally have nowhere to hide.

Of course, the supreme Profound Meaning wasn't something just anyone could come into contact with.

For now, Li Yun didn't need to worry too much about this issue.

But humility was definitely necessary.

Facing Evil Blade Supreme's praise, Li Yun didn't appear arrogant. He smiled modestly, replied with a few words, and arrived at the entrance of the palace dungeon.

He habitually opened his 【Heaven and Earth Eye】 to scan the palace dungeon entrance.

Immediately, his heart gave a violent throb.

Previously, outside the palace, he had sensed a demonic intent within and immediately judged that there were Demon Race experts hidden inside.

But at that time, he really hadn't discovered any problem with the palace dungeon.

Until this moment.

Standing personally at the entrance of the palace dungeon, Li Yun discovered that this place was not simple at all.

Even the System was triggered.

【Observing the residual Immortal Charm of the Devil Subduing Platform, martial cognition points +80 billion...】

【Observing the residual Immortal Charm of the Devil Subduing Platform, comprehending the immortal technique Demon Slaying Blade... Loading...】

Li Yun almost cried out on the spot.

He was shocked beyond measure.

Immortal Charm?

At the entrance of the palace dungeon, the System actually perceived Immortal Charm and even loaded an immortal technique...?

Could this so-called Immortal Charm really be the 'Rhythm of Immortals' as he understood it?

Then how astonishing were the secrets hidden within this palace dungeon?
