Let you simulate life, but you change fate every time?!

Half a day later.

A ball of light quietly floated in midair, emitting a faint yellow glow.

This was unmistakably the Third-Turn Slave Gu that Lu Yuan had refined using numerous Heavenly Materials and Earthly Treasures!

Once used, it would transform into countless rays of light, merging into the opponent's body, and could control all biological beings below the Core Formation Realm.

Lu Yuan did not hesitate and immediately used the Third-Turn Slave Gu on Gao Qi.

Bang!

As soon as he activated his Spiritual Power, the Slave Gu suddenly exploded, transforming into numerous micro-lights that merged into Gao Qi's body.

"Relax your mind and merge with the Spirit Gu!"

Lu Yuan said in a low voice.

Although with his current power, he could completely force control over Gao Qi using the Slave Gu.

But if Gao Qi cooperated voluntarily, it would undoubtedly save him a lot of effort.

Upon hearing Lu Yuan's words.

Gao Qi hesitated for a moment, then abandoned all resistance, allowing the Slave Gu to merge with himself.

Instead, the parasite and Celestial Demon Seed in his body seemed to sense some kind of threat, instantly emitting a sharp, piercing insect cry.

One could see the deformed worm waving its tentacles, violently struggling to resist, attempting to drive all the faint yellow light out of its body.

Unfortunately.

When Lu Yuan was deducing the Slave Gu Formula, he not only referenced the Law Dao Pattern of the Celestial Demon Seed but also integrated some insights on the Parasite Insect Race.

The Slave Gu he refined not only could enslave Core Formation Cultivators but also control the parasites within their bodies!

In front of the Slave Gu, the worm had no power to resist; before long, it merged with the faint yellow light and was completely under Lu Yuan's control!

"Subordinate Gao Qi, pays respects to master!"

Gao Qi knelt on one knee, his gaze towards Lu Yuan filled with fanaticism and loyalty.

As if with just one word from Lu Yuan, he would climb a mountain of swords or plunge into a sea of flames for him, even at the cost of his own life!

At the same time.

The faint yellow glow all over Gao Qi's body gathered into a Soul Seal, silently merging into the depths of his soul.

At the moment when this Soul Seal appeared, Lu Yuan also felt a strange sense of connection.

It seemed that now he only needed a single thought to determine the life and death of Gao Qi and the parasite within his body through that Soul Seal!

"Stand up."

Lu Yuan said flatly, quite satisfied with the effects of the Slave Gu.

With the Slave Gu, he could develop numerous subordinates, spreading his eyes and ears throughout various sects, and never worry about betrayal!

Next.

Lu Yuan repeated the same process, implanting Slave Gu into other disciples of the Celestial Demon Sect.

The Slave Gu was colorless and formless, already integrated with those disciples' souls, and unless Lu Yuan revealed it himself, even a Divinity Transformation Ancestor couldn't detect its existence!

After finishing all this.

Lu Yuan had Gao Qi and the others return to the Celestial Demon Sect's ranks and continue lying low, while he chose a secluded place to calmly wait for the entrance to the Cyan Spirit Secret Realm to open again.

According to past conventions, all talented disciples could stay within the Secret Realm for a month.

After a month, all disciples, regardless of their location, would be automatically transported outside.

However, there were still a few days left until the Secret Realm closed.

With nothing to do, Lu Yuan took out a Jade Bottle from his Storage Ring.

The Jade Bottle contained a purple liquid that shimmered, seemingly composed of condensed lightning symbols, harboring boundless Power of Thunder Tribulation.

Just a wisp of its aura made Lu Yuan's entire body's vitality become significantly more active.

This was the Thunder Essence Liquid that Lu Yuan had acquired in the Secret Realm valley!

According to ancient records, Thunder Essence Liquid was a Supreme Treasure nurtured in the depths of Thunder Tribulation.

Even a drop of Thunder Essence Liquid could be sold for an astronomical price in the outside world!

After all, many cultivators excel in techniques, but their physical constitution seems somewhat weak, and this Thunder Essence Liquid is immensely beneficial for purifying the flesh body and enhancing physical strength.

Moreover, although Core Formation Strong Persons could invoke the Power of Heaven and Earth to form a domain unique to themselves,

how vast and magnificent is the Power of Heaven and Earth?

In the face of the boundless heavens, Core Formation Cultivators are as insignificant as ants, and even a sliver of Heaven and Earth's power could crush most cultivators!

Therefore, upon reaching the Core Formation Realm, tempering the flesh body is also a crucial step.

The stronger the flesh body, the more Heaven and Earth's power it can bear, thereby greatly enhancing one's combat power!

Like the Vajra Peak of the Medicine Buddha Sect, which follows the path of the Body Cultivator, if a disciple reaches the Core Formation Realm, they become immensely powerful, like a humanoid dragon.

Capable of splitting mountains and traversing hundreds of thousands of kilometers in a day.

With a mere gesture, they can unleash a force as terrifying as moving mountains and seas.

And with Lu Yuan's heaven-defying comprehension, dual cultivation of Body Technique and Daoist Skill, his battle power surpasses others of the same realm by dozens of times.

However, this bottle of Thunder Essence Liquid is too little, only enough to enhance his Indestructible Vajra Body to Great Success.

If he had enough Thunder Essence Liquid.

He could instantly cultivate this cultivation technique to Perfection, and by then, even confronting a Nascent Soul Strong Person head-on wouldn't be a problem!

Lu Yuan shook his head, not wanting to think further.

Then, with a thought, he tilted his head back and swallowed all the Thunder Essence Liquid, turning it into boundless energy that spread from his Dantian to every part of his body!

Buzz!

Almost at the moment of fusion.

Lu Yuan was enveloped by a vast Power of Thunder Tribulation.

Electricity was born in the void, runes interwoven.

Dao Patterns of Thunder emerged one by one, imprinting onto Lu Yuan's flesh, blood, and bones.

At this moment.

Lu Yuan endured unimaginable pain.
