57: The Devil in the Heart of Tao

"Demon, not summoned but arrived because of me..."

Li Ke's mind became one.

The wild aura around him gradually subsided, and his fluttering robes slowly fell.

He looked within himself.

Within his Dantian, a dark and profound black Spirit Pool quietly floated.

In the pool, an inch of black Demonic Liquid had accumulated.

Above the Spirit Pool, wisps of black Qi continuously rose.

Those black Qi twisted and changed in the Void Realm, forming distorted and pained black human figures, which then silently merged into the surrounding Void Realm and disappeared.

"No wonder it's called the Demon Summoning Scripture..."

Li Ke thought to himself.

If he hadn't entered the Foundation Establishment Stage,

And deepened his understanding of the Demon Summoning Scripture,

Li Ke truly wouldn't have noticed,

That the characteristic of All Things Demon Infusion had already created so many strange demonic creatures within this castle.

Just now, when he recalled the Devilish Qi,

Those strange demonic creatures did not perish, they merely temporarily fell silent.

As the Devilish Qi in the Spirit Pool dissipated,

This group of demonic creatures would soon revive, and their numbers would only increase.

Summoning Demon means summoning and commanding all demons under heaven.

Just a single All Things Demon Infusion,

Could continuously infest the surrounding environment and create strange demonic creatures one by one.

And after Foundation Establishment,

Li Ke also gained another core Divine Ability from the Demon Summoning Scripture,

Dao Heart Demon Seed.

This Divine Ability allows him to plant a demon seed within others, granting them top-tier Demonic Path Aptitude.

But at the same time, they also become "Devil Heads" that the Demon Lord can summon and command at any time.

Even their Cultivation achievements can be called upon by the Demon Lord, forever unable to transcend.

"Demon, indeed not summoned but arrived because of me."

Li Ke's eyes flickered,

A smile gradually appeared on his face.

Before, he had always been somewhat troubled.

The Legacy on the demon-referencing tablet was vast as a sea of smoke,

But his energy was limited, making it impossible to Cultivate many Cultivation Techniques simultaneously.

That would be to be broad but not deep, becoming a burden instead.

What's more, those top-tier Demonic Path Legacies,

Which one didn't possess the domineering characteristic of 'only I am supreme,' and were inherently difficult to be compatible with each other.

He could only look at each top-tier Demonic Technique and sigh in resignation.

But now, with Dao Heart Demon Seed,

The countless top-tier Legacies on the demon-referencing tablet finally had a place to be used.

As long as he spread these top-tier Legacies through the demon seeds,

And then used the characteristics of the demon seeds to call upon their Cultivation achievements at any time...

This was equivalent to the Dao fruits of various top-tier Demonic Path Legacies all returning to him, instantly transforming him into the source of the Demonic Path...

"As expected of a Heavenly Dao taboo, truly terrifying!"

Li Ke slightly calmed his mind.

He was not in a hurry to exit his seclusion for now.

Instead, he immersed his mind into the demon-referencing tablet,

And began to comprehend some advanced secret methods of Golden Gate Paper Piercing and Yin Corpse Secret Canon.

A moment later, Li Ke slowly opened his eyes.

The profound black in his pupils gradually faded, revealing dark red pupils.

He casually pulled out an ordinary white letter paper from the drawer of the desk in front of him.

His slender fingers flew, quickly folding the letter paper into a lifelike butterfly.

With a trace of pure Devilish Qi injected.

The color of the white paper butterfly rapidly deepened at a visible speed,

Gradually turning into an entirely black Underworld Butterfly.

Its wings, thin as cicada wings, gently flapped, slowly flying up from Li Ke's hand.

A wisp of pure Devilish Qi emerged from Li Ke's fingertip.

The black paper butterfly lightly landed on his fingertip,

Sucking the wisp of Devilish Qi gently, Li Ke a real butterfly feeding on nectar.

A moment later, the black paper butterfly's wings slightly vibrated,

And it actually split into two, transforming into two identical black paper butterflies.

The two paper butterflies simultaneously landed on his fingertip, and began to suck the Devilish Qi together.

After a while, the paper butterfly's wings vibrated again,

Transforming into four paper butterflies, competing for the Devilish Qi around Li Ke's finger...

Yin-producing Underworld Butterfly,

This is an advanced paper butterfly paper binding recorded in Golden Gate Paper Piercing.

It can continuously self-replicate and proliferate by absorbing Devilish Qi.

Because it possesses energy-absorbing characteristics, its sense of existence is extremely low, making it very suitable for intelligence gathering.

And it can serve as a carrier to amplify and extend a Cultivator's Spell, greatly increasing the casting range of the Spell, truly having infinite wonderful uses.

Clearly, after Foundation Establishment,

The Legacy of Golden Gate Paper Piercing truly began to display its due power.

Li Ke looked to the side.

Spirit boy and girl stood quietly in front of the bookshelf, and when Li Ke looked over, Spirit Girl's head tilted slightly.

The strength of this pair of paper figures had already shown a slight inability to keep up during the battle with the Ironwood Old Family Head.

"After I collect suitable Materials later, I'll upgrade them again..."

Li Ke's thoughts stirred slightly.

Two black paper butterflies silently flew out of the study.

......

In a room on the first floor of the castle,

Butler Barton was hunched over,

Gently wiping the picture frames hanging on the wall with a soft white velvet cloth.

Those oil paintings had distorted and grotesque styles, with intense and oppressive colors, exuding an unsettling and strange aura.

Barton's movements were gentle and focused, with an almost devout expression on his face.

A black paper butterfly silently flew into the room,

Gently landing on his shoulder.

At the same time, on the training ground of Charles Manor.

Hatties was bare-chested,

His bronze skin reflecting a strong luster under the sunlight.

He used only one index finger to touch the ground, yet his entire body floated cross-legged in mid-air in a manner that defied physical common sense.

His eyes were tightly closed, his breathing long and deep,

Maintaining the strange posture motionless, with subtle black spiral Qi swirling around him.

He was clearly Cultivating Nine Lives Spiral Skill.

Another black paper butterfly quietly landed on his tense shoulder.

"Come see me."

A calm and unwavering voice, without warning, echoed in Barton and Hatties's minds.

Barton's body trembled suddenly, he came back to his senses, and bowed slightly.

Hatties also suddenly opened his eyes, a black spiral flashed in his pupils, and he replied in a low voice: "Yes."

A moment later,

The study door was gently knocked.

Barton and Hatties entered the study, one after another.

Li Ke's gaze swept over the two of them.

In the depths of his dark red eyes, a dark and profound light flickered.

A moment later, a hint of disappointment flashed across Li Ke's face and eyes.

The Dao Heart Demon Seed Divine Ability requires selecting individuals with deep demonic nature.

The deeper their own demonic nature, the better the Aptitude transformed by the demon seed, the faster their Cultivation of Demonic Technique, and naturally, the better the feedback effect to the Demon Lord.

Therefore, what Li Ke wanted to select,

Were Devil Heads with deep demonic roots, who resented everything.

Just now, Li Ke observed Barton and Hatties.

Unfortunately, Hatties had a tenacious Heart-Nature and pure will.

Although he Cultivated Nine Lives Spiral Skill, his own demonic nature was not particularly deep.

He was not the best candidate for planting a demon seed.

As for Butler Barton...

His state was somewhat peculiar.

Because Barton had stayed in the castle the longest and had the most close contact with Li Ke,

He was deeply affected by the All Things Demon Infusion.

His entire being already showed a tendency to transform into a demonic creature.

Perhaps it was because of his excessive obsession with the profession of "Butler,"

Barton seemed to have formed a peculiar symbiotic relationship with the strange demonic creatures in the castle.

His state was very strange...

Li Ke couldn't tell for a moment whether this change was good or bad.
