I am grinding experience in another world

Within the Divine Statue Cave Heaven.

With a thought, the space before his brow twisted, and the bald, Heavenly Demon Body appeared out of thin air.

As consciousness settled into the Heavenly Demon Body, Yin Spirit Divine Power surged like a neural network throughout him, causing the Divine Ghost Patterns etched all over his body to burst forth with light.

Chen Mu took a careful look and immediately realized that all the Secret Techniques he had learned from the Yin Spirit side were inscribed within his flesh and bones in the form of Divine Ghost Patterns. Deploying these Secret Techniques was as natural and effortless as eating or drinking, carried out with just a thought.

He looked down at his True Flesh Body reclining on the chair, trying to activate the True Meaning Talisman within the Jade Seed. However, as soon as the thought arose, his consciousness had already returned to his True Flesh Body.

"The United Heart Curse belongs to the Qi Cultivation side of the Secret Technique, and since the Heavenly Demon Body possesses only Yin Spirit Divine Power and not Mana, trying to directly cast the United Heart Curse evidently won't work," he mused.

"Hmm, could I use an embroidery secret record to implant the United Heart Curse into the Heavenly Demon Body, treating it as some kind of Secret Technique?"

After pondering, Chen Mu shook his head.

The embroidery secret record could implant the essence carrying the monster's aura within one's body, acquiring its Innate Divine Ability after nurturing and strengthening it, akin to grafting a variant onto a plant.

But the United Heart Curse was different from Divine Demon Monster Mystical Powers. Its core lay in the True Meaning Talisman within the Jade Seed. Without the Secret Technique's aura remaining on the Fleshly Body, the embroidery secret record would not be viable.

"Either I need to turn the True Meaning Talisman from the United Heart Curse into a Divine Ghost Pattern, allowing the Heavenly Demon Body to directly activate it,"

"Or I must use Yin Spirit Divine Power to mimic Mana, weaving the True Meaning Talisman of the United Heart Curse within the Heavenly Demon Body," Chen Mu contemplated thoughtfully.

Mana is fundamental for Qi Cultivators, while Yin Spirit Divine Power is unique to the Netherworld. How to convert between the two is not even clear to top-tier Qi Cultivators and entrenched specters.

"It's worth pondering over the True Meaning Talisman," he mused.

The core of Qi Cultivator's Secret Techniques lies in the True Meaning Talisman, as does the core of Yin Spirit Secret Methods in the Divine Ghost Patterns. Though externally different, fundamentally they are similar, both being a manifestation of some innate ability bestowed to heavenly demons, gods, and spirits.

"If I could transform the True Meaning Talisman of the United Heart Curse into a Divine Ghost Pattern, the Heavenly Demon Body would be able to cast the United Heart Curse smoothly," he thought.

Chen Mu summoned the gray wall and focused on the secrets behind the True Meaning Talismans and the insights into the Yin Spirit's Secret Methods, trying to find common ground between them.

...

Half a month later.

Within the Divine Statue Cave Heaven, in the City Divine Main Hall.

Chen Mu lay sprawled on top of the offering table, supporting his cheek with his left hand, while his right hand flashed with arcs of lightning as he stared helplessly at the Divine Statue that bore a fifty to sixty percent resemblance to himself.

"What am I to do with you?" he muttered to himself.

According to his plan, with the secrets of the True Meaning Talisman on the gray wall and relevant information on Divine Ghost Patterns, there should have been an easy way to identify a substitute relationship between the two.

But reality was telling him that he was completely delusional.

After half a month of pondering, Chen Mu had gotten nowhere.

"Do I really have to be imprisoned in this Divine Statue Cave Heaven for a hundred years?"

"Even if Divine Orifice reaches Perfection and my lifespan extends to over two hundred years, this isn't the way to waste it," he sighed.

Sighing, Chen Mu turned and laid on his back on the offering table, crossing his left leg over his right knee, shaking his left foot while contemplating all the Secret Techniques he had learned in hope of finding a way out of the Divine Statue Cave Heaven.

In the faint recesses of his mind, a web of noise began to surface. But before he could discern it, the noise vanished as quickly as it appeared.

Chen Mu's brows lifted, and with a thought, a round and plump shining bead materialized before him, surrounded by countless luminescent specks, like a galaxy.

This was the Yin Spirit Divine Fetus, a manifestation of the Heavenly Demon Body's innate ability to trace back to its origin.

Now when he listened, the noise that had vanished by his ear reemerged, and upon closer inspection, it was the full passage of the East Pole Longevity Scripture.

"Is someone inducing the Heavenly Demon Spirit Seed?"

"Feng'an City?" Chen Mu's eyes narrowed.

This scripture appears quite proper, but in reality, it's quite nefarious. Its essence is the Heavenly Demon Curse; merely by reciting it in silence, one unwittingly has the Heavenly Demon Spirit Seed planted within them.

Whoever has the Spirit Seed implanted will find within their consciousness a vast black canopy dotted with stars.

Each star represents a Secret Technique, containing all the experience and insights Chen Mu has mastered.

Those who share this connection can meditate on it often, accelerating the practice of that Secret Technique manifold.

If Chen Mu were willing to transfer knowledge actively, he could even allow the Spirit Seed bearer to instantaneously master that Secret Technique.

But to truly be implanted with a Spiritual Seed, one would first imperceptibly come under its influence, beginning to grow close to Chen Mu. They wouldn't be completely obedient, but they definitely wouldn't entertain any harmful thoughts.

Furthermore, once they died and the Heavenly Demon Spirit Seed returned, it would take away some trait from the other party that Chen Mu himself was unclear about.

It was akin to a particularly malicious loan, offering secret techniques and experiences during one's lifetime, but claiming everything once they died.

He always felt that this secret technique was somewhat sinister, used only in the Netherworld due to the dangers necessitating its use. Afterwards, he deliberately blocked out various voices coming from the feedback of the Spiritual Seed, keeping his distance intentionally.

However, those prayful voices that used to irritate him and put him on guard now sounded like the music of the immortals.

"To speak of vital energy connection, the distance that the Heavenly Demon Spirit Seed can connect far exceeds that of the United Heart Curse."

"One in the Yang Realm and one in the Netherworld, they can communicate across the distance of an entire world!"

"If I could implant a Heavenly Demon Spirit Seed inside the fleshly body..."

Chen Mu suddenly sat up with a roll.

"The current issue is, how to make the Heavenly Demon Spirit Seed parasitize the fleshly body," his eyes shone brightly.

He had previously experimented on Sun Ke, having him recite the East Pole Longevity Scripture, but even until the other party left Luandu County, the implantation of the Spiritual Seed had never been successful.

This indicated that, as he had suspected, the Heavenly Demon Spirit Seed could only parasitize Yin...

Wait a minute!

"That slick Sun Ke, could it be he never even recited the East Pole Longevity Scripture?"

"Acting submissive on the surface, but messing around behind the scenes?"

Thinking of the guts it took for the other party to open a Market District under the search of the Lock Dragon Courtyard, Chen Mu's eyes widened immediately, "I definitely collected too little money for his life!"

Gnashing his teeth in frustration for quite a while, he could only helplessly shake his head.

"In the end, I still need to try it myself."

Skipping the Longevity Scripture and directly chanting the Heavenly Demon Curse, a flurry of sounds suddenly arose around him as if thousands of people were whispering in low voices.

A Heavenly Demon Spirit Seed, small as a speck of dust, appeared silently and then, with an unstoppable momentum, furiously rushed towards him.

Just as it was about to drill into his brow, a flash of light flickered across his body.

Immediately afterward, with a 'pfft' sound, it was like a candle suddenly blown out by a person, or like sparks doused with a bucket of cold water. The furiously advancing Heavenly Demon Spirit Seed zipped out of existence without a trace.

Chen Mu's lips twitched, his rising joy dying in his belly instantly.

"Body Protection Aura?"

"As expected, this Heavenly Demon Spirit Seed is still that useless small thing."

Before the liaison of the Heavenly Demon Curse, the Heavenly Demon Spirit Seed couldn't even autonomously parasitize yin soldiers. Even facing ordinary Yin Spirits, he had to first control the other party, then forcibly cram it into their mouths to succeed.

"Mm, suppress the Body Protection Aura, and try again," Chen Mu braced himself.

The eerie murmur of the Heavenly Demon Curse sounded again, and another Heavenly Demon Spirit Seed appeared, rushing towards Chen Mu's forehead with fierce momentum.

Thud!

Like a ball bouncing off a southern wall, the Spiritual Seed came quickly and bounced back even faster, shooting away after being repelled.

Then, not giving up, it repeatedly charged at Chen Mu's forehead like a chick pecking at a stone, never giving up, never succeeding.

Tsk!

Chen Mu's lips twitched once more.

The Aura was indeed gone, but his years of cultivated skin were like armor, so the brave Heavenly Demon Spirit Seed couldn't penetrate it.

"How about just eating it?"

A moment later.

Chen Mu touched his belly, which felt nothing, his face expressionless.

"It couldn't withstand the stomach acid, the Cloud Mirage Celestial Demon is really still that bootless Demon God!"
