I am grinding experience in another world

In Qiluo Mountain City Divine Temple, Li Buxian was shaking with fear.

"How could the City God make an appearance in the Human World?"

According to the records of Lock Dragon Courtyard, in the nearly three hundred years since the founding of Da Qian, there has never been a manifestation of the City God. Instead, there were rumors of God Statues being destroyed, and Worldly Gods disappearing together.

Do I really have that much clout to warrant a personal visit from the City God himself?

The person before my eyes...

The person before my eyes is probably not the City God at all!

Li Buxian's heart lightened.

Is it the Great Heavenly Demon using the face of the City God to intimidate me?

He shook his head to himself.

Despite sensing that the Demon Seed's vital energy was indeed connected to the person before him, his disbelief only grew stronger. The Great Heavenly Demon, who stays high in the Nine Heavens and never descends to the Human World, would not be so idle.

This is likely to be a fellow practicer on the Demon Path using a trick to assume the authority of Divine Demons to command me.

Li Buxian sneered inwardly.

I didn't make it to where I am today without a real fight.

You think you can deceive me and treat me like I'm soft?

Ha!

"I don't know which fellow practicer on the Demon Path stands before me, but you'd better show your true face to meet me."

"You should not offend the majesty of Divine Demons; if you impersonate one without authority, you're likely to incur heavenly punishment!" Li Buxian said with a cold expression.

Chen Mu's eyebrows lifted.

A fellow practicer on the Demon Path? Show my true face?

No wonder this old guy was trembling just now, and then suddenly became defiant. He mistook me for someone impersonating a City God to scare people.

And talk of heavenly punishment? He's indirectly cursing me!

"Are you sure you want to see my true face?" Chen Mu asked, his eyebrows slightly raised.

"What? Is that face of yours too disgraceful to show?" Li Buxian sneered coldly, surely this is some Heavenly Demon jackass trying to play me!

"I'm just afraid I'll scare you away," Chen Mu said with a smile.

Old man, what storms haven't I seen? I won't be scared of you!

Just as Li Buxian was about to retort with scorn, a familiar face appeared before him.

"Cloud Piercer Gongsun Sheng?!"

"How dare you show yourself so brazenly before me!" Li Buxian's brows furrowed, his face cold.

"Lock Dragon Courtyard has never given up on capturing you and bringing you to justice. You..."

"You weren't spotted coming here, were you?"

"Is there something you need me to do?"

"Just give the command, and I assure you, I will do everything in my power to make it happen!" Just moments ago, Li Buxian was bristling with murderous intent, but now he seemed as if he'd seen his parents reborn, his face beaming with kindness.

You really do flip sides damn fast.

Sly old fox!

"I still prefer that unyielding face you had just now," Chen Mu teased with a laugh.

You think I damn well don't want to? Only if I could beat you, that is.

Li Buxian's expression remained unchanged, though his heart was already back in his throat.

He had no desire to relive the experience of having his ribs kicked into his heart.

Bow and scrape?

No no no, this is called making pragmatic concessions.

Staying alive isn't humiliating!

...

Two days later, in the Divine Statue Cave Heaven.

Chen Mu sat in a rocking chair under the Moon Gate, holding a thin book and reading.

"Green Satchel Chapter" – three simple seal characters were written on the title page, marking the starting point for all Underworld God Transformation practices.

This technique was divided into Active and Quiet Cultivation; the Active Cultivation consisted of seventy-two guiding movements, while the Quiet Cultivation was an awkward and cumbersome scripture.

He had pondered for two days and tried practicing himself.

To him, the seventy-two movements of Active Cultivation were expansive and graceful, good for stretching the muscles, promoting blood circulation, and aiding digestion, but essentially... essentially pointless!

The body refinement capability he had imagined wasn't there, not even a little. He had recited the Quiet Cultivation text hundreds of times, also to no effect.

After two days of struggling, the Gray Wall didn't offer him a shred of insight!

Having cultivated for many years and encountered dozens of magical techniques, even with the deceiving Calculation Scripture, the Gray Wall would give him some enlightenment. However, the Green Satchel Chapter elicited no response.

"Is that old guy Li Buxian fooling me?"

"So daring?"

...

"Heavenly Capital Pool?"

"What is that?"

In the East Straddling Courtyard of the City Divine Temple, Chen Mu sat opposite at the square table, full of confusion as he looked at Li Buxian.

After pondering the Green Satchel Chapter for two days without making heads or tails of it, he immediately rushed to seek out Li Buxian. The old man before him had long since cultivated to the pinnacle of the Underworld God Seven Transformations, and was most familiar with the Underworld God Transformation.

"There are mainly three ways to learn Underworld God Transformation in Da Qian. They are through the military, the Lock Dragon Courtyard, and the secret family traditions of titled nobility." Li Buxian spoke with utmost respect, withholding nothing.

"Besides having control over various precious pathways to the Underworld God Transformation, what's most important is that they are permitted to construct the Heavenly Capital Pool."

"The Heavenly Capital Pool can gather Incense Spiritual Energy, and it can summon the qi of Divine Demons; it is an indispensable part of the Underworld God Transformation cultivation."

"Cultivating the Green Satchel Chapter is for changing one's constitution to create a Jade Seed; it must be practiced in a place rich with Incense Spiritual Energy, otherwise progress will be very slow."

The Green Satchel Chapter requires Incense Spiritual Energy?

Chen Mu couldn't help but lift his head to look at the top of Qi Luo Mountain, where there was a vast expanse of stable Incense Spiritual Energy clouds. Stay connected via My Virtual Library Empire

Without external interference, this stuff would all be absorbed by the Lock Dragon Well; there's none inside the Divine Statue Cave Heaven, naturally unable to aid in the cultivation of the Green Satchel Chapter.

Is it the lack of Incense Spiritual Energy that results in no progress on the gray wall?

Chen Mu slowly shook his head.

According to Li Buxian, without Incense Spiritual Energy, cultivation would be very slow, but not impossible.

Incense Spiritual Energy has an influence, but there must be other reasons for the complete lack of progress in my Green Satchel Chapter!

He narrowed his eyes.

What is the difference between Li Buxian and myself? Is it because I am a Qi Cultivator?

Noble families in Da Qian already have Qi Cultivators among them, but they can still cultivate both Underworld God Transformation.

If there's a real difference... it's that I was not born in Da Qian!

Anyone born in Da Qian has a Netherworld Worm enter their body from a young age, and the Underworld God Transformation is closely related to Netherworld.

"Netherworld Worm..." Chen Mu realized something.

Mortal Martial Dao has its limits, to continue ascending, one either refines Vital Energy to forge a Shell Soul, achieving Spirit and Soul Unification to cultivate a Jade Seed, and then start Qi Cultivation toward immortality.

Or swallow the Heavenly Demon Rebirth Pill, absorbing the essence of demons, and practice the Heavenly Demon Reincarnation Technique to transform one's body into a Heavenly Demon True Form.

Netherworld Worms have the ability to strengthen the host's body, and the Underworld God Transformation can elevate mortal martial arts; perhaps it is an evolution derived from this basis.

"That seventy-two posture guiding technique isn't meant for humans to practice at all, but for Netherworld Worms inside the body."

"So, do I first need to find a way to get a Netherworld Worm into my body?" Chen Mu shuddered at the thought.

The thing is alive!

This... this is going to be tricky.

...

Several days later in the evening, Divine Statue Cave Heaven.

Under the shade of a tree next to the Moon Gate of the East Straddling Courtyard, Chen Mu lay in a rocking chair, squinting towards the fiery red sunset.

On the index finger of his right hand hung a simple, black cord ring, which rotated slowly on his hand like prayer beads under the manipulation of his thumb.

"United Heart Rope, United Heart Curse, United Heart Gu—all these series of Magical Instrument Secret Techniques are related to the Netherworld Worm."

"Both the Five Ghosts Bag and Five Ghosts Moving Mountain are related to Ghosts."

"And both come from the Thousand Mountains Sutra, a side sect's secret scripture."

"It seems that the Thousand Mountains Path, a major side sect from Ancient Times, also studied the Netherworld."

"Fortunately, the Wu Mountain seven brothers only implanted the United Heart Gu in me, and I didn't have the chance to encounter the Underworld God Transformation. Otherwise, right at the first contact, I would probably have been finished."

Chen Mu looked down at the United Heart Rope.

To break away from the grotto heaven, he needs to connect his Heavenly Demon Body to his Fleshly Body using the Heavenly Demon Spirit Seed.

To implant the Heavenly Demon Spirit Seed into his Fleshly Body, he needs to practice the Underworld God Transformation.

To practice the Underworld God Transformation, he first needs to get a Netherworld Worm into his body.

He's been struggling with this for several days, even trying to figure out other plans to leave the dojo, but unfortunately...

"There's no other choice..." Chen Mu let out a slight sigh.

With the flow of mana, a thin black line like a piece of hair separated from the United Heart Rope, drifting slowly and lively in front of Chen Mu.

Rather than relying on the City God Dojo to snatch the Netherworld Worm and end up at the mercy of the Netherworld authorities, it's better to implant the United Heart Gu into myself.

The essence of United Heart Gu is the Netherworld Worm, and with the United Heart Rope in hand, that Netherworld Worm would be completely under my control.

With his mind made up, the thin black line that was the Netherworld Worm zipped into his chest.

He got up and began the Active Cultivation Guiding Technique of the Green Satchel Chapter.

After just one repetition, a sudden buzzing sound rang in his ears.

A faint but entirely distinct beat, alien from his original heart, appeared silently within his body, as if he now had two hearts.

"It worked..."
