Li Mo gazed at the Liu Li jar containing the Spirit Root and Spiritual Energy, as the fragmentary memories from the Creation Book caused a faint swelling in his head.
As he digested these memories, he learned a lot about the Spiritual Energy.
To be precise, it was the Spiritual Energy from the ancient Cultivation World.
Seven thousand years ago, Spiritual Energy was colorless and formless, a very pure energy that only manifested as a mist-like form when its concentration reached a certain level.
Spiritual Energy existed in every corner between heaven and earth.
At that time, cultivators were unable to bind Spiritual Energy, even using the Spirit Gathering Array could only slightly increase its concentration.
Only naturally formed Spirit Veins could be mined to obtain crystal-like Spirit Stones.
Cultivation Sects were generally located around Spirit Veins, using large Spirit Gathering Arrays to collect the Spiritual Energy leaking from the Spirit Veins, forming a Blessed Land Cave Heaven.
Spirit Stones were graded based on the concentration of Spiritual Energy, divided into Low Grade Spirit Stone, Mid-grade Spirit Stone, High Grade Spirit Stone, and Top-grade Spirit Stone.
Li Mo viewed from the perspective of the Heart Beast Sect.
The system of the ancient Cultivation World was entirely built upon Spiritual Energy, whose characteristics only consisted of the Five Elements: metal, wood, water, fire, earth.
Spirit Root was the organ used by cultivators to absorb Spiritual Energy, mainly composed of the Five Elements Spirit Root, equivalent to talent.
A cultivator's Spirit Root was located in the Mud Pill Palace, its appearance similar to a rhizome.
The purer the Spirit Root, the more efficient the cultivation, a Single Spirit Root was called a naturally born Tao Seed, with no bottlenecks before the Golden Core Stage, whereas the Five Elements Mixed Spirit Root found it difficult to break through even to the Foundation Establishment Stage.
Li Mo looked at the numerous Liu Li jars before him.
In one Liu Li jar, the Spiritual Energy unexpectedly appeared in a purple viscous form, soaking in it the Five Internal Spirit Roots, with a coral-like keratin layer covering its surface.
There were over sixty jars in the room by estimation, with almost no repetition of Spiritual Energy types, some resembling magma, or ice sand, the most peculiar being composed of a vast number of worms.
Ka ka ka ka...
Metals clashed upstairs, seemingly a massive creature was crawling slowly.
Li Mo knocked on the wall, although covered with a layer of wood externally, inside it was forged from metal ore, making it exceptionally sturdy.
The mountains near Rong Town had never been known for iron mines, yet the Medical Hall used several tons of metal to construct the building, could it be merely to accommodate Spiritual Energy?
Li Mo swallowed a gulp with difficulty.
The Liu Li jars carrying Spiritual Energy felt exceptionally dangerous, as if they were filled with bombs about to explode at any moment.
"Cough cough cough."
"Little one, who allowed you to come looking for this old man?"
"Steward Hu asked me to come to choose a Cultivation Technique..."
An aged and robust male voice echoed within the stairs, soon appearing a body at least three to four meters high, supported by eight spider-leg-like arms.
Li Mo retreated several steps, the large door behind him suddenly closed automatically.
Meanwhile, hundreds of candles within the room lit up in succession, and the Liu Li jars hanging from the ceiling sparkled like stars in the night.
"Interesting, interesting!!"
Han Cai's head emerged, appearing like an average middle-aged man, his untrimmed beard hanging upon his chest.
But his body was at least two meters high, and bizarrely oval-shaped, supported by eight elongated, emaciated human hands.
Han Cai had only an upper body, covered with a tattered Daoist robe, concealing his bloated body.
Continuously, palm-sized spiders crawled out from the bottom of his Daoist robe.
Li Mo couldn't help feeling scalp tingling. Could excessive dual-cultivation of Spells turn one into a Non-human feature monster like Han Cai?
Ten or so doctors pursued Han Cai anxiously, evidently, some surgeries remained unfinished.
"You all head up first, the old man will surely come over soon."
The leading one-eyed doctor hesitantly said, "Doctor Han, but the time..."
Han Cai glanced at them, the doctors hurriedly returned to the second floor swiftly, leaving Li Mo to bear the suffocating pressure alone.
"Little one hasn't even entered the sect yet, quite rare for Hu Wen to push you over."
"Childhood is the process of nurturing the Five Internal Organs with Alien Spirit Energy, causing the Five Internal Organs to transform into a Corpse Spirit Root, choose your Spiritual Energy yourself."
Li Mo calmed his mind, he wasn't sure why the Spiritual Energy in later generations was so bizarre, but clearly, the ancient Cultivation Techniques no longer applied.
He clasped his fists and said, "I request Doctor Han to enlighten me on the strengths and weaknesses of the Spiritual Energy."
"Hahaha, good eye!"
"The types of Spiritual Energy collected by the old man are the most in all of Rong Town."
Han Cai stretched out his hand, his joints making a strange sound as they extended several meters, rummaging through the cupboards at the side of the wall.
"Got it."
Han Cai pulled out a Bone Scroll.
"Much appreciated, Doctor Han." Li Mo placed the Bone Scroll at his brow upon receiving it.
Seven thousand years of transformation changed not just grass, wood, mountains, and stones, even Spiritual Energy underwent inexplicable changes.
Spiritual Energy was no longer pure, giving rise to numerous distinctive Alien Spirit Energies.
Cloud mist, swamp, volcano, thunder, plants, bones... all would nurture Alien Spirit Energy.
The present Cultivation Techniques were founded on Alien Spirit Energy.
Innate Spirit Roots no longer existed, hence childhood required the transformation of the Five Internal Organs into a Corpse Spirit Root.
The Corpse Spirit Root would possess the characteristics of Alien Spirit Energy, hence, appearing in various forms.
No wonder it involved compatibility of Skill and Magic.
Spell and Alien Spirit Energy had to align, otherwise, the power of the Spell couldn't be wielded effectively.
Han Cai picked a jar of red and yellow interwoven Spiritual Energy from the Liu Li jars, the Five Internal Organs inside were also of rocky material, cracks littered its surface.
"This is Mountain Spirit Qi, which the old man excavated from deep within a geophysical vein, it's characteristic is Spiritual Energy suitable for all defensive spells."
"Doctor Han, it's not suitable for me."
Li Mo hesitated a few moments before speaking against it.
Hui Qingyi was a protective Spell in ancient times, and Mountain Spirit Qi should have suited it well.
But given how much Steward Hu valued it, Hui Qingyi shouldn't be so ordinary.
Li Mo sought more of a versatile Alien Spirit Energy, without obvious flaws and drawbacks to accommodate most spells.
"Hmm."
"How about Jade Liquid Spirit Energy?"
He picked up a jar of milk-like Spiritual Energy.
"Jade Liquid Spirit Energy is extracted from the heart of a thousand-year-old tree, after refining, it nourishes the vitality of the Five Internal Organs, Weak Crown Death Disease, relying on Jade Liquid Spirit can at least delay it by fifteen years."
"Or this Filthy Spirit Energy, the source... ahem, the source shall remain undisclosed for now."
"Filthy Spirit Energy is not hard to find, ensuring your cultivation efficiency, and unquestionably powerful, as the energy is highly toxic."
While handling Han Cai, Li Mo also focused on the various Alien Spirit Energies.
For him, with the Creation Book in hand, there was no way he'd refine just a single type of Spiritual Energy; multiple imprinted organs could increase the number of Dantian.
The first time refining Spiritual Energy, it seemed prudent to play it safe.
Han Cai's incessant chatter sounded beside him, while Li Mo concentrated his formidable thinking ability, honing the skill of multitasking to its peak.
Li Mo occasionally inquired Han Cai, trying his best to understand the characteristics of each jar of Spiritual Energy.
His gaze focused on a smoke-like Alien Energy, and then shifted away.
Cloud Mist Spirit Energy suited Li Mo's idea of versatility, but unfortunately, it was more fitting for Illusion Techniques, otherwise, it was low-tier in offense and defense.
"Doctor Han, what is this..."
Li Mo pointed to a corner, it was likewise a jar of cloud mist-like Spiritual Energy, but it appeared pale yellow, the Corpse Spirit Root within was akin to the Swamp Poison Spirit Energy, as if viscera soaked in wax oil.
