In the space, before Xiao Fei, spiritual energy condensed, constructing meridians and circulation pathways similar to the human body.
A stream of spiritual energy moved slowly through these meridians along an extremely complex route.
When this stream of spiritual energy traced a profound trajectory within the meridians, a burst of flame immediately erupted.
Xiao Fei hastily controlled the spiritual energy to change its route, but it was already too late.
"Boom!"
The ball of flame exploded, shattering the meridian model he had constructed.
"Sigh! Have to start all over again!"
Within the space, he could freely manipulate spiritual energy, which provided him with convenience in creating cultivation techniques.
He constructed meridian models of the human body with spiritual energy, then simulated the circulation of cultivation techniques within the meridians using spiritual energy.
After Xiao Fei had thoroughly understood all cultivation techniques, he spent another 200 years designing 129,673 preliminary schemes.
Each scheme had a different design concept and method of spiritual energy circulation, representing a direction of development.
However, this was merely the result of theoretical planning; whether it would actually work needed to be tested through practical cultivation.
But practicing unverified cultivation techniques carried immense risks, potentially leading to death.
It was possible that the incredibly talented Hunyuan Old Ancestor had died in this very manner.
Xiao Fei's sudden inspiration led him to devise this idea of modeling within the space.
Seeing the shattered meridian model, Xiao Fei inwardly felt fortunate, realizing that such an incident within his own body would have been fatal or severely injurious.
He tidied up the mess and drew a cross in red ink on a jade slip.
Next, he would rebuild the meridian model and test another set of cultivation techniques...
...
Another 200 years passed, and all 129,000-plus schemes were tested.
After removing those with safety hazards and those with poor efficacy, over 300 cultivation techniques remained usable.
These 300-plus techniques each had their own merits and drawbacks, making selection difficult...
...
"Hahaha... Hahaha..."
"I've finally succeeded... Hahaha..."
Xiao Fei spent another 500 years consolidating and merging the remaining 300-plus techniques into a brand new cultivation method.
This new technique had been tested in the space for a year, proving to be powerful and safe.
He named this new technique "Hunyuan Gong," removing the two characters "Five Elements" from its original name.
While the new technique was still based on the Five Elements, it was no longer limited to cultivating Five Element spiritual roots but was more inclusive.
The new technique perfectly resolved his current Five Element imbalance and also left open pathways for the other four elements: Fire, Earth, Metal, and Water.
In the future, if he were fortunate enough to find spiritual fruits of the other four attributes and refine them into Marrow Cleansing Pills, he could also elevate the other four elements.
It was even possible to raise all Five Element spiritual roots to over 100 points, transforming himself into an unprecedented cultivation prodigy.
After cultivating the new technique, he could still utilize the Five-Colored Divine Light and Hunyuan Divine Thunder he had previously mastered.
On the stone bed in the secret chamber, Xiao Fei, who had been lying dormant for nearly fifty years, finally moved.
He reached out and wiped away the accumulated dust and cobwebs from his face, then slowly sat up, stirring up a cloud of dust.
Suddenly, a gust of wind swirled around Xiao Fei, raging through the secret chamber and instantly cleaning the interior, sweeping all the dust into a corner.
He stood up, stretched, twisted his neck and waist, and moved his limbs. Having been inactive for so long, his body was stiff as a zombie.
After moving around, he casually struck a pose and slouched onto a chair, circulating the spiritual energy within his body according to the "Hunyuan Gong" incantations.
The modified technique he practiced required no specific postures; it could be cultivated while walking, sitting, or lying down.
The moment "Hunyuan Gong" began to circulate, the surrounding spiritual energy of heaven and earth surged into his body.
Regardless of whether it was Wood, Fire, Earth, Metal, or Water spiritual energy, upon entering his body, it was rapidly refined into spiritual power.
This cultivation efficiency had improved by several levels compared to before.
During cultivation, Xiao Fei's aura changed, becoming eerily spectral. His entire spiritual power transformed instantly into pure, ghost-like energy.
Immediately afterward, it turned into demonic energy, and even his form began to change, transforming into the appearance of a Black Scale Demon.
He then took out the two large hammers from the space, carrying one in each hand, perfectly embodying the Black Scale Demon.
Among the various cultivation techniques he had studied, those involving transformation and disguise were naturally included.
After thoroughly understanding all cultivation techniques, he had also integrated some more practical minor skills into the method.
"Hunyuan Gong" included corresponding methods for transformation, disguise, aura concealment, and cultivation suppression.
Xiao Fei tested the new technique and was very satisfied.
He retracted his cultivation and walked out of the cave dwelling. Huang Feifei did not seem to be there.
Xiao Fei concealed his aura and casually wandered around Meteor Star Island.
He discovered that during his nearly fifty years of seclusion, Meteor Star Island had undergone earth-shattering changes.
Numerous luxurious residences and palaces had been built on the island, and all the disciples of the Lu Sect were equipped with uniform magic robes, exuding an imposing aura.
A large marketplace had been constructed in the center of Meteor Star Island, with a large number of foreign cultivators coming and going, all drawn to this marketplace.
Xiao Fei also strolled into the marketplace, where many shops were run by visiting merchants.
He even saw a trading company operated by several rat demons.
The goods sold on the island included specialties from the Eastern Continent, as well as specialties from the East Sea, and many more products bore the Lu Sect's mark.
Walking through the crowd, Xiao Fei listened to people's conversations and learned from them that the Eastern Continent had become a mess. The Great Qin Dynasty, which had just unified the land, was in dire straits after only a few decades.
The Great General, who had performed exceptionally and been undefeated in the unification war, was no longer as valiant in battles against the demon race, suffering repeated losses.
With the military setbacks against the demons in the west, many hidden enemies within the country were stirring, and unrest incidents would erupt from time to time.
In addition to these hostile human factions, many lurking demons also took the opportunity to cause trouble within the Great Qin Dynasty.
In an instant, the Great Qin Dynasty, having just unified the land, was engulfed in flames, with constant warfare and a desperate struggle for survival.
However, the disaster on the Eastern Continent provided the Lu Sect with an excellent opportunity to prosper.
Meteor Star Island had now become the trading hub between the East Sea and the Eastern Continent, enjoying a certain reputation throughout both regions.
In the past few decades, under Huang Feifei's leadership, the Lu Sect had developed rapidly. Along with its increased wealth, its strength had also grown swiftly.
Xiao Fei saw several spirited Golden Core cultivators of the Lu Sect along the way.
He vaguely recognized some of them as former Foundation Establishment cultivators of the Lu Sect; he hadn't expected them to reach the Golden Core stage in such a short time.
Learning that the current prosperity of Meteor Star Island was entirely built by Huang Feifei, Xiao Fei could not help but admire her greatly.
He was not short of money due to the existence of his space.
However, Huang Feifei had led the entire Meteor Star Island to prosperity and wealth earned genuinely from others.
