The intelligence jade slip left by Xiao Lan for Xiao Fei not only included the movements of various countries on the Eastern Continent but also information on the disguised identities of many hidden demons.
With this intelligence, these demons could be ferreted out one by one.
Even if they weren't exposed, Xiao Fei would at least be able to guard against them when he encountered them in the future.
Xiao Fei reviewed everything. Most of these demons were hidden in the State of Ying Shan, with some in the State of Wu and neighboring countries.
Even within the Lu Sect, two demons were currently hidden.
Of course, the information recorded in this intelligence was certainly not exhaustive. It was merely the tip of the iceberg of the many demons, and there were likely more hidden in unknown corners.
After reading it, Xiao Fei stored the jade slip in his spatial dimension.
Before he planned to act against these demons, this intelligence must not be leaked, lest he alert them.
If these demons changed their identities again, it would be difficult to find them.
However, the two hidden within the Dan Xin Sect could be closely monitored now, and perhaps more demons could be implicated.
Xiao Fei tossed one of the lists to the four ancestors of the Lu Sect, letting them handle it while he focused on his cultivation.
As for the other list of those hidden within the Lu Sect, Xiao Fei kept it for himself, as he wasn't entirely confident in the capabilities of these ancestors.
Xiao Fei's cultivation was still at the Golden Core mid-stage. After years of cultivation, he felt he was close to a breakthrough.
For the next period, he declined all worldly affairs and dedicated himself to cultivation.
In terms of elixirs, he directly consumed the best high-grade pills, and his cultivation progressed rapidly.
A year later, when Xiao Fei emerged from his cultivation chamber, his cultivation had reached the Golden Core late-stage.
At this point, he needed to prepare for the next step: condensing the Nascent Soul.
The transition from Golden Core to Nascent Soul was an extremely arduous undertaking.
Back in its prime, the State of Lu had only twelve Nascent Soul cultivators, and they were all only at the early Nascent Soul stage, which was indicative of its difficulty.
The progression from Golden Core to Nascent Soul was related to many conditions.
The foremost was innate talent and aptitude. If one's cultivation aptitude was too poor, reaching the Golden Core stage was already the limit.
It was almost impossible to shatter the Golden Core and form a Nascent Soul.
Coincidentally, Xiao Fei's cultivation aptitude was among the worst. If he wished to condense a Nascent Soul, it would be tens to hundreds of times more difficult than for ordinary people.
Even after he consumed the Wood Element Marrow Cleansing Pill, which raised his Wood Spirit Root to 45 points, among the many high-level cultivators, he could only be considered to have mediocre aptitude.
In addition to aptitude, the assistance of heavenly treasures was also required.
For instance, Huang Feifei, after bathing in ten-thousand-year-old Stone Marrow Milk, directly advanced from the early Golden Core stage to the early Nascent Soul stage.
However, heavenly treasures of this caliber were extremely rare. Even a tiny amount leaked into the cultivation world was enough to cause numerous powerful cultivators to fight fiercely for it.
The scene of many powerful cultivators fighting over Huang Feifei's bathwater in the small world back then was a testament to this.
Xiao Fei currently had no confidence in acquiring such a treasure, nor could he even gather any information about it.
Of course, heavenly treasures required special opportunities or a long time to form. Over the years, they had been used up more and more in the cultivation world.
In the current cultivation world, using such heavenly treasures to condense a Nascent Soul was no longer the conventional method.
Instead, a small amount of spirit herbs with special effects were used to refine the Nascent Soul Condensing Pill.
Although the efficacy of the Nascent Soul Condensing Pill could not match those heavenly treasures that were almost extinct, it served as a strong substitute, providing a way out for later generations of cultivators.
In addition to this, there were also some issues with Xiao Fei himself that needed to be resolved.
The "Primordial Chaos Five Elements Technique" he practiced could only cultivate up to the Golden Core late-stage; he did not have a Nascent Soul stage cultivation method.
Although the Primordial Chaos Ancestor was astonishingly talented, due to limitations in his aptitude or other unknown reasons, he bid farewell to this world after cultivating only to the Golden Core stage.
The "Primordial Chaos Five Elements Technique" he created could only go this far.
If Xiao Fei were to break through to the Nascent Soul stage, he had two options. The first was to switch cultivation methods and cultivate a Wood Element technique. With his current Wood Spirit Root of 45, he should be able to cultivate it.
However, he would have to abandon many of his powerful divine abilities, such as the Five-Colored Divine Light, Primordial Chaos Divine Thunder, and the Five Elements Evasion techniques, as they could not be fully utilized.
This was a painful choice, as difficult to part with as cutting off his own hands and feet.
The second option was for him to create his own cultivation method and supplement the Nascent Soul portion of the "Primordial Chaos Five Elements Technique."
This was also an extremely difficult task.
With his current level, he could create a Qi Refining stage cultivation method, but the higher the stage, the more difficult it became.
A Nascent Soul stage cultivation method was no longer simply about cultivating oneself; it required comprehending heaven and earth, and touching upon the laws of the Great Dao.
This could not be achieved by simply working in isolation.
Besides the cultivation method, Xiao Fei would also face a very serious problem in breaking through to the Nascent Soul stage.
That was the consumption of spirit stones!
Within his body was a dilapidated jade disk, which was the source of his spatial dimension.
The spatial dimension was indeed a good thing, having helped him immensely. It could even be said that it was due to the existence of the spatial dimension that he had achieved what he had today.
Otherwise, with his meager cultivation aptitude of only 20 points, even if he used all his effort, he would have died of old age in the Qi Refining stage.
However, while this jade disk provided him with benefits, it would cause trouble every time he cultivated and advanced.
From Qi Refining to Foundation Establishment, and from Foundation Establishment to Golden Core, it would jump out and absorb spiritual energy profusely to repair the cracks on the jade disk, nearly sucking him dry several times.
However, the benefit was that after the cracks on the jade disk were repaired, his spatial dimension would expand, and his connection with the jade disk and the spatial dimension would become even closer.
To break through to the Nascent Soul stage, he also had to raise a large sum of spirit stones, and the consumption this time would definitely be a colossal amount.
After emerging from his seclusion, Xiao Fei greeted Huang Feifei and, bringing her along, went to visit the other four ancestors of the Lu Sect.
The four ancestors were all veteran Nascent Soul cultivators. If he wanted to condense a Nascent Soul, seeking advice from these seniors would save him a lot of detours.
The first person they visited was naturally Ancestor Shangguan.
He and Huang Feifei both came from the Dan Xin Sect and were now part of the Dan Xin Hall, so they were naturally closest to Ancestor Shangguan.
Ancestor Shangguan listened to Xiao Fei explain his intentions, remained silent for a moment, and then sighed deeply before saying.
"Since the great upheaval, the foundations of our three major sects have been depleted. Now, the entire Lu Sect is penniless. At least our Dan Xin Hall cannot find a single Nascent Soul Condensing Pill.
As for heavenly treasures that can assist in condensing a Nascent Soul, there is not even a trace."
Xiao Fei was not the least bit disappointed by Ancestor Shangguan's answer; he had expected this.
If these impoverished Nascent Soul ancestors had any good items, they would likely have used them long ago.
