Ning Fa slapped his thigh, overjoyed.
He hadn't guessed wrong after all; this Mysterious Scroll had indeed traced back another cultivation technique from the Yuan Lei Jue!
Judging by its appearance, the Yuan Lei Jue was derived from this Ancient Source Thunder Scripture. Just the name itself sounded far more advanced than any so-called Yuan Lei Jue.
As Ning Fa's excitement surged, the Ancient Source Thunder Scripture on the scroll transformed into a stream of white light and flew into his forehead.
Ning Fa couldn't help but close his eyes.
A full hour later, Ning Fa opened his eyes, lingering excitement and shock still in them.
This cultivation technique only had the general outline and the first six levels, allowing cultivation up to the late Foundation Establishment stage. Only cultivators with Lightning Spiritual Roots could practice it.
It seemed the Mysterious Scroll's energy was insufficient, preventing it from tracing back the later stages of the technique.
However, being able to cultivate to the late Foundation Establishment stage was enough for Ning Fa for now.
After a brief perusal of the general outline, Ning Fa was mostly certain that the Yuan Lei Jue he had practiced before was a simplified version of this Ancient Source Thunder Scripture, as there were significant similarities.
For instance, the meridians and acupoints involved in the Yuan Lei Jue were all present in the Ancient Source Thunder Scripture. However, the Ancient Source Thunder Scripture required several times more meridians and acupoints to circulate its energy.
Judging solely by the description in the general outline, this cultivation technique was terrifyingly powerful, even making Ning Fa suspect it might be exaggerated.
Although the cultivation technique didn't explicitly state its tier, Ning Fa felt it was at least mid-grade Earth Tier.
Even Earth Tier felt too low; this technique had a high probability of reaching Heaven Tier.
Firstly, this cultivation technique was a rare Dual Cultivation of Body and Law technique, which not only cultivated spiritual power but also physical strength.
The technique explained that this was because the technique was too overbearing, placing extremely high demands on the cultivator's physique. Without a corresponding physical realm, it was difficult to execute the technique, and many of its secret arts and moves required robust physical support to be performed.
Ning Fa had heard a little about the path of Dual Cultivation of Body and Law.
In the current cultivation world, the mainstream was Law Cultivation. There were also a small number of Body Cultivators, and even fewer cultivators who walked the more difficult path of Dual Cultivation of Body and Law.
Cultivators who followed the path of Dual Cultivation of Body and Law generally possessed strength far exceeding that of cultivators of the same level, and could even contend with opponents across different realms.
However, their cultivation advancement was also extremely difficult, especially since body refinement demanded even more cultivation resources than Law Cultivation.
In ancient times, many cultivators chose the path of Dual Cultivation of Body and Law due to its formidable power.
But with the decline of spiritual energy and the scarcity of heavenly treasures, Body Cultivation gradually waned, and cultivators practicing Dual Cultivation of Body and Law became even rarer.
However, the Ancient Source Thunder Scripture began requiring body refinement from the second level, corresponding to the mid-Qi Condensation stage. If the physique did not improve, the meridians and acupoints would be difficult to expand, and spiritual power would advance slowly.
Therefore, each level of the Ancient Source Thunder Scripture had a corresponding body refinement chapter.
Another point was that the Ancient Source Thunder Scripture had the concept of a Thunder Source.
As for the Thunder Source, Ning Fa's own understanding was that it was a repository for spiritual power, similar to the Dantian's Sea of Qi.
However, the special aspect of the Thunder Source in the Ancient Source Thunder Scripture was that it could have more than one.
In addition to the Main Thunder Source in the Dantian, Lesser Thunder Sources could be opened up in other parts of the body.
Each Lesser Thunder Source opened up could increase the cultivator's total spiritual power by several times.
This way, if a cultivator practicing the Ancient Source Thunder Scripture opened up multiple Lesser Thunder Sources, their total spiritual power could potentially be several times that of cultivators of the same level.
Furthermore, because Lesser Thunder Sources were generally opened up at important acupoint nodes within the meridian circulation, when a cultivator circulated the technique, they wouldn't need to draw spiritual power from the Dantian. Instead, they could directly use the nearest Lesser Thunder Source to provide spiritual power.
This naturally allowed for a significant increase in the cultivator's casting speed, which was extremely crucial in the ever-changing battles between cultivators.
However, opening up Lesser Thunder Sources was not that simple.
The technique stated that most cultivators who practiced it could consider it good if they managed to open up three or four Lesser Thunder Sources before Foundation Establishment.
Moreover, it was best to open up Lesser Thunder Sources during the Qi Condensation stage. If one attempted it after reaching Foundation Establishment, opening up a Lesser Thunder Source would become extremely difficult.
This was because each Lesser Thunder Source had to establish a close connection with other Thunder Sources, and this process was easiest during the Qi Condensation stage.
Therefore, for a cultivator with a Lightning Spiritual Root who practiced the Ancient Source Thunder Scripture, their potential could be gauged by how many Lesser Thunder Sources they could cultivate during the Qi Condensation stage.
In ancient times, some cultivators with Lightning Spiritual Roots even deliberately delayed their Foundation Establishment to open up more Lesser Thunder Sources.
The more Lesser Thunder Sources one had, the more solid their foundation would be. Not only would they have a higher total spiritual power, but breaking through to Foundation Establishment would also be relatively easier.
With the Ancient Source Thunder Scripture being so powerful, being a formidable Dual Cultivation of Body and Law technique and possessing the unique cultivation method of Lesser Thunder Sources, it allowed cultivators to far surpass their peers in strength.
This naturally came at a price.
That price was that cultivators practicing this technique had significantly slower cultivation advancement compared to other cultivators.
It had extremely high requirements for cultivation resources, such as the concentration of Spirit Veins; even a third-tier Spirit Vein could only be considered barely adequate.
The first-tier high-grade Spirit Vein where Ning Fa was currently located was naturally far from sufficient.
Even though his sensitivity to Thunder Spiritual Power was far greater than before, the sparse spiritual energy concentration severely restricted him. Even Ningchang Island, with its second-tier high-grade Spirit Vein concentration, seemed insufficient.
Ning Fa gradually calmed down, a flicker of hesitation in his eyes.
Although the Ancient Source Thunder Scripture appeared very powerful, it seemed very difficult to cultivate, especially while walking the arduous path of Dual Cultivation of Body and Law.
Moreover, this Mysterious Scroll seemed to have insufficient energy, only tracing back the first six levels of the Ancient Source Thunder Scripture. He didn't know if the subsequent levels could still be traced back.
This made Ning Fa hesitate somewhat.
But after a moment of thought, he made up his mind.
He currently had no other options. The Ancient Source Thunder Scripture was likely the highest-tier lightning cultivation technique he could access.
Especially with the existence of the Lesser Thunder Source, it should be able to solve the problem of his Great Five Elements Thunder Body's high demand for total magical power.
Given the powerful boost his Great Five Elements Thunder Body provided for cultivating lightning-attribute techniques, practicing this one should not be an issue.
As for the fact that this technique only had the first six layers, only allowing cultivation up to the late Foundation Establishment stage, that wasn't a major problem for him right now.
As long as he could advance to the Foundation Establishment stage, with his Mysterious Thunder Body and the Ancient Source Thunder Scripture, he was confident he could wreak havoc among Foundation Establishment cultivators, which was more than enough.
The only potential constraint might be the body-refining portion.
However, the Ancient Source Thunder Scripture also came with accompanying body-refining potions. With these potions as assistance, they could accelerate the body-refining progress.
Although the spiritual materials required for these body-refining potions appeared very rare, once he grew stronger, he should have a chance to obtain them.
If nothing else, as long as he could advance to the middle Qi Condensation stage, relying on that Mysterious Scroll, he was confident he could quickly advance to become a mid-grade Pill Master.
At that time, his power and status within the clan would undoubtedly increase greatly, and finding ways to obtain these resources should not be a significant problem.
Having figured this out, Ning Fa couldn't help but smile.
Today had been a huge harvest. Not only had he uncovered the secret of his own body, but he had also obtained this ancient lightning cultivation technique.
It gave Ning Fa a feeling of destiny, as if everything was guided by fate.
Ning Fa didn't rush to start cultivating. The shock he had received tonight was too great, and his mind was in turmoil, making it unsuitable for cultivation.
He lay down directly on the futon, thinking about the introduction to the Great Five Elements Thunder Body on the Heavenly Mechanism Scroll, and gradually drifted off to sleep.
