After cultivators who practice the Ancient Source Thunder Scripture advance to the Golden Core stage, they need to forge their own special magical treasures.
The spiritual materials required to forge these magical treasures are quite demanding.
This array is used for further refining these spiritual materials to meet the requirements for forging exclusive magical treasures.
This cultivation method has even evolved into another advanced array, which, after a cultivator's body-tempering reaches a high stage, can be used to draw upon the power of heavenly lightning to temper the body.
In addition to these, there are also some offensive and defensive Thunder Derivation arrays.
These arrays can be traditional, large-scale formations covering a wide area.
They can also be miniature array restrictions inscribed on magical treasures to enhance their power, or even their grade.
In fact, this is the primary method of usage.
Upon reading this, Ning Fa understood that the contents of the Thunder Derivation Profound Scroll were essentially all for forging exclusive magical treasures.
The magical treasure recommended in the Ancient Source Thunder Scripture is very special.
It is named the [Divine Firmament Thunder Armor Set].
The reason it is called special is that it is not just a single magical treasure, but a set.
It includes full-body thunder armor and offensive magical treasures.
The most crucial part is the full-body thunder armor.
After cultivators who practice the Ancient Source Thunder Scripture advance to the Golden Core stage, if they wear this thunder armor, they can activate the [Divine Firmament Mysterious Thunder Dharma Aspect] in advance, even if their cultivation has not reached that level.
If their cultivation has reached the point where they can activate this Dharma Aspect themselves, then wearing this thunder armor will further enhance the Dharma Aspect's power and increase its grade.
One can imagine the power of the Divine Firmament Thunder Armor Set and its importance to cultivators of the Ancient Source Thunder Scripture.
However, forging the complete Divine Firmament Thunder Armor Set is extremely difficult, to the point of being nearly impossible.
This is because the requirements for forging this thunder armor are extremely stringent, with the main materials almost exclusively requiring top-tier third-rank spiritual materials, and even including some rare fourth-rank spiritual materials. Most of these are also lightning-attributed, making them even rarer.
Therefore, the Thunder Scripture also mentions not to be fixated on forging the complete Divine Firmament Thunder Armor Set.
One can first forge the offensive magical treasures within the thunder armor set and nurture them as one's life-bound magical treasures, then slowly gather spiritual materials to await the forging of the complete Divine Firmament Thunder Armor Set.
That would require opportunity.
Even Golden Core cultivators, and even Nascent Soul cultivators, might only be able to gather a portion of the spiritual materials in their lifetime.
They would have no chance to forge the complete Divine Firmament Thunder Armor Set, and thus would be unable to activate the Divine Firmament Mysterious Thunder Dharma Aspect to its strongest state.
The power of the Divine Firmament Thunder Armor Set described in the Thunder Scripture made Ning Fa's heart surge with excitement, rendering him unable to contain himself.
But this was something he would only consider after advancing to the Golden Core stage, which was still a very distant prospect.
However, this Thunder Derivation Profound Scroll was still very useful to him now.
For example, if he could master the Thunder-Attracting Essence-Forging Array, it would undoubtedly be of great help to him.
What he valued now was the Thunder Yuan Essence refined by this array, which could be used to forge more powerful Thunder Calamity Beads.
Moreover, it wouldn't affect his own cultivation.
Just imagine, if he had several of these Thunder Calamity Beads in his possession.
Even when facing Foundation Establishment cultivators, he wouldn't need to fear them at all; it was even possible for Foundation Establishment cultivators to suffer an unexpected defeat at his hands.
Furthermore, in addition to this, the Thunder Derivation Profound Scroll also mentioned.
One could condense special Thunder Derivation Talismans and inscribe them onto talismans, refining some powerful lightning-attributed talismans.
Their power would be far greater than ordinary talismans of the same rank.
These special talismans would also be very useful to Ning Fa at his current stage.
Ning Fa calmed his excited emotions, but his brow furrowed slightly.
This was because the Thunder Derivation Profound Scroll only contained a summary introduction; the actual content was missing.
Moreover, it stated that because some Thunder Derivation Talismans were of too high a grade, they were difficult to pass down and preserve.
In reality, many Thunder Derivation Talismans had already been lost.
Along with them, some special arrays could no longer be formed.
For example, the Teleportation Talisman, and the [Lightning Light Teleportation Array] formed by this talisman for teleportation.
Only the most commonly used talismans and related ordinary arrays had been passed down.
Ning Fa couldn't help but feel dejected because he didn't even have these most common talismans now.
It would have been better if he hadn't seen the introduction to the Thunder Derivation Profound Scroll, which only made him desire it in vain, only to get nothing.
But at this moment, Ning Fa's arm felt a sting.
Ning Fa, who had just been feeling dejected, was suddenly filled with surprise.
He then realized that the Thunder Derivation Profound Scroll actually required a separate tracing of its origin.
He quickly activated the scroll.
After a flash of white light on the scroll, the content stunned Ning Fa for a moment.
The scroll was divided into two sections.
One section contained the diagrams of an ancient scroll, which should be the true content of the Thunder Derivation Profound Scroll.
This did not surprise Ning Fa.
What did surprise him was that the other section contained over a hundred tiny talismans of different shapes and forms.
More than twenty percent of these talismans were lit, indicating they could be traced immediately without consuming extra energy.
The majority of the remaining talismans were dim, meaning they would require energy to be traced.
Ning Fa touched some of the talismans with his divine sense and got a general idea of the cost required to trace them.
Almost all of them required some of the scroll's energy, with varying amounts.
The least demanding only needed a few percent of the energy from the mysterious patterns, while the more demanding ones could require several tens of percent.
The most outrageous was the [Teleportation Talisman], which required the energy of an entire mysterious pattern.
This left Ning Fa dumbfounded.
Clearly, the more energy a talisman required, the higher its grade.
Ning Fa understood that talismans of such grades were far beyond his current reach.
He estimated that they would require the Golden Core or even Nascent Soul realm.
Ning Fa first traced the Thunder Derivation Profound Scroll, which didn't require energy, and over twenty Thunder Derivation Talismans.
He took a rough look and found that these talismans were the most commonly used ones.
They included the talismans he needed for the Thunder-Attracting Essence-Forging Array and for refining some low-level Thunder Derivation Talismans.
Ning Fa briefly scanned the main text.
He discovered that constructing the formations described in the Thunder Derivation Profound Scroll was no easy feat.
It required completely comprehending all sorts of basic talismans.
And that was just the most fundamental part.
The next step was to combine and construct various talismans, which was even more troublesome.
The more talismans there were, the more variations and the greater the difficulty.
Some high-level formations required connecting and combining hundreds of thousands of different types of Thunder Derivation Talismans.
The difficulty was imaginable.
Interestingly, cultivators could freely experiment with different talismans.
It was highly possible to construct unique formations.
The freedom was immense.
It was even possible to create formations more powerful than those listed in the Thunder Derivation Profound Scroll.
However, this not only required time but also a great deal of talent.
Reading this, Ning Fa once again marveled at the profoundness of the Thunder Derivation Profound Scroll.
He even had a faint feeling that the value of the Thunder Derivation Profound Scroll might not be lower than the Ancient Source Thunder Scripture itself.
If formation masters obtained this Thunder Derivation Profound Scroll, they would likely be overjoyed.
Ning Fa tentatively began comprehending a few of the most basic talismans.
This process took several days.
Ning Fa had to stop.
His expression turned somewhat grim.
The comprehension of the talismans was not going smoothly. Based on his insights over the past few days, he estimated that comprehending a single talisman would take at least several months.
