Chapter 1595: Equation Spell

While accompanying Niya in her studies, Xia Duo was also reorganizing his own knowledge system. As the saying goes, "reviewing the old leads to understanding the new," and in this process, his understanding of Netheril Magic was becoming increasingly profound.

And today, after completing the update of Niya's Knowledge Star Chart, Xia Duo, while cross-referencing the star chart, once again had an idea that he had entertained long ago—

"What exactly are the rules of Magic?"

Xia Duo knew many principle-level Magic Theory concepts, such as the essence of Element-Matter being the same, Spell Construction (phenomenological existence), the essence of the Magic Net, the invariance of Magic, and so on.

But these were mostly laws summarized from phenomena; if a special case were to appear one day, the law would be broken, and a new one would need to be found.

As for others, more specific conclusions derived from these existing laws that were very clear and almost impossible to overturn, Xia Duo called them "laws."

Such as the single-string transformation law of the Magic Net String, the Spell Construction Law (Element Expression Law) within a Plane, and so on; almost every Spell Element could be called a law.

And delving deeper from these laws leads to specific Spells. Xia Duo believed that Magic and science were essentially the same thing, but this was where their greatest difference in manifestation lay.

On Earth, the formulas used to express laws and theorems themselves have no practical ability to interfere with reality, but in this Magic world, laws and theorems themselves can directly interfere with reality.

Then, continuing to delve deeper, does there exist a summary law for a specific direction?

The answer is yes.

On Earth, this might be called an "XX Equation," such as the famous Maikesuoweifangcheng; but in the Magic world, what would the specific manifestation of an Equation be like?

Various theories below the principles in the Magic world almost all have their Spell expressions, so what about Equations?

Does there exist a special Spell capable of fully manifesting the entirety of a certain law, whose manifestation is closer to the imagined source of Magic?

Xia Duo believed there was; it was just that the past him could not see the full picture of Magic—although the current him couldn't either, at least he had realized the possibility of the full picture's existence.

Through this opportunity to study with Niya, Xia Duo reorganized his entire knowledge system and became even more convinced of the existence of Equation Spells.

And he already had a certain grasp of the derivation process for one such equation!

……

After arranging Niya's next stage of study plans and test sets, Xia Duo slipped into his own subconscious world to conduct purely theoretical derivations.

In fact, if the equation he chose hadn't been on the verge of being discovered, he wouldn't have been able to conduct purely theoretical derivations in his consciousness without needing various experiments in reality.

The Evocation Equation was the first one Xia Duo thought of.

First, it is sufficiently fundamental, or rather, sufficiently simple, only involving the transformation of basic elements and energy;

Furthermore, Evocation Spells are also a type of Spell that Netherese Mages study extensively, belonging to a branch of the Creation School, with plenty of related theories and data (Spells), so there is no need to design additional new experiments to supplement the data.

Other Spells are different; either the category is too broad and data accumulation is insufficient, or a more specific classification cannot be found.

In fact, Xia Duo wanted to obtain an Equation Spell for the state of matter, which would mean he could perform more precise and even exquisite operations on matter.

It is just that this category is truly too large. What is called the state of matter—does size count? Does weight count? Does composition count?

With various variables mixed together, given Xia Duo's current self-perception, he did not believe he could complete the derivation of an equation for the state of matter.

It would be better to settle for the next best thing and derive the "Evocation" Equation Spell, which seems not very useful, but in reality, might truly not be very useful either.

……

Tower of Time, top-floor Study.

Beside the Projection Window, Niya was writing furiously, occasionally casting Spells to calculate, while Xia Duo looked as if he were asleep, completely unconcerned with the movements of the outside world.

Not knowing how much time had passed, Niya suddenly stopped the pen in her hand and reached out to wave it twice in front of Xia Duo. Seeing that Xia Duo did not react, she let out a long sigh of relief.

Throwing the pen aside, she leaned heavily against the back of the chair, just about to adjust the content displayed on the Projection Window to relax, but she did not expect that the next moment, Xia Duo would suddenly open his eyes.

Their eyes met, Niya smiled awkwardly, moved her body slightly away from the chair back, and picked up the pen, preparing to continue answering questions, but Xia Duo smiled slightly, took the initiative to change the content of the Projection Window, and said:

"Rest for a while! You should rest after doing problems for such a long time."

"Oh, okay."

Niya hurriedly put down the pen, moved her chair to Xia Duo's side, and after sitting down next to him, she glanced at the scene of Daxia Territory residents pioneering outside the window before asking:

"About how many more test papers do I have to do?"

Although Niya did not deny that her progress had been rapid during this period, she had never experienced such high-intensity study before, and even after trying to adapt for a period of time, she still felt a lot of pressure.

The reason she was asking this now was not because she wanted to back down, but because she wanted to have a clearer understanding of the subsequent study plan.

To this, Xia Duo's answer was—

"Learning is endless, and the test papers will never be finished, but this stage of study does have an end. According to your current efficiency and progress, you only need to do about as many test papers as before, and it will be over."

"Ah—there are still that many!"

Niya elongated her tone, looking pitifully at Xia Duo, but in the end, she did not say anything about giving up, instead asking: "Then will you always be with me?"

"Of course, just like now, I will always be with you."

Xia Duo's words gave Niya great encouragement, and with the goal now visible and tangible, she was once again full of energy.

After sitting next to Xia Duo for a while, Niya moved her chair back, picked up the pen again, and began to answer the questions seriously.

Seeing this, Xia Duo adjusted the Projection Window to the Weilan sky, then used the Detection Field of the Projection Window to cast a Spell, extending his own Perception Field. In an instant, his perspective split into two—

One was still in the Tower of Time, with Niya seriously doing problems opposite him; the other was already high in the sky, with the bright red sun overhead and the Daxia Territory residents still working hard to pioneer below.

Xia Duo was no longer a stranger to casting Spells with the help of the Perception Field, but this time the Spell he wanted to try casting was somewhat special. After the Perception Field circled above the Territory, it quickly Yaoyue toward the south.

……

At the foot of Wolf God Mountain.

After many years, traces of the Orc tribe living here still remained, but most of the stone buildings had already been covered by overgrown trees and vines, appearing somewhat desolate.

If he hadn't known about it beforehand, Xia Duo would have thought this was some ancient civilization ruin.

He sighed to himself, then began to cast the Spell.
