Sure enough, after listening to Xia Duo's words, Nia became full of energy.

The simple test on the regular nature of the equation spell Xia Duo was basically completed, and he was not ready to continue to wait for the subsequent changes, he was going to conduct a destructive test.

Of course, since his understanding of the equation spell is still very limited, what he is really going to do is to first dismantle or erase the existence of this spell "more scientifically" within the scope of his own understanding.

In this regard, although Nia is curious to know how long this spell can last, she also expresses her willingness to support Xia Duo's actions.

After all, if you can cast this spell once, you can cast it many more times.

The two of them have decided to return to the Tower of Time and set up an Equation Spell Observation Room, which is dedicated to long-term observation of the retention time of Equation Spells, as well as the changes that may occur during this period.

As for now, it's better to erase this outside spell as soon as possible.

……

Ask, how do you undo an equation spell?

The first thing that came to mind was to hedge against the current form of counter-operation, which is commonly referred to as "spell counter-action".

Despite the goal of erasing spells, Xia Duo didn't want the process to be too simple and crude, and there was always something to be paid off.

The first attempt was made by Niya, which could be regarded as a chance for her to "take revenge", and Xia Duo stepped aside to take care of it after adjusting the status of the equation spell to the normal [Light Technique].

The Luminosity is simple to cast, and the so-called reverse operation is only relative to the Magic Net String Shock state in the spell element, in fact, if you don't consider the counter target, this is actually a Luminous Spell.

Using the case on the earth as an analogy, it is almost similar to the principle of noise cancelling headphones, using inverted sound waves to cancel out the sound waves of normal phase to achieve the purpose of noise reduction.

But in fact, whether it is forward or inverse, the human ear cannot hear any difference.

The Wizarding World's spell counters are similar, and one thing that's as true as noise-cancelling headphones can't cancel out some of the sound waves is that the caster doesn't actually have the exact same spell casting details as the target spell in practice.

However, as long as the key elements of the target spell are neutralized, it can basically be considered that this countermeasure is qualified and effective.

[Light Technique] is basically the first spell that every apprentice comes into contact with and learns, and there are only 12 elements in the 0 ring state, which can be called the simplest spell except for [Magic Trick].

In Xia Duo's view, [magic tricks] cannot be called a complete spell, it is just a combination of discrete elements, and what effect it can have depends on the caster's own mastery and application of spell knowledge.

Weak, it may just make the fingers shimmer; Strong, it can even be used as a normal spell, which is an unconventional spell with a high upper limit and a lower limit.

In order to erase such a simple [Light Technique], in Nia's past cognition, there was no need to even use countermeasures, and it was enough to destroy one or two key elements alone to make the spell ineffective.

Even, as long as you wait a little longer, the spell will naturally dissipate due to the self-recovery trend of the magic net.

But now, the so-called "equation spell" once again subverted Nia's cognition, and after a very complete countermeasure process, the target spell was only the string of the magic net that constituted the source of the spell and shook slightly, and the rest was not affected in the slightest.

Although Nia had expected the result before casting the spell, the near-ineffectual result was something she had never imagined.

Seeing this scene, Xia Duo couldn't help frowning, to be honest, this was also beyond his expectations, so he greeted Nia again, "Try it again." ”

Niya tried again as she said, and it was still a very complete countermeasure process, with a total of 12 spell casting elements, and with Niya being the basis for spell casting, it was impossible to make a mistake at all.

If the target spell was a normal [Light Spell], it would have been canceled out long ago.

But now, the second countermeasure was still ineffective, and this time, Nia didn't wait for Xia Duo to say hello, and she tried a few more times without giving up.

The results are obvious, not a single one of them has been able to take effect.

Xia Duo thought about it, adjusted the equation spell to a 1 ring spell, and asked Niya to try again, but the result was still unable to be countered, and then 2 rings, 3 rings, and all the way to 8 rings, and the result was still the same.

Later, Xia Duo didn't try again, he speculated that this spell had a deeper structure, hiding the magic network environment, and the source point of the spell it showed was just the appearance derived from the real core.

This speculation is not unfounded, this spell is what he casts, and the number of elements it consists of is the most spell he has mastered, but most of those elements are not manifested in the source of the spell after the spell is completed.

Instead, it has to be controlled by another discrete web string, which can make the spell source more complex, or simpler.

"I think I've seen this scene somewhere!"

Xia Duo traced his memories and soon found a similar feeling in the princess's ascension ceremony, when the spell cast by the princess did not exactly correspond to the source of the spell, but produced a subtle change that affected the background fluctuations of the magic net in a considerable area.

This kind of change, when the caster is first encountered, will only ignore it as a fluctuation in the background of the magic web, but Xia Duo has gone through several ritual rehearsals, as well as formal ceremonies.

And also got the original version of the elf's ascension book, although the ceremony with the princess does not match in many details, but in general you can still see some clues.

The subtle changes in the background fluctuations of the magic net in the princess ceremony seem to be chaotic and no different from background fluctuations, but in fact, there are traces of its changes.

So, will this equation spell also have a lot of "changes of change" hidden in the background fluctuations of the magic web?

The fluctuation of the background of the magic net, which is essentially the oscillating state of the strings of the magic net, can also constitute a spell element, and it is inconspicuous.

Xia Duo had vaguely thought of this stubble before, but he focused more on its independence that was extremely similar to the Lost Lock, thus ignoring the true "ontology" hidden by this equation spell.

Then, Xia Duo first observed the magic net from a macro perspective, and found that this spell could indeed affect the macro magic web.

If the effect of the Mystery Lock is a line or a plane, then the effect of this equation spell is just a point.

Its impact on the macroscopic web is almost negligible, although this is only relative to the Lost Lock.

For a normal spell, a little bit beyond the norm is enough to give it a trait that is far beyond that of a normal spell.

Then, Xia Duo re-examined the microscopic magic net strings around him, starting from the special magic net strings used to control the equation spells, and explored and peeled off the cocoon little by little.
