After finishing up, Xia Duo summoned Ta Ling, "In the past two days, has the energy reserves of the Tower of Time risen or declined?" ”

"Acting Xia Duo, the energy reserves of the Tower of Time have increased by 0.5% overall in the past two days!"

"Whew-"

Xia Duo breathed a sigh of relief, it seemed that the previous adjustment of the management method of the spell practice room was still fruitful, reversing the trend of negative growth in the energy reserves of the Tower of Time in one fell swoop.

Of course, the situation is still not optimistic, and it only rose by 0.5% in two days, which is indeed a bit slow, even if you don't think about the future, the transformation of the spell laboratory is still imperative.

Thinking of this, he didn't rush out to have a look, but leaned back in his chair and began to recall the content of "Research on the Mutual Elimination of Field Interference in the Suppression of Superposition Spells".

Almost as soon as he had a memory, a paper from the library of the Second Academy of Magic of the [Projection Plane: Arcane Empire] appeared in his mind.

Now, of course, he doesn't need to look through the notes he used to have, and of course, the notes are now lent to Nya by him, and he can't even look through them.

However, by retrospectively remembering it, he was able to directly recall the original paper he read in the projection plane, and in fact, there were still many errors and omissions in his later notes, so it was better to recall the original directly.

It is more convenient and comprehensive, after all, in addition to secretly recording in the carry-on space at that time, it was only an excerpt, how could such a large library be completely copied in a short period of time.

Even, at that time, he mainly copied the title of the book, rather than the content, the title or the table of contents, which can provide many research directions, which is the most important object of Xia Duo's transcription.

Thinking about it now, he almost regretted his intestines, and if he knew that he would be able to trace his memories later, he should have ignored nothing at that time, at least turning over all the books.

That way, he would now have a portable library with a collection far beyond the Tower of Time.

It's a pity that time can't be reversed!

Of course, if he could turn back time, a library would be a long time away!

Considering his current ability, Xia Duo once again included the projection plane in the plan, after all, it would not take much time just to go and gather knowledge.

If you encounter a projection plane with a certain basic research facility like the [Arcane Empire], it is not impossible to conduct research in the projection plane.

The only drawback is probably that the projection is the projection after all, and I haven't been able to touch the deeper magic net in the main plane, so it can't be shown in the projection plane, and of course there is no upgrade.

Therefore, it is particularly important to withdraw in time, and of course, if there is a great benefit, you can also consider staying for a while.

……

The so-called "superposition spell suppression field interference" is a phenomenon discovered by the arcanists of [Projection Plane: Arcane Empire], that is, two or more spell suppression fields will affect each other when they are in a superimposed state.

The so-called "mutual growth and negation" is the different result of this superimposed effect, either strengthening the spell suppression effect in a certain area, or weakening, of course, it may not change.

A new type of spell laboratory born on this basis can dynamically adjust the intensity of suppression by changing the interference state of the superimposed spell suppression field.

Like the current spell laboratory of the Tower of Time, although the spell suppression field inside it is also multi-level, at the same time, unless there are multiple spell sources in the laboratory, there will only be one spell suppression field.

In other words, if there are multiple spell sources at the same time, there will be multiple spell suppression fields stacked in order to smooth out the effects of these spells.

This may seem more energy-efficient than the Arcane Empire version, and you can use as many spells as you can, but that's not the case.

In the paper that Xia Duo recalled, it was mentioned that the Arcane Empire originally used a more modest version of the Tower of Time.

But later, almost all of them were replaced with a dynamically adjusted version.

The key to this is that-

The energy consumption of two or more low-level spell suppression fields is lower than the energy consumption of one high-level spell suppression field.

The Arcane Empire version uses the "superposition state interference to grow and grow", which produces the effect of a high-level spell suppression field through multiple low-level spell suppression fields.

This is a bit similar, the original scale used a gold scale, but now it is replaced by several iron scales, the effect is almost the same as before, but the price is much cheaper.

……

Xia Duo had not been in contact with the study of field interference before, but it did not prevent him from starting now, and he was even quite familiar with it:

"It's the same as 'the low-ring expression of high-ring elements'!"

From the perspective of resource utilization, field interference is undoubtedly more valuable and practical than the low-loop expression of high-loop based on resource accumulation.

However, "low ring expresses high ring" is like a bunker bomb shelter in peacetime, which is really impractical, very simple and rude, and has low resource utilization, but it can really play a huge role at a critical moment.

For example, the Tower of Time was attacked by an elven high mage before, and the elven mage transformed the ruins of the Lost Lock, forcibly blocking the link between the Tower of Time and the deep magic web on a large scale.

If there is no de-escalation procedure, the low ring is used to express the high ring, and the highest combat power of the 11 rings is maintained, and the Tower of Time is estimated to have been breached long ago.

The biggest difference between field interference and low ring expression and high ring is not at the application level, or at the resource consumption level, but in -

"The Sword Comes"

The latter is the higher ring, which is an equivalence relationship and is related to the deeper magic web, while the former is only similar to the higher ring and is not related to the deeper magic web

This also means that there is a so-called "spell extreme effect", or that the upper limit of the energy level that Xia Duo used to think that a spell can reach at a certain ring level is not really the upper limit, and it can be higher.

It's an interesting subject, but Shado isn't ready to start working on it right away.

Although he has made some adjustments to his future plans because of the emergence of memory retrospective ability, it is more of a medium- and long-term or global adjustment.

Specifically, in the near term, except for the sudden event of renovating the spell practice room, there is no need to adjust the original plan.

……

After thinking about it, Xia Duo contacted Nia, "Have you read the notebook I gave you?" ”

Almost as soon as he summoned him, Nya replied, her tone full of joy, surprise, and a hint of excitement:

"Look, that research paper on field interference is really wonderful, more than any magic book I've read at the Giles Tower, it's-"

Nia was a little speechless for a moment, and repeated it twice without saying the rest of the sentence.

Xia Duo added to her what she had to say later, "It has to be more concise and rigorous, right?" ”

"Hmm." Nia replied heavily.

Compared with the various travelogues, biographies, and conversational magic books on the main plane, research papers that eliminate irrelevant information from the projection plane will undoubtedly be more in line with the taste of the arcanist.

Xia Duo didn't say anything about this, he contacted Nia just to make up for the missing in the paper, after all, he had saved a lot of content when he used his personal space to transcribe.
