Xia Lin's main purpose in selecting these books was to find a way to solve the rune switch and promote the three rings, and the focus of these books was naturally biased towards these two aspects.

For example, the ancient mages' primitive rune research notes, although the ideas are a little simple, but there may not be no merits in them, the so-called stones of other mountains can attack jade, Xia Lin wants to see if he can find other feasible ideas from the theoretical basis of runes.

In addition to these rune research notes, the rest of the books he selected were related to the plastic energy system and illusion spells, among which there were also quite rare three-ring fireball spell rune disks and spell scrolls, with the help of which Xia Lin was able to familiarize himself with the spell model for recording fireball magic.

As for the illusion spells, Xia Lin is interested in them for personal reasons, although there is an illusion department in the Royal Academy of Magic, but the illusion spells are generally difficult to learn except for the simplest zero ring shimmer technique.

Most of the zero-ring spells in other spell systems can be built with two runes, and the zero-ring spells in the illusion system other than the shimmering spell, such as the secondary phantom, require four runes to complete, and there is an additional set of template runes composed of structure runes and shape runes than other zero-ring spells.

The other two spells of noise and courage are also composed of four runes, plus these spells are not of much use on the battlefield, and they are not on the list of required spells for sergeants, Xia Lin is actually completely unfamiliar with this spell system in addition to knowing the basic runes of illusion spells.

Taking advantage of this opportunity, Xia Lin wanted to learn more about the illusion spells, and see if he could use these spells to realize some of the ideas he had accumulated before, such as recording images and sounds through illusion spells, and making things like video recorders and projectors, so as to enrich the media communication forms of this world.

Soaking in the library, he studied the various spell notes left by the people a few days ago without paying attention to what was going on outside the window, and benefiting from the intelligence that gradually increased with the improvement of his mental power, Xia Lin quickly went through the content related to the study of runes and the construction of the three-ring spell in the more than sixty books he had found.

However, in addition to learning a lot of tips for casting spells, he has enhanced the flexibility and adjustability of his spells, faintly understood some of the functions of template runes that are common in various spells, and learned the difference between three-ring spells and two-ring spells, but he didn't gain anything.

As a set of runes that are ubiquitous in all kinds of spells, template runes have a huge variety and quantity, which constitutes the biggest obstacle for mages to study runes and magic, and in the past few hundred years, there are naturally many amazing and brilliant mages who have studied and transformed them.

Unlike other runes that cannot change the position of the spirit power node, by changing the variable spirit power nodes of the structure rune and the shape rune, the form of the spell will also change after it takes effect, and in the process, the mages have the ability to DIY the form of the spell effect they want.

For example, in Audlan's Spell Notes: Mage's Hand, there are four ways to form different forms of Mage's Hand by subtly changing the Mage's Hand template, the rune group's mental power nodes.

It turned out that the mage hand made by Xia Lin only had a square palm and a cylindrical thumb, and its flexibility was very poor. Through these techniques, Xia Lin mastered the transformation of the mage's hand into a five-fingered palm, and even the mage's hand in the shape of a hook, a long stick, or a tray depending on the situation, to cope with different occasions.

The five-fingered palm is always much more flexible than the original simple geometric structure, and Xia Lin can be regarded as a big gain, as for the other gain, it is not particularly useful.

By comparing the spell models of the two-ring scorching ray and the three-ring fireball spell, Xia Lin found that the biggest problem that the three rings are difficult to break through is that in the three-ring fireball spell model, the number of fire rune groups as the core of the spell model has been increased from three to five, and a special rune group module has been added.

The rune module consisted of five runes, which looked quite complex, but after Xia Lin carefully identified them, he found that this rune group was composed of soul runes, isolation runes, template rune groups, and a rune that he looked a little familiar with.

After carefully comparing the general shapes and coordinate data of the various runes recorded in his mind, Xia Lin found that this rune was actually a new rune transformed from the spiritual power simulation rune that constituted the communication technique.

This new rune had never been seen in Xia Lin's previous research, could it be that this was the reason why the difficulty of learning the three-ring spell compared to the two-ring spell had skyrocketed?

Xia Lin, who was a little concerned about this discovery, found several rune disks and spell scrolls of the three-ring spells such as lightning balls, shield techniques, and flying spells in the library, and sure enough, he also found this set of rune modules in it, obviously, this newly discovered rune module of Xia Lin is indeed the uniqueness of the three-ring spell.

However, what kind of role this set of rune modules played in the three-ring spell, Xia Lin was a little puzzled. Soul Runes, Isolation Runes, Template Rune Groups, and a new Rune that simulates the transformation of the Spiritual Power Rune can't be put together.

Writing down this question in his notebook and preparing to go back to his research institute for research, Xia Lin continued to read some books on spells related to the illusion department, and to Xia Lin's surprise, he actually found the new rune transformed from the spiritual power simulation rune in the noise technique of the zero ring of the illusion department.

This new rune, along with the template rune group, forms a rune module in the Noise spell model, and is clearly a pivotal role in the effectiveness of noise.

Surprised, Xia Lin hurriedly found other books related to illusion spells from the bookshelf, but the result was thought-provoking, spells such as secondary phantoms, shimmering magic, silent illusions, friendly spells, and strong light spells did not have this unique rune module composed of new runes, and in spells involving sound such as noise, phonograph, and loud sound, Xia Lin found this rune module.

"So this new rune is a rune related to sound?"

Xia Lin closed the book "The Making of Alchemy Phonographic Crystals", and naturally had some conjectures about the effect of this new rune.

The spell configuration of Zero Ring Noise is two Kinetic Runes with this new rune and template rune, and the First Ring Gramophon adds an additional save rune and a template rune group, and the rest is the same as the noise model construction.

Starting from the principle of sound generation, the kinetic rune should play a role in these two spells to make the particles move, so what is missing in this link?

Xia Lin quickly confirmed the effect of this rune, that is, to cooperate with the template rune to make the particles produce a more complex vibration behavior than directional movement, so as to create sound!
