Drawing circles and carving runes is a highly technical job, and as a product unique to this world, it is not just a simple "painting" as many people imagine - although it is indeed simple to simply draw according to the original map, but to become a rune master, you can't just learn to draw.

If you simply draw a circle according to the drawings, then ordinary people can do it, even civilians who can't sense magic at all, as long as they are told how to draw and what to draw, they can do the drawing of the circle, which is a simple "production and copying" work.

But in addition to this kind of production and reproduction, rune masters also have the ability to create and improvise: they need to help mages make magic props, or draw magic circles on various complex magic guide materials, and each magic item or magic guide material has different properties, and the combination has countless variations, which dooms them to not be able to draw magic circles completely according to the drawings in the book - they must change the arrangement of the runes on the magic circle according to the different carrier materials and the use of the magic circle, Or fine-tune the position and connection of each rune.

In short, runemasters create "blueprints", and every time they draw, they are drawing the original mother and are creating.

And this process requires the ability to perceive magic and the ability to "tune" the runes.

The former can determine whether each rune will function properly during the blueprint process and sense whether there is any interference between the runes that exceed the threshold, while the latter is a skill that injects its own magic into the runes and tests them - although the rune master often does not have the ability to drive the entire circle, it is still possible to test a partial rune group.

In order to achieve these two things, you must become at least a first-level official mage, and it is absolutely impossible for a mage apprentice to do it, because mage apprentices do not have the ability to sense and manipulate multiple runes at the same time, and their magic power cannot be accurately controlled and exported to the outside world, if they do...... And they graduated.

And Jenny's profile clearly states that she is a mage apprentice.

This time Jenny heard Gawain's question clearly, but she didn't know how to answer, and after hesitating and weighing for a long time, she chose to lower her head and whispered: "It's luck, my lord." ”

"Luck?" Gawain raised his eyebrows, his tone disapproving.

"Yes, luck," Jenny still kept her head down, "I have a good instinct, I can always find the right way to arrange the runes, you should know that there is a certain pattern in the arrangement of runes, as long as you have enough experience, plus enough intuition, you can accurately arrange those ......"

"If it's really lucky, you'll die in an accident before you can accumulate enough experience," Gawain interrupted the other party directly, "Although I am a knight, I also understand the basic principles of magic - for a magic array, the position and connection of each rune is quite strict, unless you have an insight into the laws of all the runes in the world and how they are combined, you can't arrange each of them in place." There is indeed a pattern to the arrangement of runes, but I have never heard of anyone who has analyzed the arrangement of all runes, and it is precisely because humans cannot parse every combination of runes that they need the ability to 'sense' and 'tune'. ”

Gawain said, staring at the silver-haired girl in front of him: "Raise your head and be honest with me - how do you know where each rune should be placed and what effect each rune will have when you can't perceive and tune it?" ”

Probably because Gawain's tone was too serious, so that Jenny couldn't help but shudder, and even more daring to speak, Hetty saw this and remembered the role that Gawain told him before, one strict and one lenient, so he said in a soft tone: "You don't have to be nervous, this is not a royal capital with strict rules, nor is it a dull and old-fashioned secret festival, we welcome and encourage all behaviors that can work on the construction of the territory, even if this behavior is deviant." ”

Jenny finally raised her head and looked in Gawain's direction, while the latter nodded slightly with a serious expression: "I can assure you that creative ideas are protected here, because I am the law of the land. ”

"Actually, it's not a creative idea," the silver-haired girl from the royal capital, who had become a fourth-level rune master as an apprentice, finally let go, she spoke softly, and then got up and took a very heavy book from her bedside, "It's logic and calculation. ”

Gawain put his hand on the book, but still asked, "Can I read it?" ”

"Of course, you're a lord."

Gawain opened the large, seemingly old book, and found that it was actually a handwritten notebook, the yellowed and curly pages were full of runes, numbers, calculations, and legends, and some of the handwriting had even been blurred by wear, and he flipped through it at random, and found that the font in the entire notebook was still different: there were at least four different handwriting on the pages, and they appeared in order from front to back: it was clear that this notebook had changed at least four owners, And each owner has left their own record on it.

The book seemed to confirm Gawain's vague suspicions, and he flipped the pages almost with excitement and excitement, so much so that Jenny, who was sitting across from him, began to worry about whether this precious notebook would be damaged by this rough flip through, and in this rapid flipping, Gawain's eyes were suddenly attracted by a piece of attached paper sandwiched in the second half of the note.

The piece of paper was pasted between the pages of the notebook, as if it were an additional annotation or summary, and the words on it made Gawain breathe as if he were choking:

The energy level ratio of all secondary runes to the energy level of the higher rune is always one to three, and if the secondary runes are connected continuously, they are counted as a complete higher rune;

The maximum number of connections between any rune and runes of the same level and different genera of the same level shall not exceed eight, and the maximum number of connections with runes of the same level and the same genus shall not exceed four;

Any rune forms a "knot" with the beginning character to the end character, and the connection fields that can be filled in each "knot" rune must be an even number, and every two connection fields are counted as a "pair", and if the number of "pairs" in the field is X, then the energy level generated by each "knot" rune is (X+1) and the square is taken;

In a mana interference area, two structurally identical and adjacent runic knots are set to form a "interference knot", and the total interference value generated in the area increases dramatically with the number of interference knots. If the interference value of a single interference junction is constant t=1.35 and the number of interference junctions is n, the actual total interference value m=t*n³. (Note: Avoiding adjacent rune knots with identical structures can greatly reduce the generation of interfering knots).

The theoretical interference value that can be withstood when the runes are connected on the positive guide material is set to M, the number of rune knots is set to N, the number of rune attributes is set to Z, and the interference value generated by the interference junction is constant t, then the theoretical interference value that can be withstood by the rune group within the scope of the guide material is M=(N+Z*N)*t, and the interference value of the negative guide material is divided by the constant E=1.66......

In any case, it should be ensured that the actual interference value m is less than or equal to the theoretical interference value M......

In a compound magic circle, the formula for calculating the "self-interference" generated inside the rune knot is ......

In a compound magic array, the best arrangement of each rune should be followed......

More on the trail later.

A large number of formulas, laws, and logics are almost all written on this appendice, and many can be seen on the pages behind the appendice, and Gawain can almost immediately judge that this is a summary and derivation of practical value.

It's just that they still don't seem to be the final product, and they still have some limitations of the era: many of the summaries are purely empirical products, and there is a lack of clear formulas, and many of the formulas are too messy, and have not been simplified or merged into more general formulas, and all of these things have not been organized according to a system, but are piled up here loosely and independently, completely disorganized.

But they're already shocking things.

"Did you sum it up?" Gawain almost screamed as if he were glaring.

"No, no......," Jenny replied with some alarm, "not exactly, only part of this notebook was written by me, and the rest was ...... The legacy of those who came before. ”

When she said the words "the legacy of her predecessors", she had a distinctly gloomy and sad look on her face.

"Hmm...... That's right, there are at least four kinds of handwriting on it," Gawain glanced down at the notebook, then flipped through it and suddenly found that the fonts at the beginning of it were vaguely familiar, and after carefully identifying them, he turned to look at Hetty, "Do you have that notebook with you?" Wild mage that book. ”

Gawain's notes were a treasure in Gawain's eyes, but the most precious thing was the knowledge contained in them, not the notebook itself, so he copied a copy of the notes, kept the copy himself, and gave the original as a gift to Hetty, who was keen on magical research.

Hetty nodded: "Yes, I've been studying the discussion of the general rune group in it for the past two days......"

As she spoke, she pulled the old notebook out of her bosom, and Gawain unfolded it on the table, comparing it with the notebook from Jenny's hand—sure enough, the handwriting of the first quarter of the latter was exactly the same as that of the wild mage!

This thick and old notebook turned out to be one of the relics of the wild mage? And his relic is still circulating in the mage circle, and has been studied and continued by at least three latecomers?

"...... are you" Jenny also saw the notebook that Hetty took out, and she subconsciously spoke, "Do you know its owner?" ”

"I've seen it before," Gawain said casually, pointing to Jenny's notebook with rune calculation formulas, "Since you have this in your hand, it proves that you've seen him too?" ”

"It's a shame that it had already changed hands three times when I got this notebook," Jenny shook her head, "You've seen him?" Where is he now? Is it also in this camp? ”

The expression on the runemaster's face was a hint of reverence and excitement, but Gawain had to let her down: "He's dead, and the notebook I have in hand is his only relic. Now, of course, you'll have to add the one you have. ”

Jenny opened her mouth, but finally turned into a sigh: "Is that so......"

"You say this notebook has changed hands three times, but what about its previous owners?" Gawain didn't give Jenny much time to immerse himself in emotion, he followed up and asked, "Those who advanced the research on the notes, are they still in the royal capital or the secret puja?" Can you reach them? ”

"They...... Dead too," Jenny's tone suddenly became very low, "its second master died on an expedition, and its third master, who came before me, was Mr. Raven Keys, with whom I studied runes, and who died in a mission arranged by his mentor - the constant E=1.66 is his inheritance. ”
