After discussing the model of the hive magic net and promising the "reward", Gawain did not let Rebecca and Jenny leave, but took out some drawings he had made these days, as well as some inductive summaries and calculus materials for "rune logic" based on his own understanding.

Rebecca's attention was drawn to Gawain's drawings, and Jenny saw the calculations of Gawain's calculus at a glance, and the latter's eyes widened in surprise: "You did all this?" ”

"When I'm not idle, study the information you gave me, and try to put together the rune sorting myself," Gawain smiled and nodded, "I still have some foundation in magic theory. ”

"This ...... It's not a matter of basics," Jenny looked at Gawain's results incredulously, "and there are still ...... these calculations Writing habits, have you ever been exposed to this before? ”

"The Gondor Empire had a lot of achievements in mathematics and physics—of course, rune logic didn't develop." Gawain casually perfunctory, and the actual situation is only known to him: he has indeed not been exposed to rune logic before, but the mathematical ideas accumulated in his previous life are still there, even if the formula is not universal, the idea of logic and calculation will not fail, so far the rune logic formulas sorted out by Jenny are still in a fairly simple stage, and it is not difficult for Gawain to understand those calculations extended by empirical formulas.

Seeing that Jenny still had a tendency to continue to ask questions, Gawain quickly turned the topic to the next stage: "Let's take a look at these things first." ”

"This is the 'second-generation magic engine' you mentioned last time, what is it called a rotor engine or something......" Rebecca flipped through the drawings in front of her, "I haven't seen this before...... This circle model seems to be of the fire type? ”

"It's a scorching ray circle, a second-level magic that can release a focused beam of heat from the focus of the circle," Gawain explained, "Anyway, it's just low-level magic, one level lower than a big fireball...... You haven't seen it? ”

"I haven't seen it," Rebecca shook her head, "Aunt Hertie taught me the scorching ray spell model, and she thought it was the same as the fireball spell, maybe I could learn it—it turned out that my brain hurt when I learned this spell, and then I had a psychological shadow, and then I slept through several classes when I learned how to convert this spell model into a magic circle......"

Looking at this N+1 great-granddaughter who calmly confessed the black history, Gawain was simply dumbfounded.

The so-called scorching ray is not a profound spell, although in Gawain's opinion, this biu is a magic that can be hit by light and light at the level of light and shadow effects, but in fact it is only a second-level magic, which is one level higher than the first-level small fireball, and Rebecca is a "third-level magician" who can rely on her strong mental power to hold back the big fireball, it stands to reason that the scorching ray is not a problem for her at all, but there is no way, in the transcendent realm of this world, the so-called talent for spell casting is destined by God, For a mage who relies on his personal qualities to cast spells, if he is born with a spell casting defect, no matter how hard he tries, he will not be able to do it.

If you try too hard, you can even get a headache.

But here is an extra thing to say, although Rebecca can only have one "fireball technique", but in fact she can forcibly claim that she can do two magic - the small one is a small fireball, and the big one is a big fireball, these two spells are one level and one level three, and their spell models are almost identical, but the latter needs to be infused with more magic power and controlled with higher mental power. Rebecca was born with only one spell model, and this spell model was a fireball, so she said she could do two spells......

Gawain always felt that if this girl continued to deviate from this talent tree, sooner or later she would be able to bring out nuclear fusion......

"Ancestor, why are you showing me this?" At this time, Rebecca had already read a few drawings, looked up and asked curiously, "Are you going to build this rotor-type magic engine again?" ”

"When making complex magic energy machinery or high-level magic props, what bothers us the most is 'interference'," Gawain said what he has been thinking about recently, "In the operation of the magic array, the energy flow between the runes and the runes will interfere, and the two adjacent magic arrays together will also interfere, and the high-level magic props will be more disturbed because of the complexity of the magic circle and the large number of rune nodes-this is also the main factor for the low yield and high price of high-level magic props. Traditional mages have not been able to solve this problem completely, and this is the most important reason why transcendent items are difficult to proliferate. ”

Jenny looked at the calculation formulas written by Gawain, and suddenly had some enlightenment, revealing a thoughtful look.

And Gawain continued: "We have discussed the rotor engine last time, and its only problem is interference, there are too many repulsion arrays, and the arrangement is symmetrical, so interference cannot be avoided, and we have to give up for the time being, and this thermal ray array ......"

"There shouldn't be any interference problems with the thermal ray array, right?" Rebecca said uncertainly, "I don't, but I know that this kind of circle has long been a mature technology, and many mages like to set this kind of trap in their mage towers - it is very powerful, and it doesn't blow up things around it like fireballs, so it can deal with those intruders with great precision......"

Gawain waved his hand: "Yes, the thermal ray circle has been used, but that's because traditional mages have 'solved' the interference problem by carving it on an expensive guide base, but I'm going to draw it on a cheap red copper substrate, and the runes are made of cheaper quartz sand and red blood gum - this is another interference problem." ”

Jenny vaguely guessed what Gawain meant: "You want to reduce its cost - but drawing the circle on inferior magic guide materials means that the energy level of each rune will be suppressed by the material, and the effective power will be reduced, and in order to ensure that the circle can work, it is necessary to increase the effective power by increasing the number of runes, and in the concept of many traditional mages, the more runes, the higher the chance of interference." ”

"That's right," Gawain said unhurriedly, "Drawing or engraving the circle on low-level base materials, or making runes from inferior materials, will reduce the 'effective power' of the runes, so it is necessary to increase the number of runes to ensure that the circle can exert its original effect, and the more runes, the higher the chance of causing the circle to collapse due to interference." Traditional mages have solved this problem by carving their circles into expensive high-tier materials, so that they can accomplish their goals with the most streamlined structure of the circle - they are used to avoiding distractions because they are not short of money. ”

Rebecca: "But Ancestor, you've been trying to make the transcendent ...... What do you mean by that word? ”

Gawain glanced at her approvingly: "Cheap mass production." ”

He then continued: "All the problems are due to the unique 'interference' nature of magic, and the interference of magic circles is actually an obstacle to cheap mass production, which has increased the cost of many low-level magic items, and also caused many of the machines I designed to be unable to operate, but now they are ...... We have ideas to solve the interference. ”

"The idea is to calculate through rune logic!" Jenny has been fascinated by what she has been listening to, she has been studying the rules of runes for many years, but she only uses it to design the magic circle and complete the tasks assigned by the mentor, this is the first time she realizes the true value of these mathematical tools at a higher level, "Traditional mages believe that it is the increase in runes in the magic circle that causes the interference and collapse of the magic array, but in fact, we can calculate from the formula that the increase in runes will not lead to interference, on the contrary, the more runes give the magic circle a higher ability to resist interference - what really causes interference, It is the 'interference knot' generated by the runes when they are arranged in a specific way, and it is only because the interference generated by the interference knot increases exponentially, far exceeding the anti-interference ability brought about by increasing the rune knot, so people have always believed that as long as there are more runes in the magic circle, it will be unstable......"

Gawain laughed and smiled very happily: "That's right, with rune logic, we don't have to study in the dark like those traditional mages, and we don't have to rely on luck and unreliable experience to design magic circles like them, such as the rotor type magic energy engine I designed before, we can reduce the interference knot by fine-tuning the rune arrangement of each repulsion circle, and even redesigning the way of repulsion circles, or we can also use the same method, Draw or engrave circles that would otherwise require expensive magic materials to make on cheap copper plates, and make them cheap enough for everyone to use! ”

"Anyone can use ......," Jenny was visibly frightened by the statement, "is that possible?" ”

Gawain asked rhetorically, "Why is it impossible?" Now even the brickburners and miners in the territory are using magic energy engines, so isn't the magic energy engine essentially a magic item? ”

Jenny was speechless.

"So you're going to let us do the math of these things?" Rebecca looked at the drawings that Gawain took out, and suddenly a eager expression appeared on her face, "Ah, I see that you also marked the price range of base materials and rune materials next to each magic array...... Do you want to get the circle running on such a cheap basis? Looks challenging! ”

"Have faith?" Gawain asked with a smile.

Rebecca puffed up: "Special!" ”

Jenny smiled a little shyly and reservedly: "I will work hard, and I will not let you down." ”

The two girls left with a large pile of new drawings and materials, while Gawain relaxed, leaning his upper body back in his chair and letting his thoughts drift.

He thought that he had finally found the right path that would allow ordinary people to enter the realm of the occult.

He also grasped the way to maximize the efficiency of the "magic" of this world.

The "what you think is what you do" nature of magic is the greatest help to turn his whimsical ideas into reality quickly!

In a world without magic, it may take years or even decades or generations for an idea to be transformed into reality, and the difficult process of tool production and improvement takes up most of the time, but in the world where magic exists, this process is greatly shortened, almost all of the time cost is actually done between the brain and the pen and paper, as long as the mage calculates quickly and accurately enough, then as long as he completes the spell model, his spell will become a "thing" that can work in reality, Even if their magic is still their own for the time being, the "practical significance" that that magic can produce has already been realized.

All Gawain had to do was transform these spells into magic engines, thermal ray guns, crystallization bombs, and hive nets one by one......
