Rebecca says "it doesn't work" for a simple reason.

Ordinary people don't have the ability to charge the magic array, and they can't control the opening and stopping of the magic array.

The magic circle of the mages is completely different from the simple symbols carved on the stone by ordinary people, the latter is like picking up a wooden stick from the side of the road as a crutch, while the former is using various technical means to build a wheelchair, the difference is equivalent to the original material and industrial products - the symbol engraved on the stone does not need the participation of outsiders to continue to produce effect, although weak, but it does not require any skills, but the magic array ...... It's a complicated thing that works.

You only need to lift your legs to run on two legs, but if you want to reach 70 miles per hour, you have to at least buy a car and get a driver's license by the way, and the same goes for magic circles, which require energy infusion and need professionals with magic control skills to open and close - even the most simple magic circles.

Hetty and Rebecca could go to the blacksmith shop and carve a simple combustion circle on each furnace, but they couldn't stay here all day and charge the circle every other furnace of ore, and they were also responsible for controlling the flow of energy in all the circles.

"If you want to engrave a circle on the furnace, then its size is destined to be limited, even with Aunt Hetty's ability, it can probably only carve a second-order and below auxiliary circle," Rebecca explained seriously, and tried to make her expression look professional, "And such a small scale circle is impossible to self-recharge—a circle that can draw free magic on its own must be at least the size of an entire tent, so the circle on the furnace must have someone to charge it." In addition, even the simplest magic circle only needs to be switched on and off, and ordinary people can't control it......"

Through Gawain Cecil's memories, Gawain knew that the magic arrays in this world had very complex classification and operating principles, and they could be roughly classified without taking into account the head-scratching expertise:

From the scale classification, it can be divided into small, medium, large and super large, the smallest magic circle can be engraved on the armor sword, and the two largest magic arrays in the world are located in the city of a thousand towers in the northern violet kingdom and the "temple of stars" built by the elves in the south of the continent, those two magic arrays are based on the city, outlined by urban roads, which can be described as terrifying in scale.

In terms of functional complexity, it can be divided into two categories: single-function type and compound type.

Classified from the charging method, it can be divided into two types: self-charging and external charging, among which the self-charging magic array has a complex "absorption" structure, which can absorb the free magic power from the outside world by itself, but because the free magic in nature is very thin in addition to the focus of the magic power, the absorption structure of the self-charging circle will be quite large, so all the self-charging magic circles occupy a huge area, and all small magic circles can only take the way of external energy injection to replenish energy.

And in this world, the self-charging magic array is actually something that is rarely used - because it is too inefficient.

A self-charging structure often occupies 80% of the entire area of the magic array, and the energy it can provide is not comparable to the weight of any one magic focus and a tributary, and such a large area of drawing area can be stuffed with several complex rune arrays, so in terms of efficiency, mages would rather choose to charge the circle themselves than choose a slow and huge self-charging structure.

That's why all of the world's large magical facilities are located near the focal point of mana: it's because it's easy to recharge.

Gawain touched his chin and looked at the blacksmith's furnace in front of him.

He then asked two questions:

"Do you have to draw the charged part on the stove?"

"Do you have to cram all the functions into one magic circle?"

Rebecca was stunned and blinked a little inexplicably: "Otherwise?" ”

Gawain vaguely felt that he had grasped the crux of the matter: the people of this world seemed to focus only on turning magic into the most primitive and crude power, or simply focusing on the use of power by individuals, without thinking about how to generalize this "supernatural power" in a broader, lower-based way.

"Draw a large self-charging circle, let it absorb the free mana in the air, and then leave an 'output' on this large circle to output mana to the small circle on the furnace, so that the charging problem is solved, and the switch problem is ...... It can make the connection between the furnace and the self-charging circle controllable, and the small circle will naturally stop after being cut off, and the large self-charging circle itself has the nature of overcharging and dissipating, so you don't have to worry about being blown up......"

Rebecca quickly understood Gawain's philosophy in her own way: "Break down the magic circle into pieces and put them together? Can it still be like this? ”

"That's kind of an idea," Gawain nodded, "I think I could discuss it with Hetty—she should be more professional." ”

Rebecca couldn't agree more—while Aunt Hetty's spellcasting accuracy was only as accurate as a human stroke, when it came to theoretical knowledge, those mid-level mages might not be able to match her!

So Gawain led the men out of the place in a hurry, leaving the old blacksmith Hammer and a group of apprentices and handymen looking at each other.

"Master, let's ...... next Is the furnace still open? An apprentice asked cautiously, he didn't dare to breathe when the Duke and Viscount stood in front of him just now, and then he finally dared to speak.

The old blacksmith glared at the apprentice: "Nonsense! Open the furnace, of course! Don't be lazy – whether you can eat meat at night depends on the results of this stove! ”

On the other side, Gawain had sent Amber to call Hetty to his tent, but when he had finished his thoughts, the elegant lady shook her head.

"The idea of using one circle to charge another is great, but it's too difficult to operate...... The output of mana is a very precise thing, and if there is a problem with the 'interface', both circles will be scrapped. Moreover, the efficiency of the self-charging circle is also a big problem, even if you draw a circle the size of the compound of the blacksmith's shop, the magic power it generates may not be able to power a few magic furnaces......"

Gawain looked at Hetty, of course he knew that the other party would raise these difficulties, but he actually already had a solution.

He smiled slightly, and as he thought more and more about the problem, he felt that he had finally found the route he really should take, so he pushed aside the large pile of drawings on the table, and spread out an extraordinarily large drawing full of symbols and lines on the table.

He had drawn the piece of paper a few days earlier, but it wasn't until today that he realized what it could be used for.

"Look at this." Gawain said.

Hetty looked at the large array of runes on the table in surprise, and his first reaction was that his ancestor could be so knowledgeable: "Ancestor...... You even know how to draw a circle?! ”

"I only know a little bit, and I didn't create this circle," Gawain deliberately sold it, "You take a look at it first, what do you think?" ”

Hetty lowered his head, carefully studying each symbol on it and the connection between them, and his brow slowly furrowed: "All of them are the most basic runes...... The arrangement and combination are also the most basic, as if the highest energy level does not exceed the second level? ”

Gao Wen nodded: "Because the person who left this magic circle can only control the rune array of the second level of energy intensity at most." ”

Hetty glanced up at him in surprise, and when he looked down again, the expression on his face couldn't help but bring a hint of admiration: "It's really all done with basic runes...... Using the most basic runes to make such a large-scale magic circle, this ...... What an incredible creation...... This seems to be a structure that can draw free energy from the natural environment? But what is the complicated structure that comes out of this superfluous......

Gao Wen pointed to the repetitive structures in the central ring area of the circle: "Enlarge it. ”

"Zoom in?" Hetty's eyes widened, and then it dawned on her, "That's right! This magnifies the ...... And the structure here can further purify the free energy...... In this way, these base runes can drain free energy with greater efficiency, which is really ...... What a ......."

Hetty "really" hadn't thought of the right words to describe how this circle felt for her, but Gawain knew what she was trying to say, "What a hard effort, right?" It's like a lame man walking the world with a cane, like an unarmed man carving verses into a stone with a stick, it's an effort to go beyond the limits and draw a miracle with the most basic second-order runes that will make even the great magicians jaw-dropping. ”

"Those great mages are probably not dumbfounded, they don't even look at it squarely," Hetty shook his head with a wry smile, "because although this circle is very creative, it is finally cobbled together with second-order runes, and no matter how efficient it is, the energy it draws cannot be compared to the personal mana wells that the great mages have......"

"But it's a prototype, a base model that can be constantly improved, it only has second-order runes, but what if you replace second-order runes with third-order runes on the basis of this idea? What if you also increased the complexity of their combination to the third order? How many times more efficient will it be than the existing self-charging circle? Gawain said as he pointed to a few special nodes in the circle, "And in addition to efficiency, you can also look at these more critical parts. ”

"This ...... Seems like a magic channel? Hetty frowned, "I saw them just now, but I didn't see the corresponding energy-dissipating unit, is it because the circle is incomplete?" ”

"No, from the very beginning, this circle did not contain energy-consuming units, and its only purpose was to supply mana to the outside world - to supply mana to a weakened human. And because of this, it is different from the internal interface of the ordinary magic circle, and the 'compatibility' of these channels is so high that it can be connected to it as long as it is an energy-consuming unit," Gawain said slowly, "Now, can this magic circle provide energy to the blacksmith shop?" ”

"If all the symbols play well...... No, it's sure to work smoothly, it's almost at the limit of the calculus! The look on Hetty's face grew agitated, and she finally jumped out of the mindset of the traditional mage and realized the greatness of this thing, "The high efficiency of self-charging, and the ability to export energy at a fairly wide 'frequency', it can completely supply energy to the blacksmith's shop, and even ...... Power more things! ”

Then she couldn't wait to ask, "Ancestor, what is the name of this genius magic circle?" ”

Gawain pulled out a worn-out notebook from his body: "I don't need to name it - its creator has already named it." ”

The notes flipped open, and on one of the pages was a short line of notes:

"Anne, I have finally completed the 'magic web' today, may it bless your health."
