The reason Rebecca said "it won't work" is simple.
Ordinary people do not have the ability to charge the magic circle, nor can they control the start and stop of the magic circle.
The professional magic circles of mages are completely different from the simple symbols engraved on stones by ordinary people. The latter is like picking up a stick from the side of the road as a crutch, while the former uses various technical means to create a wheelchair. The gap is equivalent to raw materials and industrial products - the symbols carved on the stone will continue to produce effects without the participation of outsiders. Although weak, it does not require any skills, but the magic circle... It is a complex thing that works.
To run on two legs, you only need to lift your legs to walk, but if you want to reach a speed of 70 miles per hour, you must at least buy a car, fill up the gas and get a driver's license. Professionals are responsible for opening and closing - even the simplest magic circle is the same.
Hetty and Rebecca could go to the blacksmith's shop to carve a simple combustion-supporting magic circle on every furnace regardless of their status, but they couldn't stay here all day and recharge the magic circle every other ore furnace. , and is also responsible for controlling the energy flow of all magic circles.
"If you want to engrave a magic circle on the stove, its size is doomed to be limited. Even with Aunt Hetty's ability, you can probably only carve auxiliary magic circles of the second level and below," Rebecca explained seriously. He said, and tried to make his expression look more professional, "It is impossible for such a small-scale magic circle to be self-charging—a magic circle that can absorb free magic power by itself must be at least as big as a whole tent, so the melting furnace Someone must recharge the magic circle on the top. In addition, even the simplest magic circle only needs to be switched on and off, and ordinary people cannot control it... "
Through Gawain Cecil's memory, Gawain knew that the magic circles in this world have very complicated classifications and operating principles, and if they don't consider the overwhelming professional knowledge, they can also be roughly classified:
In terms of scale, it can be divided into small, medium, large and super large. The smallest magic circle can be engraved on armor and swords, and the two largest magic circles in the world are located in the city of a thousand towers and the mainland of the Violet Kingdom in the north. The "Temple of Stars" built by the southern elves, the two magic circles are based on the city and outlined by the city's roads, which can be described as terrifying in scale.
According to the classification of functional complexity, it can be divided into two types: single function type and composite type.
According to the charging method, it can be divided into self-charging and external charging. The self-charging magic circle has a complex "absorbing" structure, which can absorb the free magic power from the outside to self-charging. However, since the free magic power in nature is very thin except for the magic focus, the absorption structure of the self-charging circle will be quite large, so all self-charging circles occupy a huge area, and all small magic circles They can only supplement energy by means of external energy injection.
And in this world, the self-charging magic circle is actually something that is rarely used—because the efficiency is too low.
A self-charging structure often occupies 80% of the area of the entire magic circle, but the energy it can provide cannot compare with the weight of any one branch of the magic focus, but it can be stuffed into such a large area of drawing area. There are several rune arrays with complex functions, so from the perspective of efficiency, mages would rather choose to charge the magic circle by themselves instead of choosing a slow and huge self-charging structure.
This is why all the large magic facilities in this world are located near the magic focus: it is because of the convenience of charging.
Gao Wen stroked his chin and looked at the blacksmith's furnace in front of him.
Then he asked two questions:
"Do you have to draw the charging part on the stove?"
"Do you have to put all the functions in a magic circle?"
Rebecca was stunned for a moment, and blinked for some unknown reason: "Otherwise?"
Gao Wen vaguely felt that he had grasped the crux of the problem: people in this world seemed to only focus on turning magic power into the most primitive and crude power, or simply concerned about the individual's use of power, and never considered how to make this "supernatural power" Spread out in a broader, lower-based way.
"Draw a large self-charging circle, let it absorb the free magic power in the air, and then leave an 'output terminal' on this large circle, and output magic power to the small magic circle on the furnace, so the charging problem will be solved Yes, but the switch problem... can make the connection between the furnace and the self-charging circle controllable. After cutting off, the small magic circle will naturally stop, and the large self-charging circle itself has the nature of overcharging and dissipation , and don’t worry about being blown up…”
Rebecca quickly understood Gawain's idea in her own way: "Disassemble the magic circle into pieces and use them together? Is it still possible?"
"This is more or less an idea," Gawain nodded. "I think we can discuss it with Heidi—she should be more professional."
Rebecca deeply agrees with this - although Aunt Hetty's spellcasting accuracy can only reach the level of human body strokes, but in terms of theoretical knowledge, those middle-level mages may not necessarily be able to match her!
So Gao Wen led the people to leave this place in a hurry, leaving the old blacksmith Hammer and a group of apprentices and handymen looking at each other.
"Master, shall we... still turn on the furnace?" An apprentice asked cautiously. He didn't dare to breathe when the Duke and the Viscount stood in front of him just now, and finally dared to speak at this time.
The old blacksmith glared at the apprentice: "Nonsense! Of course open the furnace! Don't try to be lazy—whether you can eat meat at night depends on the results of this furnace!"
On the other side, Gawain had already sent Amber to call Hetty to his tent, but after he finished his thoughts, the elegant lady shook her head.
"The idea of using one magic circle to charge another magic circle is very good, but it is too difficult to operate... The output of magic power is a very precise thing. Once there is a problem with the 'interface', both magic circles will be scrapped .And the efficiency of the self-charging magic circle is also a big problem. Even if a magic circle as big as the blacksmith's compound is drawn, the magic power it produces may not be able to drive several magic furnaces... "
Gawain looked at Heidi, of course he knew that the other party would raise these difficulties, but he actually already had a solution.
So he smiled slightly. As he thought more and more deeply on this issue, he felt that he had finally found the real route he should take, so he pushed aside the pile of drawings on the table, and put An extraordinarily large drawing full of symbols and lines was spread out on the table.
The thing on this paper was drawn by him a few days ago, but until today, he didn't realize what use this thing could be useful for.
"Look at this." Gao Wen said.
Hetty looked at the large rune array on the table in surprise, and her first reaction was that her ancestor could be so knowledgeable: "Ancestor... you know how to draw a magic circle?!"
"I only know a little bit, and I didn't create this magic circle," Gawain said deliberately, "Look at it first, what do you think?"
Hetty lowered her head, carefully studied each symbol on it and the rules of connection between symbols, and slowly frowned: "All are the most basic runes... The arrangement and combination are also the most basic, as if the highest The energy level does not exceed the second level?"
Gao Wen nodded: "Because the person who left behind this magic circle can only control the rune array with energy intensity level two at most."
Hetty looked up at him in surprise, and when she looked down again, the expression on her face couldn't help showing a hint of admiration: "It turns out that the design is really all done with basic runes... use the most basic runes To create such a large-scale magic circle, this... is really an incredible creation... This seems to be a structure that can absorb free energy from the natural environment? But what are these redundant and complicated structures... "
Gao Wen pointed to the repeating structures in the ring area of the magic circle: "Zoom in."
"Zoom in?" Hetty's eyes widened, and then suddenly realized, "That's right! This can be zoomed in... and the structure here can further purify free energy... In this way, these basic runes can be used with higher efficiency. Come to absorb free energy, this is really... really... "
Hetty spent "really" for a long time and couldn't think of the right words to describe the feeling this magic circle gave her, but Gawain knew what she wanted to say: "It's really hard work, right? It's like a lame person supporting himself The crutch has traveled all over the world, as if an unarmed person carved a poem on a stone with a wooden stick. This is an effort beyond the limit, using the most basic second-order runes to draw a world that can make those great magicians dumbfounded. Miracle."
"Those great magicians probably won't be dumbfounded, they won't even look at it straight in the face," Hetty smiled wryly and shook his head, "Because although this magic circle is very creative, it is made of second-order runes after all. After all, no matter how efficient it is, the energy it absorbs cannot compare to the personal magic wells owned by great magicians... "
"But it is a prototype, a basic model that can be continuously improved. It only has second-order runes, but what if you replace the second-order runes with third-order runes on the basis of this idea? If you increase their combined complexity What about raising it to the third level? How many times will its efficiency be that of the existing self-charging magic circle?" Gao Wen pointed to several special nodes in the magic circle while talking, "In addition to efficiency, You look at these more critical parts."
"This... seems to be a magic channel?" Hetty frowned. "I saw them just now, but I didn't see the corresponding energy consumption unit. Is it because the magic circle is not complete?"
"No, from the very beginning, this magic circle does not contain energy-consuming units. Its only function is to supply magic power to the outside world—to supply magic power to a weak human being. And because of this, it is different from the internal interface of ordinary magic circles. These The 'compatibility' of the channel is so high that as long as it is an energy-consuming unit, it can be connected to it," Gao Wen said slowly, "Now, can this magic circle provide energy for the blacksmith?"
"If all the symbols can function smoothly... No, they will definitely function smoothly, it has almost reached the limit of calculation!" The look on Hetty's face gradually became agitated, and she finally jumped out of the traditional thinking of a mage Come out and realize the greatness of this thing, "Highly efficient self-charging, and it can also output energy at a fairly wide 'frequency', it can completely power the blacksmith shop, and even... more things Energy Supply!"
Immediately afterwards, she couldn't wait to ask: "Ancestor, what is the name of this genius magic circle?"
Gao Wen took out an old notebook from his body: "I don't need to name it—its creator has already given it a name."
The note was opened, and on one of the pages was written a short line of notes:
"Annie, I finally completed the 'Magic Net' today, may it bless your health."
