The reason why Rebecca said "cannot be used" is simple.

Ordinary people do not have the ability to charge the magic array, nor can they control the opening and stopping of the magic array.

The professional magical array of the mages and the simple symbols carved on the stone by the people are completely different. The latter is like using a wooden stick as a walking stick from the roadside, while the former uses a variety of technical means to create a wheelchair. The gap is equivalent to the original material and the industrial product - the symbol on the stone will continue to work without the participation of outsiders. Although it is weak, it does not require any skill, but the magic array... it is a complicated operation. .

You only need to lift your legs when you run on both legs, but if you want to reach 70 mph, you have to buy a car and add a bit of oil. Then you can take a driver's license. The same is true for the law. It needs energy infusion and needs to have magical skills. The professionals are responsible for opening and closing - even if it is a simple law.

Herti and Rebecca can go to the blacksmith shop without regard to their identity to describe a simple combustion-supporting array on each stove, but they can't stay here every night to charge the array every other ore. And is also responsible for controlling the energy flow of all the arrays.

"If you want to engrave the squad on the stove, then its volume is bound to be limited, even if it is the aunt of Hert, probably only the secondary array of second order and below can be engraved," Rebecca explained very seriously. And try to make your expression look professional. "And such a small-scale squad is impossible to do self-energy - the arsenal of free magic can at least be as big as a tent, so The array on the furnace must be charged, and even the simplest array only needs to be switched, and most people can't control it..."

Through the memory of Gao Wen Cecil, Gao Wen knows that the magic array of this world has a very complicated classification and operation principle, and if they do not consider the expertise that is huge, they can also be roughly classified:

From the scale classification, it can be divided into small, medium, large and super large. The smallest array can be engraved on the armor sword. At present, the two largest magic arrays in the world are located in the city of the Thousand Towers in the northern Violet Kingdom and the mainland. The "Star Temple" built by the Southern Elves, the two magical arrays are based on the city, and are outlined by urban roads, which can be described by scale terror.

From the functional complexity classification, it can be divided into two types: single function type and composite type.

From the charging method, it can be divided into two types: self-charging and external energy-injection. The self-charging magic array has a complicated "snap" structure, which can absorb the free magic of the outside world and charge me. However, since the free magic in nature is thin except for the magic focus, the structure of the self-charged array will be quite large, so all self-charged arrays are large, and all small arrays All can only be supplemented by external energy injection.

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

A self-charging structure tends to occupy 80% of the entire magical array, and it can provide more energy than a tributary of any magic focus, but a large area of ​​the drawing area can be inserted. There are several complex rune arrays, so from the perspective of efficiency, the wizards prefer to charge themselves to the array instead of choosing a slow and bulky self-charging structure.

That's why all the big magical facilities in the world are located near the magic focus: it's because of the convenience of charging.

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

Then he asked two questions:

“Do you have to put the charging part on the stove?”

"Do you have to put all the functions in a magical array?"

Rebecca groaned, and some of them were blind, but they blinked: "Do you?"

Gao Wen vaguely felt that the key to the problem was caught: the people in this world seem to focus only on turning magic into the most primitive and rude power, or simply focusing on the individual's use of power, and never considering how to make this "extraordinary power" Promote in a broader, lower-based way.

"Draw a large self-charging array, let it capture the magic of the air, and then leave the 'output' on this large array, and output the magic to the small array on the furnace, so the charging problem will be solved. And the switch problem... can make the connection between the furnace and the self-charging array become controllable. After the cutting, the small array will naturally stop, and the large self-charged array itself will be overcharged. Nature, don't worry about being bombed..."

Rebecca quickly understood Gao Wen’s philosophy in his own way: “Spray the magic array into pieces and use it together? Is it still?”

"This is a little bit of an idea," Gao Wen nodded. "I think we can talk to Herti - she should be more professional."

Rebecca agrees deeply - although Aunt Herti's caster can only reach the level of human stroke, but with regard to theoretical knowledge, those middle-level wizards may not be able to compare her!

So Gao Wen led the people and left the place, leaving the old blacksmith Hanmer and a group of apprentices and handymen.

"Master, let's go... is it open?" An apprentice cautiously asked, when the Duke and the Viscount stood in front of him, he couldn't breathe. At this time, he finally dared to speak.

The old blacksmith glanced at the apprentice: "Crap! Of course, open the stove! Don't think about being lazy - you can't eat meat at night and you have to see the results of this furnace!"

On the other side, Gao Wen had sent amber to call Herti to her tent, but after he had finished his thoughts, the elegant lady shook her head.

"The idea of ​​using one array to recharge another is very good, but it is too difficult to operate... The output of the magic is very precise. Once the 'interface' goes wrong, both arrays will Scrap. And the efficiency of the self-charged array is also a big problem. Even if you draw a big array like the blacksmith's compound, the magic it produces may not drive a few magic furnaces..."

Gao Wen looked at Hetty, of course he knew that the other side would raise these difficulties, but he actually had a solution.

So he smiled slightly, and as he thought more and more deeply on this issue, he felt that he finally found the route he should really take, so he pushed the pile of drawings on the table aside and put An extra large sheet of paper with symbols and lines spread out on the table.

The thing on this piece of paper was that he had finished drawing a few days ago, but until today, he realized what it could be.

"Look at this." Gao Wen said.

Herti was surprised to see the large array of runes on the table. The first reaction was that her ancestors could learn more and more to this degree: "The ancestor... you still know how to draw the squad?!"

"I only know a little, and this law is not created by me," Gao Wen deliberately sold a piece. "You look at it first, what do you think?"

Herti bowed her head and carefully studied every symbol above and the connection between the symbols. The brow slowly wrinkled: "All are the most basic runes... The arrangement and combination are also the most basic, like the highest. Does the energy level not exceed the second level?"

Gao Wen nodded: "Because the people who left this array can only control the rune array of energy intensity level two at most."

Herti looked up at him in surprise, and then looked down at the face and couldn't help but admire a bit of admiration: "It turned out that all the basic runes were used to complete the design... with the most basic characters Wen made such a large-scale legal array, this... really incredible creation... This seems to be a structure that can extract free energy from the natural environment? But what are the redundant structures that are redundant..."

Gao Wen pointed to the repetitive structure of the Central District of the squad: "Zoom in."

"Zoom in?" Herti's eyes widened, and then suddenly realized, "Yes! This can magnify... and the structure here can further purify the free energy... so that these basic runes can be higher. The efficiency to extract free energy, this is really... really..."

Herti "really" for a long time did not think of the proper vocabulary to describe the feeling that this squad brought to her, but Gao Wen knew what she wanted to say: "It’s really hard, right? It’s like a lame man holding Crutches traveled all over the world, just as unarmed people carved a verse on a stone with a wooden stick. This is an effort beyond the limit, drawing a basic second-order rune that can make those big magicians stunned. miracle."

"Those big magicians are probably not stunned, they won't even look at it," Herti smiled and shook her head. "Because this circle is very creative, it is all pieced together with second-order runes." Even if it is more efficient, the energy it draws cannot be compared with the personal magic wells that the great magicians have..."

"But it is a prototype, a basic model that can be continuously improved. It only has second-order runes, but if you change the second-order runes to third-order based on this idea? If you combine their complexity Upgrade to the third order? How many times will the efficiency of the existing self-charged array be?” Gao Wen said, pointing to a few special nodes in the array, “except for efficiency, Look at these more critical parts."

"This... seems to be a magic channel?" Herty frowned. "I saw them just now, but I didn't see the corresponding energy-consuming unit. Is it because the array is not complete?"

"No, it is from the beginning that this array does not contain energy-consuming units. Its only function is to supply magic to the outside world - to supply magic to a weak human. For this reason, it is different from the internal interface of the general array. The 'compatibility' of these channels is so high that they can be docked with them as long as they are energy-consuming units," Gao Wen said slowly. "Now, can this array provide energy to the blacksmith?"

"If all the symbols can be played smoothly... No, it will work smoothly. It has almost reached the limit of the calculation!" Herti's face gradually became excited, and she finally got from the traditional mage's mindset. Jumping out, realizing the greatness of this thing, "high efficiency self-charging, and can also output energy with a fairly wide 'frequency', it can completely power the blacksmith, and even... can give more Something for energy!"

Then she couldn't wait to ask: "The ancestor, what is the name of this genius?"

Gao Wen took out a dilapidated note from his body: "I don't need to name it - its creator has given it a name."

The notes are opened and a short note is written on one of the pages:

"Annie, I finally finished the ‘Magic Net’ today, I hope it will bless your health.”

(Second, I would like to recommend a ticket to enjoy the reward)
