Herty's explanation sounded unclear at first, but Gawain guessed the effect of the device in front of him from these words, and he froze for a moment, and in his excitement there were endless questions in his mind—but before they filled his mind, Kamel's voice regained his attention.

After all, this magister from ancient times was calmer than Hetty, and when he saw that Gawain had not expressed an opinion, he took the initiative to ask, "Lord, do you have any questions about this device?" ”

"How are you ...... A breakthrough? Gawain looked at Hetty, "I remember that you and Rebecca studied for a long time, but couldn't find a way to stabilize the magic divergence effect of the Holm Crystal - your research was stuck for a long time because it couldn't measure any parameters stably. ”

"It was an accident, Ancestor, and we should be grateful to Master Carmel for coming, without him, I'm afraid we would have been stuck in this bottleneck for longer," Hetty calmed down and said with an irrepressible smile, "Rebecca and I caught Master Carmel's attention when we were testing how to activate the magic field more efficiently, and his special life form reacts very well to mana...... Susceptible. ”

"It's really ...... Sensitive," Carmel hummed, "I can sense precise changes in the magic field, and I can directly 'see' the reaction of this crystal when it is stimulated by magic, especially after learning about its magical properties, I have a huge interest in it......"

Gawain quickly figured out how Kamel had accidentally participated in Hetty's experiments, and how they had worked together to break through the difficulty of precise control of the crystal, all of which made Gawain sigh: bringing Kamel out of the fortress of disobedience was definitely one of the wisest decisions he had ever made in his life.

"I've used the rune design ideas from the Gondor era - of course, these circles have undergone a lot of changes, thanks to the help of Jenny and Rebecca, without them, it would have been unimaginable to rearrange the runes in the traditional way," Carmel sighed heartily, pointing to the runes and notches on the metal structure of the magic channel, "and thanks to my mutated body, I was able to interfere with the flow of magic in ways I never thought possible." The device in front of you is a mature sample, and after my initial tests, it can be operated for a long time under stable and controllable conditions. ”

Gawain didn't talk nonsense: "Demonstrate." ”

"Very happily." Kamel said, then he floated next to the device and poured his magic into its base, which was not currently connected to the web of the Lord's House, and Carmel used it as an energy source himself.

After the magic was injected, Gawain saw a scene that he would never forget in his life-

The magic guide device emitted a slight buzz, and the crystal structure of its main body was quickly lit up, and a large number of blue light lines appeared on the surface of the crystal, and began to change as if breathing, and the metal base and top cover of the device also began to tremble slightly at the same time, with a soft "click" sound, the fixed buckles everywhere in the device automatically popped open, and then the top cover above it and the Holm crystal as the main body broke away from the base under the action of magic and began to float slowly!

The entire device, which had been connected together, eventually became three separate parts, with the base firmly fixed to the ground, and the main crystal and the upper top lid floating in the air, emitting an intoxicating pale blue glow as the magic surged.

A steady, continuous mana field centered on the device and rapidly spread into the surrounding space.

Before Gawain could speak, Hetty had already picked up another device from the table: it was a simple metal tray with a thumb-sized Hom crystal fixed in the center of the tray, and a depleted storage crystal fixed to the card slot next to the tray.

As the Holm crystal on the tray glowed synchronously with the magic guide device in the center of the study, Gawain saw that the surface of the magic storage crystal also shone with a pale blue halo, and the entire crystal was brightening at a speed visible to the naked eye.

It's a receiver, and it's charging the crystal!

Gawain suppressed the excitement and excitement in his heart, and quickly asked, "What is its effective range?" ”

"This experimental device can cover an entire block of mana fields - in fact, it will cover a much larger area, but at a distance of more than three hundred meters, the strength of the mana field will quickly decay, and it will hardly provide effective mana output outside of this range."

"What about the load-bearing aspect? For example, if there are a large number of magic machines running at the same time in this area, will this crystal be able to hold on? If it can't bear it, what safety measures does it have to prevent accidents? ”

"I thought about it. This experimental crystal can theoretically support hundreds of the largest magic energy engines at the same time, and this value will definitely be higher after the later improvement of the process, but if the mana consumption rate in the range really exceeds the limit of the crystal, then this floating limiter will play a role in the flow - its floating effect is maintained by a levitation circle engraved on the blackstone matrix, once there is a too strong mana surge in the range, the fragile blackstone will immediately break, The limiter will fall onto the crystal, and when the two come into contact, it will form a rune trigger-like loop, changing the connection of these runes on the surface of the crystal, forcing its output power to decrease - if this still does not relieve the pressure on the crystal, then the second limiter on the base will melt itself later, causing the crystal to fall back into the pedestal, and completely cutting off the external output. However, in this case, the base is completely scrapped and must be replaced as a whole before it can be used again...... But it's better than losing the main crystal body or having a waste energy explosion. ”

Gawain suddenly looked at the small metal structure floating above the crystal: "So this is the first-level limiter...... You used Blackstone in the limiter? Is this the idea of the 'insurance medium' in the magic net? ”

"Yes, I'm referring to the 'insurance' device you designed in the magic web," Kamel admits with some embarrassment, and then sighs a little, "This is really a train of thought and learning - inferior materials have their uses, and as long as they are used properly, their fragility is a value in itself......"

"As far as I know, the security devices that people set up in magical facilities during the Gondor era usually put a saturated charged crystal embedded in the circuit breaker and use it to blow up the runaway magic circle unit...... the idea of 'fuse' is the same, and the cost can vary greatly."

Kamel sighed: "After all, magic was not worth much in that era, and there were many charging crystals. ”

Gawain sighed as well, but he looked more at the crystal device that was still running, and because Carmel had not stopped supplying energy, the device was still floating steadily in mid-air, continuously releasing energy to the outside world.

A problem that the magic network has been facing for a long time has finally been solved.

That's the transmission of energy, or the problem of "wiring".

Mana is a very special kind of energy, and although it is becoming the foundation of Cecil's industrialization, it has a very different nature from the "electricity" that serves as the industrial foundation of the earth: it cannot be transmitted by "wires".

Magic can only be transmitted through runes, through rune arrays connected together to conduct, the traditional so-called "magic guide material" is actually just shaping it into a certain unit in the magic array, so that it can conduct magic power, and there is no way to shape the magic guide material into filaments, you can transmit magic power to a distance - before the appearance of Hetty and Kamel's device, the only way to transmit magic power to a distance is to honestly spread the magic net unit all the way.

What does this mean? It means that if you want to channel magic to every corner of a place, you have to spread a magic net in every corner! At the very least, it is necessary to ensure that there is at least "one column" of magic net units in the place where the magic power is transmitted.

Even if the cost of each "hive unit" is low, it will require a staggering amount of resources, and the rune substrates will be lined up, which is much more expensive than drawing the same metal into filaments to make wires.

What's more, after more and more high-rise buildings appear in the territory, the supply of magic power will also encounter the problem of height difference, which is even more unrealistic to simply lay a magic net to transmit magic - not only have to use magic arrays to pave the ground, but also have to use magic arrays to paste the walls, which even if Gawain turns his head and digs up the grave of Charles I, it is not consumable!

Gawain did tell Rebecca that he wanted to spread the magic net all over the world, but he didn't mean to......

Of course, due to the dispersion of magic power, even if there is no direct physical contact, the magic net unit can provide energy to items within a certain range, but this distance is actually pitiful: a single magic net unit can only emit magic power a few centimeters, and even if it is a factory-level magic net, the distance between the "rubbing nets" around it is only a few meters...... Completely impractical.

But with the device in front of him, the bottleneck of magic transmission has finally been broken.

Cheap, convenient, and the technology that can transmit magic without having to spread the magic net all the way through is right in front of Gawain's eyes.

After a long time, he withdrew his gaze and looked at Hetty and Kamel standing beside him, "What's the name of this device?" ”

"I haven't named it yet," Hetty shook her head slightly, "this test device was also just made by Kamel - I didn't know that until I got back to the lab, I brought it to you." ”

Speaking of this, she lowered her head a little embarrassedly: "I know it's not too rigorous...... This kind of thing should be tested more and reported to you when we have more detailed data, but I can't help but want to tell you the good news and want to ...... Show it off. ”

"It's okay, I understand your excitement," Gawain smiled and waved his hand, Hertie looked like a mature and steady person, but in front of Gawain, she would accidentally reveal such a childish side from time to time, which was also a personal characteristic, "Since it doesn't have a name yet, it's called ...... The magic energy obelisk, the obelisk that transmits magical energy, is simple and easy to understand, how about it? ”

"Ah, that's a good name," Kamel admired the name, and the brightness of his whole person increased a little, and then he gradually stopped injecting energy into the magic obelisk, allowing the various components of the device to land and put together again, "I will complete the rest of the test items on it as soon as I get back, and hand over the materials to the Mechanical Research Institute for Mr. Egg to arrange production." ”

"Very well," Gawain nodded approvingly, pleased to see that Kamel had adapted to the rules of the territory in such a short period of time, and that his relationship with Nicholas Egg seemed to be quite good, and then he took a deep breath and exhaled slowly, "But while basking in joy, let's not forget to think about some questions." ”

Hetty was a little puzzled: "Thinking about some questions? ”

"Ask a little more why," Gawain said unhurriedly, looking at the obelisk of magical energy that had stopped working, "Have you ever wondered why magic can spread remotely and steadily without rune contact?" Why can't the one that escapes from the magic web? Why is it that magic is ubiquitous in the natural environment, but only the magic extracted through the magic net and released through the magic obelisk can be harnessed? Extending from these questions, what is the nature of magic? How has the magic in nature changed since it entered the magic web? These are all questions. ”

Looking at the looks of Kamel and Hetty, Gawain paused, and continued: "And in addition to these questions that require long-term thinking, we can also think about it - what else can this magic that can be transmitted remotely be used to transmit energy in addition to it? ”
