Interference magic circles. Admittedly, Gwen Cecil was half a naturalist, and Knight had a lot in common with other mages in the field of using magic. But when it came to those subtle and specialized fields, Gwen's knowledge was still a little lacking. He had to ask Heti before he figured out what was so special about the magic circles engraved in the antique crystals.
In a nutshell, they belonged to the category of 'area of effect'.
This type of magic circle could operate on energy storage devices within a specific range, and did not have to be engraved on the surface or inside the energy storage device. In other words, as long as the key nodes of the magic circle were connected to the energy storage device, the effect could be activated. In this respect, the interference magic circle was very similar to the common large-scale magic circles. The large-scale magic circle was to build a magic circle, and then put the energy source such as the energy storage crystal at the key nodes of the magic circle as the energy source. Of course, this kind of structure was not engraved in the crystal, but in fact, there was a fundamental difference between the interference magic circle and the common large-scale magic circle.
The interference magic circle was usually very small, its range of effect was very small, and its function was very simple. Its rune structure was actually not complete, and the energy storage part and the rune part had to be combined together to be a complete 'execution mechanism'. Therefore, the interference magic circle was usually used as a 'starting mechanism' to simply control the opening and closing of some mana sources, or …
To blow up the mana source.
Gwen understood why the Gondor mages engraved interference magic circles in the military crystals. Logically speaking, since they had stuffed the runes inside the crystal, there was no need to spend the effort to set it up as an interference magic circle. But in reality, the problem that the soldiers faced on the battlefield was much more complicated. Not all military crystals could remain intact throughout the entire battle. Many times, it was normal for such crystals to crack and be damaged prematurely due to the intensity of the battle. At that time, the magic circle at the core of the crystal might still function because it was well-protected, but the whole crystal had actually disintegrated.
Under such circumstances, the rune specialists in the Gondor military field thought of one thing: at least, they had to ensure that the self-destruct function of the crystals could still be used in the end.
Therefore, the self-detonation part of these crystals used an interference type magic array. This kind of magic array ensured that even if the crystal shattered, a handful of fragments would explode — as long as there was a little bit of energy left in these fragments.
"I just don't know what the effect will be when a large number of these crystals are gathered together and detonated at the same time." Gwen touched his chin and began to think. "Or use something to glue them together? And we still don't know how they are formed. Only a small portion of the large number of samples sent by Rebecca contained this kind of crystal … "
Heidi looked at Gawain's face. She could feel that Gawain's excitement was at an all-time high, which made her a little confused. Although she was happy that these weird crystals could be put to good use, she could not imagine how valuable these 'magic crystals', which had no other uses except for explosion, could be. "Ancestor … You look happy?" she asked.
"How can I not be happy?" Gwen turned his head and looked at Heti. "Don't you think that once these things are put to good use, they will be of great use?"
"Hmm … If it is processed properly, it may be used as an explosive magic tool. It is useful for mages of average strength like me and Rebecca. It can also be used as an auxiliary weapon for soldiers." Heidi had pushed her imagination to the limit. "But other than that, I can't think of anything else."
Gwen looked at Heti's confused expression. He opened his mouth but found that it was difficult to make her understand the picture that was emerging in his mind.
No one who lived in the Middle Ages would have been able to imagine the scene before they saw the explosion and mass production with their own eyes.
So he simply did not explain. Instead, he waved the parchment in his hand. "I'll leave these samples to you. To be honest, there are not many of them. Try to determine their nature before you use them up. Also, try to see if the 'detonation magic array' in the Gondor crystal works on them. I'm going to look for Rebecca and find out how that girl came up with these things. "
Heti took the parchment from Gwen's hand. Then, as if she remembered something, she deliberately said, "Ancestor, Rebecca is a very hardworking child, but she has hardly been praised since she was a child, so …"
"Don't worry, I'll praise her." Gwen smiled and pointed at the parchment in Heti's hand. "I've even decided to call these crystals' Rebecca's crystal '— if that girl can recreate these crystals."
After that, Gwen reminded Heti to pay attention to safety when testing the detonation magic array. Then, he left the magic lab.
Until Gwen left, Heti was too embarrassed to say what she really thought. In fact, what she meant was that Gwen should be careful when praising Rebecca. That girl had never been praised since she was a child. Once someone praised her, she might jump to the sky …
But forget it. Since the ancestor was so happy, it was better not to spoil his mood.
Anyway, Rebecca was resilient and optimistic. If she really jumped to the sky, she would just beat her up …
After leaving the magic lab, Gwen went straight to the place where Rebecca tried to burn the cement. But he did not find her. Only a few workers were cleaning up the burnt residue in the furnace area. After asking around, he found out that Rebecca had gone to the 'steel factory'.
The foundation of the magic network had been completed, and the first furnace had entered the final stage of installation. Rebecca went over early in the morning to supervise the work.
Gwen checked the residue in the furnace and confirmed that there were no crystals mixed in it. Then, he set off for the 'steel factory' on the east side of the camp (although the frame had just been set up).
As soon as he arrived at the place that was called the 'blacksmith' not long ago, Gwen realized that he had been right to leave this matter to Rebecca.
The courtyard that had been excavated to bury the magic array had now been flattened. There were no traces of the magic array on the solid ground. The only thing that could prove that there was indeed a magic array buried under the ground was the silver-white pillars that were neatly arranged every ten meters on the surface of the courtyard.
Those pillars were the original version of the magic sensor plated with a mithril layer.
In addition to these 'sensors' that were more than a meter high, Gwen also saw many neatly arranged stone slabs in the courtyard. These stone slabs were distributed between the sensor pillars with equal spacing, but they only covered half of the courtyard.
Runes could be seen shining on the surface of the stone slabs.
Gwen vaguely guessed what these stone slabs were for.
The whole project was done beautifully and reasonably. Not only was the magic circle "sealed" in a very appropriate manner, but the neatly arranged columns and slabs were even more satisfying. They were so pleasing to the eye and so precise. Even though Gawain knew that they were handmade and not industrial products, he still felt greatly satisfied as a person with obsessive-compulsive disorder.
Tidiness, tidiness was the way of the king! Rebecca completely understood all the requirements that Gwen had given her, and she had even thought of the future needs of this place to expand production. The places that had not been paved with stone slabs had also been reserved for the future.
Many people were busy in the courtyard, moving tools and cleaning up the residue, but Rebecca's figure was still easy to find. Gwen saw the large black furnace in the corner of the courtyard at a glance, and the iron fireball doll that was waving its hands and commanding the furnace.
"Be careful, be careful … This structure has to fit perfectly with the stone slabs! Don't be perfunctory! Accuracy, accuracy, do you understand … If it doesn't fit properly, there will be no meat to eat. Do you understand this time? Hey, don't put the iron rod next to it. Let's install the child runes first … Where's the drainage channel? Move the drainage channel here … Let me take a look at the blueprint! "
Looking at Rebecca who was immersed in her work with excitement, Gwen did not have the heart to disturb her. He stopped a few serfs who wanted to salute him when they saw his face and raised his head to look at the newly installed furnace with appreciation.
It was a … very beautiful furnace. Compared to the old furnaces which were only one meter tall, this one was more than four meters tall. It was completely black (this was because black stone powder was mixed into the materials used to build the furnace to further enhance its magic affinity). It abandoned the traditional "big belly furnace" structure and used a rectangular furnace as the main structure. On the upper end of the rectangular furnace, there were three chimneys arranged in parallel, and on the right side of the lower end, there was a protruding rectangular surface. The surface was inscribed with not very complicated runic circles. Part of the runic circles extended to the front of the furnace body, where there was a metal plate that seemed to be movable. Below the metal plate, there was a connecting rod that was connected to something like a pedal, which seemed to be some kind of control mechanism.

Since the control mechanism was located at the front, the openings for fuel replenishment, ore pouring, slag extraction, and liquid metal discharge were all at the back and left side of the furnace body.
It did not look like any of the furnaces on Earth that Gawain knew of in his previous life. It was also completely different from the traditional furnaces of this world. It did not even match the blueprint that Gawain had given to Hanmer.
Obviously, the old blacksmith had used his brain and improved the blueprint.
In Gwen's view, this improvement was excellent, whether it was the result of the improvement or the "improvement" itself, it was excellent.
It was only then that Rebecca noticed that the people around her had quieted down. Everyone was looking at her in awe. She looked around in a daze, and only then did she see her ancestor circling around the furnace.
The little girl was shocked. "Ah! Ancestor! Why are you here? "
"I have something to tell you, but now I see your progress." Gwen waved his hand with a satisfied smile on his face. "To be honest … it's better than I thought."
"Really? Really?" Rebecca was overjoyed. "You really think so?"
"If you can't do these things well, I will definitely not let you be in charge of it." Gwen could not help but smile. "Be confident in yourself. As I said, you are the pride of the Cecil family."
When Rebecca heard this, her face almost went up to the sky.
