Intervention-type magic circles must admit that although Gawain Cecil is half a naturalist, and knights have a lot in common with other magic professions in the basic field of using magic, but it really involves those subtle and In the professional field, Gao Wen's knowledge is still a little insufficient. He asked Hetty about it, and then he found out what is special about the magic circle engraved in those antique crystals.
In short, they are "scope effect".
This type of magic circle can operate the energy storage device within a specific range, and it does not have to be engraved on the surface or inside of the energy storage device. In other words, as long as the key nodes on the magic circle are connected to the energy storage device, the effect can be launch. From this point of view, the interference-type magic circle is very similar to the common large-scale formation. The large-scale formation is to build a magic circle, and then put magic power sources such as energy storage crystals on the key nodes of the magic circle to act as energy sources. Of course, this kind of structure does not belong to engraving the magic circle in the crystal, but in fact there is still an essential difference between the interference type magic circle and the common large-scale formation.
Interference-type magic circles are usually extremely small, with a very small range of action and a single function, and its own rune structure is actually not complete. The energy storage part and the rune part must be combined together to be considered a complete "executive mechanism." ", so this kind of interference-type magic circle is usually regarded as a "starting mechanism", which is used to simply control the opening and closing of some magic power sources, or...
Used to blow up the mana source.
Gao Wen understood why the Gondor magisters carved an interference-type magic circle into these military crystals. It stands to reason that since they have already stuffed these runes into the crystal, there is no need to bother to set it up. It is an intervention type, but the actual problems that soldiers have to face on the battlefield are much more complicated. Not all military crystals can remain intact throughout the battle. The crystal-like normal state, at this time, the part of the magic circle at the core of the crystal may still be able to operate due to proper protection, but the entire crystal has actually disintegrated.
In this case, the rune experts in the Gondor military field thought of one thing: at least make sure that the self-destruct function of these crystals can still be used at the end.
Therefore, the self-explosion part of these crystals uses an interference-type magic circle. This kind of magic circle ensures that even if the crystal is broken, a piece of debris can be exploded as long as there is still a little energy left in these pieces.
"I just don't know what will happen when a large number of these crystals are gathered together and detonated at the same time," Gao Wen touched his chin, and began to conceive in his mind, "Or use something to bond them into shape? And it's not clear what they are now." How it was formed, only a small part of the large number of samples sent by Rebecca was mixed with this crystal... "
Hetty looked at Gawain's face, and she could feel that the other party's interest was unprecedentedly high, which made her a little confused: Although she was also very happy that these weird crystals would come in handy, she couldn't imagine that except How valuable is a "magic power crystal" that has no other purpose other than explosion: "Ancestor... you look happy?"
"How can you be unhappy?" Gawain turned his head and glanced at Heidi, "Don't you think these things will be of great use once they come in handy?"
"Well... if it is processed properly, it may be used as an explosive magic item. It is really useful for ordinary mages like Rebecca and me, and it can also be distributed to soldiers as auxiliary weapons," Hetty said. Imagination stretched to the limit, "but I can't think of anything else to do with it."
Gawain looked at Hetty's confused expression and opened his mouth, but he found it difficult for the other party to understand the picture that was emerging in his mind.
Anyone who lived in the Middle Ages would never have imagined those scenes before witnessing the dynamite mining and industrial mass production.
So he simply did not explain, but raised the sheepskin bag in his hand: "I leave these samples to you. To be honest, there are not many of them. You try to determine their various properties before consuming them all. By the way, try to see if the 'explosive circle' in the Gondor crystal works on them. I'm going to find Rebecca and find out how the girl tossed these things out."
Hetizhen took the sheepskin bag from Gao Wen's hand with great importance, and then, as if remembering something, she specifically mentioned: "Ancestor, Rebecca is a very hardworking child, but she has hardly been praised since she was a child. ,so… "
"Don't worry, I will praise her well," Gawain smiled, pointing to the sheepskin bag in Hetty's hand, "I've even decided to call these crystals 'Rebecca Crystals' If these crystals reappear."
After saying this, Gawain reminded Heidi to pay attention to safety and do a good job of protection when testing the detonation circle, and then left the magic laboratory.
And until Gawain left, Hetty didn't have the nerve to say what she really thought in her heart. In fact, what she meant was to let Gawain take it easy when praising Rebecca. The child had never been praised since childhood. Might as well jump into the sky...
But forget it, since the ancestor is so happy, I better not spoil his interest.
Anyway, Rebecca is resistant to beatings and optimistic, if she really jumps into the sky, it will be a big deal to give her a good meal...
After Gawain left the magic laboratory, he went straight to the place where Rebecca was trying to make cement, but he was in vain. There were only a few workers in the kiln area to clean up the burnt residue. After asking, he found out that Rebecca has gone to the "steel factory".
The basic part of the magic net has been completed, and the first furnace has entered the final installation stage. Rebecca went to supervise the construction early in the morning.
Gao Wen checked the slag that had been cleared out of the kiln, and after confirming that there were no crystals mixed in, he set off for the "steel factory" on the east side of the camp (although a shelf has just been erected now).
As soon as he came to this place which was called "Blacksmith Shop" not long ago, Gao Wen realized that he was right to leave this matter to Rebecca.
The yard where a large number of ravines were dug to bury the magic circle has now been re-leveled properly. There is no trace of any magic circle on the compacted ground, and the only thing that can prove that the magic circle is indeed buried underneath is the surface of the yard. There is a neatly arranged silver-white column every ten meters or so.
Those pillars are the original version of the magic sensor plated with mithril coating.
In addition to these "sensors" protruding from the ground with a height of more than one meter, Gao Wen also saw a lot of neatly arranged stone slabs in the yard. Only half of the yard was paved.
Shiny runes can be seen on the surface of the slate.
Gao Wen vaguely guessed what these stone slabs were for.
The whole project is completed beautifully and reasonably. Not only is the magic circle extremely properly "encapsulated", what is even more satisfying is the neatly arranged columns and stone slabs. They are so pleasing to the eye, so strict and precise, even if they know They are products of handcraft rather than industry, and Gao Wen still feels that he has been greatly satisfied as an obsessive-compulsive disorder.
Neat, neat is king! Rebecca really fully understood all the requirements that Gao Wen gave her, and she also thought of the need to expand production capacity in this place in advance! Those places that have not yet laid stone slabs have also reserved vacancies, obviously for the future!
There were many people busy in the yard, moving tools to clean up the leftovers, but Rebecca was still easy to find, because Gawain saw the large black furnace in the corner of the yard at a glance, and she was dancing and doing things beside the furnace. The head of the command is Iron Fireball.
"Be careful, be careful... This structure must be able to fit the stone slab perfectly! Don't be perfunctory! Accurate, accurate, do you understand... If you don't stick it properly, you will have no meat this time, you understand now!! Hey, the one next to it I don’t need to put the iron rod, I’ll put the sub-rune on later... Where’s the drainage tank? Move the drainage tank here... Let me take a look at the blueprint!"
Looking at Rebecca who was so excited and immersed in her work, Gawain couldn't bear to disturb her. He stopped a few serfs who were terrified and wanted to salute when they saw his face, and looked up with appreciation. Looking at the newly installed furnace.
This is a... very beautiful furnace, compared with those old furnaces that are only more than one meter high, it is more than four meters high, and the whole body is pitch black (this is because the materials used to build the furnace are mixed with black stone powder to further enhance the magic affinity nature), it abandons the traditional "big belly furnace" structure, and instead adopts a rectangular parallelepiped furnace as the main structure. On the upper end of the rectangular parallelepiped furnace, you can see three chimneys arranged in parallel, while on the right side of the lower end you can see I saw a protruding rectangular plane, engraved with an uncomplicated rune circle on that plane, a part of the circle extended to the front of the furnace body, where there was a metal plate that seemed to be movable. There is also something like a pedal connected by a connecting rod, which seems to be some kind of control mechanism.
Since the control mechanism is located on the front, the openings for refueling, ore pouring, slag removal, and molten metal export are all located at the rear and left side of the furnace body.
This is neither like any kind of melting pot on Earth known to Gawain in his previous life, nor is it completely different from the traditional melting pots in this world. It doesn't even fully match the blueprint that Gawain handed to Hammer in the first place.
Obviously, the old blacksmith used his brains to improve the drawing.
In Gao Wen's view, this kind of improvement is excellent, whether it is the result of the improvement or the "improvement" itself, it is excellent.
And it wasn't until this time that Rebecca noticed that the people around had become much quieter, and everyone looked in awe. She looked around in a daze, only then did she see the people who were circling around the stove. old ancestors.
The little girl was startled: "Ah! Master Zu! Why are you here?"
"I have something to look for you, but now I saw your progress by the way," Gao Wen waved his hand, with a satisfied smile on his face, "To be honest...it's better than I imagined."
"Really?!" Rebecca suddenly showed a look of overjoyed, "You really think so?"
"If you can't do these things well, I will definitely not let you be responsible for it long ago," Gawain couldn't help smiling, "Be confident in yourself, as I said, you are the pride of the Cecil family."
When Rebecca heard this, her face almost went up into the sky...
(Mom, it will be available tomorrow!)
