Greetings, Mister Principal: Save magic

"Are you serious?"

Born couldn't help but look up and down at the young mage. He was handsome and exuded a sense of confidence from the inside out. He didn't look like he was fooling around.

"Most of today's magic props are only engraved with magic when they are made. Although they are simple to use, they are also limited. That is, one prop can only correspond to one kind of magic. Although through some high-level The alchemy method allows one prop to carry multiple magics, but such props are too rare."

Reiner touched his ring. The Hohenheim Gold Cup is such a magic prop. It has many magic spells engraved in it and is worth a lot of money.

"What I want is a prop that can store magic and use it at any time. After use, it can store new magic. In this way, the magic can be set as needed, which is more convenient."

"No, this is impossible... Let's not mention the capacity. When engraving magic, you need to imprint the spell model into the item, unless you can find special materials that can change the properties multiple times... ..No, no, there is a limit to this..."

Hearing Reiner's words, Born fell into deep thinking. There is no doubt that Reiner's idea is quite inspiring. If there is a magic prop that can store different spells many times, , then this is more than just a convenient magic prop.

"This little brother, do you know the concept of magic resistance rate?"

Born asked, picking up a crystal from the shelf.

"Magic resistance rate refers to the resistance rate of objects in a fixed shape to the flow of magic power per unit time. All items that can be made into magic props will have a magic resistance rate that is not too low. It allows the least amount of magic to pass through."

Reiner had some exposure to this concept, but he did not speak out, but listened silently to Bone's explanation.

"When making magic props, magic resistance is a factor that must be considered. Since magic has special effects, it will spontaneously move to places with lower magic resistance. Therefore, inscribing magic actually changes the interior of the object. Its structure allows the magic power trajectory to be formed in places with low magic resistance, which is the basis of the spell model."

After he explained this, Emiya, who was listening quietly on the side, suddenly understood. She didn't understand why magic props could carry magic in the past, but now she finally understood that the spell model was originally engraved on the items in this way. of.

Due to the interference between magic powers, inscribing different spells on the same item also requires special processing, otherwise they will only interfere with each other and cannot be activated.

"So, can you understand that each spell engraved on an item requires a specific spell model. If you want the item to be able to carry different spells, you must change the resistivity composition of the item. Even if you can find it A certain material can erase the spell model many times, but it also takes a long time to engrave and erase the spell model, which is not something that can be done easily!"

After saying this, Bone touched his chin and looked at Reiner.

"Do you have any ideas about the magic storage you mentioned?"

He asked. Although it was difficult to ask the question, it was equally difficult to think of ways to solve the problem. At least Bone himself couldn't find any clue.

"If there is a material whose magic resistivity is not a fixed value, and at the same time, the magic resistivity from all directions is also different, can we achieve short-term storage by changing the magic resistivity of this material? What are the effects of different magics?"

Reiner said that he actually didn't know if there was such a material in the world, but if it could be found, many ideas could be realized.

Let’s not talk about distant magic computers. At least we can make the most basic storage unit, which is the kind of convenient magic prop that Reiner mentioned at the beginning.

"How could this material exist...No, wait, maybe..."

Born originally denied it, but after thinking about it carefully, he seemed to have grasped some clues.

"Between materials with high magic resistivity and materials with low magic resistivity, there may be some materials with magic resistivity in between. Maybe you can try it..."

He fell into thinking and murmured to himself from time to time.

"Boy, your idea is very unique, but I may not be able to find the material you mentioned for the time being."

Born came to the counter, took out a note for recording, and then wrote a series of words on it.

"You can go to the Rainbow Tower to find this guy. He knows more about these magic materials than I do. I have lived in seclusion in this demiplane for more than ten years, and I no longer understand the current development of magic."

He handed the note to Reiner.

Reiner glanced at it and it read, No. 22B, Element Avenue, Rainbow Tower, Shockley Bratton.

He had never heard of this mage's name, but judging from Bone's tone, he seemed to be an expert.

"Thank you."

After accepting the note, Reiner bowed slightly.

"Little guy, since you brought me some fun today, I'll give you something."

Boen said, walked to the room behind the counter, rummaged for a while, then took out a small box and handed it to Reiner.

"Can I really accept it?"

Reiner felt that he just said a few words casually, how could he receive a gift?

But Bone nodded and motioned for Reiner to open it.

Rather than reject the other party's kindness, Reiner opened the box.

In the black wooden box is a pair of rings.

The two rings look exactly the same and are made of silver. They look plain and simple at first glance, but when held in your hands, they are extremely delicate and you can see the delicate patterns in them.

“This pair of rings can guide each other. As long as they are in the same plane, they can indicate the direction of the other ring. When they are close to a certain extent, they will be attracted to each other. Conventional spells cannot prevent it. This process, this is a gadget I made when I was young."

Born told Reiner how to activate it, and saw a subtle fluctuation of magic power spreading, and a red light emitted from the two rings. The light pointed directly in the direction of the other ring, and followed Moving, the direction of the light did not deviate at all, and was still aimed at the other ring.

Holding it in his hand, Reiner also felt a slight attraction. The two rings were like magnets, moving closer to each other.

Is it the kind of thing that makes you hold hands unconsciously as long as you put it on?

Imagining two people walking on the street wearing rings respectively~IndoMTL.com~ and then subconsciously being guided by the attraction of the rings to hold hands, Reiner thought with no trace of origin, when this Boyn was young, he didn't seem to have the same personality. Too serious.

"You and your little lover might be able to use this thing."

Born looked at Emilia and smiled meaningfully.

"No, we are not..."..

Almiya hurriedly explained, but Bone waved his hand.

"It doesn't matter, I understand."

No, you really don’t understand, Reiner said helplessly in his heart. He wanted to explain, but it seemed that Bone had already identified the relationship between the two.

"You should have many places to go."

Born pointed to Reiner's list. There were several shops on it, distributed on different trade floors.

"If you don't hurry up, others will get the good stuff first."
