"It would be good to have some achievements in order to start a 3D magic circle.
If Jin offered, he would have gotten the OK with a single word, but that was not what he wanted.
"Let's make something simple, something practical, something that can be applied..." he said.
"That might be a good idea.
Jin said, and Katya agreed with him.
We need something with a general use and something that will show that this is something worth studying for the future.
"The easy one would be magic lighting," he said.
Eira is also thinking about what we should do.
"Yes. At least it would be easy and practical.
Jin agrees to try to make a magic light.
"The main thing would be to collect in the surrounding space, turn it into , and activate the magic of <>," he says.
Jin described the flow of magic control (magi sequence), saying that it should be possible to turn it on and off with a switch.
"Yes, that's good. ...... Jin, don't tell me. I wanted to tell you.
Eira laughed and complained to Jin.
"Sorry, sorry. I'm sorry. ...... So, as far as the appearance goes, I'd like something I can put under my pillow or on my desk to light up my hand."
"Yes, something like Jin said would be fine."
"Okay. I'll make the stand itself, while Eira and Katya make the magic circle.
Jin divides the work between the two of us.
Reiko, help me.
"Yes, Father!"
Reiko was so excited that her turn had come at last.
(Secretly, get some high quality wood from the old man. (Sneak in a bit of fine wood from the old man, just enough to make a ...... stand.)
(Yes...)
Jin instructs Reiko in a whisper so that Eira and Katya can't hear him and with sound insulation.
Twenty seconds later, <> was sent.
"Oh, teak."
Teak is one of the three most famous woods in the world today. (The other two are mahogany and walnut.)
It is hard and durable and does not rot even in seawater, so it is widely used for ship decks, house doors, furniture, bridges, etc. It has a unique sheen when polished.
Polishing gives it a unique luster.
It is interesting to note that silica (silicon dioxide) sometimes precipitates in the inner conduits (tubes that allow water to pass through), which can impair the sharpness of knives.
Using the teak, Jin made a magic stand, not an electric stand.
"Done."
The design incorporates a bit of Japanese style, giving it an "andon" (paper lantern) appearance.
The base is 20 cm square and 5 cm thick. Two pillars extended from it to support a cylindrical hibukuro (fire cover) covered with paper.
Inside this fire bag, the magic of <> was activated.
Since no heat is generated, there is no need to worry about a fire.
"This one's ready too!"
A relatively inexpensive <> with three layers of magic circle.
The first layer collects , the second layer converts it into , and the third layer activates the magic of .
A switch is installed to activate or deactivate the magic circle of the first layer.
The idea was simple: to turn the magic circle on and off by disconnecting and connecting parts of it.
It took only a minute to install the <3D magic circle> created by Eira and Kaechea into the created by Jin.
Jin flips the switch, and the lights come on with a time lag of about one second.
This time lag is a drawback of the magic circle method, but Jin and the other three think that it is possible to use it as a lighting fixture.
"It's bright enough!
"Yes, this would be at a practical level. It could be brighter if it were written on a larger board, or if the magic circle that collects the <> were written using two layers.
Eira mentioned something she had noticed after trying to make it.
"That's something we'll have to work on in the future."
"Yes, that's right. I guess that's it for the lighting fixtures for now.
"What about something more promising?"
It's only 3:30 in the afternoon, plenty of time to build something.
"Well, I think I'd like to make a <>.
Generally, it would be a combination of an <> and a <>.
"That would cause a large fluctuation in output, wouldn't it? Isn't it difficult to use the magic circle method?"
Eira countered.
"Yes, that's true, but it's our contribution to technology to work around that, isn't it?"
Jin further retorts.
"That's a good argument, but is there any chance?"
"Yes."
"Well? Let's hear it.
"Of course."
Jin shared his thoughts.
"What I'm going to make is probably not a finished product. It will be a prototype.
He prefaced his speech with the following words.
"First of all, the reason why the magic circle method is not suitable for applications with fluctuating output is because it is slow to react.
"Right."
To put it in a simple way, the magic circle method amplifies the magic power by making it pass around in a circle over and over again.
It is a little different from the actual situation, but it is like accelerating charged particles with a cyclotron. The more times the particles go around, the more they are accelerated.
Therefore, the time taken for the is the time loss.
The time is about 0.4 to 3 seconds.
This is too slow compared to the current Golem's average reaction time of 0.1 seconds and the fastest one of 0.04 seconds.
"That's why I'm adding <>."
"<>?"
A term mainly used in electric circuits to refer to a device that temporarily stores electricity.
Comparing it to a stream of water, one of the functions of a magic circle is a water source, and a capacitor is a small tank. There is a faucet attached to it, which feeds the golem engine or other power source .......
When the amount of water in the water source is not very large, the tank can be filled with water once, so that the amount of water can be supplied without any problem even if the faucet is opened and closed frequently to change the amount of water to be taken out.
"I see.
"I see," said Mr. Jin, "That's how you think, Mr. Jin.
Both Eira and Katya seemed to have realized how they were going to do it after hearing Jin's analogy.
"The equivalent of a tank is literally a . I think a smaller one would be fine."
"Indeed. In other words, you usually store a little bit of mana in the mana tank to meet unexpected demand.
"Well, yes."
"That's a good idea. Then, the most expensive Magi Device would be the Mana Tank.
And the mana tanks are relatively inexpensive to produce.
"Hmmm, that would be worth studying at the !"
"Right? And since it's so versatile, I'm sure other laboratories could use it as well."
"It's worth studying!"
Eira, Jin, Katya, and the others thus began work on the prototype of a new .
