Jin and the others moved to the workshop to teach Marikka engineering magic.
"Yes? What is it?
"Well, it's about Hannah.
Hannah?
Yes. Hannah is very smart, isn't she?
Yes.
I think it's a shame.
"Yes, yes."
"So, can't we give her access to engineering magic?"
"...... that's what you mean."
"Brother Jin, Hannah is very smart, so I think that would be a good idea."
Erza agreed.
Jin had also thought about it a little when he had seen the in Mitsuho.
"If we put it in my workshop over there, Hannah can use it too. ......Good!"
Jin decides to try his hand at making a <> with Marikka as his assistant. Erza observes this time.
First, the machine dedicated to <>.
"Here, we write the Magi Formula, and it processes the information that is input from here. Then, using the optimized data, activate <>."
"Ugh, please try again. ......"
"Sorry, sorry, that was a little fast."
I was explaining to Erza in such a tone of voice that Maricka couldn't follow me.
"This Magi Formula connects the operator and this Magi Machine. This is called an interface.
Is it an interface?
Yes. In other words, it is responsible for transmitting the will of the human being to the magical machine. Without it, a person who cannot use magic will never be able to use this magical machine.
"Ah, yes!
Marikka understood as I slowly explained the structure, composition, and purpose of the machine.
Jin spent the rest of the day building the machine with explanations.
The image of the machine is a stand-alone 3D processing machine.
"First things first, I guess."
The size of the machine is about that of a small study desk. The top board is 90 centimeters wide and 50 centimeters deep.
On one side is a magic screen and an input device, which resembles an all-in-one desktop computer.
The display is a magic screen and the keyboard part resembles a game controller.
The rest of the top panel was engraved with a magic circle.
"Amazing, Master Jin! With this, even those who can't use magic can do all kinds of processing by <!"
"That's my brother Jin!"
"No, there were similar machines in modern Japan when I was there. What's really amazing is that Marikka thought it would be a good idea to make something like this.
"Huh!"
Marikka blushed at Jin's praise.
"I'm an engineer, for better or worse. If I were an inventor, I'd be third-rate or worse."
"I don't think so. ......"
Erza is not happy with Jin's self-evaluation.
"Well, well, that's not important."
Jin changes the subject.
"Let's take it to the village of Kaina tomorrow."
"Yes.
"Yes, I'm looking forward to it."
* * * *
On November 5, Jin, Erza, Reiko, Zion, and Maricka moved to the village of Kaina.
They set up the completed <<<< transforming (forming)>>special machine in a corner of Jin's workshop.
"That's right. You can tell it what you want to make here: ......."
Marikka explains.
Her tone seems to change a little when she is talking to Hannah.
"At ......, put the ingredients on this magic circle and press this <> button, and the engineering magic in the device will work and you'll be done."
"Amazing! Did you make it, Marikka?"
Marikka looks a little embarrassed at these words,
"No, it was Master Jin who made it. I just helped a little.
She answered honestly.
"Really? Thank you very much, Onii-chan!"
Jin explained.
"This Magi-machine can only do forming. As for the size of the object it can make, you see the magic circle here? The size of the object you can make is limited to something that doesn't extend beyond the magic circle.
"Yes, I understand!"
The body is 50 cm wide, 40 cm high, and 40 cm deep, but the magic circle is in charge of the processing. The body is 50 centimeters wide, 40 centimeters high and 40 centimeters deep, but the magic circle is in charge of the processing.
"Copper, bronze, iron, and clay are the materials. Wood cannot be processed. Crystals can be processed, but not ordinary stones. ...... Well, there's no danger of making a mistake, just that nothing will happen."
"Yeah."
"Let's give it a try first."
Jin brought a block of silver from the workshop and placed it on the magic circle.
"The excess will be splashed properly, so it's better to put more on top. If there is not enough, the shape will be as instructed but the size will be smaller.
Jin makes Hannah sit down as he explains.
"Let's make a plate for the easy part. Use this button: ......."
A button similar to the arrow button on a game controller and a joystick-like lever.
Using these buttons and levers, Jin drew a three-sided view. Hanna already has knowledge in this area.
"You can specify the size here: ......"
Hannah listens to Jin's explanation with a serious face.
"And when you are satisfied with it, press the button."
The magic circle glows faintly and the silver nugget is quickly transformed into a plate. The remainder remains as small silver nuggets.
"Wow, that's great!
Hannah is very excited.
"And finally, there is a function to return it. When you press this button, ......"
The magic circle glows faintly again, and the plate returns to a silver nugget.
"Wow!"
"You can do it over and over again. You can practice. This is a prototype at ......, so if you notice anything while using it, please let me know. We'll improve it."
"Yeah, okay!"
"When I get used to it, I'll make a magi-machine that can do other kinds of processing.
"Thank you, girl! Thank you, Marikka!
Seeing Hannah's smiling face, both Jin and Marikka were glad that they had made it.
"Marikka-chan, let's try it together!"
"Oh, you sure?"
"Of course!"
Hanna immediately tries out a few things with Marikka.
"Yes, of course! Marikka, let me know if you notice anything. I want to make it as good as possible.
"Yes, Jin-sama!"
< took its first step.
This was the beginning of the generalization of magical engineering.
