Jin immediately realized that Erza was talking about a futon made of cotton.
"But if it's a futon, don't you think it's already prepared?"
"Yes, that's right. That's right. But I don't think they have anything better than that futon.
The futon is made of magic cotton wrapped in magic silk, the quality of which has Erza's approval.
"I see. ...... but what if it doesn't fit the bed?"
"Then we'll just make a bed for her."
Elsa is very perceptive today. Or maybe Jin is a little slow.
"Okay, that's good. Thank you, Elsa.
After thanking Elsa, Jin turned to Hannah.
"Hannah, is your tooth okay? Does it hurt?"
It seemed that he was worried about Hannah and couldn't concentrate at the moment.
"Yes, honhyan. Laihyun."
It's no wonder that her pronunciation is a little airy in places. One upper and one lower front tooth were missing.
"Speaking of which, does Elsa have any cavities?"
"Nope. No."
"Jin-sama, I taught Erza to keep her mouth clean since she was little.
Meane added.
"I have been teaching the children in the village since the other day. Fortunately or unfortunately, I don't know if it's because they don't eat much food with sugar, or if it's their constitution, but none of them seem to have cavities.
"I don't hear of many cavities in this village.
Martha laughed as she showed me the inside of her mouth. All thirty-two of her teeth were in perfect condition.
"Hmmm, there could be a reason for that. ......"
Jin is relieved to hear that cavities are not a concern in the village of Kaina.
He then decides to start on his main task of making a futon.
"Can you tell me the size of a typical futon?"
Jin asks Meane.
"Yes, a newlywed couple would use ......."
Meane cut him off and looked pained for a moment. She must have been remembering something from the past.
"It is 2.2 meters long and 2.2 meters wide. The mattress and quilt are the same size.
It's about the size of what we would call a king-size futon on modern Earth.
"Thank you. ...... sorry."
"What are you apologizing for?"
Meane said to Jin with a smile.
* * * * * * * * * * * * * * *
"Now, let's see about the fabric processing.
Jin had come to Horai Island with Erza.
He decided to take this opportunity to teach her how to process cloth. He asks Reiko to show him some samples.
As you can see, there are several kinds of Magi Silk, depending on the weave and the thickness of the thread. First of all, I want you to remember them."
In modern earth, there are plain weave, twill weave, and satin weave. The ratio of warp to weft is, in order, 1:1, 1:2 (warp to weft is skipped every other thread), 1:3 (warp to weft is skipped every other warp).
The types of fabrics were equivalent to chiffon, organdie, tulle, habutae, and so on.
"......"
Elsa is entranced by the variety and feel of the fabrics.
"May I?"
"Uh-huh."
Erza nodded hurriedly as if coming back to herself.
"First of all, cut out the pieces according to size. We're going to use separation, but the crucial difference from taking out the required amount from the ingot is that instead of weight and volume, we're going to imagine size."
"Hmm. I understand."
"Don't expect to get the size you want from the start. If it's going to be off, it's better to make it bigger. You'll waste material, but it's better than if it's too small.
After explaining in detail, Jin decides to give it a try.
"<>"
The medium-thick, plain weave fabric of Magi Silk is processed. The oversized woven fabric had a width of 2.5 meters.
Considering the finished size (taken into account the thickness), it was cut at 2 meters 30 centimeters in length and width. Four pieces of it.
"Normally I would sew them together, but with the engineering magic < ......"
The threads were neatly joined together, and the two envelope-shaped bags were ready in no time at all.
"Put the cotton inside ...... and close them with joints in all four directions ......".
"At this size, the wadding will be too close together, so it would be nice to sew it together in several places."
I explained to him that the outer and inner lining should be careful not to stick to each other, as this would reduce the warmth of the fabric, and I sewed them together, or rather joined them together, using Magi Silk thread.
"How do you like it?"
"...... nice. This is how the futon was made.
Erza was thrilled to see the process of making the futon she was also using.
"Well, try practicing on these strips of fabric."
He gives her a 20 cm wide scrap of cloth and asks her to practice separating and jointing.
"<>. <>. <>,<>".
Repeat the process of attaching and separating many times to get a feel for it.
"...... difficult."
The threads do not stick to each other neatly.
"Haha, it must be difficult at first. You should take that scrap of fabric home and practice.
"Yeah, I'll do my best. I'll do my best.
Next, Jin begins to make the bed.
He recalls his experiences at Reinhardt's house and when he stayed at Princess Rieschen's villa in the Kingdom of Klein, and decides on a design. Basically, it is simple.
Once the design is decided, the next step is the materials. Elsa will be taught woodworking as well, although it may be a little too much for her in one day. We can leave the review to Smith A., we thought.
The wood is in a newly built wood warehouse behind the laboratory. It is kept in a dry environment.
Jin calls them by the names he is familiar with, not by what they are called in this world.
"I think I'll use maple this time."
The wood is dense, resilient, and has a gentle grain.
With the help of Reiko, Jin brought the wood into the workshop and immediately began to work on it.
The main work is separation and jointing, and then shaping.
Elsa watched with a serious look in her eyes.
The process is simple despite its size, and soon a king-size bed is made. Quite large.
The wood is finished off with a coat of varnish prepared by the previous owner. The varnish is expected to have a mothproof and antiseptic effect, and is harmless to the human body. This is also applied evenly using engineering magic.
<>"
The magic to make it soak in evenly. The image of uniformity is also important.
Finally, the surface is polished with "<>" to complete the process.
Elsa watched the whole process with a look of respect.
"Brother Jin, is that the same magic you used to make the spools when we flew kites in the village of Mohut?
Elsa asked as if she remembered. I hadn't seen her make it.
"Yes, I remember that too."
"...... I want to catch up with my brother Jin, even if it's just a little bit."
Seeing Erza's serious eyes, Jin had an idea.
"......Erza, do you really want to become a Magical Craftsman ...... or a Magical Engineer?"
"Yes, I do."
Erza answered Jin's question immediately.
"I want to make various things like my brother Jin and help people. Magic is for making people happy. I don't think it's something to control."
This must have been Erza's conclusion after thinking about it in her own way.
"Okay, I understand."
Jin took out two small magi crystals from the cabinet,
"<>level 3
He copied some of his knowledge into one of them.
"Erza can use transinfo, too, can't she? This Magi Crystal is filled with basic < and other knowledge. Read it.
Jin hands the empty magi crystal and the magi crystal filled with knowledge to Erza. Erza gazed intently at the magi crystal in her hand.
Direct knowledge transfer (trans-info) from one person to another is basically impossible. This is because each person has a different pattern of magical power.
However, it is possible to transfer the knowledge that has been transcribed into a magi crystal to another magi crystal by oneself and read it out.
"...... Jin brother's ...... knowledge."
"Yes. But it's just a beginner's level, right?"
"Okay. I'll try. ...... knowledge transfer (transinfo)"
The Magi Formula floated on the Magi Crystal and was sucked into the other Magi Crystal.
"Yes. You have done it. Erza can read that one directly now.
Erza gave him back the Magi Crystal on which she had transferred her knowledge, and Jin erased it.
Erza looked at the magi crystal in her hand once more and activated "transinfo".
