The glasses are ready, so I leave the workshop and head for the house of the village headman, Giebeck.

Because today is the day of the . It is not good that Elsa, one of the teachers, is not here.

"Jin, what is this study session?

Saki asked, and Jin gave a brief explanation.

"Yes, because there is no school in the village. We teach simple subjects mainly to children. Reading, writing, arithmetic..."

"Oh. That's interesting. So Elsa and Meane are the teachers?

"Yes, that's right."

Saki seemed to be interested in the study group and asked to observe. Since there was no reason not to, and since she wanted to, Jin and Saki were to observe today's workshop.

"What is 23 plus 8? Patty."

"Yes. ......31!"

Correct. Okay, what's 57 plus 6? Uh, Mario.

Uh, 63!

Yes, that's right.

Today is the day of calculation. Everyone answered the two-digit plus one-digit addition without any problems.

Everyone answered the addition of two plus one digits without any problems. "Okay, we will start subtraction today. Page 21 of the textbook at hand.

The textbooks were mass-produced by Golem's high-speed writing. It is made of thinly shaved wood. <
It was reinforced by engineering magic and used.

Jin wanted to make paper, but pulp alone is weak against water, so he is now looking for something like the kind of mallow used in Japanese paper.

This is partly because he does not know how to make paper. I have only made paper from milk cartons. At that time, it was mixed with a little laundry glue.

"You want something water-soluble, but water-resistant once it dries. ......"

I haven't been able to find anything like that. If they could, it would be a big industry for the village of Kaina.

"...... Gin? Jin!"

Jin was lost in thought when Saki's voice called him back to himself.

"Ah, ah, what is it?"

"Oh, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no. The study session is over and everyone has gone home for lunch. Let's go home too.

Then Erza and Meane came in, too, after they had finished putting away the study materials.

"Jin, let's go home.

"Let's go home, Onii-chan."

So Jin, Hannah, Saki, Erza, Mine, and Reiko went back to Martha's house together.

Welcome home. Lunch is ready.

Sarah the golem was waiting for them.

Lunch at the standard Kaina village. Local bread, smoked meat, and vegetable salad.

Eating raw vegetables and fruits for vitamins had started under Jin's guidance, but now it had become a regular practice.

"Hmm, this bread is delicious. It's not pure white, but the fact that it's so white means that there are hardly any crusts in it, right?"

"Yes. Yes, because it's been through a sieve."

"I sifted them myself!"

"I see, Hannah did it."

Lunch proceeded peacefully with such conversation.

After lunch, Saki asked Hannah to show her the sifter.

"You know, you put the kneaded wheat flour into the sifter and shake it.

Hannah demonstrates the process by adding whole wheat flour.

"Oh, I see! That makes sense! Thank you, Hannah!

Saki seemed to have had an epiphany, patted Hannah on the head, thanked her, and turned to Jin and Erza.

"Jin, Erza, I need to talk to you about something."

The three of them then moved to Jin's workshop.

"I had an idea when I saw that sifter," Saki began to explain.

Saki began to explain.

"I understand that you use a sifter to separate large objects from small ones.

Saki looked at Jin's face. Jin nodded his head and affirmed the idea.

"Then, it can be applied to other things besides flour. For example, tea leaves.

"Oh, I see."

Tea leaves inevitably contain a powdery substance called dust. It is difficult to remove it completely, because it is formed when tea leaves are rubbed against each other by shaking them during storage.

This dust is mixed in with the tea and gives it a cloying taste.

"If you sift the tea leaves with a fine net before brewing, the dust will be removed and the tea will taste better.

Jin was impressed. Saki has a broad vision for practical use and application.

"There's more. If we shake the soil and remove the fine dust, we can probably make a well-drained soil."

That's what gardeners are doing on modern Earth.

"The key to sifting is netting. If we put nets on the windows, won't the bugs stop coming in?"

In short, a screen door.

"Saki, that's a good idea. I'm impressed.

"I'm impressed, Saki. Well, now we just need to figure out how to make the key net.

A net is, at best, a net for catching fish. The technique of making nets out of wire is not common. There is no nylon, so there is no idea of a screen door.

"Well, that's true. But first of all, there is an idea. We engineers are the ones who think about how to realize it.

"I'm sure Jin can make it, but it won't be widely used.

Erza also expressed her sharp opinion.

"Yes. Unlike pen nibs and balls, they need to be produced in much larger quantities to be of any use.

"That's what I mean."

It seems that Jin has started to think that it would be a good idea to have a merchant in the village of Kaina.

And this idea will be realized in the near future through the old man.

Now for a quiet conversation.

Now Jin asks Saki a question. This time Jin asks Saki if she has any idea about the adhesive that might be needed to make paper.

"Hmmm, I think the fruit of some kind of plant has that kind of stickiness.

"You mean ogula?"

Just then Meane, who had just brought us some tea, mentioned the name.

Read at https://w w w . m t l r e a d e r.com


"Oh, yes. Oh, yes, the ogla. Is it still in flower by now?"

"No, I think it blooms in mid-summer.

"Meane, tell me what you know about this ogla."

Read at https://w w w . m t l r e a d e r.com


Jin asked Meane what she knew about Ogla, since she seemed to know a little about it. Apparently, it is similar to what we call okra on earth.

Since Tororoaoi and okra are both in the same family, Jin decided that they could be used, and asked the old man through Reiko to secure them.

"Reiko, a word?"

"Yes, father."

"Listen, I need to get that ogura from ......."

Saki smiled at Jin as he whispered instructions.

"Jin must be very fond of Reiko. Aaru is a little different from being adorable. I mean, I'm the one who's been taking care of Aaru.

Elsa quickly joins in.

"Yes. Jin has been taking good care of Reiko for a long time. He sometimes hugs her.

Read at https://w w w . m t l r e a d e r.com


"I'm a little jealous of that, aren't I?"

What?

Huh?"

Read at https://w w w . m t l r e a d e r.com


Elsa looks doubtful, and Saki looks like she doesn't understand their reactions.

Their reactions are similar, but they are completely different.

"If she's cute like Reiko, it's human nature to want to hug her whether she's a doll or an automata, isn't it? I'd like to hold a pretty girl like Reiko in my arms too, wouldn't you?"

Read at https://w w w . m t l r e a d e r.com


"...... Is that what it's like?"

"I heard that Erza even made a mascot doll and gave it to Reinhardt. Aren't dolls cute?"

Erza had no words to reply to Saki's point.

Read at https://w w w . m t l r e a d e r.com


"It's true, I sometimes hold Non, too. Is that the same reason why my brother Jin wants to hug Reiko?

"Well, I don't understand why a gentleman would fall in love with a little girl doll, but..."

The girls' talk takes a funny turn.

"You guys. ......"

The topic of conversation, Jin, looked at the two of them with a pained expression on his face.
