Magicraft Meister Part 1

"Well, let's pick up where we left off yesterday.

Soleil and Luna had sent her off to clean up the mess, and this morning Erza had also come to the workshop.

The old man reported. And the craftsman (Smith) brings the prototype.

It is a cylindrical vessel made of adamantite, 20cm in diameter and 60cm long.

The container is about 2 mm thick and weighs about 75 kg.

The pressure of a modern earth-made high-pressure cylinder is about 150 atmospheres, which gives you an idea of how strong the container is.

"That was fast. ......"

It seems to be equipped with a pressure reducing valve.

As a matter of fact, it was ready early last night, but when we tried to vent the filled air, the amount of air that came out was not constant, so the old man tried to fix it by trial and error.

The construction of the valve is simple and uses a spring to keep the air pressure constant.

Many of the valves used on the earth today are similar in principle.

"Well done."

<

As Jin wants to complete the spaceship as soon as possible, such labor saving is very welcome.

The old man is aware of this, so he tries to support him except for the things that only he can make.

<

"Yes, what is it?"

<<

"Saki?"

Jin remembered that he had been interested in this at Kali village.

"Jin-brother, would you like to visit there?　If you're busy, I'll go to ......, but..."

Erza, out of concern for Jin, suggests it, but Jin thinks about it for a moment and decides that it's important and that he'll go too.

"Well, ......, you want to go with me?"

"Yes."

Of course, there was no way that Erza could say no, and she nodded her head rather happily.

Jin, Erza, Reiko, and Edgar used the warp gate on the grounds of the Eschenbach house.

The time was adjusted to take into account the time difference, and it was 8:30 a.m. local time.

"Mr. Jin, Ms. Erza, welcome!

Aaru, who had noticed our visit, came out to greet the group.

"Is Saki there?"

Yes, she is in the laboratory.

After confirming Saki's whereabouts, the group went to Saki's laboratory.

"Saki, are you there?

"Yes, I have one.

I don't need two.

"I don't want two." "That's terrible. I don't need two. ......　Is it terrible?

Saki peeked out from the lab with such a lighthearted smile on her face.

"Hey, Jin and Erza. "Good to see you."

"Saki, what are you doing?"

"I wish you could tell me what I'm doing. I'd like to say I'm doing. ...... In a word, I'm researching the tsukiyo-gusa.

This is a luminescent plant used for night-lamps, which he learned about in Kali village at the entrance to the Land of Mitsuho.

Saki was interested in it when she visited there.

She must have collected some kind of tsukiyo-gusa.

"I wanted to know what kind of component of the plant makes it luminescent," she said.

He was trying to extract it.

"There are limited acids, alkalis, and solvents available, so I was planning to go to Horai Island if I couldn't find any here.

The laboratory on Horai Island would have all the reagents they received from 700672, so they would not have to deal with such inconveniences.

"Then, why didn't you do that from the beginning?"

Jin said, to which Saki replied with a wry smile.

"...... but there was a reason why it couldn't be done that way."

She then pointed her gaze toward the back of the laboratory.

There was a man there.

"Hey Jin, Erza, long time no see.

There was Goose.

Guth had become a naturalized citizen, and the Eschenbachs were going to take care of him until he could adjust to the country and find a place to live.

"Hello, Goose."

"Hello."

Goose seems to be assisting Saki in her experiments as her assistant.

"So, what exactly are you doing?

"I'm mixing ground up tsukiyo-gusa with various solvents and seeing if they dissolve."

"Hmm. What exactly?"

"Water, hot water, oil, vinegar, sake, and ."

Saki has read the reference books edited by the "Mere Old Man" in addition to the knowledge she has acquired through <>, so she has the chemistry knowledge of a high school student at this moment.

He is now conducting experiments using this knowledge.

"I see. You are trying to dissolve it in a liquid?

"Yes, it seems to dissolve in water to some extent.

Plant cells are surrounded by a tough tissue called , which is different from that of animal cells. This cell wall is made of cellulose, and Jin has the somewhat vague knowledge that it is made of cellulose (......).

"So, Jin. It is also soluble in hot water, and this is what you get when the water is cooled and filtered.

Saki held up a test tube.

"This water ...... solution is luminescent!"

"Isn't that amazing?"

The luminescent ingredient, which was extracted by grinding the tsukiyo-gusa, does not dissolve in cold water, but dissolves well when the temperature is raised to 70 degrees Celsius or higher.

Once dissolved, it does not seem to precipitate even if the temperature is lowered.

"I'm thinking that if we boil it down, we can make luminescent paint."

"I see."

Jin was pleased that he had gotten a good idea about emergency lighting.

Guth continued,

"I wonder if we can grow this in this country?

He said. If this could be done, it would be a great contribution.

Afterwards, Jin and the others witnessed an experiment in which the solution was boiled down and concentrated.

"Oh, it's so bright!

The concentrated solution emits light more brightly.

"Kuh, it would be great if we could apply this to a nightlight.

Saki looked happy.

"I wonder what kind of substance it is?"

< magic can only investigate what it knows, so it is impossible to find out about unknown substances.

"All I know is that it has nothing to do with free magical elements (ether)."

With Aal's help, he was able to determine that it was not a magical phenomenon.

"That's good news.

As Jin was looking for a light that was not caused by free magic element (ether), he was grateful for this information.

* * * * * *

After eating lunch with Saki and Goose, Jin and Erza left the Eschenbach house.

"Now we know where the emergency lights are.

"Hmm."

The two face each other in Jin's workshop at the laboratory on Horai Island.

"...... is not only for spaceships. It will be good for the world."

"Yeah, we're going to have to do a lot more research for that. We can't just let Saki do it.

<, they will be able to get cheap lights.

Apart from Goose, Jin intends to do the same on Horai Island.

"Even if we talk about cultivation, we have to find the best conditions for it.

Is it better to keep the environment the same or change it?

If so, what will happen to the content of the phosphorescent substance?

There are many things to be done, but I have to leave this to the old man.

"Brother Jin, aren't you a little impatient?"

Erza asked a little worried.

"Yes, I may be a little impatient.

"...... spacecraft development is going well. On schedule, no, a little early. So why?

Jin answered this question with a sad look on his face.

"I'm just worried."

"Worried?"

"Yeah. After all, even in my former world, space development and space travel were still in their infancy. I'm trying to make it happen with the help of magic. I guess it is ...... because it is an uncharted territory where there are no models at all."

"......, yes."

Erza nodded in agreement with Jin's explanation, although she was still a little unconvinced.
