Magicraft Meister Part 1

The term "homeostasis" is used to describe the maintenance of homeostasis.

The term is often used to refer to the self-preservation function of living organisms.

It refers to the action of maintaining a constant body temperature and a constant blood pH level by sweating when it is hot and shivering when it is cold.

In rare cases, this action can be translated into maintaining a constant environment such as room temperature and humidity.

And Jin had come up with the idea.

"Feedback, or ......".

If the temperature rises, lower it; if it drops too low, raise it. The same goes for humidity.

When the oxygen level goes down, it goes up, and when it goes up too much, it goes down.

Jin was trying to create a magi-machine with these functions.

And this is a technology that can be applied not only to maintaining the environment inside a spacesuit, but also to the inside of a spaceship.

"If it's just temperature, you're using a thermostat. ......"

The key to this technology is the sensor.

This means that sensors that detect temperature, humidity, oxygen concentration, CO2 (carbon dioxide) concentration, etc. as accurately as possible are needed.

This is a very difficult task for Jin.

"Oxygen and carbon dioxide can be detected by applying the magic tools of ," he says.

Jin thought it would be possible to detect dangerous gases.

"Temperature and humidity. ......"

Temperature is especially difficult. Humidity only oscillates between 0 and 100 percent, so I think it can be done by applying <>.

Temperature, however, can only be known relatively since there is no standard to quantify it.

For those who cannot use magic, humidity can be known as <>.

However, there is no such a reference point for temperature, so it must be set by the magician.

And that < is difficult. The difficulty is so high that even Jin could only set <, and even if he did it 10 times, he would not be able to get the same value.

"I guess 0°C and 100°C. ......"

"It is difficult, father."

"...... something on your mind?"

While Jin and Reiko were having a hard time, Elsa came over to them.

"Hey, Elsa, how are things in the village of Kaina?"

She was supposed to be teaching the children for the first time in a while, along with Meane.

I'm done. ...... Jin, no way!"

"What?

Jin couldn't help but look at the window of the workshop. It was dark. It was definitely past 6 pm.

Considering the time difference, Erza must have left the village of Kaina around 4:00 p.m.

"...... was a close call."

This line is quite natural for Jin, who is so absorbed in his work that he does not even eat his dinner if left alone.

"I have to be careful, Reiko," he said.

"...... No, I was going to force your father to take him to dinner at 7:00 PM."

Reiko seemed to have known that, and she was going to wait until the last minute to interrupt Jin's deep thinking.

Luna and Soleil had already prepared the meal, so Elsa and Jin joined them at the table.

"The rice at Horai Island is delicious.

"Yes, it's delicious, isn't it?

"Thank you."

Soleil, who was in charge of the dinner, bowed her head.

The staple food in Kaina Village is barley (bread and porridge), so the rice is the best in Houraishima.

Tofu made from bittern extracted from seawater and soup stock made from kelp found by the mermaid team from the northern sea are also unique to this place.

After-meal teas are available in a variety of teas, including Teh Kahi, Perhia, green tea, black tea, hoji tea, and genmaicha (brown rice tea).

In this case, I chose hojicha.

"...... delicious."

Sipping the tea, which had been cooled down to the right temperature, Jin talks to Erza.

"About earlier, I was wondering how to make a temperature sensor.

I omitted the part about what it would be used for, but Elsa seemed to have a vague idea.

"You were wondering why there is no ...... standard?"

That's what I'd expect. Erza is already a top-notch magical engineer (magi engineer), so she seems to have an idea of what Jin is worried about.

"Temperature is difficult to control without a reference point.

"Yes, that's right."

"...... is indeed difficult to control."

After that, Elsa also became silent and thoughtful.

"The point is, we just need some criteria,......."

At this point, Jin came up with an idea.

"Right, a standard!　We can memorize the conditions of 20 or 30 degrees Celsius in the magi crystal and use it."

This idea is similar to the one used in electric circuits, where a reference voltage is created for comparison.

"Well, that's doable."

"Now we just need to figure out how to record the temperature ......"

This is another difficult problem.

Humidity can be defined as water molecules in a certain space, but when it comes to temperature .......

Jin and Elsa ponder again.

"Is a thermometer the only way? ......"

That's where we end up.

"The simplest, or rather the easiest, way to make a thermometer is to monitor the thermometer's scale with the golem's eyes and make a judgment. ......

I don't think that's very smart.

"Let's see if we can't make a thermometer by some other method."

In modern Japan, there are various types of thermometers other than those using mercury and alcohol.

There are thermocouples, which are made by joining two different metals, and radiation thermometers that use infrared rays.

"Oh, yes, infrared rays!"

Also known as heat rays, they are electromagnetic waves with wavelengths longer than 700 nanometers, and unfortunately humans cannot see them, but Reiko can. What color they are, I can't imagine.

But, indeed, Reiko and other automata and golems can < them.

"We can make them remember the of the room temperature and control them to maintain that ."

"...... Jin brother, it's too hard to understand."

Erza is unable to fully understand Jin's explanation.

"Oh, oh, I'm sorry. ......Well, maybe it's time for Erza to have the final stage of <>."

After several , Elsa now has the knowledge of a high school graduate in modern Japan.

The final stage is the specialized knowledge including miscellaneous knowledge that Jin has carefully selected.

This includes knowledge obtained from science fiction novels, anime, and manga, knowledge learned from newspapers, TV, and other media, and knowledge learned in training after entering the workforce.

The knowledge that Jin had carefully selected from among them as being worth learning was the final stage.

Jin took the magi crystals of all attributes from the vault attached to the wall and presented them to Erza along with another magi crystal.

"Erza, this is the final stage of knowledge. Will you accept it?"

Of course, this is not all the knowledge Jin has. It does not include knowledge that he does not need to know.

"...... Yes, with pleasure."

Erza accepted the magi crystal without hesitation, knowing that this would allow her to help Jin even more.

She then immediately transfers the information to another unrecorded magi crystal.

"<>"

Thus, the information converted into Erza's own magical patterns can be read directly and taken into her brain.

"<>"

Erza transfers the information from the Magi Crystal into her own head.

"......"

The carefully selected knowledge is not a big burden, but even so, Erza is a little confused by the sudden increase in knowledge.

However, she is calmed down with time.

"......Thank you, Brother Jin. I look forward to working with you in the future.

"Yes, Erza. I will always be with you.

"...... nn."

Erza nodded her head with a slight blush on her cheeks at these < words from Jin's mouth.
