Jin, Eira, Katya, and others were just about to put together .

"Well, it was a success!

"This plane is very promising. Just because of the aircraft.

The members of the <> returned, chatting amongst themselves.

"Mr. Jin, welcome to our laboratory.

First, Rasnat Heilbronn, the head of the laboratory, greets Jin.

"Thank you for everything you did for me the other day.

Jin's doppelganger says that he has come to check on Katya.

"No, I hope I was helpful."

"Of course it was!"

Rasnat Heilbronn loudly affirmed Hitoshi's humble tone.

"The mini-golem we experimented with today is an adaptation of that. Please have a look!

he said excitedly, showing Jin a small golem 40 centimeters tall.

"Wow, it's a nice piece of work, isn't it?

Jin was honestly impressed.

I don't know how many of them there have been, but this is a marked improvement over the first prototype.

The smoothness of the body line tells us that the movements will be smooth, and the finish of the joints suggests that the movements will be reliable.

"Thank you very much!"

Rasnat Heilbronn is in a good mood when Jin praises him.

Let's see it in action. ...... Groma, please."

"...... yes."

Gloma Trey smiled a little,

"<>"

he said, uttering the key word.

Jin guessed that Groma seemed to have the highest priority in the order of command.

"Hi."

The activated golem replied in a slightly high-pitched voice.

(In that case, is it using artificial vocal cords for its vocal part?)

(I wonder if the artificial vocal cords are used for the vocal part.) Like a human, the breath shakes the vocal cords to produce a voice.

Since it emulates human vocalizations, it is easy to create and the voice sounds natural.

However, a drawback is that the smaller the golem is, the higher the pitch of its voice becomes.

There are also the synthetic voice method and the speaker method.

The synthetic voice method is like a virtual singer software that allows you to sing a song you have composed yourself, to use a modern Japanese example.

The speaker method, on the other hand, is not so close to ......, but it is a bit similar to the voice guidance system of some car navigation systems.

The small golem, once activated, performed the self-check pattern in one step.

Just from that alone, Jin sensed that he had come a long way.

"This is amazing. You can see the difference in its movement.

Jin praised him again.

Really, smooth and quick movement deserves recognition, he thought.

"Well, I am honored to receive such a compliment!

Rasnat Heilbronn was in a good mood and asked Jin to shake his hand.

"Are we making progress, little by little?

"Yes, of course."

Hitoshi replied without flattery.

"Well, I'm glad to hear that. Would you like to join us for lunch at ......?"

And so, Jin had lunch with the members of the .

Meanwhile, back in time, Erza was visiting the medical team.

This is a temporary name.

It is currently classified as a because of its small size, but it will be renamed as in the near future.

There is also a under the medical group.

On this day, Elsa is being entertained by the deputy director, Mei Shai Joey.

Incidentally, they are called <<3Y>> because their name, middle name, and family name all end in <>. ......

"I look forward to that day.

"I am looking forward to that day, thanks to Elsa's guidance.

Sipping tea in the back of the medical lab, May bows to Elsa.

"The other day's lecture has helped me to raise my awareness a lot," she said.

"I'm glad to hear that."

At this point, Elsa asked a question that had been bothering her.

"What happened to the villagers we rescued?"

That was only four days ago. He was curious about the progress of the people he had treated.

"Yes, they were all safely returned to their villages. They are all in good health.

"I am so relieved to hear that."

Elsa was relieved to hear that.

She had been worried because she had not been able to see her patient until the end.

"That juice is very effective as a nutritional supplement, isn't it?

He was referring to the Persica juice that Jin had left behind.

"Yes, I made it in cooperation with my husband.

"I see, I'm ...... convinced that your husband is a Magecraft Meister."

Mei Shai and Joey nodded deeply.

In <>, Persica and other fruit trees are grown for research purposes, but they do not contain as much free magic element (ether) as the ones in Horai Island, and therefore are not as effective.

Then, Elsa said

"If we store the aged ...... for a long time in the <>, the effect should be high," she said.

He then explained one way to do this.

<> is a storage unit with a ratio of free magic element (ether) to air inside of 80 percent or more. By storing it, the purity of magical materials is increased.

Of course, thanks to the high concentration of free magic element (ether), the internal materials do not decompose.

In addition, Persica juice from Horai Island is grown and collected in the special environment of Horai Island (the singularity of free magical element (ether)), so it has a higher affinity with free magical element (ether) than the ones from other places.

Elsa kept quiet because she could not imitate them.

"Thank you very much for your instruction!"

Mei Shai Joey bowed her head happily.

And now to the main topic of the day.

"Today you are going to teach us these various medical skills and knowledge, is that correct?"

Yes, that is my intention.

"Then, I would like to limit the question and answer session to those who have questions, wouldn't you?

"I'll leave it to you."

Thus, Elsa's education at the Medical Research Institute of <> was to take another step forward.
