On the same day that Mericarance I, King of the Kingdom of Klein, was visiting the village of Toka, that is, November 14, the island of Elektra, one of the Pleiades Islands in the southern sea of the Kingdom of Elias, was discovered by the king of the Klein Kingdom, Mericarance I, in the village of Toka. Electra, one of the Pleiades Islands in the southern sea of the Kingdom of Elias.

In other words, at the headquarters of the Nostalgia Party.

"So there's nothing suspicious about Markkonen so far.

<

"Yes, Elena-sama."

The person on the other end of the line is Leelia Madagas. She is a female engineer who is a senior member of the Kaiso-kai, and usually gathers information under the cover of the .

"If we get any deeper into this, it will look suspicious, won't it?"

Yes, I think so.

Then we'll have to ...... meet her in person.

Is it Elena-sama?

Yes, that's right.

Isn't it dangerous?

I don't think so. ......

Marconen does not seem to have any ambition or evil intentions, and Elena has been strengthened by Jin.

In addition,

"I'm also taking a golem to escort me."

He tells her that he will also bring a golem to protect her.

"Yes, I understand. We will do our best to support you.

"Elena of Nostalgia is coming to visit us.

And they want to exchange technical information with her, the Elias Kingdom's state-run magic workshop is informed.

"Oh!　Elena-san is coming herself?

I heard she's a beautiful girl.

The workshop was abuzz with talk of her arrival.

Is it the Nostalgia Party?

"Yeah, you don't know Marconen?"

No, I know him somewhat.

He was thinking about something as he answered.

* * * * * * * * *

On November 17, Elena, Arum Pitt, a mid-level engineer, and two general-purpose golems as escorts arrived at Borgia, the capital of the Kingdom of Elias, by airship at 1:00 p.m. It was one o'clock in the afternoon.

"Oh, it's still beautiful, isn't it?"

"It's as beautiful as ever. ......

Elena walked straight to the door and shook hands with Fiorina de Dorante, the Minister of Magic and Technology, who came out to greet her.

"Welcome, Elena!

"Thank you for the welcome, Sir Fiorina."

"You look so young, Elena, I envy you."

Well, thank you. Thank you for coming to ...... today.

Yes, I know.

Fiorina de Dorante has known Elena since long before she became Minister of Magical Arts and Technology, and she has taught her.

In other words, she is a , so she had an inkling of what the purpose of this visit was.

"At the moment, there are two research projects being conducted at the state-run magic workshop. and .

"I understand flying machines, but automata?"

Elena and Fiorina exchange words as they walk to the workshop.

"Yes, that's right. Apparently, some of the technicians are motivated ......."

"You mean, you saw the automaton that newcomer Markkonen has with him?"

Yes.

Yes, I'm interested.

Soon we arrived at the workshop.

"Welcome, Elena!

"Welcome to the workshop, Elena!"

Amidst the welcoming voices, there was only one person who stared at Elena as if observing her. It was the well-known Marconen.

After the welcoming voices had died down, Elena opened her mouth.

"Thank you all for the welcome. I have come here today to talk to you about the flying machines that are being developed in many countries.

This is quite natural, so no one thinks it strange.

"Then, please come this way."

Fiorina, the Minister of Magical Arts and Technology, who was the highest ranking official in the company, led Elena and her group to a reception room in the workshop.

"Yes, ...... Benitoa, Ralphart, and Marconen, please come."

The Minister of Magic and Technology, Fiorina, appointed a female technician, a male technician, and a new technician who was the talk of the town.

After the clerk has finished distributing tea to everyone, the discussion begins. By the way, Elena can also drink tea and can judge its taste <.

Since it would be a formality for both the host and the hostess to be harassed if only one person is not offered tea, Elena decides to drink the tea offered to her.

I'm going to stop talking now.

"Now, let's get down to business.

The minister of magic and technology, Fiorina, is the facilitator of the meeting.

"First of all, Elena, please tell us about the flying machines.

"Yes. ...... The most popular means of < at the moment is probably the balloon. There are hot-air balloons and light-air balloons, but I think light-air balloons are more common.

Balloons are not very maneuverable and are used for defense of towns, castles, forts, etc.

Balloons that float on helium are called light balloons, and they have become the main type of balloons because they are easier to use than hot-air balloons, which require a heating system.

"The latest development in ballooning is the blow floater, which is a type of balloon that uses wind to float. This was developed by Mr. Maricka of the Nord Federation, and its function of <> and <> are completely separated, making it simple to maintain and manufacture.

So far, everyone knows this, so I listen in silence.

"But there is a drawback to it. Do you know what they are?"

This question was answered by Markkonen.

"Forgive my presumption, but I have to say something. ...... is that it is < to make it larger."

After answering in a few words, he took a breath before continuing.

"The reasons for the difficulty are that the larger the size is, the less efficient it is, the less strong it is, the less maneuverable it is, and the more vulnerable it is to the wind. ......

"I see, so that's your opinion. Do you have any other opinions?

"Yes, I do."

The female engineer, Benitoa Ruston, raised her hand and opened her mouth.

"I don't think we can say that larger size is a problem, because we can deal with it by changing the material. I think that we should solve the problem of the increased consumption of mana by the larger size of the product.

He pointed out that since mana tanks and mana drivers are generally used, there is a problem of replenishment.

"I see. But that can be solved by using an "ether converter.

At this point, an unexpected word came out of Marconen's mouth.

"An ether converter?

Elena interrupted.

"Mister Markkonen, can you make an ether converter?

"Yes, of course I can."

This answer surprised everyone present, not to mention Elena.

"Where in the world did you get this technology ......?"

Alm Pitt couldn't help but say.
