In the carriage on the way to the castle,

"By the way, I heard that you met with Viscount Charnedo last year.

It was when I visited the Kingdom of Klein with Rhodes.

"Yes. The gardener of the Viscount Charnedo family, ...... was involved in an accident between a carriage and a golem car, wasn't it?　...... was involved in an accident between a carriage and a golem car, and I helped him out.

Paula had questioned whether it was necessary to learn science, so he had given his opinion on the matter.

"Oh, that's ...... true, the <> was still in power at that time."

As the Minister of Magical Technology, Corwin Raqqa Kiddo, who is from a technical field, he says that he felt awkward every day.

"Yes, it was. Then came the great invasion ......."

Meanwhile, Zion D. was talking with King Mericolance I of the Kingdom of Klein.

"You are always so young, Lord Theon. I envy you.

"Well, what do you say to such an old lady?

"No, no, I'm not flattered."

Deus ex machina stares silently at the castle.

They arrive at the castle. King Mericarance I moves with ease through the line of Kingsguard knights on either side of him. Jin and the others followed.

First, only Jin, Reiko, and Makina are taken to the reception room. Theon heads for his office with the king.

"Jin, I'll take care of the contract regarding the rental of the bus," he said.

He leaves the room.

In the reception room, Jin and Makina are served tea.

"Oh, it's Kaina tea.

It tastes familiar. The tea was made from the leaves of the perhya tree that grows in the village of Kayna.

<

Jin liked the taste of this tea.

Was it by chance or by design that he had given it to , that is, ? I couldn't tell.

"Please wait for about an hour until dinner is ready.

The lady who served the tea said this and left.

(An hour? ......)

This kind of laid-backness is frustrating when you are used to the modern Japanese lifestyle where every second counts, but it is normal in this world.

Jin was once again reminded of this.

And then...

"Excuse me."

Two young women entered the room in place of the maidservants. By the way they were dressed and their mannerisms, they seemed to be the daughters of noblemen.

"My name is Norma Dope Harcourt.

My name is Catherine Piller Grosin.

Jin Nido.

Deus ex machina.

They're both countesses, if you must know.

I've just started studying magical engineering and would be very grateful for your help.

Norma is the calm type. She has light chestnut-colored hair cut at her shoulders, somewhere between semi-long and bob.

"Thank you very much!"

Catherine seems to be the bubbly type. She has dark blond hair and blue eyes. Her hair was pulled back in a ponytail.

If she wants to hear about magical engineering, Jin has no objection. Makina has the same attitude.

"Sure. Well, first, I'd like to know what level you two are at. ......"

Jin searches his pockets for something appropriate. But what he finds are two Magi Crystals. This is not a good practice for forming. But...

"Can you tell me what you know about these magi crystals?"

Jin put one of the yellow Magi Crystals on the table.

"Oh, it's a magi crystal with an earth attribute!"

Catherine answered first.

"Then, what about this?"

Jin took out a green Magi Crystal.

"It is a wind attribute Magi Crystal (......)."

This time the calm Norma answered. She looked at Catherine and gave a small nod. Jin thought that Norma seemed to know what she was doing and had given the quiet Norma a flower.

After that, as a matter of course, Catherine talked to Jin and Norma talked to Makina to kill time.

Their enthusiasm for magical engineering was genuine and not something that was merely superficial.

However, they were only beginners at the level of a university professor talking to a kindergartener.

However, both Jin and Makina were polite.

"So, what would you like to talk about?"

"Yes, about materials. In particular, the difference between ordinary materials and <.

"Okay. Okay, let's start from here. Explain what you know about the <.

"Yes. It is a material that can be strengthened by magic power.

Hearing this, Jin sighed in his heart. He knew that the current educational content had fallen behind.

"Yes, that's not a mistake. But it's not enough."

They probably haven't even learned the concept of . Jin thought that they would not be able to understand the essence of <> even if he explained it to them.

Then, Jin said,

"What you just explained to me is a part of the nature of the <. We need to think about why <> has such properties.

I will say.

"Why do you say ......?"

"Yes. That is the starting point of <>. The question that every human being has, <>question. The study of is to try to find the answer to that question.

"Science......"

"The <> was hostile to science. That's probably why education about science in this country has taken a back seat."

Jin explained to Catherine, chewing as he went on.

"Now then, let's get back to the . < so easy to pass through magic power? Why is it easy to be strengthened by magic power?

"Yes, please!"

Jin explained the principle without explaining the molecular structure. .......

Meanwhile, deus ex machina.

"I'm having a hard time getting the < to work. ......

"That's first of all because you don't have enough images."

"Image, is it?"

Makina nodded.

"You might start by drawing a perfect circle or square as accurately as possible without using a ruler.

This is also good dexterity training, Makina continued.

"Ah, so that's another way to do it. If you practice <, you'll run out of magic after less than 20 times. ......"

Yes, that's right. It is not limited to <>, but image is especially important for engineering magic. <, and it is a good idea to do this on a regular basis."

Makina even advises that the easiest way is to close your eyes and practice drawing various shapes ......, preferably three-dimensional ......, in your mind.

"Well, that's a good way to ...... thank you."

Reiko was taking care of the four of them by pouring them more tea. Well, Makina never gets thirsty, but that's part of the act.

And so it went on until the maid of honor came to inform them that dinner was ready.
