"......"

"This is interesting."

"This is amazing!"

The disguise that Reinhardt, Erza, Bina and the others had already used when they arrived was sufficient, but the warp gate in the basement could not be shown, so it had been sealed in advance.

Several men and women are now looking around the dummy laboratory with great interest.

The dining room, the workshop, and the living room.

The workshop in particular was the center of attention.

The first of them is Ernest, the third prince of Egelea. His fiancée, the third princess of Klein Kingdom, Rieschen, is surprisingly attached to Anne.

Or perhaps not so surprising. She is probably concerned about Anne, who is the same ...... model as Tia, her nanny, although the exact ...... lot is different and the actual sister machine is Refa.

"I wish I could study magical engineering in a place like this."

Ernesto mutters innocently, "I wish I could study magic engineering in a place like this.

"I remember you liked golems.

The one who spoke to him was the Shoro Imperial Lady.

"Ah, Your Majesty. Yes, I love golems and automata!

"Hmm, you and Jin-dono seem to have something in common, don't you?

The Empress smiled softly.

"Hey Jin, can you teach me engineering magic?"

Ernesto suddenly said something like that.

"What?"

"Even if it's just for a week, I want Jin to teach me. ......"

"......"

However, Ernest is royalty, and Jin can't give his consent here and now.

"Ernest-dono, Jin-dono is in trouble.　It would be better to ask for your father's approval first.

Again, the emperor followed up.

"......Yes, that's right. Yes, I understand."

Ernesto meekly withdrew.

"Jin, when your father gives you permission, you will tell me!"

"Oh, yes."

Jin could not help but nod in agreement.

< and drag the Death Sea Serpent they have defeated, a was running alongside, carrying the guests.

"But it's quite a sight to behold, isn't it?

"What kind of material will the Death Serpent be made out of, Master Machina?"

Well, bones are strong enough to be used as handles for swords and large knives. Fangs are even tougher and are used in the same way. No one eats the meat because it smells bad. We have to incinerate them.

Everyone listens with interest as Makina explains.

"The skins are resilient and strong, so they are used to make leather armor, sword sheaths, and in rarer cases, parts of ships called in the Potlocks of the Kingdom of Elias.

"Oh, these are watercraft made in Marcia's workshop, aren't they?"

Godfrey, Prime Minister of the Kingdom of Elias, who was on board the ship, spoke up as if he had just heard what I had to say. Makina joined in.

"Ah, yes, that's right. Jin is processing the parts and distributing them wholesale.

"Oh, is that so?"

She did not seem to have that much detailed information. It is understandable in the Prime Minister's position.

"As a material, it's just above the middle level. It is more than sufficient for daily use.

Makina says this, and Prime Minister Godfrey looks somewhat dismayed.

"No, only you people would call this Death Sea Serpent a top of the range weapon.

"Indeed.

King Cesar agreed.

"I hope to be friends with you for a long time."

Prince Arthur said.

"Yes, I don't like conflict either. As long as the world is at peace and I can do my favorite research in magical engineering, I'll be happy.

"Oh, so you share the same opinion as Gin-sama."

King Franz Rotaro said with interest.

"Yes. Technicians like myself and Jin cannot understand the desire to rule the world at all.

"I see. To each his own, I see.

Prince Arthur nodded his head in admiration.

< is speeding through the water at about 30 kilometers per hour.

Prince Arthur looked out the window,

"I'm a little ...... envious of you who can see such a world," he said to himself.

he muttered to himself.

The flying slowly lowered its altitude and snatched the directly over the ocean.

"Land, sea, and sky. <'s technology is bottomless."

Marquis Florenziano muttered in a deep voice.

"Sir, all of this has its roots in one thing.

Elsa said to the Marquis.

"One?"

"Yes. It can be summed up in one short word: the realization of a dream.

A dream.

A dream, yes.

"Dreams. ......"

A dream to run faster than the wind across the land.

I dream of traveling freely across the oceans.

I dream of flying through the sky as I please.

"I'm halfway there, but..."

"We're halfway there. ......"

Those who heard these words sighed.

Is this the halfway point for Jin?

He said, "Progress stops when you are satisfied. He also said that the best work is always the next one.

So that's the next best thing.

The Marquis of Florenziano closed his eyes and said in a quiet voice, "I see.

I'm always up for a challenge.

"I am always up for a challenge."

<

Forgetting to use the first person, Jin muttered to himself.

The moment you think you have reached the top, the retreat begins. Therefore, I want to continue to be a perpetual challenger. That is my current goal.

I see. So that's the mindset of Jin.

"That's just like you, Jin."

The soft smile of the empress loosens Jin's heart.

"Normally, I only talk about things like this with Erza.

That's why such an unnecessary line came out of her mouth.

But it was pleasant for Jin.
