Magicraft Meister Part 4

On the morning of March 26th, Jin decided to go back to Reuthert's house with Goh and Rubina.

He had been away for a long time, and he felt that Merce would miss them.

< back as she came.

<.

"Well, I'll be back."

Jin bade farewell to those who had seen him off.

"Jin-dono, thank you for everything you have done for us. Have a safe trip.

Mr. Goh, Ms. Rubina, I will see you again.

"Jin, I'll do my best to show you my machine next time I come back.

"Jin-san, take care."

"Mr. Goh, Ms. Rubina, you guys do your best."

After exchanging a few words of their own, Jin and the others boarded the .

"It's been a great experience, hasn't it?

"It was fun, wasn't it?"

Goh and Rubina are thinking back over the past few days.

"We miss you, Mel.

"Yes, we do."

We have a lot to talk about.

< flies towards the Shoro Kingdom.

The distance is more than 600 kilometers, and it will take more than three hours at a speed of 200 kilometers per hour.

The time difference is approximately two hours, so a that leaves at 8:00 a.m. will arrive in Leuthart at 9:00 a.m., three hours later.

"The time difference is strange."

"It makes sense in theory."

"Well, if you take a look at the Ars Ritual, you can get a little more of a sense of how time differences work."

Jin said, "It's easier to understand if you try shining light on a three-dimensional ...... or rather spherical ars gi and try various things.

"Oh, maybe."

"It's hard to understand if you only look at a flat map."

Even if you calculate the time difference from longitude and latitude on a map, you may not be able to get a sense of it.

Goh and Rubina took out the ars belli that was installed in the < and began to play with it.

Jin let them play while he looked out the window.

A short distance away, he sees the <> flying alongside the <>.

(Part of the wind magic is not moving the air. ......)

Jin does some kind of thought experiment in his head.

(Then, what is the purpose of the <> for? ...... is to prevent the pressure inside the engine from increasing too much.)

The inner walls of the engine are pushed by the <>. Jin thinks that if the jets were closed, the pressure on the engine wall would increase even more.

(But one of the advantages is that the wind does not blow out of the engine. ...... but is it really a viable engine in the first place?)

This idea is becoming more and more interesting.

(...... Let's consider a much larger room. () If we start a MagniAero rocket engine fixed in the room, will the room move?)

The propulsive force of the < rocket engine is the <> which is shot at the closed end of the engine.

It is the same as shooting a <> at the sails of a sailing ship.

(And the flow of wind...... air generated will disappear once the pseudo-molecules of air produced by the magic disappear. In other words, the pressure becomes zero.)

When the jet is not closed, <> = <> + <>.

It is a fact that the wind is certainly present and pushes the atmosphere, even though the time of the jet is only for a moment. That is, it adds to the propulsive force.

When the jet is closed, this term disappears. In other words, = .

Although slightly less efficient, the fact that there is nothing to be injected means that the engine can be expected to be quite quiet.

.

This is a different principle from the <>. That may have its own uses.

We will experiment with it in the near future.

< is on the roof of Reuthert's house. landed on the airfield.

was left in a rental warehouse, and Hope returned to with her own transporter.

"Welcome back, Ruby, Mr. Goh."

When I arrived at Reuthert's house, Merce greeted me.

"Welcome home, Jin-sama."

"Welcome back, Rubina-san, Goh."

Of course, Daikie and Cocona also greeted us.

And then.

"Welcome home, Rubina."

And Rubina's grandmother, Amanda.

I'm home, Grandma!

I hope you didn't give Master Jin any trouble.

No problem!

I don't trust you, the way you're talking to me.

With that conversation, we all descended from the roof and went to the living room.

This is the most comfortable place in the house.

Yenny, Märze's personal maid, made a pot of sencha green tea.

"Oh, it's delicious!

Jin, a tea lover, tastes the familiar taste. The familiar taste of tea is a welcome relief. It makes him realize that he has come home.

"You know, Goh and I, we got certified as <> at the <>!

"Oh, I didn't know that. You did a great job!"

"Mr. Gou, Ruby, that's great!　Congratulations!

"Goh, you did a great job. Congratulations!

"Congratulations, Rubina!"

Goh and his friends report that they are now .

Daikie, Cocona, and Merzhe gave their compliments.

"Jin, thank you for all your hard work.

"Yeah, I'm a little tired after everything that happened.

Jin was Jin, and Erza gave him a compliment.

By the way...

"By the way," she said.

"There will be a spring garden party at Miyagi in the near ...... future."

What?

I received an invitation yesterday.

In this case, the garden party is, in short, a .

It is a social party held for invited guests in the gardens of the Shoro Imperial Palace.

"Oh, for Daikie and Cocona..."

Jin, me, Gou, and Merce.

"What?"

Jin was surprised, but when he thought about it, Goh was a legitimate son of the Nido family, and Merce was a member of the emperor's family.

It is not surprising that they received invitations.

Goh also needed to make his debut in the social world since he had become a nobleman, and Erza thought that the would be a good time for him to make his debut.
