It was a long time ago, in the year 3650 of the continental calendar.

"I guess we need to move a little faster after all.

Marikka of the <>, the <>, was sitting on her golem horse, staring at the sky and muttering to herself.

"Oh, Marikka, what's the matter today?"

Marikka rode her golem horse to the home of the clan leader of .

There she met Zion, the wife of her longtime friend and clan leader, Belialus.

"Yes, I was wondering if I could talk to you about something..."

"Well, you can't just stand at the door and talk, so come in.

Now Zion is 263 years old and Marikka is 243 years old.

Both of them look middle-aged on the outside, since the northern people age about five times slower than the people of the Laurentian continent.

Thanks to this, Zion, who used to be a tomboy, has settled down and become a dignified clan leader's wife, while Marikka has lost the restlessness of her youth and has become a matured magic technician.

"So, what do you want to talk about?"

"About means of transportation."

Transportation?

Yes. ...... just to take an example, the weather is sunny and the snow is deep, so today's situation is easy to explain.

It's a little tough on the golem horses, isn't it?

"Yes, it is."

So there's the sky, Marikka said.

"The sky, you know. ......

"In the past, Jinsha ...... made all kinds of airplanes. I, too, want to make a plane that is appropriate for the Nordic Federation.

Theon smiled.

"I understand. You want me to budget for it, don't you?"

"Yes."

<

"Okay. You can do it, since you are Jin's disciple. You can do it.

"Thank you."

The food situation in the Nordic Federation had improved, and the economic situation had improved greatly.

Sion thought it was time to pursue his own culture.

"If we analyze the planes made by Mr. Jin, we can divide them into four types, can't we?"

"Yes, Marikka-sama."

Marikka's assistant is , an automata she has just made.

This is Marikka's best work, hoping for a relationship like the one between Jin and Reiko.

"A type of glider that flies by generating lift on its main wings as it is propelled forward by a propulsion system."

The Glider Golem, Skylark, and Albatross, which Jin made in his early days, are examples of this type.

"A so-called vertical takeoff and landing (VTOL) type that separates the levitator from the propulsion system.

The Pegasus 1 and Condor are examples.

"Balloons and airships that use lighter-than-air gases.

These are Conlon 2 and hot air balloons. Well, the Conlon 2 uses a <> in combination with a .......

The last type uses a <>.

Mainly spacecraft.

"Force field generators and balloons are no good. Generating lift with the wings also requires a runway and ......"

Marikka decided that it would be difficult to operate on the snow-covered ground.

"Then again, it would have to be a Vertical Take Off and Landing (VTOL) type."

By separating the means of levitation and propulsion, the aircraft could be a VTOL (Vertical Take Off and Landing) type.

"The problem is the engine, or ......."

I am familiar with the <> that Jin has built. But.

"...... is not so common."

Marikka's goal is to create a machine that can be handled by <>. Ease of maintenance and repair is also important.

The magical jet propulsion engine (Magijet engine) is unlikely to be maintained or fine-tuned by engineers of Marikka's current level.

"...... simple type," she said.

Marikka spent several days puzzling over this problem.

* * * *

"...... was done. ......"

After a few more days, Marikka built what would later be called a , or or .

What makes it different from the one Jin built is that it has a wider range of airflow.

"In terms of image, it's like inflating a paratrooper with wind from below," he said.

"Yes, Dr. Maricka."

Maricka explains to her students.

"In that case, let's call the air vent ...... for simplicity. If the air vent is small, you have to increase the wind speed of the airflow to keep the aircraft afloat.

According to Marikka's calculations, the weight of the aircraft, including the pilot, is estimated to be 200 kilograms.

This would generate winds equivalent to a major storm.

In order to reduce the wind speed, the wind volume should be increased, so they designed the Magi Formula to increase the diameter of the virtual nozzle to several meters.

The nozzle was made to be several meters in diameter.

Let's give it a try.

The prototype was completed a few days later. The test pilot was Hanako.

The location was a plaza on the outskirts of the clan territory of Shinra. The snow was about one meter thick.

The snow was chosen in the hope that it would provide a cushion in the event of a crash.

Hanako, be careful.

"Yes, Marikka-sama."

Hanako then boarded the prototype and started up the "blow engine.

With a distinctive whirring sound, the main wing, the umbrella, spread out. Yes, the <> wings were still in use at this time.

The plane slowly lifted off the ground.

"It floats!"

The prototype floated up to a height of about 3 meters above the ground, and began to move forward slowly, as if Hanako had activated the propulsion system.

The speed was about that of a person walking.

Marikka and her students watched with bated breath.

And then...

"Ah!"

"Ah!"

They saw a crack in the umbrella that serves as the main wing.

Naturally, the plane loses its support and crashes.

Hanako!

Marikka runs toward the crash site. .......

"............"

She is buried in the snow.

"Marikka-sama, are you okay?"

Hanako rescued Marikka.

She had not suddenly fallen, as Marikka had expected, and the snow was almost undamaged.

"Oh, thank God. ......"

Marikka hugged Hanako.

* * * *

The cause was definitely the lack of strength of the main wings.

Therefore, Prototype 2 was made with a <> umbrella.

This increased the total weight by about 15 kilograms, but this was more than offset by a 20% increase in the output of the levitator.

"It worked this time!

"Congratulations, doctor!"

Marikka and her students cheered.

In this way, Marikka was getting closer and closer to perfecting her blow floatation machine.
