Jin told Hope to return to Horaijima and took Reiko to Loisart.

They left Jin's workshop in the basement.

"Now, what are Goh and Rubina doing?

When they went above ground, they found the assembled Nile VIII.

"Oh, it's done!"

"Oh, Jin-sama!"

"You came back via the ...... warp gate, didn't you?"

Rubina noticed first, followed by Goh.

It seems that the two were checking the completed .

"It's a nice finish.

"Thank you very much!

It's a great relief to hear you say so.

It seems that he was concerned about Jin's evaluation.

"Tomorrow, you will take this to Horai Island for a test flight, right?

"Yes."

"I'm looking forward to it."

"I'm thinking of ...... how to transport it."

Oh.

Oh, ......

I hadn't thought of that, they both said.

"Well, there are a lot of ways to go about it. <."

Jin thought for a moment,

"But let's use the transfer magic circle.

Jin thinks for a moment and then says, "But I think we should use the transfer magic circle.

If the magic circle is large enough, even large objects can be transferred.

It takes time to prepare for the transfer, but that can't be helped. It is not a matter of time.

"Tomorrow morning, I will draw a magic circle in the garden. The island of Horai will be the host. Is that all right?

Yes!

Yes, please.

Okay.

That night, neither Goh nor Rubina could get to sleep. .......

* * * *

The morning of the 13th.

At 6:30 a.m., Gough and Rubina were in the garden of Reuthert's house after having finished breakfast.

"You two are early.

Jin-sama is even faster than you.

"I had to prepare the transfer magic circle.

The majority of the drawings, however, were done by Smith.

The maximum diameter of the magic circle is 30 meters, and the transition circle is 15 meters, so it is better to leave it to the > than to have Jin draw it, because it will be less distorted.

Jin wrote down the parameters and checked them.

"Is it already done?"

"Yes, it's ready. We can put it on the transfer circle, and it will work anytime as long as we apply the magic power for activation of the magic circle.

Okay, let's go!

Are you ready?

Yes, Master Jin.

I see.

Goh and Rubina both said they were ready, so they had <>99 and Reiko carry the aircraft to the transfer circle.

In order not to step on the magic circle, we had them carry it while floating with the <>.

Then, they were transferred.

On the Horai Island side, there were <>97 and 98, and they informed me that they had received the message with the built-in manacam.

"Okay, let's go."

"Okay, let's go."

Yes!

We move through the warp gate to Horai Island. This time, the golem unit will also participate in the experiment, so it's a pity that we can't take Melze with us.

* * * * * * * * * * * * * *

When Jin and the others move to Horai Island, < is already on the runway.

Standing beside them is Sky1, a veteran of many such test flights.

"We're all going to use the same controls, right?"

Yes, Master Jin.

Do you have any special equipment?

An emergency parachute.

This equipment is not used by the pilot, but for landing the aircraft safely.

It is not particularly difficult to operate, just pull the lever.

If it proves to be usable enough, the pilot disconnects it, starts the engines again, and comes back.

And the parachute, which would probably fall overboard, would be retrieved by the marine unit.

"I see. ...... sky1, I'll take care of the test flight."

"Yes, sir, I'm on it."

Sky 1 is equipped for a test flight.

This time it's a human flight suit.

Since a human astronaut will be flying the aircraft, these preparations are necessary.

In addition, a gravimeter is installed separately. It is to record what kind of G forces are applied during the flight.

And a transporter for escape in case of emergency. I've arranged for you to exit in front of the institute.

Okay, let's go.

Sky1 gets into the , closes the windshield, and turns on the manacam.

From now on, they would communicate with each other via manacam.

The engine noise is relatively quiet since there is no explosion.

Air is gushing out of the jet at the rear of the fuselage with great force. The air is pseudo air and dissipates in less than a second.

The jet of air increases in intensity, and <> begins to glide.

Whoa!

"Go!"

The Nile VIII glides smoothly down the runway.

The runway is 1,000 meters long, but it does not take up all of the runway. After about 600 meters, the plane takes off.

It flew!

"It flew!"

<

The aircraft continues its ascent, and soon disappears from sight.

However, the old man is tracking it with his < and we can see it from the control tower at the end of the runway.

The old man can also receive the manacam, so Jin, Reiko, Goh, Rubina and the others are inside watching <>.

<

flies through a cloudless blue sky. The observer cannot feel the speed because there is nothing to compare it with.

<600 km/h......650 km/h... ...700 km......750 km ......>>

Although it has the same two engines, it has less power than Jin's <, so the acceleration is slower and the top speed seems to be a little lower.

<

"Well, that's a good point."

"I don't think I can go Mach. ......"

"Rubina, wind magic is basically impossible because it doesn't exceed the speed of sound."

"That's right. ......"

Since the speed of jet cannot exceed the speed of sound, it follows that airplanes cannot exceed the speed of sound either.

And < deploys <>.

This is basically deployed in the direction of the nose to avoid adiabatic compression of the air.

This is done because the <> system cannot take in air if it covers the entire area.

This has not been changed even in airplanes equipped with <>.

This is partly to allow air in for cooling, but also because the directional rudder, elevator, and ailerons are no longer usable.

It is enough to prevent adiabatic compression.

Thus, Sky 1 tested the < one after another.
