The time now is 02: 20.

Ten minutes to the scheduled time of launch of the iron pile cannon. The countdown has finally begun.

The special warhead of the iron pile cannon we boarded, "Four Bullets", was shaped like a vertically elongated pen. Made of silver glowing metal, it is as long as 15 merte and about 1.5 merte thick. It seems surprisingly large, but only a small part of the tip portion about 5 merte can be ridden.

Near the center of the torso, they have wings for folded posture control, a mechanism to open left and right in the air.

"After being ejected, it rises vertically and moves to horizontal flight near an altitude of ten kilometres Merte. At that stage the sound speed (* approximately 1200 km/h) is reached. So the wings unfold and maintain their posture. And then… Fluid control that encloses the projectile continues to glide (…) by magical force, but further 'eruption devices' will begin to operate to earn distance."

The young tech officer who guided us will explain it to you.

Apparently, they're ejected at super high speeds like simple iron pile gun warheads, and they don't make ballistic flights to reach their goal. It seems to be a mechanism for being ejected at relatively low speeds, cruising (...) while maintaining some altitude, reaching the target.

Sure, otherwise it's an initial acceleration shock, and our bodies riding inside can't even have it.

"By the way, what is an 'eruption device'?... I mean, the magic propulsion agency?

I didn't know such an advanced thing was being developed. Some of this is due to sealing the use of search magic (Gogol) against state secrets, but with so much magic technology, it should be easy to put ashore battleships into practice...

But the tech officer gave a bewildered grin.

"That's the... It's primitive."

"What do you mean?

"I paint a magic circle with a bursting magic formula on a thin magic cloth and lay it on about 10,000 pieces. And by continuously blasting (...) with time difference, you pulse the shock waves and turn them into propulsion. Naturally, institutions are disposable."

"Oh, that's dangerous!?

Doesn't it seduce and dokan all at once?

"Yep... It was terrible at first. But after trial and error, it's almost safe now!

"Pretty much."

"It's steadily adjusted to burst every second. Bubble...... and unique shock and noise, so between us in the development team, we call it a bubble warhead or something, hahahaha"

"Hahaha!? Thank you for your valuable information…"

What a low-tech flying object, but now we can get to Dicamaran, eight hundred kilomertes away, in less than an hour.

As you slip into it, two seats made of light wood and leather line up left and right and six rows vertically.

Apparently, it's designed to hold twelve soldiers, but it's narrow and can't afford much. This time, as an emergency escape, six flying wine barrels will be loaded.

The six people on board and "Barrel" were linked by a leather bonding device.

This is for emergency escape in the unlikely event that the course of the "Four Bullets" is significantly off target or encounters an unforeseen situation.

I'm not comfortable with the sky in this Barrel, but the control formula I planted should allow me to safely descend to the surface while maintaining my posture.

The iron pile cannon is a longitudinal projection towards heaven, so naturally, the passenger's "Type 4 bullet" also stands upwards.

So we're sitting on our backs.

In the space at your feet, push the set of journeys Riola has prepared for you. It seems that there is also a tank of water considering that it will serve as a survival base for the first time, but it is installed between the rear-end injection device (...) and our crew. Whatever you think, it would be heat proof.

"I hope you fire soon..."

"Ha ha! Don't get excited......! Snoovel, let's go now!

Lu with a little nervousness and ergonotes while keeping the tension high.

At the beginning, I sat as a pilot, behind me, Manuferno. Further back follows Luroni, Lentomia, Faria and Ergonote.

There is also a weight balance problem and this is the arrangement, but due to the characteristics of the iron pile cannon falling from the head, now the rear-end ergonote will be at the top when the bullet arrives, and will first pop out.

"But that's narrow. It's good to have windows, but I'm gonna catch my breath."

"Air conditioning. For once, air circulation and purification are carried out by magical force."

"I see you don't have to worry about suffocating."

Looks like Manuferno is sensing signs of magic in the iron pile, but he's generally right.

"Haha, Izayuka, to the Demon King's Castle......!

"Come on, fly! Guess you'll entertain me more than my tank!?

The two avant-gardes who maintained strange tension are confused. The magical effect of Manuferno, but, well, it's much better than being freaked out.

"Okay, so shut your mouth, I'm gonna bite your tongue!

Kamui Iron Hammer (Kamui Caliber) Unit 1! Prepare to eject......! Tell them all. The facility entered a firing position. I repeat, this facility has entered a firing position. '

I saw the army technicians who kept me working all night and the wizards evacuating through the small window.

And when it fired, it didn't come at all.

"Finally! Gugle."

"Oh! It sounds better to be eating your teeth off at first"

"Nervous. Just a little"

"Manu, give me my hand..."

"Smile. Yeah!

Reach out from the gap in the seat to the manuferno sitting behind you. A slightly colder fingertip grabbed my hand firmly.

- Transmitted from the command post! Sage Lord Grecas, the iron pile accelerator, we're up and running!

The inner wall of the injection device is provided with a circular annular metal structure. This is the magic trick to launch the Iron Pile Cannon, the Fluid Magic Accelerator.

It's about seeing objects as liquids, accelerating and ejecting them with magic, and something like a metal ring continues surprisingly to the ceiling for a merte placement.

- Twenty seconds to ejection! Fifteen seconds...!

The countdown of the launch coincided with an increase in the magic pressure inside the hangar, which changed the colour of the ambient air. The ionized air became fluid and enclosed the iron pile.

"I'll be ready too."

Stretch the magic thread (MagiWire) inside the fuselage to interact with the tactical information display (tactics). Encourage further enemy junctions (circles) and monitor the situation without neighborhoods.

Naturally check the biological reactions (vital) of the crew on board, all clear.

"To the Issue Station, this is Sage Grecas. No abnormalities in the fuselage, all green"

- Roger, Iron Pile Injection Device, Ten Seconds to Critical! Nine, eight...!

"Okay, no!

- Three, two, one, lift off! Iron Pile Injection!

Dogwo-on! and a severe shake occurs at the same time as the firing. And due to explosive accelerations that also hold your breath, your body enters the cushion of your seat. and

Forced to accelerate by iron pile cannons, the 'four-style bullet' was quickly shot out into a dark void at an alarming rate.

"Ugh...!

"Scream. Gotta"

"Ha ha!?

"Awesome!"

"Ho ho...! Don't work, this is!

"Hah, hah ahhh!?

In an instant, the streets of the Wang capital become smaller. As such, the fuselage rises.

Pushing through the clouds that cover the night sky to rise altitude at once.

Eventually reached an altitude of ten kilometres Merte and a moment of silence came as we moved on to the horizontal flight. It was an amazingly quiet, moonlight lit world.

A full moon of blue and white shining was rising in the hollow.

I can see the lights of the villages and towns where people live from the slices of clouds.

"Farewell, Metanostadt, King's Capital......!
