The deus ex machina, , was flying westward.

The altitude is about 3000 meters. The speed of flight is about 200 kilometers per hour.

< and is about 480 km, so the flight takes about two and a half hours.

All of the invited guests had been on an airship before, and although they were not excited, they still seemed to be intrigued by the sight below them.

"It's nice to see the view from the sky, isn't it?

"It is indeed. We are about to reach the southernmost point of the Kingdom of Selroa.

Fionn Fias and Tomax Bartmann were discussing the view from the sky.

But..,

"Inside <> ...... great workmanship ...... haha ......"

Illumina Ratkin, Deputy Chief Superintendent and Marikka's apprentice, was observing <> with all the interest of a magecraftsman (magi craftsman).

"Watthess, this is the technical prowess of Master Machina, the twin of Master Jinn.

"Yes, it really is a great achievement."

"Elena-sama, we must work harder and harder too.

Elena and her friends seem to be enjoying this precious experience and learning opportunity.

Below us, the clouds drifted by and the land flew behind us, revealing a man-made island in a wide expanse of azure sea.

"Oh, is that it?"

Someone looked at the artificial island and muttered.

"Yes, that is <>.

Makina replies.

"It's my base. It is an artificial island made by piling up rocks and soil on a cylinder one kilometer in diameter.

"Wow, that's great. ......"

The island is smaller in area than the two-kilometer-diameter Avalon, but it's a marvel in another way, in that it's more natural.

"It was created about 400 years ago by the second generation of , Jin-dono, and the first generation of deus ex machina," he said.

"Hahaha ......, that's unimaginable technology."

Tomax Bartmann was truly amazed.

And then he added,

"We're getting a welcome back."

Makina's words made his eyes widen even more.

"It's called <>."

It is a slender airship, 20 meters long and 5 meters wide. There are 20 of them in the air.

<'s path.

"That's my air force, top speed is 300 kilometers an hour."

Well, that's ......

That's impressive.

Everyone, except Elena, was astonished when they heard these figures.

descends slowly.

"The mountain in the center is Mount Olympus. The difference in elevation from the plain is 180 meters.

In fact, the top of the plain, or artificial island, is about 30 meters above sea level, so in terms of elevation it is 210 meters above sea level.

That is also an artificial mountain, isn't it?

"Yes."

Tomax Bartmann asked, and Makina nodded.

"It took the first generation of Makina and the second generation, Jin Nido, the Magecraft Meister, years of work to build it."

"Ummm ......"

The others, with the exception of Elena, were still thinking about this feat.

"There is an airfield on the south side.

<.

Aristotle descends slowly through the comet and lands on the airfield.

The ramp is opened and Machina is the first to descend, waiting for the guests to follow.

"Welcome to our Arcadia!

There were 20 units of , the army, lined up in a row.

< were not surprised to see , but Wattes Shrezza and Edda Yima, who were accompanying Elena, were wide-eyed.

"The airfield here is metal, isn't it?"

Ilmina Ratkin says.

The surface of the airfield is 18-12 stainless steel, embossed to prevent slipping.

The outer plate that covers the entire body of the except here is 64 light silver (titanium alloy) on the outside and orichalcone (Magi beryllium copper) on the inside, sandwiched between a mesh of mithril silver, which I will not reveal.

"Yes. This is also a hangar.

Makina explained as she moved the guests in the golem car driven by <>.

"Is it a hangar?"

"Yes. Yes. Please take a look.

As soon as the golem vehicle carrying Makina's group left the airfield, , which had landed on the ground, once surfaced for about 50 meters.

The next moment, the airfield split in two.

"Oh, no!"

What is this?

The metal plate that had been the airfield split in two from the center and slid open from side to side.

Because of its enormous size, it took about five minutes to open a 300-meter square hole.

"This basement is the hangar and dock."

"......"

The human guests were speechless at the scale of what had been done.

Only one person, Elena, had been informed of the event in advance and maintained a poker face because she is an automata.

"Even <> doesn't have an underground dock of this scale."

Illumina Ratkin said in a voice that sounded as if she had been moved to tears.

"The <> is 100 meters long. We need a dock of this size."

"And even so, it's amazing ......, that's all I can say."

Once the hole had been opened and < and the 20 descending < aircraft were stored, the hole slowly closed again and the airfield returned to normal.

"If it was a temporary landing, we wouldn't have stowed them all away. This time, I showed you this as an introduction."

The golem car started to drive slowly. Ahead of it is the towering Mount Olympus.

A hole opened up at the foot of Mount Olympus.

"My base is in Mount Olympus.

Makina explained that the base was located inside the artificial Mount Olympus.

"It is a mountain made of rocks pasted on a skeleton.

The guests could not help but groan at this explanation.

"Ummm ......"

"I didn't know people could build something like this with human power. ......"

The golem car entered through an entrance at the foot of the mountain.

"It's so bright."

The ceiling of the passageway was illuminated by ethereal light emitters (ALs), and the light was sufficient.

The golem car stopped at the end of a huge circular hall.

"Please get off here."

Makina led the guests out of the car and into the elevator in the center of the hall.

This will take you to the control room.

The guests and Makina got into the circular elevator.

"Let's go."

The elevator took them to the top floor, which was the command center of <>.
