< terminates the relay, having concluded that the site is incomplete.

The time at <> is 3:00 PM.

Of course, they had lunch and a break along the way, but those who were watching were exhausted.

"Thank you, everyone, for your hard work.

Zion, who was probably tired himself, took charge of the event as the chairman.

"It has been one of the most tumultuous in recent years, but at the same time it has been a meaningful one. I hereby declare the 1013rd session of the to be over.

There was a round of applause.

Jin, Arnold, Delfina, and his mother, Rorona, did not hesitate to applaud.

Thus ended the tumultuous 1013rd .

< has ended, but Machina and his team's investigation is not over yet.

Or rather, the real work begins now that the live broadcast has stopped.

"First, let's check the power source.

Makina said, trying to find out how they were going to drive the countless at the bottom.

"Yes. The location is already half a level down, isn't it?"

"I see."

For the sake of convenience, I say , but it is in fact one level down.

However, the distance between the levels is about half of the distance between the first and the third level, so I used the term "" for the sake of convenience.

The old man has already confirmed the way to get there with his <, so please follow the directions to the lower level.

"Oh!"

There was a drive unit with a link mechanism, a rarity in Ars.

"But ...... this place is also unfinished ......"

Although the < were installed, 90% of the drive units were not yet mounted.

Nevertheless, the eleven drive units installed are sufficient for the survey.

"Please record the key points. I'll report back to later."

Makina reminds <, the photographer.

"Hmmm......... the structural material is reinforced special steel, the same as the exterior."

Here Makina decided to carefully check the materials.

"<><><>...... this!"

"What is it, Makina-sama?"

"Ray, I found something interesting."

The original strength of this steel was about the same as that of ordinary steel, but the subsequent magical treatment has dramatically increased its strength.

"The gaps between the metal atoms are filled with mana and then treated with <."

This is the same engineering magic used to strengthen coins.

Perhaps Adriana must have developed its basis, Machina-guide guessed.

In reality, there was no < in the engineering magic passed down from Adriana to Jin.

Adriana used and for structural strengthening, and and for surface treatment.

And for anti-corrosion treatment, we have developed engineering magic specialized for each purpose.

Of course, these can be applied on top of each other.

However, the idea of filling the material with <> and then treating it with << inert (inert) >> is quite an impressive one.

"Special steel would be as durable as adamantite, so it was ...... a revolutionary engineering magic then, and it's still a revolutionary engineering magic now."

Makina felt that if Jin could improve it further, it could be a useful piece of magic.

* * * * * * * * * * *

Next, she looked into how to drive the <>.

"It looked like a link mechanism ......, which is a kind of leverage using <>."

The basic structure is a rod with a spherical central part that is inflated to form a support.

Since the support is spherical, the range of motion is limited, but the rod can move in any direction and can rotate 360 degrees.

At one end of the rod, a < type magical muscle is attached.

Of course, the real thing is a little more complicated, and has two spherical joints.

"If we had 100 of these, ...... we could move as fast as a person can walk, right?"

It seems to work to the extent that it can <.

However, Makina thought that the energy efficiency of the machine was so low that even if it had been completed, it probably would not have been able to move.

Therefore, it could be said that it was abandoned.

The biggest problem is that it is not a "big" machine.

"But the biggest mystery remains.

Squire Ray said.

"I know. You know why it was buried underground and why the heavy metal contamination around it is so low.

"Yes."

Yes. Couldn't it be that the reason it was buried was because it was abandoned?

Makina guessed that they buried it underground because there was a big possibility that the enemy would take it as material if they just left it on the ground.

After all, this is a part of the , which was the site of a fierce battle.

"As for the heavy metal pollution, I wonder if it was used in the construction of this ?"

Hexavalent chromium can be reduced to chromium metal.

Mercury can be collected to make amalgam and is useful for plating.

Cadmium can be used as a substitute for solder due to its low melting point.

Arsenic is stored for reuse as a poison.

Makina's hypothesis is that the decontamination was done with these purposes in mind.

.

On Horai Island, two ultra-high performance magic brains were communicating with each other via ultra-high speed communication using free magic element (ether) wave.

I have verified this hypothesis to some extent and compiled the information to report to Jin.
