"Old man, were you sure that was the right thing to do?"

Jin, who was watching the exchange between Marikka D and < on Horai Island, asked.

<>> is 100% trustworthy, the answer is no.

"Hmm?"

> to check on them. Unless those two are spies for Oeste 3.

"I see."

Jin agreed with the old man's explanation and decided to wait and see what would happen.

can be reached by a transfer magic circle.

and move to in an instant.

...... It's too quiet.

Too quiet.

The two are not speaking, but are communicating via a built-in communication device.

[...... There's some dust on the floor.

Mmm. This suggests that the room hasn't been cleaned in a hundred years or so.

Assuming the air-conditioning is in working order.

That's true.

The air in <<> is circulated through a filter, so it does not accumulate dust.

I assumed that the same is true here <>, based on the degree of dust accumulation.

Let's move on first.

That's the only way.

Normally, the room with the transfer magic circle would be filled with several golems, but the fact that they were not there, they thought, must mean that something unusual is going on.

Knowledge is useless, since the structures in the base are all different from 1 to 3.

But I thought this was a base specialized in production.

Yes. But it's too quiet for that.

That's for sure.

This land would have been suitable for mining as well.

But the fact that we can't even hear the sound of digging proves that something was going on, he said.

The purpose of this visit is to confirm this .

Let's go to the bottom first.

Oh, yes.

is the mining site, and .

So, the two of them went for the deeper part of the base.

I don't see any golems guarding .......

That's for sure. This is too crazy.

They continue down the corridor and find a fire escape that leads down to the base, where they confirm that the door is locked.

Locked fire escape?

...... The most likely explanation is an intrusion by a foreign enemy, but I didn't see anything that looked like it.

The mystery only deepens.

The two of them went down the fire escape cautiously.

...... Well, the light is still on.

Hmm. But most of them are ethereal luminaries.

No, look at that.

Hmm?

In the direction to which <> points ...... down the stairs, there is one light that is not an <>.

Is that a ......

Is it a warning light?

The warning light of <> is not a blinking red light or a rotating red light.

A bright orange light means it. At least at the base.

The fact that there is a warning light in the basement means that ......

Could it mean that something happened at the ...... mining site?

The first thing that comes to mind is a cave-in, or volcanic gases, but neither is very likely from the technology of <>.

In any case, we would not know for sure until we went a little further, so <><>The two bodies proceeded down the stairs to the end of the warning light.

......m, corrosive gas?

Hydrogen sulfide.

About 5 meters down the stairs from where the warning light was illuminated, a strange smell began to permeate the air.

< and have the ability to analyze the atmosphere, they know it is hydrogen sulfide.

Hydrogen sulfide is a volcanic gas, after all?

I don't think a mining golem would be rendered inoperable by that much gas.

No, mithril silver is not very resistant unless it is treated on the surface.

Mithril silver also reacts with sulfur to form silver sulfide, which is a poor conductor of electricity as well as magic.

But that won't stop the golem.

That's right.

Basically, the mining golem is airtight and watertight. They are not affected by gases or spring water.

The exterior is made of light silver and plated with corrosion-resistant plating. ......

Then there must be another reason why it stopped.

That's what we have to find out.

The two bodies then proceeded to carefully descend the staircase.

<> is in the lead, followed by <> with an opening of 3 meters. This way, even if something happens to <>, <> will have enough time to evacuate.

Down, down!

About 50 meters down from the floor where the transfer magic circle was set up.

(...... hydrogen sulfide is increasing...)

Mm-hmm. But I don't think this is the direct cause of the anomaly.

The concentration is not high enough to have an immediate effect on the human body.

But the fact that these gases are floating around without being purified is more problematic.

Is the air conditioning in the lower levels not working?

That's all I can think of.

But since there are no humans in the area anymore, a little bit of gas shouldn't be enough to stop the base from functioning.

There must be something more.

We have to find it.

Mmm.

The two more bodies descended the fire escape and reached the bottom level.

This is probably where they will find the brain of the controlling magician.

Hmm. The concentration of ...... gas is still acceptable.

Hydrogen sulfide, when very thin, smells like rotten ...... eggs.

It is heavier than air and soluble in water.

Covering your nose and mouth with a wet handkerchief can lessen the effect for a short time (the best thing is to stay away from it).

Aside from that, only <> was illuminated in the hierarchy where the <> is located.

[...... this wildness is ......]

Did something go wild?

The floor was covered with scratches on the walls, floor, and ceiling.

However, no debris of any kind could be found.

I thought there might have been a battle between golems.

If so, it means that they cleaned up the mess.

Instead of solving the mystery, it has deepened it.

The two bodies, observing their surroundings, finally arrived at the room where the "brain of the control magician" was supposed to be located.

Here, the two close the distance between them and investigate the door and its surroundings.

I think this is it.

I guess this is it.

<.

But the door is also damaged.

It's unlocked.

Hmm.

<> opens the door, and <> peeks inside, and screams in ...... surprise.

Oh, my God!

What's going on?

<>, take a look.

<> tells him to look inside the room, and <> looks inside too.

This is ......!

There was a scene that was hard to believe.
