Magicraft Meister Part 4

The northerners, who are more powerful than the humans on the Laurentian continent, were able to remove the earth and stones in a short time.

There was a tunnel entrance covered with a rusty iron plate.

Naturally, the group tried to remove the lid.

"Oh, this is the entrance to the old mine after all.

"I'd like to check inside, but I'd probably ...... run out of oxygen. ...... Momoko, can you help?"

Naturally this is where Momoko comes in.

"Yes, I'll take care of it."

Since the area has been closed for a long time, it is unlikely that dangerous creatures are here.

Instead, it is more likely to be filled with flammable gases or gases that are harmful to the human body.

Momoko therefore turns on the magic light and begins to investigate the old mine.

<

Infrared light alone would have missed some details.

>.

Momoko reports using the manaphone on her backpack instead of the built-in manacam.

"I see. Be careful on your way."

.

Momoko then proceeds cautiously.

The tunnel is so solid that it is hard to believe that it is more than 700 years old.

<

It is a proof that the workers of that time did not cut corners and did a solid job.

Momoko slowly descends down the tunnel, which extends diagonally downward.

Momoko reported.

"Has it been denatured by geothermal heat?"

<

"Go carefully."

.

is a unique mineral that is formed when limestone reacts with magma, and is an aggregate of < minerals, mainly composed of calcium and silicon.

On the earth, < are such minerals.

And here on Ars: .......

<<>.

It seems that magi crystals have been mined.

"What are its size and properties?"

<

"Good. A little further."

Momoko continues to go deeper.

The next thing she finds is .......

"I see. Collect them and continue on your way."

<

Pyrite is a compound of sulfur and iron, phlogopite is a compound of sulfur and lead, sphalerite is a compound of sulfur and zinc, and pyrite is a compound of sulfur and copper.

All of them can be found in skarn deposits.

"It looks like it must have been a former mine site," Rhodes said.

Rhodes says, and the engineer, Archista of the , agrees.

"What about the air composition?"

"I see."

Methane and ethane are both combustible gases. However, if there is no oxygen, there is almost no danger of ignition.

The tunnel, which had been a straight road up to this point, was now divided into three separate tunnels.

The tunnel was about the size of a four-and-a-half-mat room, and there were three destinations.

One straight, one diagonally to the right, and one diagonally to the left.

Since all three tunnels were almost the same, Momoko asked Rhodes to make a decision.

"Well, try going straight ahead."

.

With Momoko's memory and spatial grasp, there was no way she could get lost in an abandoned mine of this size.

Following Rhodes' directions, Momoko took the middle path.

The gently descending path became almost level after about 30 meters. And there was still more to come.

This time, the path went uphill a little, but Momoko kept going.

She had probably walked about two kilometers by now, but the tunnel was still continuing.

But even the longest tunnel has an end.

The end of a gradual ascent.

There was a rusty iron lid.

"Yes, how does it look?"

"What?

Not all tunnels have a single exit, and this one was connected to another one.

"Can you open it easily from the inside?"

Momoko released her suppressed power and pushed the iron lid as hard as she could.

A rattling sound came from outside.

As she continued to apply force, the lid began to shift little by little. At the same time, the response became lighter and lighter.

Finally, the iron lid collapsed, and sunlight began to shine into the tunnel.

.

"Thank you. I heard the noise from here too. Stay there for now."

<

Momoko waited, and in about three minutes Kondak and Zeddis from Shinra arrived.

"Oh, there's another way in and out of here."

"Kondak, should we put up the bars for now?"

"Yes, let's do it quickly."

The two had come here to prevent the place from becoming a nest for wild animals and magical beasts.

They transformed the iron lids into iron grates with engineering magic and reattached them.

Kondak is Marikka's grandson, so he is good at this kind of work, and Zeddis is also an engineer who participated in the held in Toka Village before.

The two of them worked quickly, and in about five minutes they had installed a sturdy iron grate into the doorway.

It was a rock building, almost the same shape as the one where Rhodes and his team were located.

"That's it. If we do this right, we may be able to change the air in the tunnel.

"Momoko-san, we will now return. You can go back to the branch too.

"Yes, sir."

Kondak and Zeddis went back the way they had come.

Momoko also went back along the tunnel.

They arrived at the small hall where the branch was located. She immediately contacts Rhodes using the built-in manacam.

>

"Well, then, from our side, try to go to the right.

<>

Momoko now proceeded to the tunnel on the right.

At first it was a gentle descent, but the slope gradually became steeper and steeper, until it reached a steep slope of about 30 degrees.

The ground was quite rough and uneven, so we did not slip.

When we were about 100 meters below the surface, the slope finally became more gradual.

Then a rusty steel door appeared.
