On August 4, a magi-machine for underground exploration, <>, began its exploration of the Inado Mine.
The <> resembles a shield machine used for digging tunnels on modern Earth, and is cylindrical in shape, with a diameter of 2 meters and a length of 3 meters.
It can dig in two ways: by using the < tool or by using a chip made of hyperadamantite.
The excavated soil is discharged to the surface by a transporter.
With sonar and magi-detectors, they dig while searching for foreign objects in the ground. This is to avoid missing valuable deposits.
The holes they dig are covered with magic to prevent them from falling down.
It was inevitable that the digging speed would be slow as they searched for deposits.
All we know is that there was an unfamiliar magical tool when a gigantopod once crawled out of the ground.
Before we could confirm its use, the cave-in occurred and everything was buried.
While digging out some zinc ore, <>, the mole was going underground.
August 12, 50 meters underground. Some arsenopyrite (sulfide mineral of arsenic and iron) and pyrite were found.
August 21, 100 meters below ground. Mining of olivine.
September 1, 150 meters below ground. Pomegranite was found.
On September 9, 200 meters below ground. This is the depth where the gigantopod crawled out.
The mole dug more carefully.
"There's something in there."
<
"It is a broken magical tool. I think it was crushed by the falling rock."
Craftsman (Smith)3 carefully digs out the grimoire as instructed by the Master, changes the setting of the transporter, and sends it out.
He then digs further.
On September 10, the <> hit a hollow at about 220 meters below ground.
"What is this place?"
It seemed to be about a kilometer deep and more than 300 meters wide. From the floor to the ceiling, it was about 20 meters, making it a large cavern.
However, it was clearly man-made.
The walls, floor, and ceiling were all unnaturally flat.
Craftsman (Smith)3 reported to the old man. He replied that he should examine the space in detail, and artisans (smiths) 4 and 5 were sent to assist him.
The three craftsmen (smiths) split up to investigate.
"A mysterious magical tool was found.
A mysterious material was found.
"Mysterious material found."
One after another, new discoveries were made. And then there was a surprise discovery.
"There is a room that seems to be a processing facility.
The referred to here is a facility for processing, that is, burning or melting, the carcasses of living creatures.
"With a scale this large, they must have processed quite a large amount."
Craftsman (Smith)3 reported to the old man.
"Is this ......? Golem found. It does not move anymore.
After all, what we found in the underground cavern are four mysterious magic tools. Since they are of the same type, their purpose seems to be the same.
They are made of a mysterious material, an unknown creature, possibly taken from a magical beast. About 50 tons of it.
Mysterious material. Black powder in a crystal storage container. About 20 grams.
The broken golem was nothing special to see.
The mysterious magical tool is being analyzed on the spot.
The mysterious material and substance were sent to Horai Island after the craftsman (Smith) had done as much research and analysis as possible and confirmed that there was no danger.
When Jin received the black powder, his eyes widened.
Yes, it was the same spiritual catalyst that Jin had received from <<700672> a while ago.
"How did you get this? No. 700672 said that it would take 100,000,000 units of brains to extract from the creatures of this world. I thought 700672 said it would take 100,000,000 units of brains to extract from the creatures of this world.
At that moment, the craftsman (Smith) calls.
"How is that different from an ether converter?"
"What?"
In short, it seems to work by collecting free magical elements (ether) from the surrounding space and increasing the concentration of free magical elements (ether) within a specific area.
A little while ago, you might have wondered "why? But now Jin had an idea of its purpose.
"Could it be that it was created by the demon tribe ...... or even by the <>?"
The climate in the north is harsh and the free ether is scarce in the south. The solution is to stay warm in the north or gather free magical elements (ether) in the south.
The facilities are designed to collect and increase the concentration of free ether.
.
"I see.
I'll tell them to send that to you as well, Jin. Then the old man makes another great discovery.
>
The old man speculated that they might have farmed magical beasts in a place with high concentration of free ether and extracted and collected the from their brains.
Jin also had a vague sense of this and immediately agreed with it.
Then, after a long period of time, <> or its descendants might have disappeared, leaving only a golem that simply continued its work.
Jin agreed.
"In any case, I'm glad we have a little bit of <>. We may not need to use it anymore.
The agreement with the demon tribe had just been made the other day.
However, there is no doubt that for creators, securing materials is a very dream-expanding thing in terms of expanding future possibilities.
Please send me some samples of your mystery materials."
.
Jin then picked up the material that was sent to him. It is silver-gray, shiny, and light. The flat but irregular shape is presumably due to the fact that it is a biological material and that it has been flattened.
It was presumed that it was probably the shell of a magical beast from which <> was collected.
With the amount of 50 tons, it is difficult to imagine how many years and how many magical beasts were crushed to collect the <>, and it is also something that Jin could not imitate.
However, it would be the best memorial service for Jin to make the best use of the materials left there.
"Well, ...... it's an unknown material."
Jin decided to reserve the material, taking his time to think about its characteristics and uses.
<>, or perhaps it was affected by it, and the gigantopod was born>>.
The old man guessed. Jin thinks the same thing.
"There are no more gigantopods around here, are there?"
.
"Okay, let's leave the cavity survey to craftsmen (Smith) 4 and 5 and let the mole go a little further underground.
So, craftsman (Smith)3 sends the <> deeper underground.
Since there seems to be no need to be careful anymore, he increases the digging speed.
After digging 50 meters in one day, the had found natural gold, natural platinum, and iridosmin (an alloy of iridium and osmium).
Iridosmin is hard and hard to wear, so it is welded to the gold tip of high-end fountain pens, where it rubs against the paper.
"I don't have much use for it, but Saki and Toa might like it. ......"
Jin thought about this and stored it in the materials cabinet.
The mole continued digging deeper into the earth, and at around 500 meters below the surface, he came upon a relatively large vein of Magi Crystal.
It was milky white in color, and had all the attributes of an average magi crystal.
"With all this, the budget of Kaina Village will be safe for the next 500 years or so. ......"
It was Jin's technology and the materials of Horai Island that made this possible, and if we look at the cost-effectiveness, the benefit is not so great, but Jin will never understand that.
