Reiko, Erza, and Saki were also present.
<<......Master (Mylord), you say that there are still mysteries hidden in the underground?

"Hmmm, I think it's a bit exaggerated ...... or too big."
Jin denies Erza's question with a difficult look.

"What do you mean by that, Jin?"
This time the question comes from Saki.
"It means that it would be more efficient if it were smaller, if you just want to investigate.

"Oh, I see, you mean like the size of the hole to dig?
"Yes. I think it could be smaller, as long as people don't go in there later.
The environment of the Inad mine is the reason why the mole was made that size.

Jin said that he wanted to keep the size appropriate for a mini craftsman (smith) or a little craftsman (smith).
"...... that way, the cost would not be so high."
Elsa agreed, and they immediately began to consider the possibility.

"The main purpose of this project is to investigate the underground of the former Leonard's Kingdom.
"Indeed, that monster is extraordinary, isn't it?"
Saki has also heard about it, and the dissolved fluid of giant ants is also used to evaluate the physical properties of materials.

Erza nodded.

"I was wondering if there might be something like that underground in the old Leonard's Kingdom. The northern part of that country borders the village of Kaina.
"Yes, that's true. I can understand why you are worried.
Saki understood his concern and agreed with him.

"And one more thing. I am also interested in the underground structure of this planet.
Jin glanced at Saki.
"I think the fact that Horai Island has grown larger than its predecessor is a sign of volcanic activity, but it is not erupting now, and there are no active volcanoes on the completed world map. I wonder if this star is so small that it has cooled down considerably to its core."

"Hmm? What do you mean, Jin?"
Saki didn't seem to understand. No wonder. Saki has only studied science up to the elementary school level in modern Japan.
(Can't we make a magic tool for Saki to use a higher level of knowledge transfer (trans-info)?

) Jin is even thinking about such a thing.
"Well, you know, planets are cool on the surface but hot inside. That's why volcanoes sometimes erupt and hot springs spring up.
"Hmmm..."

"So, this planet is small ...... compared to the one I was on, but it's small ......, so I thought maybe it's cooler inside."
Since Jin's geology is only at a junior high school level, his explanation is a bit vague, but I don't even know if it makes sense to compare this planet Arus, which is on another world, to Earth.
"In other words, what is underground? How are magi crystals made? What kind of resources are there? That's what we want to find out."

Saki seemed to like this explanation.
"I see! Jin, let's find out! Come on! Come on!"
Erza stopped Saki's rush of energy.

"Saki, calm down. I'm just trying to figure out what kind of magic tools we'll need for this.
Yes, you're right. I'm sorry.
So, Jin took the lead in finalizing the specifications.

"10 centimeters in diameter and 30 centimeters long."
Looks like a large tea canister.
"Powered by a micro-magic reactor (magi reactor)."

A micro-magic reactor made by a mini craftsman (Smith). No ordinary ...... or even a first-rate magecraftsman would be able to analyze it. Even if it were to fall into someone's hands, it would be impossible to apply it.
"Propulsion is provided by a force field generator."
It is the most efficient propulsion method.

We'll also attach a magic eye to send information our way.
This is not surprising, since the primary purpose of the project is to investigate.
"In order to prevent the device from falling into someone's hands and being analyzed for any misuse, it has a built-in transporter, a self-destruct mechanism, and, worst of all, a built-in self-destruct mechanism."

The transporter returns to the inside of the
And so the specifications are determined one after another.
"I want to put a golem equivalent to a mini craftsman (Smith) on board, so that it can deal with contingencies."

Saki objected to this.
"Hmmm, Jin, I don't know about that. If some unforeseen event occurs that cannot be dealt with even with the equipment we have so far decided on, can we manage it with a mini-craftsman (smith)?"
Jin also refutes the question.

"It can repair the equipment when it malfunctions. And he's fast and can use invisibility, so I don't think he'll get caught."
"Yeah, or maybe ......?"
We have to take that kind of risk, Jin added.

In the case of tunneling, a conveyor is needed to discharge the rock debris from the rock.
Even if we use a laser to vaporize the debris, the gas must be discharged.
Hmmm, what should we do?

Jin thought that if we dig mechanically, the vibration and the sound of the digging would be noticed.

"Let's use the transfer gun method, after all."
"...... Jin, how are you going to do that?"
Erza tilted her head and asked a question.

"Well, we're going to attach the same thing as a transfer gun to the tip of the rock and transfer the rock backward in the direction we are going.
The distance of the transfer is the length of the

Saki offered a simple explanation.
"Yes, that's right. Since the distance to be transferred is short, the amount of mana consumed is also small.
"You mean, it advances intermittently?

"That's what I mean. We can use the micro-magic reactor (magi reactor) to create and accumulate mana, transfer it, advance, and create and accumulate mana again. ......
