Magi Craft Meister

An underground city that should be in the 'continent of Rachel'.

Old man is searching for clues using all the means he can pick.

It's all over the ground now, and I'm just looking for clues like vents and entrances and exits.

For this reason, observe the ground with the observing satellite 'Watcher' from the satellite orbit.

And he scans the northeastern part of the continent without a scratch.

I had some hands on sending Rand squads, but the area I was looking for was huge, so I dispersed them even with the modest Rand squads, and the decision was inefficient and I haven't put them in yet.

As soon as we find clues, we plan to put in intensive input.

"Yes."

Jen, who was having dinner with Elsa on Penglai, suddenly raised her voice.

"Brother Jin, what's wrong? Did it taste bad?

Elsa leans her neck and asks, but Jen denies it.

"No, I'm not. I've come up with one thing................ yeah, I think I can"

To Jen like that, Elsa asks.

"What kind of thing?

"I'll explain now.... Uh, now you're looking for an underground city in 'La Seal Continent', aren't you?

"Mmm."

"I'm investigating the ground, but I haven't made much progress"

"Yeah."

"So, if we're going to explore the underground, we're going to explore the underground."

"Ah."

"But if you use 'Underground Exploration' for Darkless Arrow Cod, you must not have any negative effects, and the old man seals it."

"'Elder'... not, 'Tarless' said that too"

"Yeah. That's why you change the way you do it."

"What do you mean?

"That's..."

Jen starts explaining to Elsa.

Said, "Underground Exploration (Grand Search)" has prioritized "Depth" to date.

Said, "depth" shall be changed to "spread" and "underground exploration (grand search)" shall be used.

That way, we thought we might be able to detect changes in formation, rock formations, etc. … artificial processing marks…

It is a great way for his land covered in dense woods and difficult to search visually...... should be.

"Brother Jin, wow"

"Ha, thanks. But, well, it hasn't been successful yet."

"That's right."

"... Well"

"Brother Jin, stop"

Jen with her hips floating, Elsa grabs her sleeve and stops pushing.

"Elsa?"

"... starting tomorrow"

"Oh, yes."

They sensed Jen was about to go to the workshop.

That kind of thing starts tomorrow, and Jen gets stabbed in the nail and sits back bitterly laughing.

"Tonight, without water"

"... right"

The evening on Penglai went quietly further.

And the next morning on the 21st.

Jen, who had finished breakfast, was caged in the workshop.

Using Reiko as his assistant, he wants to create an Underground Explorer (Grand Search).

"If we rewrite the parameters of Magi Formula here, we can explore the breadth as a priority, not the depth."

"Father, do you make it variable?

"That would be better. Get me some light silver."

"Yes."

The prototype is complete in roughly half an hour.

"Okay, let's try it"

It's just a matter of looking into the ground, so it's not dangerous enough to say at all.

It's a prototype, so ask Reiko to hold that about the size of the Minkan box, and Jen will try it in the front yard of the lab.

At the bottom of the box is a transmitter that emits the magic wave of Underground Exploration (Grand Search) and a receiver that receives the magic wave that is reflected back in the ground.

And on the top, there is a monitor for the Magic Screen application, which displays the scan results.

The majority of them, which have grown, are data banks for ground information, computational apparatuses for comparison, and interfaces for display.

In the field of information processing, modern Earth still seems to be a little ahead of magic engineering, Jen thought.

I really don't like 'IC (Integrated Circuit)' technology.

However, as for Jen, it is possible to process micrometer and nanometer orders using a mini "craftsman (smith)" system.

Besides, this prototype was generally a success.

It was variable from 1 to 10 meters underground, and it covered 10 to 100 square meters.

"All right, all right, then why don't we make the variable range a little wider"

Jen starts messing with the prototype on the spot.

In this respect, armaments rise to magic engineering over Earth science.

Re-use or rework is easy.

"That's it."

Test again.

"Yeah, this would be nice"

Depth varies from 0 to 100 metres and the breadth covers from 10 square metres to 1 square kilometre.

"Looks like you should build a new one for any further range expansion. Reiko, we're going back."

"Yes, Father."

Returning to the workshop, Jen created the next prototype based on the items that could be confirmed in the prototype. In other words, it is a 'mass production prototype'.

Now it's done in fifteen minutes.

The size also decreases to about A5 size comics. Most importantly, smaller than this would make it difficult to see the monitor.

Tested again in the lab's front yard.

Naturally, the contents of the investigation will be the same as earlier. but its performance is different digits.

"Depth ranges from 0 to 1000 meters and breadth from 100 square centimeters (10 cm square) to 100 square kilometers (10 km square)...... yeah, that's enough"

The measurement takes 20 seconds. This one was fast enough.

"Okay, let's mass-produce this and let 'Rand Squad' take it and find out"

Jen also helped the Craftsmen to produce 100 of these Underground Explorers.

We decided to let the 'Land Squad' have it and send it to the northeast of the 'La Seal Continent'.

"That's what I'm asking you, old man."

"Yes, Master (My Lord), I'll take care of it"

The third stage of the Northeast Survey of the "Rachel Continent", led by the old gentleman with whom Jen enjoys tremendous trust, is launched.
