"Father, Mr. Arnold, it seems to be here.



 Looking down from the window, she saw a wasteland.

"Well, if there is a free etheric reaction underground in such an empty wilderness, then this must be our destination in all probability.

"So what do we do, Arnold?"

Can you tell me the depth of the ...... free-magic-element reaction?

Wait a minute. If you move around a little bit and take some measurements, you might be able to ...... Hope, move about a kilometer to the west."

Yes, ma'am.

 This will allow us to triangulate and determine the distance. Subtracting the altitude, we get the depth.

 Immediately after the move, Reiko reported to me.

"We are 120 meters below the surface. The distribution indicates that there are cavities.

"That's for sure."

 Actually, the old man has already confirmed it with his peepers. It is definitely an ancient facility.

"They probably used a transfer magic circle to get in and out, ...... but I don't think there's anything left above ground, do you?"

I'm sure.

"Then what do we do?"

"Then what are we going to do?" "We'll use the mini-mole for underground exploration."

A mini mole?

Well, look at this.

 It looks like it's on board the Hurricane, but in fact it's a mini mole that the old man sent from Horai Island via a transporter.

 The mini mole is a cylinder of 10cm in diameter and 30cm in length. It is powered by a micro-magic reactor. Propulsion is provided by a force field generator.

"Oh, this is amazing!

It's small, but is it safe?

"Oh!"

  is 5 centimeters tall. No wonder Arnold is surprised.



"How did you make it so small and work so well ......?"

"I made a work golem that was a quarter of the normal golem, then I made another quarter of the normal golem and ...... did the rest."

I see...160 centimeters, 40 centimeters, 10 centimeters..."

Five centimeters is not a quarter, it's a half.

But it's a good idea.



 Arnold praised Jin's idea.

 Jin would like to welcome Arnold into the sooner or later, so for now he is showing his creations in small pieces.



"The contents of your research will be displayed on the monitor over here."

"I like that."



 Actually, the images will be sent to the command center on Horai Island, but the old man will forward them to so it will be fine.

 Jin landed the < and set up the mini-mole.

"<>, please."

"Yes, master."

Now launch the mini-mole.

"That's pretty fast. How fast are you digging?"

"Well, it depends on the quality of the soil and rocks, so it's hard to say, but if the conditions are right, it can go 50 meters or more per hour.

"That's great, we can reach the underground facilities in a little over two hours.

Do you think the underground facility is still alive?

"No, I don't think so. No, I don't think so. The free-magic reaction doesn't seem too great, so it's probably just air conditioning or a maintenance golem at best.

"I see."

 Is it sealed in this place in the first place?

 The old man may be the only one who is watching with a , but Jin thinks that there is no danger, seeing as he has not said anything.

He thought that there was no danger.



 Then, he waited for 2 hours.

 During that time, Jin and his team had free time to move around, checking the topography of the area and the composition of the soil.



"This land also contains heavy metals.

Read at https://w w w . m t l r e a d e r.com





 Environmental pollution by heavy metals, mainly mercury, beryllium, nickel, chromium, lead, zinc, arsenic, cadmium, vanadium and manganese, is called <>.

 Jin confirmed by <> that the samples contained mainly arsenic and cadmium, lead and mercury in trace amounts.

"<>...... hmm."

 Jin tried some engineering magic and found that metallic lead was extracted.



Read at https://w w w . m t l r e a d e r.com


 However, it is only about one gram of lead extracted from one cubic meter of soil.



 The specific gravity of lead is about 11.4, so it appears to be a very small amount.

Read at https://w w w . m t l r e a d e r.com


 If one were to consider a lead mine, the amount of lead in the soil would never be profitable.

 Nevertheless, the soil containing lead metal and others is preventing vegetation from flourishing, creating a desolate wilderness.

"Well, if we build a special Magi machine to remove toxic substances from the soil up to 5 meters underground, ...... it would be quite a task."



 With the Magi machine that Jin makes, it would take 2 seconds to the toxic substances from 1 square meter of soil, 5 meters deep...... that is 5 cubic meters of soil. It would take about two seconds to extract the toxic substances from one square meter of soil, five meters deep or five cubic meters.

 The area of contamination west of this < is roughly 250 square kilometers.

 A single magi-machine would take nearly 16 years to build.

 In other words, making 16 machines would take 1 year, 32 machines would take half a year, and making 200 machines would take Less than one month if 200 machines are made.

 If the same machines are to be used to clean up the Bororon Wilderness, it would be necessary to have 20 times the number of machines in terms of area.

"This, too, will have to be done after we report it to the king.



 Jin thought that although he could do it on his own, he should report to the king and get instructions from him .......

"I wonder how they contaminated it?"

 Jin was also curious about this.



"I've only heard that they turned the metal into gas and scattered it in the air.

Read at https://w w w . m t l r e a d e r.com


"......That's pretty bad. ......"



 Jin was disgusted by this inhumane tactic, as he could imagine that the vaporized metal would be taken into the body through the lungs or skin and cause various disorders.

 Jin also imagines that the method of making it gaseous would be a magic like <> .......



"These actions are easy to disperse, but troublesome to retrieve, aren't they?"

 Jin wishes there was a magic like time reversal, but that is an impossible wish.

"I guess we'll just have to collect them steadily. ......"



 As the wilderness spread out before him, Jin could not help but think of the karma of mankind.
