It took less than 10 minutes to reach the mine in Trom that caused the collapse.

To prevent a second collapse, the lands a few hundred meters away.

Ernst II, LeGrey, the Minister of Magic and Technology, and the butler rush out as soon as the cabin door opens.

Jin, Elsa, Reiko, and the five follow.

"Oh, I knew they were digging the mine here toward the underground."

The mines are not dug into the mountains, but rather from the ground to the underground.

By the way, < and have quite different meanings in modern Japan.

A mine is a place of business that mines, selects, smelts, and supplies resources, while a deposit is a place where resources are concentrated and can be extracted profitably.

In other words, mine is an organizational or geographical name and ore deposit is an academic name.

Anyway, out of the five tunnels that were drilled into the mine, the two tunnels in front of the mine collapsed.

Workers are frantically clearing away rocks and earth, but they don't seem to be making much progress, since the tunnels keep collapsing as they are being cleared.

"Your Majesty, I'll let the <> do it. Please tell the workers to get out of the way.

"Okay. ...... Everyone, I am Emperor Ernst II. We have come to your rescue. The Magecraft Meister will now use his golem to dig them out. Everyone must evacuate!

Your Majesty!

<>......?

Surprised by this reality, the workers evacuate the tunnels.

Jin then gave instructions to the <> who had followed him.

"<> 12 and 13, dig up the tunnel in front of you, 14 and 15, dig up the tunnel beyond that. 11 is for support as needed."

Using engineering magic to temporarily attach the collapsed rock and prevent it from collapsing further, the <> dug up the tunnels.

"Oh!"

"Amazing!　That's the golem of the !"

12 and 13 first fix the entire rock in place with , and then 12 makes a hole in it. 13 carries the excavated rock and earth out of the hole. The process is repeated.

The speed is more than 5 meters per minute. But as the digging continues. The speed will slow down. Because the distance to be carried out is longer.

"All right, you guys, we'll get the dirt out of here!"

"Oh!"

But a man who looks like the site supervisor gives the order, and they take care of the earth and sand removal.

This would make the work much more efficient.

Fifteen minutes passed.

"We have a wounded man!"

<>13, >11, who had been standing by, rushed in and brought him to a safe area.

A blanket was laid there, and a healer examined him immediately.

"This is ......"

Both legs were broken and the head was bleeding.

"What should we do? ......"

The mine healer, a young and inexperienced woman, was standing there, unable to decide what to do.

"...... get out of my way."

Then came Elsa.

"<>...... brain is clear. No bleeding. The blood from the head is from a surface cut. The fracture in the chest is more dangerous.

One lung is almost collapsed and there seems to be a pool of blood," Elsa said.

"It's a good thing the broken rib is not lodged in the heart. We need to get the blood out of the rib cage first."

"......"

The healer woman was still motionless when Elsa spoke to her.

"Come on, come on."

Elsa slapped the healer lightly on the cheek.

"Ah..."

"You are a healer, aren't you?　Then do your duty.

"Yes, yes."

"Yes." "Good."

After confirming that the healer had been reactivated, Elsa turned to the patient again.

"Do you have a drain to remove the blood from the rib cage?"

"Which one, sir?"

"You don't have a ......."

The blood is still the same as the patient's body, so it cannot be by engineering magic.

Jin rushes in and hands Erza a rubber tube. The tube is spherically inflated in the middle and acts as a pump.

The shape of this tube is quite different from what is called a in modern medicine.

It is similar to a pump.

Since the documents left by < Shuki Tsetsi were old-fashioned, such devices were only available in the 1960's. However, the devices in our world are still in use.

However, there is magic in our world.

Engineering magic cannot work on living organisms, but with the use of such aids, it is possible to <> blood.

Elsa inserted the tip of the drainage device into the patient's trachea while checking the patient's condition with a <.

She then drains the blood from the lungs. If it was water, I could remove it by engineering magic<> because it was a foreign substance, but I was thinking .......

(After all, it would be better to clarify why engineering magic doesn't work on living organisms.)

(It's still better to clarify why engineering magic doesn't work on living bodies.

If the blood is drained from the lungs, the healing magic will work better.

"<>"

This healed the chest fracture and stopped the bleeding from the lung at the same time.

"The dangerous situation is over."

Elsa sighed with relief.

Then five injured people were brought to the hospital.

< have already reached more than 50 meters underground, and it seems that there are still more victims.

Triage.

Triage?

...... don't you know?

Triage is the prioritization of treatment based on the severity of the patient's condition.

It is inevitably needed in times of disaster when the number of patients greatly outnumbers the number of doctors.

Elsa had proposed ...... four hundred years ago to divide the patients into four levels: late, urgent, seriously injured, and slightly injured.

(...... did not get the message. Too bad).

Elsa is a bit depressed, but that's not the point now.

"......And the <> are dividing us up, to some extent."

In addition, there are no patients with at least minor ...... injuries and no emergencies.

The most common injuries were serious.

Elsa personally examined them, giving <> to the seriously injured and <> to those with more urgent needs.

"Now we have some time to spare."

At least there are no more critical patients.

You see a patient in critical condition?

Uh, yes.

<

But there are still patients coming in one after another.

"There are too many ......, we'll never make it in time."

When Elsa complained about this.

"Erza, don't worry. < as well.

said Jin's voice.

"Hmmm.... The patients won't wait for us at ......."

"I know. I'll have Hope help you.

Hope can also use engineering and healing magic at an intermediate level.

"I'd like Reiko to help too, but we're trying to save the other side first. I'm sorry."

Reiko, who is smaller than the others, is now leading the way into the tunnels, searching for survivors.

"No, of course not. ...... rescue them as best you can."

And after more than an hour of feverishly examining and treating the patient, he looks up and sees <

I look up to see the huge body of <> about to descend.

< is faster than any of the 's flying machines, and thus the Machina herself has brought the healing personnel on board.
