Let me start by explaining to you how to use a triangular scarf.

I would say a triangle scarf, but the truth is it's not particularly different than just a cloth. This name came from folding this in half, triangulating it and using it. And most of the first aid can be done with this one, which is excellent.

"First of all, I think the wounds you all suffer are a lot of knife wounds or arrow wounds. And if you have a wound, blood will flow from it."

Naturally, I'll explain once and for all.

Injuries cause blood, which is normal. There is no such thing as someone who doesn't bleed.

But you can't even leave the blood running.

"To stop the bleeding, you have to stop the bleeding. The easiest way to stop the bleeding is called compression hemostasis. This is simply to hold down and compress where the blood flows. That way, if it's a shallow wound, the blood solidifies naturally and stops."

Give Natalia a signal and get her hands on it.

I'll hold the wound and show you, assuming you've been wounded on some of its arms.

"But you can't hold back all the time. So if you want to stop the bleeding, wash the wound first. And hit the clean cloth. And finally, wrap it around while holding it down with this triangular scarf."

Do the trick of watering from the bottle you had prepared and then hit the handkerchief.

And at the end of the day, if you wrap it around with a triangular scarf, it's done.

You don't have to hold still, and now you can stop the bleeding after a while.

"Well, try it in pairs"

"Mm... you do it"

"Yes, this kind of technology is above all else."

Somehow, the people in front look disgusted.

But it's still best to actually try. Let them do it patiently here.

"Now, ladies and gentlemen, do it in turn. I'll coach you every time I go around."

"Hmm..."

You seem convinced for one second, and I will give you all a successful arm.

There are wounds everywhere, I guess, because that's still all we've been fighting on the battlefield.

There's only one person left, so I'll leave that person to Master Wilhelm. Nevertheless, I teach Master Wilhelm once, so it's just the patient role.

You're all confused, but you're wrapped in a triangular scarf.

I will teach you how to wind more efficiently as I go around each, plus the difference between cleanliness and uncleanness. No matter how clean the water you wash, the triangle scarf may become infected from it.

And after your practice, we will continue further.

"Earlier I asked you all to do the forearm procedure. But wounds are not necessarily arms, nor knife wounds. Next, if you break your arm."

Rather, this might be the triangular scarf you all know about.

If you break your arm, you must not move it. So you go through a triangle towel from your shoulder and make it look like you're lifting one arm.

I'll use two triangular towels for this. One is to fix the bone with a concubine, the other is to hang the arm.

Lecture on how to treat Natalia as a patient.

If you break an arm, if you have a head wound, if you have a foot wound, etc., the situation can vary, but it is a triangular scarf that works with all of it.

He also mentioned how to use a triangle towel to create an easy stretcher.

I will take a lot of time to do it and so by the end of the way the triangle scarf is handled, more than two-thirds of my appointments have already passed.

"... and that's how to use a triangular scarf. Any questions?

"It goes with the lecture earlier."

., and it was Deputy Vector who raised his hand.

He looked very sincere during hygiene, but he listened properly to his first aid class. He doubled the number of people, and he also put it into serious practice. Apparently, you trusted me a little.

"Go ahead, Deputy Vector."

"Hmmm... I was on the agenda earlier when I was in hygiene... is it still important to wash the wound with water"

"Yes, if you don't wash the wound with water, you don't know what kind of disease you will have. Assuming you get slashed with a rusty sword or something and leave that wound alone, there is also a risk of tetanus"

"Oh my...!

Tetanus.

I've heard about it once, it's a very serious disease.

Neurotoxicity causes symptoms that make your whole body cramped, but the cause is still unknown. However, there is a theory that when something rusty or unclean is in the wound, it can easily develop.

Perhaps some people suffered tetanus in the battlefield. From Deputy Vector's surprise, I don't think so.

And if it's serious, it's almost useless if you get tetanus.

For this reason, it is important to wash the wound with water.

"Wash with clean water and you're hardly in danger of getting tetanus"

"Uhm...... I know that. I know... as I said earlier, water is precious."

"It's..."

You would certainly be right.

What humans need most is water. Without water, humans cannot live for three days.

And if you use such precious water to wash your wounds, you run out of what you drink. I can see that, too.

"Sometimes we have to fight for a few days with just one water bottle. It's not uncommon that you can't drink water all day. No... I'm not denying the content of the lecture. As for hygiene, I understand. However... there is an aversion to using water that way."

"Really..."

I'm in trouble.

But once and for all, there are measures for this.

Not really, I don't want to say...

"On top of that, I want to hear it. Is there any other way than to wash it with water?

"... it"

"No, I hope not..."

Yes, I do.

I do.

I'm just not ready for my heart.

"Oh, there is..."

"Wow! So if we use that method, we don't have to use water!

"Yes... yes"

Kah, and I can see your cheeks getting hot.

In advance, I also gave a lecture to Mr Wilhelm, who did not have such a question.

But if you teach it right, you can keep your wound clean, and you don't have to lose water.

Kohon, and I'll cough.

I'm ashamed, but I'll tell you.

"Well, uh... in that case, instead of water... that... give me this."

"Mm-hmm? Instead of water, what?

"Uh... give me a..."

"No, I can't hear you."

How can you be so embarrassed to have to say this again and again?

I know you don't mean any harm to Deputy Vector, but I resent you.

"On the wound..."

"On the wound?

"Oh, pee, please..."

Oh. Ugh.

I'm ashamed. How did you tell me this conversation, Dr. Miyagi?

Urine is about as close to clean water as it can be and is not a problem for drinking.

I hear that some of them act to neutralize itching and insect poison. Washing the wound will not cause any problems there.

But I'm just embarrassed to say that.

……

……

I wonder why.

The Knights were looking at me like that with a face that was kind of even smiling.
