The next day, January 26, Jin and Elsa finished breakfast and were discussing their plans for the day.

Just then, there was a knock at Jin and Elsa's door.

"Come in."

Reiko opens the door, and there he is.

"...... brother?"

It was Elsa's brother, Fritz Randall.

Fritz bowed to Elsa with a somewhat embarrassed look on his face.

"Erza, it's been a while. ...... and I'm sorry about the other day. I'm sorry."

"...... head up. I don't hold grudges anymore."

At the sound of Erza's voice, Fritz raised his head and then turned to Jin.

"Jin-dono, no, Sir Jin Nido, I have been rude to you in many ways. I would like to apologize."

He then bowed his head. Jin panicked.

"Please raise your head. If Erza doesn't mind, I don't mind.

At this, Fritz finally lifted his head.

Then he turned to Erza again,

"Erza, I don't know how I can ask you to do this, but ......"

He looked uncomfortable to say this. Elsa tilted her head, which was unusual for her brother.

"Brother, is something wrong?"

"......Mr. Gloria, a female knight of the Klein Kingdom, has been seriously injured. She's not healing well. Would you please take a look at her?"

Then he quickly adds.

"...... her face and right shoulder have been burned by the liquid of the demon's vomit.

"...... yes."

Jin and Erza had heard the report from the old man, but they could not help but be shocked to hear it again from Fritz's mouth.

"...... I understand. Gloria is no stranger to you. If it's a favor from my brother, I'll do it."

"Oh, thank you!"

Fritz took Elsa's hand and bowed repeatedly.

Then he said,

"Well, I'm going back. I'm going to go back to Cynthia, my second in command, and ask her when she would be available.

He left the room with these words.

"...... was a careless thing to do, wasn't it?"

Jin muttered in a whisper.

"We didn't keep track of them after they were transported by hot air balloon. We prioritized the mess at the ruins."

"That can't be helped. It's not Jin's fault. Even the old man didn't follow the trail any further.

Elsa followed up.

"You don't have to take all the responsibility. ...... I'll take care of it. Don't worry."

"Yes, thank you."

While we were having this conversation, the door was roughly opened.

"Elsa!　I can do it now. Please!"

"...... brother, knock, please."

"Oh, oh, I'm sorry. Come to ......!

Jin bro, I'm coming.

"Yeah, be sure."

Elsa and Fritz headed for the healing wing.

Cynthia was waiting for them in front of Gloria's room.

"We've been waiting for you. "Thank you, Miss Elsa," Cynthia said.

"...... will do our best."

I'll be outside."

Fritz said he would not go inside, but would wait outside for the healing process to finish.

"Excuse me."

Elsa entered the room with Cynthia. Gloria was lying there in a very disfigured state.

"...... Miss Elsa."

"Ms. Gloria."

After a brief exchange of greetings, in which they simply called each other by name, Erza immediately began her examination.

"<>"

Elsa continues to examine the patient several times. Cynthia looks worried.

"...... How do you feel, Erza-sama?"

"Ordinary healing magic can't do it."

Hearing these words, Cynthia's shoulders slumped.

"I see,...... then, Gloria-sama has already,......."

But Erza shook her head.

"Normal," he said. There is one way to fix this.

Well, what's that?

It's a little cruel.

The reason you can't heal an old wound with healing magic is that it is fixed in place.

To overcome this, we can remove the old wound, prevent secondary infection, and cast a higher level of healing magic.

<, the patient will not be in pain.

But there is one problem.

Elsa has no experience in such a surgery.

(What should I do? ......)

The risks make me nervous.

(How to prevent bleeding and secondary infections......)

Elsa thinks desperately.

(Low temperature?　...... yes, that's it then).

The point is to remove the abnormal tissue from the affected area without risk.

Elsa has come up with a method to restore the normal tissue by freezing the affected part to necrosis and then applying healing to it.

On the modern Earth, the same kind of treatment is used for fish eyes using liquid nitrogen.

On the other hand, on the modern Earth, there is a method to treat keloids of burn scars by repeated laser irradiation, but Erza is not capable of such precise irradiation.

On the other hand, since ELZA is capable of ultra-fast healing, which is impossible with modern medicine, it seems appropriate in this case.

The only problem is that...

(...... there is no guarantee whether it will work or not)

Yes, this is the first surgical treatment method for Elsa as well.

（If only my brother Jin were here.)

I don't think so.

"...... Erza-dono?"

Gloria called out to Erza, who was lost in thought.

"......After all, my wounds are not healed?"

"...... No. I think it can be healed. I think it can. It's just that it's the first time I've tried it and I'm not sure.

Elsa confided honestly.

"I believe in you, Erza-sama, who has cured our country's Majesty so well. I don't think it will make much difference anyway, even if it gets worse.

Gloria smiles somewhat self-deprecatingly, and seeing this, Elsa makes up her mind.

"I'll do it. Please leave it to me."

"I'll do it."

"<>"

First, Elsa paralyzes Gloria.

Sterilization.

Next, the entire affected area is sterilized. Up close, the keloids are quite severe.

<>"

The engineering magic cooling is used. It is a magic that lowers the temperature of an object. It can lower the temperature of an object to minus 80 degrees Celsius, below the temperature of dry ice. It is also a water magic, so it works on living creatures as well.

"......<"

Intermediate level of surgical healing magic. This causes the skin that has been necrotic at low temperatures to peel off in pieces, and the skin, including the epidermis, dermis, and subcutaneous tissue, is regenerated.

"...... worked."

The first step was to apply the procedure to the right shoulder, which was the most severely burned area, and the skin regenerated without any problems.

"That's ......!"

Gaining confidence, Elsa proceeded to treat the neck, face, and right chest.

"That's great ......."

Cynthia, who is watching from a little distance, lets out a word of admiration.

"<>"

The treatment was completed with a high level of medical treatment to regulate the circulatory system in the body.
