The discussion on the possibility of using engineering magic on human beings was reaching its climax.

　If only there were some more opportunities .......

　Then Martha, Hannah's grandmother, arrived,

"It's time for lunch," she said.

　She said, "Lunch is ready.

She said, "Okay.

　If I said I didn't want it because I was concentrating now, I would have been dragged away with a noose around my neck, so we all stopped thinking and went to the cafeteria.

　In the cafeteria, everyone in Horai Island was present.

　The menu was, unusually, grilled rice balls. The savory aroma of the grilled soy sauce whetted his appetite.

"I like this kind of thing too.

　The only accompaniment was a simple oshinko (pickles). The tea was hojicha.

"Mmm, delicious."

The aroma is indescribable.

　The time spent relaxing like this passed in a flash,

"...... can I talk to you about something else?"

　Elsa said in front of everyone what she was considering.



"Well, then, can I use engineering magic on my body?　If we can find out, we can take a step forward.

　Jin said with a difficult look on his face as he folded his arms.

"...... Hey, does that mean it's okay for me and everyone else?"

"............ what?"

　Jin's body is made of , and everyone else is a homunculus.

"Ah."

　Erza realizes that Jin has just pointed this out,

"I ...... was careless."

　She was a little wistful.

"But if you need help, I can get Theon and Rhodes to help you.

"Yes, I'd like that very much."

"Okay."

　So Jin asked the old man to contact Rhodes, and Rhodes, who was available, agreed to help.

"Hello, everyone.

"It's been a while!　Not so much ......."

　And Ludmilla came with him.

　Sion had to go to work and unfortunately could not come to the meeting.



"That's why ......."

"I see, so that's how it is. Can you use engineering magic on yourself?"

　In addition to Jin's explanation, Erza also gave a supplementary explanation.

"If you can use engineering magic on a living body, it will be useful for treatment. I would like you to cooperate with us.

"Okay. What should I do?

"Try to deform the tip of the nail with the engineering magic, forming.

"I will try. I can do it with ......<>......."

"Oh!"

　This was a new discovery.

　If we can <>, we may be able to restore crooked bones with engineering magic.

　At the moment, for such diseases, the bones are broken once and then healed again.



"So, can you use <> to cut an elongated nail?"

"I will try. ......<>...... done."

"Excellent."

"Well, can you apply < to some of the hair?"

"Well, I don't want my hair to look like needles, can I use hair from my arm?"

"Sure, sure."

　Rhodes said that he would still like to use the visual method to target specific hairs.

"Well, then. ......<>...... you've done it."

　One of the hairs on the back of his hand was as hard as a needle.

　I tried to pull the hair out with a plucking tool, but it really looked like a needle.



　So far, this confirms my hypothesis that engineering magic works on my body.

　Whether this is conditional or not, or whether all engineering magic can be used ......, remains to be seen.

　As for Elsa, she would like to use <> to treat internal bleeding or to replace drains as she did the other day.

　As I could not ask Rhodes to do that, I decided to end the human experiment for the time being.

"Thank you, Rhodes.

"No, I'm glad I could be of help. ...... and, from what I understand, to improve your medical skills, right?"

Yes. Yes, and thanks to you we have made a step forward.

　Thus, it was proven that I could use engineering magic on my own body.

　This is only for the time being, because we have only been able to confirm that the magic has a physical effect.

I would like to try chemical engineering magic if I can."

　<> to dissolve stones, <> to cure carbon monoxide poisoning, and so on.

"I suppose it could also break down melanin pigments and remove blemishes."

"Indeed."

"And if we can break down cells into carbon, oxygen, hydrogen, and so on, we can get rid of tumors."

Yes, that's true.

　The fusion of healing magic and engineering magic has only just begun.

"Well, that was interesting.

　Saki, who was watching Elsa and Rhodes' experiment, said happily.

　The whole Jin family was watching with bated breath.

"Well, that's a big step forward," said Saki. And the mystery is how engineering magic works on living plants?

　Erza nodded.

"Saki is right. We still haven't explained why engineering magic doesn't work on a living tree, but it does on a branch broken off from it."

　At that moment, Licia asked a question.

"Well, I was thinking in terms of <>, can you > with living plants?"

　Elsa answered,

"I'm not sure if they can or not. After all, they are <."

"That's right. ......"

　Since there is no clear consciousness or <>, we don't know whether the magic pattern itself exists or not.

　Therefore, even if they want to , they can't do so.

"So, biological materials cannot be processed in the same way as metals in the first place?　It's not ......, is it? and can be processed, can't they?"

"That's true."

　At this point, Jin speaks up.

"Even wood can be used for engineering magic such as <> and <>. This is fundamentally different from <> or <>, isn't it?

"That's certainly true. ......"

　Jin added,

"With <> you can cut a standing tree. If it were done on a very small scale, it could be <>. ......

　He said.

"That's an interesting idea, girl."

　Hannah also seemed to be interested.

　Everyone present felt that it was a good idea to share wisdom and pursue a question in this way.
