Jin was now racking his brains to fulfill the request he had received from the Shoro Emperor.
Yes, a <

"Brother Jin, didn't you say at that time that you could do it right away?"
Erza sharply interrupted.
"Yes, I did, but after thinking it over, there are too many functions I want to add.

"You want to add features?"
"Yes," he says, "I've been thinking about it a lot. ...... For example, the tempura the other day, after a while, even if it doesn't get cold, the oil seeps in and it loses its crispiness. ......"
This was easy to understand because Elsa remembered this too.

The crispiness of tempura batter is important when it is freshly fried, and it will be ruined if the oil seeps into the batter after a long time.
"Oh, yes, that's right.
"And since it's a gift for His Majesty, I thought we'd add a layer of sterilization wards to prevent food poisoning. ......"

Erza was a little taken aback by Jin's obsessive nature.

"So, I was wondering..."
"...... understand. I'll help you."
Although she was temporarily taken aback, the wards that Jin is trying to create have a wide range of applications and are certainly practical.

As Erza often handles foodstuffs, she thought it would be better to have it.
"Sterile warding is no problem, is that right?"

"Yes.
First of all, since I was going to participate in the event, I started by sorting out what needed to be done.
"And the heat retention, no problem?"

"Yes.
The dish should have been almost ready when I came up with the idea.

"That's what I'm thinking."
This made it easier for Elsa to think.
"As for the poison, I think it would be easy to find a specific poison."

But what about unknowns? It's hard to say.

It is relatively easy for the human body.
Simply put, we only need to detect and exclude substances that are not naturally contained in the human body.

However, in the case of cooking, it is not always possible to exclude all substances.
"Elements are fine. Lead and arsenic, as I was saying."

But copper, chromium, iron, etc. are necessary for the human body as minerals in small quantities.
However, many of them become harmful when the amount increases.
Taking chromium as an example, trivalent chromium is necessary for sugar metabolism, but hexavalent chromium is carcinogenic and harmful.

"......, I think that's fine, since detoxification is not the purpose of the wards. I mean, you can't confuse the means with the end.
Erza's words made Jin reflect.

"Yeah, that's right. I was getting greedy and getting lost in the process. Thank you, Elsa.
Jin's hesitation is gone, and he has come to terms with the fact that the detoxification function is just an << extra>.

"Then it's a question of the oil.
The request originally came from a female emperor who said that cold tempura did not taste good.
Tempura soaked with oil does not taste good either.

Jin wanted to tackle this problem.
"Oil stain is a physical change, and oxidation changes the taste, so it's a chemical change.

Both can be stopped by lowering the temperature to absolute zero.

"No."

That would take away from the purpose of keeping the temperature.
Let's think about how to stop the motion of atoms and molecules.

Elsa has a middle school level of scientific knowledge, so she is fully capable of considering such a problem.

"You can't do that."
Jin denied what Erza had said.
As an engineer, I didn't want to use the word "impossible," but it would be impossible to do overnight.

"In principle, I think it is because the free magic element (ether) that enters the gap between atoms inhibits the movement of magic atoms, but I wonder if ordinary atoms are also inhibited."

Thank you very much.
