At Horai Island.

The old man was classifying and summarizing what he had gained from this expedition. Jin is with him.

"Buckwheat."

I don't know what the old man was going to say, because Jin said it with a happy expression on his face.

Buckwheat prefers cooler climate.

Even though Horai Island is in the subtropical zone, the mid-slope of Mount Horai, which is 3,000 meters above sea level, met these conditions.

<<

This is to prevent continuous cropping damage and soil thinning.

>.

"Oh, yes."

Jin thinks that next year he would like to try growing some in the village of Kaina. First, he would have to increase the number of seeds.

< clan had given him were not many, and he only had enough to cultivate them first. Then we would eat them.

"Yes, I agree."

>.

"Have you found out the principle?"

"Oh, that's great. And?"

What does that mean?　...... I have an idea of what you're talking about, but go on."

<<

Actual magic uses mana as its energy source. If you convert mana into free magic element (ether), it means that you are working to decompose magic.

And since it converts the free magic element (ether) into a form that can be used by you, that is, into magic element (mana), it is truly killing two birds with one stone.

"That's amazing."

Once the principle is understood, it will be a great defense against magic. In other words, <.

"Okay. Please continue your research."

The unidentified metal. As a sample, a piece of it was sent to me when I cut down the door.

"Oh, I see. We have never seen this metal on Earth."

In this world, perhaps because free magic element (ether) is added as a nucleon, there are some substances that even Jin does not know.

Adriana Barbora Zetsi, the previous Magecraft Meister, knew most of them even if Jin did not, but there were still unknown substances.

"Perhaps there was an abundance of it on Hale, the planet where the ancestors of humans and demons lived."

Mechanical properties are similar to iron. But the melting point was unusually high. About 5,000 degrees Celsius. No wonder it was used for spaceships.

I can't think of many uses for it, though."

Yes.

< to create 3D stereoscopic images.

In this case, it is characterized by the ability to deceive not only the sense of sight, but also the sense of hearing, or rather the reflection of sound.

<<>.

"Please."

"Yes, I think so."

I got a lot of snow tiger pelts and rock hare pelts.

Both of them are almost pure white, and I'm sure the ladies would love them if I made them fur coats.

Erza would surely wear them well, Jin imagined.

Now, we did not have enough time to analyze the ancient artifacts corresponding to the photo machine and the clock that Zion had mentioned before the expedition.

I plan to take my time and look at them carefully during my next visit.

"So, the last thing we need is a transfer spell.

The transporter also needs to specify the coordinates of the destination precisely.

The point is that the transfer will fail if there is a solid object at the destination.

Experiments have shown that the transporter bounces back to the destination.

Since the material used in this case was a simple stone, we do not know what would happen in the case of a living organism.

The reason why it works with gases and fails with liquids and solids is still under study.

"Still, it is useful for emergency escape. Please try to put it to practical use."

"Yes, the material of the ground dragon, could it be used to disable or weaken the gravity bombs?"

>

"Maybe cover it with a sheet of scales or leather, or a container."

The idea was that if the effect was weakened, the damage would be lessened.

<<

And as a bonus, the results of the analysis of <>.

I was completely out of my depth on this one.

.

Even the old lord himself, Jin, who was the source of his knowledge, was not familiar with chemistry and pharmacology, so he could not analyze the unknown chemical substances.

Unfortunately, it could not be helped. We can only think of them as such chemicals.

* * * * * * * * * * * *

Jin took a rest after the check was completed.

All that remains is to report on the <>.

"I'm going to have lunch first."

Jin stepped out of the basement command center.

The late summer sun was shining down on Horai Island. Jin stood tall under the blue sky.

"Brother Jin."

"Jin!"

A voice called out from behind him, and when he turned around, what did he see?

"Oh!"

It was Erza and Saki in yukata.

"I like this outfit. It's cooler."

Saki looked cool in her yukata, which had a bamboo grass pattern on a navy blue background. Her obi is yellow.

"How about ......?"

Erza has a leopard print on a navy blue background. Her obi is orange.

"...... I made it."

She made it herself, based on one given to her by Jin.

"They both look great on you."

"I'm glad you like ......."

"Kuhuh, is it?"

Jin's simple compliment made both of them smile happily.

"...... cold barley today."

"Heh?"

Jin had given up on such Japanese-style noodles because he couldn't find soy sauce yet, but Erza's words made his eyes widen.

"...... Perid reader seems to have picked up something that looks like it from the miso and adjusted it.

Miso and soy sauce are like brothers. Jin once went to Takayama on a company trip after entering the workforce.

Takayama is famous for its "hoba miso" (bean paste made from leaves of magnolia trees). And the morning market.

At the morning market, miso made by each household was sold, and some of them tasted like soy sauce.

Jin preferred the soy-saucey tasting miso.

"I'm looking forward to it."

We went to the museum with the two men dressed in yukata.

There, a peridoleder was waiting for them, dressed in a Japanese-style maid's outfit, i.e., a kimono, a sash, and a maegake.

"It is still a prototype, but we have made a little prototype soy sauce, so I made some mentsuyu to try it out. The broth is niboshi (dried sardines).

"Oh, I'm looking forward to it."

Thin, pure white noodles served on a bamboo colander. It looks cool with a piece of ice on top.

"Bon appétit!"

The three of us sit down in the tatami room and begin to eat.

Erza and Saki have been practicing how to use chopsticks, but they are still struggling with the thin cold noodles.

"Yes, it's good!"

The taste is still not what Jin remembers, but it is good enough.

The wind chimes hanging from the eaves of the houses are chirping, and the late summer on Horaijima is peaceful.
