"Camera or ......"

After leaving the 700672, Jin rushed back to the lab.

"Brother Jin, you look happy."

Elsa said, seeing Jin's lively face.

"Yeah, I just couldn't make photographic paper. I wonder how this works. Let's try ...... first."

Jin pointed the camera at Elsa and pressed a button.

"What?"

Erza's face was filled with surprise.

Then he pulled out a piece of photographic paper from inside the camera, and there was a picture of Erza.

"Oh, it's there, it's there!"

The operation seems to be similar to that of an instant camera.

"Here's ........."

The image quality is quite good. As expected, it is a gift from No. 700672.

"Let me see ......."

Erza snatches the from Jin's hand as if snatching it halfway. Her face turns red.

There is a startled look on Erza's face when the camera is suddenly pointed at her.

"...... tease."

Erza's face swells up.

"Sorry, sorry. But Erza with a natural face like this is cute, too. No matter how she looks, Erza is still Erza.

"...... already."

I can't be mad at you if you talk like that," Elsa grumbled and put the photo back in her pocket.

"Oh, wait a minute. I haven't checked it yet."

Jin rushed to retrieve the photo.

"...... no."

But Elsa held his pockets and refused to give him the photo.

Reiko, who could not bear to watch them arguing, gave them some advice.

"Father, why don't you take another picture?

"...... Oh, I see..."

"If it is all right with me, please take as many pictures as you like."

Elsa stepped forward as if to intercept Reiko, who was puffing out her chest.

"...... copy me."

Behind Erza, Reiko was smiling a pleased smile, but neither Jin nor Erza noticed the expression on her face.

Jin takes another picture of Erza with a composed face, and applies to the picture in his hand.

Her face was colored with surprise.

"This is ...... that way!

But surprise is replaced by frustration.

"Brother Jin?

"Father?"

The two look worried,

"...... No, this dye was the same kind as . ......Oh, I wonder why I didn't think of that!"

Magical dyes change their color from red, orange, yellow, green, blue, indigo, violet, and red-violet depending on the amount of magic power applied to them.

Jin guessed that the color of the material used here can be changed to a more intense one.

"The wavelength of light is converted into magical power to produce the color. I think they also change the intensity of the light by converting its intensity into magic power. I thought of that very well, didn't I?"

Jin explained in a tone that still had a hint of regret in it.

"I'll have to look into it more closely to make the same thing, but the principle is as I just said."

In principle, there is no <> involved. It is exactly like an .

If we can take <>, it will be convenient in many ways to keep records. Yes, even data on <>.

Jin has decided to study this method and try to reproduce and mass-produce it.

* * * * * *

"Well, the point is that the color changes with the wavelength of magic power and the density changes with the intensity of magic power. ......"

We were able to identify the characteristics of magical dyes, but we had no idea of the key magical dyes.

The existing magic dyes change from red to red-purple, but the magic dyes used for photographic paper seem to have coloring characteristics similar to the spectrum of light.

"Brother Jin, is this also a biological material?"

"Hmm, that is a strong possibility.

It is hard to imagine a material found in nature having such characteristics.

"Then it must be Mr. Goose."

Edgar spoke up, which was unusual.

"Well, let's go to ...... and ask him. Saki seems to like this kind of research."

So Jin took Reiko and moved to Saki's house.

* * * *

"I'm going!　I'm coming!"

Sure enough, Saki bites.

And Goose?

"...... hmmm...... maybe it's an <>...... or maybe it's a <> (rayoti worm)>>?"

"You know, Goose?"

"Yes. The pigment Jin is talking about could possibly come from the rainbow worm.

According to Goose, the rainbow worm is the larva of the rainbow butterfly, an insect that lives deep in the mountains of Huso.

"The larva changes color depending on the type of magic it possesses. The adult is a beautiful butterfly with a tail as thin as a string.

"Oh, ....... Does the butterfly change color too?

"No. When they are larvae,...... or rather, just before they turn into pupa, their wings are the same color. It is only when they are larvae that they change color.

"I see."

"I see." "There must have been villages that used them as a dye."

That was good news.

"Can you share it with us?"

Yes, ....... It's not so rare, so a small amount would be fine, right?

"I see."

Then, since we can't overfish, Jin wants to think about aquaculture.

"Anyway, I'll go and ask them to share it with us."

Jin said and left the room.

Goose stops him.

"Of course I'll go with you.

Jin nodded silently.

"I'll go with you, then."

Saki came forward.

"Okay. Then let's go to Horai Island and take the Conlon 3.

So the three of them moved to Horai Island.

"I'll go with you.

Naturally, Erza followed them.

In the end, with Edgar as pilot and Reiko as escort, Jin, Erza, Goose, and Saki took off for Fusor in the <>.

On the way, Jin gave Goose and Saki a detailed explanation about the <>.
