At 1:00 p.m., Jin, together with Eira, Kaechea, and Groma, heads for the , on the way.

On his way there, he met Manon, the secretary automata that Jin had given to Tomax Bartmann.

Naturally, Jin asks Manon how she is doing. He is concerned about how his creator is doing.

"Hey Manon, how are you doing?

"Yes, Jin-sama. Yes, Mr. Jin. I have an announcement to make at ......1.

What is it?

We've finished analyzing the information crystal that Makina-sama found the other day in the depths of the ruins.

Oh...

Makina-sama, Tomax-sama, Elena-sama and the others will return this evening. So after dinner, we will hold a debriefing of the analysis results at 7:00 p.m. Please join us.

It was an unexpected event.

The reason why it took so long to analyze the data was not only because of <>'s poor analysis ability, but also because he was not familiar with <>'s technology and knew little about data compression, formatting, encryption, and so on.

If you had done it, you could have done it in a few hundredths of the time, but that was not an option.

Since it was not an urgent matter, Jin had left it to .

"That would be fun."

With this thought, Jin arrived at the .

The original members of the seemed to be engaged in their normal duties.

In other words, they are examining the Golem.

Now that the development of the small Golem has been completed, they are thinking about further improvement and development.

Jin and his group rent a small conference room at the and continue where they left off in the morning.

"The problem with the pinhole method is that the farther you try to project the image, the bigger and thinner the image becomes.

Jin said.

This is not surprising since the light is diffused that much.

"That's why you said it can't be projected very far, right?"

"Yes. If you want to project the light farther, you should use a light locus.

"But that would not be able to draw a complex magic circle, would it?"

Eira points out, and Jin agrees.

Yes, <> is like drawing a picture with a laser beam, so if you try to draw a complicated magic circle, it will take a long time and as a result, the magic will not be activated.

It is difficult to put it into practical use with the current technology.

This is the reason why Jin did not recommend this method.

"If the image is too dark, we can make the light stronger, and if it is too big, we can work on the projection side.

Groma says.

"That's right, that's what it comes down to."

Jin agreed that this would be the best way to extend the current technology.

In order to reduce the magnification rate of the pinhole projector, the pinhole, which corresponds to the lens, should be separated from the original image to be projected.

Therefore, Jin and his team decided to build Prototype 2, which should have a focal length twice that of Prototype 1.

Gromma was in charge of the housing.

The light source was to be made by Jin, as powerful as possible and as heatless as possible.

Eira is in charge of the projection of the magic circle. The magic circle was designed to be a <> magic circle. The trigger setting is not set this time, because we do not check the activation of the magic circle.

The size and balance of each cachet are adjusted.

The second model was completed in 30 minutes, since I had already made it once.

"Okay, let's try it."

Jin activates the light source.

The chassis that Gromma had built shone brightly on the wall five meters away, like a powerful searchlight, with no light leaking in through the cracks.

Then, Eira inserted the she had created into it and .......

"Oh!

"It's a good projection!"

The magic circle was clearly projected on the wall.

"It's okay if it's 5 meters away.

"If we move this away little by little, ......, the back is a wall."

Gloma, who was supporting the enclosure, was backing up and hitting the wall.

"We should have rented the main conference room."

Jin said, and KaChea stood up.

"Let's just use it for a little while now."

And then she ran off at a trot.

"You have a lot of energy at times like this, don't you?"

Eira muttered in admiration.

"I'm kind of bothered by such negotiations. ......

"Well, I can understand that.

Jin somehow agreed with Eira.

"I borrowed it!

Katya came back saying, "I borrowed it.

"So, they want to see how it's going."

"Well, I guess so."

< also seem to be interested in the progress of the research and development that Jin and the others are making. They are technicians, after all.

The large conference room is approximately 12 meters square, which is perfect for testing.

"Well, we're trying to project a magic circle at a distance, and then activate the magic there.

For some reason, Katya explains to the assembled group.

"Since this is an experiment, I'm going to make the room a little darker.

Jin now says and turns off the light. The curtains are not closed, so it is not pitch-dark, but just a shade of light.

"It's like this."

Gloma Trey projected a magic circle from a distance of five meters.

"Whoa!

"This is interesting!"

So I'm working on projecting this as far away as possible.

And so I'm working on projecting this as far away as possible," he said as he moved backward.

Six meters.

Seven meters. The image is a little larger and the brightness seems to have decreased.

8 meters. The image has become much larger and the brightness has visibly decreased.

9 meters. The image is larger, but the image is darker and less discernible.

"Hmmm, let's try making it a little brighter.

Jin, who had created the light source, adjusted the projector. The image became much brighter.

"Oh!

"Gromma, you're making the light source work too hard, so please check it quickly.

"Yes, sir."

And Gromma moves back further.

Ten meters. He manages to discern an image.

< applauded.

"Thank you. ...... Okay, I think I'm going to be able to complete the 10 meter task.

Jin was also satisfied with the result.

(This kind of development with restrictions is also fun. ......)

(This kind of development with restrictions is fun, isn't it?

Jin thought again that this fun was the same in the past and still is today.
