"Jin, it's done."
"Oh, here we go."
What Erza was making was what is known as a golem's eye. In other words, a light sensor.

"Add the Magi Formula to it," she said.
While Erza was making the light sensor, Jin was thinking of a magical control flow (magi sequence) that would use it to measure the temperature.

"Father, is this the correct enclosure?"
"Here we go."
And Reiko made a housing for them.

"Yes, that's just right. I'll fit it in like this ......," he said.
What Jin had made was a
It is about the size of a TV remote control.

Instead of an infrared LED, the tip of the device has a
This light sensor is pointed at a ceiling or a wall and first stores a reference temperature in the form of infrared radiation.
When the infrared radiation is measured at the same location over time, a red light is emitted if the temperature is high and a blue light is emitted if the temperature is low.

The reason why they must be in the same place is that the wavelength of the infrared light emitted changes depending on the color of the object.
First, Jin points the camera at the ceiling and presses a button to memorize the reference. This will record the wavelength of the infrared radiation emitted by the ceiling.

Next, using his engineering magic, he heats the ceiling and points the
"Yes, that's a success.
If we can apply this to the ceiling, we should be able to control the temperature quite precisely.

At this point, Erza asked a question.
"Brother Jin, I thought that the Keowan ruins that we visited before had air conditioning inside.
"Oh, I see."

Erza was not as familiar with the past technology as Jin was, so this question was natural.
"It didn't detect temperature," she said.
"Then how?"

Jin thought for a moment about how to explain this.
"Well, it is correct that <

Jin nodded.

"Yes, it is. Controlling the amount of heat in a given space is quite advanced. However, it is not easy to use, and it cannot be applied.
"I see. You can't change the temperature, and if the size changes, you have to re-set it."
"That's what I mean."

Another way to explain it is that the control method is to keep the energy of the air molecules in the room constant.
This method is not suitable for controlling the internal temperature of a space suit, which is irregularly shaped.
"I understand that it's not very efficient.

The old man tested it in space and found that it withstood vacuum, extreme heat, and extreme cold.
The same result was obtained with GSP, but the difference in physical strength gave the advantage to the ancient dragon leather.

The transparency of GSP is higher.

"Yes, I think so."
Glass also becomes white when it is crushed into powder. Jin recognizes that this is due to the diffuse reflection of light on the irregularly shaped surface.
The same is true of the fine threads of subterranean spiders. But when they are fused together to form a resin, the original transparency of the material is clearly revealed.

"Now we just need to find a material for the outer shell.
Jin was concerned about the distortion caused by thermal expansion when making such a large object.

"We should develop a new alloy. ......
First, let's think about strengthening the invar.
"It's the standard mithril-silver addition."

Strengthening by magic was popular in Horai Island, including the Magi adamantite.
The experiment started the next morning.
The first step was to start with 1 percent.

Since the experiment was conducted using engineering magic, the efficiency was very high, and the optimum solution was found in the morning.
The optimum solution is found in the morning. 62% iron, 32% nickel, 1.5% mithril silver, 4% cobalt, 0.5% manganese, 0.5% manganese, 0.5% manganese, 0.5% manganese, 0.5% manganese, manganese 0.5 percent.
It is non-magnetic and has a specific gravity of 8.24, slightly greater than that of ordinary steel.

Iron and nickel are both metals that are produced in large quantities in Horai Island, so it was also convenient from that point of view.
Jin nodded at the old man's suggestion.

"Yes, that is fine. As long as there are no major changes, we can always rework it.
This is the beauty of engineering magic. As long as we don't change the size or shape, we can change the internal structure without any problem.

Elsa was also listening to the conversation, but she could not say anything about the spaceship because she did not understand it even if she wanted to.
"But I understand your point of view. The less danger, the better. I don't think there is any need to spare materials for that purpose.
Elsa also thought that it was a bad idea to be so generous when it came to the spacecraft that would venture into the unknown world of outer space.

"......I guess so. ......"
The final size of the spaceship was decided to be 300 meters in diameter.
