"Oh yeah, a barrier!"
After half an hour of thinking, Jin finally looked up.

Then he drank the tea that was in front of him.
"Hmm?"
The tea was still hot enough to drink.

He looked in front of him and saw Erza smiling at him. That's when Jin realized.
"Erza, did you put
Erza did not answer, but only smiled softly. Next to her, Reiko had a similar smile on her face.

"Thank you."
After saying this and drinking the tea, Jin asked Lao-kun to do the calculation.
"Old man, how long do you think it will take for the shrapnel to affect Ars?"

"Yes, 300,000 kilometers, until it enters and leaves the inner orbit of the moon.
1,000 seconds, or just under 17 minutes.
"If we can put up a strong barrier for 30 minutes, we might be able to lessen the impact.
"What kind of impact do you think it will have, Brother Jin?"

Erza, who had remained silent until now, asked a question.
"There might be a slight effect on gravity. Then, detached fragments may fall on Ars. Or the atmosphere of Ars could be taken away by the debris. ......"
"None of this is good."

Elsa said with a frown.
"Yes. I was wondering if we could put up a barrier between us and the debris to prevent that from happening."
"But wouldn't it have to be pretty big?"

"Yes, but it would have to be very large. I want it to be at least 100 kilometers in diameter. If possible, about 1,000 kilometers.
When Elsa heard the words "1,000 kilometers," she was taken aback by the sheer size of the project.
"I think the moon (UNY) is 1700 kilometers in diameter, so ......!"

"Yeah, that's pretty big."
"I don't think it's quite that big."
Erza tried to imagine the amount of magic power that could be supplied by such a large barrier, but she had no idea.

"Well, it's about the same amount of free magical energy (ether) that is consumed in Ars in 100 years.
"That much?
"Yeah, that's what you get when you increase the size."

Jin looked as if nothing was wrong, but inwardly, he was worried about the amount of money he was consuming.

"It is not often noticed, but the compression effect includes the alignment of the phases of the magic power to increase its efficiency. That's what we need in this case."
Erza thought for a moment and nodded.
"The same idea as a laser beam."

"That's right. Sunlight is an incoherent light, while laser light is a coherent light. In other words, the efficiency is different.
"I think I get it."
"It will probably consume three to four orders of magnitude less."

That much?
Yes. Yeah. But it's hard to control. I'll have to ask Golem to do it for me again."
Still, there was a glimmer of hope.

"Four digits is a lot."
1 x 10 to the 10th power = 10 billion and 1 x 10 to the sixth power = 1,000,000,000.
I think we can do something like this.

Hearing Erza's muttering, Jin also remembered something.
"I remember someone saying that standing on your head is a good way to get an idea.
And.

Erza puts Jin's body first since it's not a time-sensitive situation. The same goes for Reiko.
After a proper dinner, Jin enters the workshop.

There are only five days left until the debris passes through the vicinity of Ars.
