, a long-period planet, collided with the fifth planet Pengolta, changed its orbit, and disappeared into the far reaches of the universe.
However, even if the threat of the main body of the planet disappears, debris from the collision will attack Ars.
The predicted date is October 15, 3458.
On October 4, Jin was in Horai Island, racking his brains.
"Hmmm, what should I do? ......"
"Father, are you all right? You've been up all night, haven't you? Moreover, didn't you get a good night's rest the night before last?"
Reiko asks with a worried look on her face.
"I'm fine. I used to stay up all night for about two nights.
Jin answered with a slightly tired look on his face.
"...... Jin, at least rest your body for a little while."
Erza, who had also worked all night, brought him a cup of strong green tea to help him sleep.
"Oh, thank you, Elsa.
Feeling a little tired, Jin leaned against the back of the chair.
"...... wind."
But his eyes were staring off into the distance, as if he were out of his mind.
"Father, the tea that Erza-sama took the trouble to brew is getting cold.
"Uh, ah, ah, okay."
Reiko warned him and he hurriedly picked up the cup of tea. He took a sip.
"...... delicious."
"I'm thirsty, I thought. ...... pick some up if you like."
He also offers her a taro...... or, as the Shoro Empire would say, a as a teaside treat.
"Yes, thank you."
Erza had made them for him, as she knew he needed some sugar when his head was tired.
She was acting on the assumption that Jin would never eat a proper meal at a time like this.
He must have been hungry, because once he started to eat, he ate the takaimo one after another.
After two more cups of tea, he finally seemed to be satisfied with his meal.
"I guess I was hungry after all. Thank you, Elsa and Reiko.
After thanking them, Jin started to think again.
"Brother Jin, please tell me what the problem is.
"What?"
"I think it would be better to sort out the problem once."
Jin nodded at Erza's suggestion.
"That may be so. In a situation like this, it might be a good idea to change our approach a little."
Jin turned to Erza and began to explain slowly.
"What I'm struggling with now is how to deal with the fragments that are classified as <><>."
"Hmm, that's good. <> is for pieces between 1 and 10 kilograms, and <> is for pieces larger than that."
"Yes, that's right. So I'm wondering what I should do.
Jin takes a breath before continuing.
"There are two main methods. Either we can make it disappear, or we can change its trajectory."
"Each of these has its own problems?"
Yes. That's why I'm having a hard time.
Jin gathered his thoughts in his head for a moment and then spoke again.
"There are two ways to erase them, one is to turn them into plasma using a laser or something, and the other is to transfer them.
"Hmm?"
"Changing the orbit is still the same. Perhaps, if we change its trajectory even slightly, we can avoid a collision.
Elsa nodded.
"So each of them has its own problems?"
"Yes. ......"
Jin's shoulders slumped.
"First we have to transfer them. To do this, we need a huge amount of energy, because the thing is so huge. 21 <> and 1 <>. With the method at hand, it will be just in time or not in time, taking into account the time to generate mana from free magic element (ether).
