Jin was on the second floor of his house, leaning against the window and watching the moon. Reiko is with him.

Elsa is not here with her mother, Meene, for the first time in a while.

It was past 9:00 p.m. and Hannah was already asleep.

Reiko, whom he had not given much attention recently, was on his lap, and Jin lightly stroked her head, muttering to himself.

"That moon is strange, isn't it?"

"Father, what do you mean?"

"The fact that the moon never waxes and wanes while it is full means that the orbital period of the moon around this ars coincides exactly with the orbital period of this ars around Celan."

"Huh."

Reiko, who only knows about the moon in this world, may have some knowledge of the moon, but she doesn't really feel it.

Jin was not familiar with astronomy, but he had heard that there was a Lagrangian point between the earth and the sun, and that celestial bodies at that position were stable.

Jin digs up his memory, thinking that there must have been a famous robot animation in which a space colony was set up at such a point.

In fact, there is a Lagrangian point called L2 on the extension of Sun-Earth, and if the moon were located at the exact position, there would be a universal total lunar eclipse, which means that the moon would be in the shadow of the earth, and no sunlight would shine on it.

However, the moon Uni of Ars in the Celan solar system is a full moon. This means that it deviates slightly from L2, but Jin did not know that much about it.

"I heard that a planet called something is going to pass very close to us in six months. In a little while, we may need to try to build a spaceship.

"Are you going to space?"

"Yes. I have always wanted to go to space.

There is hardly a boy born and raised in modern Japan who has not longed to go to space.

But you have to get your feet on the ground first.

The mysteries of the underground and the case of Prince Oranjee are still unstable.

"But I don't think we have to make up our minds, do we?

Reiko advises Jin.

"Sometimes your father seems to be too disciplined, trying to keep order.

"Is that so?"

"Yes. Yes. Like, let's finish that one before we start this one.

Jin nods his head.

"Is that so?　I think there are some things we've stopped working on. Like the synthesis of substances. ......"

"The old man is taking over, isn't he? So it hasn't stopped."

"Is that what it is?"

Reiko encourages Jin.

"That's right. If you have so many things to do, all you have to do is to make the arrangements. That's why we are here.

Jin gently patted Reiko on the head.

"Thank you, Reiko."

"No, you're welcome."

Then Reiko abruptly changes the subject.

"So, father. What's it like to be on a spaceship?

"What?"

I'd like to hear about your father's idea of a spaceship.

This question came from Reiko, who knew well that Jin was fond of this kind of topic.

"Well, I guess so. I guess it would be basically spherical since it would be powered by a force field generator.

Yes, and?

"The control room will be in the center, and there will be a device to generate 1G, water recycling, ......."

Reiko is taking me for a ride, and I'm coming up with more and more ideas.

"The on-board machine should be something like Pegasus 1. Yeah, it would be nice if it came in various sizes.

Seeing his happy face, Reiko reminded Jin that the best thing for him is to make what he likes as he likes.

And the old man memorized all Jin's ideas that night.

The next day, Jin was playing with Hannah in the morning. The next day, Jin played with Hannah in the morning, partly to apologize to her for his recent injustice.

"Come here, honey!"

Hannah and Jin are on the and respectively, heading west along the Herme River. Reiko, using for the first time in a long time, was accompanying them stealthily.

It took an hour for the golem horse to move slowly.

"Look, here we are!"

"Hmm, it's a beautiful place, isn't it?"

"Yes, it is!"

Hannah led us to a place where the other side of the river is sheer. The layered cliffs, which must have been deeply eroded by the Ermee River, are magnificent.

Although Jin's knowledge of geology is limited to what he learned in high school, he still has an idea that the strata here are very valuable.

On the side where Jin and the others are, there are layered rocks, so-called "iwadatami" (rock pavement).

It reminded Jin of Nagatoro, where he had once gone on an excursion.

"This is a place where big kids often come. My grandmother allowed me to go because I was with my grandma.

Indeed, there are some places where it is dangerous to step off. Unlike the area near the village of Kaina, which is basically gravel and sand, this area is rocky.

"Well, let's start fishing, shall we?"

"Yes!

It is said that there are many river fish in this pool. When the water is getting a little warmer, we can catch Omasou, a fish similar to landlocked salmon.

This is a fishing rod made by Jin, who has slightly modified the long pole used in the village of Kaina to make it more resilient and strong.

The rod is made of ground spider line with a hook and line, and a hook made of light silver.

The bait is a river worm that sticks to the rocks on the bottom of the river when they are turned over.

Hannah, who grew up in a village, picked up such insects without a care and put them on the hook.

"Well then, you'll have to watch me, big girl!"

Jin has never done this before, so he first asks Hannah to show him how it's done.

"Yes!"

The hook was cast from the top of the rock pavement into the center of the deep pool.

There was no float attached. It was similar to what is known as "myak fishing.

"It's hooked!

Hannah set up her rod.

"It's a little small, but it's delicious when cooked.

The fish is put into a basket that has been prepared.

"Come on, you try it too," he said.

"Here it is."

Jin also took control of his rod and cast the hook into a good spot.

"Hmm?"

He felt a thump in his rod hand, so he set up his rod ....... It seemed to be a big one, and the rod bent like a full moon.

The rod bent like a full moon. "Oniichan, it's a big one!"

Jin pulled up the rod with all his might, knowing that the hook and rod he had made would not break or snap so easily.

"Wow!"

A big fish of at least 50 centimeters had come up. Hannah pulled out a hand net and scooped it up.

"Wow, girl!　This will be delicious grilled!"

Jin looked at the fish, which had bright oval-shaped spots on its sides, and thought it looked like a landlocked salmon.

The landlocked salmon is closely related to a freshwater fish called a trotter, which is similar to the loach.

The difference between the two is that the trotter lives in lakes and other bodies of water, while the omassou lives in cold water streams.

We decided to call it a day after Jin and Hanna had caught 15 and 17 omasu, respectively.

We decided not to be greedy any more.

We decided not to be greedy any more. Maybe smoked?"

Jin was thinking about how to cook it as he rocked on the back of his coma.

"How do you do a meuniere...... I think it's seasoned, buttered and baked?"

Jin tries desperately to remember. He tries hard to remember, because he has never made this dish very often.

"Oh yes, I remember to season it with salt and pepper, then dust it with flour before browning it in butter on both sides. Then sprinkle with lemon juice.

Jin seemed to have managed to remember and thought he would try it tonight.

Ramon instead of lemon should be available at Nido Castle, and if Martha's house did not have pepper, he could get some at Eric's store.

That night, Hannah, Martha, Mine, and Elsa all enjoyed the meuniere that Jin had worked so hard on.
