The next morning.

The next morning, the time was measured to be approximately 12 hours, and it was found that one hour in the Ars world is 1.02 times as long as that of the earth. Assuming, of course, that he was not crazy.

"Then it is within the margin of error.

I was originally more concerned about whether the watch could be used in Ars than about the time difference from the earth.

The difference between the day and the month on mechanical watches can be as small as 30 seconds, and most of them can be adjusted plus or minus a minute or so.

We can adjust that part a little wider.

Since this is a 12-hour watch, half a day = 43200 seconds. Multiplying by 0.02 gives 864 seconds.

"So we can delay the time by 864 seconds per half day."

Jin thought that he would have to leave it to the old man and the mini-craftsman (Smith) to adjust the speed regulator and find the optimum value.

"Brother Jin, let's go to breakfast.

Elsa came to call him this morning. Jin took the box containing his watch and went to the cafeteria.

Good morning, Mr. Nidou. I hope you all had a good night's rest.

Fadon was waiting for him in the cafeteria. There was a girl sitting next to Goose.

Her name is Nalie, and she is a quiet girl. She was still silently following Goose.

"Good morning. Your watch is fixed.

Seeing Fadon, who probably would not have eaten if he had not given this to him, Jin held out the watch box he had brought.

"Oh ......!"

The cracked glass had been fixed by <, and the dull case was now shining with the luster characteristic of chrome plating.

"Thank you!"

Fadon's joy was a joy to behold.

"Well, you are so excited like a child. You're in front of our guests and ......."

From the side, someone who seemed to be his wife rebuked Fadon for his exuberance.

"My wife, Fradecchi, is .......

Despite her occasional accent, Phrede was a small, vivacious woman. She and Fadon make a perfect couple. Nalie, standing next to Goose, is also smiling.

"Well, please enjoy your meal ...... while it's still cold.

"Yes, please eat ...... what's this?"

"What is ......?"

"What's this, girl?"

Saki and Erza looked at each other and Hannah asked Jin about the food.

"Oh, it's <>!"

"Natto?"

Yes, it was indeed natto.

Jin was convinced that they should be able to make natto, since they had round soybeans and rice straw.

Soy sauce and spices were also prepared, and Jin happily ate the natto before the eyes of the three who were hesitant to try it.

"Jin, can you eat it?

"It's a little stringy, but..."

"Onii-chan, won't it upset your stomach?"

"Ha-ha-ha, this is food. It won't upset your stomach. It's even good for you."

Guth, like Jin, had started to eat natto on rice. Nally, who was sitting next to him, also began to eat without saying a word.

"It might be hard for those who are not used to it, don't force yourself.

Hanna shook her head.

"I'll try it."

Then, following Jin's lead, she stirred it with her chopsticks, dribbled some hot pepper and soy sauce on it, and stirred it some more.

"The ...... threads are amazing!"

Hanna puts 5 or 6 pieces in her mouth with her eyes closed, muttering something like that. And then.

"...... Oh, it's delicious."

"What?"

"Hannah, is it good?"

Elsa and Saki look at Hannah with surprised faces.

"Yes, it's surprisingly delicious!

"Yes, it is.

"I'll try it."

The two begin to eat with trepidation.

"Can I have another one?

"I'll have another one too."

Beside them, Jin and Goose are having another bowl of rice.

* * * *

"...... not bad, but a little bit bad."

"Well, it was easier to eat than I thought it would be."

"Yeah?　It was delicious."

After the meal, the two men share their impressions of natto over a cup of tea.

"I missed it!

Jin was happy to enjoy the taste of the earth after a long time.

"I heard that this natto was also passed down by a wise man (Mags). It is said that Magus himself didn't like natto very much, so it is a food that is not for everyone's liking.

Guth then gave me an interesting piece of information.

"Thank you, Mr. Nido!"

Fadon, who seemed to have calmed down, came over. < to is a sign of gratitude.

"No problem. Oh, and turn the crown to wind the spring ...... power, but be careful not to wind it too much or the spring will break again.

"Yes, of course. If I know it's fixed, I won't move it!

Fadon says that he is very satisfied with the fact that the heirloom, which has been handed down from generation to generation, has been restored to its former glory.

In fact, it would be easier to keep the watch in good condition if it were moved, but since he treats it as a family heirloom rather than a clock, it is what it is.

Fadon also shared some interesting information with us.

"I will tell you something, Mr. Nido. ......In fact, my family has a that we seldom confide in each other. It is called ......<>."

Yamauchi?

No, it's Yamachi.

Despite the correction, Jin could not help but think that <> was <.

When someone mentions Yamauchi, Jin immediately thinks of Kazutoyo Yamauchi. He was a feudal lord of the Tosa domain in the early Edo period.

Jin had heard the name from a TV drama.

"In Fuso, we don't often say our <. We only tell people we are close to or recognize.

Guth explained to Jin. It is an unusual practice. It must be difficult to distinguish between people, Jin thought.

"I usually take my mother's surname, <>, because of my father's influence."

"Hmm. ......"

Aside from the customary custom, Jin kept in mind that this was also a fragment of a clue from the wise man (Magus).

"Nido-sama, can you read this?"

Fadon brought a small flat box. He thought it was another relic, but it was not.

"It seems to be a letter ...... written by a wise man (Magus) or someone related to him, but no one can read it.

In the opened box was a tattered piece of leathery paper that had been eaten by insects.

"......Fuso Dong, I left Mount Fu*s* and came here to **. The same person is **** and ****......"

It was difficult to read because it had been eaten and grazed by insects, but it was unmistakably Japanese.

"So you can read it!　After all, Nido-sama is definitely in the same country as the wise man (Magus)!"

"...... What's this?"

"This has been handed down from generation to generation. It was not given to him by Magus, but it seems to be a scribbled copy.

Jin thought that it might be a kind of road diary.

"Fuso," he said, "must be this country. Fuso, I guess it's this country. ....... I can't read it because it is eaten by insects, but I guess it is a mountain in the east of Fuso.

Jin concluded his explanation by saying, "I guess the rest is just a who's who of his companions, but since the original seems to be a scribble, I don't think we can expect much more to come of it.

"Hmmm ....... Mount Funisys, maybe?"

Goose interjected from the side.

"It's over 200 kilometers east of Fusor, north of the Hariri Desert. It's also the western edge of the Kruger Mountains. ......"

Goose said he had no idea where else to look.
