It was 2:00 p.m. and Jin, Elsa, Reiko, Hope and the others were exploring the town of Coco.
"There's a pump, isn't there?
Reiko said.
"It seems to have been manufactured only recently, though."
The pump was the first one made by Jin in the village of Kaina.
It seems that these tools were not destroyed by the League of Magic.
"Is it necessary to evolve not only magic tools but also mere tools more and more ......?"
"Aren't those things imported from Mitsuho?"
Erza responded to Jin's mutterings.
"Maybe so, but for some reason, tools from Mitsuho don't seem to be widely used."
Take bicycles, for example.
They are widespread in Mitsuho, but not at all in Shoro and other small countries.
"Maybe it's just a matter of taste."
Erza says, but Hitoshi doesn't think that's all it is.
"Hmmm... ......"
I think it's too vague to put it all together as a preference,
"I wonder if something that doesn't use magic at all would not be well received?"
Jin says with a thought.
"Well, that might be a possibility.
In the case of the pump, it was accepted by the general public who cannot use magic, but in the case of the bicycle, the target market is the wealthy and above, so it is different in that respect.
"It's difficult to develop a market, isn't it?"
"Hmmm..."
Talking like this, Jin and Elsa continued their tour of the town.
"Oh, a car."
Erza pointed toward a Golem car.
"I don't know that type," she said.
"It was probably made in the Shoro Kingdom," Reiko told me.
Reiko told me.
"I see, they are becoming more and more popular.
"They use magic, don't they?"
"Well then, would it be more popular if they were magic bikes instead of bicycles?"
I don't know about that.
Jin's final decision was that it would be difficult to popularize the idea, since people who could not ride a bicycle would not be able to ride a motorcycle.
He continued to tour the town, but without any further success.
Not many ideas for tools and magic tools came to mind, and Jin and his colleagues returned to <> at 3:30 p.m. "What I've been making so far," he said.
"I feel like most of the things I've made so far have been driven by necessity," said Jin, as he sat down to tea in his room.
Jin muttered to himself as he sipped tea in his room.
"Well, that may be true.
Necessity is the mother of invention.
Perhaps that is why it is not easy to spread the use of something that is brought from somewhere else because it looks convenient.

Since there seemed to be many overnight guests, Jin and Erza decided to use the bathroom, even though it was still light out.
The bathhouse is in a separate building and is quite spacious. In this cold season, it is nice to have a bath.
If the inn did not have a bath, Jin would have returned to Horai Island by the warp gate to take a bath.
"Ah, it's nice hot water.
It is now 4:00 p.m., and no one has used the bath yet, so Jin is the first one to take a bath.
The same was true for Elsa, who enjoyed her bath without being disturbed.
The dinner was a traditional meal of the Franz Kingdom, and both Jin and Elsa ate it all, remembering the old days when they came here with Zion and the others.
Then, while relaxing in their room, they decided to ask Reiko about the .
"Well, let's see... ......"
Reiko began to talk.
"The name 'hanabi' comes from Mitsuho," she said.
Indeed, Mitsuho is quite culturally influenced by the <>.
<
As a medical student, Shuki Tsetsi, who also had a good knowledge of chemistry, could have reproduced fireworks.
Or, it is quite possible that he had passed down the concept and someone reproduced it in later times.
That is what Jin imagined.
However, the fact comes as more of a surprise to Jin.
"It was your father and Saki who recreated the fireworks ...... in this world."
"What!"
According to Reiko, 400 years ago, when Jin...... was exactly 40 years old, Saki, the old lord, <> The " Elsa" is the name of the woman who was the first to make the "Smith".
"......Erza, you knew about this?"
"...... nn. I'm sorry I didn't tell you. And I have no idea how it came to be launched here ...... at the gateway to the Klein Kingdom, so..."
"I see."
Jin didn't pursue the matter any further, since I remember he had only wondered during the day why they were doing that here, but never said anything about who made the fireworks.
"So, your father is wondering why you set off fireworks?"
"Yes.
"It started as a signal that the border was safe."
Jin nodded his head and said, "I can sort of understand that. In the absence of any means of communication, this kind of visual communication is quite effective.
Four hundred years ago, the kingdoms of Klein and Franz had been in repeated skirmishes until the Lafayette family took over the throne.
This is probably why this means of communication was chosen.
"Even after the peace was established, the "wolfsbane" continued long afterwards as a sign of peace and tranquility within the borders."
Reiko said it became a mere event, and at one point an attempt was made to change the color of the smoke.
"I see."
"But it seems that it was quite difficult to color the smoke."
"I suppose so."
"So a certain engineer, whose name has not been passed down, turned his attention to fireworks."
"So that's what happened. ....... And here we are.
No, it didn't happen right away. At first we were setting off fireworks in the daytime.
"Oh, they weren't very visible."
Jin laughed inwardly, thinking that fireworks in the daytime, no matter how beautiful they were, would be a waste.
"Yes. So we set them off at night and they were so beautiful that we started setting them off at night.
Jin was finally convinced.
"In the last 100 years or so, when peace prevailed, we no longer set off the <>, and the custom of setting off fireworks for two days only remained during this season when the air is clearer.
"It's not summer there, is it?"
"I heard that the wind blows unexpectedly in summer."
Jin was convinced that strong winds are not acceptable when setting off fireworks, and he understood the reason.
What about these two days?
"I heard that the engineers who made the fireworks decided on this, but I don't think they were properly informed about it. I'm sorry."
No, it's okay. It's okay. I'm convinced for the first time.
Jin thanked Reiko and the old man who had compiled the information.
