On the 9th, Jin and the others departed slowly, because many residents of Hatata came to thank them.
The usefulness of the pumps that Jin had built and transferred to the guild yesterday was evident to all who saw them.
The mayor, the chairman of the merchants' association, and the head of the innkeepers' association came in turn, which delayed our departure from 8:00 a.m. to 10:00 a.m.
What made Jin the happiest was a comment from the girl at the entrance.
Thank you very much, brother.
With just that one word, Jin fell in love with this town. It may seem simple to himself, but Jin really likes children. Not in a funny way.
The group was moving along the streets at a speed of about eight kilometers per hour.
Lunch was taken on the way.
Today's plan is to continue on to Amberg. It would be about 30 kilometers, or about four hours.
We considered going on to Lindau, but Reinhardt said that no matter where we went, we would be on home soil and that there was no need to hurry.
"Who said in Astan that they wanted to leave early?"
Matthäus was also disgusted.
"Don't say that. I'm feeling a little short when I realize that this trip is almost over.
"You're a cash cow, aren't you?"
But then he said,
"Well, Lindau, Fonde, Riale, and Leuthart. You will be reinstated in four days, so you may bid them farewell."
Finally, Matheus laughed.
Jin looked out of the window at the scenery.
The city of Hatta was dry, but so was this area. The area was the same here, except for a few succulent plants that seemed to be tolerant of the dryness, and rock and sand.
When I mentioned this to Reinhardt, he said,
"Yes, this is the driest area along the route," he said. The road that runs north-south through Lindau, where we will be staying tomorrow, is commonly known as the Trockenbahn.
"Trockenbahn, ......, that's a great name, isn't it?"
"Yeah, but that's also because of that pump. But that's going to be pretty much solved thanks to that pump."
Jin asks Reinhardt.
"Doesn't the Shoro Kingdom build irrigation canals?"
"A canal. ......"
"Yeah, what about it?"
"There is a good source of water around here. ......
Reinhardt nodded, but pointed out some problems.
"I don't know much about geography, but Reinhardt can tell you ......."
This is half a lie. There was a very detailed topographical map of Horai Island made by the Sky Golems, and Jin knew that there was no water source in this area of the Shoro Empire that could be secured.
"It might be a little impossible. There are well-developed canals near the capital.
The capital city of Leusert has two large lakes, Lake Tosmo and Lake Siouxsieu, and is well served by water transportation.
One of the reasons why Erza participated in the Golem boat competition held in Potrock before was because the Randall family's estate was located on Lake Tosmo and she had been familiar with boats since she was a child.
(I wonder if it would be possible to transfer water using a warp gate (......))
Jin had been thinking about such a thing. At the moment, the warp gate cannot continuously send out an object, so a big improvement is needed.
(But it is a worthwhile theme to think about.)
(But it is a worthwhile subject to think about.) Jin was being rocked by the horse-drawn carriage while thinking about this and that.
Then, a strange plant caught his eyes.
It looked somewhat like a bamboo, but the leaves were different. They are not thin like bamboo, but palm-like. But the part of the trunk is cylindrical and its surface is green and smooth.
The thing that resembles bamboo the most is that it has something that looks like a knot.
"Reinhard, what is that plant?
Jin asked,
"I don't know, I don't know its name. It is a plant that is common around here.
The only answer he received was, "It's a plant that is common around here. Even Reinhardt did not know everything.
"Hey, Matheus, can you pick one of those plants for me?
Reinhard calls out to Matheus from the window of Jin's carriage. Immediately Matheus cut one of the plants with his sword and brought it to him.
Reinhard thanked him and took it through the window of the carriage.
"Here, Jin, would you like to take a look?"
Jin stared at it.
As expected, it was hollow inside. However, the part that looked like a node was not a node at all, but merely a bulge from which a branch could grow.
If it were a real node, Jin thinks, "If it were a node, I could make a water bottle or a piggy bank. But then he thinks to himself,
"Can't we use this for pipes?
Reinhardt immediately denies it.
"Oh, that's no good. It shrinks when it dries and swells when it contains water, so its dimensions are not stable.
"I see. ......"
The plant was more useless than I had expected.
"It can't even be used as a water pistol. ...... The only thing it could be used to make is a string telephone."
As Jin muttered to himself, a flash of inspiration came to his mind.
(A string phone! (...... string phone or ......)
A string telephone is a toy consisting of two tubes with a piece of paper attached to one side and a string attached to the center of the paper, which is used to talk to each other.
The principle is that the voice of the speaker shakes the paper, and the vibration is transmitted through the string, which shakes the paper attached to the other tube and reproduces the voice.
(If you want to do this with magic, go to ......)
"Jin?"
Reinhardt realized that Jin had thought of something and fell silent. Fortunately, Jin is able to gather his thoughts.
(If we use a thin line of mithril instead of a string, we can transmit the vibration of free magical element (ether). Vibration of free magic element (ether) does not decay. ......)
The reason why they decay is that they are subject to resistance. Since free-magic element (ether) is considered to be a particle smaller than an atom, there is nothing to disturb its vibration.
Therefore, it does not decay (in fact, it seems to decay very slightly, but it does not matter on the order of 1000 km).
Also, unlike the string of a telephone, there is no need to keep it tight.
(It is easy to change voice into free magical element (ether) vibration at ......, and vice versa. And vice versa.)
Now, Jin has arrived at the free-magic element (ether) telephone string (not ).
(But I'd like to talk to various people on the phone, not just to a certain person. ......)
The manacam (manacam) used to change the equivalent of frequency to talk to a specific person. This is the basis of radio communication as Jin knows it.
(How does a telephone work? ......)
The orphanage where Jin was staying had a black dial telephone.
(Let's see, I think, you choose the person you want to call according to the number you dialed, right? (Well, I think they used to call it a switchboard operator, though it was a machine that selected the number. ......)
Jin tried hard to remember the old telephone story that he had heard from the Director.
(Yes, you call the switchboard first, tell the person you want to talk to, and the operator will connect you!)
) As long as he knew the approximate procedure, the details did not matter. Jin's plan was proceeding at a breakneck speed.
(Ah, the manaphone we gave out via Nostalgia last time would be less ...... in number if we use the switchboard, or is that too blatant?
The "Mere Old Man" thought that he could listen in as much as he wanted if the switchboard was the "Mere Old Man", and then he realized that he was listening in after all and burst out laughing. Reiko, who was standing next to me, looked doubtful.
(......) You've lost your train of thought, haven't you? The exchange table should be human, and then ...... yes, it could be done.)
Before the carriage arrived at Amberg, Jin had finished putting together the idea of a telephone ...... or rather a .
Amberg was a town about the same size as Hatta.
The lack of fences or walls indicates that the area is peaceful.
The carriages were parked at the entrance of the town, and Jin and the others were about to step into the town when they heard the following words.
"Mr. Reinhardt, and Mr. Jin, are you sure?
Some men appeared. Reiko immediately turns in front of Jin. The covert maneuver force (SP) was invisible to the human eye, but it got behind them, ready to attack at any moment.
Matheus put his hand on the sword at his waist and his men were ready to draw their swords at any moment.
"Excuse me, did I startle you? I am Raimer Gebhardtov, head of the Guild of Magi Engineers here in the city of Amberg. The others are also employees of the guild.
The man in the middle, a man of advanced age, bent at the waist and greeted us.
"Look, guild leader, I told you so. It's not polite to stand in a large group.
This was said by a young man about the same age as Jin, who was standing next to Reimer.
"Yes, yes, but I would like to meet the Magi Engineer who created those wonderful tools as soon as possible!
Reimer Gebhardtov said to the young man and turned again to Jin and the others.
Coates-Laudite from Hatata sent me word by pigeon, and I am anxious to meet you as soon as possible. I wanted to see you as soon as possible. Forgive my rudeness.
