On the afternoon of June 10th, Reinhard, Bertsche, and Saki returned to their home in Shoro.
"I'll leave the warp gate in Saki's barn for the time being," Jin said.
Jin said, and Saki nodded in agreement.
"Oh, I'd be glad to do that.
"It's close to my house and not many people come here."
Reinhard nodded.
"I wonder if it's a good thing that we don't get many visitors?"
Saki smiled to herself.
"Well, I think it's a good thing this time ......."
Jin had no choice but to follow up.
"Well, anyway, I'm glad to know that I can go to Horai Island anytime I want as long as I have these glasses.
The lenses have been replaced with magical crystals.
Magiquartz is the material used for Reiko's eyes, and has a weak optical property. It is characterized by its ability to change its refractive index with magic power.
"I can see far and near very well, can't I? I never thought this day would come.
In other words, they were bifocals.
Since Saki is nearsighted, she can use a higher power for distance vision and a lower power for close-up vision.
Although Saki's magic is weak, she can do such a thing, and she soon got used to them.
Saki was so used to it that she couldn't live without it now.
"What?
When Reinhardt returned home, he was surprised to hear that this year's < would be held in Koju, a town on the other side of the river from Banneh.
He had expected it to be held in the capital, Leusert.
"I see, you were out of the country and didn't know about it.
Wolfgang, Reinhard's father, said with a surprised look on his face.
"I thought you had heard about it in Leuthart. I thought you were listening in Reuthert. ...... Well, that's all right. You will be there, of course?
"Yes. And Jin, and Saki.
Wolfgang smiled and nodded.
"Okay. I'll apply for theirs. I'm looking forward to seeing what you have in store for us, Jin-dono.
"Oh, and Jin is bringing an assistant with him, so please apply for him as well.
Assistant?
An assistant.
Wolfgang did not inquire further and Reinhard did not elaborate on the assistant.
"......, so we've secured slots for Jin, Erza, and Saki."
Jin heard this in Reinhardt's room.
"Well, that's great."
"So, what is Jin going to exhibit?"
Reinhardt asked while sipping the tea that Bertsche had made for him.
"You'll have to wait and see," Jin replied with a mischievous smile.
Jin answered with a mischievous smile.
"Reinhardt is on that ship, isn't he?"
"Yeah, I think I'm going to take out that hull ship. Then we can make a special golem for it.
It seems that Reinhardt had decided from the beginning to exhibit the ocean-going ship he had made in Horai Island.
He said that he had decided to exhibit the wheeled boat he had made on Hourai Island from the beginning, so he had used materials that were commonly available in the market.
The boat was too big, so Jin promised to carry it secretly later.
"Ten days to go. I'll make the golem in 10 days.
Reinhardt said he would make the golem in his workshop.
"Well then, if you need anything at all, you can always count on Horaijima.
Jin finished his tea and stood up.
"Jin, are you leaving already?"
"Yes. I want to make something to exhibit, and I don't want to interrupt the newlyweds.
With that, Jin and Reinhardt parted for the moment.
* * * * * * * * * * * * *
Jin checked the carriage at Saki's house and the warp gate attached to it.
"Oh, Jin, you're going home again."
Saki, who had just come outside, found Jin.
"Yes, I will be back on the 18th. Oh yeah, Reinhard told me that both Saki and I have already applied to be at the technology expo.
"That's great. I'll have to finish my paper then.
Saki told me that she was planning to submit a paper on the magic she had been discussing the other day on Horai Island.
Although the paper is not very popular, she said, there are only a few people who submit it, and the lack of new magical theories is considered a problem.
"<>," he wrote in the article. If you have any questions, I might be able to help you."
"Yeah, you can come anytime. Saki is part of the family.
"I'm glad to hear that. See you soon, Jin.
"Yeah, see you later."
Jin first transferred to the intermediate base Shinkai.
The warp gate of Shinkai is actually quite special.
Ordinary warp gates have a one-to-one correspondence between receiving and sending, but Shinkai's warp gate has a multi-correspondence.
The secret is the link core.
The link core usually connects warp gates on a one-to-one basis, but Shinkai's warp gates have multiple link cores.
By switching the link core corresponding to each warp gate, it can accept transfers from multiple warp gates and send them out again.
"This is more reliable, so I guess I can leave it as it is."
I have thought of switching the warp gate as if changing the frequency, but I have experienced firsthand the terrible consequences of making a mistake in adjustment.
It is only natural that we should place importance on certainty.
Aside from that, Jin flew to Horai Island and called Anne.
"Yes, Goshujin-sama."
After asking some questions to Anne, Jin started to make some complicated magic tools with Reiko and Anne as his assistants.
"Yes, there's a pump there ......."
"Make sure it's airtight."
This is the important part.
When the form was completed to some extent, he prepared a large amount of threads of the ground spider (ground spider), and using the original engineering magic he had created the other day, he integrated them. They further transformed it into a thin sheet by forming and made it into a large bag.
Next to her, Erza is thinking about it.
She is thinking about what to exhibit at Jin's request.
"Hmmm, here, like this ......" she said.
She seems to be doing a lot of trial and error. Jin decided to let her work on it until Erza asked her a question, saying that this is also an experience.
The first time, he was able to complete it.
"Okay, it's done!"
Meanwhile, Reinhardt was finishing the golem in his workshop.
"You made two of them?"
Bertsche, who had brought tea and snacks during break time, looked at the completed Golem and said.
"Oh, these two are <>.
"Twin, huh?
Twin, that is, twins.
"Oh. Each takes the right and left outer rings of the outer boat. It was difficult to synchronize their movements, but we were able to make it work with the we learned on Horai Island.
Reinhard had made some progress.
"So, what is your name?"
"A name or ....... I think I'll have Belle give it to me."
Reinhard smiled. Bertsche thought for a moment and then spoke his name.
"How about Mack or Mick?"
Reinhardt agreed without a second thought.
"Yes, that sounds good! Okay, let's go with Mack and Mick!"
