"Jin, what's wrong?"

Reinhardt noticed that Jin was acting strangely and called out in a concerned voice.

Jin had a bead of sweat on his forehead,

"This is ...... a huge warp gate," he said.

He said, "What?

"What?

Is this a warp gate?"

Reinhardt and Erza were surprised, but it was probably Lukoil who was the most surprised.

"What, what, what?　This is the Warp Gate?　How could you possibly know that?

His face turned red and blue, and he stammered, finally saying just that.

"Why, because I know ......, that's all I can say."

Jin had been deceiving himself by saying that the warp gate he had been using was an ancient relic (artifact), but now the warp gate as an ancient relic (artifact) definitely appeared here.

"Ummm...ummm...ummm...ummm......... You can easily detect at a glance what I couldn't even understand after 10 years of research?　That's absurd!"

"No, I'm sorry.

Jin apologizes to Lukor, who is excitedly ranting, not understanding what he is saying.

"Oh, look, you see that part of the magic circle where the paving stone is broken?　Isn't that evidence of a warp gate?

I tried to tell him, but he became even more confused.

"I don't care!　There is no magic circle for a warp gate!

It seems that nothing he can say will make a difference now,

Jin-kun, let's go!

Erza pulled on Jin's sleeve. Jin also decided to leave the situation alone for now and left the room.

"So, if this is a warp gate, it's ...... huge."

Reinhardt sounds impressed.

"Yeah. I didn't know there was such a big warp gate either. Well, it looks like it's already dead.

Jin says. However, the air conditioning still seems to be working, albeit imperfectly. It is cool in summer and warm in winter. I could understand if it were a cave, but in such a shallow place, it makes more sense to think that the air conditioning is working.

Reinhardt asked Jin as he was thinking about this.

"Jin, what do you think such a big warp gate is used for?

"Judging from its size, a large amount of supplies or a large number of people, I guess.

Reinhardt nodded in agreement,

"I think so too. I think it was probably one of the strongholds of the war of wizardry.

Jin agreed with him. Jin agreed with him.

"I see, that's a strong possibility. ......"

Then Lukor, who had recovered, interrupted.

"You guys!　You think so?　That's the same conclusion I've come to over the last 10 years!　This place must have been a provincial fortress during the Magic War!"

"Ha, ha!"

The excited Lukor's argument continues.

"The War of Magic!　It was a war for survival between demons and humans!　The demons were strong and the humans were weak!　But the humans have not perished. Why do you think that is?

Lukor asks Jin. Jin answers without knowing why.

"Is it the Aether Stampede?"

He was right.

"Yes!　Aether Stampede has caused the free magic element (ether) in the atmosphere to disappear, even if only temporarily. The demons cannot survive without free magic element (ether). But human beings, with the exception of powerful wizards, can live without free ether.

Jin felt a chill run down his spine when he heard this. If another "Ether Stampede" were to occur now, Jin, Reinhard, and Erza would not be able to survive. And Reiko would probably be immobilized as well.

"Is the method of 'Aether Stampede' transmitted?"

Jin asked her that question.

"Hmm?　No, no, the technology before the magic war, including that, has not been handed down for the most part. That is why I am investigating these ruins!

Jin is relieved for the moment. There seems to be no danger for the time being. But..,

（However, Jin thinks to himself, "It might be a good idea to think about countermeasures against the "Aether Stampede".)

) Jin thinks to himself.

Reinhardt asked Jin another question.

"Hey Jin, if this is a fortress, what do you think there is besides the warp gate?"

"Well, command center, living quarters, infirmary, pantry, and ......."

Jin spins his words in thought, and finally, after a little hesitation, he says, " armory,

"...... armory," he said.

Reinhard said.

Reinhardt nodded in agreement with Jin's words.

"I think so too. I think there are weapons from the past hidden somewhere in these ruins.

Then he continued his words.

"I can't help but think that if they were to fall into the hands of that , I would ......."

Now Jin finally understood Reinhardt's concern.

"Indeed. I hope it's not there, but if it is, we have to do something about it.

Jin agrees. Then he looked around at the wall,

"If this is the warp gate room, it's like a doorway. It should be on the first basement floor or the first floor above ground. If there is such a warehouse, it must be in the basement, so it must be on the same level or in the basement.

Lukoil interjects again, "No, no....

No. There is no other room. There is no other room. I can use a little magic myself, I tried to find it. I've tried. But in vain. There is no other room.

Jin tried to refute this. Jin tried to argue with him, but he thought better of it and kept his mouth shut. Reinhardt took his place,

"Well, that's all right then. Well then, if there is nothing more to see, let's get out of here.

Jin and Erza agreed. Jin and Erza agreed, and the group went out of the ruins, leaving the still mumbling Lucor behind.

The sun was shining brightly outside. The old man who had shown us the way was gone.

"Well, what are we going to do for the night?

Reinhard said. Erza heard that,

"What?　Aren't you going home?

She looks doubtful. Jin quieted her down.

"Well, let's go to the carriage. We'll talk about the details inside.

With that, the group strolls back to Jin's carriage. It was a pleasant afternoon with a spring breeze.

"Well then, let me explain."

They returned to Jin's carriage, sat down in the cabin and closed the door.

"Reiko, keep an eye out for anyone approaching.

"Yes, father."

Jin gave a final warning and urged Reinhardt to start talking.

"Okay. Erza, you heard about the Unifiler the other day, right?

"Yes.

First, let's start with an explanation to Erza.

"The Unifiler is planning to revive the Dinaric Kingdom. In other words, they want the lost technology as much as we want it.

"I understand."

Jin then took over and began to talk.

"If those ruins are the remains of a fortress from the past, it's definitely not just that room. I can assure you of that.

You mean...

Yes. The armory will be there. And the technology of the past.

At this point Reinhardt took over again.

"Normally, it would make sense to contact the appropriate department in the Kingdom of Egelea and have them investigate... but seeing as the situation has been left unattended for decades, it seems that at least the people in Ulemlin are all incompetent."

Uremlin is the nearest regional city. Reinhardt has a way with words.

"And that Lukor guy is suspicious. Too suspicious. Why would it take 10 years for one room like that?

Jin agrees. It's just not right. Reinhardt sums up the conversation.

"For now, I'd like to take steps that won't benefit the Unification Party (Unifiler)," he says.

Jin agreed with these words,

"Yes. They are the kind of people who try to manipulate Reiko and the golem that others have made. We don't know what kind of dirty tricks they might use. I think we should be the first to go.

He said. Finally, Reinhardt said,

"Besides, I'm interested in ancient technology!

Reinhardt concluded. Erza's shoulders relax after hearing this.
