Jin tells a worried Erza in a cheerful voice.

"Erza, the current confirmation experiment only proves that an efficient energy transfer cannot be achieved by extending the conventional method. Then I'll just have to do it my way."

"What?"

"There are several ways. You can transfer a bottle of ethenol or send a mana cylinder.

"Indeed.

"Up until now, we've been obsessed with the idea that such a method isn't smart. But not anymore.

If you know for sure that the path you are on is a dead end, you can just go another way, Jin says.

"I can see that."

"So let's think about it. I wonder how we can be more efficient.

"I'll think about it, too."

Jin seemed to be enjoying himself somewhat, and Elsa decided to join him in thinking about it. The first thing I can think of right now is ...... a bucket relay."

"?"

Erza heard the word and a question mark appeared in her head.

"A bucket relay is ......"

Jin explains to Elsa.

"It's when a couple of people fill buckets with water and hand them off to each other to put out a fire or something like that. I don't know the details ......."

I said < with an image, but Jin has never done it either.

In the first place, what we are talking about now is energy transfer.

"In other words, we put concentrated free magic element (ether) in a <> and send it out through the transfer gate (warp gate) by using, for example, a golem. The golem receives it at the receiving end and transfers the free magical element (ether) to a tank or something like that. ......

"Is that why you said earlier that we can use ethenol and mana cylinders?"

"Of course. I was thinking that such a would be possible."

Elsa nodded.

"Certainly, it is possible. If we can figure out how to do it efficiently ......."

But Jin interrupted Erza.

"Wait, wait. We're not finished yet. There's one more thing."

Can I hear it?

"Of course. The other way is to use the transporter.

<

It takes time and effort to determine the coordinates of the destination, but the problem is solved if there is a target <>.

"That sounds doable.

"But I don't think we can send <>.

"Only objects, you mean?"

"That's right."

It's a natural thing to say, since it is a derivative technology of the warp gate.

"Then, why can't we send only objects ......?

"Yes. After all, it's the same as a transition gate (warp gate) ......."

"It's difficult."

Jin and Erza both thought about it.

"Right, Brother Jin?"

Erza, who seemed to have an idea, opened her mouth.

"The energy you want to send is free magic element (ether), right?

"Well, yes. If free magical element (ether) is not possible, then we will have to use magical element (mana). ......

But Erza shook her head.

"No, that's not what I meant. Free magic element (ether) is more convenient, I think."

"...... yes."

Unusually, Jin still had no idea what Erza meant.

"Why don't you start with the technology of freely manipulating free magic element (ether)?"

"Eh ...... Oh, I see..."

"For example, sending a lump of free magic element (ether) to a targeted place.

So far, technologies related to free magic element (ether) include <> and <>.

"Then, we might be able to come up with a way to send out free magic elements (ether)."

< can be done in a pseudo way, but we have been feeling a dead end in that approach.

"Well, let's give it a try."

"Hmmm..."

In order to handle free magical element (ether), we need a .

There are few high quality ones left that can be used for human body, but I had a considerable amount of those found at the Gigantopod Ranch in the depths of the earth.

"Now that I've calmed down a bit, I'll have to report to His Majesty about this incident. ......"

>? >>

"Yes, ......, I'll let you do that."

The old man and Jin decide to report to the emperor that Makina has worked out a solution to the problem.

Makina was to be moved by the old lord and sent to the Shoro Empire.

On the other hand, we could not leave Sion and Marikka alone so long.

After the policy was decided, Jin moved to the village of Kaina with Reiko. Erza said that she would think about it more at Horai Island.

Zion was reading a book in the library of Nido Castle.

"Ah, Jin, it's been a while.

"It's been a long time... ...... well..."

Zion told me it had been a long time. The last time I saw him was on October 30, and now it's November 2, so it's been two days.

"So, how are things on Onogoro Island?"

"Well, it's not going well."

Jin explained that three saucers and were chasing each other.

"...... Jin is taking his time too. ......"

Zion was a little taken aback.

"Well, I don't know," he said, "but it's a question of what they're going to do, and if something happens to this planet, we'll be in big trouble.

"Well, that's true."

<.

That is why we are hurrying to gather information and improve our defenses.

"I wish I could help you.

Sion turned his head down.

* * * * * *

"Hmmm, that airship seems to be just running away.

Gyoi. Are they playing with it?

No, they may be trying to find out information about us as we are trying to find out information about them.

What should we do, then?

Those three planes are just toys. It doesn't matter if they're destroyed or captured.

But still... ......

You're not satisfied?

Yes.

You speak like a human being, don't you?

I'm ......

I'm Suit yourself. I'm tired of it.

So you'll leave it to me, then?

That's what I said.

Thank you.

Thank you.

Jin was in the library of Nido Castle when he received a message from the old man.

"I see!"

There is a warp gate on the 3rd floor where the library is located.

Jin got up from his seat.

"Jin, can I come too?"

Zion rushes to Jin's back.

"Yes, but I think Marikka will be worried.

"Oh, I see. ...... Well then, I'll go after I talk to Marikka!"

<, have been given the location of the warp gate and the bracelets of their friends, so they can use them without any problem.

By the way, Zion's bracelet is silver and light blue marbled, and Marikka's is silver and yellow marbled. They are silver and light blue marbled bracelets for Zion and silver and yellow marbled bracelets for Marikka, matching the color of their hair and eyes.

"Old man, what happened?

Jin and Reiko ran into the Horaijima command center.
