The location was decided to be at the training ground between the 3rd and 4th walls.

< is also located between the 3rd and 4th walls, but at a much greater distance.

The location was chosen to be the furthest from human habitation.

"This is near the center of the training ground. It is far away from the houses and it is not likely to cause any casualties.

King Cesar said.

In the end, King Cesar, SS Commander Kirk Apted, First Military Minister Ragaed, First Technical Minister Latant, and others came along.

Jin is accompanied by a and Jix by a .

Erza is with her doppelganger. Donald is not here, by the way.

"Brother!"

Then the carriage arrives.

"I'd like to introduce you. This is my brother Ganno.

In the carriage was a dull-colored golem.

"First of all, please take a look. As you can see, we can have a golem of the same type as the phantom in no time at all.

"Hmm, I see. I admit that it is an advantage.

First Technical Director Latant nodded.

Jix briefly explained to his brother Ganno what had happened so far.

"Brother!　So, if we win this match, will we have achieved our long-cherished dream?"

"Well, yes. Well, it's only the first step, but at least our golem will be adopted.

Good luck!

I know.

With all the faces assembled, it was time for a mock battle.

"As for weapons, I have prepared iron bars as you asked.

Ragade, Director General of the First Military Ministry, asks them if they are sure.

"Yes. If it has a blade on it, it would be dangerous, and wooden ones are not strong enough.

Jin (his doppelganger) replies, and applies just in case.

and each take a steel rod.

"Please keep at least 50 meters away from the bars, it's dangerous."

Jin's doppelganger tells the Cesar kings. Everyone nodded in agreement.

King Cesar gave the signal to begin.

"Let's start ......!"

suddenly jumped out and delivered a lightning strike.

But <> dodged it with a comfortable margin.

But <> chased after <> even faster than in the mock battle.

"He's getting serious."

Jin's doppelganger mutters.

But <> is not yet in full swing.

His speed increased to the point that it was clearly visible to the onlookers.

* * * *

"......Which technology is superior to the technology of 50000 years ago, and which is superior to the technology of 1000 years ago plus the technology of today? Let's see which is better, the technology of 95,500 years ago or the technology of 1000 years ago plus the technology of today's Japan.

Jin, who was staring at the magic screen on Horai Island, said to himself.

"<> versus Adriana's!"

Jin seemed to be getting stressed out from just watching the game.

"Steward, when you're done checking out your opponent's moves, you can go all out!"

Hearing this, Erza asked Jin a question.

"Brother Jin, won't your opponent learn from you?

But his reply was a smile.

Don't worry. My martial arts are at the level of a soldier of the Shoro Empire. But I will increase my speed and power. You can't imitate me there, can you?"

"......, that's for sure."

You can imitate his technique but not his physical ability. Jin challenged the competition with his physical ability.

* * * * * *

Oh!

Your Majesty!　Please step back a little more!

When the aftermath of the battle between the two fighters reached King Cesar and his men, who were watching from about 50 meters away, SS Commander Kirk Aptt advised his lord to keep his distance.

"Yes, yes, let's do that."

Jin and Erza (their doppelg?nger) move back accordingly.

They are perfectly comfortable observing the two golems as long as they can see them from a distance, so they are in line with King Cesar and his men.

Meanwhile, Jix and Ganno are hiding behind the other golem, watching the battle between the two golems.

"Oh, brother, you're still amazing!"

"Mm. <

Do we need to use that?

"I don't know. Be prepared.

"Okay."

< and was becoming increasingly fierce.

The iron bars clashed against each other, sending sparks flying.

One moment they were locked in a fierce battle, the next they were bouncing off each other, and then they collided again.

With each step, fine gravel and sand scattered and the ground caved in.

"Ummm, this is what I call a <>!"

"This is making the mock battle look like a child's play."

"I guess there is always a higher power."

The Cesar kings look half surprised and half threatened.

<< "But, he's a good man," said the king of Cesar.

But what is the source of his power?

On Horai Island, Jin tilts his head.

< equipped with for such a long time, there is a high possibility that he has at least .

Then, Erza made an unexpected guess.

"Perhaps the fluid metal can store mana.

"Huh?"

Jin asked back for a moment, but when he realized what he meant, he thought seriously about it.

At the same time, the old man started to examine it.

And then he said.

"That is a possibility, isn't it?

"You think so?"

"Yes, yes. That's great, Elsa.

Jin praises Erza for having come up with the correct answer based on her experience and intuition.

"I'm glad I could be of help.

It is easy to make a mana tank by magically manipulating a magecrystal.

The gaps in the crystal structure are compatible with mana. It absorbs and releases mana just like diatomaceous earth absorbs water and oil, or activated carbon absorbs fine particles.

Metals, however, do not have these properties. Even if it is a .

Then, what did Erza mean when she said that it can store mana?

It was an inference from the that Jin had experimented with some time ago.

"Isn't that so?　Elsa."

"Yes.

In other words, he deduced that just as mercury dissolves other metals, the , whose composition is a mystery at the moment, can dissolve or rather store <>.

"I thought that if <> reacts to magic, there might be such a possibility."

Elsa's intuition is sharp.

"But first we have to beat him.

Since verification is not possible at the moment, Jin re-focuses his attention on the battle at hand.
