September 16.

Jin has returned to Horai Island.

He is thinking of going to the Principality of Mercana after this.

"The problem is how to explain myself. ......"

Jin thinks, "I don't know if they will believe me even if I explain.

"I don't know what I'm going to do with it," he thinks. ......

However, he still wants to say a few words before returning to his former life.

"I don't know what to do. ......"

Then, the old man gave his opinion.

"I think so too."

Reiko stopped him.

"Is that what you think?"

The old man began to describe the problems.

>

"U......"

Jin is at a loss for words from the start.

<

"Well, hey ......"

<>

"Indeed.

"......"

That was a very reasonable rebuttal.

>.

"Old man ......"

Jin thanked the "Mere Old Man" sincerely for his way of stopping Jin with a righteous argument.

>

"Yes, I guess so. ......"

Jin could use the peepers directly, but he would prefer not to, since it would literally be a peep.

* * * * * *

In the end, Jin decided not to visit the Principality of Mercana, following the old man's advice,

But he did not resist to ask the old man, "Hey, Mr. President, what do you think will happen to the countries of Ars in the future?

This is the only question that Jin could not help but ask.

<

The old man replied with a slightly out of focus answer.

"Well, do you think so?"

"Yes, I did."

Jin wonders if all Hourai Island can do for this planet is to watch over it.

Then he asks another question.

"...... And you're not going to tell me how my descendants are doing now, are you?"

<<

"I see. ......"

<<

Hearing this, a smile appeared on Jin's face.

"I see. I'm glad to hear that.

<

"......"

Jin closed his eyes and leaned back in his chair.

To return to the original time, four hundred years ago. That was his main goal, and it was about to come true.

"Everyone is at ......."

Jin's true place is not here, but 400 years ago.

But now that he can return home, Jin is beginning to wonder about the future of this Horai Island.

(Hmmm ...... what will the old man and Reiko do after I am gone?)

Jin used to think that the island would continue to exist with his descendants.

However, his descendants, for reasons unknown, seem to be living away from Horai Island.

(The current Horai Island will not change its way of being without my magic power, voice print, and authentication key (password), or rather, the order .......)

In other words, if Jin goes back to the original time, probably, Lao-kun and Reiko will act on their own.

(That would be bad. ......)

So, Jin comes up with an idea.

(How about a copy of me will be activated right after I disappear from this era?)

(How about that, right after I disappear from this era, a copy of me will be activated?) Without informing the old man and Reiko, Jin alone or with Erza's help, will make an automata with his memories, knowledge and personality, and hide it somewhere secretly.

Then, we can set the automata to start working when Jin returns to his own time.

（That's a good idea.)

The problem is that we can't consult with the old man or Reiko, but we can consult with the other members of the .

(Huh?) If that's the case, we can make it now.　(Then, is it OK if I make it now?)

(Then, can I make it now?) Jin felt that it is not necessary to wait until he comes back home.

"Hmmm... ......"

There is a question whether the old man and Reiko would welcome Jin as an automaton or not.

Putting that question on hold, Jin wanted to discuss with the old man something that had occurred to him while he was thinking about it, and he mentioned it to him.

"......Hey, Mr. President, is advanced technology...... or is heterogeneous knowledge and technology unnecessary on this planet?"

Jin was caught in such a thought.

"Civilization develops better when there are opposites. ......?"

In that sense, I suddenly think that the human race of the earth has always been in conflict with someone or something.

The three-stage argument is also like that,...... Jin thinks in his head, but it is actually a dialectic.

There are two opposing arguments, thesis (proposition) and antithesis (anti-proposition), and the process of reconciling the two and coming to a third synthesis (synthesis) = aufheben, roughly speaking, is a dialectic.

Jin imagined that the synthesis would become a new thesis, and at the same time, a new antithesis would be born and developed ...... and so on, repeating endlessly.

"There is a scientific civilization as opposed to a magical civilization."

Jin's musings continued.

"What emerged from the two was the Adriana system of magic, including magical engineering.

Naturally, this gave rise to a new conflict. That would be the <>.

In other words, the antithesis of <> is the <>.

Then what is the antithesis?

Jin was neither a thinker nor a philosopher, so he did not immediately come up with an answer.

Maybe it is something that the human beings of this planet, not me, should find out.

This realization made Jin feel a little better.

"Then, our role is over. From now on, we can live more freely.

Thinking this, his shoulders relaxed.

Jin decided to see if what he had always wanted to do would come true.

"Old man, is it possible to move Horai Island to ?"
