After lunch and a short rest, Jin again started to guide the guests.

"Well, this is the exhibition room about <. From here, I will let Elsa explain about the ."

As expected, Jin was too reluctant to explain his own achievements by himself.

"Thank you very much for your cooperation.

"Yes, Erza-dono, it's my pleasure."

The invited guests, unaware of Jin's intentions, listened to Elsa's explanation.

"The second generation inherited the knowledge and skills of the first generation, but not directly.

"Huh?"

"What do you mean?"

"...... Let the current Magecraft Meister explain it to you."

Erza wanted Jin to explain this topic.

"Then I will explain it to you. ...... Well, to call yourself the successor of <>, rather than ...... as <>, there is one obstacle, There is one obstacle."

"Hoh?　What kind of barrier is that?"

"It is ......"

<, but this is still a secret.

Jin then trails off.

"It is a certain engineering magic that can be used only by those who are candidates for successors ......, no, only those who can use it can become candidates for successors.

Jin apologizes, saying that the details of this magic are out of bounds and he cannot give any details.

"I see, there is such a magic ......."

"So if you can't use it, you can't even be a candidate for successor?"

In fact, there are quite a few engineers who can use low-level , so this explanation is misleading in a sense.

"Well, anyway, we used it to inherit the technology of our predecessors."

I see.

"So, not just anyone can become one."

At this point, Elsa again took over the explanation.

"That is why even the son of the second generation could not claim to be the third generation of Magecraft Meister.

(...... I didn't know that was the case. ......)

This is a fact that Jin did not pursue, and this is the first time he has learned about it.

"I see, so it is not a case of one child inheriting from another.

"In that sense, the candidates for the successor of the <> are Jin-dono, Makina-dono, and Marikka-dono of >, is that right?

Both Jin and Erza were relieved that they had been understood, or at least understood well enough.

Elsa's explanation continued.

"For some reason, the base of the <> is an absolute secret. One day, the second generation failed in their experiments and were transferred to the village of Kaina in the Kingdom of Klein.

"Oh, this is the present-day village of Kaina in the territory of Nido.

"The , who until then had lived a life cut off from the rest of the world, began to get involved in the world."

I see. The pump.

Yes.

A replica of the pump is on display. No, it is not exactly a replica, because it was made by the person who made it.

"After that, <> met Miss Beena, who later became known as <>, in the Blue Lands, and took her under his wing for a short time."

"Oh. An ancestor of ours, I see.

Marquis Logres Win Kuzma muttered happily.

He looked at the <.

"After that, I won the Golem boat race at Potrock."

There was a picture of a catamaran <> and the golem <>> that drives it.

"After that, I accompanied Sir Reinhardt, a diplomat of the Shoro Empire. Many things happened on the way."

A replica of the he developed with Reinhardt in Potrock is on display.

"The most important event was the Golem Party held in the Kingdom of Egelea.

"Oh, the incident caused by the Unifilers?"

"Mistress Leco......, I hear Sir Leco was very active."

"The Lotte he gave her is still a treasure of the royal family."

"...... But, jumping ahead a bit, when you were aiming for the Shoro Kingdom, that was destroyed by the first , wasn't it?"

"Oh, that's right."

"......"

Elena at the end of the line seemed to giggle a little.

"And <> arrives in the Shoro Empire, making <><><> and so on."

"Your Majesty, the Empress at that time, made a lot of arrangements for you, didn't she?"

Yes, she did. ...... Then, at the , he unveiled his and , and later won the , and was awarded the title of by the Empress. >>I received the title of "MagiCraft Meister" from Her Majesty.

"Ah, the tale has been passed down in my family as well. Sir Leco was very successful, wasn't he?"

Emperor Ernst II listened to the explanation with narrowed eyes.

"After that, the < was involved in many events and incidents."

It was also around this time that he resolved the friction with the , who were then known as the .

"I also participated in the construction project of the Shoro Empire's new ship, the , and provided the and exterminated the that arose from the ruins of the former Leonard's Kingdom."

Elsa's own brother Fritz was also very much involved in this, but that will not be explained.

"I also participated in the ceremonies held in the Kingdom of Selroa and became acquainted with the Crown Prince Cesar, who later became the king."

After that, he built a car and went to Mitzvah.

Then the World Congress was inaugurated.

This area is clearly recorded in the records of many countries, as he was already well known throughout the world as the <.

"After that, he took Elsa Randall from the Shoro Kingdom ...... as his wife and held a grand wedding banquet ......."

The wedding party was unprecedented in that it toured the Kingdom of Klein and all of the other minor kingdoms of the time.

"......Afterwards, the ancient ruins were discovered and seized as the present-day , and used as a base for the <>.

By that time, Jin's efforts had borne fruit, and magical engineering was flourishing in many countries, and competitions and exhibitions were held frequently.

Elsa's explanation continues: .......
