On June 20, the Shoro Empire was hosting the 12th Technical Exposition.

This is a four-day event that begins on the day of the summer solstice (usually June 20).

Until 3459, the exposition had been held every other year, but from this year, it was held every year. This year's event will be held in the town of Trom, not far from the capital.

It is located northwest of the capital, Leusert, and faces Lake Tosmo.

Saki, an alchemist, was putting up a display of her wares.

The items for sale were <(MPE) and (EMPE). .

"Come on, take a look!　These are the best materials for cushioning!"

This is Saki's second time participating in this event, so she is getting used to it.

"Wow, that's an interesting material."

Magi engineers are more interested in this material than alchemists.

"It would be good for seats of carriages, ships, hot-air balloons, and other vehicles, as it is lightweight.

Saki points to a sample made by Jin.

It is a sample of a chair seat that has been placed under the leather and cut in half with a <>.

I see, indeed. ...... but this sample is interesting. The structure is easy to understand and novel."

"Yes, I asked for the cooperation of the Magecraft Meister, a magical engineer."

"Oh, yes!　That makes sense. If ...... is the case, it means that <> is also paying attention to this material.

The name value of <> is huge, and Saki's booth is packed as word of mouth spreads and reputation grows.

Saki and Aaru are doing their best to give explanations, but it is all they can do to answer the questions being thrown at them from all sides.

* * * * * * * * * * *

"......Ugh......I'm tired......"

The first half of the first day was barely over, but Saki was exhausted.

"Hey, hey Saki, what's going on?　Do you want some Persica juice?"

Jin looked into the waiting room and called out to Saki, offering her a glass of Persica juice.

"Oh ...... Jin, I thought you weren't going to participate this year?"

Saki asked as she sipped the Persica juice she had received.

She knew that Jin was currently participating in the in the Kingdom of Elias and could not attend such an event publicly.

"No, I'm not going to participate directly, but I'm still concerned about various things.

On the other hand, Jin cannot use his "doppelganger" either. It would mean that there would be two Jin.

"...... and you've been tired since day one, haven't you?"

"Yeah,...... actually,......."

Saki explained that the show was more successful than she had expected.

"I see, you're a scream of joy, aren't you?"

"Yes, but ...... I won't be able to keep myself up for another two and a half days."

"I know. Okay, hold on a second. ......Reiko, call the old man and tell him to send two of the <> golems over here.

"Yes, Father."

Thirty seconds later, craftsmen 151 and 152 appeared in the waiting room.

"Saki, you can borrow these two during the exposition. They will be of great help to you if you transfer the necessary knowledge from now on.

"That's not a big help, Jin!　Thank you!"

Saki seems to be a little more energetic now that she's had some Persica juice and her helpers have arrived.

Saki seems to be a little more energetic now that she's had Persica juice and helpers.

"Is it easy to process?

How about durability?

What about the high price, which makes it impossible to use even the best materials?

Many people visited and asked many questions in the afternoon, but with two <> golems, Saki's workload was less than one-third of what it had been in the morning.

After all, the <> Golems can hear questions from more than five people and answer them in order later. They were so capable that Jin would have said, "What kind of Prince Shotoku is this?

"Thank you for your help, Craftsman Smith151, Craftsman Smith152.

"No, I'm glad I could be of help."

And so Saki managed to finish the first day.

* * * * * * * * * * * * * * *

The second and subsequent days were filled with visitors, but thanks to Smith, Saki's workload was small.

Thanks to the craftsman (Smith), Saki's workload was small.

"How do I get it to foam?"

"Well, I can't disclose that at this time."

What are the ingredients?

A special liquid. I can't disclose that either.

Is the Maggi Polyethylene process also available at ......?

No, we have a special plant for that. No, we have a special plant for that, but it is too big to bring here.

There was some back and forth, but the event was generally well attended.

"Saki, you have done a very good job.

"Ah, Mr. Degas."

The Minister of Magical Arts and Technology, Mr. Degaus, also came to the conference and praised Saki's presentation.

But...

"You will not participate this year, Mr. Toa?

Saki nodded regretfully.

"Yes. My ...... father is traveling around now, saying that he has something he really wants to do."

"Well, that's just like Toa."

Degauze smiled and walked away.

* * * * * * * * * * * * * * *

Saki sighed with relief in the waiting room as the third day went off without a hitch.

The fourth and final day of the competition was the review and awards, so Saki's work was now done. Whether or not she would receive an award was not so important to her.

"Ahhhh, it's over!

"Good job, Saki!"

Then came Goose.

"Here's something for you. It's the special Persian juice from Horai Island."

"Thank you for the ......, Goose."

Saki, who had been exhausted, felt a little better after drinking the cold juice.

"Did Goose come today?"

"No, he was here yesterday afternoon. I saw Saki's booth and it was crowded with people, so I decided not to come.

Goose laughed, "I know what you do," he said.

"So I tried to come here yesterday after the meeting was closed, but I was told that only authorized personnel were allowed to enter.

"Oh, I didn't know that. I almost thought you were a heartless man.

Saki laughed jokingly.

"Ha, sorry about that. I told him I was done for the day and that I would help him clean up, and he let me through.

"So that's how it is. That's no wonder.

So where's all the stuff?

"Gin loaned me a craftsman151, craftsman152 and he's already done it.

"Well, shall we go get something good to eat?"

"Okay, great. Goose bought it, didn't he?

Saki took Goose's arm and stood up.

"I'm sure Saki has more money than you. ...... Well, never mind. I'm going to launch a little early.

"I'll treat you to dinner."

And the two of them walked into the town of Trom in the gathering dusk.
