At after Jin and the others had left.

"I learned a lot from your lecture the other day. ......"

Najaz Khan, a medical student from the Kingdom of Franz, is studying in his room.

"I heard that Deus ex Machina and Jin-san upgraded with medical knowledge, when are they going to start teaching us?"

She has been studying here as a mid-career student, recommended by Jin and Erza, but her grades were already in the upper middle of the range.

When she first entered the school, she could barely keep up with the lectures, but Erza had spotted her talent, and with her natural diligence, she had been able to improve rapidly.

"Naja, would you like to have dinner with me?"

"Oh, Polly, is it that time already?"

Pollyanna Pendleton, my roommate in the dormitory, called out to me.

She was from the Kingdom of Egelea, a quiet woman with semi-long brown hair and brown eyes. She calls Najas "Naja. Najas also calls her Polly.

"Naja is so studious," she said.

"Polly doesn't like books."

Najas knew that Polly had been in bed earlier reading a story.

"Well, to each his own, I guess."

Pollyanna said and hurried to the dining room.

"Ah, it's crowded..."

< was quite crowded as it was just around lunch time.

"Oh, but it seems to be moving fast.

"Indeed."

The cafeteria was run by <, whose operating efficiency had increased by 20% thanks to Makina's maintenance of all the machines.

The and are also lined up there.

"Any idea where the lab or ...... Naja will fit in?"

"Not yet. I've still got almost a year to go, so I've been thinking about it a lot.

Nadjas and Pollyanna are having this conversation as they stand side by side.

They are in the < and are studying a wide range of subjects.

Next spring, they will join a laboratory to study .

"But, you know, I heard that it's easier to get your wish if you show up early to the lab you want to go to and have them remember you."

"Is that so?"

"Especially if the lab is popular."

It is not always possible to get into the laboratory of your choice.

Each laboratory has its own quota, and if the number of applicants exceeds the quota, the applicants are selected by lottery and interviews.

The lottery is purely by lot, but in the case of interviews, it is said that the probability of getting your wish increases if you have a recommendation from a member of the laboratory .......

"I see. I guess I'd better decide by summer, then. ......?"

"About that time."

In the meantime, our turn came, and the two of us received a tray with our set menus on it and headed for an empty table.

* * * *

"Did you hear?

"Hear what?"

"I heard that there will be a facility called a wind tunnel in the near future."

<

"You're going to use wind magic to generate wind, right?"

"So we can test the resistance to the air, the weakness against wind, and so on.

"Depending on the size of the model, they can even put the actual aircraft in it."

That would be great."

I don't know where they get their information from, but they certainly have quick ears.

"Also, I heard that it can be used for training in high winds.

"That's the World Guard, isn't it?"

That's what I heard.

I heard that the deus ex machina who was here the other day suggested it.

No, no. <

"I didn't think so."

The cafeteria at lunchtime is a place of chatter.

Various topics of conversation are being exchanged.

The conversation is about many things.

What is it, Eira?

"It's a backpack that allows the Golem to fly.

< has made three quarter-sized small Golems with slightly different structures, and has been testing their performance.

Eira, Groma, and Cachea < made one of these golems, and Eira attached a backpack with circular wings to the golem.

It was a backpack like a school bag with circular wings at the end of arms that extended diagonally upward from the backpack. In other words, it is like carrying a < on your back.

The angle of the arm is adjustable so that the circular wing is always horizontal.

"Okay, <>, give it a try."

"Yes, Eirasama."

As a side note, this <> is not a <>, which is said to be a spirit of the earth, but an ancient word (origin word) meaning <>.

This is from a book that Katya found in the library.

<> is the lightest of the three prototypes of <>.

This is because the parts of the magic resin (magirezin) that it uses that do not require power are foamed in order to reduce its weight.

The smaller size increases the muscle power compared to the body weight, and Jin had advised him to adjust the <> of the in order to balance the movement.

However, there was plenty of time to make adjustments since the prototypes were made in the laboratory, compared to the last time when there was no time to do so. So Eira and his team tried to structurally reduce the power of the muscular part of the robot.

<, the weight was also lightened, so it took time to make adjustments, and now the <> of the are being adjusted as well.

Even so, we were able to reduce its weight to less than half that of the small golem delivered to the <>.

"I didn't even put in a skeleton or core material."

The use of foam made it <.

"This <> could be used up to about one-tenth the size."

Including the prospect of miniaturizing the Golem, the <> decided that they could manage up to one-tenth of the size by themselves.

activated the blow floaters on his back.

"Okay, go slowly!"

And then .......

"Oh!　It floats, it floats!"

Slowly, 's feet leave the ground.

"Yes, yes!"

Eira celebrates.

< floats about 50 centimeters and then comes to rest.

"Okay, now try to move forward slowly.

"Yes, Eira-sama."

moves forward slowly, maintaining the height of 50 cm.

However, since his body is still standing, it is as if he is swimming standing up in the air.

"Well, success is success, but it's not what I expected."

< is completed.
