Jin explains the purpose of his visit to everyone.
"I came here because I heard that a new invention had been made at the Goh Lab.

Eira was impressed.

Eira pointed to a balloon.
At first glance, it looks like an ordinary helium balloon. At first glance it appears to be an ordinary helium balloon. ......

Reiko and Hope recognized the special characteristics of the balloon.

"Oh, that's great. Yes, that balloon has enhanced buoyancy. Of course, it's not hydrogen."
"Really?"

Normally, balloons are filled with a lighter-than-air body.
According to Archimedes' principle, the buoyancy is obtained by multiplying <
Hydrogen is the lightest gas to fill the balloon, but it is flammable and has caused serious accidents on Earth in the past, so helium was used as the next best gas.

Eira was impressed, but with such an example in front of her eyes, Jin could have guessed it.
However, Eira and the others are indeed impressive for having made it this far on their own.

Regardless of that, the prototype balloon is now floating leisurely in the sky.
It looks like a golem.

"It is a lightweight golem developed for balloon piloting. It's designed for reaction time, eyesight, and low power."
"That's good, isn't it? It's a good idea to give it specialized performance depending on its use."

Jin also looked up at the balloon.
The propulsion system seems to be

"The next challenge is to apply it to airships, not balloons," he said.
"Is it a question of flight speed?"
That's what I meant.

So far, the speed of the balloon is about 20 km/h. That's about the speed of a bicycle.
The spherical shape of the air sac makes it difficult to fly fast because of the high air resistance, and it is also susceptible to the wind.

"Hmmm... ...... instead of making them long and thin, why don't you make them flat?"

The drag would be larger than that of a cigar shape, but smaller than that of a sphere shape.

Also, the pancake shape seems to be more stable.

Since these two functions are essential, the amount of free magic element (ether) consumed is low. Also, it does not fluctuate.
Therefore, the magic circle method can be used.
