"So, do you have any more suggestions?"

The old man took over the explanation. This time, he talked about some simple things.

First of all, the plants to be grown in the plant factory should be strong, fast-growing, and rich in nutrients, and the following plants were suggested as candidates: soybean, sweet potato, buckwheat, and strawberries.

Next, as for the boats, it is better to prepare several boats that can be used for various purposes than to prepare each boat for a different purpose.

Furthermore, it is proposed that a super-small boat for reconnaissance is necessary.

And as a backup power source, as many magi crystals (magi crystals) and aethenols as possible should be loaded.

Finally, he concluded by asking them to fly with a support fleet instead of just <.

"I see."

This was something that made sense to Jin. All of these contents were motivating for Jin.

It is much better than a drum-type space suit.

Erza glanced at Jin's profile and showed an ambiguous expression, like a wry smile or a smirk.

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

In the end, Jin agreed to all of the old men's proposals.

We will think about the fleet after <> is completely successful.

Instead, we have decided to build several 10-meter class spaceships of the same type as <> to support the fleet.

However, in case of emergency, we will modify the spacecraft to accommodate human passengers inside. In other words, they can be used as escape boats.

In addition, we have decided to build several 2.5-meter class spaceships for reconnaissance purposes.

The old man will be in charge of this.

"All right, I'll review the on-board boats.

Jin finished his lunch a little early and started to work on the all-purpose carrier first.

"Brother Jin, what's your plan?

Erza is ready to be his assistant.

"Well, first of all, let's enumerate what kind of situations we have in mind.

"Hmm..."

"The world of Ars. There's gravity, oxygen, the usual.

Airplanes, cars, quadrupeds. Everything is okay.

The ocean, water everywhere.

"A ship or an airplane. A submarine would be good.

Reiko joins us.

A place with a vacuum and little gravity.

A small, airtight spaceship, maybe.

Anne comes in and lends her wisdom.

"A place with dense vegetation, like a rainforest."

"It's difficult. There would be too many obstacles to fly over, so maybe a heavy car or a quadruped."

This is Lol.

"A world covered in ice."

"A plane or a quadruped."

And Lefa. The point is, they're all in.

"Well, airplanes are very versatile, aren't they?"

"Of course they are. It's also fast and convenient.

Erza agrees with Jin's mutterings.

"However, there is a disadvantage of overlooking a fast plane, isn't there?

Anne points out. Jin nodded his head in agreement.

"The jungle would be the most difficult case. Even a small armored vehicle or a quadruped would have a hard time.

"In that case, I guess we'll have to do some mowing."

"I guess so. ......"

Jin had to agree with Refa's statement.

"So, should we give small armored vehicles or quadrupedal vehicles the ability to fly?"

Rolle's statement is right on the mark. Jin also thought that this was the right direction.

"The one that flies is a force field generator, so we can think of it as traveling on land and on water or underwater.

In space, the pressure difference is only one atmospheric pressure, but in water, the pressure difference increases by one atmospheric pressure per 10 meters of depth.

In other words, the submarine is more robust than the spaceship when it comes to pressure differences.

"Well, I don't know, I don't have a coherent direction. ......"

The all-purpose or general-purpose is often more difficult to use than the dedicated.

"...... planes walk or cars fly?"

"Oh, that's easy to understand."

Erza's expression was amusing, so Jin laughed and tried to follow the idea.

"Father, why don't you think about how often you use it?"

Reiko also came up with a useful suggestion.

"Yes. ...... the moon and the long-period planets to begin with. And ...... Hale. That's where it's at."

"I don't think there are dense forests on the moon."

Long-period planets are ...... unknown.

There are no dense forests on the planet Hale, or if there are, they are limited to a few areas.

Anne, Lol, and Leffa all share their thoughts. Jin was enjoying the situation.

"Then, we should start by thinking about growing legs on the plane.

"...... is kind of creepy."

Unusually, Elsa mixed it up.

"I guess so."

Since Elsa also said so, Jin thinks of a safe design first.

"......After all, we should fly a car. ......"

Jin imagines a flying car as seen in near-future comic books.

"The base car must have a futuristic design.

The idea of a classic car flying in the sky is also very appealing to the enthusiast, but Jin thinks that he should start with an orthodox design.

"Goshujin-sama, please consider the damage caused by cosmic rays and ultraviolet rays.

"Oh, that's right."

If Ann hadn't told me, I would have made the cockpit a transparent dome," Jin reflected.

"All covered with metal, with a magic screen on the outside. ......"

"I think that's a safe bet."

......, I don't have a choice.

As Jin, I know how helpless the human body is in space.

He proceeded with the design without any difficulty.

The result is a < in the shape of a flattened egg.

To put it more simply, it is shaped like the < of an apple PC.

It is covered with four layers of magi invar, mithril, soft magic resin, and 64 light silver, and flies with a force field generator.

And to top it all off, it has no tires or legs.

This is a barrier cushion car!

Father, what does that mean?

What does it mean, Brother Jin?

Reiko and Elsa tilted their heads, not understanding what it meant.

There is a type of car called an air car.

Officially, it is called an air cushion car. On modern Earth, it would be more commonly called a hovercraft.

Air is sucked in, and it is sprayed on the bottom of the car, and the pressure makes the car body float.

Jin's hovercraft used a <> instead of air to make the body float.
