21-03 Undersea exploration

On December 19th, Jen and Elsa were there for breakfast too, coming to the dock in Tatsumi Bay.

Finally, we're going to get on a submarine and head for a submarine exploration.

"Brother Jin, what's the name of this ship?

Elsa notices just before.

"Um, well. I'd like an official name. The submarine stays the same, and the U-boat doesn't work..."

Still bothering Jen.

"Hmm...... how about 'Shachi'?

"... I think it's good"

"All right, let's make it the right color"

The first layer of the outer plate is 64 light silver, so you can change the color freely. Jen was quick and finished black and white (in fact matte silver white).

"Elsa, name him."

"What, me!?

"Even Bernstein was Elsa."

"... yeah"

The clothes remain intact, but Elsa corrects her posture, points her at the new submarine and declares.

"I name thee Shachi."

Titty, and Reiko, Edgar, and Jen applauded.

Come on, let's go.

"Mmm."

Jen takes Elsa's hand and gets in from the hatch on the side to 'Shachi'. Reiko and Edgar also continued.

The entrance and exit are double, and when the outer hatch is tightly closed, the inner hatch becomes open.

It's the same idea as an airlock on a spaceship.

"Reiko, can I ask you to steer?

"Yes, Father. I'll take care of it!

The submarine, like the plane, is three-dimensional manoeuvre... I don't do a lot of kirimi or repetition... so if I'm not used to it, I get confused.

This time, Jen honestly decided to leave the manoeuvring to Reiko, who is used to it on the test voyage. Reiko is also entrusted with joy.

If the level of control nucleus (control core) for automatic manoeuvre has increased sufficiently, Jen intends to maneuver and see for himself.

"Okay, I'll go"

The gate of the dock opens and connects to the sea. First I used a water magic propeller (Aquathruster) and "Shachi" started moving slowly.

"Oh, it's pretty comfortable"

It is also a fresh view that the gaze is quite close to the sea level.

While doing so, 'Shachi' left Tatsumi Bay.

"Okay, I'll dive in"

Reiko activates the Gravity Control Magic Device. As a result, the "chachi", slightly heavier than the water, slowly sank beneath the water.

"We don't need it anymore when we sail underwater."

The small fins attached on both sides… the main wing and the fins attached on the rear… the action of the tail allows hydrodynamic downforce to occur during the voyage, so it does not have to be forced to be heavy.

"First, it's a normal voyage."

'Chachi' advances with a water magic propeller (Aquathruster).

"What's happening to securing free magic hormone (ether) in the water?

Second, Elsa uttered the question that came to her mind.

"Yes, Mr. Elsa. You're no different than in the air."

Jen thinks when he hears that.

"Um, I guess it doesn't affect things like the atmosphere or the water because the grains of free magic (ether) are small. … which means there could be enough free magic (ether) in the vacuum"

It was Reiko's voice that broke those thoughts.

"So here's the Force Generator promotion."

"Oh, wow."

One beat late, the floating sensation strikes. The Force Generator is an entire ship… it works directly on the molecules of everything, including the crew, so you don't feel acceleration.

"is, fast"

Outside the windows is a blue sea, but it is so transparent that it can be seen well to the bottom of the sea that it passes backwards with great momentum.

It's about 300 kilometers an hour.

Old man lets me know.

"It's not safe for your fathers to ride any more."

Says Reiko with a look of sorry.

In fact, 3600 km/h, Mach 3 in the air seems to be the upper limit for wind avoidance, water avoidance junction generation speed, so in theory we should be able to give 3600 km/h even in the water.

"In case you think about it, it's manned and we can't recommend that speed."

And the old man stabbed me with a nail, too.

"I get it. So, what's the maximum depth of submarine?

The maximum depth of submarines on Earth today is about 500-600 meters. Russian Sierra type nuclear submarines are said to be around 750 metres (no clear data available because they are military).

So much so that some experts do not bother to look at the critical limits in the first place because when the pressure resistance exceeds the limits, they conceive of the risk of crushing them all at once.

"I think we can go 1,000 meters..."

"All right, let me sink slowly. I monitor hull distortion with engineering magic. As soon as we're in danger, we're gonna surface on the Force Generator."

"Is that okay?

"Yeah, I don't think there's much danger in that way"

As for Jen, he wanted to know the maximum depth of submarine exploration.

"Elsa, just in case you're ready for the transfer gate."

"Mmm. Copy that."

Thus, 'Shachi' sinks slowly.

In fact, there is a so-called 'trench' that depresses deeply at once in the vicinity around Penglai, around the end of a loose slope about 200 metres deep in water called 'continental shelf' in topography.

It was thought that there were about 1500 meters of depth around Jens right now.

Sonar is used to calculate the depth by pulling the distance from the current position to the bottom of the sea from the depth measured at sea level.

"... depth 500... 550... 600"

It exceeded the submarine's depth of submarine on modern Earth.

"... 700... 750... 800"

It is already dark outside. Jen was concentrating and monitoring the distortion of the ship's shell.

"... 800... 850... 900"

Still no problem level. The Giant Hundred Foot (Gigantopeder) crust is better than I thought.

"… 950… 1,000"

As a matter of fact, there's also a Mermaid unit waiting outside at your direction, old man. They also had a proven track record of withstanding 5,000 meters of water pressure and watched softly over 'Shachi'.

"1100... 1200..."

Illuminated by powerful lights, the seabed has emerged blurred.

And there's snowy white floats around the chachi. "Marine Snow." From around here, the relationship between the currents or the transparency has changed rapidly.

"... beautiful"

It was a view that made me forget when I was in a dangerous deep sea.

"... 1400, beneath the sea."

Under "Chachi" there was a 1,400 metre seabed. The distortion of the outer shell is still acceptable.

Jen exhaled in relief.

"Underground Exploration (Grand Search)"

It's the bottom of the ocean that I got to because of, so Jen I'll look into the bottom resources just in case.

"Oh?"

"Brother Jin, is something wrong?

"Oh.... there is light silver (light silver) and demonic crystal (Magi crystal). And many other metallic minerals in such shallow places."

You heard the words, too.

'That's good news, isn't it? Let's get ready for mining.'

"Yeah, I asked for it"

Besides it came with me to an unexpected harvest.

"Okay, I can't help it any more, it's surfacing"

For surfacing, use the force field generator Force Generator and return to sea level at once.

Since wind attribute-specific junctions, or junctions specific to airtightness, are applied in the hull, it is a great advantage that there is no risk of pressurization and decompression.

It has no effect on magic and keeps the barometric pressure constant.

From the deep sea, which was dark, when I went out to the bright sea, I relieved not only Elsa, but Jen.

"That's a huge success. This will make exploration of seabed resources easier."

That said, only one flaw came to light.

It's moisture. Jen, Elsa, the water vapor in the exhalation for two people makes the cabin look humid… If you mean solid, there was condensation everywhere.

It's a flaw that Reiko, who doesn't breathe, didn't know when she tested.

"This requires removing moisture with the water attribute magic 'condensation'..."

In contrast, the reuse of oxygen worked.

Rather than disassembling all the carbon dioxide in the air, Jen was able to construct a demonic formula (Magi formula) that determined the ratio of nitrogen to oxygen well.

In other words, you were right to take the control method of producing only the amount of oxygen you used.

The separated carbon is cemented as graphite.

"Shall I even make it with a pencil..."

It was Jen who considered it, for example.

gossip.

Once it surfaced and changed the air, Jen ran out again to enjoy the sea. Now at about 50 km/h.

"Ah, it's so sweet."

I see colorful fish swimming.

Jen and Elsa then enjoyed the view of the sea for a while.

Of course, it goes without saying that I applied moisture control after I left.
