Original subtitles

Perhaps, on the other side of the ocean, there's another group of survivors like us.

Could just be a distress signal, right?

Some ship out at sea that happened to pick up our signal.

Sure, but then they'd be sending "SOS" or "Hello".

In that situation, we'd be the ones asking "Why?".

Well, there's no point sitting around worrying about it.

All we can do is leave Senku and the others to do their thing while we do ours.

Now let's get to work, guys!

I couldn't agree more, Taiju-sama.

Indeed.

It's never good to have too many cooks in the kitchen.

We should leave the strategizing to those in the war room.

They're the ones who heard it firsthand, after all.

Plus, they're the five sharpest minds in the Kingdom.

Our wise commanders.

Well, except for Chrome, I guess.

He's got the smarts, but he's way too hot-headed.

I am not!

This is exactly what I mean.

Should we be worried?

Let's make sure we're all on the same page about everything that's happened.

One day, without warning, a beam of light washed over the planet

and turned all of humanity into stone.

Of course, humanity has never possessed technology with such powers.

3,700 years passed, and eventually Senku was able to revive himself.

And now, we're all here in the present day.

And we suspect this Why-Man is behind the whole thing, right?

Are we calling him "Why-Man" now?

There's no way this guy just survived for 3,700 years, though.

That is, unless...

he petrified himself alongside the rest of humanity.

Wait, hang on just a sec!

Look, I know I lost my temper earlier, but hear me out.

Why are we just assuming this Why-Man is the one pulling the strings?

What if he's actually on our side?

Sure, he very well could be.

But we'd only be wasting time considering that possibility.

We've just gotta assume the worst.

And maybe, if we get lucky, we'll have overprepared.

At the very least,

he certainly doesn't seem very friendly.

I mean...

Are you the mastermind?

He completely ignored Senku-chan's provocation.

And afterwards, he stopped sending "Why?" entirely, and has been radio silent ever since.

So we've got a mysterious, invisible entity who could be anywhere and attack us at any time.

We're really in a pinch here.

Bingo!

You gave me an idea that'll make this easy.

We're gonna make this invisible entity visible...

using the eyes of science.

An erlenmeyer flask?

We're gonna see the enemy through this?

Nah, there's no way.

Yep, pretty much.

I was right?!

I've got a job for you, power team.

Remember this sphalerite ore that we collected from Chrome's cave of treasures?

Now that you mention it, I do remember gathering that stuff.

Basically, I just need you to crush—

Like a freakin' jackhammer!

...it up a bit.

Dissolve it in water, throw it in the flask, and wait for it to stick to the glass.

Now you've got fluorescent paint!

I can take it from here.

We're basically just turning the flask into a big vacuum tube, right?

Couldn't be easier!

I have absolutely no idea what this is supposed to be.

Maybe it'll make more sense once we turn it on!

Boop.

It's the same concept as a vacuum tube.

We heat up a cathode, causing it to eject electrons.

Then, we use electrodes to accelerate them.

Electron beam!

They slam into the fluorescent paint at the bottom of the flask, and a dot lights up.

Now we have ourselves a display.

I was already prepping everything to make it since we need one for our GPS.

Easy peasy, right?

This is a display?

It just looks like a dot to me.

Ya think Senku's finally snapped?

Maybe all this mad science is finally getting to him.

I know it just looks like a dot right now. But by nudging it around, we'll get our display.

We have it scan at a precise rate, from left to right, then top to bottom.

Do that across the entire screen, and you've got your image.

That's how the good ol' CRT TV did it.

But how do we make the beam move at such a precise speed?

For that, we need to draw out the power of a magic stone: the crystal.

Now he's saying we're gonna use a crystal ball to find the enemy?

My dude has definitely snapped.

Nah, you haven't lost me quite yet.

Crystals really do have magical powers.

Huh? This is still science we're talking about, right?

Oh yeah, it's ten billion percent science.

Shoot some voltage through this crystal plate, and it begins to vibrate.

At an insanely precise frequency, to boot.

Like pure magic, those vibrations give us a beautifully precise sine wave of electrical current.

Apply that current to a pair of metal plates, ram our electron beam through...

Curve!

...and now it forms a perfect curve.

The dot spread apart!

It's making a perfectly straight line!

I'm not really sure how it works, but I guess we've got a crystal TV, right?

If there's one thing I am sure about, it's that crystals are badass!

To think a single stone could hold such power.

Mother Nature truly is magical.

Yeah.

And we'll continue to gratefully make use of Her magic.

That's what science is all about.

We've got the horizontal curve, so now we just need the vertical one.

For that, we connect our radio antenna to the top-bottom pair of plates.

Ah, now I get it...

I see what you made!

I'm a sonar operator, darn it! I should've figured this out way sooner!

Making the invisible visible...

using the eyes of science.

A radar!

By changing the input from our radio antenna to a microphone,

we get an underwater sonar.

This should be right up your alley, Ukyo.

GPS, radar, sonar...

This really is shaping up to be a vessel of science.

It's like I always say.

Humanity's strongest weapon is information.

We'll flush you out, Why-Man.

It doesn't matter whether you're on land, up in the sky, or under the water.

There's only one possible reason your first question to us would be "Why?", after all.

You must have something to do with the petrification.

So this squiggly line shows us what's under the surface of the water, right?

And this last part is the seafloor?

So then, what does this zig-zag in the middle mean?

Senku, Ukyo!

There's something in the water!

A whole lot of something!

Nice spot, Chrome!

This was half the reason I wanted sonar to begin with.

We're going on a stupid-long voyage to the other side of the planet.

Naturally, we're gonna need to pick up some fresh food along the way.

We can use it to find fish!

Talk about a big haul!

Now that we have radar and sonar guiding our way,

we can travel to the other side of the planet

and track down the mysterious Why-Man!

Yeah, if you think about it, we should really be thanking Why-Man.

Before he came along, we had no idea what we were even looking for.

Now that he's gone and painted a target on his back,

we're one step closer to solving the mystery of the petrification.

You sure are enjoying this, aren't you?

Even when the enemy could be lurking around any corner, huh?

If Why-Man meant for that creepy message to be a threat,

it's almost funny how hard it backfired.

It was never going to work on Senku.

Yeah, you're right.

That's just the kind of person he is.

I've never seen so many fish in one place!

Between my bread and the fish we find using radar, we shall not lack food on our voyage.

Using this small device, we can see through the ocean and spot fish.

Radar and sonar truly are incredible.

Got that right.

Whether it be the murky ocean or the cloudy skies, this will let us see through anything.

See through...

...anything?

We can see through anything?

Now, just theoretically of course, but does that include clothes?

For instance, a girls'...

Uh, actually, I misspoke.

I'm really just interested in the science.

Could you be any more sleazy?

You really are the worst, dude.

X-rays can kinda do that, I guess.

You'd see through more than just their clothes, though.

Radar can see through anything, huh?

Give me a break, guys!

Chrome's thinking the exact same thing!

No way!

When Chrome's got that look, it's because he's thinking up some new project.

Don't ask me what, though.

Any feedback on the radar? You're the expert here.

My biggest concern is the power draw.

Batteries alone aren't going to cut it.

We've got that covered.

We're gonna pack the ship with a bunch of huge-ass engines

that can generate all the power we need.

Another nigh-impossible task? Don't threaten me with a good time!

Once the engines are taken care of, we'll be ready to set sail, right?

Yeah.

There's just one tiny problem.

We're talking about producing industrial-scale steel machines here.

These aren't just some rinky-dink creations you whip up in a lab.

We're venturing into the realm of true manufacturing.

Meaning we're gonna need a comical amount of steel and oil.

We're running out of iron sand.

There's only so much we can scoop out of the river.

Radar can see through anything, huh?

The sky, the sea...

Well, why not the land too?

We could find iron deposits or whatever other resources we need.

Which thing releases those electro-whatchamachallit waves, again?

It's this windy coil, right?

Just gotta hook it up to the radar screen.

Well, here goes nothing.

Let's test it by putting it up to the metal.

Where'd Chrome run off to?

He darted off at top speed looking real happy.

He was like, "Oh, crap! This could work!" or something like that...

This place takes me back.

And so the god of lightning descends.

It's the barren mountain where we harnessed lightning with Senku and Kohaku!

I rigged the radar to react to this iron.

And this is where I found it!

Check out this crazy rock I happened to find on some barren mountain!

I'm sure of it.

It was a long time ago, but this is definitely the spot.

There's gotta be more around here!

It moved.

It moved a tiny bit, didn't it?!

It definitely did!

All right, let's do this!

Underground Radar: Bamboo Edition!

Man, this is tricky, but it's so damn fun!

It feels like I'm finally on a real treasure hunt!

Let's go!

Senku!

You've made yourself a bonafide metal detector.

Though, since it's electromagnetic, I guess it's really an underground radar.

The coil's magnetized.

So when you put it near a magnetic ore, it spits out a crap-ton of induced current.

The resource king has done it once again, using the power of science and his own two feet.

He's found a full-fledged iron deposit!

Look at him, being all smug.

Don't give him too much praise, or it'll go straight to his head.

You can relax.

I'm not gonna let it go to my head.

It's just, like, I had this idea in my head, right?

So I ran an experiment, and then the science was dead-on!

Man, it just feels so cool!

Yeah, I know the feeling.

It's a rare one, though, so don't take it for granted.

This really is quite the haul.

Like I said, we're entering the Industrial Age.

We're gonna need way more resources than we did before.

Goddamn!

This is completely impossible, man!

Oh, right.

I hadn't even considered how we're gonna get all this stuff back.

It's all crazy heavy.

You're not wrong.

It's hard enough getting it out of the cave, and that's only the beginning.

We have to navigate around mountains and cross the ocean, too.

Now that the Kingdom has a hundred people, we've got the manpower to sort this out.

But it's gonna take all our strength to pull it off.

Senku!

Is something like this what you had in mind?

Yeah.

They're perfect. Ten billion points to you.

Kaseki, I'm trusting you to handle things here.

We'll take care of this, Chrome.

The crafts team's gonna make quick work of this cave!

Huh?

All right, let's get things rolling on the work outside, too.

Senku, what are you talking about?

What is the Kingdom doing, exactly?

We're making a crazy-fancy distribution network.

E-Er...

O-O-O-Once they get things set u-up over at the cave,

I'm s-s-s-sure we can handle the land leg of the d-d-d-delivery route, no sweat.

The road is just a tad rough, though.

Pain.

Wh-When did we start paving roads?!

We're going from stone world to concrete jungle pretty quickly, huh?

What can I say? Once you have oil, the world changes in the blink of an eye.

That said, concrete is 90% gravel, anyway.

For real?!

I guess, since it's all goopy and mud-like, I just assumed it was mostly oil.

Same, man.

That would be such a waste of oil, ya lovable oaf.

It's a mix of oil byproduct and gravel, right?

Talk about bang for your buck.

The byproduct of refining oil you mentioned earlier...

That's called asphalt.

Mix it with gravel, spread it out on the ground, and then...

Go...

...rilla!

You just gotta beat the living hell out of it!

Gorilla! Gori-Gori-Gori!

The road is literally growing before our eyes.

Is this the power of science? Or just the power of primal strength?

Who needs a road roller when you've got the power team, right?

Making a huge network of roads would be way too much work.

We're just gonna pave over the shortest route to the river.

Works perfectly for us, and is much appreciated!

Now that you've managed to bring the shipment down to the river...

We, the people of the water, will take things from here!

You hardly even rowed on the way over here, you piece of crap!

Transporting stuff by water...

is a lot more efficient than by land.

You can say that again!

Japan's narrow shape has always given it an advantage when it comes to logistics.

Speaking of which...

The Nanami Conglomerate, king of logistics, started out by shipping cargo during the Edo Period!

And that's how your ancestors became filthy rich, huh?

Damn straight!

There's just one thing left.

We've gotta figure out how to carry that painfully heavy iron up this horribly bumpy hill.

Now that our society has entered the Industrial Age,

our ambitions have grown beyond what Senku can do alone.

If he is to be an effective leader, he must learn how to command our people.

In other words, the art of empire-building.

From a young age, I was trained in this art by the Nanami Conglomerate.

I was told one must repress their emotions

and renounce all material desire.

But do you really think I bought into that load of crap?

None of that matters at all!

What people really want is a leader who knows how to have fun!

Somebody who relishes in the world around them...

That's the kind of leader who can win hearts and minds!

In that case, our Kingdom of Science...

has absolutely nothing to worry about.

When you're mining and crafting, there's only one proper way to get around...

Minecarts!

Holy shit, this is so fun!

I don't give a damn if you're the mastermind behind the petrification.

That ain't gonna stop us, Why-Man!

We'll collect an insane amount of resources

and chase you to the ends of the earth!

Our badass distribution network is finally ready for primetime!
