04x30 - Stone to Space

[bunniefuu]

W-- wait.
For real?

We need your brainpower, Sai.

We have to learn everything about rockets.

And that means we'll need all the help we can get with the ridiculously hard math it's gonna take.

Will you teach us math, please, Sai?

Teach you math, huh?

I mean, I've taught before.

It was kind of a side gig
to stay fed while I was busy coding.

But it's like learning a whole new language.

And you'll be starting at square one.

You'll have to take this seriously.

Oh, yeah.

We're serious as we can be.

The stakes couldn't be higher,
and there's not much time.

We gotta build our return-trip rocket
before the one-way rocket's ready

because there's no way we can have a happy ending

without
everyone here with us to celebrate our victory over Why-man!

God damn it!

I went all around the world so I wouldn't have to build
that freaking computer.

But this has gotta suck at least 10 times more!

So if I understand the situation correctly, we're using
these red rocks here

to build this new rocket vehicle thingy?

Yeah, we'll process the hell out of them

by following this road map here.

And at the end of our journey,

we'll have the raw materials ready for making our rocket.

It'll be super complicated and challenging.

And that's the stuff I live for.

Oh, so this must be why we grabbed up all
those firefly rocks in Spain.

We're in for more ega-may time-consuming work, huh?

But let me ask you, what's that about?

It says an absolute crap ton of stupid, powerful electricity.

Oh, yeah.

There's a reason some people like to call aluminum canned
electricity

because making it takes an absolute crap ton of power.

Take the bills they rang up making the aluminum
for the Apollo rocket.

It cost them over 3 billion yen in power alone.

Not wrong.

You would need a limitless supply.

And if we want that much power, the only way we could generate
such an immense amount--

Is using a hydroelectric dam.

That's why we're going to take all these red rocks with us,

shipping them out to a country that's perfect for hydropower.

Water power, right?

So what would be the best country for building our dam?

It's a place that we're all familiar with,

chock full of peaks and valleys and loaded up with rivers.

And the funny thing is,

we've got materials in HQ already set up.

It's been a while since we last set foot there,
but it still feels like home.

Japan.

All these new cities will be coming together.

We traveled all over the globe to gather
the best materials out there.

And now we're going to bring them home.

That's right.

The Stone World's moon rocket will be made in Japan.

It's been a long, worldwide resource hunt.

And since we're here, does that mean that we're wrapping it up?

Yep.

This will be the last stop on our city-building tour.

We'll have all we need after this.

For realsies?

Oh, why, konnichi-wowsers!

Hey, look.
I see some islands.

Heading just south of the equator.

We're in Indonesia!

Look at that stuff flow.

Come to mama.

We did collect quite a bit of it
in Central South America.

But there's a reason they call this place
the "home of rubber."

It makes me so happy I could cry.

We're gonna need all that we can carry.

Rubber City founded!!

What a long journey.

We left our home in Japan,

crossing the Pacific Ocean to explore the Americas.

We almost lost everything.

But through grit and determination,

we founded Corn City,

bringing people back to life every step of the way.

We built the city of superalloys,

the city of fluorite, the city of math and fuel,

then the city of aluminum.

And lastly, the city of rubber.

After all these years,

it's happening.

We're finally heading back to our homeland!

We'll be reunited with the ones we left behind.

All of humanity is coming together to achieve one goal,

probably for the first time.

One major milestone after another.

Yeah, we've united the entire world.

We'll get it done

build our return rocket
so we can all celebrate our victory over Why-man.

Yeah, we'll bring everyone together.

'Cause if we're gonna build a rocket that can take us to
the moon

then we gotta revive as many people as we can.

It'll take insane amounts of backbreaking labor
to pull this off.

You've never really been the overly sentimental type,
have you?

I wish we had a way to let them know,

to tell Ruri and all the others still petrified
that this hell's almost over.

The real hell comes when Senku puts them all to work.

Surely they'll at least want a souvenir or two
from our tour of the world.

And that's not wrong.

That was pretty much always the plan.

Oh, prezzy, for real?

You're the b*mb, taking care of your besties.

Yeah, no. If I had to guess, he's got
another scheme hiding up his sleeve.

There's always an ulterior motive if he's involved.

Oh, come on.

What have we done every place we've landed?

It's become our own tradition by now.

We always make it a point to whip up
some local cuisine ASAP.

If we want to power the bodies of the folks we're waking up,

what better fuel than soul food?

Oh, the nums.

Now that's the way to gas somebody up,

have them stuff their faces with all their faves.

And all this time,
I thought you just wanted some extra tasty meals.

I'll take all the tasty meals!

We're quite aware.

So in Japan, the soul food is--

Oh, hell yeah!

Man, how lucky is that?

Looks like we rolled up just in time for wild rice season.

Luck's got nothing to do with it.

Yeah, Senku would be pretty screwed if he had
to rely on his otten-ray luck.

He planned to be exactly in this spot in April all along,

to catch the rice harvest on the way back home.

Rice acquired!!

So this is all we get?

It's not really that much.

You know, nature does things its own way.

That's exactly why we're getting humans in the loop
by making a rice paddy.

We'll kick production into overdrive.

Go on ahead.

OK.

Next one, please.

It's coming right up.

Now you'll see, if you know the lengths
of the three sides of the triangle,

you can find out its area pretty easily.

And no matter how large the area may be,

keep breaking it up into triangles,

and you can calculate the size of any plot of land.

Just a little to your left.

Yeah.

OK, you guys can go ahead
and dig a channel straight to this spot.

Now it's our time to shine.

Yes, that's perfect.

Yay!

I know we need the supplies.

But are you sure we should start
planting crops this early?

Isn't it supposed to be every other year?

It's 10,000,000,000% the right move.

There are no nasty winters to stop us.

Oh, yeah.

We are south of the equator.

I still don't really understand.

What does not having a winter actually mean?

Try annual harvest.

No freeze means we can plant and harvest thrice a year,

all thanks to the power of science.

We just have to keep the soil in good shape

by rejuvenating it with fertilizer after each harvest.

Further proof that desire is indeed noble.

This looks familiar,

kind of like that junk we dug up before coming here.

Remember?

Those pink rock things Senku made us collect
from that weird island?

Yep.

Albatross droppings from Nauru.

They're phosphate rocks.

Phosphate rocks + Nitric acid + Plant ashes

Makes a powerful fertilizer.

[A LOT of] rice acquired!!

It couldn't have turned out better.

Even though it's indica rice,
this stuff's high in amylopectin.

So it's similar in composition to Japanese rice.

Splendor awaits.

That got me.

I don't know why.

The weird thing is, back in the 21st century,

I was never that big on rice ba*ls.

There can't be a better souvenir to take back with us.

Am I wrong?

But it's time to go back where our journey first started--

Japan!

Welcome back, Soyuz.

Senku.

Kohaku!

Good to see you, Amaryllis.

What the?

If we're on Treasure Island,
what's the deal with these rando Japanese uncles?

I happen to be an uncle from Japan.

Got a problem?

Ah, you must be that brainy Senku fella
I've heard so much about!

My kids told me all about your adventures.

Yo, what's up with the uncle army?

Those guys?

Deployed them on an extra special mission.

That just makes us more curious.

Soyuz, how are things progressing?

Oh, well, we were petrified quite a while,

so it's been slow going.

But reinforcements from the mainland were a major help.

It would seem that you've taken
to this island master business like an ish-fay to water.

Anyway,

I can't help but worry about Ruri
and the others back on the mainland.

There are so many people still waiting
to be revived over there.

Yeah, it's about time we pay them all a visit.

One more reason to book it back to Japan.

You must have given the folks we left behind some kind
of brutal mission.

Guess our team's not the only one
you're dragging through hell.

Well, good, 'cause I was starting to feel jealous
about all the free time they've got on their hands.

You know me better than that.

Whoa.



After traveling around that world--

It's our triumphant return to Japan!

You're safe.

Thank goodness.

Somehow you're still more worried about me than yourself.

You never change, do you?

Hold up!
Is there a reason she's freaky strong?

Am I issing-may something?

Makes sense to me. They're sisters

which basically means we're getting
a two-for-one special on guerrilla girls.

It's been a while since he got Kohaku-ed.

And here I thought there would be no casualties.

Chrome!

Whoa.
This is bad.

You were petrified this whole time.

Which means you and I are the same age now.

You've grown into a man since the last time I saw you.

How strange.

No freaking way.

Chrome caught the love bug,
for super realsies!

Heck, yeah.

Everyone in our village adores Ruri.

I mean, what's not to love?

That's so kind of you to say.

I really appreciate that.

It was foolish to believe he was finally going for it.

He may be a man, but he still has some growing up to do.

He's just a man-baby.

Always was. Always will be.

It's kind of too bad Chelsea didn't do her usual thing
where she keeps pressing the issue until they can't deny it.

I knew you were great, but this is something else.

When did you find the time to make this bad stone wall
to protect everyone?

This kept the statues from getting smashed up.

Otherwise, trees or other debris
could have been game over.

Oh, that's odd.

I've never set eyes on this wall before today.

Hey, Chalk, Sagara.

What do you know?

Suika's furry friends aren't human like us.

So that means they were never turned to stone
by Why-man's petrification beam.

Those fur ba*ls hung in there for 10 whole years.

So you made the wall.

Oh, wow.

You've been protecting the village for all this time.

Look at that.

Life kept moving.

You have families now.

Chalk, Sagara, goodbye.

I'm grateful you could awaken this many so swiftly,

but that's a lot of mouths to feed.

That's why we brought you a souvenir!

One bowl of food and they forget they don't live here.

But doesn't this kind of cheapen
that heartfelt goodbye they just had?

Say hello to our new villagers.

They're great for hunting and foraging.

I will be preparing a traditional dish
designed to nourish and strengthen us with rice.

Are you talking about rice ba*ls?

Something else entirely.

I plan to fuel our hearts and minds with Japanese soul food.

Sushi acquired!!

Now that we're all fat and happy,

let's kick that special mission into overdrive.

What mission?

The one you've been talking about
ever since Treasure Island?

You see, Senku left those of us who had stayed behind
with clear instructions,

a way for us to contribute from here in Japan
while you were off traveling the world.

You built an actual dam?

That means we've got hydroelectricity,

and boatloads more than enough to refine
the aluminum for our rocket!

And it's a ridiculously simple design.

We're literally just stopping water with concrete.

The same method was used from 1000 BC all the way
through the 21st century.

So that's where the pig and pup got the idea.

They learned from watching.

Now that's clever.

It looks like they put bamboo inside of the rocks.

It's bamboo concrete instead of ferro concrete.

A dam only has to withstand
whatever pressure the water is exerting.

In lieu of steel, it just needs a little bit of bamboo
to get the job done.

We crafted these parts across the globe,

gathered them

and brought them to Treasure Island,

a prime location that's nice and close to the equator.

We're really doing it, our special mission,

the rocket's launch site.

It's time to boldly go to the final frontier.

We'll face Why-man and stop him

with the strength of all humanity!

This is exhilarating.

Get excited.
