All humanity's been made immortal.
But in exchange, Why-Man imprisoned us in stone.
And if we aren't happy with that exchange...
...we'll have to head to the moon to negotiate for ourselves.
Dr. Xeno joined the party!!
Are you serious?!
Are you sure we can work together with Xeno?!
So, Xeno-chan...
What exactly is this supremely suspicious machine?
I'm simply cooling some air.
So it's a cooler!
I'm extracting argon from the air.
Ar...gon?!
Gon
I wanna know how it works, now that I'm doing science.
Apply a current to argon gas packed inside a glass canister.
But electric zappy zaps don't go through the air.
Even I've learned that much.
Oh?
Dr. Suika, that's some elegant learning indeed.
Perhaps it'd be quicker to show you rather than explain.
You and Senku-chan really do act alike.
Ore deposit, huh?
Here-ish!
That signals an electric pulse going through the gas.
Rare metal deposits contain radioactive elements, after all.
Radioactive?
You mean it's...
A Geiger counter?!
That's freaky!
Nah, if anything, it'll keep us safe if it detects radiation.
There's always something dark about Xeno's science.
We used this technique to find mineral deposits in the 21st century.
Even a middle schooler could make one if they had some lighter fluid.
Ilmenite Ore
Molybdenite
Chrome Ore
Wait... What is this?
Pyrochlore Ore
Nickel Ore
Are these like those mystery ores you see in Monster Hunter and stuff?
They're actually the rare metals we need for the spaceship!
Nothing but treasures!
Holy crap, mining team!
Elegant indeed!
Literally a stone sanctuary!
Now all we need is...
Yeah, we're pulling it up right now.
My dear, dear Perseus!
I'm sorry you had to wait seven whole years!
Look at what's happened to you!
Damn, it's all red!
It's all rusted up, for sure.
It would have lost its ability to drain water
and sunk soon after it was abandoned.
I'll bring you back to life! I promise!
What are you doing?!
Recycling iron!
Iron's the one thing you can't get in this part of South America.
Sucks.
This way, we can upgrade it into a ridiculously souped-up New Perseus.
Huh? We can?
A new material made by merging metal and metal with science.
It's the superalloy, and it's all we need!
Superalloy
Here we go! We're gonna make a ton of superalloy!
You're starting to figure out how to work Kaseki-chan.
Throw the chrome ore into the iron.
We're throwing Chrome in?!
Gahhh!
Yes.
Combined with the power of chrome,
with the diverse strengths of many, it'll become even stronger.
That, too, is a tenet of science.
No rust, no corrosion. An invincible superalloy. Here we go!
Stainless Steel Acquired!!
So with this stainless superalloy...
What can we make?
With stainless, we can at last...
At last?
Stainless
...make canned food!
Lame!
We're in a world of all-you-can-mine high-quality rare metals.
Add in some zirconium and tantalum,
and we can make some fantastically elegant cans
that won't rot, even after 3,700 years.
In the old world, they would have cost us, like, a million yen each.
A million?!
Also...
Stainless
I see.
With stainless, we can enrich our dining tables
and bring everyone back from petrification all around the world.
Hang on, that may be true, but...
aren't we using it for rockets and ships and stuff?
There's still a crap ton of materials we're going to need for that moon rocket
scattered all over the planet.
Correct!
We'll need to make a new ship and gather them
all from around the world as quickly as we can.
Why don't we split up into teams?
I'll work on the rocket engine.
Senku, you work on the upgraded New Perseus.
Yeah.
We've got better things to do than
be two happy-go-lucky scientists holding hands.
First off, this stainless we're making right now is Level 1.
If we're to confront Why-Man on the moon, we'll need a superior superalloy.
What the heck is this?
The smell coming from it is insane.
It turns nickel into gas, purifying it.
It's essentially a superalloy level-up facility.
But the gas that comes out is absolutely toxic.
A mask does nothing.
It is absorbed through the skin, leading to swift death.
And in order to ensure that it doesn't leak out,
we first made Level 1 stainless.
That's terrifying! Holy smokes.
In order to build our road map of science to go into space,
we have no choice but to harness toxicity.
Not all would approve.
So I'll take on the dirty work myself.
As the science user of darkness.
That way, I can ignore all the low-minded noise
and elevate science without restraint.
Senku can, as the science user of light, lead the others into the future.
Elegant indeed.
The right man for the right job.
Two different people coming together to become the most powerful.
Like a superalloy!
Superalloy City Founded!!
All of humanity has finally come together.
Let's fight fantasy with science, shall we?
The scientist of darkness and the scientist of light, together.
Crap! Hang on, dang it!
Where are we going to get fuel for the ship?
There's seriously no petroleum around here in the Amazon.
Does that mean we're starting with sailing ships again?
This is the futuristic New Perseus we're talking about.
We're making it go with future energy.
Future energy?
Yeah, by which I mean...
food waste!
It's what we call biofuel.
Any kind of organic waste will do!
Leaves, leftover food, poop, use it all!
And we gather all the gas that comes off it when it rots!
Poop!
Not poop again!
Senku-chan, don't you need to collect the gas
that's coming out of all this organic waste?
Yeah. Which is why...
we're making a tank to hold all the gas!
Ah, I think I've seen those at, like, industrial facilities.
It must be crazy hard to make those perfect spheres.
All done!
That's it?!
It's not even that spherical!
It doesn't need to be perfect.
Fill it with water and blow it up in the middle, and...
See? Now it's a sphere.
That's it?!
That's how they make those round tanks?!
It's true.
And what's this now, Xeno-chan?
We need a lot more heat than those furnaces to make superalloys.
We're melting them down with electricity, like induction cooktops.
Why are these wires shaped like hoses?
They're water-cooled.
Otherwise, the wires themselves will overheat and melt.
And this is... what, Senku-chan?
This is the Fischer-Tropsch process.
Not that you'd know what that is.
Nope, I don't.
It's a trick that the gas-starved German army came up with.
You know, that thing that turns organic waste gas into liquid fuel.
No, I still don't get it.
Nickel
Chrome
Molybdenum
Iron
Titanium
Niobium
Now, we mix together all these metals that we extracted from various rocks,
and we have this indestructible metal that makes the rocket engine possible.
It's resistant to heat, cold, oxidation, corrosion, and creep.
Say what?
It's the superalloy of all superalloys.
So it's insanely strong, huh?
That's insane.
We put it all together over half a year using science.
All this was just rocks that were lying around in the ground.
March
April
May
How's the engine?
Not a hitch.
And what about your liquid fuel?
I suppose I needn't ask.
All good.
How about some show-and-tell?
Rocket Engine (Level 1) Acquired!!
It's a rocket jet!
No, it's a gas turbine engine.
To fly a spaceship, we'll need a lot more.
We'll need a Level 99 engine.
That said, we're well on our way to confronting Why-Man himself.
It's the first step in our lunar journey.
After a brief moment of cooperation several thousand years in the making...
Now, Senku, you and I will be taking different paths again beginning tomorrow.
Yeah, we sure will.
We're splitting into three teams.
Why?!
It'd be nice to take a break in our newly established city.
But the whole world's still petrified.
Japan, the treasure island, and Corn City, too.
He's right!
We're coming, Yuzuriha!
We'll be splitting into...
The team that remains in Superalloy City.
This is the team that'll be moving science forward,
collecting ores and evolving the rocket engine.
The team that will return to Corn City.
This is the team that'll work with everyone in the US headquarters
and get corn production in gear to set up the revival of the human species.
No way!
I don't want to be away from Senku!
Let me teach you a secret.
Senku-chan seems to like capable women.
I'm totally competent, of course.
And the team that'll be moving on to a new city.
This team will be crossing the Atlantic and traveling all across the world,
gathering materials for the spaceship until they arrive in Japan.
They're breaking ground into the future.
Yikes.
How many years is it going to take to get to Japan?
Not to worry.
You know that rocket engine we all broke our backs making?
You didn't think that was only for the spaceship, did you?
New Perseus Acquired!!
It's so fast!
I was hoping for a heartfelt goodbye, but they're already out of sight!
I mean, we'll be in touch with them every day via radio anyway.
The old Perseus was 300 horsepower with a maximum speed of four knots.
The future superalloy engine is 10,000 horsepower, 20 knots!
It took 40 days to cross the Pacific, did it not?
On the New Perseus, we'll make it across the Atlantic in a mere week!
This is tremendous.
It's hard to believe this is a ship.
We're going about five times faster.
Damn... With an engine like this one,
we might actually make it all the way to the moon.
They were just rocks!
Chrome, are those tears?
What's wrong?
I don't know.
I don't know, but...
One week until the Atlantic is crossed
The breeze on the deck is so cool and comfy.
It's actually not that cool...
It's so hot, I'm going to melt.
The sun is right above us.
We're in the middle of the Atlantic, right near the Equator.
Retreat! Retreat!
It's so cold!
My sweat's clearing up so fast, it's almost freezing.
Oh, man!
A.C. Acquired!!
We've always had a fridge.
It's the same thing.
The New Perseus's engine let us electrify the entire ship.
Wow, wow, wow!
We're in first class!
Science for the win!
It's like we've come right back to modern civilization.
Especially now that the Senku-chan and Xeno-chan team
has doubled their horsepower.
Partially, at least.
We aren't quite there yet, though.
For example...
We're going to be
intricately connected all throughout the world as we delegate tasks.
But it's not like we have satellite communications,
so we can't make voice calls over long distances.
We'll be limited to Morse code contact.
And so we're going to need everyone to practice Morse code.
Us, too?
I need to start with learning to write.
I can teach you how to write!
Come to think of it...
The first time Why-Man showed up,
he noticed us because we blasted a stupid amount of radio waves, right?
Doesn't that mean we're going to get found out by Why-Man again,
using so much radio?
He'll know the humans are on the move.
Ukyo!
Yeah, I heard it, too.
That signal...
It came from the moon!
Oh, crap!
Why-Man's sending us a message!
Yeah, since a while ago.
Gah!
We've been sending out radio signals for a while.
True...
He's been why-why-ing every time.
It's long been established that Why-Man responds to radio signals.
We could have resorted to guerrilla warfare,
using no radio signals whatsoever.
But we've been using induction cookers and stuff anyway.
We're leaking radio waves everywhere.
There's no separating science and modern technology from radio waves.
That's not it.
Now that I've learned Morse code, I can tell you...
The letters he's sending aren't Ws, Hs, or Ys.
I don't know what he's saying because it's in English, but...
D? O...
Y O U...
Do you wanna die?
