Wh-Wh-Who is this mysterious person talking to us?!
Maybe there's another group of survivors far beyond the ocean.
It's probably a distress signal, isn't it?
From a drifting vessel that happened to pick up our radio signal.
Their message would be "SOS" or "Hello," then.
Why are they spamming "Why?"
"Why" is what we want to know.
Kingdom of Science War Room
We won't find any answers just thinking about it.
Let's leave Senku's team to do their work and keep doing what we can on our end!
Time to get to work!
I absolutely agree, Taiju-sama.
Indeed.
Too many chefs spoil the broth.
We ought to leave the people in the meeting to decide what to do.
The five most clever people in the Kingdom of Science...
Our generals.
Wait, I'm not sure about Chrome.
He's smart, but he's too goofy.
I'm not goofy!
Case in point.
Now I'm worried.
Eyes of Science
Let's go over what's happened so far.
One day, a beam of light washed over the planet
and turned all of humanity into stone.
Of course, there was no such technology back in the day, either.
3,700 years had passed when Senku woke himself up from petrification.
I thought it was Why-Man who was behind it.
"Why-Man" is the name we're giving him, huh?
But there's no way he would have been alive for 3,700 years.
Unless...
he petrified himself with the rest of us.
Just a second.
I got pissed a second ago, too, but are we even sure Why-Man is an enemy?
Isn't there a chance he's on our side?
It's not that there isn't.
It's that there's no need to consider that possibility.
If he's on our side, we'll just have over-prepared. Big whoop.
Though, I'm sure they don't appreciate us, for sure.
I mean...
Are you the mastermind?
He ignored Senku's attempt to goad them into fessing up.
The "WHY" signal stopped, and he's been radio silent ever since.
An unidentified, unseen enemy who may be anywhere and could come from anywhere.
This is absolutely brutal.
That's it!
That makes things a lot simpler.
We're going to see the unseen...
with the eyes of science.
A conical flask?
We're going to see the enemy through this?
Nah, that can't be it.
We are.
I was right?!
I've got work for you, power team!
We're using this sphalerite that we mined out of Chrome's treasure cave of treasures.
Oh, yeah, I remember gathering those.
We're gonna bash the—
Powdered instantly!
...bash the hell out of them.
Dissolve it in water and throw it in the flask, and it'll stick to the glass.
Fluorescent paint!
And now we do the usual.
We're basically making a giant vacuum tube out of this conical flask!
Piece of cake!
I still have no idea what this is.
We might know if we turn it on.
Boop.
Just like with the vacuum tube,
we use electrodes to accelerate electrons emitted by heat...
Electron beam!
Slam them into the bottom of the flask, and a point at the bottom lights up.
And we have ourselves a display.
m 0 0 l 188 0 l 188 70 l 0 70
Cathode ray tubes acquired!!
I've been getting them ready so we could make a display for the GPS.
That was dead easy, huh?
This is a display?
It just looks like a dot.
Maybe Senku's finally lost it
from making so much complicated stuff.
We're nudging the beam around to turn the dot into an image.
We do it at a precise rate, from left to right, top to bottom.
That's how the cathode ray tube would make an image in the good ol' days.
How are we supposed to move the beam around so precisely?
We're calling upon the power of the crystal.
Now he's saying we're using a crystal ball to see the enemy.
I'm pretty sure he's wack.
Nah, I've still got my mind intact, just barely.
Crystals have legit magic powers.
Huh? We're talking science, right?
Ten billion percent science.
Apply voltage to a sheet of crystal, and it vibrates.
At a ridiculously precise tempo, too.
We shoot the magically clean wave of electricity coming from the two crystals'
incredibly precise vibrations at a sandwich of two sheets...
Curve!
And the electron beam passing between them makes a perfect curve.
The dot grew sideways!
It opened up and turned into a perfect line!
I guess that means we have a crystal TV?
Crystals are awesome! That much I get!
So much power from just one rock...
The laws of nature are so mystical!
Yeah.
And we gratefully ask it to let us use it for our purposes.
That's what science is about.
Now we just need to do the vertical curve.
All we have to do is connect the radio antenna to the top-bottom sandwich.
I see!
I recognize this!
I'm a sonar operator... I should have known from the beginning!
Seeing an unseen enemy...
With the eyes of science.
A radar!
We just have to swap the antenna out with a microphone,
and we have an underwater sonar.
Ukyo, this is your territory.
GPS, radar, sonar...
It's becoming an actual science vessel.
I told you.
Humanity's strongest weapon is information.
We're flushing you out, Why-Man.
Whether you're on land, in the sky, or in the water...
After all, the first thing you said when you saw us moving around was "Why?"
You have something to do with the petrification, don't you?
We can use the bendy shape to see inside the water, huh?
This last, flat part is the ocean floor, right?
So then, what's this zig-zag piece halfway across?
Senku! Ukyo!
There's something in the water!
A ton of them!
Nice, Chrome.
Half of the reason I wanted a sonar was for him.
It's going to be a stupid-long voyage to the other side of the planet.
We're going to need to find food locally.
We can use it as a fish finder, too.
Massive haul!
m 0 0 l 190 0 l 190 60 l 0 60
Radar and sonar acquired!!
We've gotten ourselves radar and sonar!
We're going to use the eyes of science to sprint to the opposite side of the planet
and find the mysterious enemy, Why-Man!
Yeah, we've got a lot to thank Why-Man for.
We didn't even know what we were looking for until now.
Thanks to him getting himself involved,
we can finally close in on the truth behind the petrification.
You sure are enjoying this.
All when the enemy could come for us, too.
If Why-Man's creepy message was meant to be a threat,
it's funny how much of an opposite effect it's had.
It doesn't work on Senku's type.
Yeah, you're right.
That's the kind of person Senku-chan is.
I've never seen so many fish!
With the fish finder and the bread, we've overcome the food issue aboard the ship.
Restaurant Francois
It's so strange...
We can catch all the fish we want if we look at the water through this.
Radar and sonar are incredible.
Yup.
Whether it's the sea at night or the sky through the clouds,
it'll see right through anything.
See right through...
...anything?
See through anything using radar?
Does that mean, and I'm just asking, what about clothes?
Like, girls'...
No, I mean, I'm just asking for science.
I'm interested in science now.
Unbelievably filthy.
Ginro, you...
I guess an X-ray would be the closest thing.
You'd see through more than just clothes, though.
See through anything with radar...
Oh, come on!
Chrome's thinking the same thing!
No way!
When Chrome's like that, he's coming up with some fun new project.
Not that I know what, exactly.
What are your thoughts as an expert in the field?
I think the biggest issue is the radar's output.
We're going to need more than batteries.
Don't worry.
We're going to pack the ship with a bunch of huge-ass engines
and generate a ton of power.
That'll be a pain in the butt to make!
I can't wait!
So are the engines the last step in building the ship?
Yeah.
But there's a bit of a problem.
Now that we're talking about huge-ass steel machines,
we're going to need a lot more than just a research lab.
We're venturing into industrial scale.
We're going to need a stupid amount of steel and oil.
We're running out of iron sand.
There's only so much we can scoop up from the river.
Restaurant Francois
See through everything using radar...
The sky, the sea...
In that case, couldn't we see through the dirt to find iron and whatever else?
What's the thing that releases radio waves or magnetic waves or whatever?
This windy coil thing...
This connects to the radar screen.
Whatever, let's give this a shot.
Let's try putting it close to the rocks.
Where has Chrome vanished to?
He darted off looking really happy.
He was like, "Oh, crap! This could work!"
This place takes me back.
And so the god of lightning descends.
It's the bald mountain
where Kohaku, Senku, and the rest of us captured lightning together!
This rock reacts to radar.
It's where magnetic metals are born!
This crazy rock that I happened to find on a bald mountain!
Try to remember...
Where did I find it when I walked here on foot?
That's where I'll find it, underground!
It moved.
It moved a tiny bit, didn't it?!
No, it definitely did!
All right, let's go!
Underground Radar Taketsutsu-o-matic!
Crap, this is hard, but it's so fun!
It feels like serious treasure hunting!
Yes!
Senku!
That's a metal detector.
Though, since it's electromagnetic, I guess you could call it an underground radar.
The coil interacts with magnetism.
Put it near magnetite, and it'll put out a crap-ton of induced current.
Resource King Chrome, you know what you found with your legs and science?
You found an iron deposit.
m 0 0 l 168 0 l 168 60 l 0 60
Mine acquired!!
Look at him, being all smug.
Don't give him too much praise. He'll never come off his high horse.
Relax.
I'm not being smug.
It's just that when you have some idea of how things work,
and the science turns out to be dead-on...
Crap, it's too fun!
Yeah, you're right.
Though it doesn't happen all that often.
This is quite the haul, though.
I told you, it's the beginning of the Industrial Age.
We're going to need orders of magnitude more resources.
Holy hell!
This is totally impossible!
Oh, right.
We hadn't thought about how we're going to carry it all the way back.
This stuff's so heavy.
You're right.
It's hard enough carrying it through this cave.
Oil Fields
Mines
Ishigami Village
Kingdom of Science
We're surrounded by mountains, and we need to cross the sea.
We have over a hundred people in our Kingdom of Science.
We're pooling all our strength to do it.
Senku!
Will this do?
Yeah.
Perfect. Ten billion points to you.
Kaseki, I'm leaving you in charge.
All right, Chrome, the crafts team's gonna make easy work of this cave!
Huh?
All right, let's move things forward outside, too.
Senku, what do you mean?
What is the kingdom doing, exactly?
We're creating a crazy-fancy distribution network.
E-Er...
If they can g-g-g-get that awesome cave sorted out,
w-w-we can hopefully make the land route b-b-b-by car!
This road's definitely a bit too rough, though.
Pain...
W-We're already at paved roads?!
We've gone from that primitive stone world to city building really fast.
Once we have oil, the world changes quickly.
Then again, asphalt is 90% gravel.
Seriously?!
I always thought they made it out of oil, with that thick black stuff.
I know, right?
We aren't wasting our oil like that, meathead.
Wasn't it waste fluid and gravel?
You can't get more bang for your buck than that.
The scum you get when you cook oil...
That's asphalt.
Spread it out over the ground with gravel, and...
Go...
...rilla!
Smack the heck out of it, and it's done!
Gorilla! Gori-Gori-Gori!
The road's getting built in the blink of an eye.
I don't know if this is science or primitive.
Who needs heavy machinery when you've got the power team?
We aren't covering the whole path in some mega-project.
Just the worst parts along the shortest route to the river.
This is more than good enough! Amazing!
Now that you've brought it to the river...
You can leave it to us, the people of the water!
You hardly even rowed the boat, Ginro!
Transporting stuff by water...
is a lot more efficient than by land.
It's always been that way.
Japan's logistics have always had the advantage of being a narrow island nation.
The Nanami Conglomerate is the king of shipping companies,
and we got our start as marine wholesalers in the Edo era!
And that's how your ancestors became mega-rich, huh?
Yup!
All that's left...
is getting this horribly bumpy hill ready to carry painfully heavy metal.
Once crafting reaches industry-scale, it's well beyond what one genius can do alone.
We need someone with leadership qualities to bring out the best in everyone.
And that's the realm of empire-building.
The Nanami Conglomerate taught me ever since I was little...
to hold back my emotions,
and to not drown in material desires.
But I absolutely disagree!
My philosophy of empire is different!
No one will follow a leader who isn't having fun!
To enjoy the world... That is the power of a leader who can move people!
Then our Kingdom of Science...
will have absolutely no problem.
There's only one correct way to get around in a mine...
Mine carts!
m 0 0 l 132 0 l 132 100 l 0 100
Mine cart complete!
Holy crap, this is fun!
I don't care if you're the mastermind behind the petrification.
We're coming for you, Why-Man!
Mines
We'll come meet you,
Ishigami Village
after we gather an ungodly amount of science materials!

We've got ourselves an awesome distribution network for the Kingdom of Science!
