You're doing great, my adorable little cameras!

Now we don't have to feel bad about always relying on your eyes, Kohaku-chan.

Hey, ground search team, howdy do?

There's a suspicious blur over by that big river next to Mount Fuji.

Think you can check it out for me?

Yeah, we'll take care of it!

We've gotta take ten billion aerial photos before winter arrives.

Once everything's covered in snow, we're not gonna be able to spot a thing.

We'll find it with time to spare.

The black jewel slumbering beneath the earth...

Oil!

Dammit, man, are we ever gonna find this oil?

Ow!

A chestnut, huh?

We can prep for winter even better thanks to these photos!

We're deep into the fall already.

The harvest season is upon us.

It's only been a few months and it's already fully grown!

Wheat is freaking amazing!

No wonder it became such a staple around the world.

It's all-you-can-eat wheat!

F-Farming is torture on the back, man.

Don't worry, Yo!

Leave the rest to us!

We're still good to go!

You're the only one here with infinite stamina, jackass.

Farming might be far more efficient than hunting and gathering,

but it sure is hard on the body.

I'm beginning to understand why you need so many people for it.

Now that humanity has acquired its staple crop,

it's time for the grand opening of our Michelin three-star restaurant, Bistro Francois!

Understood, sir.

I'll begin working on the menu right away.

Allow me to peruse the aerial photos to locate ingredients.

Good thinking, guys.

Everybody's starting to get a bit worn down from all this extra physical labor.

Motivation alone isn't enough to power our muscles.

Manual labor is a science, too.

If the body's our engine, then food is our gasoline.

Ideally, we want something packed with protein and easy to preserve.

Don't forget "insanely delicious" and "gourmet as hell"!

Let's see...

Truffles? Caviar? Foie gras?

No way, that's completely absurd.

We don't have the ingredients for any of that.

"Absurd"?

I've never once heard Francois utter that word.

Well, just see for yourselves.

High-end gourmet protein that's easy to preserve?

Understood.

Then the dish to be prepared is boar rillettes with black truffles.

T-Truffles?!

And, since I suspected this might happen,

I've enlisted the help of our resident expert in the local flora and fauna.

Resident...

...expert?

Long time no see, guys!

Suika!

Francois really does think of everything...

My butler is the best!

Let's see...

It's kinda hard to tell what these long, fuzzy blobs are,

but it looks like one might be rubbing its body against a tree branch.

I'm not sure, but I think they could be boars!

It's pork time!

Well, the meat's taken care of, but where are we gonna find truffles?

Aren't they so rare that some people call them "black diamonds"?

Contrary to popular belief, truffles grow within many forests around the world.

Even in Japan.

For freakin' real?!

Got it. Black mushrooms, huh?

Suika was able to spot those boars in the photos.

This photo is from that area too, right?

If I look hard enough, I bet I can find the mushrooms.

Uh, it might actually be impossible to spot something that small in a photo.

It doesn't matter how good your eyesight is.

Well, you never know...

Kohaku-chan might just be able to do it.

It's true that she has naturally amazing vision, of course.

But have you considered that her ability might be more than just that?

She's honed her observational skills to the limit fighting for survival in this stone world.

I found them...

The black diamonds.

There's no way you could spot a mushroom in that blurry-ass photo.

What is this black splotch, then?

Yeah, that's definitely something, but what?

Given the scale of this image, it looks to be around the size of a large puddle.

No way...

The black jewel slumbering beneath the earth is seeping to the surface.

This discovery's worth its weight in gold!

It's the ultimate treasure trove we've been looking for this whole time!

The Sagara Oil Fields!

The photo's too blurry to tell exactly where it is, though.

Not a problem!

We'll comb the landscape using the old fashioned technique of divide and conquer!

Our role is to aid the search

by strengthening the bodies and minds of our guests using the culinary delights of our restaurant.

We still haven't found our black jewels, though.

Worry not, Suika-sama.

If there's one thing a boar knows well, it's the scent of our black jewels.

I'm not very knowledgeable about science,

but every chef worth their salt knows this fact.

The scent of truffles is similar to the sex pheromones of the wild boar.

This is why they excel at locating truffles growing underground.

Ooh, something yummy? Time to pig out!

Why yes, how could I forget?

This is why people stopped using boars and pigs to hunt for truffles.

Don't worry, Francois!

The Great Detective Duo, Suika and Chalk, is on the case!

Now that Chalk's got the scent, he can suss them out.

It's useless, man.

Damn it all. If only the photos were just a little less blurry...

This is rough.

Seriously.

Given the size of the puddle, we're basically looking for a needle in a haystack.

We need more clues.

Once the land is covered in snow, it will be impossible to find the puddle.

If we don't find it before then,

all of our hard work will go to waste.

My brain's been all over the place lately.

There must be something I overlooked.

Some hilariously obvious hint.

Floating around somewhere in my hippocampus...

Then the dish to be prepared is boar rillettes with black truffles.

Where are we gonna find truffles?

Aren't they so rare that some people call them "black diamonds"?

Suika was able to spot those boars in the photos.

This photo is from that area too, right?

We still haven't found our black jewels, though.

Worry not, Suika-sama.

If there's one thing a boar knows well, it's the scent of our black jewels.

If there's one thing a boar knows well...

The boars!

That's how the Sagara Oil Fields were discovered in 1872, right?

Uh, I'm not sure why you're expecting us to know.

Wild boars are know for playing in the mud.

But one day, some people found one that reeked of oil.

Naturally they were curious why, so they let it go and followed it.

Now that we have the truffles, we can start prepping the restaurant's first dish!

Let us begin without delay.

First, we'll simmer the boar meat for the rillette.

Is it just me, or does this boar smell like oil?

No simmering allowed!

We want you to take us to where you were playing in the mud.

To where the black jewel, oil, is.

Goink!

Oh, man...

She tamed it so quickly!

Thank you, Sagara!

Sagara?

Did you name the boar?

We're gonna be eating him, you know.

If you wanna make a friend, you gotta start by learning their name!

There's no doubt about it.

This is definitely the black puddle in the photo.

What are you doing, Senku?

The dark mud water is burning, even though it's liquid!

That's what gives us the power to move our boat, right?

Yup.

It took us a while, but we've finally found it.

Humanity has once again acquired the king of all fuels!

We've re-discovered the Sagara Oil Fields!

You did such a good job, Sagara!

But now Francois is going to cook you up...

Francois!

I need your opinion, as a professional chef.

Is this boar even edible?

No.

It reeks of oil, making it unfit for consumption.

The stench has seeped in too deeply.

Well, there you have it.

Let him loose or bring him home—your choice.

Thank goodness!

Now we can be friends forever!

It's bad for morale if you don't reward people for their accomplishments.

Of course.

But was that really the only reason?

Huh? What other reason could there be?

Better to test the oil sooner rather than later.

Is that...

Yep, a motorboat.

Oh, sorry, were you asking about the engine?

It's a Stirling engine.

Remember the Stirling refrigerator we made to freeze Tsukasa?

It decreases the temperature when you pump a piston.

This is the same concept, but in reverse.

Uh, no...

We use an increase in temperature to pump the pistons.

I wasn't asking about the engine.

With this boat, we finally have everything we need.

We can go out to sea!

Well, that all depends on whether the oil we've got is pure enough.

Is it really safe to pour this in? Are you sure?

Is that a love potion I smell?

Find somebody you want to enchant, Senku?

Love potion?

What are you on about, Taiju-chan?

You made some for me back then, remember?

You gave it to me so I'd have the courage to confess to Yuzuriha.

It was during the final moments before we all got petrified.

It's a drug that'll stimulate your pheromone output to the max.

A love potion, if you will.

Take this, and you're set, ten billion percent.

You're totally right! I almost forgot about that!

You seriously never realized, you big oaf?

It was gasoline the whole time!

What?! Are you serious?!

If you thought it smelled the same without even knowing it was gasoline...

Well, it must be true.

The oil from the Sagara Oil Fields is the same quality as the stuff I made from that bottle cap.

It's got a carbon count of 5-to-12, meaning it makes for high-grade gasoline.

So what you're saying, Senku, is that the last thing you made with science in the old world was gasoline?

That would mean, as of this moment, we've officially caught up.

And before long, we'll be coasting on by!

All aboard! We're leaving port!

Hot damn, it's so fast!

It's time to venture beyond Japan!

Humanity can once again set out on the open seas

and sail to a new world...

through the power of science!

This is crazy! The coast's already gone!

The horizon only extends a few kilometers, after all.

This is my first time being surrounded by nothing but water.

It's sort of lonely, almost as if we're the only ones left on Earth.

Yeah.

Even if you know 70% of the globe is covered in water, it's completely different seeing it firsthand.

I'm not even sure which direction we came from anymore.

Can we really find our way back?

And this is only a fraction of the distance we're planning to go eventually, right?

The ocean really is crazy.

Worry not.

For we have my sextant!

Didn't you say it was basically trash?

Yeah.

We'll be risking our lives during our real voyage.

We're gonna want ten billion percent accurate coordinates.

Well, sure, we all want them, but how exactly are you planning to get them?

By making a GPS.

G...

...P...

...S?!

Whazzat?

Cell phones and car navigation systems used it.

It estimates your position based on signals from satellites.

Car navigation?

Satellites?

There's no way we can make satellites!

Well, duh!

That's why we're gonna be using a massive land-based radio tower.

Since the waterwheel packs a lot more oomph than our batteries,

we can give our cell phone signal the boost it needs!

Switch on!

Time to test the signal.

We're gonna be counting on your ears for this, ever-trusty sonar operator.

Just keeping on spinning the antenna around.

Based on the direction and intensity of the signal, we can calculate our distance from the tower.

This part is so analog it almost feels like a DIY project.

Have you found your bearings yet, brave sailors?

Yep, we're good to go!

Ahem.

Ruri-chwan?

Remember that first phone call between you and Chrome?

The one where he chickened out and couldn't tell you how he really felt.

Did you see that, Ruri? Pretty awesome, right?!

That's the power of science!

Since this is the first call between land and sea, why don't you do the talking this time?

There's nothing wrong with the girl making the first move!

F-First move?

Whatever could you mean?

Chrome...

Everyone's encouraging me to—

Ah-ha, how cliché!

A burst of static right when things are getting juicy.

That's not static.

How is this possible?

There's suddenly a powerful signal drowning everything else out.

But it's too saturated for me to tell where it's coming from.

Plasma from space, maybe?

Can't be.

This is no natural phenomenon.

Whatever it is, it's intentional.

It's tuned to the exact frequency we're using.

Someone must have noticed the powerful signal coming from our radio tower.

Wait, what do you mean, "someone"?

If somebody else was able to revive, it's certainly possible.

Wait a second...

Isn't that Morse code?

It's a message for us.

It's repeating the same string over and over.

Um, let's see...

Is that a W?

H...

Huh?

W. H. Y.

Huh?

"Why?"

That's it.

Why, why, why, why?!

Hey.

Are you the mastermind behind humanity's petrification?

We meet at last.

I've been waiting 3,700 years for this moment.

Now this is exhilarating!
