Your attacks are too shallow!

One of us must win the Grand Bout Tournament

so Ruri will get the cure-all drug!

All right then.

While Gen pulls the wool over Tsukasa's eyes,

we'll make this cure-all drug.

All right!

What will we make with science?

When building a civilization,

there is one material equally as valuable as iron.

The first man-made material in history

synthesized using science.

And that is glass.

What's that?

Now that we have electricity,

shouldn't we start making all sorts of medicine?

That's right.

Clay pots aren't going to cut it

if we want to make

the cure-all sulfa drug.

Glass can contain just about any chemical.

Glass is the foundation of chemistry.

It's ten billion percent simple to process,

yet it's incomparably tough and super strong!

It's completely transparent, so you can see the drug through it.

Really?

That's amazing!

Besides,

once we have glass,

we can get rid of that annoying mask,

so we can see what Great Detective Suika really looks like.

Senku, wait!

Suika said she doesn't want anyone to see her face.

Take a good look.

Oh my! Suika!

You're so adorable!

-What's happening? -What's happening?

My eyes have this fuzzy sickness.

Everything looks fuzzy to me.

I have to squint to see clearly,

so I end up looking like this.

It's embarrassing.

But when I wear this mask,

it's somehow a little easier to see!

That's the pinhole effect.

If you look at an object through a small hole,

the light passing through it narrows, bringing it into focus.

What does glass have to do with Suika's fuzzy sickness?

It's ten billion percent have something to do with it.

Listen, Suika.

You are nearsighted.

It's neither a disease nor a defect.

Nobody would care about that

in a scientifically-civilized world.

We have eyes of science, made from glass.

They are called glasses and they solve everything.

A scientist can even make eyes?

That's amazing!

Yes.

To tell you the truth,

I wanted to see the world clearly

even if it's just once.

I want to see everyone clearly.

I want to see how everyone really looks like

even if it's just once.

All right.

Then let's make this thing called glass!

Yes. What should we get, Senku?

The main ingredient of glass is a type of sand named quartz sand.

Chrome, don't you have that in your collection?

Well, I don't collect sand.

I saw a hint that will lead us to quartz sand though.

It's right here.

This is where I found this translucent rock as a kid.

Such a simple piece of information is worth a million to me.

That so-called translucent rock,

or crystal,

can be found in areas of decayed granite like this.

Also,

all the sand around here is the raw material to make glass.

Quartz sand.

This is amazing.

The white grains are falling out like crazy!

This is so much fun!

We are going to get loads of it.

Get as many translucent ones as you can.

Grind up your quartz sand into finer grit.

Then we mix it with other stuff and melt it in the kin.

What about other materials?

We've already gathered the ingredients.

Thanks to all of our efforts so far.

Calcium carbonate.

Which is ten percent of seashells.

Twenty percent cooked seaweed.

We used all this stuff when we made soap.

And…

Here it is! Galena!

I have lead now!

Add some lead in it

and we have super see-through lens glass.

It's gleaming and translucent like ice!

It's like a gem.

What's this weird tool?

Polishing glass manually can be excruciating.

Speaking about polishing,

this is where that super-solid stone,

the great corundum comes in.

Glass has a Mohs hardness of about six,

while corundum's is nine.

That makes it easier to polish.

-Another talk about stones? -Diamond's is ten, the hardest one.

-I just can't keep up with it. -Diamond must be really tough!

Suika,

can you see what's in front of you?

They are just sunflowers.

It's not like I can't see completely.

I knew it.

Your last hit was too shallow!

Kinro, that is your bad habit.

Distance is crucial in spear fighting.

Without a sense of distance,

you can never win over Magma!

Distance?

What can you do though, right?

I mean,

you have the fuzzy sickness.

That's why you always wear such a menacing look.

I'm born with that.

I don't get it.

If I were you, I would tell her right away,

"It's not my fault, it's my eyes.

I'm actually stronger than this."

A real man doesn't make excuses.

Don't tell anyone about it, Ginro.

Senku, Chrome, I didn't expect you to be so handsome.

What do you mean by that? Damn it.

After this, we'll make some glassware.

Now that we've upgraded Suika's labor potential,

we can start put together a chemical set.

Don't call her "labor potential"!

Say something nicer instead!

Why are you laughing?

GLASS OBTAINED!

It's time for our fun glasswork class!

Yes! Let's make a lot of them!

Just add these black stones, right?

More black stones are coming right up!

You're getting quicker, Suika.

I'm not as careless because my eyes aren't fuzzy anymore.

There are white bubbles coming out.

This is the foam that is created when you burn obsidian.

We're using the foam as insulation

to make a glassblowing furnace.

Next,

we'll make an iron blowpipe,

then we blow up the glass with air and that's it.

Well, it's just our first try.

When I first started making clay pots,

it took months before they looked decent.

Months?

We don't have so much time!

Ruri is getting worse too.

We're not glass craftsmen.

We can only keep trying.

Craftsmen?

Hey! Stop this, Chrome!

Who's that old man?

I'm so sorry, Mr. Kaseki,

but we really need your expertise.

You must be out of your mind to ask someone for help

by tying him up using a rope!

I absolutely refuse to get involved in any kind of sorcery!

See?

He just won't come and help us.

Mr. Kaseki.

I almost forgot to return the lacquer to you.

Is that so?

Sir.

Did you make that?

That long-lasting, durable shield,

in an environment with no iron tools and dye.

Yes,

I gave it to Kohaku's dad, Kokuyo,

when he won the Grand Bout Tournament.

I went all-out when I made it.

Those were the days.

The construction is ridiculously advanced for the technology.

So, I figured that there could be a highly-skilled craftsman among you.

I didn't expect him to be such a senile old man.

Did you also make that wooden bridge?

Yes, that's right.

You took the planks down without asking.

So, there is no way in hell that I'll help you…

What's this translucent stonework here?

If you won't help, then fine.

Just sit down there and watch

as I show you something great.

Kaseki, this stuff is going to be ten billion percent

exciting for you.

Heat makes it pliable and soft.

It's like blubber.

It's easy to mold!

Oh no. It's too thick.

What are you doing? My goodness!

He's not spinning it steadily.

That's why it didn't come out nicely.

Wait, did he do all this just to make me help out?

I can't stand it.

A dedicated craftsman like you

isn't going to stay put in front of something as fascinating as glassblowing.

I bet you can't sit still anymore,

Mr. Kaseki?

My goodness! I can't take it anymore!

I accept your challenge!

Leave this to me.

There is no way he could be that buffed.

Suika, water.

Here you go, sir.

Amazing! He's incredible!

Mr. Kaseki,

isn't this your first time seeing glass?

His years of experience in craftwork is on another level.

I've been a craftsman for 50 years, you know.

Aren't I amazing?

There are people like you in every age.

People with true talent who have spent

their whole lives dedicated to craftsmanship.

RESEARCH LABORATORY OBTAINED!

-All right! -Great!

Hey. What's wrong, Senku?

We worked hard to build a laboratory.

You should be more happy.

Yes, we deserve a pat on the back.

Next, it will be the dawn of chemistry.

Things are starting to look quite nice here.

Our Kingdom of Science

is going to be ten billion times more fun

than that Tsukasa Empire.

MAP OF THE KINGDOM OF SCIENCE

It has been a while!

It's me, Senku Robot.

Here is an overview of the Kingdom of Science!

This is the base camp of the kingdom.

It has a huge collection of minerals that Chrome has collected since he was a kid.

They are all wonderful treasures!

MAP OF THE KINGDOM OF SCIENCE

And as you know, the scientific gourmet, wild fox millet ramen.

I can eat bowl after bowl!

Incredible.

It's so incredible!

MAP OF THE KINGDOM OF SCIENCE

We rely on having power in numbers to make iron.

It operates at 1,500 degrees Celsius and beyond.

Hey.

That was really tiring.

MAP OF THE KINGDOM OF SCIENCE

To defeat Magma,

these are the training grounds of hell!

Actually, it's just a normal training ground.

Friendship, effort, and victory!

You're not one to talk!

You are really horrible, Ginro!

A fully man-powered generator that is really eco-friendly.

MAP OF THE KINGDOM OF SCIENCE

Blowing glass with the skill of an artisan.

It bends like clay.

The scorching hot glass is cooled slowly

so that it doesn't crack.

And next is laboratory.

With all kinds of insane chemicals,

we'll move forward on the path of making the sulfa drug.

MAP OF THE KINGDOM OF SCIENCE

What a view.

The Kingdom of Science is getting more incredible.

We have only made the bare necessities.

We wouldn't get anywhere if we were missing any one of these.

Was the technology even more incredible before the world collapsed?

Yes.

It took two million years to get there.

Now, we must catch up with it and surpass it.

Our first step

is the cure-all sulfa drug.

The sorcery team is so lucky.

They look like they are having so much fun with shiny stuff.

While we…

Hey, Kinro.

What if…

What if the spear tip were shiny?

Maybe it will give your fuzzy vision a better sense of distance

so you'll fight better.

What are you rambling about,

Ginro?

Hey, speaking of shiny…

Don't you think we should have

a golden spear and silver spear?

But only for the Grand Bout Tournament, okay?

We need it to win, right?

I don't know much about combat,

but they say they can defeat Magma with gold and silver spears.

Are they serious?

Senku, to borrow your words,

they just ten billion percent want gold and silver spears.

I mean,

now that you have all this thing called glass

and an amazing research laboratory,

I'm sure you can make me a silver spear.

And then taking down Magma will be a walk in the park.

That's right.

Now that we have glassware,

we can finally brace ourselves to get the most difficult material

to obtain in creating the cure-all drug.

All right.

Our laboratory's first development

will be the silver spear.

I'm sorry, Kinro.

Maybe it's because I'm cuter.

You don't look cute at all, idiot.

This could literally cost you your life,

Ginro.

In search of the greatest treasure in the history of chemistry,

a great adventure shall begin.

You'll have to risk your life in the ultimate danger zone

where you might die on the spot.
