[00:08] Chrome
    This small chunk won't be enough,
    but it came down the stream in the cave.
[00:12] Chrome
    There must be tons further inside.
[00:15] Chrome
    Tons of this heat-resistant
    treasure called tungsten!
[00:18] Senku
    We only have one set of
    materials left to make a light.
[00:21] Senku
    The last member of the
    exploration team will be...
[00:28] Senku
    Magma.
[00:30] Senku
    Tungsten's tough as hell. We're going
    to need brute force to collect it.
[00:36] Senku
    Let's go cave diving.
    We're a trio of spelunking buddies.
[00:41] Senku
    To the fun treasure dungeon!
[00:45] Kohaku
    Senku, Chrome, and Magma?!
[00:49] Suika
    I've never heard of such a risky group.
[00:52] Ginro
    I-I-Is that even safe?
[00:54] Ginro
    He might be like, "I'm the chief!"
    and attack you or something, Senku!
[00:59] Senku
    Come on, let's get going,
[01:02] Senku
    the three of us.
SIGN    Vacuum Tube
[01:04] Senku
    We're after the magic stone that we'll
    need for making vacuum tube filaments:
[01:09] Senku
    scheelite, which glows blue
    under ultraviolet light.
[01:12] Senku
    The most heat-resistant metal
    in the world, tungsten!
[01:17] Chrome
    This chunk came down a
    stream in the cave, too.
[01:20] Chrome
    There must be a treasure trove further in.
[01:22] Senku
    I'm counting on you to take
    us to the cave, Chrome.
[01:26] Chrome
    Got it!
[01:28] Magma
    Going into the caves with
    two science users...
[01:31] Magma
    No one will be watching.
[01:53] Gen
    He's finally gone.
[01:57] Gen
    Senku-chan's gone from Ishigami Village.
[03:44] Senku
    The water's lukewarm.
[03:48] Senku
    We can definitely expect some treasures.
[04:01] Chrome
    Yo, Senku...
[04:03] Chrome
    Was it honestly a good idea
    to bring Magma along?
[04:07] Chrome
    He's a meathead who doesn't care about
    anything but being king of the hill.
[04:11] Chrome
    He's totally intent on snuffing you out
[04:13] Chrome
    when you least expect it
    and taking over the village.
[04:17] Senku
    Think about what's going on.
[04:19] Senku
    We desperately need tungsten
    in order to make cell phones.
[04:24] Senku
    That treasure is in the depths of the cave,
[04:26] Senku
    and to dig it out, we need
    Magma's power desperately.
[04:30] Senku
    The situation is ten billion percent simple.
[04:34] Senku
    We have to do it, so there's no point in
    thinking about the buts, what-ifs, or risks.
[04:41] Chrome
    Still, though...
[04:43] Chrome
    If Magma were to shove us down
    and say we died in an accident,
[04:46] Chrome
    it'd be the perfect crime.
[04:48] Chrome
    Besides, if he takes our heads
    to Tsukasa, and science vanishes,
[04:52] Chrome
    Tsukasa won't attack.
[04:55] Senku
    No way the meathead's thought that far ahead.
[05:08] Senku
    Get back!
[05:11] Chrome
    What's up, Senku?
[05:14] Senku
    It's mica.
[05:15] Senku
    It's like Baumkuchen...
    which doesn't help, I guess.
[05:19] Senku
    Even though it's a rock, it's brittle
    enough to break with your fingers.
[05:24] Senku
    Look.
[05:26] Senku
    They're natural pit traps.
[05:28] Chrome
    Damn, nature's traps are nasty.
[05:33] Magma
    Would you be stuck if you fell into one?
[05:36] Chrome
    Yeah.
[05:37] Chrome
    Try to get back up with a rope or ladder,
[05:39] Chrome
    and it'll cave in on you and bury you alive.
[06:00] Chrome
    No! Let go, Senku!
[06:02] Chrome
    It's going to cave in under your feet!
[06:05] Chrome
    Didn't you see that?
[06:06] Chrome
    Magma tried to shove us into the mica pits!
[06:18] Magma
    Yeah, that's right!
[06:20] Magma
    I came to this cave to kill you two!
[06:23] Magma
    You little twigs act so big, but you're
    so useless, you can hardly even hunt!
[06:30] Magma
    The strongest becomes the
    boss and gets the women,
[06:33] Magma
    and the village becomes stronger.
[06:35] Magma
    That's mother nature.
[06:36] Magma
    That's life.
[06:38] Magma
    "Science," my ass!
[06:40] Magma
    Senku, maybe in your world,
    the twigs controlled the muscles,
[06:46] Magma
    but this is the world of stone!
[06:49] Magma
    You're the one getting in our way!
[06:52] Magma
    Damn it, Senku, if only you hadn't
    come to Ishigami Village that day,
[06:59] Magma
    I would have been in power.
[07:02] Magma
    I'm the one who's truly strong.
[07:07] Magma
    I'm the number one man!
[07:15] Chrome
    Senku! Magma!
[07:38] Magma
    Quit wandering around!
[07:40] Magma
    You're getting on my nerves!
[07:42] Senku
    I'm measuring stuff.
[07:44] Magma
    There's no way we're
    getting out of this hole.
[07:47] Senku
    It's ten billion times better than just
    sitting and waiting like some idiot.
[07:51] Senku
    Keep raising your voice like a dumbass,
    and it'll cave in and bury us alive.
[07:56] Magma
    You damn twig...
[08:02] Magma
    Are you messing with me?!
[08:05] Magma
    I'll kill you, you little twig!
[08:06] Senku
    I told you, it'll cave in if you keep shouting.
[08:13] Chrome
    If we keep pouring in water
    from that pond over there,
[08:16] Chrome
    you might be able to swim back out.
[08:22] Magma
    It's never going to work
    if you pour it that slowly!
[08:25] Chrome
    Slow and steady wins the race, right?
[08:27] Chrome
    It's better than doing nothing!
[08:29] Senku
    Hang on.
[08:30] Senku
    That's not bad.
[08:34] Senku
    We have no use for resignation
    or for arguing about diligence.
[08:37] Senku
    Science determines whether it'll work or not.
[08:41] Senku
    Connecting the gas mask tubes will give us
    a good meter of drop height from the surface.
[08:45] Senku
    If the inner diameter of the tube is
    two centimeters, by Torricelli's law,
[08:48] Senku
    the flow will be 0.00139
    cubic meters per second.
[08:51] Senku
    If the hole is 28 cubic meters,
    that's 20131.68 seconds, or 5.59 hours.
SIGN    Q: Flow
        Q=AV (A: tube cross-section area, V: fluid speed)
        V=√2gh (Torricelli's law)
                     (g: gravitational acceleration, h: height of fluid surface)
    
    Q=(0.01)²xπx√2x9.8x1
    =0.001390842357211
    
    Volume of hole
        V=2x2x7 (Base is 2 square meters, depth is 7 meters)
        =28
    
    Therefore, the time to fill the hole with water is...
[08:58] Senku
    Since it's lukewarm, we should
    just barely avoid hypothermia.
[09:05] Senku
    Chrome, I'm going to tell
    you how to craft something.
[09:08] Senku
    Can you do it?
[09:11] Chrome
    Yeah, of course I can.
[09:13] Chrome
    Don't underestimate Chrome the science user!
[09:26] Senku
    See? I told you.
[09:28] Senku
    We're screwed if any one of us is missing.
[09:31] Senku
    The twigs controlled
    the muscles in my world?
[09:35] Senku
    Obviously not.
[09:37] Senku
    We were just divvying up the work.
[09:39] Senku
    In a technological civilization,
    you need twigs like us,
[09:43] Senku
    and we need brawny meatheads like you.
[09:47] Senku
    Even someone who's got nothing going
    for them can come in useful someday.
[09:52] Senku
    It doesn't matter who's
    the boss or who's on top.
[09:56] Senku
    There are all kinds of people.
[09:58] Senku
    And that equals strength.
[10:02] Magma
    I don't care about your babble.
[10:04] Magma
    Senku, you took the throne from me.
[10:08] Magma
    That's all.
[10:09] Senku
    Yeah, you're right.
[10:12] Senku
    But in exchange...
[10:19] Senku
    You get to see all the insane stuff
    that humanity worked together
[10:22] Senku
    for two million years to build.
    Stuff you never would've seen otherwise.
[10:26] Senku
    And I'll show you so much of it,
    it'll make your head spin.
[10:46] Chrome
    How is the water going from low to high?
[10:50] Senku
    Time for happy grade school
    science: the siphon!
[10:54] Senku
    I'll explain, just in case.
[10:56] Senku
    Fill a tube with water, then take it to
    a point lower than the water surface.
[11:02] Senku
    The water will flow upward
    and continue flowing.
[11:05] Senku
    It'll even work in your bathtub. Give it a try.
[11:16] Chrome
    This is bad.
[11:18] Chrome
    It's going to take a while longer
    for the water to fill up,
[11:20] Chrome
    but Senku's almost out of energy.
[11:25] Magma
    You go ahead and get up, little twig.
[11:29] Magma
    I'm the number one power of the
    Ishigami Village, living by the sea.
[11:32] Magma
    Don't underestimate me.
[11:37] Magma
    Senku!
[11:39] Magma
    I don't care if you're the boss anymore.
[11:42] Magma
    At least, until we deal with that Tsukasa guy.
[11:45] Magma
    But if you show me anything
    lame, I'll kill you!
[11:58] Senku
    Yeah, that works for me.
[12:02] Senku
    There's no way science could be lame.
[12:16] Senku
    Magma's brute strength got us
    out of the worst-case scenario.
[12:22] Chrome
    Worst-case scenario?
[12:23] Magma
    The fact that we'd have been dead
    had our bodies gotten any colder.
[12:28] Magma
    This is why I can't stand you little twigs.
[12:31] Senku
    No.
[12:33] Senku
    The worst-case scenario that would
    have occurred if we'd gotten any colder...
[12:37] Senku
    is...
[12:40] Senku
    Magma and I would've had to hold
    each other to maintain our body heat.
[12:46] Chrome
    That definitely is the worst-case scenario.
[13:23] Senku
    I was right!
[13:26] Senku
    I found it.
[13:27] Senku
    This striped rock face...
[13:30] Senku
    This dungeon we're currently in...
[13:34] Senku
    It's a skarn deposit.
[13:36] Senku
    We can get a stupid amount
    of sweet minerals here.
[13:39] Senku
    It's nature's treasure chest.
[13:42] Chrome
    This is crazy!
[13:44] Chrome
    White, black, blue, gold...
[13:47] Chrome
    It really is clearly separated into stripes!
[13:50] Chrome
    I've never seen a rock like this!
[13:53] Magma
    A rock is a rock, isn't it?
[13:55] Senku
    The magma underground boils water
    that gets into the white rocks,
[14:00] Senku
    the limestone, that's all over the place.
[14:04] Senku
    All the stuff that's inside the
    hot water seeps into the rocks,
[14:09] Senku
    transforming it into all
    different kinds of rocks.
[14:11] Senku
    That's a skarn deposit, nature's treasure chest.
[14:15] Chrome
    I see.
[14:17] Chrome
    That's why the parts around the
    cracks transform and form stripes.
[14:21] Senku
    In other words, with
    Magma's strength on our side,
[14:24] Senku
    we're able to acquire super-rare gems.
[14:31] Senku
    All right, we're here.
[14:33] Senku
    The gems we're after are inside this wall.
[14:36] Senku
    The rocks are hard as hell.
[14:38] Senku
    We twigs are useless for digging them out.
[14:42] Chrome
    We're counting on you, number-one power.
[14:46] Magma
    I didn't want to attack you head-on
    and get countered by science weapons.
[14:52] Magma
    But you wouldn't be alarmed if I were to raise
[14:54] Magma
    a weapon while I'm digging
    for treasures, would you?
[14:58] Chrome
    You wouldn't—
[15:00] Magma
    That's right!
[15:01] Magma
    The backs of your heads
    are wide open right now!
[15:10] Magma
    And I was going to murder you.
[15:14] Senku
    I'm sure you were.
[15:16] Senku
    That's why you couldn't help but
    save us back at the mica hole.
[15:21] Senku
    I know you weren't trying
    to shove me into the hole.
[15:25] Senku
    You were trying to save me.
[15:38] Chrome
    Magma.
[15:42] Chrome
    Sorry.
[15:43] Chrome
    I insulted you.
[15:47] Chrome
    Hit me.
[15:52] Magma
    I don't care anymore.
[15:54] Magma
    It doesn't change the fact
    that I was going to kill you!
[16:02] Chrome
    The most heat-resistant rock in the universe!
[16:04] Chrome
    It's ours!
SIGN    Tungsten acquired!!
[16:10] Chrome
    Yeah.
[16:12] Chrome
    Tungsten's an insane treasure...
[16:16] Chrome
    but in this dungeon of treasures,
    the three of us found
[16:19] Chrome
    an even more precious treasure:
    the treasure of friendship.
[16:27] Senku
    What are you even talking about?
[16:28] Senku
    That's so cringy.
[16:30] Magma
    Yeah, totally cringy.
[16:31] Chrome
    Sh-Shut up!
[16:33] Chrome
    I regretted it the moment
    it came out of my mouth!
[16:36] Chrome
    Why are you two suddenly hitting it off?!
[16:41] Chrome
    Oh, man, there's way too much treasure here!
[16:44] Senku
    Look! Manganese!
[16:45] Senku
    Manganese that's used
    for manganese batteries!
[16:48] Senku
    Copper pyrite!
[16:49] Senku
    Sphalerite!
[16:51] Magma
    They're just rocks!
[16:52] Magma
    Are you done yet?!
[16:54] Magma
    The sun's going to set!
[16:59] (Flashback) Gen
    Bring Senku-chan back by
    evening three days from now.
[17:03] Gen
    If you do...
[17:06] Magma
    We're heading back!
[17:08] Chrome
    Oh, come on, just a little longer.
[17:11] Senku
    Yeah, we found a mountain of treasure.
[17:14] Magma
    You little twigs aren't going
    to carry all that anyway!
[17:18] Magma
    Hurry up!
[17:20] Chrome
    Why are you suddenly in such a hurry?
[17:35] Senku
    What the hell are you doing?!
[17:36] Chrome
    Where are you taking Senku?! Hey!
[17:42] Gen
    Hey, Senku-chan.
[17:44] Gen
    Welcome back.
[17:46] Senku
    Huh? What's going on?
[17:49] Kohaku
    Don't bother trying to call for help, Senku.
[17:52] Kohaku
    We're all working with Gen.
[17:57] Senku
    So you bastards finally
    figured out the hack, huh?
[18:01] Senku
    All you need to do is hand science
    and my head over to Tsukasa,
[18:04] Senku
    and the village is safe. It's perfectly logical.
[18:15] Gen
    I have no idea what you're
    talking about, but...
[18:42] Senku
    An astronomy telescope...
[18:46] Senku
    Or rather, an observatory...
[18:51] (Flashback) Senku
    I'm going to space.
[19:15] Kaseki
    January Fourth...
[19:16] Kaseki
    Rock Day!
[19:17] Kohaku
    I heard it's your birthday today, Senku.
[19:21] Suika
    We all got you a birthday gift.
[19:31] (Flashback) Gen
    He's finally gone.
[19:35] (Flashback) Gen
    Hey, guys, hear me out.
[19:39] (Flashback) Gen
    I have an awesome idea.
[19:43] (Flashback) Gen
    I mean, I just vaguely remembered that
    you can put two lenses in a tube.
[19:49] (Flashback) Gen
    It's half-assed, but whatever.
[19:51] (Flashback) Ruri
    Hey
[19:53] (Flashback) Ruri
    These people would like to help.
[20:01] Carbo
    Senku better get me something
     even more awesome for my birthday.
[20:07] Carbo
    This is way too much work, man.
[20:10] Mantle
    Yeah.
[20:12] Gen
    The whole village worked hard to make this.
[20:15] Gen
    You're going to have to fine-tune
    it yourself, Senku-chan.
[20:19] Mantle
    Yeah.
[20:22] Ginro
    Hang on, Senku! Are you moved
    for the first time in forever?
[20:27] Ginro
    You can cry, you know.
[20:29] Ginro
    You don't need to hold it in.
[20:31] Kinro
    You're so low, Ginro.
[20:31] Kinro
    Go on! Go on! Go on!
[20:35] Senku
    Good job, everyone!
[20:37] Senku
    This is extremely practical.
[20:39] Senku
    We can use it on our
    watchtower against Tsukasa.
[20:42] Kohaku
    Y-Yeah, that's true.
[20:45] Gen
    Your feedback's as rational as ever.
[20:50] Senku
    A guy doesn't bother
    bringing up his own birthday.
[20:56] Senku
    How did you know it was today?
[20:59] (Flashback) Gen
    Our internal clocks are messed up
    from the petrification, though.
[21:03] (Flashback) Gen
    I don't even know how old I am anymore.
[21:06] (Flashback) Senku
    Think about how many days you've been alive.
[21:09] (Flashback) Gen
    What about you?
[21:11] (Flashback) Senku
    6,268 days.
[21:14] Senku
    Oh... So you used a leading question on me.
[21:17] Senku
    Still, you couldn't have figured it out
    if you didn't know when I revived.
[21:22] Gen
    Don't you remember?
[21:23] Gen
    You wrote the day your
    petrification was undone...
SIGN    AD 5738
    April 1
[21:29] Gen
    by the miracle cave,
[21:32] Gen
    as soon as you woke up.
[21:37] Gen
    So he wrote this when he was un-petrified?
[21:41] Gen
    How did he know what day it was?
[21:43] Gen
    Was he... The whole time?
[21:47] Gen
    This dude's totally insane.
[21:52] Gen
    Come to think of it,
    ever since the beginning...
[21:55] Gen
    Since before I met you...
[21:57] Gen
    I've been rather fond of you, Senku-chan,
    setting aside personal gains.
[22:04] Gen
    I'm sure it's the same
    for the other villagers.
[22:08] Gen
    You might say that's cringy, though.
[22:16] Senku
    Yeah, that's cringy.
[22:18] Gen
    See?
