Dr. Stone (Kohaku x Male Reader)

Part 10 TREASURE BOX

(An: I'll have you guys know that Y/n and Senku are talking together to show how much of a bond they have as brothers. And whenever they speak the same thing together, Y/n always mouthed a countdown.)

Ocean

The Perseus is seen sailing towards its first destination, Treasure Island. As well as the place where the Science Bros claim is where they'll get their key ingredient to reviving humanity. It passes by a small landmass with petrified humans on it.

Senku: We may've been hit by the petrification beam thousands of years ago.

Y/n: *Chuckles with his brother* But we're not gonna take it lying down forever. No sir-ee.

Senku: It's finally time to get started on reviving humanity.

Science Bros: All seven-billion of us.

Taiju: *Excited* Really?!

Gen: How many millions of liters of revival fluid do you think that'll take?

Senku smirks and looks to his brother before the said blond puts his left pointer and middle finger between his eyes as math equations appear around the crew. The ones who have yet to experience this were amazed.

Y/n: Seeing as we require approximately a soda can's worth of revival fluid for one person, which is 12 ounces, there being seven-billion humans on the Earth, and forty-two of those seven billion being revived already... *Opens eyes with a smirk* We will need exactly 2,484,176,468.34494 (Two-billion-four-hundred-eighty-four-million-one-hundred-seventy-six-thousand-four-hundred and sixty-eight point three four four nine four) liters of revival fluid to revive the rest of humanity.

Crew minus Senku: HUUUUUUUUHHHH!?!???!

Yuzuriha: *Too shocked* You just spit that number out like it was no big deal...

Senku: *Imitating Taiju* Well, while he was a statue, he added hundreds of billions of seconds worth of his mom's songs. So he's pretty good at it by now.

Taiju for some reason didn't feel insulted and let out a huge laugh instead. It brought back memories of their first year together in the Stone World.

Gen: *Too shocked* I guess we've got ourselves a human calculator to go with our human stopwatch...

Ryusui: *Too impressed* HAHAAA!! *Snaps* Never challenge Y/n Weinberg to a game of mental math! *Sinisterly proud* He always wins.

Kohaku: *Can't choose between being shocked or impressed* Just how are we going to get that much??? The Miracle Cave was our only source, and it's a pile of rubble.

Senku: Well, we don't plan to rely on nature's miracles anymore.

Taiju: *Thinks about it* Now that I think about it, the cave only gave us a slow drip of the stuff.

He thinks back to the slow pace of the dripping nitric acid in the Miracle Cave.

Taiju: If all it takes is a soda can's worth to revive one person, enough to revive one person only came every few days. Trying to bring back all of humanity like that would take forever! Especially knowing that we'd need over two-billion liters for every single human!

Senku: *Chuckles* Which is why we said "god-tier."

Y/n: Exactly. And be glad I didn't include the swallows, man. Our target is something that'll give us an unlimited supply of revival fluid. At least the nitric acid half of it.

They picture the island their parents landed on 3703 years ago and the six astronauts appearing on it.

Senku: And we're gonna find it on the Treasure Island where the Hundred Tales began.
