"Wororororo! Linlin, stop dreaming," Kaido laughed loudly, resting his kanabo on his shoulder.
"There's no way in hell I'd give my son-in-law to you."
"And besides," he added smugly,
"none of your kids can compare to my daughter."
Big Mom's expression darkened.
Kaido wasn't wrong. Among her dozens of children, not a single one had mastered advanced Conqueror's Haki like Yamato had.
But honestly, that was mostly Big Mom's own fault.
She never taught her children how to train seriously. Unlike Kaido, who liked to "teach" his subordinates with a kanabo whenever the mood struck.
Especially Yamato.
Ever since Yamato started idolizing Kozuki Oden, Kaido had beaten her relentlessly in the name of "education."
Luo Xing even suspected that Yamato's terrifying strength in the original timeline had something to do with Kaido's brutal teaching style—
kind of like how three solid hits from Kaido had helped Monkey D. Luffy grasp advanced Conqueror's Haki and awaken his Devil Fruit.
Big Mom, humiliated by Kaido's mockery, snapped angrily:
"Hmph! Among my daughters, there's one your daughter will never surpass!"
"She's a member of the Three-Eyed Tribe. Once her third eye awakens, she'll be able to read the Poneglyphs!"
"And when that happens, the Pirate King will be me!"
Among the Big Mom Pirates, a brown-haired girl blinked her three innocent eyes in confusion.
She was Charlotte Pudding, Big Mom's thirty-fifth daughter—originally meant to be married off to Germa.
Now, Big Mom was clearly thinking about marrying her to Luo Xing instead.
Kaido snorted.
"So what if she can read Poneglyphs? I don't need that crap to become Pirate King!"
As usual, the two old rivals started arguing again after barely exchanging a few words.
Luo Xing coughed lightly and stepped in.
"Since we're allies now, we should try to keep things civil."
Yamato had only just been calmed down—there was no way Luo Xing was about to say something like
'If you insist on marrying off your daughter, I might consider it.'
Big Mom's sharp voice rang out:
"Kaido, you already owe me a huge favor! And now you've wrecked my palace!"
"If you won't give me your son-in-law, then you must help me achieve my dream!"
"I want everyone in the world to become giants!"
Big Mom had two lifelong dreams.
One was becoming Pirate King.
The other—ranked even higher in her heart—was turning everyone into giants like herself.
She'd been enormous since childhood, practically the size of a giant.
Now, she stood a towering 8.8 meters tall, more than a meter taller than Kaido.
Naturally, Big Mom didn't think she was abnormal.
She believed everyone else was.
And to "fix" them, she wanted to make everyone just as big as she was.
That was why she had once funded Caesar Clown through Doflamingo, pushing forward the inhumane gigantification experiments on children.
After killing Doflamingo and taking Caesar Clown under his control, Luo Xing had shut that disgusting project down immediately.
He hadn't expected Big Mom to still be obsessed with it.
Now, she clearly wanted him, the world's greatest scientist, to continue the research.
Kaido roared in anger:
"Turn everyone into giants? Linlin, do you think everyone's a freak like you?!"
Big Mom exploded.
"Who are you calling a freak, you damn ox-ape?!"
She grabbed Napoleon, ready to start another fight.
But then—
Luo Xing's thoughtful voice stopped her cold.
"Turning everyone into giants… might not be impossible."
Big Mom froze.
Then her face lit up with wild excitement as she stared at Luo Xing.
"You have a way?! What do you need—money, materials, anything! I'll give it to you!"
"I do have an idea," Luo Xing said calmly.
"There's a kind of super drug that can make someone grow to an enormous size instantly."
Big Mom was ecstatic.
"What drug?! Show me! Let me see it!"
Luo Xing shook his head.
"I haven't developed it yet."
Then he hesitated slightly, his expression turning troubled.
"The problem is… developing this drug requires an enormous amount of funding."
Big Mom might not have been clever, but even she understood such an obvious hint.
She waved her massive hand without hesitation.
"As long as it really works, I don't care how much it costs!"
Luo Xing replied instantly:
"I'll take as much as you have."
Big Mom, grinning foolishly:
"No problem!"
Katakuri and the others:
"..."
And just like that, Luo Xing casually squeezed hundreds of billions of Berries out of the Big Mom Pirates.
When they returned to Wano, every Beast Pirate was carrying an enormous treasure chest on their back.
Big Mom's children felt their hearts bleeding.
Hundreds of billions!
Even with Totto Land's wealth, that was a devastating loss.
"Big Brother Katakuri…" Brûlée asked tearfully,
"Are we going to starve now?"
Katakuri was utterly speechless.
That Luo Xing was clearly scamming their mother—and she'd walked right into it.
After a moment, he said calmly:
"We'll be fine. Once we divide Whitebeard's territory, we'll make it all back."
Then he added gently,
"Here, Brûlée. Take this Fairy Bean and heal your face first."
Brûlée hesitated.
"Big brother… what about the scars on your mouth?"
Despite his cold and stoic image, Katakuri was a hardcore sweet-tooth just like their mother.
As a child, he'd eaten so many donuts that his mouth had split open.
Hearing Brûlée mention it, Katakuri looked awkward.
He glanced around quickly to make sure no one else had heard, then finally relaxed.
…
Thanks to the Anywhere Door, the vast distance between Totto Land and Wano was crossed in an instant.
Looking at the piles of treasure, Kaido laughed until his mouth nearly split open.
"Linlin's still just as stupid as ever—strong body, empty head!"
And honestly, Kaido had the right to say that.
He might be physically powerful, but he wasn't stupid.
He just tended to rely too much on brute force and ignore details—like leaving Oden's retainers alive back then.
In Luo Xing's eyes, Kaido and King were actually the sharpest minds in the Beast Pirates.
The rest were mostly straightforward brutes like Jack.
After unloading the treasure, Luo Xing went alone into his laboratory.
He already had Caesar Clown's gigantification research data, and with the system's support, developing that super drug wouldn't be too difficult.
The drug he'd promised Big Mom was none other than the one from another world—
"King of Biceps."
A terrifying substance that could make someone under two meters tall grow to hundreds of meters in an instant.
Of course, the side effects were just as terrifying.
Total loss of intelligence.
The poor giant brother in that other world had even smashed his own brother to death by mistake.
Luo Xing had no intention of letting his own people use such a drug unless it was absolutely necessary.
Otherwise, the war wouldn't even start before a bunch of mindless giants tore each other apart.
As for how Big Mom would use it—or how badly it might backfire on her crew—
That wasn't his problem.
After all, he'd only promised gigantification.
He never said there would be no side effects.
With that thought in mind, Luo Xing began his research on the super drug—
King of Biceps.
