Kai stood inside the gravity chamber, breathing slow and steady. The walls around him hummed with power, glowing faintly with red lights.
The reinforced flooring, thick alloy panels, and futuristic control panel made it feel like the inside of a Saiyan training pod — or a gym designed by a supervillain with taste.
He cracked his knuckles.
Outside the observation glass, Bulma leaned casually against the console, sipping her ever-present mug of tea.
"You sure you wanna start tonight?" she asked through the intercom. "The system's still not fully tested. You could end up crushed into a meat pancake."
"I like my pancakes with protein," Kai replied.
"Just don't break anything."
"Your faith in me is so inspiring."
He tapped the screen.
Gravity: 2x. Confirm.
The machine rumbled.
Then gravity hit him like a boulder.
Kai dropped instantly. His knees buckled, shoulders hunched. He gritted his teeth as the weight of two Earths pressed down on him.
"Guhhh—this feels like I got hit by Nappa's head."
Outside, Bulma chuckled. "That's about what I expected."
He couldn't even lift his arms.
'Come on. You're the Adaptation Guy. This is what you do. You've walked off concussions and crater impacts. This is just a weighted blanket with rage issues.'
[DING]
[Environmental Stress Detected – Gravity x2]
[Adaptation Commencing…]
[Skeletal Reinforcement +10%]
[Muscular Density +7%]
[Energy Circulation Efficiency Boosted]
Kai sucked in air as his limbs trembled… then slowly stopped shaking.
The pressure started lifting — or rather, he started getting stronger.
He rose to his feet. Straightened his back. Flexed his arm.
"…Okay, yeah. That's hitting different now."
Outside, Bulma blinked.
"Wait… you're standing?"
Kai smirked, rolling his shoulders.
"Just needed time to get used to it."
"…That fast?"
"I'm very adaptable. And humble."
She raised a brow. "You're also still shirtless."
"You're still here," he shot back. "Kinda weird you're hanging around watching me be sweaty and heroic, just saying."
Bulma rolled her eyes. "You're impossible."
"Still watching though."
"Goodnight, weirdo."
She stormed off, muttering something about egos and protein powder. Kai watched her go with a grin, then turned back to the chamber.
He set the gravity to 5x.
Then 8x.
Then 10x.
His body screamed… and adapted.
Muscles reshaped. Bones compressed. Ki flow increased.
[DING]
[Adaptation Success: Gravity x10
][Performance Enhanced – Speed, Strength, Reaction Time +25%]
He kept going.
12x. 15x. 20x.
He was drenched in sweat. His breathing sharp. But not in pain. Not broken. He was thriving.
Every punch cracked the air. Every movement left a blur.
By sunrise, the entire chamber smelled like determination and possibly burnt ozone.
Kai stood by the scanner console the next morning, towel over his shoulder.
He pressed a button and watched the numbers flicker to life.
Power Level: 300,000
"…What."
He blinked. Slapped the side of the screen.
Still 300,000.
"Okay no, that's… that's not real. I haven't even done a full arc yet! Goku doesn't get this until Namek!"
[DING]
[Adaptive Trait Synergy Reached – Ki Output Amplified by Gravity Conditioning]
'Great. Now I'm a walking nuke.'
He sighed and dragged the slider down to hide the truth.
Power Level Set to: 8,000 (Locked Concealment Active)
'Yeah. That's better. Let's not get Vegeta showing up early out of ego panic.'
Exhausted, buzzing with power, and ready to finally wash the smell of gravity out of his pores, Kai wandered down the hallway and pushed open the bathroom door.
Steam.
Towels.
Water dripping on tile.
And Bulma.
Fresh out of the bath. Towel wrapped tightly around her, hair damp, skin glowing. She turned at the sound of the door and froze.
Kai froze harder.
A long beat.
Then—
"AAAAAHHHH! KAI!!"
"OH MY GOD I DIDN'T SEE ANYTHING I SWEAR—"
Bulma shrieked, grabbing the nearest object — which turned out to be a shampoo bottle — and launched it at his head. He ducked. The second object — a loofah — smacked him square in the face.
"I THOUGHT IT WAS EMPTY I'M JUST HERE FOR A SHOWER I'M NOT A PERVERT I PROMISE—"
"GET OUT!!!"
More things flew. A soap bar. A conditioner bottle. A toothbrush that hit him with surgical precision.
Kai stumbled back into the hallway, face red, nose bleeding, heart rate at Super Saiyan levels.
He slammed the door shut behind him.
'Okay. Okay. Not dead. Just humiliated.'
The door cracked open slightly, and Bulma's red face peeked out.
"If you ever walk in on me again, I'm launching you into orbit."
"Totally fair," Kai coughed, still holding his nose. "Totally fair…"
The door slammed shut.
Kai sighed.
[DING]
[Embarrassment Resistance +1%]
