In an instant, the tyrannical shockwave of the Fistbone: Impact sent him flying like a dead leaf in a hurricane.
In that very moment—
Kong felt like he had been slammed by a mountain that reached the sky. His eyes bulged as a mouthful of blood surged up his throat.
"Puh—"
Blood sprayed from his mouth as the shockwave kept blasting him backward without mercy.
Finally—BOOM! He crashed into the solid, thick wall surrounding the training ground, demolishing it and kicking up a storm of dust.
The ground was left with a terrifying trench.
It looked like several excavators had run side-by-side across it, carving several meters deep and dozens of meters long.
Suddenly—
The entire arena went dead silent, as if the world had hit pause.
Not a sound.
Everyone was frozen in place—only the rubble still fell through the air, crackling as it hit the ground.
"Gulp—" Sengoku's eyes nearly popped from his skull as he swallowed hard. "One... punch?"
"That one punch… what kind of monstrous power is that?!"
His heart trembled as if it might leap out of his chest. Even the gusts of wind brushing past his cheeks couldn't snap him out of the shock.
Garp wore an equally dumbfounded expression, his jaw dropping so far it looked dislocated. "Nani!?"
"That punch…"
"That was insane!"
"That was AWESOME!!"
A second later, his eyes sparkled. "I gotta learn that move! I have to learn that move!!"
The power was astonishing, the destructive force absurd—it was just ridiculously overwhelming.
Right now, Klein looked just like Saitama-sensei from One Punch Man.
Absolutely badass!
Zephyr stood frozen, clutching a sword, his voice trembling: "B-Bro's strength... how is it this insane?!"
No one had an answer.
The entire arena was struck dumb in shock.
Then—
As the spectators and cadets snapped out of their daze, the entire place exploded in shouts of disbelief:
"What did I just see?? Klein—Klein sent Kong flying with a single punch?!"
"So the rumors are true?! I heard he sent Admiral Rampaging Bear flying with one punch too!!"
"That's terrifying! This isn't student-level power!"
"Such insane destructive strength... is there a monster living inside this guy?!"
"That punch… if it hit me, I'd be dead!!"
"No, we'd be mincemeat! We'd be pulp!"
"·······"
Shouts and screams echoed through the air. No one could believe what they had just witnessed—it was jaw-dropping.
Only now did everyone understand what Klein really meant when he told the crowd to stand back earlier.
Instructor Carter's smile had long vanished, replaced by sheer terror and shock. "This brat—this brat's strength, hey hey HEY—!"
"Holy shit!!"
Panic gripped his heart. Damn, he'd bet 200 million Berries on this with Klein!
If Klein won?
He wouldn't just lose money—he'd have to play the clown?!
Instructor Carter clenched his teeth and slapped his thigh. "Damn it! That little bastard Klein's a damn fox... That was my retirement fund...!"
He nearly spat blood, especially as he remembered how he initiated the bet... and how Klein had calmly accepted.
He was faking it.
That bastard had been acting the whole time!
"Hsssss—" Admiral Rampaging Bear inhaled sharply. "That punch... so strong. Even Marine HQ doesn't have many who can block that."
"They'd die!"
Standing beside him, Oharden nodded, his expression unusually grim. The shock in his eyes still hadn't faded. "Klein's strength… it far exceeds what we imagined. He was hiding it all this time!"
"If his opponent hadn't been Kong, none of us would've known a thing!"
Such self-restraint, coming from a cadet, was truly impressive.
And that monstrous power...
At that moment—
From the wreckage of the collapsed wall, Kong stood there, utterly…
Dazed.
What just happened was too much—too shocking to process.
He knew the punch would be strong. But not this strong.
"What a terrifying punch...!"
"Cough cough..."
He pushed away the rubble with a bloodstained hand. His lips were red from the impact. That punch kept replaying in his mind like a haunting vision.
His soul felt like it had been shaken.
Kong trudged forward from the dust, his whole body covered in grime. His pristine Marine uniform was tattered and shredded—a complete mess.
"Damn!"
Klein's eyes widened, furious. "Is this guy made of steel?! How the hell is he still standing?!"
He wanted to curse out loud. In anime, some characters just wouldn't die no matter how much you beat them.
Others? A single bullet could take them out.
Today...
He'd run into the former.
With bloodshot eyes, Kong locked his stunned gaze onto Klein and grinned, revealing bloodstained teeth. "Klein, I admit I was careless."
"I severely underestimated your strength."
He was surprisingly frank, unfazed by the people around him who had just watched him get bodied. His pride clearly wasn't ordinary.
And then—
He ripped off the rest of his shredded clothes, revealing a torso packed with bulging, rock-solid muscle.
A living sculpture of brutal power.
Kong's expression grew deadly serious."I, Kong, am willing to call you the greatest genius in Marine history!"
"And now—I'm getting serious."
Fwoosh—!
Shave!
He vanished in an instant, leaving behind a fading afterimage.
Klein calmed himself, his muscles locking up tight as he activated Observation Haki, tracking his opponent's movements.
Left!
Out of the corner of his eye, he caught sight of a massive, jet-black fist!
Wind howled as it came crashing in.
"Kami-e!"
Klein twisted his body at an unnatural angle, bending like paper to slip past the fist by a hair's breadth.
Then—his thigh exploded with power as he launched a devastating kick toward Kong's waist!
The terrifying momentum, combined with his Diamond Bones and Indestructible Body talents—
That kick tore through the air with a sonic boom, like a bomb going off!
BOOM—!
Kong brought up a leg covered in Armament Haki, blocking the blow. The clash produced a massive shockwave that rippled outward.
Dust and debris burst in every direction.
Cracks began spidering across the ground.
Feeling the monstrous strength behind Klein's kick, Kong's eyes lit up."Klein, your strength…"
Was every bit as strong as his own!
How could someone with a body so much smaller contain such raw power?
The two clashed leg-to-leg.
Klein leapt backward, creating distance, and also feeling the monstrous might inside Kong's frame.
'As expected, not an easy win. Even with Fistbone: Impact catching him off-guard, he's still battle-ready.'
The next second—
Klein raised his leg higher than any K-pop idol could dream, stirring the air.
"Rankyaku!"
A flurry of kicks unleashed crescent-shaped blue flying slashes into the air.
Whoosh whoosh whoosh—!
Kong dodged left and right. The Rankyaku slashes exploded on the ground like cannon fire, blasting up clouds of debris and rubble.
"Klein!" Kong roared. "That fist technique you used last time—show me!"
His brutal fists rippled the air with shockwaves.
Fist against fist?
"Fistbone: Honesty!!"
