Krillin stood in front of Trunks, his orange Turtle School gi fluttering even though there was no wind.
He did not take any special stance. He simply let his hands rest at his sides, his smooth bald head reflecting the harsh sunlight.
[Ding! Extreme anger detected from the Host. Triggering S-rank emergency mission: Pest Control.]
[Mission Objective: Kill the Saiyan Nappa with absolute dominance.]
[Mission Reward: Saitama Template Fusion +1% (currently 36%), proficiency increase for the skill "Serious Punch," and the new achievement "The Overprotective Demon" unlocked.]
Krillin did not even blink. He casually dismissed the System notification from his vision.
Right now, he only wanted to do one thing.
"Phew..."
Krillin exhaled softly.
In an instant, a white shockwave burst outward in a ring centered on him.
This was no longer the calm, restrained energy he usually released.
This was a violent torrent of power capable of tearing through the atmosphere itself.
Until now, to avoid damaging Earth's ecosystem and to give the Z Fighters motivation to grow stronger, Krillin had always suppressed his combat power to around 500 in his base form.
Now, the limiters were gone.
The entire East City began to tremble.
Distant mountain ranges collapsed, and the clouds in the sky were torn apart, revealing the dark void of space beyond.
Beep beep beep beep beep...!
The upgraded Scouter on Vegeta's left eye began screaming with a sharp alarm that sounded like a violin string about to snap.
The numbers on the display were no longer jumping. They were spinning wildly, too fast for the eye to follow.
500... 8,000... 12,000... 18,000...
"This... how is this possible?!"
Vegeta jumped to his feet, his face pale as sweat poured down his forehead.
He pressed the Scouter's control button repeatedly, trying to restart what he believed had malfunctioned.
"It's broken! It has to be broken! How could someone on a remote planet like Earth have this kind of reading?!"
Reality answered him immediately.
Bang!
The Scouter exploded into fragments with a sharp crack, leaving a thin line of blood at the corner of his eye.
The final number frozen on the display was 22,000.
And that was only the instantaneous reading from the moment Krillin released his aura.
At the center of the battlefield, Nappa stood frozen in shock.
As a veteran Saiyan warrior who had conquered countless planets, he had faced many powerful enemies before.
But never despair like this.
The bald man standing in front of him did not feel like an Earthling.
He felt like an abyss.
Nappa tried to move. He tried to run. He even wanted to kneel and beg for mercy.
But his body would not respond.
His legs felt as heavy as if they were filled with molten metal, completely locked in place.
This was instinctive fear.
Like prey facing a predator.
"You... what... are you!!"
Nappa's teeth chattered uncontrollably as he spoke.
Krillin did not answer.
He slowly raised his right fist.
The movement looked slow, like an old man practicing Tai Chi in a park.
But to Nappa, it felt impossibly fast, sealing every possible escape route.
Krillin's eyes were calm and empty.
There was no anger.
No killing intent.
Only absolute calm.
"Normal Punch."
There were no visual effects.
No charging energy.
Not even the sound of wind breaking.
Krillin vanished.
In the next instant, he appeared directly in front of Nappa, his right fist lightly touching Nappa's armored abdomen.
Time seemed to freeze.
Then—
Pop.
A quiet sound echoed.
Like a watermelon bursting.
Like a balloon popping.
Nappa's massive body exploded outward from the point of impact before he could even react.
The force of the punch did not stop at the surface. It traveled through his body and detonated instantly.
His eyes widened in terror as his entire body turned into a cloud of blood.
The shockwave continued forward.
The mountain range behind him disappeared.
Even the sea thousands of meters away was split open, forming a massive vacuum channel stretching far into the distance.
Seawater evaporated.
Rocks vaporized.
Only several seconds later did the delayed sonic boom echo across the sky.
Nappa, a Saiyan elite with a combat power of 4000, vanished completely.
Not even a single intact bone remained.
Only a light rain of blood and fragments fell onto the scorched ground with a faint sizzling sound.
The battlefield fell silent.
Everyone stared with their mouths open.
Yamcha swallowed hard and said, "Is... is this Krillin's true strength? How much was he holding back during training? He was holding back an entire ocean!"
All three of Tien Shinhan's eyes lost focus as sweat ran down his face. He said, "One punch... he didn't even use a Ki Blast. Nappa's energy disappeared instantly."
Piccolo stared at Krillin's back silently and said, "Is this... the difference between us? I thought after half a year of training I could at least catch up. Now I can't even look up to him."
Trunks jumped excitedly and waved his hands. "Dad is amazing! That move was incredible! I want to learn that too! One punch turned that giant into fireworks!"
Krillin stood calmly in the falling blood mist, yet not a single drop touched him.
Everything was blocked by the invisible protective aura surrounding his body.
He casually shook his fist as if he had just swatted a mosquito.
Then he turned and looked toward Vegeta.
"Next."
His voice was soft but clearly reached across the battlefield.
Vegeta trembled and finally snapped out of his shock.
He looked at the place where Nappa had stood. Only a smoking crater remained.
Fear?
No.
The cold sweat on Vegeta's face disappeared and was replaced by excitement.
"Haha... Hahahaha!" He laughed wildly.
"Interesting! This is too interesting!"
He tore off his damaged cape and released his full aura.
Golden energy flared around him, blowing debris away in every direction.
"I thought this mission to Earth would be nothing more than cleaning trash. I never expected a monster like you to exist on this abandoned planet!"
Vegeta stared at Krillin intensely and said, "A combat power over twenty thousand... maybe even higher! Even in the Frieza Force, that would be top-tier!
Excellent! Only by defeating someone like you can I prove my pride as the Saiyan prince!"
He took a battle stance and shouted, "Come on, baldy! Let me see whether your fist is harder or the bones of the Saiyan prince are harder!"
Just as Vegeta prepared to charge—
[Ding! Congratulations to the Host for completing the mission "Pest Control."]
[Reward issued: Saitama Template Fusion +1% (currently 37%).]
[System Rating: SSS (A Perfect Strike).]
Krillin looked at the System panel and smiled slightly.
Mission complete.
Nappa was gone.
Experience gained.
Now it was time to return the spotlight to the real protagonist.
After all, if he defeated every enemy himself, Goku's half-year of training with King Kai would be wasted.
Besides, according to the original timeline, this battle between Goku and Vegeta was the beginning of their complicated relationship.
Interfering too much could affect what happened later on Planet Namek.
Thinking this, Krillin's overwhelming aura disappeared instantly.
His posture relaxed.
"Ouch..." He suddenly bent over and grabbed his lower back.
"I can't do it anymore! My back! That punch earlier was too strong. I think I threw my back out! Getting old is terrible. It's osteoporosis!"
Everyone: "..."
Vegeta nearly fell forward in disbelief.
He stared at Krillin angrily and shouted, "Are you kidding me?! With that kind of power, how could you possibly hurt your back?!"
Krillin ignored him completely and continued pretending.
"Goku! Goku! I'm done here. I'll leave this guy to you. It's a good chance to test your training with King Kai! I need to take Trunks somewhere safe. The kid was scared earlier and needs his father."
After saying that, Krillin used Instant Transmission to appear beside Trunks, picked him up, moved behind a distant rock, and pulled out a bag of sunflower seeds.
Trunks blinked and said, "Dad, your acting is terrible."
"Just eat your chocolate," Krillin whispered.
In the center of the battlefield, Goku scratched his head and smiled.
"Krillin... his energy isn't disturbed at all," He stepped forward toward Vegeta.
"Still, since Krillin gave me this chance, I won't waste it."
Goku stopped and released his energy.
"You're Vegeta, right?"
He took the Turtle School stance and said, "I'm Son Goku. I'm also the Saiyan Kakarot who grew up on Earth.
I don't care much about your ideas of killing, but as a martial artist, I want to see how strong the Saiyan prince really is."
Vegeta floated into the air and sneered.
"Kakarot. A low-class warrior sent to a low-level planet dares to speak like this to me? That baldy earlier had some skill, but you? I saw Raditz's report. Your combat power wasn't even 4000 back then.
Even if you came back from the dead, how much stronger could you really be?"
Goku smiled slightly, "Then let's find out."
A white aura burst from his body.
"Hah!"
