Two years passed in the blink of an eye.
Life within Foosha Village remained peaceful and uneventful, far removed from the chaos consuming the Grand Line.
Kahn was now three years old.
Yet despite his age, his physique already appeared abnormal.
He stood nearly a head taller than most children in the village, and the lean muscles beneath his skin had become increasingly visible from constant physical training.
What had once started as simple morning jogging had evolved into something ridiculous.
One lap around the village became three.
Three became five.
Now, Kahn routinely ran ten laps around Foosha Village every morning before sunrise.
At this point, the villagers had simply accepted that the Roger twins were strange children.
Whenever Kahn passed by during his runs, elderly villagers occasionally tossed him fresh fruit or bread casually as if feeding a hardworking stray dog.
Meanwhile— Ace had grown into exactly the kind of disaster everyone feared.
Portgas D.
Ace was only three years old, yet already possessed terrifying destructive tendencies.
He pulled half the beard from Woop Slap.
He shattered wooden cups inside Makino’s tavern almost weekly.
And whenever Margaret scolded him, Ace usually responded by screaming loudly or breaking something else out of spite.
Eventually, Kahn developed an extremely efficient method to control him.
He simply walked over silently.
Then punched the wooden wall beside Ace.
Bang.
A deep fist imprint would instantly appear in the solid wood.
Ace would immediately become obedient.
Sometimes, overwhelming physical suppression worked better than brotherly affection.
Then one day— The peaceful routine ended.
A massive Marine battleship with a giant dog-head figurehead docked at Foosha Village’s harbor.
Only one person in the Marines used such a ridiculous warship.
Monkey D.
Garp had returned.
Wearing his white Marine coat of justice proudly over his shoulders, Garp strode through the village carrying two enormous bags of senbei crackers.
“BWAHAHAHA!” “My grandsons!
Did you miss your grandpa?!” His booming laughter echoed across nearly the entire village.
Nearby, Ace was currently chasing a stray dog while swinging a wooden stick wildly.
The moment he heard Garp’s voice— He turned around and ran.
Unfortunately for him, escape was impossible.
Garp instantly appeared behind Ace and grabbed him by the collar effortlessly.
“You little brat!
Why’re you running?!” Ace flailed violently.
“LET GO OF ME, OLD MAN!” Garp answered with a fist directly to Ace’s head.
Bonk.
A giant swelling instantly rose on Ace’s forehead.
Tears flooded Ace’s eyes immediately.
Kahn silently watched the scene from the yard without reacting.
Garp finally turned toward him.
Then the old marine paused slightly.
Kahn’s body had changed again.
Even at only three years old, the child stood unnaturally steady, almost like a miniature warrior rather than a normal boy.
The firmness of his muscles was especially shocking.
Garp narrowed his eyes subtly.
This brat… He was developing far too quickly.
“Kahn.” Garp tossed a bag of senbei toward Makino before speaking calmly.
“Pack your things.” “I’m taking you somewhere else.” Kahn did not ask questions.
He already knew the answer.
Mount Colubo.
The place where Garp trained Ace and later Monkey D.
Luffy like wild animals.
Without wasting time, Garp grabbed one child beneath each arm and headed toward the mountain forests beyond Foosha Village.
The deeper they traveled into Mount Colubo, the rougher the terrain became.
Dense weeds covered the narrow paths.
Wild beasts howled throughout the forest.
Ace instinctively grabbed Garp’s sleeve nervously.
Kahn, however, observed the surroundings with visible interest.
The air here felt completely different from Foosha Village.
Wilder.
More dangerous.
He could sense predatory creatures watching from deep within the forest shadows.
To Kahn, this place was perfect.
Eventually, an old wooden cabin appeared halfway up the mountain.
Without warning— Boom!!
Garp kicked the door open directly.
The wooden entrance shattered apart violently.
The people inside nearly jumped out of their skin.
A large woman with curly orange hair stood up abruptly while holding a chipped machete.
Curly Dadan.
The leader of the Dadan Family.
A mountain bandit with an eight-million-Berry-class bounty.
The moment she recognized Garp— Her hand trembled.
Clang.
The machete fell directly onto the floor.
“V-Vice Admiral Garp…” Even the bandits behind her turned pale instantly.
Dogra and Magra nearly collapsed to their knees from fear.
Garp casually threw Ace and Kahn onto the floor.
“Dadan,” he announced bluntly, “I brought you two new family members.” Dadan stared at the children in disbelief.
“THIS IS A BANDIT HIDEOUT, NOT A DAYCARE!!” “And we barely have enough food for ourselves already!” Garp calmly picked his nose.
“Oh?” His eyes suddenly sharpened dangerously.
“Then maybe I should drag you all to Impel Down instead.” Crack.
He clenched his fists casually.
The terrifying pressure in the room intensified instantly.
Cold sweat rolled down Dadan’s face.
She understood better than anyone how terrifying Garp truly was.
Against monsters like him, her bounty meant absolutely nothing.
“We’ll raise them!” Dadan shouted immediately.
“We’ll raise them properly!” Garp grinned in satisfaction.
“Good.” “If I hear they’re starving, I’ll flatten this entire mountain.” Then— Without even checking further— Garp turned around and left.
Just like that.
Silence filled the cabin afterward.
Dadan stared at the two children while clutching her forehead in pain.
Ace immediately pointed at her rudely.
“Hey, fat woman!” “I’m hungry!
Give me meat!” Veins bulged across Dadan’s forehead instantly.
“WHO ARE YOU CALLING FAT, YOU LITTLE BRAT?!” She looked moments away from exploding.
Then— Kahn quietly walked forward.
Without speaking, he approached a massive wooden water barrel sitting in the corner of the cabin.
The barrel weighed at least several hundred pounds when full.
Even grown adults struggled to move it properly.
Kahn crouched slightly.
Then lifted it.
Smoothly.
Steadily.
The water surface barely rippled.
The entire cabin froze.
Dadan’s jaw nearly hit the floor.
Dogra’s eyes widened so much they looked ready to pop out.
“How…?” “How is that possible?!” This was a three-year-old child.
Kahn calmly lowered the barrel back onto the floor.
Then he looked toward Dadan.
“I’m not picky about food,” he said quietly.
“But I eat a lot.” “In return, I’ll help hunt.” Dadan swallowed hard.
At that moment, she realized something horrifying.
What Garp had dumped onto Mount Colubo wasn’t a burden.
It was a little monster.
Life on Mount Colubo quickly became far more exciting than life in Foosha Village.
Kahn’s daily training intensity increased dramatically.
The mountain’s wild beasts became his natural sparring partners.
Wild boars.
Black bears.
Mountain wolves.
At first, Kahn could only dodge their attacks skillfully.
But over time, he gradually began fighting them directly.
Punch against claw.
Strength against strength.
Ace also trained relentlessly.
Although he lacked Kahn’s terrifying physique, Ace possessed incredible ferocity and natural combat instincts.
He fought like a starving wolf cub.
The twins frequently returned to Dadan’s cabin covered in bruises and cuts.
Dadan always cursed loudly while treating their wounds.
Yet somehow, she still secretly saved the best portions of meat for them.
Even mountain bandits could become attached eventually.
As time passed, Kahn gradually noticed something strange about his body.
At first, he assumed his breathing techniques were finally producing visible results.
But slowly, he realized the truth was far more absurd.
His physical strength was increasing far too quickly.
Even on days without intense training, his body continued evolving steadily.
Then Kahn finally discovered the pattern.
Sunlight.
Every time he stood beneath the sun, he could feel warmth flowing into his body continuously.
His skin absorbed sunlight greedily.
His muscles strengthened rapidly.
His bones became denser.
Even his senses sharpened.
He could now see the veins within leaves from over one hundred meters away.
He could hear worms moving beneath the soil.
Kahn became stunned internally.
Sunlight made him stronger?
This was practically Superman’s Kryptonian physiology.
Yet no such race or ability existed within One Piece lore.
Which meant— This ability likely came from his transmigration itself.
A cheat beyond the world’s rules.
To confirm the theory, Kahn conducted an experiment personally.
For three consecutive days, he remained hidden inside dark wooden shelters while continuing ordinary physical training.
His strength growth slowed dramatically.
Almost stagnating entirely.
Then on the fourth day— Kahn climbed onto the highest rocky cliff of Mount Colubo beneath the blazing noon sun.
Shirtless, he spread his arms outward.
Sunlight poured across his body.
Instantly— Warmth flooded every cell within him.
His exhaustion vanished completely.
It felt as though a miniature sun had awakened inside his body.
Kahn clenched his fist tightly.
Then punched the massive boulder before him with full strength.
BOOM!!
The rock cracked apart violently.
Fragments exploded in every direction.
Kahn stared silently at his own fist afterward.
He had not used Haki.
This was pure physical power.
And that was the terrifying part.
Within the world of One Piece, monstrous strength always required some explanation.
Garp forged his legendary fists through decades of hellish combat training.
Kaido possessed the bloodline of the Oni race alongside an overwhelmingly powerful Mythical Zoan Devil Fruit.
But Kahn?
He only needed sunlight.
As long as the sun existed— He could continue becoming stronger forever.
Without limit.
After discovering this secret, Kahn immediately changed his entire routine.
Nighttime breathing exercises remained important.
But daytime became sacred.
Every second beneath the sun increased his power.
The Dadan Family soon grew accustomed to witnessing bizarre scenes daily.
While everyone else desperately hid beneath shade during the hottest hours— Kahn laid shirtless in the center of open grasslands beneath the blazing sunlight with a peaceful expression on his face.
Dogra wiped sweat from his forehead while staring blankly.
“…Did this kid cook his brain under the sun?” Smack.
Dadan immediately slapped the back of his head.
“Shut up, idiot!” “That’s how monsters cultivate!”
