After more than ten minutes, Kairen finished his final ten thousand frog jumps.
He collapsed to the ground, utterly exhausted. The Senju Clan cells within him, together with the Nine-Tails' chakra, began repairing the fatigue in his body.
Seeing this, Scholar waved his hand.
"Executioners, get ready!"
A shadow clone holding a massive axe stepped forward and, without a word, brought it down — chopping Kairen's head clean off.
When Kairen resurrected, he stared wordlessly at Scholar.
Scholar explained, "This way's faster. Your main body's pain receptors are already numbed. Get up. This time, we're training speed."
Kairen nodded. This Scholar clone was cold and logical — his absolute rationality.
"Multiple Shadow Clone Technique!"
As soon as Kairen stood, he clapped his hands together and created fifty shadow clones.
They quickly tidied up the ground, building a fifty-meter running track.
Once it was done, the clones lined up beside Kairen to practice speed together. Kairen needed their feedback to refine his own burst-speed techniques.
One clone held a gun skyward.
"Ready!"
About fifty clones stood side by side at the starting line. Kairen's muscles tensed, his eyes narrowing in concentration.
Scholar held a stopwatch and said, "Use your full power. I need to know your limits so I can plan the next stage of training."
Kairen nodded, sinking low, growling softly.
"Rrraaah—!"
In an instant, four chakra gates burst open. Green energy swirled around his body, followed by a layer of Tailed Beast chakra forming a cloak.
Kairen had activated his full-power chakra mode!
The clone with the gun raised it like a referee and shouted,
"Go!"
Bang!
"Hey! Why'd you shoot me?!"
Kairen vanished in a blur, leaving only a streak of red light in the air and a cloud of dust in his wake.
The clones were stunned, choking on the dust behind him. Scholar kicked two of them to get moving, and they finally sprinted forward in proper formation.
When Kairen stopped, Scholar walked up to him and checked the stopwatch.
"0.2 seconds!! That's your full-power mode. Now try again — no chakra this time. Just pure physical energy."
Kairen nodded, his eyes flicking to the side.
"If we're talking about taijutsu experts in the village, that would be Might Duy and Guy. I'll send a clone to train under them and collect experience."
Scholar nodded. "Both of them are taijutsu masters — top-tier in physical movement and body control."
"Hahaha! My youth is finally here!"
A clone jumped out, forming hand seals.
Poof!
His gray short-sleeved shirt instantly turned into a green jumpsuit. His hair became a bowl cut, his eyebrows thick, and the forehead protector on his head now bore the word [Youth].
His voice brimmed with spirit.
"My youth will never fade!"
Even the chakra vibrations from his body formed a rhythmic tune:
"You exist~ deep~ in my mind~~"
With sparks of passion bursting in his heart, the clone burned with excitement.
"I'm on fire!"
"I'm on fire too!"
"I feel like I could ignite the entire Boruto series!"
The surrounding clones got worked up too — the air thick with hot-blooded youth.
Youth Mode, activated.
Kairen kicked the Guy clone in the butt.
"Cut it out! Change back — you're ruining my image."
Guy-Kairen gave a thumbs-up, his teeth gleaming with a white flash.
"But this is the taste of youth!"
Kairen ignored him. If he ever got a bowl cut, thick eyebrows, and wore a green jumpsuit, Tsunade and the others would revoke all mating privileges on the spot.
"If you insist on transforming, at least cover your head!"
Kairen formed a quick hand seal and forced Guy-Kairen to transform.
In an instant, the clone's outfit changed — red and blue skintight suit, web-like patterns, a black spider emblem on the chest, and a red mask over the head.
If that wasn't Spider-Man, what was?
Kairen laughed.
"See? Much cooler. Covers your face, hides the haircut and eyebrows. You can even play Peter Parker now. From now on, your name's Peter Kairen."
Peter Kairen's voice was filled with excitement.
"Sure, sure! It's still a tight jumpsuit, still full of youthful energy — same thing!"
"From today on, I am Spider-Man!"
He turned toward Snake Doctor and shouted,
"Doc! Remember to develop a Spider Ninjutsu based on Kidōmaru's techniques from the Sound Four! The little spider of the ninja world is about to debut!"
Snake Doctor flicked his tongue.
"Understood!"
Peter Kairen's figure flashed away, off to train in taijutsu with Guy and Might Duy.
Watching him leave, Kairen couldn't help but think — Spider-Man's here already. Could Iron Man and Thor be far behind?
The Ninja World's Avengers might soon assemble… would he be the one-eyed Nick Fury leading them?
Scholar, seeing Peter Kairen leave, approached Kairen with a clipboard.
"There are still plenty of training modules left. The main body should pick up the pace!"
Kairen nodded and resumed his high-intensity training.
Ding!
"Your shadow clone Snake Doctor has successfully developed a new jutsu!"
Ding!
"Firearm weapon 'AK-47 Automatic Rifle' successfully recorded!"
Kairen froze, turning toward the Revolutionary and Deidara clones.
He saw the Revolutionary clone holding a black-and-orange automatic rifle, repeatedly pulling the trigger — red flashes bursting from the muzzle.
"Hahaha… now this is the weapon of the people!"
The AK-47's bullets were a miniaturized form of the Fire Gun's projectiles — renamed Fire Dragon Bullets. The explosions were removed, replaced with more wind-element Chakra Nature Transformation to increase penetration power.
Deidara's clone grabbed one too, firing wildly into the sky.
"This is true art!"
Kairen shouted,
"Bring it over — I want to test the power!"
The two clones ran over. The Revolutionary clone pressed the muzzle against Kairen's forehead.
"Perfect! No need for human testing anymore!"
A wheelchair materialized behind Kairen. He sat down, exuding the aura of a dark god.
The surrounding clones were shocked.
"Fiery Cloud!"
"I almost forgot that title!"
"Is he really gonna catch bullets with his hands?!"
"Terrifying!"
Kairen crossed his legs, a lazy grin on his face.
"Shoot."
The Revolutionary clone raised the gun.
Another clone used chakra to simulate background music for this legendary scene.
All the clones dropped to one knee.
"Welcome back, Fiery Cloud!"
Bang!
A burst of flame erupted — the Fire Dragon Bullet tore forward.
Kairen lifted two fingers, smiling.
"All martial arts under heaven — unstoppable, unbreakable — speed conquers all!"
The bullet pierced through Kairen's skull. He collapsed instantly.
Ding!
"You have been killed by your shadow clone using a firearm weapon. Experience +30!"
The clones dispersed. The one who had been playing background music switched to the Great Compassion Mantra.
A few clones conjured suona horns, drums, and cymbals — playing a festive funeral tune.
"La~ la~ la~"
Kairen resurrected again, blinking in surprise. Getting shot by an AK for self-kill XP gave quite a boost.
He was hooked instantly.
"Again! A few more rounds — I'll max it to 100 points!"
"Roger that."
Kairen was shot dead several more times by the Revolutionary clone until he had maxed out his experience — replenishing the 100 points he'd previously lost.
