Chapter 93: Watch Carefully! Learn Carefully! I'll Only Teach You Once!
Inside Konoha's Forest of Death.
BOOM!!
An adult-sized boulder took a heavy hit, the exploding gravel scattering in all directions.
Uzumaki Naruto stood his ground, eyes calm, arm extended forward, aimed at the gravel flying towards him.
Without needing hand seals, Wind Release Chakra flowed through his body with ease.
Colorless wind blades slowly condensed in Naruto's palm; one could faintly hear the piercing whistle of the wind blades.
"Wind Style: Wind Blade!"
As his voice fell, countless wind blades shot out.
Swish! Swish! Swish!
The fine gravel before Naruto was struck with extreme precision by the wind blades, turning into stone dregs that slowly drifted down.
But witnessing this scene, Naruto sensed the chakra he had consumed and couldn't help frowning.
"Although there's progress, my chakra control level still isn't good enough."
A week ago, he still couldn't balance chakra output and control, but now he could already precisely shatter all flying stones in one go.
Recently, Naruto had begun practicing even finer chakra control.
This was necessary training for chakra shape transformation and nature transformation.
"Wonder when I'll be able to use a Wind Release Rasengan..."
Naruto extended his palm; chakra could be faintly seen gathering there.
With a thought, the chakra in his palm began to rotate.
But when Naruto attempted to add Wind Release chakra, the chakra sphere abruptly dispersed.
A whirlwind scraped around him, cutting small wounds on Naruto's body.
In the blink of an eye, they healed rapidly, blood not even having time to flow out.
"Let's continue with today's handicraft homework."
Naruto shook his head with a wry smile, then sat down on a nearby stone platform.
Picking up a piece of wood from the side, he condensed a small wind blade with his fingers and began carving.
Behind him, a pile of bizarrely shaped scrapped items was already laid out.
But just as Naruto was about to start,
"Naruto!!"
A voice tinged with slight resentment came. A hint of helplessness also appeared on Naruto's face.
BOOM!!
Naruto effortlessly reached out and caught something, then turned to meet Sasuke's eyes.
Bang bang bang!!
The two didn't waste words, directly engaging in battle.
However, Sasuke only held the upper hand at the very beginning. In this kind of high-intensity taijutsu battle, his chakra and stamina quickly bottomed out.
Naruto's breathing, however, remained steady as he effortlessly caught Sasuke's attacks.
BOOM!!
"Ugh..."
Then Naruto punched Sasuke in the stomach, directly making Sasuke's body go limp, kneeling on one knee, retching for a good while.
"Sasuke, that's about enou—"
"I haven't lost yet!"
Naruto was just about to end the battle, but Sasuke suddenly got up and attacked him again.
"Sigh~"
Naruto's eye twitched as he let out a long sigh.
And so, Sasuke got beaten up for the entire day.
Only when the sun began to set did the two sit by a campfire, each holding a roasted rabbit leg, feasting heartily.
"You bastard, you actually use Shadow Clones to attend school?"
Sasuke's originally fair and handsome face was now bruised and swollen, looking quite miserable.
But he took a bite of rabbit leg, cheeks puffed out like a bun, questioning: "We agreed to train together, yet you secretly did extra training!?"
Sasuke had been wondering why Naruto was so quiet at school these past few days, wondering if something happened at home.
But he was a bit too embarrassed to ask, so he thought of secretly following him to check things out.
Only to see "Naruto" directly disappear before his eyes.
"Damn it! So Shadow Clones can be used like that!"
Sasuke opened his mouth wide in annoyance, angrily biting into the rabbit leg.
Ever since being defeated by Naruto, to surpass him, Sasuke had also been undergoing high-intensity taijutsu and ninjutsu training.
Although he always failed, Sasuke didn't give up, instead becoming more courageous with each setback, generating even stronger motivation to train.
However, he never expected this detestable fellow to be secretly doing extra training!
"And you call yourself a friend! Damn it!"
Naruto faced Sasuke's indignation, his expression unchanged.
He stated righteously: "I told you to learn the Shadow Clone Technique before, but you didn't want to, insisting on learning Fire Release ninjutsu. Can you blame me for that?"
Hearing this, Sasuke's expression instantly froze.
Naruto... did indeed tell him.
But he hadn't paid it any mind.
Awooo!
Sasuke ate resentfully, only able to suffer in silence.
Simultaneously, he resolved that when he got back this time, he would ask his brother to teach him the Shadow Clone Technique.
"You... were doing those handicrafts again just now?"
After a moment of silence, Sasuke changed the subject: "Are those handicrafts really useful for training?"
Naruto smiled upon hearing this, simultaneously raising his left hand.
Although he didn't form any hand seals, Sasuke saw an airflow rotating and flowing in Naruto's palm.
It looked incredibly obedient and well-behaved.
"You've already trained your Wind Release chakra nature transformation to this extent?"
Sasuke said with a shocked expression: "Just by doing those handicrafts?"
Transforming chakra into wind nature without hand seals – this meant his chakra nature transformation was trained to a very high level.
Some Konoha Jōnin couldn't even reach this standard!
"Of course, not just through carving."
Naruto shook his head: "The main purpose of carving is to allow me to cultivate my temperament while cultivating my body."
Cultivate temperament?
"Starting with that inexplicable stuff again."
Sasuke curled his lip, losing interest in this training method.
"I heard the Uchiha clan's shuriken manipulation technique is very strong."
Hearing Naruto's praise, Sasuke's head instantly lifted proudly.
However, Naruto's tone shifted, saying with a smile: "Why don't you teach me shuriken manipulation, and I'll teach you chakra nature transformation?"
"Alright."
Sasuke didn't think much, directly nodding in agreement.
Just now was only taijutsu sparring; neither of them used ninjutsu.
Of course, if they had, he would have lost even more miserably.
Meanwhile, in the seal space.
"Burp!"
The Nine-Tails, sprawled in its cage, patted its belly and exclaimed in amazement: "If I remember correctly, this brat is only 7 years old now, right?"
It had gone from being skin and bones at the beginning to its current chubby-cheeked fox state.
During this time, watching Naruto's progress, it had already grown numb to Naruto's talent.
Moreover, he also had Wood Release, Sharingan, Adamantine Sealing Chains...
Thinking this, the Nine-Tails' lip twitched, a wave of frustration in its heart.
Where is this a human brat?
Isn't this the Tailed Beasts' Big Daddy?
Realizing it had no chance of escaping the seal, the Nine-Tails instantly sprawled out even more comfortably.
"What was that phrase again?"
The Nine-Tails picked its teeth with a claw, murmuring: "Oh right! Walk to where the water ends, and sit to watch the clouds rise?"
It had heard the brat Naruto muttering it often during this time, so it had learned some too.
"Kurama, if you want to slack off, just say so. No need to drag out poetic verses."
A familiar voice suddenly sounding in the seal space made the Nine-Tails' eyes widen instantly.
At some unknown point, a figure had appeared within the seal space.
Still that familiar smile, still that familiar figure.
"Menma? Wait!"
The Nine-Tails' face couldn't help showing joy, but after sensing the pupil power in Menma's right eye, it froze.
"You... your eye?"
Is this a three-tomoe Sharingan?
But this pupil power... why does it feel so evil?
"Brat, don't tell me you've been..."
Seeing the Nine-Tails' hesitant look, Menma smiled helplessly.
Immediately, two golden chains extended from behind him.
Smack! Smack!
"Awooo!"
Even with the Nine-Tails' thick hide, its rear end was whipped raw, making it cry out in pain.
This familiar feeling, this familiar scent...
"Alright, alright! I know it's you!"
Seeing Kurama start to beg for mercy, Menma finally retracted the chains.
"Never mind my eye for now."
Then he asked as if nothing happened: "The principles of nuclear fusion reaction and fission chain reaction I asked you to learn – how's that going?"
Nuclear fusion reaction principle?
Fission chain reaction principle?
The Nine-Tails froze, then, snapping back, its eyes darted around as it said guiltily: "Should be... about there... maybe?"
It had indeed studied the notes Menma left.
But after so long, it had long since returned them to Menma (i.e., forgotten).
"Is that so?"
Menma raised an eyebrow.
Although he saw through Kurama's guilt, he didn't expose it directly.
Instead, he asked: "What's the difference between an atomic bomb and a hydrogen bomb?"
The Nine-Tails' eyeballs darted around. Racking its brains, it said: "Er... the explosion principles of atomic bombs and hydrogen bombs are different."
"Atomic bombs mainly explode using the fission chain reaction principle of heavy atomic nuclei like Uranium-235 or Plutonium-239, while hydrogen bombs mainly explode using the nuclear fusion reaction principle of hydrogen isotopes Deuterium and Tritium."
This it remembered clearly because it was on the first page of the notes.
Ordinary explosives burn substances like coal and oil.
Then, through the chemical reactions produced by the burning of elements like hydrogen, oxygen, and carbon, immense destructive power is generated.
But the atomic nuclei of these elements remain unchanged; what changes is only their arrangement.
An atomic bomb, however, doesn't work through chemical reactions, but through atomic reactions.
What changes are the atomic combinations of various elements, and the atomic nuclei.
The explosion after nuclear fission produces shockwaves and radioactive elements, etc. Its power is countless times greater than that of ordinary explosives.
And although a hydrogen bomb, like an atomic bomb, is a nuclear weapon, also works through atomic reactions, and also produces light/heat radiation, shockwaves, and other radioactive elements,
The explosion principle of a hydrogen bomb is still somewhat different from an atomic bomb's; it's not as simple as just nuclear fission.
"A hydrogen bomb first undergoes nuclear fission, then nuclear fusion, but but..."
The Nine-Tails' words paused, an embarrassed look on its face.
Menma didn't mind, adding: "But nuclear fusion requires a very large trigger. Generally, nuclear fusion can only be completed in an environment of tens of millions of degrees Celsius. An atomic bomb explosion creates a high-temperature, high-pressure environment, which then meets the prerequisite trigger condition for nuclear fusion."
Only then can the atomic nuclei of elements like hydrogen isotopes Deuterium and Tritium be ignited, releasing immense energy through a thermonuclear reaction.
"In other words, the atomic bomb is the detonator for the hydrogen bomb. The hydrogen bomb's explosion is based on an atomic bomb's explosion."
Stumbling through the explanation, the Nine-Tails finally let out a sigh of relief.
It then looked at Menma with a smug expression.
But Menma's smile remained unchanged as he asked gently: "Is that all?"
Emmmm...
The Nine-Tails' expression instantly froze.
Could it be... there's more?
"Sigh, didn't you want to learn my Rasenringu technique?"
Menma helplessly patted his forehead: "You sit properly. I'll only teach you once."
