Rip!
As Chakra was infused, the Chakra paper in Naruto's hand split into two halves down the middle.
Naruto looked at the Chakra paper split in two in his hand, blinked, and immediately looked at Hiruzen Sarutobi with a curious gaze.
The knowledge barrier in the Ninja World is quite solid, with almost impenetrable walls from top to bottom. Chakra nature transformation is already knowledge at the Jonin level, and Jonin-level Ninja knowledge is almost never made available to those below. Therefore, apart from some Ninja from large clans, civilian Ninja hardly know what Chakra nature transformation actually is, which is also one of the reasons why few civilians become Jonin.
Besides bloodline, knowledge is also the foundation of Ninja clans.
Hiruzen Sarutobi chuckled and began to explain: "The paper splitting in two down the middle indicates that little Naruto's Chakra is Wind-style Chakra."
"Chakra is generally divided into five natures: Fire, Wind, Lightning, Water, and Earth. Different natures will show different reactions on the Chakra paper.
Fire: the paper will catch fire. Wind: the paper will split down the middle. Lightning: the paper will wrinkle. Water: the paper will get wet. Earth: the paper will crumble. If all five natures are possessed, then one area will catch fire, one area will be split open, one area will become wrinkled, one area will get wet, and the last area will crumble."
"So, is it stronger to have more natures?" Naruto asked innocently.
"Of course not. The nature of Chakra is just one way to use Chakra. If you possess the corresponding nature, you can convert neutral Chakra into the nature of the Ninjutsu you intend to use when you mobilize and refine it within your body. For example, if you want to use Fire Release, you transform neutral Chakra into Fire-style Chakra. This is nature transformation."
"But the most important prerequisite for performing the Five Element Release Ninjutsu is still the Ninja's own Chakra volume. If your Chakra volume is insufficient, even if you possess all five natures, it will be very difficult to perform Release Ninjutsu. Moreover, the nature of Chakra can also be cultivated and refined through later training."
"As for Chakra form transformation, it involves releasing Chakra externally and then controlling the shape of the Chakra to change. For example, the Rasengan you practice is the purest form transformation of externally released Chakra, compressing Chakra into a high-speed rotating sphere."
"So, little Naruto, what you are suitable for practicing now is Wind-style Ninjutsu."
"Grandpa Third, how do I transform the Chakra's nature?"
Naruto asked with an excited expression.
"Wind-style Chakra's most prominent feature is its cutting ability, possessing extremely powerful offensive capabilities."
Hiruzen Sarutobi casually picked up a fallen leaf from the ground, and as Chakra was released, the leaf was immediately cut into two halves.
"You just need to do this... and then that... when you can easily cut this leaf, you can learn Wind Release."
Naruto immediately picked up a leaf and tried, but after several attempts, he didn't succeed, and a troubled expression appeared on his face.
Hiruzen Sarutobi nodded naturally when he saw this scene. Mastering Chakra nature transformation is a long cultivation. Although he is now known as the Professor of Ninjutsu and can effortlessly use the Five Element Release Ninjutsu, it took him several years to completely master one Chakra nature transformation back then.
"Little Naruto, don't rush, you are still..."
Hiruzen Sarutobi's comforting words were cut short and stuck in his throat.
At this moment, Naruto was holding the leaf he had cut in half with Chakra, looking at him with a surprised expression and anticipation.
It was a joke. Something produced by the system, even if not a masterpiece, could not be a defective product. His reward at that time was Chakra mastery, which could be said to have directly saved him several years of cultivation time, allowing him to avoid several years of detours. Not only did he not have to worry about the interference of Nine-Tailed Beast Chakra, but he could even make his Chakra transform into whatever he wanted.
The reason he failed a few times at first was just to test Hiruzen Sarutobi. He just didn't expect his performance to be too genius. He had thought that Chakra nature transformation was not a difficult thing, after all, in the original work, Sasuke could spray fire at the river when he was five or six years old. So he tried a few times and then directly showed success.
Hiruzen Sarutobi swallowed with some difficulty, forcing out a smile.
"It seems little Naruto's talent is quite good."
Fortunately, Naruto's fire will was pure enough, and he cared about the villagers, otherwise he would not have felt at ease letting Naruto learn Ninja knowledge so quickly.
Thinking of this, Hiruzen Sarutobi's face showed a satisfied smile again.
And feeling the change in Hiruzen Sarutobi's malicious thoughts, Naruto's heart also couldn't help but skip a beat. After finally calming down, he also secretly breathed a sigh of relief, after all, this meant he wouldn't have to become a rogue Ninja at such a young age.
"Grandpa Third, can you teach me new Ninjutsu now?"
Naruto blinked his big eyes, looking up at Hiruzen Sarutobi with a face full of desire.
Hiruzen Sarutobi smiled and extended his withered palm, stroking Naruto's head. The calluses on his palm scraped Naruto's scalp, causing pain.
"Little Naruto, the Ninjutsu you have mastered so far are all close-range offensive methods. Since that's the case, little Naruto, please step back. Today, Grandpa Third will teach you a long-range Wind-style Ninjutsu."
Naruto quickly retreated a few steps. Hiruzen Sarutobi was already standing in place, slowly forming three hand seals towards the gently flowing river.
"Wind Release: Vacuum Bullet!"
Chakra quickly gathered in Hiruzen Sarutobi's mouth. He immediately exhaled a breath towards the river, firing the accumulated Chakra in his mouth like a bullet. Immediately after, he continuously exhaled several short breaths, firing like a machine gun.
The Vacuum Bullet quickly landed on the river surface. The flowing river immediately splashed large amounts of water, and the calm lake surface instantly became riddled with holes. The formerly slow-moving lake suddenly became turbulent until it filled the large pits at the bottom of the river before becoming calm again.
"So, so amazing."
Naruto's eyes sparkled.
"All right, little Naruto, I'll explain this Ninjutsu to you now."
Hiruzen Sarutobi explained the three hand seals required for this Ninjutsu in great detail to Naruto. Although it was a B-rank Ninjutsu, it wasn't very complicated because it had fewer hand seals. The main factors were Chakra volume and proficiency.
Uzumaki Naruto quickly learned this Ninjutsu. He walked to the river, adopted the stance Hiruzen Sarutobi had used earlier, and then, pretending to be clumsy, formed three hand seals with great awkwardness.
"Wind Release: Vacuum Bullet!"
A large amount of Chakra gathered directly in Naruto's mouth, and he forcefully sprayed it towards the river.
However, the result was all bark and no bite. Although a large amount of Wind Release Chakra had gathered, the Vacuum Bullet released was only the size of a marble, slowly drifting towards the river. After it disappeared into the water, it only caused a small ripple.
Naruto's small face visibly fell.
"Haha, it's alright, little Naruto." Hiruzen Sarutobi came to Naruto's side and placed his hand on Naruto's small head again.
"It's already very good to successfully release a Ninjutsu for the first time. Just practice diligently."
"I will practice hard." Uzumaki Naruto's eyes were incredibly resolute.
"Mhm, Grandpa believes in you." Hiruzen Sarutobi looked at the sky; the sun had already fully risen.
"Since that's the case, little Naruto, you must also pay attention to safety when you practice by yourself. Grandpa has something to do, so I'll leave first."
"Mhm, goodbye, Grandpa Third," Naruto said with some reluctance.
"Naruto, I'll come to see you again when I have time."
Hiruzen Sarutobi smiled and then used the Body Flicker Technique to disappear from the spot.
Looking at the spot where Hiruzen Sarutobi disappeared, the smile on Naruto's face did not diminish in the slightest. Feeling the Anbu hidden in the shadows, the smile on his face became even brighter.
Today was a good day.
