The next day.
Jokichi went to the academy early in the morning to ask Iruka for a long leave of absence.
And Iruka did not even ask for the reason and directly approved it.
He smilingly patted his shoulder and encouraged: "The teacher's level is limited and I cannot teach you too much, so go do it with peace of mind. Perhaps, the teacher will feel proud of having taught you in the future."
Hearing this sentence, Jokichi immediately understood that his plan had succeeded.
He did not hesitate, directly bidding farewell to Iruka, and then left to begin formal ninjutsu training.
Of course, he did not choose the Ninth Training Ground next to the academy, but went to the 39th Training Ground he used to frequent.
After all, advanced ninjutsu could already be considered a ninja's main power and trump card. It could not be casually shown to others, so naturally, he could not choose a crowded place to train.
To prevent the previous performance from being exposed, Ryohei would also come to the scene.
Of course, as a former Anbu squad captain, it was more than enough for him to give the current Jokichi some training guidance.
It could not be considered entirely just to put on a full act!
With everything prepared properly, Jokichi trained in ninjutsu with peace of mind.
However, he did not directly proceed with the chakra nature transformation training, but learned the Shadow Clone.
A physical clone created by equally dividing one's own chakra, possessing the same personality and independent consciousness. It will automatically dispel when receiving an attack exceeding its limit, or it can be actively dispelled by oneself.
All the experiences, sights, and feelings the clone goes through will return to the main body along with the chakra after the clone is dispelled.
Because the clone equally divides chakra, it carries risks and is designated as a forbidden jutsu by the village. Only those whose chakra meets certain requirements can learn it.
After all, chakra is refined from spiritual energy and physical energy, and is related to a person's life. Complete exhaustion of chakra leads to death.
For people with little chakra to practice it, a single mistake could cause the risk of all chakra draining away.
But conversely, for people with a lot of chakra, this is a godly skill with various uses.
When busy, one can have shadow clones do different things at the same time. During battle, one can use shadow clones to test the enemy's abilities.
And for people with a lot of chakra and a fast recovery speed, it can also be used to learn skills, just like using a cheat.
However, the fatigue and stress this training method causes to the body and mind are too great, and ordinary people cannot bear it.
In the anime, with Naruto's conditions, he collapsed from exhaustion every day.
After persisting for a month or two and completing the training, he never used a similar method again.
Jokichi had the Perfect Sage Body and the Ring of Kurama. Whether it was chakra volume or recovery speed, few could match him.
Although his Sage Body had not reached its peak chakra because of the short time he had obtained it and his body not having fully developed into adulthood.
But for training, it was already enough.
He read through the scroll once to understand the usage method of the Shadow Clone.
Then he asked Ryohei about some parts he did not understand.
With the enhancement of the Top Student Glasses and the Hat of Wisdom, he instantly understood the principles and training methods.
Then...
Shadow Clone Jutsu.
He formed hand seals with both hands and silently chanted in his mind.
As chakra was mobilized, Jokichi felt a massive amount of chakra being separated out of his body.
"Poof, poof, poof, poof..."
Accompanied by bursts of sounds and smoke, forty or fifty identical clones appeared in the forest.
"Th-This..."
Ryohei, watching from the side, opened his mouth but could not speak for a long time.
This was no longer the Shadow Clone, but the Multiple Shadow Clone.
Although it is the same jutsu, depending on the usage method, the resulting consequences and impacts are completely different, and the rank of the jutsu is also separated because of this.
The Shadow Clone is only a B-rank ninjutsu, while the Multiple Shadow Clone is an A-rank ninjutsu. Whether in terms of power or learning difficulty, they cannot be mentioned in the same breath.
Succeeding on the first try, and even bringing out the advanced version.
Jokichi also smiled proudly.
However, he also knew that the Shadow Clone ninjutsu was very easy to learn for people with a lot of chakra.
He felt the remaining chakra in his body; only one-fiftieth was left, which was only four times more than Ryohei's.
In other words, Jokichi's current chakra volume was 200 times that of an ordinary Jonin.
He did not know whether Kakashi's chakra volume was more or less compared to a normal Jonin.
Although he was famous for having little chakra.
But Lu Xun once said: The main characters in any work possess no reference value.
Jokichi deeply agreed with this.
If one could use main characters for comparison, wouldn't all the Genin in the world be at the same level as Naruto and Sasuke?
Therefore, Jokichi could not judge whether his chakra was more or less compared to Naruto at that time.
However, it should be much less!
After all, Naruto used hundreds of shadow clones when training back then.
While he himself, after splitting fifty, only had this little chakra left.
He simply could not train recklessly like Naruto did.
But Jokichi was not in a hurry either.
He was only over seven years old now, so it was normal not to compare to Naruto when he was fifteen.
Although his Sage Body could not compare to his own, he still had the Nine-Tails as a power bank charging him for fifteen years, and it was the kind that charged to the maximum limit.
Therefore, he could not be underestimated either.
"Mhm, since the Shadow Clone is learned, let's start learning the chakra nature transformation!"
Jokichi nodded in satisfaction and dispelled the Shadow Clone Jutsu.
The separated chakra returned to his body, bringing along fifty different experiences.
The scenes seen by each vision, the feelings touched upon...
The sudden addition of fifty times the information processing made his brain feel as if it had been stuffed with countless garbage, resulting in a splitting headache.
"Just this short while, and haven't even done anything, and it is already like this?"
Jokichi felt dizzy, his body swayed, and he was caught in time by Ryohei.
"This is because it is your first time using it." Ryohei smiled wryly. "Ordinary people cannot split so many clones at once, there is a gradual adaptation process."
"I-Is that so."
Then what was the deal with Naruto?
Having thick nerves, causing his brain to automatically ignore the details?
Jokichi held his head with one hand, and was supported to sit on the ground with the other. He calmed his mind and only recovered after a good while.
He let out a deep breath and lamented inwardly: As expected, anime is anime, and there are still some differences from reality.
Just like how Fire Release cannot kill anyone in the anime, while Ryohei told him that Fire Release is the most lethal ninjutsu with the widest area of effect and highest efficiency for killing enemies.
At first, he was still somewhat skeptical, but now he completely believed it.
Therefore, next, the chakra nature transformation training also shifted from hesitating between Wind and Fire, to Fire.
After all, fire is very handsome, and it is not flashy without substance like in the anime, so he definitely had to choose it!
Because they did not know if the Third Hokage was peeking, the two still performed the act of a good teacher instructing his beloved disciple once.
Then the formal training began.
Holding an ordinary piece of paper in his hand, he outputted chakra with the thought of burning it.
And then...
There was no reaction at all.
Mhm! Today is also a peaceful day!
