Naruto: Start by chopping down a tree and shocking Kurama!

Ever since Naruto learned how to refine chakra, he still comes to the grove by the river to pound trees every day.

After doing this for several days in a row, he was almost getting into the habit.

When I woke up in the morning, before I was fully awake, my body automatically walked to the grove by the river.

When he woke up, he found himself going bang, bang, bang.

It’s a pity that I haven’t yet mastered the art of clone-art.

When I watched anime in my previous life, I saw ninjas using clones with ease.

But when it was really my turn to practice, I found that I not only had to remember the chakra flow routes in my body, but also had to control the output of chakra.

Using too much or too little chakra will affect the success rate of the technique.

The one with the greatest impact was the big fox in the sealed space...

Although Kurama restrained his chakra, some of the red chakra was still mixed with his blue chakra.

This resulted in Naruto's original input of chakra being just right...

As a result, Kurama's chakra was always pulled in from time to time.

It was because of this that the last few times Naruto used the clone jutsu, the clones that appeared were completely broken off and had no consciousness at all.

It’s even more miserable than what Naruto created in the original story.

After a few times, Naruto learned his lesson and deliberately reduced his chakra output…

But that red chakra is very uncontrollable!!

Sometimes there is, sometimes there isn't...

He now understood why Naruto in the original story had such a hard time...

The big fox may not have been causing trouble on purpose.

It's simply because the tailed beasts have too much chakra. Even a little bit of chakra leaked is enough to disrupt the chakra of an adult ninja.

He was able to use ninjutsu in this situation, even if he failed, it was quite remarkable...

Naruto thought so to comfort himself, but still expressed some dissatisfaction towards the big fox.

The vixen in my stomach has been laughing since I was practicing the art of splitting myself into two, and it hasn't stopped at all!

Naruto listened to the mocking voices in his ears, and looked at the upper body and lower body of the clone on the ground, and he couldn't bear it anymore.

"Big fox! Can you please stop laughing!"

"It's because you bothered me that I couldn't succeed!"

"Hahahahaha!"

"I have never seen such a funny clone!"

The fox ignored Naruto and laughed wildly at the top of his lungs.

Naruto was so angry that he started practicing the clone technique out of spite.

Anyway, I have enough chakra to practice for a day and a night!

In his previous life, he could work on a plan for days and nights, so he didn't believe that he couldn't come up with a small clone technique!

Then, the sound of "bang bang bang" of clones appearing and disappearing kept appearing around.

Naruto also experienced failure again and again.

When Kurama in the sealed space saw how hard Naruto was trying, he stopped mocking him.

The thousandth time, he finally created a slightly more normal clone...

Although it looks like a mini version of myself, I am getting closer to success.

He then performed the clone seal five thousand times. At the five thousand and first time, Naruto felt a sudden flash of inspiration in his mind and he suddenly understood.

Since the tailed beast chakra will interfere with me...

And the clone technique requires a fixed amount of chakra...

Then I can calculate the fixed chakra amount, and then calculate the variable chakra of the tailed beasts. Finally, the sum of the two can reach the chakra of the clone jutsu, right? !

The scroll given by the old man from the third generation did not specify how much chakra was needed to operate the clone.

It just tells about the routes in the body, the hand seals, and the purpose of the clone, and that's all.

If you want to learn a ninjutsu, you have to keep trying until you find the minimum amount of chakra required to operate this ninjutsu.

Isn’t this pure empiricism?

Naruto felt that most of the ninjutsu in the ninja world might be like this, basically just like "I'm thinking"!

Those ninjas who tried to learn ninjutsu were completely through a process of trial and error, and those who succeeded less often were called geniuses.

It is no wonder why Naruto in the original work taught Konohamaru ninjutsu in that way.

Konohamaru is truly a genius to be able to learn this.

The overall feeling is like a little salt in a recipe, or like the abstract description of various martial arts in martial arts novels.

The main focus is on abstraction.

"Big fox!"

"Is there any unit for chakra?"

Although in the anime, Kakashi compared himself to Naruto, and was later called the unit of chakra measurement.

In fact, everyone is just playing with memes, and this behavior is also empiricism.

Naruto was afraid that Kurama wouldn't understand, so he changed to a simpler way of saying it.

"It's... something that calculates chakra."

"For example, how much chakra is needed to create a clone."

When Jiu Lama heard this strange question, he was subconsciously stunned.

What do you want this thing for?

Anyway, its chakra is endless, so why would it think about this?

However, Kurama began to recall the situation of Hashirama and Madara, as well as all the ninjas he had met, and finally found that no one cared about this issue at all.

"What do you want this for?"

"I have never seen anyone care about this."

Okay...

The case is solved!

After Naruto realized this, his expression became very strange.

The ninja world has been developing for at least a thousand years, right?

Why haven’t we unified the standards?

No wonder there has been no progress at all.

In the later period, he was pinned to the ground and beaten by the Otsutsuki clan, and it was really fair that he lost.

No!

Now that he knew this, he had to work out the chakra standards first.

In this way, when you learn ninjutsu in the future, you can learn it quickly by just trying little by little according to the fixed amount.

With chakra units, standards can be set, which is equivalent to making the practice of ninjutsu more data-based.

It's probably many times better than the feeling I have now.

After thinking it through, Naruto stopped practicing the clone technique and went back to lie down in front of the tree.

Kurama was still wondering what this kid was doing, and then he saw Naruto appear in the sealed space.

"How can I do this well..."

Naruto stroked his chin, wandering around the orchard while thinking.

When I passed by an apple tree, I found a fruit right next to my mouth, so I took a bite.

Quacking, quacking——

He chewed the fruit, raised his head at a 45-degree angle to look at the sky and began to think.

Suddenly, Naruto's eyes stopped on the light on the top of the sealed space.

"I understand!"

"The number of light bulbs can be used as a unit to measure chakra!"

The lights in the system interface, including all lighting props in the module, and props that require energy to drive can be used to do this.

Because for these props, there is no mandatory need for electricity or anything like that, as long as there is energy, it will be fine.

Logically speaking...

Chakra should also be a kind of energy, right?
