Naruto, what kind of Hokage would you be if you didn't roll around!

"How far it can fly depends on the altitude and initial velocity..."

"Taking this question as an example, if you, as a ninja, stand at a height of 5 meters and throw a shuriken with an initial horizontal velocity of 100 meters per second, how far will it eventually land?"

Naruto Uzumaki: "...Aba aba aba..."

"What the heck! I can't understand a word of it!"

[Host, please listen attentively and learn carefully, otherwise you will be subjected to a baptism of lightning from the system...]

[Warning, countdown 5...4...3...2...]

"Ahhh, I get it!"

Naruto rubbed his cheeks vigorously, forcing himself to fully immerse himself in the task once again.

"If a shuriken is thrown forward with an initial horizontal velocity of 100 meters per second, what is the final distance it will travel..."

"Uh-huh……"

"Aha! I get it! At 100 meters per second, a few seconds of flight means hundreds of meters!"

"The question is, how many seconds can it fly?"

Iruka's gaze swept across the entire classroom, clearly intending to find a lucky person to answer the question.

The classroom instantly became tense, with everyone falling silent.

Iruka sighed and said helplessly, "Sakura, you answer this."

"Yes, Iruka-sensei!"

Sakura Haruno confidently stated, "To calculate the final distance, we need to multiply the initial horizontal velocity by the flight time. The flight time is determined by altitude. Considering that the gravitational acceleration in the ninja world is approximately 10, it's quite obvious that..."

She spoke eloquently, leaving most of her classmates completely bewildered.

Naruto Uzumaki, of course, didn't understand either.

However, unlike before, this time he forced himself to listen attentively, even if it was like listening to gibberish. With snot and tears streaming down his face, he tried his best to widen his eyes and open his ears, carefully listening to every word that Sakura Haruno said...

at this time.

[Your initial focused attention during the lecture has improved your understanding of the [Physics] subject. Proficiency +3, current proficiency level 28!]

Naruto Uzumaki was stunned for a moment, then overjoyed!

"This...this is possible?!"

Chapter 3 Naruto has gotten hooked on studying?!

Although he had just been electrocuted and was burning hot inside, Naruto heard a notification from the system.

Has your proficiency in physics improved?

Although I don't quite understand the exact meaning, there's no doubt...

It upgraded itself!

Naruto rubbed his eyes hard, widened them again, and looked at the incomprehensible writing on the blackboard.

This time, the effect was immediate and outstanding...

I still don't understand!

but……

I think I understand now!

"Could I really be a genius?!"

Naruto chuckled awkwardly, a sense of smugness welling up inside him.

however……

[The system has detected that the host has broken out of a state of complete concentration while studying and is about to receive a baptism of lightning from the system...]

[Warning countdown: 5...4...3...]

Uzumaki Naruto: "..."

Having learned from his experience this time, he didn't slack off at all and immediately forced himself into a learning state.

Iruka-sensei smiled slightly: "Very good, Sakura, as expected of the class's top student."

Sakura was equally smug.

"Did you see that, Sasuke-kun?"

Sasuke remained expressionless.

Sakura had no choice but to sit back down.

"Sakura..."

Naruto Uzumaki witnessed this scene and was about to express his sorrow when suddenly...

[Warning countdown 5...]

Naruto Uzumaki: "...Height, initial velocity, gravitational acceleration..."

What was originally an ordinary lesson now seemed to Naruto as terrifying as being imprisoned in an Anbu prison and subjected to severe torture!

Attending class is like going to a funeral!

Those mere forty-five minutes became the longest stretch of time in Naruto's life...

Focus your mind and concentrate completely!

It sounds simple, but for Naruto, who is used to being lazy and playful, it's harder than climbing to the sky!

Although he tried his best to concentrate on the lecture because he was afraid of the "baptism of lightning," he still couldn't help but drift off...

I want to steal a few glances at Sakura Haruno every now and then...

A moment later, I couldn't help but want to curse Sasuke a couple of times...

My stomach started growling again a little while later, and the image of Uncle Ichiraku's ramen, like heaven, kept swirling in my mind...

But every time he lost focus, the piercing warning sound would immediately ring out, forcing him to forcefully interrupt himself.

Feeling like sitting on pins and needles, like having thorns in one's back, like having a fishbone stuck in one's throat.

The time seemed to drag on endlessly, and I had no idea how much time had passed.

at last……

They waited until the moment when Iruka-sensei announced the end of get out of class.

Naruto felt like he had run three marathons; he deflated like a punctured balloon, quickly losing his dreams, and collapsed onto his desk with a thud.

Upon seeing this, Iruka-sensei instead revealed a slight smile.

"Naruto didn't cause any trouble at all during the whole class..."

"Moreover, his eyes were wide open like saucers, as if he was really listening to the lesson..."

"It seems my earnest advice did have an effect!"

He coughed and said, "Ten-minute break after class. The next class is Professor Shui Mu's chemistry class!"

"what--"

The classroom was immediately filled with wails.

But Naruto didn't even have the strength to howl anymore...

at this time.

[According to the schedule set by this system, the break time between classes is the perfect opportunity to overtake and outsmart everyone else!]

[Please begin practicing the Chakra Refining Technique immediately!]

[The current training time for Chakra Refining Technique must not be less than eight hours per day!]

Naruto: "...Are you kidding me?!"

Eight hours?!

"Do I still want to sleep?!"

[The system has detected that the host has not been training according to the schedule. The Lightning Release baptism is about to be activated...]

[Warning countdown, 5...4...3...]

"Ah ah ah ah ah!"

"I'll fix it, I'll fix it, okay?!"

Although Naruto was exhausted, he could only force himself to sit down when he thought of the terrifying power of the Lightning Release baptism. Then he began his training according to the basic chakra refining technique taught at the Ninja Academy.

The so-called Chakra Refining Technique, as the name suggests, is the process of extracting physical and mental energy from oneself, mixing and refining it into chakra that one can control.

To be precise, the so-called 130 trillion individual cells of a ninja produce a mixture of physical and mental energy, which is not chakra, but physical strength.

Physical strength exists in everyone's body, not just in ninjas.

At the same time, physical strength is the foundation for directly launching taijutsu. Of course, taijutsu can also be enhanced with chakra to increase its power.

To activate ninjutsu and genjutsu, one needs to convert physical strength into chakra.

The chakra refining techniques taught at ninja academies are essentially training that converts physical strength into chakra.

By continuously converting physical strength into chakra, one can increase the "upper limit" of their own chakra.

In other words, the so-called chakra amount.

As for chakra control and so on, that's a topic for later, and it's not a skill that Naruto can master right now.

Naruto's chakra reserves are undoubtedly enormous.

This is not only because the nine-tailed fox inside his body, through a special Bagua seal, is constantly leaking the fox's chakra and mixing it with his own chakra.

Furthermore, Naruto already possesses the bloodline power of the Uzumaki clan.

Their chakra reserves and vitality far exceed those of ordinary ninjas.

now……

It was during recess, and everyone else was laughing and joking. Sakura Haruno, Ino Yamanaka, and other girls surrounded Sasuke once again, while the boys were playing around in groups of three or five.

Only Naruto Uzumaki sat alone in the corner, quietly closing his eyes and beginning his training.

As he circulated the Chakra Refining Technique, his spiritual and physical energy mixed and slowly began to transform into chakra itself, which he could use to unleash ninjutsu.

To Naruto's surprise...

I was already exhausted from that class.

But now, practicing chakra refining techniques has not only not made me more tired, but has actually restored some of my strength...

Sure enough, human potential is infinite!

[Host has successfully activated the Chakra Refining Technique. Chakra level +1...]

As Naruto listened to the notification sounds in his mind, he suddenly felt that perhaps the system wasn't so bad after all...

Often, people don't work hard enough because they can't see the progress bar.

Once progress can be clearly visualized and even quantified, no matter how tedious the learning, practice, or work may be, it will bring powerful motivation and even pleasure.

Naruto is currently in this stage.

……

At this moment, Naruto's only two friends at the Ninja Academy, Choji Akimichi and Shikamaru Nara, were also staring at him in disbelief...

"Shikamaru, am I seeing things? Is Naruto practicing chakra refining techniques during break time? Ugh... ugh..."

Nara Shikamaru rubbed his sleepy eyes.

"Maybe I'm still sleepy..."

"I'm going to sleep a little longer..."

Choji Akimichi stared wide-eyed as he ate large bites of fries, his eyes bloodshot.

"Oh no, could Naruto be...?"
