Chapter 4

In the forest behind the Ninja School.

Shurikens and kunai flew from all directions toward Shiroishi.

Shiroishi faced this terrifying scene with a calm expression, gripping a kunai in one hand. His body twisted, and the kunai in his hands swiftly cut through the air.

The sound of clashing metal echoed continuously, and sparks flew as the incoming kunai and shurikens were all deflected by Shiroishi, scattering at his feet.

Shiroishi exhaled slightly, looking at the densely scattered kunai and shurikens around him, his expression still calm, as if achieving this level was a matter of course.

But to deflect such a large number of kunai and shurikens without a scratch, even a fully trained genin from the Ninja School would find it difficult to do so.

Shiroishi could achieve this not only because of his hard work but also because of his outstanding motor nerves and superior dynamic vision.

This was Shiroishi's inherent talent.

Moreover, Shiroishi had used some scientific training methods from his previous life to further enhance his motor nerves and dynamic vision.

Therefore, after just two months of systematic training, achieving this level was not surprising to Shiroishi at all.

In his previous life, as a senior doctor, he had an exceptional understanding of human anatomy and knew the importance of motor nerves and dynamic vision for a ninja.

Strong dynamic vision allowed him to better capture the trajectory of an enemy's movements and attacks.

Outstanding motor nerves enabled him to react quickly in battle, giving him an advantage.

Thus, even with already excellent motor nerves and dynamic vision, Shiroishi still developed a training regimen tailored to his physical condition to further improve these abilities, striving for perfection.

Shiroishi was well aware that his greatest advantage was not his actual motor nerves and dynamic vision, but the vast knowledge from another world stored in his mind.

This was the foundation of his existence.

The power of knowledge is boundless.

Knowledge can cure the ignorance of the mind, strengthen one's resolve, and prevent being dominated by ignorance.

Knowledge can also cure physical weakness, teaching one how to become stronger more effectively.

After collecting all the kunai and shurikens from the ground, although these ninja tools were already damaged, Shiroishi's funds were not particularly abundant. Even a piece of iron had to be used to its fullest potential, and nothing could be wasted.

After all, he was still growing, and he could not neglect his diet, ensuring his body received sufficient nutrition.

After putting away the ninja tools, Shiroishi did not leave. Instead, he wrapped his fists and legs with white bandages and practiced taijutsu against a sturdy wooden post.

It was already night, and the forest behind the Ninja School was quiet. Only Shiroishi's slight panting and the sound of his body colliding with the wooden post could be heard as time slowly passed...

The next morning.

"Good morning, Ayame."

After two months of interaction, Shiroishi and his desk partner, Hinata Ayame, had become very familiar, and he addressed her casually.

"Good morning, Shiroishi-kun."

Compared to Shiroishi's casualness, Ayame, as a member of the Hyuga clan, had to maintain the various formalities of a large family.

Through these days of interaction, Shiroishi also learned that Ayame came from the Hyuga clan's branch family in Konoha, and her white eyes were a traditional characteristic of the Hyuga clan.

Ninjas from this clan used a bloodline limit called the Byakugan, which, when combined with the clan's Gentle Fist technique, was renowned in the ninja world.

"Good morning to you too, Ruri-san."

Sitting down at his desk, Shiroishi smiled and greeted the girl on the other side.

Uchiha Ruri only gave Shiroishi a cold glance and did not respond, as if she was admiring herself, watching the playground outside the window as usual.

"By the way, have you heard, Shiroishi-kun?"

"What?"

Ayame spoke, and Shiroishi turned his head, looking at her with confusion.

"Apparently, there will be a practical class today."

"Practical class?"

"Yes, it's a type of practical class, but not the kind where you throw shurikens. It's a practical class where students pair up and compete."

Ayame's voice was gentle.

"I see, that sounds a bit challenging for me, but it shouldn't be a problem for you, Ayame."

Among the three students in Shiroishi's row, Shiroishi's grades were the most ordinary and unremarkable. He excelled only in theoretical exams, while his performance in shuriken throwing and physical tests was average.

He was neither a poor student nor an excellent one.

Of course, this was a result of Shiroishi's deliberate effort.

In contrast, Uchiha Ruri, who was cold and spoke no more than three words a day, consistently held the top position in the class, excelling in both theoretical and practical classes.

Ayame was slightly behind but still ranked in the top five of the class.

Like Ayame, Ruri also came from a prestigious clan in Konoha—the Uchiha clan.

She possessed a bloodline limit called the Sharingan.

The probability of activating the Sharingan was lower than that of the Hyuga clan's Byakugan, but its power was greater.

Moreover, Uchiha clan ninjas were skilled in shurikenjutsu and fire release techniques.

Shiroishi gradually learned these facts.

Shiroishi couldn't help but marvel at the advantages of being born into a prestigious clan, as the starting line was far beyond what a commoner could compare.

"We'll do our best together, Shiroishi-kun."

Ayame encouraged Shiroishi.

"Sure, if I end up paired with you, please remember to go easy on me."

Shiroishi did not want to reveal his true strength, so he deliberately scored average in all previous tests.

An average position was just right for Shiroishi.

Therefore, if he were to face Ayame as an opponent, Shiroishi had already decided that the best course of action would be to endure for a while and then lose the battle.

He was just an ordinary person and could not achieve outstanding results.

Of course, if he were to use his current full strength to fight Ayame, he might still lose.

After all, she was a member of the prestigious Hyuga clan and likely received additional training from her elders.

There was a significant gap between commoners and clan system ninjas.

He only needed to maintain the normal level of a commoner.

That said, the outcome was often unexpected.

During the first practical class—

As Ayame had mentioned, the homeroom teacher, Fujimura Daigoro, organized the first practical test for the first-year A class, with students pairing up to compete. He himself stood outside the circle, notebook in hand, ready to take notes.

However, Shiroishi's partner was not Ayame but Ruri, another desk partner and a genius girl from the prestigious Uchiha clan in Konoha, on par with the Hyuga clan.

For the practical class, the shurikens used by the students were made of wood, with the sharp parts removed and the edges smoothed, so even if they hit a person, they would only cause pain and not pose a life-threatening risk.

"This is so boring, using these toys to compete."

The Uchiha girl, standing next to Shiroishi, scanned the two boys in the middle of the field with a haughty gaze, her face showing clear disdain.

"Ruri-san, that's not a good thing to say, we are still first-year students."

Shiroishi hesitated for a moment and quietly reminded Ruri not to provoke the others.

For most students, using real shurikens and kunai from the start could easily lead to bloody incidents.

"Compared to others, you should worry more about yourself. When we fight, I won't hold back."

Shiroishi gave an awkward smile and said no more.

Time passed quickly, and it was Shiroishi's turn to step into the ring.
