Chapter 3: Joining Academy

In the early morning of the second day, the sun poured over Konoha, and the warm spring breeze blew everything.

The villagers of the village got up one after another to start a new day of work.

At the same time, in the house full of surveillance on the north side of the village, Aizen remained motionless, as if an old monk was in peace.

After a long time, he let out a turbit breath and finally opened his eyes. 

Throughout the whole night, Aizen continued to refine his spiritual power, and the gratifying thing is that after a night of refinement, Aizen already has a small amount of spiritual power in his body, which is enough to support him to use the first 15 Kidō.

What is important is that due to the mutation of the spiritual power seed, the spiritual power in Aizen and Chakra complement each other and are born together.

Chakra was created from a mix of spiritual and physical energy.

This gives him unlimited potential!

You know, the Chakra of each ninja is different.

Some ninjas are born with massive Chakras and are powerful. For example, Naruto, as a Uzumaki clan, he is born with massive amounts of Chakra. This was because the Uzumaki clan bloodline grants their shinobi enhanced lifeforce and vitality, and Naruto was not only the son of the princess of the Uzumaki clan but also the son of the Fourth Hokage which gave him a stinger body and higher physical energy.

However, there are also some ninjas who are not so lucky and lack Chakra by nature, and will collapse after only a few ninjutsu.

This kind of ninja often cannot be the top powerhouse, they are limited to a life of mediocrity because the lack of Chakra is a flaw.

Now, this tricky situation is perfectly solved by Aizen.

Due to the change of the spiritual power seed, Aizen can continuously produce and increase his Chakra as long as the spiritual power is extracted.

In this way, Aizen's Chakra can not only accumulate over time, but it can also be refined to become several times stronger and more dense than other ninjas.

Because his Chakra contains spiritual power!

"According to the old man's statement, today I will attend to the Ninja School and be an interim student."

"Heh, I never really thought that the kind of life that I had lived in the Mao Academy of Spirituality for hundreds of years will come again."

Aizen doesn't object to going to ninja school in his heart.

On the contrary, he is very interested in the practice of ninjutsu.

As a strong man who pursues the limit, Aizen is eager to control this new power.

In the corpse soul world, Aizen was already at the top of Shinigami. It wasn't until later that he defected to the corpse and soul world, ruled the Soul Society, and finally merged with the cube, that Aizen truly surpassed Shinigami.

Unfortunately, Aizen was sealed by Kisuke Urahara and Ichigo, and the power of cube also abandoned him. 

Aizen eventually became a prisoner. However, that kind of supreme power made him linger for more.

"Ninja Academy, known as the cradle of countless ninjas. If all young ninjas were hit by Kyōka Suigetsu, what would it be like?" Aizen smiled codly, and his mad thoughts came out of him.

He wants all the students of the Ninja School to watch the Shikai of Kyōka Suigetsu.

In this way, in the future, almost all ninjas will be played and applauded by him.

Once Kyōka Suigetsu's illusion is hit, the end is self-evident.

"Kyōka Suigetsu, show up." Aizen walked to a blind corner of the room, where there was no surveillance. 

Throughout the night, in addition to refining spiritual power, Aizen also secretly sensed the house's monitor.

A ball of light gushes from the palms of his hands, constantly emitting a white luster.

After the light appeared, it quickly spread to both sides, gradually concentrating as a long sword.

The green hilt, the sharp blade, the Zanpakutō that scared the soul world back then appeared again.

However, this brand new Zanpakutō is different from Aizen's impression. 

The new Kyōka Suigetsu is only less than half a meter long, which is about the same width as Aizen's body.

"It turns out that this is the case. As my age regresses, my strength declines. Zanpakutō's strength is also lost."

Aizen gently stroked the blade, a trace of nostalgia flashed in his eyes. 

After never being recognized by the cube, Kyōka Suigetsu's sword automatically disappeared, and after many years, it finally reappeared again.

"Konoha's Ninja School, what kind of surprises will you bring to me."

Aizen expects that because of the passing of power, he has adapted to the role of the weak, and his mentality is completely correct.

Ninja School

In a spacious classroom, dozens of students are attentively attending class.

In the lecture hall, a young teacher was teaching the students some basic ninja knowledge.

The teacher was plain, with even dark skin, and was not too conspicuous. 

However, the scar on the bridge of his nose is particularly eye-catching, like a horoscope.

This young teacher is the enlightened teacher for all students, Iruka.

At this time, Iruka is holding a textbook tirelessly giving lectures. 

From time to time, his gaze was aimed at the bottom of the lecture hall, his brows were slightly frowned, as a figure attracted his gaze again.

"Naruto, concentrate on listening to the class. If you don't pass the exam, you can't graduate from the ninja school."

Iruka shook his head helplessly, feeling helpless for Naruto.

Naruto is not only fun by nature, but also the tail of the crane in the class. 

If it weren't for Iruka's constant supervision, I'm afraid Naruto is still far short of the qualifications to graduate from the Ninja School.

Naruto showed a fearless smile and said, "Don't worry, Mr. Iruka, I am going to be a man from Hokage."

"Come on, he's not just a clown, but also wants to be Hokage."

Behind Naruto, a disdainful sneer sounded.

Naruto turned his head angrily, and when he saw that cold face, he instantly withered.

That is was the of the Uchiha, Sasuke Uchiha, and the outstanding student in this class.

In addition to a few of them, there are many immature faces.

Haruno Sakura, Nara Shikamaru, Akimichi Chōji, Yamanaka Ino, Aburame Shino, Inuzukaga, Hyūga Hinata and other Konoha twelve. 

Before graduating from the ninja school, they all studied basic ninjutsu in the same class.

Just as the atmosphere in the entire classroom became active, the teacher's door was pushed open. 

Suddenly, everyone's eyes turned to the door, and they found a teenager with a gentle smile on his face appeared.

"My name is Aizen Sōsuke, I am a new transfer student, please advise!"

There was a gentle smile on the handsome face of the boy, like an innocent boy.

"Dear students, he is our new transfer student, Aizen Sōsuke."

"Although the Genin exam will be held soon, this teacher hopes that you can get along well with this new student during this time." Iruka smiled at Aizen and nodded, motioning him to enter the classroom.

"It turned out to be a new classmate. It was great. Finally, a new face appeared." Naruto laughed heartily, and his eyes were tightly attracted by Aizen.

He found that Aizen always had a gentle smile on his face, which gave people an optimistic and sunny impression.

"Oh, it's really troublesome. I have to adapt to new classmates again." Nara Shikamaru shrugged helplessly, but simply scanned Aizen's eyes without paying too much attention.

"It's great, there is a new colleague to join, we must get him to have a barbecue!" Akimichi Chōji's thoughts were full of delicious grilled meat.

For him, it doesn't matter who the new classmate is. The key is to have grilled meat to eat.

Sasuke just looked at Aizen coldly and lost interest.

As a genius of the Uchiha clan, he is confident that he can overcome others and become the strongest leader.

In addition to these individuals with distinctive personalities, more than 30 other students welcomed Aizen. 

It's just that there is an awkward smile on one of the immature faces.

Hyūga Hinata looked at Aizen timidly and whispered to herself, "This idiot, it will be the Genin exam soon. He joins our class now, I am afraid that he will not have the qualifications to graduate."

As early as by the river, Hinata used Byakugan to observe Aizen, and she found that there was no Chakra fluctuation on the opponent, just an ordinary teenager.

But more importantly, their students will take the Genin placement test soon, if Aizen joins at this time, it will likely only result to replacing the position of Naruto.

"Well, now that the introduction has been completed, as usual, new students will have to take a Chakra test."

Iruka took out a round crystal ball from under the podium, and a dim fluorescent covering its surface, seemingly flowing with a mysterious power.

Aizen asked suspiciously, "Chakra test?"

Iruka explained with a smile, "Yes, this is the first step. Each student will take a Chakra test, which will help us understand your approximate strengths, and I allow me to specify a special course in the future."

As a ninja, Chakra is the most basic power, and the strength of Chakra often determines the power of ninjutsu.

Of course, in addition to Chakra, the strength of a ninja also depends on talent, comprehension, blood inheritance, ninjutsu practice, and so on.

However, Chakra is the most important link.

"This crystal ball is a tool specially developed by our Konoha Shinobi Village to test the Chakra of the Ninja Academy's students."

"You only need to inject the Chakra in your body into this crystal ball, and it will emit different colors."

Iruka shook the crystal ball in his hand, and suddenly emitted a soft dark blue light, which represented that Iruka possessed Chūnin's strength.

"There are five colors of the crystal ball, divided into students, Genin, Chūnin, Jōnin, and Kage level. Their corresponding colors are white, green, blue, purple, and red."

"There are also strong and weak differences in the same level. The darker the color, the greater the concentration of Chakra. However, above these five colors, there is also a legendary gold. This power has already surpassed the level of a Kage, and only the power that a legendary individual can be competent."

Speaking of the power of the legendary Six Paths, Iruka's face is full of admiration.

Every ninja has a dream of being strong, Iruka is no exception, but he is limited because of his talent, and he is currently just an ordinary Chūnin.

"Five colors? I wonder if my spiritual power can awaken the sixth golden color." Aizen's friendly smile seems to be listening to Iruka's words attentively.

In fact, his thoughts have stayed on the power of the Six Paths.

Through the information provided by the system, Aizen has learned that Sage of Six Paths was the strongest person who had ever existed, and the Ten Tails Jinchūriki.

The power of the Six Paths in him also represents the top existence in the world.

Iruka smiled and handed the crystal ball to Aizen and said, "Then, Aizen, please inject Chakra into the crystal ball, let us see what kind of light you can awaken."

Aizen took the crystal ball, looked carefully, and injected Chakra into it. 

At this time, he has become the focus of the entire classroom, his every move has attracted attention and everyone wanted to see what color Aizen can shine.

A buzzing sound was heard, and with the injection of Chakra, the crystal ball was revived, its interior changed, and a new light appeared.

Everyone held their breath and watched the crystal ball attentively. 

It's just that when everyone looked at the crystal ball, they all showed a disappointed expression.

There is no green as expected, nor full-bodied white, just plain white.

In addition, the white color on the crystal ball is very dim, which shows that the Chakra in Aizen's body is less pitiful, and only better than the entry-level students.

"Hahaha, it turned out to be the lowest, a light white. Naruto, it looks like your clown's position is about to be replaced."

The sound of laughter from a corner of the classroom broke the silent atmosphere, and suddenly everyone burst into laughter.

The result of the crystal ball was beyond their expectation. They did not expect was that Aizen's strength was so weak, it could be said that it was only slightly better than an ordinary civilian.

"Cut, it's really wishful thinking to join us with this strength. In my opinion, the first repeater in the history of our Ninja Academy will appear.

After seeing the faint white light, everyone's attitude changed. The previous warm, greeting and welcoming atmosphere had changed, and replaced with looks of cold, ridicule, and dispain. 

In this world where there are many strong people, having no strength can only be destined to be ridiculed.

"Hey, I knew there would be such a result a long time ago, and I hoped he won't be sad." Hinata sighed in frustration, praying inwardly that Aizen would be confident.
