Konoha: Naruto, trained by Aizen

"Slashing techniques are divided into swordsmanship and slashing skills. Swordsmanship is the fighting technique of the Zanpakuto, which cultivates powerful spiritual strength by honing one's mind and will."

"Slash techniques, similar to Iaido, are designed to kill with a single, decisive blow. Slash techniques can be honorable or despicable, but they all have one purpose: to defeat the opponent. In other words, slash techniques are killing techniques that exist solely for the purpose of combat."

Aizen's voice echoed in Naruto's mind.

In the world of Bleach, Captain-Commander Yamamoto tried to teach Kenpachi Zaraki swordsmanship when Kenpachi joined the team. He hoped that Kenpachi would replace his original, primitive and bloody fighting methods with standardized combat techniques and the spirit of swordsmanship, and that the latter would gain some spiritual insight.

Unfortunately, the latter had absolutely no interest in learning it.

Based on the history of Team 13, Yhwach once described the former Team 13 as "Sword Demons" because the former members of Team 13 used slashing techniques rather than swordsmanship.

Later, when Captain-Commander Yamamoto and the first Kenpachi Hana both switched to swordsmanship, the entire Squad 13's outlook on life and the world changed.

Aizen knew the history of the 13th Division and scoffed at kendo.

In his view, a Zanpakuto is a weapon for killing, and the so-called spirit of swordsmanship is simply a burden in battle.

Team 13 is too weak now and poses no threat to him at all.

"You make the decision yourself: whether to learn swordsmanship or swordsmanship."

Aizen left the choice to Naruto himself.

"I choose the cutting technique." As expected, Naruto chose the cutting technique without hesitation.

"Slaying technique? I'm really looking forward to your first kill. The first time you face something is always filled with fear and dread, like a flower blooming on a cliff. We all stop at the edge of the cliff, instead of taking a fearless step towards the sky like the flower. Once you successfully take that step, you will no longer be the Naruto Uzumaki you once were." Aizen's lips curled into a smile, his eyes filled with amusement.

.......

one year later.

Konoha 53th year.

Today is also the day Rock Lee enters the Ninja Academy.

The day before starting school, Rock Lee chatted with Naruto for an entire afternoon.

The gist of it is that he is very nervous and hopes that he has good ninja talent. He hopes to become a ninja who excels in taijutsu but is also good at ninjutsu.

He had high expectations for himself.

Naruto did not send Rock Lee to the Ninja Academy because he did not want Rock Lee to suffer cold treatment because of him.

He offered his heartfelt blessings to Rock Lee and quickly moved among the trees.

By concentrating spiritual pressure at the soles of the feet, one can accelerate forward movement; this is a fundamental skill that needs to be mastered before learning Shunpo.

During this year, Naruto also gained a general understanding of the Bleach world where Aizen lived.

In the worldview of Bleach, there are two concepts: spiritual pressure and spiritual power.

The higher a person's spiritual pressure, the more spiritual power they can utilize.

Spiritual power is the main substance that constitutes the soul.

A qualified Shinigami can use the spiritual energy within their body to create spiritual pressure through leakage, which can intimidate enemies. They can also use spiritual energy to solidify various weapons or barriers.

Naruto has good talent; he has mastered the basic use of spiritual pressure within this year.

This greatly alarmed Aizen.

For novice Shinigami, the most difficult thing is controlling their spiritual pressure.

But Naruto did all of this perfectly.

Naruto was naturally proud of this and was full of anticipation for his future ninja career.

"My talent as a Grim Reaper is so outstanding, I'm sure my talent as a ninja won't be bad either. I want to become a ninja who is proficient in ninjutsu and a Grim Reaper who is proficient in demonic arts."

Naruto returned home. He didn't train today because he was about to begin something extremely important in his life: chakra extraction.

Five-year-old Naruto was already able to start training his chakra, and the Third Hokage promised to send Naruto related books on the first day of school.

According to the rules of the Konoha Ninja Academy, children who are six years old or older and have ninja talent can go to the Ninja Academy to study.

Naruto is still a year away from turning six, but he is already preparing to learn related knowledge in advance.

Members of all the major clans in Konoha would begin chakra training before entering the academy. This was partly because the clans had the resources, and partly because they hoped their members would excel after entering the academy and live up to the clan's reputation.

The Konoha leadership had a heated debate over Naruto's chakra training.

The main characters are naturally the Third Hokage and Danzo, two best friends who love and hate each other.

In Danzo's words, "By handing Naruto over to Root, I can forge him into the most perfect weapon of Konoha in history, and he will become a force to be reckoned with in other ninja villages."

The Third Hokage believed that Naruto could perfectly inherit the Will of Fire, and that sending him to the Ninja Academy to form bonds with other students was the right solution.

After all, there is the successful example of Kushina Uzumaki. Kushina Uzumaki found her true love while studying, became one of Konoha's top fighters, and even gave birth to Naruto Uzumaki.

This proves that the three-generation theory is feasible.

Finally, after Danzo argued his case, the Third Hokage once again brought up the Hokage theory, successfully 'debating' Danzo into silence, who then stormed off in anger.

"Since you had already made your decision, why did you ask for my opinion?" Danzo's dissatisfaction with the Third Hokage deepened, and his desire for the Hokage position also increased.

Regardless, Naruto is the biggest winner in this debate.

He had the opportunity to learn chakra ahead of time.

Naruto sat on the bed in the room, holding Kyoka Suigetsu in his arms, waiting excitedly like a child about to receive his favorite toy.

If I learn chakra, will I be able to use ninjutsu?

How is chakra used?

What is the difference between chakra and spiritual pressure?

His mind was filled with a desire to explore the unknown.

"Knock knock." A knock suddenly sounded at the door. Naruto immediately ran excitedly to the door, opened it, and found no one outside. However, there were two books on the cold stone steps.

"Thank you." Naruto nodded slightly to the trees, then carried the books back into the house.

The gate closed tightly again, and the leaves swayed slightly.

Chapter Twelve: Training in Basic Chakra

A Preliminary Method for Chakra Refinement

Mastering the Three-Body Technique

Back in his room, Naruto eagerly opened the book.

At the same time, Aizen was also reading the book.

"Chakra is the energy source of a ninja. The more chakra a ninja has, the stronger he/she tends to be."

"The founder of the Will of Fire, the First Hokage, possessed chakra that was unimaginable to ordinary people, and was once known as the God of Shinobi."

"Then the Third Hokage appeared out of nowhere. Although his total chakra was not as much as the First Hokage's, the Third Hokage was revered as the Professor of Ninjutsu by the ninja world for his superb ninjutsu. His strength was unknown, and it may even have surpassed that of the First Hokage."

Aizen read the book with Naruto, his brows furrowing more and more as he read.

Is the third generation very strong?

He recalled the Third Hokage's aged figure and the chakra he felt.

The Third Hokage may have been a seasoned ninja, but to say he was the best in the ninja world would be an exaggeration.

If everything is true, and the Third Hokage is indeed one of the strongest ninjas in the entire ninja world, then the strength of the ninja world is far too weak.

I have a feeling that this book contains my own agenda.

Aizen was somewhat disappointed.

His biggest worry was discovering that the ninja world was a lower-dimensional world compared to the world of death.

This would mean a sharp decrease in the value of the ninja world.

Aizen patiently continued watching.

"An excellent ninja needs to be proficient in taijutsu, ninjutsu, and genjutsu!"

"Ninjutsu is the technique of extracting and using chakra from the body, or of directly utilizing the ninja's physical body."

"Taijutsu, as the name suggests, is the use of one's own body to attack the enemy's physical body. Taijutsu generally does not require chakra, so physical training is closely related to the strength of taijutsu."

"At the same time, physical training is quite tedious and requires time and perseverance."

"Physical techniques are also divided into two types. One type causes injuries such as fractures and tears to the opponent, which is called steel fist; the other type uses chakra to destroy internal organs and meridians, which is called gentle fist."

"The last type of illusion. It uses chakra to pull the opponent into a constructed illusion, causing both physical and psychological damage."

"Of the three attack methods, illusion requires the most control over chakra."

"How to refine chakra..."

Naruto was so engrossed in reading that he soon began his first attempt at refining the ingredients, following the methods described in the book.

“The way chakra is used is somewhat similar to spiritual pressure, so it should be easy to learn. Given Naruto’s talent in spiritual pressure, refining chakra should be quick.” Aizen nodded to himself.

He did not follow the instructions in the book to refine chakra.

No one knows whether spiritual pressure and chakra can coexist. Only after ensuring that everything is foolproof and that chakra does indeed help with strength will Aizen begin to train in chakra.

......

Naruto sat quietly like that all night.

Chakra and spiritual pressure are similar in that they both exist in the body's energy channels. By calming the mind and concentrating, one can capture and gather them.

However, compared to chakra, spiritual pressure seems to be more cunning and unpredictable.

Having successfully awakened spiritual pressure, extracting mere chakra doesn't seem so difficult anymore.

After a night, Naruto opened his eyes and slowly exhaled a breath of stale air. His eyes were bright and clear, showing no signs of fatigue from staying up all night.

His lips curled up in a smile, full of joy.

"I succeeded." Feeling the chakra flowing through his body, he couldn't help but clench his fist.

"We're one step closer to our goal."

He took a deep breath, his eyes filled with joy and anticipation.

The spiritual pressure did not conflict with the chakra. They flowed through Naruto's body like two friends who did not interfere with each other, forming two powerful forces.
