Naruto: Immortal Spirit

"The seal of the root of tongue trouble..."

"Once you say something about the root, your body will be paralyzed and unable to move, and a curse seal of active attack will be attached."

"When the attack curse seal is activated, it will directly destroy the brain..."

"It seems that Danzo attaches great importance to you..."

As soon as Kato Oo opened his eyes, he found himself lying on an operating table.The head is fixed and the mouth is fully open.But he didn't feel anything, as if he had been given an anesthetic.

The deep snake eyes stared at his tongue with an almost cold-blooded silence.

"Kato-kun, the feeling of having your life in the hands of others shouldn't be so pleasant..."

Orochimaru slowly introduced a tube of medicine into his mouth. The paralysis in his body slowly eased, and he gradually regained consciousness, but his speech was still a little awkward.

"Gen, for...the village..., I am willing...to die..."

"There are about three ways to remove the curse seal. It seems that Kato-kun won't be interested."

Orochimaru glanced back at Kato Oo, silently observing the data displayed on the instrument, and when he saw that everything was normal, he was ready to leave.

"Lord Orochimaru, please call me 'Wei'. The root ninja has no past, no name, only a code name."

Kato Ou stood up and half-knelt on the ground. His perception had been opened to the greatest extent, and he did not notice other auras besides him and Orochimaru, but he could not tolerate being careless.

"It's really interesting... Kato-kun's love for life gave me a whole new feeling."

Orochimaru licked his lips, his erect pupils showed a strange interest, and he smiled softly, his eyes so deep that it seemed as if he could see through any disguise of Kato Oo.

"Read these scrolls as soon as possible..."

Orochimaru left many scrolls behind and disappeared into this inexplicable place.

Kato Ou slowly stood up and looked at the place.

Although the whole room was extremely bright, there was still some faint moisture. The flow of air in the vents above his head made Kato Oo understand that this was still a basement.

The walls and floors of the entire basement are made of solid rock bricks, which are so flat that they even have a hint of smoothness.

There are some special equipment placed everywhere, and various cables are connected to the hospital bed placed in the center.

It was the first time for Kato Ou to see such modern equipment and instruments, and he was slightly surprised.

"Is this Orochimaru's research laboratory? No wonder he has a special... scholarly temperament..."

Although he received very little information at the root, he also understood that the most popular people nowadays, besides Konoha White Fang, were the Sannin. Among them, Orochimaru was favored by many people and was a strong competitor to the Fourth Hokage.

It's just that he didn't expect that someone as humble as him, who was cautious and cautious at all costs, would actually have the opportunity to be favored by one of the three ninjas, Orochimaru.

"The art of spiritual transformation..."

Except for any other physical skills and ninjutsu that are the same as others.The only thing he has is his uniqueness in the art of spiritual transformation. No one in Konoha can use the art of spiritual transformation except him and Haruka Kato.

The Kato family's spiritual transformation technique, which has been passed down for thousands of years, has gradually improved their bodies through continuous practice.

Except for the blood of the Kato family, even if others obtain the secret technique, it is difficult to practice it successfully. Moreover, this secret technique involves the control of the soul, which is extremely dangerous. Some secret techniques are only passed down by word of mouth.

But even in the chaotic Warring States Period, the Kato family had never been so miserable. It was in danger and almost extinct. This was the first time...

"That's why I got this 'opportunity'..."

Guessing what Orochimaru wanted to do with the spiritual transformation technique, Kato Ou opened the scroll Orochimaru left for him.

"Illustration of Human Meridians", "Cell Theory", "Systematic Anatomy", "Colorful Atlas of Human Anatomy", hemostasis, healing...

"Also, palm magic..."

In addition to these basic medical books, the only thing that surprised Kato Oo was the palm sensibility. The famous palm sensibility is Princess Tsunade's most widely known and famous stunt.

Kato Ou has seen this kind of ninjutsu at first, but there are very few users. Although he is eager for this kind of general ninjutsu that can quickly treat trauma, he has no chance to learn it.

This is a life-saving skill.

"But before learning Palm Immortal Technique, you need to learn the Chakra Scalpel first..."

For Orochimaru leaving him so many books, he probably understood that Orochimaru was going to train him as an auxiliary tool person, and there would even be something involving the soul level in the future.

But that's still too far, now he just needs to unite closely with Orochimaru and be a perfect tool man.

"To learn the chakra scalpel, you must first learn the healing and hemostasis techniques..."

"Learning healing and hemostasis techniques requires understanding the structure and meridians of the human body..."

Kato Oo read the scrolls Orochimaru left for him bit by bit, and then he realized that none of the books Orochimaru left for him was useless.

Kato Oo had a rough look at the content he wanted to learn, and then he knew that there were too many things he needed to learn.

From the study of human meridians and cells to the completion of the art of palm immortality, I am afraid it will take at least a few years...

"Orochimaru shouldn't leave me so much time..."

Although today was the first time he saw Orochimaru, he could feel the indifference hidden under Orochimaru's snake eyes. He would definitely not leave too much time for himself...

"But becoming a medical ninja..."

"It's such an unimaginable path..."

Kato Oo sighed slightly, opened the scroll on the top, and began to study it silently, starting from the simplest ones, and slowly immersed himself in the scroll, forgetting the passage of time.

The afternoon passed slowly.

Fortunately, he had also learned relevant knowledge in his roots. These were not difficult things for him, but they were more systematic.

"Dong dong..."

A crisp knock on the door pulled Kato Oo out of the scroll. Before he could answer the door, the door of the research room opened. A carefree six or seven-year-old girl stood at the door with a bit of hostility in her eyes. You have to look at Kato Oo.

"Kato Oo?"

"There is no Kato Oo here, only the root ninja 'Mi'..."

Kato Ou glanced at the little girl at the door and responded casually.

He read the book contentedly and ignored her, but his attention was focused on the little girl at the door.

The habit he has developed at the root makes him look a bit colder than the root ninja. He is habitually indifferent, but he will not be careless.

The first lesson Kato Oo learned when he came into contact with the profession of ninja was to learn to be indifferent.In the past three years, I have felt the cruelty of the ninja world.

"Are you the genius Orochimaru-sensei mentioned?"

"It doesn't look like much..."

The little girl looked around him, looking unconvinced. After hearing her words, Kato Ou felt moved in his heart and looked at the little girl carefully.

Orochimaru's disciple?It seems...a little silly and sweet?

"My name is Hongdou, you want to call me Sister Hongdou, do you hear me?"

Anko was carrying a basket with water and a lunch box in it, and placed it in front of Kato Oo, as if waiting for Kato Oo's response.

"Okay, big sister."

Kato Ou didn't look at her anymore, his eyes were still on the book. He was memorizing the knowledge in the book. Since practicing the spiritual transformation, he clearly felt that his spiritual energy was growing rapidly, and his mind was getting better and better. The clearer you are, the better your memory is.

"Hey, you're so perfunctory!"

Anko hummed and placed the lunch on the table, then casually flipped through the books on the table.

"These seem to be books about medical ninjas...do you want to become a medical ninja?"

"If it's a medical ninja, it doesn't seem impossible..."

Kato Oo glanced at Anko, not knowing what she was thinking, but it seemed that the hostility she had just entered was gradually weakening.

"Okay, it's decided, I will allow you to join my and Orochimaru-sensei's team as a medical ninja."

"Okay, sorry to bother you."

Kato Ou chuckled, agreed casually, and ignored this somewhat innocent and lively child.

"Brother Kato, wait for me to send you a lunch box tomorrow..."

Anko seemed a little happy, and ran out without paying attention to Kato O's tone.

"Brother Kato..." Hearing this title, Kato Ou not only burst out laughing, but instead of thinking about anything else, he focused on the book.

It was quiet in the research room. Kato Ou stretched and opened his lunch box. According to his progress, he would be able to study these medical basics in about half a month, and then start trying to learn hemostasis and healing techniques. Although he Nothing is practiced.

"Why are they all meatballs?"
