Naruto: Immortal Spirit

The days in the laboratory did not last as long as Kato Oo imagined. Less than a week later, he met Orochimaru for the second time.

Orochimaru with Anko seemed a little softer than usual, and Kato Oo's eyes couldn't help but fall on Anko.

"Kato-chan, would you like some meatballs today?"

Anko held three bunches of glutinous rice balls in her hand. After thinking about it, she took out one bunch and handed it to him, and then handed another bunch to Orochimaru.

"Thank you."

Kato Oo took it without any politeness and held it in his hand because he saw Orochimaru also took it.

"The relationship between Kato-kun and Anko seems to be very good..."

Before Kato Oo spoke, Anko was already grinning.

"Of course, little Kato is the most obedient I have ever seen. He is much better than those guys in school who only know how to cry."

After eating the meatballs cleanly, Anko seemed to be a little unfinished. Orochimaru handed the temporarily stored meatballs back to Anko.

"Lord Orochimaru, my subordinate Wei, has finished studying cytology and systematic anatomy. It is expected that he can start learning hemostasis and healing techniques in a week..."

Kato Oo stood aside respectfully and handed the meatball in his hand to Anko again.

"Kato-kun is really awesome."

Orochimaru turned his head, smiled and touched Anko's head.

"Anko, go practice the ninjutsu I taught you. Kato-kun is almost surpassing you..."

"Huh?" Anko stared at Kato Oo, then seemed to feel embarrassed when she thought of the meatballs in her hands, so she snorted and ran out.

Anko left, and Orochimaru put away his only softness, looking at Kato Ou with a faint look.

"Kato-kun, I have a gift, maybe you will like it."

The lights in the laboratory were very bright, and Kato Oo watched Orochimaru take out a scroll from his sleeve.

"It's very fresh. It should be enough for you, Kato-kun."

"untie!"

Orochimaru gave a soft drink, and two fresh corpses appeared on the hospital bed in the laboratory, one male and one female.

The body was intact, with only a wound on the neck, and blood was still flowing slowly. Kato Ou's visual inspection showed that their death time should not exceed two hours.

"Lord Orochimaru..." Kato Oo was stunned for a moment, looking at the two corpses lying on the test table, feeling a little dazed for a moment.

Although this wasn't the first time he saw a corpse, and it wasn't like he had killed others in battles.

But he understood what Orochimaru meant - these two people were the subjects of his anatomy.

The horror of dissecting a person far exceeded that of a kunai that took action in an instant. Although he had already mentally prepared himself before, he was still a little at a loss when facing such a scene for the first time.

"Kato-kun can use it at will. In three days, I will replace Kato-kun with a new experimental body."

There seemed to be a faint light in Orochimaru's eyes, and he just stared at Kato Ou with a slight smile. It was a gaze as cruel and cold as an animal.

Kato Ou felt that the temperature Orochimaru looked at him would not be much better than the two people lying on the experimental table.

"Yes! Lord Orochimaru!"

When you are in a difficult situation, you must have the awareness of being in a difficult situation. No matter what you do, he has no capital to refuse.

Orochimaru's eyes narrowed slightly, and he seemed to stare at Kato Ou with some scrutiny and surprise. He smiled softly, and seemed to take out a scroll from his sleeve on a whim.

"Kato-kun is very different from ordinary children..."

Kato Ou lowered his head and did not look into Orochimaru's eyes. He didn't quite understand what Orochimaru meant.

"The Art of Darkness, learning difficulty level A, was developed and perfected by the Second Hokage. It creates a dark environment, causes visual hallucinations, and takes away all light. In the dark world where pitch black satin descends, the only way to do this is to cast a spell Those who can’t be affected.”

A scroll was handed in front of Kato Oo, and Orochimaru's slightly seductive tone told Kato Oo that this was his 'wage'.

"Kato-kun, although it is an A-level difficulty, I think it shouldn't be a problem for Kato-kun."

The firm and convincing words made Kato Oo feel waves in his heart. He suddenly raised his head and looked at Orochimaru as if in disbelief.

The intensity of his spiritual energy has grown day by day in the past three years of learning the art of spiritualization. He has also encountered several items that contain the spiritual will of others, which made his spiritual ability advance by leaps and bounds as if it were evolving.

But I thought that I had hidden it very well, and no one discovered it even at the root, but I didn't expect to be exposed by Orochimaru, who had only met twice.

Kato Ou didn't know what the relationship between Orochimaru and Danzo was, but it didn't seem to be what he imagined. It seemed that Orochimaru was not completely controlled by Danzo. Although at the root, he had his own power.

"Lord Orochimaru, Kato Oo will complete the dissection task as soon as possible!"

"Haha, hahaha..."

Orochimaru's laughter seemed to contain some other meanings, but Kato Oo didn't want to understand or pay attention to it. He just remained silent, took the scroll, and held it in his hand.

"One of the three ways to unlock the curse seal is that when the person who cast the curse seal dies, the curse seal of the person being casted will be automatically released."

Orochimaru's last words took away all the warmth in the laboratory. Kato Ou silently looked at the tight laboratory door, his hands clenched until they turned white.

……

The dissection work was not very smooth. He just turned the pictures in the book into real objects.

However, when he took out the experimental subject's completely cold heart from his chest and held it in his hand, his eyes were fixed on the experimental subject's face, motionless.

This is a middle-aged man, about 30 years old, who is in the golden period of his life.

He didn't know what this man did in life. Maybe he was also a ninja. Maybe he thought about the meaning of life like himself. Maybe he wanted to live like he did, but he failed, so he became own experimental subjects.

But at this moment, a huge biting coldness descended on him, as if a huge glacier began to wrap around him inch by inch. His whole body was imprisoned and motionless, and his heart began to beat violently, like a hand. The cold heart in his chest made the heart in his chest feel the same sadness.

"Human life is imprisoned in the body, it is so fragile..."

He slowly put down the thing in his hand that had turned into an unknown mass of blood foam. The blood stains remaining in his hand were still falling down his fingertips.

"Even if it's just a gentle exertion..."

His bloody fingers kept interlacing, and his body became motionless. A shadow emerged from his body and floated over the laboratory.

"The art of spiritualization!"

His consciousness seemed to be completely empty, allowing his soul to wander.

The soulless body lying on the hospital bed on the side seemed to be the same as the experimental subject that had lost its life.
