Naruto: Immortal Spirit

Kato Ou himself never thought that he had such great potential, but in just over a year, under the double haze of Orochimaru and the curse seal, he seemed to have changed into a different person and grew up rapidly.

"The results of cell chakra analysis show that after the experimental subject was injected with culture medium, the energy density of single cells increased by 30%..."

The high-precision chakra analyzer is now completely controlled by Kato Oo, and Orochimaru has also thrown all the small experiments to Kato Oo.

"How's your mental stability?"

Orochimaru does not often spend time in the laboratory. There are still a large number of S-level tasks in the village that need him to complete. He will spend about a few days every month to personally guide Kato Oo and promote the progress of experiments.

"The mental stability of the experimental subjects is poor, and they have a certain degree of emotional control, accompanied by some memory loss..."

Kato Oo and Orochimaru came to the cell where the experimental subjects were held. Each experimental subject was held separately. These emotionally unstable experimental subjects often made some bizarre behaviors.

The dark basement seemed even more gloomy with the flickering candlelight on both sides, and some tiny sounds could be heard from time to time.

"Boom...boom..."

Hearing the footsteps of people, the two experimental subjects immediately threw themselves on the cage and roared. The thumping sound kept coming. Kato Oo's eyes were focused on the deepest cell. There was an experimental subject who banged his head against the wall every day. .

Orochimaru looked at these experimental subjects one by one with great interest, but his eyes narrowed slightly.

"Kato-kun, the fusion liquid still needs to be improved. This kind of thing is too rough..."

"Yes, Lord Orochimaru!"

Back in the research room, Kato Ou seemed to be hesitant to speak. He found an experimental report from the towering stack of books on the side and handed it to Orochimaru.

"Lord Orochimaru, there seems to be something wrong with the experiment.

During cell analysis, a special substance is mixed in the fusion solution, which will greatly affect the stability of the fusion solution. "

"During a deeper analysis, it was discovered that one of the main culture base fluids used to synthesize the fusion fluid seems to be the tissue fluid of an unknown organism..."

"And this substance all comes from this tissue fluid..."

Kato Ou looked up at Orochimaru. Over the past year, he was somewhat familiar with Orochimaru.

Grim Frankenstein.

Compared with other matters, Orochimaru was not so cold-hearted about experimental problems. As long as it could promote the progress of the experiment, he would tell him everything.

This culture base fluid used to synthesize the so-called fusion fluid, after Kato Oo's analysis, it can be determined with a high probability that it was extracted from a certain person's cell tissue fluid, but Orochimaru never seemed to mention this.

"Kato-kun is so perceptive..."

Orochimaru's snake eyes always made Kato Oo feel like he was being stared at by some vicious beast, but he was used to it.

"You are right, this kind of thing is extracted from a person's cells, and these fusion fluids are just preparations for transplanting this kind of cells."

Orochimaru's faint voice allowed Kato Oo to verify his guess, but it also allowed him to get to know the ninja world again.

"Just the special substances mixed in the extracted tissue fluid have such a strong exclusivity that they not only affect the body, but can even affect the mind..."

"If it were a complete cell..."

Based on Kato Oo's current knowledge, he could not figure out how to transplant this kind of cells into another person.

And what kind of divine figure is the owner of this cell?

"Kato-kun, maybe this is the time to show your value..."

Orochimaru pursed his lips and looked at Kato Oo with some scrutiny.

"Lord Orochimaru, please give me your orders!"

From the first time he came into contact with Orochimaru more than a year ago, he already knew that this day would happen.

"Kato-kun, it seems that you already knew that such a day would come. You are really smart..."

Orochimaru chuckled lightly and took out a glass tube from his cuff. There was a piece of flesh and blood the size of a fingernail floating in the light green nutrient solution. It was constantly squirming as if it wanted to break out of the test tube.

"Kato-kun, have you seen the scenery on Hokage Mountain?"

"I've been there several times before, before I joined the Roots... Looking at the entire Konoha from Hokage Mountain, I have a panoramic view of Konoha's scenery..."

Kato Ou didn't know what he thought of, and he felt a little inexplicable, and he woke up after a moment.

"Kato-kun seems to be very touched..."

"I just thought about my uncle. His legs and feet have never been very good..."

Orochimaru's eyes had an inexplicable look. He glanced at Kato Ou silently, and then slowly spoke.

"Three years ago, Kato Yuan, the last patriarch of the Kato family, died of illness at home..."

Kato Oo was stunned. He looked directly at Orochimaru. This was the first time he looked directly into Orochimaru's eyes. He knew that Orochimaru would not lie to him, at least in this matter. There was no need for him to lie to him.

"I see……"

Kato Ou lowered his eyebrows and couldn't see his face clearly.

"The death of a loved one always makes us feel sadness and pain, and it is precisely in this way that we will think about the true meaning of life and a real ultimate question."

"Can death be avoided?"

"Kato-kun, what do you think?"

Kato Oo was silent for a long time. He almost didn't listen to what Orochimaru said. When he heard the news of Kato Haruka's death, he only felt an endless boredom and frustration that penetrated into every inch of his body, a feeling of nowhere. The pain of venting gave him the urge to destroy something.

He clenched his fists tightly, but he was so weak.

"The human body is really fragile..."

"What an amazing speech... Kato-kun."

Orochimaru stared at Kato O's lowered head and didn't know what he was thinking. He just gently shook the glass tube in his hand, with a look of reminiscence on his face.

"What is hidden here is the secret of the legendary Mu Dun..."

Kato Ou didn't know if his perception had improved as a result, or if Orochimaru had no defense against him.

For the first time, I could vaguely feel Orochimaru's emotional changes. It was similar to his sadness, a sad emotion that was slightly sad.

"Perhaps, the end of the art is eternal life..."

"This immortal cell that seems to exist forever is so fascinating..."

Orochimaru did not immerse himself in sadness for too long. He gently shook the glass tube in his hand and stared at Kato Oo again. This was a kind of enthusiasm and a bit of recognition that was different from the previous coldness and scrutiny.

"Kato-kun..."

"The immortal body and the eternal soul..."

There was a bit of temptation and depth in Orochimaru's tone, as if he was heading straight towards Kato Ou with boundless momentum.

"Can eternal life be realized..."

Kato Oo had never seen Orochimaru's eyes so bright before. The man in front of him, this slightly feminine man, although he was asking him, he never seemed to doubt the feasibility of this matter.

"I want to live..."

"I don't want to die..."

Kato O's face flushed red, and his eyes stared at Orochimaru, as if he wanted to pour out all the grievances and sufferings he had suffered over the years at this moment.

The desire buried deep in the heart is a person's most basic right to survive.

Even though his status is low, even though his life and death are currently in the hands of others, he never feels that his will to survive is weaker than anyone else.

"I... don't want to die again..."

A low voice sounded in the bottom of my heart, recalling that I was once on the edge of life and death. It was like the despair of life brought by absolute darkness. It was like an endless huge mass wrapped around him and kept shrinking, squeezing him into a ball, and making him Unable to breathe, completely suffocated.

He didn't want to experience this feeling again.
