Naruto: Immortal Spirit

"Kato-kun, maybe sometimes we need to use our lives as a bet to survive, are you right?"

In front of Orochimaru and Kato Ou were rows of green glass containers. The emerald green solution seemed to be full of life, and they supported the experimental subjects in them.

In two years, Kato Oo really came into contact with the core content of the experiment for the first time.

"The fusion of pillar cells and the inductive experiment of wood escape..."

Kato Ou gently threw himself in front of a glass container, stared at it in a daze, and couldn't help but clenched his fists.

"Master Orochimaru..."

He couldn't bear it. Such a fate seemed too cruel for these experimental subjects.

"Has Kato-kun shown compassion... He is really kind..."

"There is no point in lamenting the dead. If death has any meaning, it exists only insofar as it can be used."

"Human beings are really hypocritical animals. If there is a justifiable reason, then even you can deceive yourself."

"Kato-kun has never treated criminals like this before..."

On the flat dark ground, a drop of sweat dropped, and Indifferent fell into eight petals on it.

"But, these... are still children..."

"It's really interesting... Kato-kun, you remind me of someone, someone as innocent as you..."

"You should have heard his name, a fool named Jiraiya..."

"Like you, he felt compassion for the three children and even taught them for three years..."

"It's stupid..."

Orochimaru's cold snake eyes stared at Kato Oo, and a strong murderous aura swept over him.

"But compared to that idiot, it seems that Kato-kun has forgotten his identity and the life at his roots..."

Kato Oo clenched his fists and half-knelt on the ground. The air in the entire laboratory seemed to be stagnant, and the biting ice edges that seemed to have turned into substance penetrated his body in an instant, nailing him to the ground.

He knew that he shouldn't show too many other emotions. Emotions were the biggest enemy of a tool like a ninja.

"Now, Kato-kun should know how to do it..."

He could imagine the consequences of this level of secret work if it were made public. Now he couldn't tolerate any thoughts of quitting. Instead of pitying others, it was better to pity himself.

"Yes, Lord Orochimaru! Kato Oo will do his best..."

"Let them live too..."

"Hahaha, Kato-kun, it seems you are very confident in yourself..."

Orochimaru's eyes were faint, but he did not let him immediately invest in research. He just led him to move around at will in this more secret experimental base, which was completely hidden in the deepest part of the root.

"The fusion fluid used by the one hundred experimental subjects in the entire experimental base was all prepared by Kato-kun."

"I don't know, if they die due to the incompatibility of the fusion fluid, should Kato-kun be blamed..."

"I will prepare the fusion fluid individually for each experimental subject..."

Kato Ou lowered his head. He had an inexplicable delusion, as if he had become someone's accomplice unknowingly.

But he just wants to live well...

"Kato-kun really does have a kind heart..."

Orochimaru's somewhat gloomy eyes lightly glanced at these experimental subjects without saying anything else.

"Then the growth records of these experimental subjects will be handed over to Kato-kun... I hope to see good results..."

Orochimaru's back slowly fell into the black shadow. Kato O looked at his back and couldn't help but yelled.

"Lord Orochimaru! Is this... the request of Elder Danzo..."

"If Kato-kun needs to attribute all his sins to a certain target and make himself feel more at ease, Elder Danzo is indeed a good target."

Orochimaru didn't pay attention to Kato Oo's words, he just smiled softly, his eyes swept around the laboratory, and finally fell on Kato Oo.

"Kato-kun, you should try to understand the reality of this world. The road to pursuing immortality is doomed to cruelty and bloodshed. Without such an awareness, you are really too naive..."

"Just like this, has your will been shaken..."

"If you have enough strength, you can dominate the world according to whatever you want, what do you think, Kato-kun..."

Half of Orochimaru's body was hidden in the darkness, and his whole body was like a poisonous snake waiting for an opportunity to move out of the shadows, which made Kato Ou feel a sense of gloom and coldness.

Snakes are indeed cold-blooded animals. Kato Ou has never sensed such a capricious person. During this period, he could often feel Orochimaru's murderous intent. It seemed that Orochimaru was also at a critical moment of tangle.

"Lord Orochimaru, I will live, I have to live forever..."

Kato Oo suddenly raised his head and stared into Orochimaru's eyes.

"Hahaha, I look forward to the day when you change the world. If possible... Kato-kun..."

A scroll was thrown to Kato Ou by Orochimaru. Orochimaru didn't say much, just smiled softly, with a cold and cruel smile.

"However, it seems that Kato-kun should solve the trouble in front of him first..."

"The third of the three ways to solve the curse seal, and the most likely thing Kato-kun can do, is to use the sealing technique to seal the curse seal so that the curse seal cannot sense any external chakra."

"I'm looking forward to what Kato-kun will do after he resolves the curse seal..."

Orochimaru seemed to have a bit of bad taste, and also seemed to be playing tricks on a small animal, with a bit of interest, and disappeared into the deepest research room at the root.

Kato Ou grabbed the scroll and silently watched Orochimaru disappear into the shadows. The deep green light from the research room reflected in his eyes, shining with an inexplicable look.

"Sealing technique..."

The scroll records the most basic knowledge of sealing techniques, which Kato Oo has never been exposed to before, but it is also what he needs most now.

Kato Ou silently placed the scroll recording the sealing technique in his arms. He opened the cell analyzer in the laboratory and put the experimental cell numbered 001 into it.

Configuring a separate fusion fluid for each experimental subject is an arduous project, even if he now knows every detail and characteristic of the fusion fluid.

"Chakra analysis shows that the maximum density of chakra in a single cell has increased to 50% of the original..."

Kato Oo breathed a sigh of relief. If it was this level, it should have barely reached the minimum physical limit for transplantation.

Slowly walking up to Experimental Subject No. 001, he could see their faces clearly through a huge glass cabin.

"Partially spiritualized!"

He pointed his finger on the glass chamber, and a faint fluorescent light stretched out from his finger, as if in another space, without affecting any physical matter, and entered the eyebrows of the experimental subject.

"Find the mental fluctuation..."

"The spiritual energy seems to be increasing..."

"But, it's not enough..."

According to his understanding of Hashirama cells, Hashirama cells are more terrifying for mental suppression than physical acceptance.

These pillar cells can continuously proliferate themselves, and the fundamental reason for maintaining this violation of biological principles is a manifestation of the cells' instinct to stimulate chakra.

Although it is still unknown where the spiritual energy used by these cells to synthesize chakra comes from, this is also the biggest secret of Hashirama cells.

Orochimaru seemed to know something, but it seemed like he had no intention of telling him.

Kato Oo was a little depressed. If this was the root cause of the fusion, there was nothing he could do. He could only rely on the increase in spiritual energy brought by these children's own desire to survive.

"I need to know this secret to save them..."

According to the degree of erosion of Hashirama's cells, their increased mental power cannot suppress Hashirama's cells for long. Hashirama's cells will explode instantly in the near future, even with the gain brought by the fusion fluid, it will not help.

Kato Ou recorded the physical state and mental energy range of each experimental subject, and equipped them with the most suitable proportion of fusion fluid according to their physique.

Three months have passed...

The first failure case also broke out...
