Naruto: Starting from the Uchiha and Senju bloodlines

At the base, Orochimaru was conducting his research selflessly.

Through White Zetsu's body, Orochimaru's experiments made great progress.

For example, Impure World Reincarnation.

According to Orochimaru's research results, the dead resurrected by ordinary Impure World Reincarnation cannot exert the strength they had in life, and the gap is very large.

However, if White Zetsu's body is used as a sacrifice for resurrection, this gap will be infinitely shortened.

There is also the immortality ninjutsu studied by Orochimaru.

Orochimaru believes that if he wants to achieve immortality, he must find a way to solve the problem of the aging body.

There is a limit to the cell division in each body. After reaching a certain limit, the division rate will slow down, which will cause aging until the cells no longer divide and die.

But the human spirit does not age with the aging of the body.

So Orochimaru came up with an idea to transfer his spirit into other people's bodies, constantly changing bodies, and thereby gain eternal life.

However, during the research, Orochimaru discovered that if the spirit is transferred to another person's body, the body's cells will divide at an accelerated rate, and then when they reach their limit, they will no longer divide and will die directly.

This process will not go through the aging process, because the cells suddenly stop dividing after accelerating their division, and do not experience the process of slowing down the cell division rate.

The reason for this is that human spirit, that is, soul, is unique, and human body is also unique.

Just like a special knife, it needs a special sheath to store the knife.

If you change to another knife, you will have to modify the scabbard to store the knife.

The same is true of people and souls.

The soul fits the body, and the body fits the soul.

Suddenly the soul is replaced by someone else's soul, and the body will try every means to fit this new soul.

This is the reason why the cells in the body divide faster. Because they need to be in harmony with the soul, the body will accelerate the division of cells to make changes in order to achieve the purpose of being in harmony with the soul.

However, cell division has a limit. When the cells reach their limit and can no longer divide, the body will die and collapse.

Orochimaru had previously been trying to inhibit the accelerated division of body cells.

From being able to suppress it for a week at the beginning, to a month, and then to a year.

However, the longer you try to suppress it, the more difficult it becomes.

If it weren't for White Zetsu's body, Orochimaru might still be trying to find a way to suppress the accelerated division of cells and extend the use time of his body.

However, White Zetsu's body gave Orochimaru a lot of ideas.

Through research, it was found that if one transfers one's soul to White Zetsu's body, the body can be used for at least ten years.

Because the Hashirama cells in White Zetsu's body provide activity, they can withstand the accelerated cell division for a long time.

This White Zetsu's body is simply a universal material.

This brought new inspiration to Orochimaru.

Orochimaru already knew that among the sixty babies who were involved in the Hashirama cell transplantation experiment, only one survived, and that was Yamato.

This means that his genetic modification technology was successful.

If we use White Zetsu's body as a model and utilize genetic modification technology, cell transplantation technology, cloning technology... and other technologies to create a body that matches his soul, wouldn't that be equivalent to successful and unlimited immortality?

Perhaps the body created at the beginning was not perfect, but Orochimaru was very confident that as long as he had time, he would be able to overcome various difficulties until he achieved perfection.

However, the current Orochimaru does not have this ability.

Because some of his techniques are still immature, and Orochimaru has not officially used the immortality ninjutsu of transferring souls.

So Orochimaru plans to use this eternal life ninjutsu once first.

Only by experiencing it yourself can you know its shortcomings and make improvements.

Of the original five White Zetsu, there are still two left.

One is used for experiments, and the other is used as a reincarnation container to perform the immortality ninjutsu.

But it is still not enough, Orochimaru plans to ask Chiba for help and get a few White Zetsu for research.

Orochimaru left his laboratory and found a snake waiting at the door.

Seeing Orochimaru coming out, the snake's belly began to twist, and it opened its mouth, spitting out a ring and a piece of paper.

The ring and paper were both sticky, but Orochimaru didn't mind at all and picked them up.

There is a sentence written on the paper.

[We will take action against you tomorrow night. The ring can be used for communication. See you next time, Master Orochimaru.]

The corners of Orochimaru's lips curled up slightly.

Orochimaru did not leave Konoha, but waited for Sarutobi Hiruzen to attack him, and this day finally came.

He was trained by Sarutobi Hiruzen, and Orochimaru hoped that it would be Sarutobi Hiruzen who would end it all in the end so that he would be completely free of worries.

After leaving Konoha, Orochimaru will be very free and can do whatever experiments he wants without having to hide anything.

The reason why Orochimaru has never used the Impure World Reincarnation and Living Corpse Reincarnation even though they have almost been successfully researched is that he is worried that there may be unnecessary trouble when using them in Konoha.

This day has finally come, Orochimaru has been waiting for it for a long time.

Orochimaru put away the ring, destroyed the note in his hand, and began to put away the things in the laboratory.

...

The next evening.

At the Anbu base, Sarutobi Hiruzen has already put on ninja combat attire.

Behind Sarutobi Hiruzen stood five elite ANBU ninjas including Kakashi.

Sarutobi Hiruzen looked at the night sky that had become dark due to the setting sun and said in a deep voice: "Follow me!"

Sarutobi Hiruzen led the team and rushed towards Orochimaru's base.

A moment later, Sarutobi Hiruzen and others arrived outside Orochimaru's base.

Just as Sarutobi Hiruzen was about to go in, he was stopped by Kakashi: "Please wait a moment Sandaime, Orochimaru has set up a barrier around the base. As long as it is triggered, Orochimaru can feel it. I have seen the Thousand Feathers Seal dissolve this barrier before, so I know that method!"

Sarutobi Hiruzen nodded and said, "Okay, Kakashi, you will remove this barrier."

Kakashi was certain that Chiba must have informed Orochimaru.

Orochimaru had originally planned to leave Konoha, and Kakashi decided not to waste this opportunity and to show himself as much as possible so that Sarutobi Hiruzen would trust him more.

Kakashi quickly formed seals with his hands and pressed them to the ground.

A barrier seal appeared on the ground.

Kakashi formed a seal again and shouted, "Release!"

The barrier around Orochimaru's base was unlocked.

After the barrier was broken, Sarutobi Hiruzen led his team to invade Orochimaru's base. Under the guidance of Kakashi, they smoothly arrived at the door of the room with the sealing ritual.

Some noises could still be heard in the room, and Sarutobi Hiruzen judged that Orochimaru must be doing experiments in there.

Sarutobi Hiruzen directly broke the seal on the door of the room, broke the door open and led his men in.

Orochimaru turned and looked at Sarutobi Hiruzen, his eyes calm, and although he was smiling, there was no smile.

"Sarutobi-sensei, are you going to kill me?"
