Naruto: Immortal Spirit

"Sharingan... what secret is hidden..."

In Ryūchi Cave, Kato Oo looked at the Sharingan in the glass test tube.

The dark magatama in the blood-colored eyes seemed to swallow up all the light. It was the ultimate black depth.

The experimental subject lying on the experimental table beside him had fallen into an endless sleep due to the soul inactivation process.

A healthy body and a strong figure are materials that make every researcher in the ninja world shine.

He didn't know where Orochimaru found such a nearly perfect experimental subject. Orochimaru had his own channels for obtaining experimental subjects, and he never asked.

"The recipient transplant experiment is ready..."

The deep voice of another Kato Ou who was busy on the research table made the other four Kato Ou in Ryūchi Cave all focus on the experimental table.

"Start transplantation..."

Standing in front of the huge screen, Kato Ou gently put down the test tube in his hand. A thought crossed his mind, and the other five clones quickly began to carry out the actions in their hands in an orderly manner.

All the monitoring instruments were quickly connected to the experimental subject, and the chakra scalpel in his hand suddenly passed through his eye sockets.

For Kato Ou, who has long been proficient in the meridians of the human body, changing a pair of eyes is not a difficult task with the help of chakra.

Receiving the images in the sight of five clones at the same time, Kato Oo's brain was running rapidly.

His mental energy intensity was countless times higher than that of an ordinary jounin, but he did not feel any discomfort.

As the gleaming green light of the Palm Immortal Technique in the clone's hand slowly lit up in the Longdi Cave Laboratory, Kato Oo stared closely at the various data on the display screen - they began to fluctuate violently.

"Connect the consciousness of the experimental subject, mobilize the chakra into the Sharingan, and transmit the perception at the same time..."

A finger of the clone gently placed on the forehead of the experimental subject. The moment the soul sense entered the experimental subject, Kato Oo felt an extreme sense of emptiness.

Although it is only the Sharingan of the twin magatama, it is like a bottomless pit, extracting the chakra from the whole body of the experimental subject.

"Can't you close the Sharingan...

Then this kind of organ that constantly consumes chakra is a heavy burden on the body, both mentally and physically..."

"Excessive consumption of mental energy can lead to malaise or even coma, while excessive consumption of physical energy...can lead to loss of vitality..."

Kato Oo slowly closed his eyes and focused all his sensory abilities on the experimental subject through the soul link built by the clone.

"Yin escape chakra is continuously synthesized through chakra in the meridians of Sharingan...

But...why is it not Yang Escape Chakra synthesized by physical organs? "

Some inexplicable inconsistencies puzzled Kato Ou.

Compared with the traditional spiritual energy that contains the power of Yin escape, and the physical energy that contains the power of Yang escape, in the blood line of the Uchiha clan, it is exactly the opposite...

"However, the Sharingan is indeed the bloody treasure of Konoha... it is really powerful enough... even if it is just a pair of magatama..."

The dynamic vision brought by the Sharingan gave Kato Ou an unprecedented experience, and the whole world began to pass before his eyes like frame by frame.

If you are familiar with ninja taijutsu combat, you will know what kind of combat bonus this ability will bring to an ordinary ninja.

"Start the second set of comparative experiments to verify the changes in Yin Escape energy intensity between the three Magatama Sharingan and the double Magatama Sharingan..."

The five clones got busy. Kato Ou slowly walked down the experimental table, replaced the clone and placed his left hand on the head of the experimental subject.

All the spiritual power surged into the experimental subject's head. Although the experimental subject was no longer conscious, his face seemed to be twitching instinctively, and his bright red eyes seemed to burst out...

"If the spiritual energy is only multiplied, will the intensity of Yin Escape change..."

"three times……"

The mental energy is supplied by Kato Oo, while the physical energy is completely squeezed out of his own cells.

The subject's body began to twitch, and foam began to form at the mouth, as if it could not withstand such an intensity of chakra withdrawal.

"Five times..."

The entire experimental platform began to vibrate due to the violent distortion of the experimental object. All the clones stopped their movements and looked at the experimental object on the experimental platform.

The double Magatama Sharingan also seemed to be filled with a huge amount of Yin Escape Chakra, and the speed of withdrawing Chakra began to slow down.

"Eight times...nine times..."

Feeling that the sharingan's withdrawal of chakra became slower and slower, Kato O's eyes became brighter and brighter.

However, the entire experimental subject seemed to have completely stopped moving, and the cells in the body began to shrink, but in an instant it seemed to be reduced to skin and bones.

"ten times!"

The final mental impact seemed to completely break some barriers. Kato Oo felt as if he had bottomed out, and a more violent suction came in like a whale.

Before Kato Ou could increase the intensity of his mental energy again, all the cells in the subject's body seemed to have died in an instant, and no physical energy could flow out.

Only the Sharingan eye, which was as red as blood, grew on the flesh and bones, like a bloody rose blooming on the dark earth, and only a pair of bright red eyes radiated red light in the darkness.

"Take out the Sharingan..."

Sighing slightly, Kato Oo frowned slightly. The secret of the body and spirit seemed to be right in front of him, but he felt helpless.

He seems to need an unknown thing to connect all things...

"One of the key steps in reincarnation is to separate the soul from the body without the death of the body."

"Second, the separated soul reconnects with the new body."

"Through the improvement of spiritual transformation, the will contained in the soul energy can be separated. Even if some soul energy is lost during the reincarnation process, the consciousness will not be harmed..."

"But how are the soul and the new body, Yin Escape and Yang Escape, connected, and how can the original soul be perfectly integrated into a new body..."

Kato Oo paced back and forth in the laboratory of Ryūchi Cave, thinking carefully about the secrets.

"The Yin Escape Chakra is born from the physical organs.

The Sharingan...must contain the secret of the transformation of yin and yang! "
