There are still a few days until Tsunade officially takes office as Fifth Hokage. Kakashi and Sasuke are still lying in the hospital recovering. Konoha's reconstruction work is progressing in an orderly manner. The streets and alleys are full of busy craftsmen and ninjas carrying materials.
Team 7 has no tasks assigned for the time being, but Naruto is very free.
He quietly separated out a Shadow Clone Technique in the apartment and asked Shadow Clone Technique to stay at home with Karin to familiarize himself with Konoha's environment, while he activated Flying Raijin Technique.
With a flash of golden light, the next moment Naruto appeared in the huge cave behind the waterfall.
Everything is as usual inside the cave.
Naruto used Good and Evil Perception to scan the surrounding area and confirmed that there was no abnormal Chakra signal.
He walked to the center of the cave and sat down, then took out two things from his ninja bag.
A Sealing Scroll, Mangekyō Sharingan with Shisui Uchiha sealed inside.
A small glass dropper bottle contains a drop of red blood.
Looking at the blood in the glass bottle, Naruto couldn't help but think of the scene when he asked Karin for this drop of blood after dinner last night.
At that time, Karin was drinking tea in a chair. When he heard himself asking if he could give her a drop of blood for research, he was stunned for a moment and tilted his head with a puzzled expression.
Naruto expressed that he wanted to study the bloodline characteristics of Uzumaki clan, and maybe he could find a way to improve Uzumaki Constitution.
Karin didn't think much after hearing this, and without hesitation stretched out his index finger to let Naruto take blood.
Naruto put the blood into a small glass bottle and put it into the ninja bag.
Karin took his finger back and put it in his mouth, and the pinhole wound healed. He then continued to drink tea while holding the cup, and asked by the way if he could have salt-grilled saury for breakfast tomorrow.
Naruto looked away from the glass bottle, his eyes focused. "Absolute Control, I hope you don't disappoint me!"
After confirming that his Absolute Control was Conceptual Level, Naruto felt that he was wasting this ability in his previous life.
Controlling your own body and cells is actually the most basic method.
If we dig deeper, is it possible to control the internal contents of body cells?
The most intuitive thing is the cancer cells that frighten ordinary people. As we all know, the number of normal human cell divisions is limited. Every time the telomeres divide, the telomeres shorten. After shrinking to the limit, the cells stop dividing and undergo apoptosis. This is aging in the biological sense.
But cancer cells are different. The telomerase of cancer cells is abnormally activated, and telomeres do not shorten with division, so cancer cells can divide indefinitely.
If you can use Absolute Control to precisely control the telomere length and telomerase activity of every cell in your body, and allow normal cells to acquire unlimited division capabilities similar to cancer cells without losing control, then theoretically you can achieve immortality.
However, these are the scientific thinking frameworks of past lives. Immortality is nothing new in Shinobi World, a world with Yin–Yang Release and reincarnation techniques.
Orochimaru relies on Living Corpse Reincarnation to change his body to extend his life in disguise, Sage of Six Paths relies on Yin–Yang Release to extend his existence for thousands of years on the Chakra level, and Kaguya-hime will not die even if he is directly sealed.
However, what Naruto wants is not to achieve immortality through magic, but to achieve natural immortality that will not be eroded by time while possessing absolute strength.
Today is the first step to verify this series of conjectures.
Naruto first picked up the small glass bottle containing Karin's blood.
He did not rush to open the bottle cap, but opened Absolute Control first and let his consciousness sink into his body.
In the state of Absolute Control, Naruto can clearly "see" every minute structure in his body.
Every opening and closing of a heart valve, the path of blood rushing through arteries and veins, and the bioelectrical signals jumping on nerve endings.
Without stopping, Naruto continued to sink his consciousness downwards, constantly raising the accuracy of perception.
The millions of cells in the blood gradually become clearer in the field of vision. The red blood cells are like flat discs floating in the plasma, while the white blood cells are larger and rounder with irregular bulges on the surface.
Although I often control the cells in my body, this is the first time I can "see" my own cells.
Without stopping, Naruto passed his consciousness through the cell membrane and cytoplasm of white blood cells, all the way deep into the nucleus.
Here Naruto saw his own genetic sequence.
The double helix structure is coiled on the chromosome in an extremely elegant manner, and the base pairs are arranged in a long chain.
Naruto memorized his complete genetic sequence in his mind, and then exited this deep microscopic state of perception. He opened his eyes and let out a breath.
This level of Absolute Control consumes mental energy significantly higher than regular use, but it is still within a controllable range.
The level of consumption is roughly equivalent to the level of sorting out the memory after practicing two hundred consecutive Shadow Clone Techniques, and is far from the point of damaging the fundamentals.
This also proves that there is some consumption in casting Absolute Control, not Chakra, but his mental power.
However, the frequency of daily use of Absolute Control is limited, and the recovery speed of mental power is much faster than the speed of consumption, so I have never felt obvious mental exhaustion.
Naruto set his sights on Karin's blood.
With a thought in his mind, a small cut slowly opened in the palm of his right hand.
Open the lid of the glass bottle, and Naruto blood drips into the incision in the palm of your hand.
The moment the blood comes into contact with the capillaries in the body, Naruto seals the incision on the palm, and the skin heals again without leaving even a trace of scar.
At the same time, Absolute Control raised the perception accuracy to the genetic level again at the same time. The white blood cells in Karin's blood were immediately locked by him after entering Naruto's blood.
The complete genetic sequence of Karin can be clearly seen through the cell nucleus Naruto.
He compared the sequence of Karin with his own sequence side by side. There were a large number of highly similar parts between the two sequences, which confirmed that they were both bloodline heirs of Uzumaki clan.
But there are also some completely different sequence fragments. These differentiated fragments are most likely the key codes of Karin that are different from its own sequence.
Naruto did not hesitate at all, and directly used Absolute Control to start Fusion the different fragments in the Karin gene sequence with his own genes.
The gene sequence Fusion proceeds in an orderly manner under the precise control of Absolute Control, and the substitution of each base pair is strictly limited within the controllable range.
Soon the changes at the genetic level triggered a reaction in his body.
The most obvious thing is that the body temperature begins to rise sharply.
Naruto could feel that the cells all over his body were adapting to the new genetic code. The frequency of metabolism was stretched to the limit in a short period of time. Fine beads of sweat began to leak out from the surface of the skin. The sweat quickly evaporated into a thin layer of white mist in the cold air of the cave.
Naruto keeps running Absolute Control with its eyes closed, closely monitoring the changes in every cell in the body.
If there is any abnormality, he will immediately terminate the Fusion process and remove the mutated cells directly from the body.
Time passed by minute by minute, and the cave was so quiet that only the roar of the distant waterfall penetrating the rock wall could be heard.
After about half an hour, the persistent fever gradually subsided.
The moment the last mutated cell completed Fusion, Naruto clearly felt a huge Chakra bursting out from his body.
It's like a valve that hasn't been opened in more than ten years has been unscrewed.
