Chapter 1 Cell Division

In a quiet apartment in Konoha Village, in the Land of Fire, a young man stood in front of a mirror, staring at his reflection with confusion and surprise.

"No way, is time travel so casual now? I just took a nap and actually traveled through time? But fortunately, I became Uchiha Sasuke. If I had become an ordinary civilian, that would have been the worst."

The young man muttered to himself.

His hair was black and shiny, short and neatly combed. His deep black eyes seemed to contain endless power and wisdom, revealing a sharp and elusive look. His face was well-defined with clear lines, showing his calmness and maturity. Although he still appeared a bit immature, he already displayed the potential and temperament to become an outstanding ninja in the future.

Just as Sasuke was sorting out his memories, a voice suddenly sounded in his mind.

"It is detected that you have traveled to the world of Naruto and awakened the memories of your previous life. You have received the blessings of Earth and the Naruto world, granting you extraordinary comprehension!"

The corners of Sasuke's mouth rose slightly, and a hint of surprise flashed in his eyes. This sudden news made him feel extremely excited and expectant.

"As a traveler, how could there be no special powers? Here it is!"

The extraordinary comprehension sounded very powerful and invincible. With such comprehension, learning anything would be extremely fast. If he had such a talent and couldn't defeat Six Paths Madara or Six Paths Obito, then he might as well give up!

By then, the entire ninja world would become his own backyard.

According to the memories in his mind, he had not yet become a Genin, which meant the plot had not yet unfolded. According to the original story, Sasuke should have gone to Orochimaru after staying in Konoha Village for a year, and then fought Itachi after two and a half years of training. This meant he had to reach the level of Kage within three and a half years to defeat Itachi openly.

Although this might be difficult for others, he was the protagonist with a special power! This would be a piece of cake for him!

But before that, there were still some "worms" in Konoha Village that needed to be cleaned up. After all, the demise of the Uchiha clan was inseparable from these people.

First and foremost was "Root Shadow" Shimura Danzo. Like the Third Hokage, Sarutobi Hiruzen, he was a disciple of the Second Hokage. He inherited the hostile attitude of Senju Tobirama towards the Uchiha clan and secretly studied the Uchiha Sharingan.

He kept saying that the Uchiha clan was extremely evil, but he was the one most jealous of the Sharingan's ability. It was truly shameless.

Next was the Third Hokage. Although on the surface, the Third Hokage seemed to be completely unaware of what Danzo did, was that really the case? As the Hokage who ruled Konoha the longest, I don't believe he knew nothing about what Danzo did and just pretended to turn a blind eye. Whether it was the unjust suicide of Konoha's White Fang, the disclosure of the Nine-Tails Jinchuriki's identity, or Orochimaru's inhumane human experiments, if there was no acquiescence from the Third Hokage, how could Danzo hide it from him?

More importantly, the beneficiaries of these events were all the Third Hokage without exception. This "strongest" Hokage was truly deserving of his title. In terms of politics, ten Danzos couldn't beat him.

As for the remaining two elders, they were just clowns. After dealing with the Third Hokage and Danzo, they wouldn't be able to cause any trouble.

Speaking of reviving the Uchiha clan, I really don't know what the original Sasuke was thinking. He only married Sakura and left just one descendant. Can this be called reviving the family? Is it because Ino's legs aren't long enough? Or Tsunade's figure not attractive enough? Why must he hang himself on one tree? Besides, the ninja world does not practice monogamy. Isn't this a pure farce?

When Uchiha Sarada marries Uzumaki Boruto, the family will be gone.

To revive the family correctly, one must marry more wives and have more children, expanding the family to revive the Uchiha clan!

Thinking of this, Sasuke's mouth corners rose again.

"It seems that I have to endure with my body. I just look at my body. The body can't resist it."

After forming a plan, Sasuke decided to familiarize himself with Chakra, the energy system exclusive to the ninja world. According to his memory, Chakra is the energy required for using ninjutsu. This energy is drawn from the 130 trillion cells of the human body, known as physical energy, and after extensive training and accumulated experience, it is converted into spiritual energy.

This also explains why a ninja's chakra has an upper limit. The cells of the human body have an upper limit, and the body energy used for mixing has an upper limit, so chakra naturally has an upper limit. The Senju clan and the Uzumaki clan have physical energy far exceeding other ninjas due to their physical constitution, which leads to the concept of "chakra reserves."

Ninjutsu draws two types of energy from the body, and after extracting the will of chakra, it is activated through the step of forming hand seals. Of course, there are techniques like Rasengan that don't require hand seals.

As for why Senju Hashirama could release ninjutsu with just a clap of his hands, that can only be attributed to Kishimoto's narrative choice.

Then, Sasuke began to extract chakra according to the method he remembered.

When Sasuke found that he could not extract a trace of chakra no matter how hard he tried, he knew his chakra was full. His body was still too small, and there were no more cells to extract.

However, if he could increase the cells in his body, wouldn't he be able to increase his chakra?

Thinking of this, Sasuke began studying his own cells. After several hours of attempts, he finally succeeded.

[You have learned the secret of human cells by understanding the chakra extraction method and combining it with the method of cell division. You have created the cell division method!]

[Cell division method: This method can be used to divide the cells in the body infinitely. The specific number is related to the cells of the practitioner himself.]

Sasuke's eyes lit up. The cells in his body became active and began to divide continuously, increasing the original number of cells by about ten times. Then Sasuke extracted chakra from these new cells.

If the original amount of Sasuke's chakra was about half a unit, then now he had about five units of chakra in his body.
