Personal Planning

Regaining his composure, Sasuke began to summarize his current situation, comparing his advantages to the Uchiha Sasuke of the same age.

1. Information: Foresight.

There is no need to elaborate on this point; it is his greatest advantage in this world.

2. Sharingan: Three Tomoe Sharingan.

When the clan massacre occurred, the original body had only awakened a single-tomoe and a double-tomoe Sharingan, and they were latent; it wasn't until four years later, during the mission in the Land of Waves, that the original body awakened the Sharingan again under a life-or-death crisis.

Yet, the current Sasuke, having experienced the same event, has awakened the Three Tomoe and can open and close them at will.

Perhaps it is because he has lived two lifetimes and possessed a special talent for mental fortitude in his previous life, combined with over twenty years of adult experience, that after merging with the soul and body of Uchiha Sasuke, he awakened the Three Tomoe Sharingan directly.

Of course, one cannot rule out the factor of the physical trauma his body's memory endured when he personally dug out his parents' eyes.

3. He possesses an extra pair of Mangekyō Sharingan and a pair of Three Tomoe Sharingan.

Both pairs are from his closest blood relatives, which will at least help him evolve into an Eternal Mangekyo in the future.

4. A talent similar to that of a sensory ninja.

This talent was innate to him in his previous life; his body's visual perception was extremely keen, and after merging with this body, it has been enhanced by more than a single degree.

In his previous life, he needed to stare intently at a camera to vaguely detect if someone was spying on him, but now, even against the Third Hokage's Crystal Ball—which has far greater stealth capabilities than a camera—Sasuke can instantly detect the Third Hokage spying on him without needing to make eye contact.

However, unlike a sensory ninja, who can use chakra to perceive the flow, position, and movement direction of chakra within a radius of several kilometers, or even tens or hundreds of kilometers, Sasuke only possesses a pure visual perception. He cannot do what a sensory ninja does, but for him right now, it is a powerful auxiliary ability; at the very least, he doesn't have to worry about being spied on or ambushed.

Roughly estimating, Sasuke has these four advantages over the original body. Because he has only mastered this body for less than five days, setting aside the Sharingan, his ninjutsu and taijutsu proficiency in his "blank" state are not necessarily stronger than the original's, at least for the time being.

After summarizing his current situation, Sasuke walked to the desk, picked up a pen, and prepared to make a simple plan.

How can I increase my strength rapidly?

What is my current goal?

After asking himself this question, Sasuke picked up the pen and wrote two sentences using a mix of Chinese pinyin and English.

Integrate the Mangekyō Sharingan, evolve into the Eternal Mangekyo!

Undoubtedly, with the Mangekyō Sharingan of his father, Uchiha Fugaku, in his possession, the most important goal and the fastest way to increase his strength is to transplant his father's Mangekyō and evolve into the Eternal Mangekyo.

To achieve this goal, Sasuke currently faces two difficulties.

1. Sasuke's own Sharingan must also evolve into a Mangekyō Sharingan before he can perform the transplant.

2. He must learn medical ninjutsu or find someone he trusts to perform the transplant surgery for him.

Looking at the words on the paper, Sasuke narrowed his eyes, lost in thought, considering how to solve these two problems.

First, let's talk about the first one: the Mangekyō Sharingan.

In the original work, the condition for advancing to the Mangekyō Sharingan is: "To know love, and to lose it."

Once an Uchiha clan member who knows love loses that intense love, the affection is replaced by an even stronger hatred. After experiencing intense pain, special chakra surges in the brain, acting upon the optic nerves, causing the eyes to change and evolve into the Mangekyō Sharingan, which reflects the heart.

Of course, there is another prerequisite: the Uchiha who knows love and loses it must also have decent innate mental talent.

Writing this, Sasuke thought of Uchiha Obito and added another line: This talent should be divided into latent and manifest.

Just after writing it, looking at the advancement conditions for the Mangekyō Sharingan, Sasuke frowned.

The talent of this body is not bad; it could even be called extremely excellent, as he is one of the protagonists, not to mention that after his fusion, his mental capacity was significantly enhanced.

But to know love and lose it?

Sasuke shook his head inwardly. His original parents died right in front of him, and he didn't open the Mangekyō under that stimulation. Moreover, he can feel that he has begun to gradually master this body; those memories have less and less influence on him. Now, when he thinks back to the scene that night, he no longer feels the heart-wrenching grief he once did.

If things continue this way, even if Uchiha Itachi were to die at his hands in the future as in the original story, he might still not satisfy the condition of knowing love and losing it.

Even if he could satisfy it, Sasuke does not want to be like the final battle in the original work, where he was "let off the hook" the entire time and had everything arranged for him, only to open the Mangekyō in that manner.

Looking at the original body, his whole life was arranged and manipulated by others—like Orochimaru, Uchiha Itachi, Uchiha Obito, and Uchiha Itachi, and Uchiha Itachi...

Finally mastering supreme power, only to find that he is the reincarnation of someone's chakra will, and that Father Sage of Six Paths had already arranged everything.

Since he has become the master of this body, he cannot follow the plans of those people, regardless of whether they are good or evil.

Do you really think you can control everything?

My life can only be decided by myself. If I do something, it is because I want to do it, not because you arranged for me to do it.

Heh...

Thinking of this, Sasuke's gaze became profound. His thoughts raced, and in just a few breaths, countless pieces of information he had obtained from the original work in his previous life flashed through his mind to solve the problem of his Mangekyō advancement.

In the manga, the Sage of Six Paths was born with the Rinnegan, and his forehead bore a mark similar to the Eye of the Moon. The Rinnegan is an evolution of the Mangekyō. In the anime, the Sage of Six Paths did experience trauma, awakening the Three Tomoe Sharingan in an instant and then immediately awakening the Rinnegan, but in the manga, he was born with the Rinnegan and did not experience any trauma.

If the manga is used as a reference...

The reason the Sage of Six Paths was born with the Rinnegan is simply because his bloodline was pure and his innate mental energy was powerful.

The Uchiha method might just be one way to advance to the Mangekyō; it is a way to cause a qualitative change in ocular power by using intense emotional stimulation to drastically increase mental energy, achieving success in one leap.

If he cannot achieve the Mangekyō through this method of instant success, then perhaps he can increase his mental energy by gathering small streams to form a vast ocean—increasing it quantitatively to produce a qualitative change step by step.

Even if things go against his wishes, increasing his mental energy is beneficial and harmless to him.

With this in mind, Sasuke wrote the words "increase spiritual energy" on a piece of paper and added a few lines below it.

Hone the will.

Accumulate experience.

Meditative practice.

These were the three methods he could think of based on his experience regarding spiritual cultivation. Of course, besides these three, he would also try to search within the Uchiha clan to see if there were any methods for increasing spiritual energy.

Having found a direction for the first problem, Sasuke turned his attention to the second: medical ninjutsu!

Sasuke's current body did not belong to a Sage Body like that of Uchiha Madara, so he could not simply plug in and use the Sharingan or Rinnegan as he pleased. Therefore, he had to solve the problem of medical ninjutsu.

According to his own memories, the Ninja Academy did not teach courses on medical ninjutsu; there were only some classes on pharmacology and nursing knowledge.

After all, the requirements for mastering medical ninjutsu were extremely high.

First, a deep understanding of human anatomy.

Second, extremely precise chakra control.

Third, mastery of Yang Release chakra!

The founder of medical ninjutsu was Senju Hashirama. Senju Hashirama used special techniques to inject the life force of Yang Release into patients, stimulating their cells to heal wounds. Through changes in form, it could also be used for detoxification or even attacks.

Yang Release chakra sounded high-end, but in reality, it wasn't quite so. The Multi-Size Technique of the Akimichi clan was a form of Yang Release ninjutsu, and medical ninjutsu was also a branch of Yang Release.

What was truly high-end was the Six Paths Yang Power, not Yang Release itself.

The Uchiha clan inherited the Yin Power of the Sage of Six Paths, but that did not mean it was impossible for Sasuke to develop the Yang Release attribute. Yang Release chakra was equivalent to life force, and to some extent, it included the physical energy that made up chakra.

However, physical energy was not equal to Yang Release chakra. Since it was chakra, it must be the fusion and refinement of physical energy and spiritual energy; it was just that Yang Release chakra was primarily composed of physical energy.

The physical energy of the Uchiha clan only seemed weak compared to the Senju or Uzumaki, but compared to others, it was truly much stronger.

I just don't know if my Yin Release chakra will suppress the Yang Release, preventing me from mastering the Yang attribute.

Sasuke pondered secretly. It seemed that even up until the final battle, Sasuke's attributes in the official databooks did not include the Yang attribute.

You have to realize, at that time, although his body was not as strong as Naruto's Six Paths Sage Body, it was still far stronger than an ordinary Sage Body. Furthermore, he had awakened the Rinnegan, which symbolized the unification of all things. Why would the official databooks still note that his original body lacked the Yang attribute? Was it a retcon? Or was it intentionally meant to highlight the difference between Naruto and Sasuke?

He would set the third point aside for now and focus on mastering the first two. Even if he didn't end up mastering medical ninjutsu, by that time he would at least possess medical skills, making it easy enough to perform an eye transplant on himself.

After writing it down, Sasuke summarized his plan into two points.

Increase spiritual energy.

Master medical ninjutsu, at least enough to perform an eye transplant on himself.

After running through the details of the plan in his mind, Sasuke burned the paper.

"Who writes a diary if they're a serious person?"

Sasuke mocked himself. Even though the text above was written in a mix of pinyin and English, there was still a possibility of it being exposed or deciphered. Being someone who was cautious about everything, he burned it anyway.

After finishing all this, Sasuke took off his clothes and went to bed to rest.

The school exams were missed during the time I was unconscious. For these next two months, I can stay within the clan and don't have to go to school, which actually saves me some trouble.

After I wake up tomorrow, I'll see if I can find some cultivation texts within the Uchiha clan.
