Naruto: Sasuke Uchiha Returns from Soul Society

“A tool for revenge,” Sasuke answered without hesitation.

"Is it merely a tool?"

Kakashi shook his head. "You rely too much on your sword and those strange techniques. You seem to have forgotten that the Uchiha clan's greatest strength originates from here."

He pointed to his eyes, "The Sharingan is a mirror reflecting the soul..."

However, before he could finish speaking, he saw three jet-black tomoe slowly rotating in Sasuke's eyes.

"Three-tomoe Sharingan?! How is that possible?!" Kakashi was struck dumb, frozen in place.

"Sasuke, your eyes..."

Sasuke remained silent, calmly looking back at Kakashi with his Sharingan, which spun with three tomoe.

Then he suddenly asked, "Didn't you say that the Sharingan is a mirror reflecting the soul?"

"So, having witnessed the horrific massacre of my entire family, how do you think my soul will be affected?"

Chapter 10 Teachings

No further words are needed.

Those eyes themselves are the best answer to all of Kakashi's questions.

After such a bloody night, it seems perfectly reasonable that such eyes would be born.

Kakashi's lips moved, but in the end, he couldn't say anything.

Sasuke caught a fleeting glimpse of pity in Kakashi's eyes and couldn't help but sneer inwardly.

In fact, he awakened his Sharingan during those days of fighting in Soul Society.

However, Kakashi was unaware of these experiences, and Sasuke was too lazy to explain them.

Misunderstandings are sometimes the best disguise.

He put away his Sharingan as if nothing had happened, and asked calmly, "The test is over, right? Can we begin training?"

But the shock on Kakashi's face lingered for a long time; the three-tomoe Sharingan...

A seven-year-old child not only awakened the Sharingan, but also directly reached the mature, complete form.

what does this mean?

Another figure involuntarily surfaced in Kakashi's mind: Itachi Uchiha, hailed as a once-in-a-century genius of the Uchiha clan.

He remembered clearly that Itachi awakened his Sharingan at the age of eight, and it took him several years of training to evolve it into the three-tomoe form.

And Sasuke before us is only seven years old...

In this respect, he even surpassed Itachi back then.

"Even more amazing than Itachi..." Kakashi muttered to himself, his gaze towards Sasuke growing increasingly complex.

He took a deep breath, forcibly suppressing the shock in his heart, and got straight to the point.

“Sasuke, your talent is the best I’ve ever seen, even surpassing your brother’s, and you have these eyes.”

He pointed to his left eye. "Theoretically, you can see through and copy most ninjutsu as quickly as I can, with a learning efficiency far exceeding that of ordinary people."

He changed the subject, his tone becoming serious.

"However, you have a fatal weakness."

Kakashi pointed out the crux of the problem: "Your chakra control is really terrible."

Upon hearing this, Sasuke frowned slightly, a hint of confusion flashing in his cold eyes.

"Poor chakra control?" He repeated the sentence in a low voice, his tone clearly puzzled.

In his view, power is power. Whether it's spiritual pressure or chakra, isn't it better to be stronger? So what's the point of talking about control?

“That’s right, it’s terrible.” Kakashi noticed Sasuke’s disapproval and gave him a more direct example.

“I can sense that the amount of chakra in your body is enormous, even several times that of mine, which is also one of your talents.”

"but."

Kakashi paused, then held up one finger: "To give you an example, it would take ten units of chakra to release a single Fireball Jutsu normally."

"With my control, I might only need eight parts, or even less, to achieve the same effect, and the saved chakra would allow me to sustain the battle for a longer period of time."

He looked at Sasuke, his eyes becoming somewhat serious.

"But that fireball you just used probably consumed more than twenty units of chakra, yet its power was less than one unit. Do you understand what that means?"

Kakashi shrugged. "Having a huge amount of chakra but not being able to use it effectively will cost you your life in a real battle."

Sasuke remained silent.

Kakashi's words were harsh, but he couldn't refute them.

He recalled his days in Soul Society; his spiritual pressure had indeed increased rapidly, but when fighting against those experienced Seats, he was always the first to exhaust himself.

Those captain-level Shinigami truly possessed unparalleled mastery of spiritual pressure, far surpassing my own abilities. Whether transforming it into sword pressure or merging it with Kido, they used it flawlessly without wasting a single drop.

Madarame Ikkaku even mocked him for this, saying that his spiritual pressure was like a tattered bag that leaked air everywhere.

So that's where the problem lies?

It seems that whether it's chakra or spiritual pressure, the control of power is ultimately the same.

"Wordy."

Having figured this out, Sasuke was somewhat moved, but he still wouldn't let it go, asking, "Get to the point, what exactly do you want?"

Seeing that Sasuke finally reacted, Kakashi's lips curled up slightly under his mask.

The objective has been achieved.

"Very good, it seems you understand." He clapped his hands, regaining his relaxed demeanor.

"So, our first training exercise today is—"

He took a kunai out of his pocket, walked to a tall tree, lifted his foot, and without using any hand support, walked up the tree step by step, perpendicular to the ground.

Kakashi hung upside down on a thick branch, smiling as he waved the kunai in his hand at Sasuke below, before slashing it against the tree.

"Control your chakra and practice climbing trees."

Sasuke looked at Kakashi hanging upside down in the tree, a hint of disdain flashing in his eyes.

"Climbing trees? Is this what you call training?"

“Don’t underestimate it,” Kakashi laughed. “If you can’t even do this well, then there’s no point in talking about further training.”

Sasuke snorted coldly, offering no rebuttal, and the three-tomoe star slowly reappeared in his eyes.

Looking at the thin layer of chakra on Kakashi's feet, he began to ponder.

"Attaching chakra to the soles of the feet to counteract gravity is quite similar to the technique used by Shinigami to stand in mid-air, except that we use spirit particles."

He believed the principles were the same, so he directly mobilized his chakra and gathered it under his feet, then stomped hard on the tree trunk.

"boom!"

With a muffled thud, a large chunk of bark was crushed by his foot, sending wood chips flying everywhere.

Failed.

Sasuke frowned, then immediately realized the problem.

Spiritual pressure is pure energy, emphasizing release and explosion, while chakra seems to focus more on the stability of form.

"Shaping chakra into a suction cup-like shape, allowing it to adhere stably to the surface of an object..."

Having grasped this key point, Sasuke saw the three tomoe spinning rapidly in his eyes, and he analyzed the flow of chakra beneath Kakashi's feet.

After failing only once, he walked effortlessly to the line drawn by Kakashi.

Kakashi watched this scene with a hint of admiration in his eyes.

Sasuke didn't stop. He jumped down from the tree and, in a flash, arrived at the riverbank next to the training ground.

He glanced at the calm river surface, gathered his chakra at the soles of his feet again, and took a step forward.

A ripple spread across the water's surface as his feet landed firmly on the water.

Then, he began to run on the water, his speed increasing until he became a black afterimage.

Having accomplished all this, Sasuke's figure flashed back to Kakashi's side.

He looked up, his tone tinged with impatience: "This boring charade is over. Now, can we get down to business?"

"..."

Kakashi was speechless for a moment.

He sighed helplessly, "Alright, now that you have perfectly mastered the use of chakra, let's begin the real ninjutsu training."

Kakashi took a few steps back to create some distance, his expression turning serious.

"Watch closely, Sasuke. Your chakra nature is fire and lightning, so we'll start with fire jutsu."

"This is a C-rank ninjutsu, Fire Release: Phoenix Flower Technique!"

Kakashi quickly formed hand seals with the speed of someone who had been single for over twenty years.

"call--!"

Kakashi spat out several basketball-sized fireballs, which accurately hit wooden stakes in different locations in the distance.

As soon as he finished, he looked at Sasuke, ready to give an explanation.

However, all he saw was Sasuke's Sharingan slowly rotating.

The next second, Sasuke moved.

He raised his hands, perfectly replicating all of Kakashi's hand seals from earlier.

"Fire Release: Phoenix Flower Technique!"

Several fireballs spewed from Sasuke's mouth. Although there were still some flaws, their power and form were almost identical to Kakashi's demonstration.

Kakashi stared blankly at the scene before him, and couldn't help but raise his hand to his forehead.
