My Disciple Has Grown Up, and I Can't Tease Him Anymore

"Breaking the Uchiha Clan's long-held beliefs?"

Sasuke lowered his head and pondered the meaning of his teacher's words.

"Teacher, are you talking about Mangekyo?"

Sasuke looked up at Hagoromo and asked with a hint of speculation.

"That's right, the ancestor of the Uchiha Clan was Indra, the son of the Sage of Six Paths." Hagoromo nodded and said, "I think your father and brother must have told you something about it, right?"

"Yes, they all told me about the inscription on the monument." Sasuke pursed his lips.

"What are your thoughts?" Hagoromo sat cross-legged in front of Sasuke. The ink for the runes was specially made, so there was no need to worry.

"Absurd."

Sasuke looked directly into Hagoromo's eyes and said very seriously.

"Whether it's the Mangekyo or the Eternal Mangekyō Sharingan, both are methods of advancement that violate human ethics."

"That's right. Putting aside the Mangekyo caused by the death of relatives and friends, the Eternal Mangekyō Sharingan that requires the fusion of brothers' eyes is something that ordinary people cannot accept."

Hagoromo shook her head. Although the inscription was left by the Sage of Six Paths.

However, most of these have been altered by Black Zetsu; a mix of truth and falsehood is the most deceptive approach.

At the very least, as far as Hagoromo knows, Uchiha Itachi has already prepared to give his eyes to Sasuke.

Just like in the original story, she disregards the opinions of others and stubbornly goes her own way, relying on the power of the Mangekyo.

That's why, in such a short time, she has almost gone blind.

Before he went undercover, his eyesight was only slightly nearsighted, but now it's almost to the point of blindness, forcing him to constantly use his Mangekyo.

"And your clan's inscriptions were altered; your father mentioned this, didn't he?"

The inscription on the Uchiha Clan's monument had already warned Fugaku long ago; whether he listened or not was no longer his concern.

"I said..."

Sasuke nodded.

"And now, the one who caused this war is the guy who altered the inscription, although the teacher was also involved." Hagoromo shrugged and said frankly.

Unlike Naruto, Sasuke is different; at least there are some things that can be explained directly to Sasuke.

Sasuke's eyes widened as he stared at Hagoromo in disbelief.

Hagoromo, however, maintained the same expression and offered no explanation.

"I believe in you, Master." After a long while, Sasuke finally looked at Hagoromo and said with a serious expression.

Hearing this, Hagoromo reached out and patted Sasuke's head. "The fact that the Mangekyo requires emotional stimulation to advance isn't wrong, but it's something the Uchiha Clan has passed down for so many years."

"Your bloodline is not as pure and primal as that of your clan's progenitor."

"You must understand that Indra, being of the bloodline of the Six Paths, can be called the 'Son of God.' This is a power of innate bloodline, while his eye power represents more of an innate 'authority.'"

"Power..." Sasuke frowned slightly, pondering the word.

"That's right, according to some research, that's indeed the case."

Hagoromo Yi nodded and said, "The reason why the Uchiha Clan needs strong emotions to advance is because their bloodline power is not pure enough, which is a way for them to develop eye diseases."

"This condition is what your clan calls the Mangekyō Sharingan, a way to absorb this power, but the price is blindness."

Sasuke looked up and blinked, somewhat confused.

"That means... Indra's eyes have always been the Three-Tomoe Sharingan, and he has never had any so-called Mangekyo."

"And his Sharingan allows him to directly use the Mangekyo's abilities."

"So, teacher, you want to trace and purify Indra's Chakra through your body?" Sasuke asked thoughtfully.

"That's right, this is to allow you to return to the source of your bloodline, to let your Sharingan reach its most authentic, high-level form, so you don't have to be like your father and your brother."

"At first, the teacher also thought that your clan's Mangekyo was the true evolutionary path. Do you remember the bottle of medicine I gave you?" Hagoromo made a gesture of holding a glass bottle.

"That jar of purple potion?" Sasuke recalled that Hagoromo had indeed made him drink it.

"That bottle itself is a potion for bloodline advancement. To be honest, if the evolutionary path is correct, that potion is enough to advance you to the Mangekyo."

Hagoromo shrugged.

At the time, he genuinely believed that Sasuke would gain the Mangekyo after drinking it.

However, this was not the case. Not only did it not happen, but Sasuke's Sharingan advancement was actually delayed.

It even went so far that his left eye had Mitsudomoe, while his right eye remained at Two-Tomoe.

Although Hagoromo didn't experiment with Sasuke, he observed that... the medicinal effects were mostly absorbed by the Sharingan itself.

The medicine solidified the previously unstable foundation, and the remaining medicinal power could only advance one of the eyes to the Mitsudomoe state.

"So, the next step is to guide this Chakra out, but not to let it merge directly with the chakra; instead, we'll seal it in certain places on your body."

"Then, as you fight or gradually adapt, untie it step by step to prevent yourself from being affected by this Chakra."

So, make your own decision.

Hagoromo spoke, she rested her cheek on her right hand and waited.

"Teacher, you know me well, and you've already done all the preparations, so there's no need to ask again."

Sasuke rolled his eyes after hearing Hagoromo's words.

My own teacher clearly knew what choice I would make, yet she still deliberately said these things.

Just as Shikamaru said, it really is a bit of a perverse sense of humor.

Snap--

Hagoromo flicked Sasuke's forehead with his fingers, clearly annoyed.

That's the downside of my disciple growing up; I can't tease him anymore.

"That's basically the gist of it. If you're ready, then let's go."

Hagoromo stood up abruptly and looked at Sasuke, who was already sitting cross-legged.

"To prevent you from running out of Yin Release Chakra, I will also seal my own Yin Release within you. When you release it in the future, you will be able to use it as a stepping stone to reach higher levels."

Sasuke's heart skipped a beat. "Thank you, teacher."

"Then, let's begin." Hagoromo raised one hand and placed it directly on Sasuke's forehead, his Yin Release Chakra erupting from his right hand.

The next moment, it broke through the limitations of the physical body and entered the mental space belonging to Sasuke.

Looking at the purple Chakra in his mental space, Hagoromo rubbed his nose. As expected of Indra, he hadn't hidden it at all.

"Then, the next step is naturalization."

On the outskirts of the real world, Hagoromo and Sasuke simultaneously unleashed violent Chakra fluctuations.

It was annihilated the moment it struck the seal.
