Naruto: Creating Immortal Techniques at Six, Shocking Uncle Snake

Chapter 56: The Birth of a New Mangekyō! Side Effect: Lifespan Reduction!

After digesting the information in his mind, Ishihara narrowed his eyes.

His hypothesis was correct.

To evolve from the Three Tomoe Sharingan to the Mangekyō Sharingan, the key lies in the transformation of Yin Release chakra, which mutates specific organs after an emotional outburst.

The Mangekyō training method involves continuously accumulating Yin Release chakra to trigger changes, causing the special organs to mutate!

In other words, it simulates the process of emotional outburst, thereby unlocking the Mangekyō Sharingan!

Quantitative changes lead to qualitative changes!

This thought flashed through Ishihara's mind, and then he had a sudden idea.

"Is it possible to skip the first process and directly stimulate the organs for targeted mutation?"

He shook his head afterward. That would be bioengineering, not training.

Moreover, inducing targeted mutations is extremely difficult; he doesn't yet have the necessary knowledge for that.

"But if that's the case, this secret technique still doesn't meet my requirements."

Ishihara furrowed his brows.

His goal was to have several Uchiha members unlock the Mangekyō Sharingan in a short period of time.

However, the Mangekyō training method requires extensive practice, spanning ten or even decades.

It clearly doesn't meet his needs!

"I must shorten the time to unlock the Mangekyō!"

Ishihara once again fell into deep thought.

The technique has two components that can shorten time: the amount of Yin Release chakra and the growth of the special organs.

"My research on Yin-Yang Release is still too shallow. Breaking through in Yin Release in the short term seems impossible."

"Then I'll focus on accelerating the growth of special organs!"

With this direction in mind, Ishihara's thoughts became instantly clearer, forming a rough framework.

His previously acquired extensive knowledge of medical ninjutsu became extraordinarily active.

Stimulating cell growth was something Orochimaru frequently did during his forbidden experiments, so Ishihara had no shortage of knowledge in this area.

With these insights, the framework in his mind gradually filled in.

Finally, it became complete.

Ishihara let out a long breath, a smile appearing on his face.

[You have improved the Mangekyō training method based on your medical knowledge, creating the secret technique: Mangekyō Training Method 2.0.]

[Mangekyō Training Method 2.0: After mastering it, one can unlock the Mangekyō Sharingan. However, the side effects are severe, drastically shortening the user's lifespan!]

Despite the severe side effects, Ishihara was extremely satisfied.

After all, it's not him who would use this technique, nor is it his lifespan being shortened.

As long as it significantly reduces the time required to unlock the Mangekyō Sharingan, that's enough!

Besides, he wouldn't be using either version of the training method himself—improvements are still needed.

Cough, cough...

At this moment, a sudden coughing sound echoed.

Ishihara looked down to see that the three Uchiha members he had captured were waking up.

He gestured towards the three of them and the Fugaku lying on the operating table.

"Alright, my research on you is over. You can leave now!"

It's over?

No need to extract their eyes?

Isn't this too casual?

Fugaku was a bit dazed, feeling that everything was not as he imagined. He couldn't help but ask:

"Have you figured something out?"

Ishihara looked at him with a half-smile.

"If I told you that I've developed a secret technique to unlock the Mangekyō Sharingan, would you believe me?"

Impossible!

The words were about to slip out of Fugaku's mouth.

But he suddenly remembered the information Itachi had mentioned.

Back then, Ishihara had unlocked the Sharingan in an extremely short period.

Could it be true?

Fugaku suddenly came to his senses, and with a trembling voice, he asked:

"Wait, are you saying that this secret technique can be used by anyone?"

Ishihara smiled and nodded.

He was in a good mood, having developed the Mangekyō training method so quickly, and didn't mind explaining a bit more.

"But the most suitable candidates are still those in the Uchiha clan who have already awakened the Three Tomoe Sharingan. However, the side effects are significant!"

Fugaku's eyes instantly became fervent!

He believed Ishihara wouldn't deceive him because there was no need to!

If the Uchiha clan could obtain such a training method, how terrifying would they become?

Two, three, or even more Mangekyō Sharingans!

Would the Uchiha clan still face difficulties in Konoha then?

Not a chance!

As for the side effects, who would care when they can unlock the Mangekyō Sharingan!!!

Fugaku trembled with excitement, opening his mouth to ask but unsure of how to proceed.

He seemed to have no leverage for negotiation.

Ishihara glanced at him without speaking and left the room.

Although he really wanted several pairs of Mangekyō Sharingans, it wasn't him who needed to make the first move. It was the Uchiha clan, who were eager to change their unfavorable position in Konoha.

There was no way he would initiate the discussion!

Even if Fugaku guessed his intentions, he wouldn't outlast Ishihara.

After Ishihara left, the three Uchiha members, who had remained silent, finally dared to speak.

"Captain, who exactly is this Ishihara, and how strong is he...?"

Uchiha Tetsuka hesitated to continue.

Earlier, the three of them combined couldn't withstand even a single move from Ishihara; they were trapped in a genjutsu right after meeting him.

This level of strength left them in shock.

Not to mention that they had personally witnessed Fugaku, who had unlocked the Mangekyō Sharingan, being defeated by Ishihara.

Facing such a powerful figure, they naturally knew to behave submissively and follow orders.

Fugaku sighed upon hearing this and then shared what he knew about Ishihara.

"He's only six years old?"

Uchiha Tetsuka and the other two were dumbfounded, unable to find words to express their shock.

The room fell silent.

After a long while, Uchiha Tetsuka asked, "Then why did you come to him, Clan Leader?"

Fugaku furrowed his brows at the question and, after a moment of hesitation, spoke with a heavy expression:

"One of my Mangekyō abilities is to foresee future trends based on current information."

"Through this ability, I discovered that the Uchiha clan faces the danger of extinction!"

What?!

The three Uchiha members' faces immediately turned pale.

Fugaku remained silent.

In those two visions, he saw not just the outcome but also the attitudes of the Third Hokage, Danzo, and other high-ranking members of Konoha toward the Uchiha clan.

It wasn't just suppression.

It was total annihilation!!!

As this thought crossed his mind, a surge of killing intent welled up in Fugaku's heart.

He would never let the annihilation foreseen in his visions become reality!

Fugaku clenched his fists, looked at the three of them, and said in a deep voice:

"But if we can cooperate with Ishihara, not only can we avoid the crisis of extinction, but the Uchiha clan can also rise to the pinnacle of the ninja world once again!"

Although reality differed from his visions, Fugaku was not disheartened. On the contrary, he was even more excited and determined to cooperate with Ishihara.

Because Ishihara was far more powerful than he had anticipated!

His ability to develop secret techniques was also more terrifying than he had imagined!

If they could reach an agreement, the future of the Uchiha clan might be even stronger than what he had foreseen!

"You probably heard it earlier as well. He has developed a technique that allows people to unlock the Mangekyō Sharingan!"

"Trust me, it's real!" 

"So, we have to cooperate with Ishihara!"

Upon hearing this, the three members of the Uchiha trio looked at each other in silence.

They had also overheard the conversation earlier, and it was impossible not to be excited or tempted by what they heard. However, when they considered Ishihara's strength, they immediately calmed down.
