Naruto: Creating Immortal Techniques at Six, Shocking Uncle Snake

"But how can we get him to cooperate with us?" one of them asked.

Fugaku's expression stiffened when he heard this and he let out a sigh.

"In my calculations, I would have to offer him my Mangekyō Sharingan abilities and the future Mangekyō Sharingan techniques that Itachi will unlock for his research!"

"And I would also have to give him access to the Uchiha clan's secret and forbidden techniques!"

As soon as he finished speaking, the expressions of the Uchiha trio changed dramatically, and they shouted in anger:

"No way!"

They were proud members of the Uchiha clan.

To willingly become experimental subjects for someone else's research was utterly absurd!

Their pride and dignity simply couldn't accept it!

Seeing the trio's anger, Fugaku also became enraged and growled:

"You think I want to do this?"

"I am the head of the Uchiha clan, the most powerful clan in the ninja world, and one of the most influential figures in the ninja world!"

"Even against the Third Hokage, I dare to stand my ground!"

"If there were even the slightest possibility, do you think I would willingly become someone else's research material?!"

"Everything I'm doing is for the sake of the clan!!!"

The trio fell silent upon hearing this.

Such humiliation was hard for them to accept.

But when faced with the choice between the annihilation of their clan and losing their dignity to protect it, they were also willing to sacrifice for the sake of the clan!

The three exchanged glances, their eyes growing resolute.

"Clan leader, go and negotiate with him!"

Seeing this, Fugaku felt a sense of relief.

At last, he had gained the understanding of his clan members.

This made him feel a little lighter, despite the immense pressure and shame he had been carrying.

"Alright, I'll go talk to him!"

Fugaku nodded, then walked out of the room.

As he approached Ishihara, who was resting under the shade of a tree, his emotions were extremely conflicted. He sighed deeply as he walked up to him.

"I want to cooperate with you."

Ishihara raised an eyebrow and asked with interest, "What do you have in mind?"

Fugaku took a deep breath, his expression becoming serious.

The conversation that followed would determine the fate of the Uchiha clan, so he had to be cautious.

"If I'm not mistaken, your goal is probably the Mangekyō Sharingan of the Uchiha clan, or perhaps our Mangekyō abilities, right?"

After saying this, Fugaku nervously watched his reaction.

"That's one of my objectives," Ishihara replied with a smile, nodding without denying it.

Fugaku was taken aback for a moment. He hadn't yet figured out what other goals Ishihara might have, but he felt a bit relieved. As long as he still had bargaining chips, they could negotiate.

Swallowing hard, Fugaku nervously said:

"I can give you all of the Uchiha clan's secret and forbidden techniques!"

"But in return, you must help my clan members awaken the Mangekyō Sharingan. After they awaken it, their Mangekyō will be available for your research!"

Ishihara looked at him in surprise.

He hadn't expected Fugaku to make such a bold offer.

He was even more surprised that Fugaku was willing to set aside the Uchiha's pride.

However, this indeed made it easier to advance his own plans.

"Alright!"

Ishihara readily agreed, smiling as he added:

"To show my sincerity, today I can help one of your three subordinates awaken the Mangekyō Sharingan!"

He wasn't concerned about Fugaku's schemes; his secret techniques were not so easily obtained.

"Deal!"

Fugaku was visibly shaken; he hadn't expected Ishihara to agree so readily.

Excitedly, he called the three members back into the room.

After a heated argument, it was ultimately Uchiha Tetsuka who stepped forward, becoming the guinea pig.

Seeing his solemn expression, as if he were about to march to his death, Ishihara couldn't help but shake his head.

"Let me explain first: the side effect of awakening the Mangekyō is a significant reduction in your lifespan. Even if the secret technique fails, you will still lose some of your lifespan, and you might even die. Are you sure you want to continue?"

Lifespan reduction?!

Fugaku and the others turned pale.

They hadn't expected the side effects to be so severe.

Uchiha Tetsuka trembled, his face turning slightly pale, but he still said firmly:

"Please proceed. How could one awaken the Mangekyō without paying any price? I've already made up my mind!"

"Very well!"

Ishihara nodded, "Sit cross-legged in front of me."

Uchiha Tetsuka sat down, his expression tense.

Ishihara cast a barrier to envelop the two of them, isolating their voices. Only then did he speak:

"Next, I'll explain the secret technique to you. Listen carefully and learn it thoroughly..."

The secret technique wasn't particularly difficult to grasp, and it could even be described as somewhat simple and crude.

As Ishihara explained, Uchiha Tetsuka gradually understood the technique.

However, he only knew how to perform it; the principles behind it remained a mystery to him, as Ishihara had deliberately concealed them.

"You'll be the first to try cultivating this technique, so I'll lend you a hand!"

Uchiha Tetsuka nodded, his expression solemn as he began to activate the secret technique.

Buzz—

Ishihara activated the genjutsu space, instantly enveloping Uchiha Tetsuka.

The sudden sensation caused Uchiha Tetsuka to shudder.

"Don't move; this is part of the secret technique!"

Ishihara's voice calmed Tetsuka, suppressing his body's instinctive resistance, though he still felt uneasy.

He didn't notice the gleam in Ishihara's eyes behind him.

"Your goal is to replicate all ninjutsu, remember that!"

The genjutsu space activated, and Ishihara planted a seed in Uchiha Tetsuka's mind.

This was Ishihara's second objective.

He wanted to push his Sharingan secret techniques to the limit, fully developing all three basic abilities of the Sharingan.

However, he had always struggled with the ability to replicate ninjutsu.

Thus, he came up with the idea of using Mangekyō techniques to reverse-engineer this ability.

This was his first attempt.

As for whether it would succeed, he wasn't certain.

After making all the necessary preparations, Ishihara quietly instructed:

"Begin operating the secret technique!"

"Yes!"

Uchiha Tetsuka immediately began activating the technique.

Suddenly, a wave of excruciating pain swept over him, causing his expression to change dramatically.

Ishihara, using his Byakugan to observe Tetsuka's condition, quickly reminded him:

"This is the secret technique draining your life force. Hold on!"

He could see that as Tetsuka's chakra rapidly depleted, the resulting emotional pain began to coalesce, leading to subtle changes in his Yin Release chakra.

Normally, such minor changes wouldn't trigger a secondary mutation in an organ.

However, under the influence of this life-draining process, the organ in question seemed to become extraordinarily sensitive.

These subtle changes immediately triggered a transformation in the special organ.

Seeing this, Ishihara's spirits lifted.

"The transformation has begun, endure it!"

"Understood!"

Uchiha Tetsuka was clenching his teeth so hard they were about to crack.

It felt as though countless ants were gnawing at his body, causing immense pain and discomfort.

Even his appearance began to age; his hair turned gray, and his skin wrinkled.

Outside the barrier, Fugaku and the others watched this scene, their faces contorted in pain.

"Tetsuka, you must hold on!"

The entire forest fell into a hushed silence.

The only sound was Uchiha Tetsuka's hoarse cries from within the barrier.

Ishihara watched silently, indifferent to Tetsuka's fate, caring only about the success of his experiment.

"It's close, almost there!"

As the mutated organ became more active, Ishihara's focus intensified.

He didn't know how much time had passed, but Uchiha Tetsuka now looked like a man in his sixties.

At that moment—

Buzz—

The critical point was reached!

The special organ mutated!

A surge of unique chakra was born, instantly flooding into Uchiha Tetsuka's eyes.

The three-tomoe Sharingan automatically activated, and under the influence of this unique chakra, its structure began to change.

A new pattern was formed!

"The Mangekyō Sharingan?!"
