Naruto: Forced to activate Infinite Tsukuyomi in order to return home

"What method?"

Shisui couldn't help but ask a question. In his opinion, he didn't really care about improving his strength.

However, Fengtian's eyes were deep. He stared intently at Zhishui, pondered for a moment, and finally decided to speak:

"Your strength can't be increased as directly as theirs..."

"The only way to achieve a significant improvement is to start with your Mangekyou Sharingan..."

"The Mangekyou Sharingan?"

Zhi Shui continued to ask, his brows furrowing slightly, as if he didn't quite understand Feng Tian's thoughts.

"right!"

"If you could evolve your Mangekyou Sharingan into the Eternal Mangekyou Sharingan, your strength would experience a qualitative leap!"

"Even the Susanoo might evolve into the Perfect Susanoo!"

Upon hearing this, Shisui's pupils contracted sharply, clearly deeply shocked by Fengtian's words.

The Eternal Mangekyou Sharingan is a realm that countless Uchiha clan members dream of. It not only prevents vision loss caused by using the Mangekyou Sharingan, but also unlocks even more powerful abilities.

The Complete Susanoo is a legendary being, possessing world-destroying power.

"However... to do this, I would need to transplant my brother's Mangekyou Sharingan..."

Shizuku's voice trembled slightly; he knew all too well what this meant.

Within the Uchiha clan, there are countless examples of brothers killing each other for power. Is he truly willing to bear such a price?

Fengtian seemed to see through Zhishui's hesitation. He gently patted Zhishui's shoulder and said confidently:

"You don't need to worry about that. With my [Power of Cause and Effect], I can skip this step and directly evolve your [Mangekyou Sharingan] into the [Eternal Mangekyou Sharingan]..."

"only…."

"Just what?"

Shisui pressed on, and upon hearing the words "Eternal Mangekyou Sharingan," even he, usually so calm, lost his composure.

"However, this method comes at a high cost; what I need to do is mortgage your future..."

Having said that, Fengtian stared sharply at Zhishui in front of him, anticipating his reply.

Fengtian's method is simple: to extract the power of Zhishui from the future timeline in advance, using the power of cause and effect as a link.

Doing this would have little backlash against Fengtian, but it would ruin Zhishui's future path!

After all, someone like him who overdraws his power in advance will have his causal lines completely disrupted. Even Fengtian, who controls the power of causality, doesn't know what Shisui will be like in the future.

"Have you made up your mind?"

Fengtian spoke again and asked a question.

Upon hearing this, Zhi Shui's body trembled slightly, and his gaze lingered on Feng Tian's face for a long time, as if he were weighing the pros and cons of this decision.

His heart was like a turbulent ocean, with waves surging and crashing.

On one hand, the allure of the Eternal Mangekyou Sharingan was simply too great; it meant unprecedented power, enough to protect everything he cherished.

On the other hand, the cost of overdrawing the future is equally heavy; he may lose unknown possibilities and room for growth as a result.

"Fengtian... are you giving me a choice?"

Zhi Shui's voice was deep and complex. He slowly raised his head and looked directly into Feng Tian's eyes, trying to find the answer in the other's gaze.

Fengtian did not avoid Zhishui's gaze. He nodded, his tone firm:

"Yes, Shisui, this is your choice..."

"Whichever path you choose, I will respect your decision..."

"But you must understand that once a choice is made, there is no going back."

Shisui fell silent. He closed his eyes, countless images flashing through his mind, before slowly saying:

"I'm tired of this war filled with gunpowder smoke..."

"The conflicts between great powers are tearing countless families apart; this is not the world I want..."

"Fengtian, what does it matter if I gamble my future for the [Eye of the Moon] project?"

Shisui's words revealed a sense of determination and sacrifice, and his eyes shone with a longing for peace and a deep weariness of the current chaotic world.

He seems to have made a decision, willing to bear the heavy price of mortgaging the future for a greater goal—ending the war and achieving peace.

Looking into Zhishui's resolute eyes, Fengtian felt a complex mix of emotions welling up inside him.

He admired the determination to stop the flooding, but was also worried about the potential consequences of the decision.

He knew that once Shisui embarked on this path, there would be no turning back, and his future would be completely rewritten.

"Zhishui, are you really sure? This path won't be easy. You might lose a lot, including your future growth and possibilities."

Fengtian reminded him again, hoping that Zhishui would think carefully and not make a decision he would regret.

Zhi Shui smiled slightly, his eyes filled with determination and relief:

"Fengtian, I've made up my mind..."

In this world filled with war and conflict, individual growth and future seem so insignificant…

"If my sacrifice can bring about world peace, then I am willing to take on this responsibility."

Upon hearing this, Fengtian sighed deeply. He knew that Zhishui had made his decision, and no amount of persuasion could change his mind.

So he nodded and decided to respect Shisui's choice.

"Alright, Shisui."

"Since you've made up your mind, I will do everything I can to help you achieve this goal."

"But you must remember, whatever the future holds, this is your own choice."

Fengtian said in a heavy tone.

"Come forth, Fengtian!"

This time, Shisui spoke without the slightest hesitation; he had made up his mind.

Seeing this, Fengtian did not hesitate any longer. He manipulated the [Power of Cause and Effect] and headed towards Zhishui.

The next moment, thin lines of cause and effect appeared on Shisui's body.

That is the causal line connecting still water to the river of time.

Fengtian carefully manipulated these "causal lines," using them to find the timeline of the period when Zhishui was at its most powerful.

As Fengtian meticulously manipulated the causal threads on Zhishui's body, the entire space seemed to freeze, and time lost its original smooth rhythm at this moment.

Shisui could feel a strange power surging within him, a power belonging to the future, being drawn here in an incredible way.

"Found it."

Fengtian whispered, his fingers gently touching a causal line that radiated a dazzling light—a mark of a future peak moment for Zhishui.

At this moment, Fengtian's eyes became exceptionally bright, as if they could see through all illusions and directly perceive the essence of cause and effect.

Shisui closed his eyes with a mixture of tension and anticipation, feeling a warm and powerful force slowly flowing into his body.

That was a level of power he had never experienced before, as if the mysteries of the entire universe were being revealed to him at that moment.

"Hold it, Shisui!"

Fengtian reminded him, a hint of worry in his voice.

Guided by Fengtian, Shisui's Mangekyou Sharingan began to tremble violently, as if some ancient and powerful seal was about to be broken.

An indescribable pain instantly swept through his body. Shisui gritted his teeth, and veins bulged on his forehead, but there was no sign of retreat in his eyes.

"ah--"

Shisui let out a low roar, a release of pain and a thirst for power.

At that very moment, Shisui's Mangekyou Sharingan suddenly burst forth with dazzling light, and the pattern underwent a dramatic change!

The original complex patterns have been replaced by deeper, purer designs!

The Eternal Mangekyou Sharingan has finally awakened at this moment!
