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

"How could this be..."

Upon hearing Fengtian's words, Obito's face immediately showed an embarrassed expression.

He muttered to himself:

What a joke! All you know is Wood Release and that Kamui that's like you've got a cheat code, right?

That's not strong at all! It's incredibly weak!

He looked around, his gaze settling on the three Uchiha clan members present.

Besides himself, Madara, Shisui, and Fengtian were all able to use the [Complete Susanoo]!

I want to pilot such a powerful "Gundam" myself, don't I?

Sensing that Obito's eyes were gradually dimming, Fengtian chuckled inwardly and decided to stop teasing him.

He slowly walked to the wooden chair, sat down gracefully, crossed his legs, and adopted a leisurely posture, saying slowly:

"Actually..."

"There are still ways to improve..."

"My shoulders have been a bit sore lately, though. It would feel so much better if someone could give me a massage..."

Upon hearing this, Obito's eyes lit up instantly, like a drowning person suddenly grabbing a piece of driftwood.

He quickly stood up, took a few steps behind Fengtian, gently placed his hands on Fengtian's shoulders, and carefully began to massage him, asking tentatively as he kneaded:

"Lord Fengtian, is the method of improvement you mentioned true? Could you... tell me in detail?"

Fengtian hummed comfortably, a pleasant smile playing on his lips, clearly enjoying Obito's massage.

He said slowly:

"Of course, since you're quite clever, I'll reluctantly lend you a hand..."

After speaking, Fengtian got up from his seat, stretched his muscles and limbs, and continued:

"Actually, the best way for our Uchiha clan to increase our strength is to awaken the legendary 'Third Power,' which is the 'Susanoo'!"

"However, to awaken such an incredible ability, the prerequisite is to have a complete pair of Mangekyou Sharingan..."

"As far as I know, Obito..."

Fengtian abruptly changed the subject, looking intently at Obito:

"Your other eye is now in Kakashi's hands..."

"Therefore, you are currently unable to use [Susanoo]..."

"but……"

Fengtian deliberately kept everyone in suspense, a hint of mystery flashing in his eyes.

"But what?"

Obito asked anxiously, his eyes filled with longing.

"I can use the power of causality to alter reality for you, creating a fake eye, and Kakashi's Sharingan won't be affected by it..."

"However, this [Hypothetical Eye] can only be used to assist you in using [Susanoo], and cannot be used for any other abilities..."

Obito's heart suddenly raced, as if he heard the turning point of his destiny being revealed. His voice trembled with excitement:

"Lord Fengtian, are you... are you serious? I can possess the complete Mangekyou Sharingan and even use Susanoo?"

Fengtian smiled slightly, a profound glint in his eyes:

"That's right, but it doesn't come without a price..."

"Using the power of causality to alter reality requires a tremendous amount of energy and mental strength, and such changes will place a certain burden on your soul..."

"You must be prepared to bear the consequences of this power."

Obito nodded without hesitation:

"I'm willing! Whatever the cost, as long as it creates a world with Rin, the consequences are insignificant to me!"

Looking at Obito's determined eyes, Fengtian sighed softly and then stopped hesitating.

"Are you ready? Once you start, there's no turning back."

Fengtian's voice was deep and solemn.

Obito took a deep breath, nodded, and his eyes were filled with determination.

In the next instant, the vast and boundless [power of cause and effect] surged towards Obito's right eye like a raging torrent.

Obito felt a warm and powerful force surge into his right eye, instantly spreading throughout his entire body, as if every cell was being nourished by this power.

Immediately afterwards, he felt an indescribable pain in his right eye, as if something was tearing his eyeball apart, and then it was rapidly reassembled and repaired at an incredible speed.

As the blinding light gradually dissipated, Obito slowly opened his eyes.

At this moment, his right eye had undergone a dramatic transformation. A pair of brand-new Mangekyou Sharingan shone brightly on his face, radiating an eerie light that sent chills down one's spine, as if it could see through all the secrets of the world.

He raised his hand and gently touched those eyes, feeling an unprecedented power surging within him.

"This is..."

"To gather the power of both Mangekyou Sharingan?"

Obito muttered to himself, his tone a mixture of shock and anticipation.

Fengtian walked up to Obito and patted him on the shoulder:

"Go, try to summon your Susanoo..."

Immediately afterwards, with a spatial shift, Obito and Fengtian arrived in the [subspace].

Obito took a deep breath and tried to mobilize the newfound power within his body.

He slowly raised his hands, interlocked his fingers, and closed his eyes to concentrate.

Suddenly, a powerful surge of chakra erupted from his body, causing the space itself to tremble.

Obito's eyes shone with an intense light, a unique brilliance of the Mangekyou Sharingan, containing endless mysteries and power.

"Susanoo!"

With Obito's low growl, an indescribable pressure enveloped the entire [subspace].

A gigantic phantom of a war god slowly coalesced behind him; it was the legendary [Perfect Susanoo] of the Uchiha clan.

It was clad in blue armor, had wings on its back, and its eyes were like burning flames, radiating a suffocating sense of oppression.

Obito stared in awe at the war god summoned by his own will, his heart surging with unprecedented excitement and pride.

He felt an unprecedented power, as if the whole world was trembling beneath his feet.

"Is this... my Susanoo?"

Obito's voice echoed in the vast [subspace], carrying a hint of disbelief and boundless joy.

Fengtian stood aside, watching all this with a smile, a hint of admiration flashing in his eyes.

He knew that at this moment, Obito was no longer the boy who only relied on Kamui to escape reality, but a Uchiha warrior who had truly embarked on the path of the strong.

But Obito's joy was like a dazzling firework, fleeting in an instant.

Like Shisui, his physical strength quickly reached its limit, and his [Complete Susanoo] slowly collapsed and dissipated like a sandcastle blown away by the wind.

This time, Fengtian was well-prepared. He steadily caught the swaying Obito and gently repaired Obito's exhausted body using the miraculous technique of "reversing cause and effect".

Once it was confirmed that Obito was out of danger, Fengtian snapped his fingers lightly, and the space seemed to be gently twisted, causing the two figures to disappear instantly.

When they reappeared, they were already deep underground. The two of them then returned to the underground.

"Fengtian! Thank you so much! This power is simply beyond imagination!"

Obito excitedly grasped Fengtian's hand, his eyes shining with gratitude, and secretly vowed to do his best to master this power in this limited time.

Fengtian smiled gently, a hint of mystery in his eyes, and slowly spoke:

"Besides the [Complete Susanoo], you actually have room for further improvement..."

"Oh? There's still room for improvement?"

Obito raised an eyebrow, a look of curiosity on his face.

Fengtian nodded slightly, paused briefly as if considering his words, and then slowly said:

"You can try to think about how to subtly integrate this power of Kamui into your own ninjutsu..."
