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

As Madara Uchiha's words fell like ice, the black hole's suction suddenly increased countless times, as if the power of the entire universe had gathered here at this moment, ready to devour everything.

Fengtian's face remained expressionless. He gave up resisting, letting his body, like a light feather, be drawn by the endless darkness and slowly fall towards the center of the black hole.

"Gather!"

Madara Uchiha roared, and with his call, the fragments of the [Heavenly Obstruction Star] seemed to be drawn by an invisible force, rapidly converging towards the black hole.

Immediately afterwards, the gravity at the center of the black hole quickly reached its peak, and the fragments of rock gradually merged as they spun at high speed, forming a huge sphere that emitted a ghostly light.

That's the final form of [Super Planetary Devastation]!

A cage powerful enough to seal away a god!

The figure of "Fengtian" finally disappeared into the depths of the black hole, replaced by a muffled roar, as if something was struggling in despair, but ultimately could not escape the shackles of fate.

"Is it over...?"

Madara Uchiha was panting heavily, his chest heaving violently, and his face as pale as paper.

After using so many high-intensity ninjutsu in succession, even he felt that his body had almost reached its limit, as if every muscle and every bone was protesting.

However, in that brief moment of respite, Madara Uchiha's eyes suddenly narrowed, and an ominous premonition welled up in his heart.

"wrong!"

He murmured softly, his voice filled with fear and unease.

He suddenly realized that his body had not fully recovered!

In the previous battle with "Fengtian", his [Six Paths Power] was sealed by the opponent's [Causal Power], and he has not yet recovered.

This means that all his previous efforts may have been in vain!

"Fengtian was not sealed at all!"

The thought flashed through Madara Uchiha's mind like a bolt of lightning piercing the darkness.

"Have we been discovered?"

"How boring..."

"I originally thought I could see more of your smug expression..."

A leisurely voice, tinged with a hint of regret, rang in Madara Uchiha's ears.

He suddenly raised his head and looked up in the direction the sound came from. He saw "Fengtian" standing with his arms crossed, looking at him with a mocking expression, as if everything that had just happened was just a play he had directed.

Madara Uchiha's face showed an expression of disbelief, his eyes wide open and his lips trembling slightly.

"How is that possible!"

"How did you escape the seal of [Super Planetary Devastation]?!"

The "Fengtian" that he saw appeared before him like a ghost, completely unharmed, which completely overturned his understanding.

"Fengtian" smiled slightly, a smile that contained endless depth and mockery:

"That move, I must say, did pose a slight threat to me..."

"But that only applies to my [Causal Avatar]..."

Madara Uchiha's pupils contracted sharply at that moment, as if he had witnessed the most unbelievable thing in the world.

He suddenly realized that what he had painstakingly sealed away was actually just a causal clone of "Fengtian"!

This realization struck him like a bolt from the blue, plunging him into deep shock and despair.

The true "Fengtian" never stepped into that seemingly inescapable seal from beginning to end.

He had been observing from the shadows, toying with Madara Uchiha like a cat playing with a mouse, until he was confident of victory before leisurely revealing himself.

"[Causal Doppelganger]..."

Madara Uchiha murmured softly; the word was both strange and familiar to him.

He understood that this was a unique ability of "Fengtian," a means of creating an avatar almost identical to one's own body using the power of cause and effect, in order to confuse the enemy or carry out specific missions.

"I see... You never used your true form to fight me from the beginning."

Madara Uchiha's tone was filled with bitterness. He realized that he had once again been manipulated by "Fengtian" in this battle.

"Fengtian" nodded slightly, his mockery deepening.

"That's right, Uchiha Madara, you're always too confident, thinking you can control everything with your own power."

"But you've forgotten that there is a power in this world that you can never understand or control—that is the power of cause and effect."

"And I am the god who controls cause and effect in this world!"

As the words "Fengtian" fell, the surrounding air seemed to freeze, and an indescribable sense of oppression enveloped Uchiha Madara's heart.

He knew that the gap between himself and "Fengtian" could no longer be bridged by mere ninjutsu and strength.

"Is there anything else you'd like to say?"

"As the strongest being in this world, I grant you this opportunity..."

The words "Fengtian" fell coldly.

Madara Uchiha gritted his teeth, his eyes burning with resentment.

Despite being utterly exhausted and filled with despair, he refused to give in.

"The strongest?"

Madara Uchiha gave a cold laugh, his voice trembling slightly—a tremor he desperately tried to maintain his dignity.

"Hmph, you're nothing but a coward hiding behind the power of cause and effect!"

Fengtian's expression changed slightly, but he quickly regained his composure.

He seemed to have gotten used to other people's provocations and insults, which were nothing more than insignificant noise to him.

"Say what you will, Uchiha Madara."

Fengtian waved his hand lightly, the gesture carrying an undeniable arrogance, as if he were dispelling the insignificant things before him.

Your words mean nothing to me…

"Now, it's time to end this tedious battle."

Fengtian's voice was cold and resolute. He slowly raised his hand, palm facing up, as if summoning some unknown power.

As he moved, the surrounding air began to fluctuate violently, as if an invisible force was brewing within it, causing the entire space to tremble.

Madara Uchiha could clearly feel an unprecedented sense of crisis rapidly approaching; his heart was racing and his breathing was becoming rapid.

He tried his best to dodge the impending fatal blow, but his body was as if bound by invisible chains, unable to move.

"The chain of cause and effect, the bondage!"

With a low shout of "Fengtian," invisible chains emerged from the void and quickly wrapped around Uchiha Madara's body.

These chains seemed to be woven from the power of cause and effect, and no matter how much Madara Uchiha struggled, he could not break free.

"It's over, Uchiha Madara."

"Fengtian's" tone was full of indifference and mockery. With a wave of his hand, the [causal chains] began to tighten, squeezing Madara Uchiha's body until it was almost deformed.

However, at this critical moment, a bright green spiral spear suddenly pierced through the void, carrying an extremely sharp aura, pointing directly at "Fengtian"!

Fengtian's expression finally changed; he hadn't expected such a powerful counterattack in this desperate situation. He retreated rapidly, barely managing to evade the sudden attack thanks to his astonishing speed and reflexes.

Even so, the powerful chakra fluctuations associated with the Spiral Spear still made him feel a chill; it was a power that could threaten his life.

The next moment, the spiral gun exploded in the void, turning into specks of green light and disappearing into nothingness.

But the sheer power of that instant was enough to make the surrounding air tremble, as if even spacetime was distorted by this force.

Taking this opportunity, Madara Uchiha unleashed the remaining chakra within his body, as if he had found a final desperate struggle for his life.

Using this power, he forcefully broke free of some of the causal chains that "Fengtian" had placed on him, and retreated rapidly, widening the distance between himself and "Fengtian".

"Who?!"
