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

"This is the sixth time, isn't it..."

"Damn it, can't you remember anymore?"

Deep underground, a young man named Uchiha Fengtian rubbed his groggy head and muttered to himself as he got up.

His true identity is that of a time traveler!

By chance, he was transported to the world of Naruto. According to the system's prompts, he needed to help Madara Uchiha complete the "Eye of the Moon" plan.

Unfortunately, each attempt was thwarted by Naruto Uzumaki, preventing the "Eye of the Moon" plan from proceeding smoothly.

Fortunately, the system has nine chances to recover from failure. If it fails, it will rewind time and start over.

However, the timing and location of this regression are both random...

"Distance from completing Project Eye of the Moon --- 0/9"

When Fengtian awoke, this text popped into his mind.

Fengtian read the text expressionlessly, his heart unmoved.

Having gone through six cycles, he knew very well what 0/9 represented.

This number increases every time a tailed beast is captured and swallowed into the Gedo Mazo.

Each time one is completed, Fengtian's abilities will be greatly enhanced!

But now is not the time to think about that...

"Could this be the place where Madara lived after the final battle?"

Fengtian looked around repeatedly, and the scene before him matched the one described in the anime.

"It seems that finding Madara is the most urgent task. In this reincarnation, I must realize the [Eye of the Moon] plan!"

Fengtian muttered to himself, then his pupils suddenly shifted, and his three-tomoe Sharingan instantly appeared.

"While its effect isn't as good as the Byakugan, it can still pinpoint Madara's approximate location based on the flow of chakra!"

After saying that, Fengtian began searching for Uchiha Madara's whereabouts, and there were not too many setbacks along the way.

In just half an hour, he arrived in front of a giant wall that had just been broken through.

Clearly, based on the plot, this should be because Obito had just broken through and went to rescue Rin and Kakashi...

Without much thought, Fengtian looked closely and saw a wooden throne not far away. The old and frail Uchiha Madara, with several tubes connected to the Gedo Mazo, sat on the throne with his hand on his scythe, looking at him warily!

"Who are you? How did you find this place?"

Although Madara Uchiha's voice was soft, it seemed to be filled with an endless sense of oppression.

As he finished speaking, numerous white Zetsu suddenly appeared all around, staring intently at Fengtian as if they would devour him at any moment.

"My name is Uchiha Fengtian..."

"I've come specifically to assist Lord Uchiha Madara in realizing the [Eye of the Moon] plan..."

Upon hearing this, a glint of light flashed in Madara Uchiha's previously deathly eyes. He slowly raised his head to look at Fengtian, and continued speaking in a hoarse voice:

"How did you know about the 'Eye of the Moon' project, you brat?"

"This is a secret, Lord Madara. Please allow me to join the [Eye of the Moon] project..."

Madara Uchiha remained silent. In his view, this plan had been in the works for a long time, and it couldn't be disrupted by the sudden appearance of just one person...

Seeing that Madara remained silent for a long time, Fengtian revealed his three-tomoe Sharingan to Madara, demonstrating his identity and strength.

However, Ban remained silent, his gaze towards Fengtian gradually deepening...

For the Uchiha clan, known for its many geniuses, the three-tomoe Sharingan is nothing special.

Seeing this, Fengtian sighed deeply. Then, after the three-tomoe Sharingan rotated continuously, it actually transformed into the legendary Mangekyou Sharingan!

"[Reversing cause and effect]..."

Fengtian muttered to himself, and a strange power surged toward Uchiha Madara. Seeing this, the many White Zetsu nearby tried to rush forward to stop Fengtian!

"Wait!"

Madara Uchiha roared, stopping the White Zetsu's actions.

Immediately after Madara Uchiha sensed this strange energy, his aged body regained some vitality, and he began to gradually become younger, with abundant chakra distributed throughout his body!

"The Mangekyou Sharingan—as an Uchiha, I naturally understand the price I must pay to obtain this power!"

At this point, Madara Uchiha was no longer old, and he began to try to move his body, wanting to feel it more carefully.

"However, what surprises me is that your Mangekyou Sharingan seems quite special; there's no information about this eye in any records..."

"Lord Madara, I will name these Mangekyou Sharingan 'Destiny'..."

"Lord Madara must have already sensed this strange power. This technique is called 'Reversing Cause and Effect,' which can influence past 'effects' by modifying some of the 'causes' that occurred in reality..."

"In other words, I used these Eyes of Destiny to modify the cause of Lord Madara's aging in the past, thus achieving the effect of regaining his power now..."

After saying this, Fengtian felt discomfort in his eyes. There was no way around it; maintaining Uchiha Madara's powerful "effect" required far too much "cause."

"That's enough, I understand..."

As Madara Uchiha finished speaking, Fengtian breathed a sigh of relief. He quickly deactivated his Mangekyou Sharingan and gasped for breath.

Soon, Madara Uchiha, who had regained his youthful appearance, began to age rapidly again, eventually reverting to his decrepit state...

Age Spot remained seated on the wooden seat. During the brief moment he regained his strength, his thoughts instantly returned to his battle with Hashirama when he was young.

How exhilarating that was! It's just a pity that they should have been comrades-in-arms, but due to their differing ideals, they ultimately went their separate ways...

At this moment, Madara Uchiha stared straight at Uchiha Fengtian in front of him, and nodded slightly to the latter, indicating his affirmation of his strength.

Unlike Obito, his eyes showed more of an affirmation of Fengtian!

"I, Uchiha Madara, am willing to give you this opportunity! Tell me, what do you want to do?"

Madara Uchiha slightly raised his head and looked at Fengtian with a scrutinizing gaze.

"First, we must eliminate some uncertainties..."

At this point, a hint of killing intent flashed in Fengtian's eyes, which surprised Uchiha Madara who was standing to the side.

"Uncertain factors? What do you mean?"

Madara Uchiha couldn't help but ask, because in his view, there were no uncertainties on his side at all.

However, Fengtian activated his Mangekyou Sharingan once more, assuming a fighting stance. He looked at Uchiha Madara and spoke calmly:

"How long do you plan to hide, Black Zetsu...?"

"Or perhaps, Kaguya Otsutsuki's third child..."
