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

Faced with Fengtian's sudden appearance, Shisui and Itachi quickly adjusted their mindset and entered a state of battle preparation.

They knew that whatever the purpose of their trip to Fengtian, they had to remain vigilant to deal with any possible situation.

Shisui narrowed his eyes slightly, looking Fengtian up and down, trying to glean more information from the other's expression and demeanor.

Meanwhile, Itachi silently activated his Sharingan, preparing to capture Fengtian's movements at any time in order to prepare for any possible battle.

"Who are you? What do you want with us?"

Zhi Shui asked calmly, his voice revealing an undeniable authority.

Fengtian smiled slightly but did not answer immediately.

He seemed to be enjoying the tense and subtle atmosphere, as if he was waiting for something.

Finally, he slowly spoke:

"My name is Uchiha Fengtian..."

"We came here for the future of the Uchiha clan."

Upon hearing this, both Shisui and Itachi couldn't help but show expressions of surprise.

They never expected that Fengtian would so directly mention the future of the Uchiha clan.

"What do you mean?"

Uchiha Shisui narrowed his eyes, his hand gripping the hilt of his sword tightly, ready to strike at any moment.

"My goal is to create a world without strife, war, or killing..."

"So, Uchiha Shisui, Uchiha Itachi..."

"I need your help..."

Fengtian spoke in a low voice, which, though soft, still reached the ears of the two men accurately.

Upon hearing this, a strange expression flashed across Shisui's face, but it quickly disappeared.

"What reason do I have to believe you, and how can you prove yourself?"

As soon as Zhi Shui uttered those words, the atmosphere in the entire room instantly plummeted to freezing point.

Feng Tian sighed softly, then activated his Mangekyou Sharingan. His purpose was clear: if they were not convinced, he would beat them until they were!

Shisui moved very quickly, appearing behind Fengtian almost the instant he activated his Mangekyou Sharingan.

Without much hesitation, he swung his sword and struck.

However, just as the short sword was about to make contact with Fengtian, Fengtian's figure vanished from the spot.

The next moment, Fengtian slowly emerged from the woods, as if nothing had happened.

"A high-level Substitution Jutsu?"

"wrong…."

"It's a space-time ninjutsu!"

Shisui's reaction and analytical abilities were simply terrifying; in just one glance, he guessed the type of ninjutsu Fengtian was using.

He was right. Fengtian had just used the Flying Thunder God Technique to instantly teleport to the location he had marked beforehand, and calmly dodged Shisui's attack!

"Shall we continue?"

Fengtian's face remained calm, as if all of this was perfectly natural.

However, Shisui slowly got up and continued to maintain his fighting stance. At the same time, his three-tomoe Sharingan was activated, ready to observe Fengtian's actions.

There aren't many space-time ninjutsu techniques. As long as he continues to probe a few more times, he will be able to gather information about the opponent and take corresponding measures!

With this in mind, Shisui began to act again, his movements becoming faster and faster. Even Fengtian, who possessed the Mangekyou Sharingan, could only barely catch a glimpse of his afterimage.

"We succeeded!"

A smile flashed across Zhishui's face as he reappeared behind Fengtian. This time, he seized the moment when the other was distracted and unleashed his sword strike.

However, the result was strikingly similar: just before the short sword made contact with Fengtian, his figure vanished from the spot and then slowly emerged from the woods...

"This disappearance is more like a teleportation, somewhat similar to Minato Namikaze's signature Flying Thunder God Technique..."

Through this test, Shisui gained a basic understanding of Fengtian's ninjutsu.

Therefore, to verify his thoughts, Uchiha Shisui turned around, quickly formed hand seals, and soon a [Fire Release: Great Fireball Technique] was launched towards Fengtian!

The enormous fireball, carrying an aura of destruction, relentlessly swept away everything around it!

Fengtian felt a wave of heat rush towards him, and dodged it in the next moment.

It wasn't that he didn't want to use the Flying Thunder God Technique, but rather that Shisui's Fireball was aimed directly at the forest that Fengtian had marked with the Flying Thunder God Technique!

Even if he uses the Flying Thunder God Technique, he still won't escape the Fireball Jutsu attack, so he can only dodge it!

"Just as I expected..."

Shisui looked at Fengtian, who had dodged the Great Fireball, and instead of being discouraged, he smiled smugly.

Everything went exactly as he expected; the space-time ninjutsu used by Fengtian was none other than the Flying Thunder God Technique!

Now, his Fireball has destroyed the marked forest, which means that Fengtian is temporarily unable to use Flying Thunder God Technique to dodge his attacks!

Thinking of this, Shisui's smile grew even wider. His figure vanished from the spot in an instant, and he reappeared behind Fengtian almost the moment Fengtian dodged the fireball and landed!

"This time, let's see how you hide!"

Without much hesitation, Shisui swung his sword directly at Fengtian!

However, when faced with Shisui's attack, Fengtian simply turned around, a meaningful smile appearing on his face!

"[Reversing cause and effect]..."

"【Flying Thunder God Technique - Second Stage】!"

"Whoosh!"

To Shisui's astonishment, Fengtian once again escaped his attack using the Flying Thunder God Technique!

Immediately afterward, before he could even react, a kunai was pressed against his waist…

"The outcome is decided, Shisui..."

Behind him, Fengtian was using a kunai to shield himself, his words still calm and collected, as if it were all part of his plan…

"Impossible! Your mark should be in the woods, how could it appear behind me?"

Shisui turned to look at Fengtian with a puzzled expression on his face.

"It's simple, we'll just leave a mark on you..."

"Impossible, when did you mark me?"

Upon hearing this, Fengtian pointed to his Mangekyou Sharingan and then said:

"This is the power of my Mangekyou Sharingan; it can alter all causes and effects in the world..."

"The cause of the mark you destroyed before has been changed by me into the effect of the mark on you..."

"I understand..."

After saying that, Shisui put down the short sword in his hand, and a look of relief appeared on his face.

This time, he lost completely. However, as a genius of the Uchiha clan, he was naturally able to accept defeat and let it go.

At this moment, Shisui opened his arms and his eyes switched to normal pupils, as if he was ready.

However, before Fengtian could make any move, he felt a kunai pressed against his waist...

"You're too careless. Have you forgotten I exist...?"
