Naruto: I wrote in my diary that I exposed the Otsutsuki's arrival.

Chapter 15, 55 Open: What? Only one second has passed?

Even Kakashi Hatake himself closed his ordinary eye, leaving only his Sharingan open.

"Never open your eyes. If you see his eyes now, you're done for. Probably only someone with the Sharingan can fight him," Kakashi Hatake said cautiously, though he himself wasn't entirely convinced of his own judgment.

In response, Itachi Uchiha simply said, "With the Sharingan, you can indeed resist my Mangekyou Sharingan to some extent, but you cannot break through the unique eye techniques, genjutsu, and Tsukuyomi of this Sharingan."

"The only one who can defeat me is a Sharingan user who shares the same bloodline limit as me."

In that instant, Kakashi Hatake remembered the only remaining member of the Uchiha clan, Sasuke Uchiha.

"Me?" Sasuke Uchiha said in disbelief off-screen.

He knew the extent of the gap in strength between himself and Itachi Uchiha, and that there was currently no hope for him. However, he still had hope, as he was the only remaining member of the Uchiha clan.

No, there's one more, that Kitahara Kaede.

Sasuke Uchiha instantly thought of another member of the Uchiha clan who was likely a descendant who had been separated from the clan. This person was probably the closest to him in terms of bloodline, besides Itachi Uchiha.

However, he did not know that although Kitahara Kaede had the blood of the Uchiha clan, he was not a member of the Uchiha clan.

In the scene, Kakashi Hatake only called out "Sasuke" and felt himself being pulled into a black and white mental world.

He found himself bound to a cross, and opposite him, Itachi Uchiha was staring intently at him with a long sword in hand.

"Without a bloodline limit, how long can you last?"

With that, he plunged a knife into Kakashi Hatake's body, and Kakashi Hatake immediately fainted. When he woke up again, he found himself unharmed on the cross.

He thought he had just encountered an illusion, and that it was just a delusion.

Uchiha Itachi, who was opposite him, attacked again without any mercy, stabbing him in once more.

"In the world of the moon, space, time, and even mass are all under my control. In the next seventy-two hours, I will attack with my knife, one strike after another."

After being tortured for an unknown amount of time, Kakashi Hatake opened his eyes to find himself once again conscious and bound to a cross.

"In the world of the moon, space, time, and even mass are all under my control. In the next seventy-two hours, I will attack with my knife, one strike after another."

Itachi Uchiha repeated it again, driving Kakashi Hatake to the brink of collapse.

"Calm down, this is just an illusion."

It must be said that Kakashi Hatake is indeed a seasoned and experienced Jonin, but he misjudged this time. Itachi Uchiha's genjutsu was no ordinary genjutsu.

"Don't think you can ignore it just because it's an illusion. This pain is not an illusion. This kind of suffering is no different from reality. How long can your spirit hold on?" Uchiha Itachi stabbed in again without any mercy.

Even more terrifying, under the illumination of the blood moon in the sky, countless Kakashi Hatake appeared in the Tsukuyomi space, and then countless Itachi Uchiha appeared in the same Tsukuyomi space.

"71 hours, 59 minutes, and 59 seconds remain," Itachi Uchiha said coldly.

"Only... only a second has passed?" Kakashi Hatake was pierced by the countless longswords.

The horrific torture was so intense that even Kakashi Hatake and Sasuke Uchiha, who were off-screen, were terrified.

"This Tsukuyomi, this genjutsu..." Kakashi Hatake was shocked. This Tsukuyomi was too unfair.

He used to work with Itachi Uchiha, when Itachi was just one of his subordinates. Even then, he knew that Itachi's genjutsu skills were quite extraordinary.

But I never expected it to be this strong.

Among his colleagues, Kurenai Yuhi was also a Jonin known for her genjutsu, and her family was a genjutsu family. However, in the face of Itachi Uchiha's genjutsu, she was like a child.

This is no longer an ordinary illusion; is it the Mangekyou Sharingan's enhancement of illusions?

Information about the Mangekyou Sharingan flashed through his mind. Given his status and the Hatake clan's accumulated knowledge, he knew a little about the Uchiha clan. He knew that in addition to the regular three-tomoe Sharingan, the Uchiha clan also had a Sharingan called the Mangekyou Sharingan, which was said to be quite extraordinary.

However, he didn't know much more, especially since the Uchiha clan was later wiped out, which made the research even less possible.

He never expected that the Mangekyou Sharingan of the Uchiha clan could be so powerful.

He also possessed the Sharingan, even if it was an external Sharingan, but it couldn't be faked after all, and in an instant he was pulled into the genjutsu space by the other party.

The resistance to ordinary illusions that he was usually so proud of was useless at this moment.

Sasuke Uchiha was even more shocked. He had witnessed the brutal torture Kakashi Hatake suffered in the scene just now, but it had been so long. Itachi Uchiha said that only a second had passed.

And then came another 72 hours of torture.

If it were him, he would probably collapse instantly.

Is this Itachi Uchiha's current strength?

Is it really that terrifying?

He suddenly remembered what Kitahara Kaede had written in his diary: there are differences between Sharingan.

This seems to be talking about the difference in Sharingan between Kakashi Hatake and Itachi Uchiha, but isn't it also talking about the difference between myself and Itachi Uchiha?

Do you have to have the same eyes as him to have any chance of matching him?

Is there any connection between Itachi Uchiha's strength and his eyes?

At this moment, Sasuke Uchiha recalled a discussion he had overheard among his clansmen when he was a child. He remembered how the Sharingan, when awakened or evolved, brought about a significant increase in strength.

This is why the Uchiha clan, despite being a prestigious family with ocular jutsu and bloodline limits, is often considered more powerful.

While it can't compare to the Hyuga clan's practice of endogamy to maintain bloodline purity, which resulted in every Hyuga member being able to awaken the Byakugan, the Sharingan is far more difficult to awaken, making every Uchiha clan member who can awaken the Sharingan an elite among elites.

"Does it really take those eyes to be better than you? Uchiha Itachi, I'll show you no way! Even without those eyes, I'll still kill you to avenge my entire clan!"

"Uchiha Sasuke muttered to himself."
