What happened to the Uchiha family is really weird.

What is known to the public is that the S-rank rebel Uchiha Itachi slaughtered all of his clan members, including his parents, leaving only his younger brother Uchiha Sasuke alive.

Although most ninjas would find this jaw-dropping thing incredible, they would not delve into it too much, after all, it is none of their business.

For so many years, Uchiha Sasuke has firmly believed in this well-known fact.

But since becoming a jonin, Sasuke has measured through actual experience and personal understanding how difficult it is to wipe out the Uchiha clan quietly and completely with one person's strength.

No matter how you think about it, there's no one in the ninja world who can do this.

This is a huge family with an overall strength equivalent to half of Konoha Village. In addition to Uchiha Fugaku, the clan leader and father of Uchiha Sasuke and Uchiha Itachi, there are also a large number of elite jonin who can compete for the position of Hokage.

With the strength of the Uchiha Clan, it was enough to launch a small-scale Ninja World War, but incredibly, they were killed silently in the strongest ninja village in the Ninja World. This is too incomprehensible.

Uchiha Sasuke regained his spirit and looked up at Uchiha Itachi who had an expressionless face.

"Really? Although I still have many questions, since you have admitted it, then killing you will not be a mistake."

The power of the curse seal was activated again. It was unknown how many times it had been used today. Even Uchiha Sasuke himself had become somewhat numb to the danger of this power.

Especially now that Orochimaru has been defeated by him, he has no worries and will not be reluctant to use this secret technique that can greatly enhance his strength in a short period of time.

The illusion duel just now was roughly a draw, and neither side was able to gain an absolute advantage. In comparison, Uchiha Itachi had a slight advantage.

But Tsukuyomi itself is a unique eye technique of the Mangekyō Sharingan, which consumes a lot of eye power and puts a lot of pressure on one's own chakra to support it.

Uchiha Sasuke was at a disadvantage in terms of skills, but in terms of absolute spiritual power, he was not inferior to Uchiha Itachi.

It was normal for the two of them to fight so well since Uchiha Itachi didn't force them too much.

"So, in the end, you still have to rely on the power given by others? The only thing that can make you improve is the Sharingan, but you still don't have it. It seems that your hatred is just like this. I overestimate you."

"How can there be good or bad strength? As long as it can kill you, it's enough."

"Really? Let me see it for myself."

Uchiha Sasuke was fully prepared and said no more words. His best lightning technique was not restrained by the enemy.

It’s not that Uchiha Itachi doesn’t know wind jutsu, but if he must use it, it would be more reliable to use his best fire jutsu and illusion.

Although he had overestimated Uchiha Sasuke's strength, Uchiha Itachi still underestimated Uchiha Sasuke's talent.

As expected, Uchiha Sasuke was obviously faster than Uchiha Itachi.

In a ninja duel, it is not enough to just be fast and flexible.

Having an advantage in speed makes it easier to take the initiative, but having an advantage on the field does not mean that you can really win.

Every time Sasuke tried to attack in the blind spot of Uchiha Itachi's sight, after suppressing his opponent for a while, he still failed to inflict effective damage to his opponent.

"You've gotten stronger, Sasuke!"

Taking advantage of the brief pause, Uchiha Itachi wiped off the bloodstains on his body.

Sasuke, who had the advantage, undoubtedly consumed far more physical strength and chakra than Uchiha Itachi.

Although his speed is not as fast as Sasuke, Uchiha Itachi's fighting talent is fully demonstrated at this time.

Relying on his agile body, he twisted and turned, and used extremely small defensive movements to barely block Sasuke's attacks, just barely coping with the violent storm of attacks.

"Really? There are even more powerful ones coming next."

Uchiha Sasuke bit his right index finger, formed seals with both hands, summoned the ninja tool, and a shining long sword appeared in the palm of his hand.

"Kusanagi sword?"

Uchiha Itachi frowned.

"It seems that you really have inherited Orochimaru's legacy. However, you are not naive enough to think that you will be more powerful if you have one more sword, right?"

"You don't need to worry about this. As long as the Uchiha clan members who possess the Sharingan see it a few more times and practice diligently, there will be no ninjutsu or taijutsu that they cannot learn!"

Although Sasuke's words were a bit arrogant, the general sense of ninjutsu, taijutsu and even illusion can indeed achieve this. As for the swordsmanship which has no threshold, it is even more of a piece of cake.

"What do you think I've done all these years?"

Ever since he witnessed the swordsmanship expertise of the Kirigakure ninjas, especially Chojuro's two-handed swordsmanship, Uchiha Sasuke has become even more excited. This kind of killing technique is too powerful in battle, and every move is intended to kill people.

Uchiha Sasuke, who was bent on revenge, used his Sharingan to observe very carefully, but it was difficult to find a good sword that could cooperate with his Lightning Release to use the Chidori Blade.

Kakashi Hatake got the materials of the Bloody March Scythe from Mizuki and made a good sword, but the second sword to make the icing on the cake naturally could not trouble Kakashi anymore, after all, he was now a jonin.

Although I have practiced for a long time, I have never been able to put my skills to good use.

Now, Uchiha Sasuke, who has received the Kusanagi sword from Orochimaru, has finally had the opportunity to practice the two-handed swordsmanship he has practiced for a long time.

The red and white swords crossed, and the lightning flowing on the swords became stronger and stronger, constantly making a crackling sound, showing its extraordinary power.

The red sword is more inclined to injure and bleed, but its piercing power depends entirely on the form-changing Lightning Style Chidori, so its ability to break through defense is slightly weaker.

The Kusanagi sword is much sharper than the red sword and has an indestructible property. Theoretically, it can cut through all physical objects. However, it is less effective when facing invisible barriers such as energy and chakra. That is why it cannot penetrate the tailed beast coat of Uzumaki Naruto in the four-tailed state.

But this is all relative. With the help of the more excellent Kusanagi sword, Uchiha Sasuke's lethality has increased by more than one level.

Sasuke, with a long shadow, began to change his fighting style. Although he was not as fast as before, his every move was so sophisticated that it was more difficult to resist.

The two Chidori blades, combined with the storm of thunder and fire caused by the lightning sword wings, suppressed Uchiha Itachi to the point where he had almost no power to fight back. The myth of fighting against swords with bare hands is not what a ninja should do.

Although Uchiha Itachi, who was trying his best to cope with the situation, had not been seriously injured, the wounds on his body were increasing. His originally flowing divine robe had been cut in several places, and several places were burned black by lightning...
