I, the Demon Back Boss of the Uchiha Clan

In the 48th year of Konoha, early February, early morning,

Konoha Ninja Village, at the training ground outside the Uchiha clan.

A 15-year-old black-haired boy was running quickly along the track of the training ground.

Tick-tock!

Tick-tock!

Sweat kept dripping from his face.

The boy looked extremely handsome, but his body was full of angular bronze muscles, hard body lines, and explosive power.

Behind him, there was a faintly visible hideous tattoo, which looked very scary.

"10 kilometers!!"

"5 kilometers!"

"1 km!"

After completing the last three laps and accelerating the sprint, the young man lay on his back on the training ground, sweating profusely, looking at the rising sun behind the Hokage Rock, his eyes becoming a little absent-minded.

"unconsciously……"

"I have been in this world for three years!"

Sweat rolled into his eyes, making his vision a little blurry, but the rising sun behind the Hokage Rock was still dazzling in Uchiha Kazuya's eyes.

Yes, he is a time traveler.

It has been three years since Kazuya came to the world of Naruto.

In fact,

Kazuya is not unfamiliar with the matter of time travel.

But when he learned that he had traveled to the Uchiha clan, his mood was still very complicated.

Because, Kazuya

, who is familiar with the plot of Naruto, knows that traveling to the Uchiha clan means obtaining the strongest bloodline limit in the Naruto world - the Sharingan!

However!

This also means that he has to face the most difficult copy to survive - the Uchiha clan extermination night!

The extermination night!

The massacre of the Uchiha clan by two Mangekyōs who were brainwashed by the Konoha high-ups - Uchiha Shisui and Uchiha Itachi, and the behind-the-scenes boss Uchiha Obito! It makes people's scalp tingle just by listening to it!

Moreover! Kazuya is also the grandson of the great elder of the Uchiha clan, and he has a very high status in the clan.

In other words, if the genocide really happens, he will definitely be one of the first to be stabbed.

The pressure is huge!

Three years.

It also made Kazuya realize that the ninja talent of this body is really average.

The Sharingan is only a single magatama. If it can be opened to three magatama in the future, it will exceed expectations. Mangekyō is something that he dare not even think about.

With this kind of strength, he is just a cannon fodder in the genocide.

"only……"

"As a time traveler, it's not too much for me to have a system, right?"

A smile suddenly appeared on Kazuya's face.

Then

, a brilliant light curtain appeared in front of him.

【Host: Uchiha Kazuya】

【Level: lv1】

【Charm: 100】

【Power: 5.2】

【Speed: 3.6】

【Constitution: 3.9】

【Chakra: 4.5】

【Ghostback completion rate: 11.9%】

【Current ghost back effect: cultivation speed increased by 10 times!】

【Tip: An attribute value of 1 represents a Hatake Kakashi, i.e. a strength of 5.2 represents a strength value 5.2 times that of a Hatake Kakashi.】

【Tip: If the host runs 10 kilometers, does 100 sit-ups, 100 push-ups, and 100 squats every day, he can randomly improve his attributes!】

【After completing the fixed training today, you will gain 0.05 points of strength, 0.03 points of speed, 0.04 points of physique, and 0.05 points of chakra.】

【The current cultivation speed is 10 times!】

【After the amplification, the host can obtain: 0.5 points of strength, 0.3 points of speed, 0.4 points of physique, 0.5 points of chakra】

……

Instantly, a warm energy spread from Kazuya's heart and quickly flowed to every corner of his body.

The next moment, the feeling of physical fatigue also disappeared, and Kazuya felt relaxed and full of energy again.

Bonus!

This is an attribute bonus!

Kazuya was excited.

He took another look at the virtual light screen and found that his attributes had improved a lot.

【Host: Uchiha Kazuya】

【Charm: 100】

【Strength: 5.7】

【Speed: 3.9】

【Constitution: 4.3】

【Chakra: 5.0】

【Ghostback completion rate: 11.9%】

【Current ghost back effect: cultivation speed increased by 10 times!】

【Tip: After the completion of Ghost Back reaches 20%, you will get a 100-fold training speed bonus!】

……

Ten times increase!

The training effect is very good!

It is equivalent to roughly increasing 0.5 Kakashi's attribute value every day!

Very strong!

Hatake Kakashi is a super genius, the direct disciple of the Fourth Hokage, the future Sixth Hokage of Konoha, incredible!

Of course.

Now Kazuya is even stronger, his strength and chakra are more than five times that of Kakashi, and his speed and physique are about four times. If they really fight, he can definitely beat the current Kakashi!

"The completion of the Ghost Back has reached 20%, and the training speed can be increased to 100 times?"He was also very surprised.

100 times!

This means that after completing one training, he can increase his strength by 5 points, five times Kakashi's value!

"hiss……"

Kazuya took a deep breath.

Five Kakashis in one day, this is really amazing!

However, it is very troublesome to improve the completion of this Oni. In addition to relying on daily training, it can only be improved by completing the tasks issued by the system.

However.

The tasks of the system are very rare.

Since awakening the system a year ago, Kazuya has only encountered it twice, but these two times have allowed him to improve the completion of Oni by 6%, which is a very good benefit.

"never mind……"

"The system's tasks can only be done at random, and the current 10 times training speed is enough for the time being."He also exhaled deeply.

There are still several years before the night of extermination, and he still has enough time to stabilize his development.

"Training is done, go home and take a shower!" Kazuya stood up and left.

Anyway, only the first time you complete a 10-kilometer long-distance run, 100 sit-ups, push-ups, and squats every day will be effective. Doing them again afterwards will be useless.

Uchiha clan land. In a remote corner of Konoha Village.

Under the continuous suppression of the Second Hokage, the Third Hokage and other Konoha high-level officials, the situation of Uchiha in the village is becoming more and more difficult.

Even.

During the Third Ninja World War, the Konoha high-level officials also made the decision to let the Uchiha, who are good at fire escape, deal with the water escape of Mist Village based on the principle of"fire escape restrains water escape". It was really a bit crazy.

"Speaking of fire escape, the Sarutobi clan is also an expert. Why didn't the Third Hokage, that old monkey, let his clan members deal with Kirigakure?"

Kazuya sneered.

The Third Hokage was a pure double standard dog. He looked righteous on the surface, but in fact he was a black-hearted dog obsessed with power. He was a pure Hokage gentleman sword, a hermaphrodite.

Kazuya was the grandson of the Uchiha elder and had an independent mansion in the clan land.

However, he was not in a hurry to go home, but turned around and walked towards the clan leader's mansion.

Knock knock knock!

Knock on the door!

""Wait a moment, I'm coming!" A beautiful woman's voice sounded in the yard.

Soon, a beautiful woman with long black hair and a big belly opened the door eagerly.......
