The remaining fire sword of Konoha

In a small forest near Konoha Village, two teenagers were fighting fiercely, and the sound of "snap" collisions could be heard endlessly.

Although the two young men are not very old, they are obviously proficient in physical skills. Each move is extremely fast and powerful, causing strong winds in the woods.

One of the teenagers was wearing a set of green tights, with a funny mushroom head, a pair of scary thick eyebrows, and a nose that was much larger than ordinary people. It was Metkai in his teenage years.

"Yusuke, it's so fun to fight with you. But please be careful, this is my last move." Kai said to the other boy, sweating profusely and looking happy.

The young man who fought against Kai had black hair, a handsome face, and a pair of narrow eyes as calm as water.

The boy is wearing the standard vest of Konoha ninja, and the forehead protector symbolizing Konoha's symbol is tied to his left arm. A red upper and lower white fan symbol in the center of the back of the vest indicates the family to which the boy belongs - the Uchiha clan.

"Konoha Gouri" Kai yelled, and was about to make a move when he was suddenly interrupted by a boy named 'Yusuke'.

"Wait!" Yusuke made a gesture to stop.

"Are you afraid, Yusuke, that I, Kai, have finally defeated you in physical skills?" Kai cried with joy when he saw Yusuke actively asking to stop.

Yusuke said slowly: "You are too focused on your opponent and have lost your due alertness to the surrounding environment. Izumi is already here. I have to go back for dinner. That's the end of the day."

"Brother, mother wants you to go home for dinner!" As soon as Yusuke finished speaking, a little girl's voice came from not far away.

Then a little loli in purple clothes emerged from the woods. The little lolita's name is Uchiha Izumi, and she is Yusuke's younger sister. She has long black hair, big and bright eyes that flicker, she is cute and cute, and she has a beauty mark under the corner of her right eye.

Metkai nodded disappointedly. He and Yusuke had made an agreement long ago. As long as Izumi calls him during each competition, the competition will officially end.

The reason why Yusuke made this rule was that Kai was too clingy. Once the fight started, he couldn't control it and would insist on pestering him to continue, so he made a three-part agreement with him like this.

"Okay, let's compete with you next time, Yusuke!" A bright smile appeared on Metkai's face again, and after waving goodbye to Yusuke, he shouted "Youth" and ran out of the woods.

When passing by Izumi, Kai grinned, his big white teeth flashing, and he stretched out his hand to give a thumbs up to Izumi.

Seeing this, Izumi smiled sweetly and gave Kai a thumbs up: "Come on!"

Looking at Kai's retreating back, waves of dust were raised. Yusuke shook his head and smiled, then stepped forward and picked up Izumi: "Izumi, go back and eat."

It has been fourteen years since Yusuke Uchiha came to the world of Naruto. He is a time traveler from the earth.

When he was on Earth, he had also watched Naruto and had a certain understanding of the entire plot, but it was only a general plot, and he had long forgotten many details. Moreover, he was not very interested in the story of the fight between immortals in the later stages of Naruto. He only watched it hastily, and there was a lot of information that he didn't know clearly.

However, Yusuke understood the fate of the Uchiha clan very well. In a few years, the genius of the clan, Uchiha Itachi, will massacre the entire family except for his younger brother Sasuke.

Yusuke certainly couldn't tolerate this kind of behavior from Uchiha Itachi. Not to mention that he himself is a member of the Uchiha clan, his parents and sister Izumi are his enemies in this life, and he will never allow anyone to harm them.

Therefore, in order to control the fate of himself and his family, Yusuke worked hard to improve his strength.

Before time travel, Uchiha Yusuke was a scientist in multiple fields, with an extremely rich knowledge reserve and efficient learning methods.

With cognition far beyond that of his peers, Yusuke has been consciously training his various abilities since he was a child. It can be said that compared to most people, Yusuke has already won at the starting line. Coupled with his unremitting efforts, his strength has grown even more rapidly.

In the eyes of others, Uchiha Yusuke is a rare genius, as famous as the talented boy Kakashi of the same period.

Both Yusuke and Kakashi were promoted to Jonin at the same time not long ago, but they didn't have many interactions.

Especially when Obito and Lin died in battle some time ago, Kakashi, who was already aloof and aloof, had no contact with anyone outside the mission at all.

Of course, Yusuke and Kakashi actually have a certain connection. They both have a common friend - Metkai. Perhaps this is also a common characteristic of proud people. Although they have few friends, they are happy to have a simple and trustworthy friend like Kai.

Yusuke felt very sorry for Kakashi. Without a series of blows in recent years, this genius would have achieved far more than he achieved in the original Naruto.

Now Kakashi hardly continues to improve his strength, but just anesthetizes his wounded heart through constant tasks. From Yusuke's point of view, Kakashi is simply squandering his talent!

Of course, it's a pity that Yusuke doesn't have time to care about Kakashi. Now Yusuke is completely addicted to the world of ninjas. The scientist's thirst for knowledge prompts him to continue to delve into various knowledge related to ninjas.

Although the rules of the Naruto world are different from many rules on Earth, for example, on Earth, you can run fast by swinging your hands intertwined, but in the Naruto world, you can run fast by placing your hands behind your back without moving. However, the way of researching and thinking about problems is universal. With Yusuke's knowledge as a scientist, he will naturally have great advantages in studying various ninjutsu or some scientific training methods.

Holding Koizumi in his arms, Yusuke walked on the country road, enjoying the time with his lovely sister under the beautiful sunset.

"Brother, there was a little boy today who said you were not a genius. Izumi and him had been arguing for a long time. My brother is the best!" Izumi said while being held by Yusuke.

"Oh? From now on, just pretend you haven't heard anything like this. There's nothing to argue about." Yusuke smiled and scratched Izumi's nose lovingly.

"How can this be done? He said that brother, you haven't opened the Sharingan yet. The so-called geniuses are passed down from outsiders and are nothing to the Uchiha clan." Izumi pouted her mouth and said angrily.

Yusuke laughed: "Girl, you usually give in to everything, why are you so competitive now?"

"You can be humble to others, but you can't say bad things about me, brother. He became a Jonin at the age of twelve. Even without the Sharingan, he is the strongest genius in the family. No, he is the strongest genius in the village." Izumi He hummed.

Although Yusuke's strength far exceeds that of his peers and he has reached the level of jounin, he has never opened his Sharingan, which is often criticized by some people in the clan. Most of the Uchiha clan members are very proud, to put it bluntly, arrogant, especially they have a pathological sense of pride in the Sharingan.

Many clan members believe that the Uchiha clan with the Sharingan is invincible, but Yusuke, who has not yet opened the Sharingan, is still mediocre in the eyes of these people, even if he is very strong. In their opinion, with the Sharingan, they can defeat Yusuke.

Yusuke himself was quite puzzled about the delay in opening the Sharingan, so he read a lot of historical materials and did a lot of research.

In the end, Yusuke discovered that the necessary condition for opening the eyes is a huge emotional stimulation. The most common thing is that the person you care about or yourself is in great danger. Only this kind of similar stimulation can make the Sharingan open.

After understanding the conditions for opening his eyes, Yusuke had no choice but to shake his head.

He has few friends, and all his family members have stayed in the village and have not been to dangerous battlefields. Because of his extraordinary strength, he rarely encounters many dangers and can always resolve them, so that he has become a Jonin now, but his Sharingan has not yet been opened.

However, Yusuke didn't particularly care about this, because his real trump card was a weapon that accompanied him to the world of Naruto, a weapon that did not belong to the world of Naruto.

At this time, deep in Yusuke's soul, a katana surrounded by blazing flames was suspended in it.

This samurai sword has a slender blade, covered with flame-like cloud patterns, shining with red light in the raging fire. It is the strongest and oldest fire-type Zanpakutō in "Bleach" - —The blade is like fire!

Ryukenwaka usually sleeps in Yusuke's soul, but when Yusuke is fighting, he can summon it at any time.

Because the fire characteristics of Ryukenwaka have been subtly influencing Yusuke for more than ten years, it also makes Yusuke's fire attribute chakra very abundant and pure.

Yusuke is also very good at using his own strengths and has focused on the development of fire attribute chakra and related ninjutsu over the years.

However, Yusuke is not yet able to fully control the Ryukenwaka. The power of this Zanpakuto is too violent, and he has just mastered the state of 'Haijie' not long ago.

Although it was only the 'Hajiki', Yusuke's strength greatly increased, and he shined in the Third Ninja War, earning the title of 'Entachi'.

When Yusuke brought Izumi home, a table of simple but exquisite home-cooked meals was ready.

"Yusuke, you're back, hurry up and eat. You just trained too hard and are already a jounin, so don't push yourself too hard." Uchiha Hazuki said with a gentle smile.

Uchiha Hazuki is the mother of Yusuke and Izumi. She looks about thirty, and her appearance is similar to that of Izumi, but she is much more mature than Izumi.

Yusuke put down Izumi in his arms, sat cross-legged in front of the dinner table, and said with a smile: "A ninja can't relax at all times. If you work harder at ordinary times, you may be able to save your life at critical moments."

Hearing Yusuke's words, Uchiha Hazuki also showed a sad look on his face: "Many people died in this war, and many familiar faces in the clan suddenly disappeared. Alas, I really don't know how many great ninja villages there are. How long are we going to fight?”

"Although you are a Jonin, the ninja world is too dangerous, so you must be careful." Uchiha Hazuki continued to tell Yusuke.

"I understand, don't worry." Yusuke responded seriously, then clasped his hands together and said, "I'm starting."

After Izumi sat down, she was also ready to start eating. She also clasped her hands and said, "I'm starting!"

In traditional Japanese etiquette, regardless of age, everyone should put their hands together and say "I'm starting" before eating to show respect for the food and gratitude for having food to eat.

After watching the two of them finish their dinner with gentle eyes, Uchiha Hazuki took out a pile of black clothes from the house: "Tomorrow morning, a grand memorial service will be held to commemorate all the compatriots who died in this war in the village. I have prepared clothes for you, remember to change into them when the time comes."

"Is it another memorial service?" Yusuke murmured.
