In a small forest near Konoha Village, two teenagers were fighting fiercely hand-to-hand, and the sound of "popping" collision was endless. Although the two teenagers were not very old, they were obviously proficient in physical arts, and each move was extremely fast and powerful, bringing gusts of wind in the woods.

One of the teenagers was dressed in a green tights, with a funny mushroom head, a pair of thick eyebrows, and a nose much larger than ordinary people.

"Yusuke-kun, it's so much fun to fight you. But be careful, it's my last resort. Kai said to the other teenager with a sweaty face on his face.

The young man who fought Kai had black hair, a handsome face, and a pair of narrow eyes that were as calm as water. The boy is dressed in a Konoha ninja style vest, the forehead guard that symbolizes the Konoha symbol is tied to his left arm, and a red and white fan symbol in the center of the vest indicates the Uchiha clan to which the boy belongs.

"Konoha Rigid..."Kai yelled, and was about to make a move, when suddenly a teenager known as 'Yusuke' interrupted.

"Wait!" Yusuke made a gesture to stop.

"Are you scared of Yusuke-kun, did my Kai finally win you once in physical arts?" Yusuke Kaimi took the initiative to ask to stop, and cried with joy.

Yusuke said slowly, "Your attention is too focused on your opponent, and you have lost due alertness to your surroundings. Izumi is here, I have to go back to dinner, so that's all for today. ”

"Brother, mom called you home for dinner!" As soon as Yusuke's voice fell, a little girl's voice came from not far away. Then a little loli dressed in purple came out of the woods. Little Lori's name is Uchiha Izumi, Yusuke's younger sister, with long black hair, smart big eyes flickering, delicate and cute, and a beauty mole under the corner of her right eye.

Maitkai nodded disappointedly, he and Yusuke had already agreed that as long as Izumi called him for each competition, the competition would officially end. The reason why Yusuke set this rule is that Kai is too pestering, and once the rise of the fight is uncontrollable, he has to continue pestering himself, so he has to make an appointment with him in three chapters.

"Okay, then let's talk to Yusuke-kun next time!" With a big smile on his face again, Maitkai waved goodbye to Yusuke before running out of the grove shouting "youth". When he passed by Izumi, he grinned, a flash of big white teeth, and reached out to give Izumi a thumbs up.

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

Looking at Kai's back as he faded away, he kicked up a puff of dust. Yusuke shook his head and smiled, and stepped forward to pick up Izumi: "Izumi, let's go back to eat." ”

It's been fourteen years since Yusuke Uchiha came to the Hokage world, and he is a time-traveler from 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 rough plot, and many details he had long forgotten. And he wasn't very interested in the plot of the immortal fight in the later part of the Hokage, but he just read it hastily, and there was a lot of information that was not clear.

However, Yusuke knows the fate of the Uchiha clan very well. In a few years, the genius of the clan, Uchiha Itachi, will slaughter the entire family for the stability of the village, except for his own brother Sasuke, who will not be left behind. For this behavior of Uchiha Itachi, of course, Yusuke cannot tolerate it. Not to mention that he himself is a member of the Uchiha clan, his parents and sister Izumi in this life are his rebels, and he will never allow anyone to hurt him.

Therefore, in order to grasp the fate of himself and his family, Yusuke worked hard to improve his strength. Before the crossing, Uchiha Yusuke was a scientist with an extremely rich knowledge and scientific methods of learning and training. With a cognition far beyond his peers, Yusuke has consciously exercised his abilities since he was a child. It can be said that compared to most people, Yusuke has won at the starting line, and with his unremitting efforts, the growth of strength is even faster and amazing. In the eyes of others, Yusuke Uchiha is a rare genius, on par with the genius boy Kakashi of the same period.

Yusuke and Kakashi were both promoted to Shinobi at the same time not long ago, but the two don't have much in common. Especially some time ago, Obito and Rin died one after another, so that Kakashi, who was already arrogant, did not contact people outside the mission at all. Of course, in fact, Yusuke and Kakashi still have a certain connection, and both of them have a mutual friend - Maitkai. Perhaps this is also a common trait of proud people, although they have few friends, they are also happy to have a simple and trustworthy friend like Kai.

For Kakashi, Yusuke is very sorry. If it weren't for the series of blows in recent years, this genius would have achieved far more than the later generations of Naruto. The current Kakashi has barely continued to improve his strength, and is only anesthetizing his wounded heart through constant tasks. In Yusuke's opinion, Kakashi is simply squandering his talent like this!

Of course, it's a pity, and Yusuke doesn't have time to care about Kakashi. Now Yusuke is completely addicted to the world of ninjas, and the scientist's curiosity has prompted him to continue to delve into various knowledge related to ninjas. Although the rules of the Hokage world are not the same as many of the rules on the earth, for example, on the earth the hands swing staggered and run fast, while in the Hokage world the hands behind you do not move and run fast. However, the way of researching and thinking about problems is universal, and with Yusuke's knowledge as a scientist, it is natural to have a great advantage in studying various ninjutsu or some scientific training methods.

Holding Mei Koizumi, Yusuke walks along the country road and enjoys the time with his cute sister under the beautiful sunset.

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

"Oh? In the future, it is good that this kind of thing has not been heard, and there is nothing to argue about. Yusuke smiled and scratched Izumi's nose dotingly.

"How can this work, he said brother, you haven't opened the writing wheel eye yet, the so-called geniuses are all passed down from outsiders, and they are nothing in the Uchiha clan." Quanmei pouted and said angrily.

Yusuke laughed: "You girl, you are usually humble in everything, why are you competitive at this time." ”

"Others can be humble, but it's not okay to speak ill of you, brother. My brother became a shinobi at the age of fourteen.,Even if you don't write wheels, you're the strongest genius in the family.。 No, it's the strongest genius in the village. Izumi snorted.

Although Yusuke's strength far exceeds that of his peers, and he has reached the upper ninja, he has never opened the writing wheel, which is often criticized by some people in the clan. Most of the Uchiha clansmen are very proud, and to put it mildly is arrogant, especially for the writing wheels, they have a sickly sense of pride.

Many clansmen think that the Uchiha clan with the Sharingan is invincible, and Yusuke, who has not opened the Sharingan so far, is still a mediocre talent in the eyes of these people, even if he has strong personal strength. In their opinion, they can completely defeat Yusuke with their sharingan.

Yusuke himself was also puzzled about the delay in writing the wheel eye, so he also read a lot of historical materials and did a lot of research. In the end, it was found that the necessary condition for opening the eyes was a huge emotional stimulus, most commonly the person who cared about or oneself was in great danger, and only this kind of stimulation could make the writing wheel eyes open.

After understanding the conditions for opening his eyes, Yusuke had to smile bitterly. He had few friends of his own, and all of his family remained in the village without going on a dangerous battlefield. Because of his strength, he doesn't encounter many dangers, and he can always resolve them, so that he has become a ninja now, but the writing wheel has not yet been opened.

However, Yusuke didn't particularly care about this, because his real hole card was a weapon that accompanied him to the Hokage world, a weapon that did not belong to the Hokage world. At this time, in the depths of Yusuke's soul, a katana surrounded by raging flames was hovering in it.

The katana was slender and covered in flame-like moirés, glowing crimson in the flames. It is the strongest and oldest slashing knife in the fire and flame system in "Death" - the flowing blade is like fire!

Flowing Blade Flames usually sleeps in Yusuke's soul, and when Yusuke fights, he can summon it at any time. Because the flame characteristics of the flowing blade like fire have imperceptibly affected Yusuke for more than ten years, it also makes Yusuke's fire attribute chakra very abundant and pure. Yusuke is also very good at giving full play to his own strengths, and has focused on the development of fire attribute chakra and related ninjutsu over the years.

However, Yusuke can't fully control the flow blade, the power of this slashing knife is too violent, and he has just mastered the state of 'Initiation' not long ago. Although it was only the 'first solution', it also greatly increased Yusuke's strength, and he shined in the third ninja war, and won the title of 'Yan Tai Dao'.

When Yusuke returns home with Izumi, a table of simple but delicate home-cooked dishes is ready.

"Yusuke, I'm back, let's eat quickly. You kid is training too hard, and you're already forbearing, so don't push yourself too hard. Uchiha Hazuki said with a gentle smile. Uchiha Hazuki is the mother of Yusuke and Izumi, who looks around thirty, and has a seven-point resemblance to Izumi, but is much more mature than Izumi.

Yusuke put down Izumi in his arms, sat cross-legged at the dining table, and said with a smile: "Ninjas can't relax at any time, and if you work harder than you can, you may be able to save your life at a critical moment." ”

Hearing Yusuke's words, Uchiha Hazuki also showed a sad look on his face: "Many people have died in this war, and many familiar faces in the clan have disappeared all of a sudden, alas, I really don't know how long the major ninja villages will fight." ”

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

"I understand, don't worry." Yusuke answered seriously, then folded his hands and said, "I'm moving." ”

After Izumi sat down, she was also ready to start eating, and she also folded her hands and said, "I'm moving!" ”

In traditional Japanese etiquette, young and old, before eating, they should put their hands together and say "I'm moving" to show respect for food and gratitude for having food to eat.

After watching the two of them finish their dinner, Uchiha Hazuki took out a stack of black clothes from the house: "Tomorrow morning, a grand memorial service will be held to commemorate all the compatriots in the village who died in this war." I've got the clothes ready for you, so remember to change them when the time comes. ”

"Is it another memorial service?" Yusuke muttered.
