9 years pass by Naruto stayed in the land of foxes practicing various things. He gained complete mastery over Fūinjutsu and started creating a various seal on own his with the help of Hope. He also created his computer and analyzed the blood of 1st 2nd and Mito Uzumaki. After 6 years of deep research into DNA genetics, Naruto finally broke down the mystery of bloodlines. after analyzing everything. He focused on two things only first learning Senjutsu, secondly learning and creating new Jutsu, as the use of chakra was limitless. He also remembered that the Uchiha massacre will be happening soon so he decided to cash in too. Soon after Tobi and Itachi were done killing people, Naruto stored the body of one sample each one kid who hasn't unlocked the Sharingan one who has unlocked it one who has unlocked all three totems and finally the one who has unlocked Mangekyo Sharingan. after collecting his share naruto went back to the land of fox and started analyzing the blood at a different level again. He also ordered one of his foxes to be on the lookout of any Hyuga members who are going out on their own. Soon after only three days of wait, one of the branch members went out. Fox named Roi quickly informed naruto who made a Rasangen and waited for the next phase of the plan foxes around the forest started leaving leaves on the floor, Leafs with seals on them. As soon as the branch member went close to the leaf naruto appeared in a flash and embedded Rasangen right into the heath of the Hyuga. Picking up the body of the now-dead Hyuga naruto placed it into a storage scroll and then along with all the foxes disappeared.
Within 7 years Naruto has understood the concept of bloodline and how it changes and was sure he can change and modify his own but for the moment decided to focus on 2 things alone first complete chakra control second creating and doing Jutsu of various elements.
When he reached the age of 11 he has completed all his goals and sent one of his foxes to spy on Tazuna the bridge builder. Roi followed Tazuna from the land of waves to the Konoha and informed Naruto about the progress. Naruto too got excited finally achieving the thing he has been looking for. Following days Roi reported the team of Kakashi along with Sasuke, Sakura, and Hinata leaving the village. Naruto too decided to wait along till the final battle at the bridge. after Kakashi got trapped in the water bubble, the rest of the team turned useless. Sasuke in his arrogance rushed to attack alone meanwhile Hinata and Sakura stood by Tazuna. Kakashi seeing Sasuke running alone decided Now or never moment and used his Mangekyo Sharingan and created a gape in the water buddle freeing and then attacking Zabuza who was distracted due to Sasuke. Soon Yuki comes up in the form of Hunter nin and took injured Zabuza away. Meanwhile, Tazuna carried Kakashi and went to the land of waves along with the rest of the team. Naruto watching all this wanted to beat his head against the wall, about how useless everyone in the team is.
One fine morning naruto sleeping in the grass is awakened by Haku. Naruto seeing that it's Haku attacks him using sleeping powder. and quickly with his speed put Haku to sleep. After collecting a tube of Haku blood. Naruto left Haku sleeping on the ground and went away soon after 15 mins or so Haku gained consciousness.
Naruto hiding in the shadow waiting for the battle to begin soon Zabuza along with Haku appear but this time Kakashi and his team didn't appear alone but brought along team 8 which consists of Kurenai Yūhi as leader Shiro Kiba and Amell Hyuga as it's a member.
Soon the battle starts with Zabuza taking on injured Kakashi and Kurenai alone while Haku taking the genins of both teams 7 and 8. Hinata along with clan member Amell went to protect the client using Byakugan. Sasuke already alone rushed toward Haku along with Kiba who though of the battle as a game. Shiro maintained a small distance and observed the battle meanwhile sakura just stood in her position looking pretty. The battle was very boring. Zabuza alone was enough to hold both Kakashi and Kurenai Haku played with little genins for a while making Sasuke fare one totem Sharingan over his hatred of being powerless. Naruto got bored after a while and decided to Jump in the battle.
Naruto wearing a lit Blue t-shirt and black jeans and sports shoes jumped in the middle of Zabuza and Kakashi fighting Kicking both Mid air and creating a distance between the two.
Zabuza and Kakashi both got stunted seeing someone pop out of nowhere.
Naruto moved to Zabuza: I need half of that sword so why don't you give it to me? I will leave after that.
then turned his face toward Kakashi: Is the old man dead yet? Should I come back to kick his grandson on the street?
Zabuza quickly recovered and screamed: Over my dead body kid
Naruto shook his head and disappeared appearing in front of Zabuza the very next second with a Rasangen in his hand implanted it into Zabuza's stomach.
Zabuza suddenly felt his muscles twist and finally break into many pieces.
Haku ran toward Zabuza as soon as he saw his conditions.
Naruto ignoring everything picked up the sword and started measuring it.
Zabuza broke his last breath in Haku's arm, making Haku go into a crazy state and rushed toward Naruto who kept examining the blade. As soon as Haku was ready to attack Naruto, Naruto simply swept the sword in diagonal form. Naruto: I left you alive once already. If I leave you alive now too, people will take it as a bad example so bye-bye I guess.
Naruto nodding his head appreciation the blade moved his gaze toward Kakashi: I would also need that Sharingan you have, will you give it too me or I have to take it?
Kakashi: Naruto, Come back to the village we can sit down and talk
Naruto: Man, You all could have locked me in a prison trained into a weapon or at worst make me a mindless tool but you guys shouldn't have left me to eat on the street. That did a number on me. Well anyway, I heard your father white fang was famous for swords so did you learn anything from him?
Kakashi: Naruto for what we did we are sorry to come back to the village, Hokage sama will explain everything to you.
Naruto: I'm bored, So Kakashi Sharingan or you precious students and then I will ripe out the Sharingan myself?
Kakashi: Naruto this was a gift from my dead friend I can't under any condition give it to you.
Naruto nodded then rushed to injured Sasuke awake him by twisting his hand and collected his blood in a tube: Man Blood from a living Uchiha, dream come true. Itachi was so sad when I brought up the topic of killing Sasuke, He almost revealed the secret. How Hokage along with Danzo forced him to kill everyone in Uchiha clan while they hold his little brother as their Hostage. It's kind of funny don't you think about how you want to kill the only person who is hellbent on saving you? Hahahaha
Sasuke eye's wide open as he heard naruto spoke about Itachi.
Naruto: Well anyway, Next time you see Itachi tells him to come and eat my shit or else I will kill you. Hahahaha knowing Itachi he might do it to keep his idiotic brother alive.
Kakashi: Naruto don't speak nonsense
Naruto: How am I speaking nonsense? Isn't it true that Itachi is currently acting like a dog for the Hokage who's job is to go into S criminals who can kill him anytime they want and provide information on them in exchange for baby Sasuke's good night sleep.
Naruto throws Sasuke away while speaking: Anyway, Sharingan or your students?
Kakashi pissed at naruto reveling an S rank secret: Naruto If you want to talk then talk if not then fight
Naruto next moment disappeared and a rain of blood come out. Sakura's body split in two one head and then rest of the body.
Kakashi stunted to see naruto killing someone.
Naruto turned around and saw Kurenai trying to activate Genjutsu, Naruto just smiled at her: I'm what people call a monster Kurenai sama Genjutsu doesn't work on the little old me.
