Welcome to the newest chapter of Naruto: Rewind! I do not own anything but the story itself!

Naruto was keeping to a similar height to Sasuke, so as not to give away any of his true strength.

On her second try, Sakura finally made it to the top.

"Hey Kakashi-sensei, I made it!" she exclaimed happily as she glanced down at Naruto and Sasuke, Naruto responding with a good natured thumb's up while Sasuke gave a slight grunt of approval.

Kakashi looked up from his book, almost astounded that Sakura has such chakra control for her age.

"Very good Sakura, now let's focus on some simple strength training while the boy's finish up," Kakashi responded as he placed the book inside the back of his pocket.

Sakura gave Kakashi a nod as she began to train, Sasuke and Naruto resuming their own training.

In a mere couple of hours, Sasuke and Naruto had gotten the basic's of the tree climbing exercise down, managing to climb to the top of the tree as Sakura did. As Naruto and Sasuke finished up, Sakura was completing her strength training as well.

"Alright, let's go over one more exercise before I send you all home," Kakashi interjected as the shinobi prepared to pack up their belonging's to return home. "Since I have you all here, I'd like to administer a little test. Don't worry, their isn't a way that any of you can fail, so relax. It's simple, I want each of you to take a slip of this special paper. Concentrating all of your chakra into that slip of paper, I'd like to see all of your chakra nature's so I know what I'm dealing with."

Naruto let out a slight scream as he listened to what Kakashi was explaining to him. In his time, he had mastered most of all the release's, including the Wind, Water, Fire, Lightning, Earth, even the Ying and Yang release. So if he was tested, the paper would do a whole lot more than it was supposed to do for a mere genin. Naruto shrugged as he took the sheet of paper from Kakashi's hand. He knew he to, or risk looking even more suspicious when he denied the paper. Naruto circulated his chakra through the paper, the paper first slightly cutting in the middle. Then it went damp, followed by crinkling in several area's. Then it went on fire, followed by turning into dust. Kakashi, Sakura, and Sasuke looked on in awe as this occurred, Kakashi absolutely speechless.

"How did you… you have all nature type's!" Kakashi stammered as he looked at Sakura and Sasuke's paper, which were doing absolutely nothing. But Sasuke's crinkled in several area's, then lit itself on fire.

"You have the lightning release along with the fire release, as expected from an Uchiha," Kakashi told Sasuke, who seemed quite pleased by this discovery.

"What about mine Kakashi-sensei?" Sakura asked, her paper not even slightly touched.

"Your type is undetermined right now, it will become clear after you develop as a shinobi," Kakashi explained to her, which seemed to relieve the kunoichi. "Naruto, you might be the only genin in history to ever have all chakra nature's at your age. This is groundbreaking, there is so much to teach you!" Sasuke grunted unhappily as he tried to swallow this news. Naruto was just t advancing past him, so easily in fact. It seemed like the once troublemaker has turned into a superstar overnight.

"Kakashi-sensei, what can you teach me?" Sasuke asked, Kakashi rubbing his chin slightly as he thought of a jutsu that would suit the Uchiha.

"I have a jutsu I can teach you that is very powerful Sasuke, but you're not ready yet to learn it," Kakashi answered, Sasuke growling slightly at the answer he received. "Be patient, your time will come. But for now, just focus on building your strength."

Sasuke gave Naruto a questionable glance as he packed up his training gear, taking off toward the Uchiha compound while Naruto and Sakura stayed with Kakashi. He was determined to get stronger… even if he had to do it on his own.

After getting back to her house, all Sakura felt like doing was getting some sleep, but shek new she had to train. The kunoichi settled with getting a quick bite to eat before taking on the training. As Sakura chewed thoughfully on a banana, she thought about the developing Naruto, who was beginning to cause Sasuke to go into his shadow. Though she did not want to admit it, Naruto had really improved, from being the worst student to acceling at almost everything he tried. But Sasuke was still her heart, and she was determined to win his love by showing him a true kunoichi. She began her strenuous workout, doing everything in the intermediate Academy training book. She did the same as the previous day. After finishing her workout, she practiced on building up her stamina and reserves by running up and down a tree. After she finished all this, it was around seven o-clock, so she went inside and took a shower, then collapsed on her bed, and was asleep in the matter of seconds.

Meanwhile

Sasuke had come home, or at least to where he lived, in a slightly better mood, from not having to deal with Sakura pestering him for a date all day. He then proceeded to do his normal workout. 120 pushups, 100 squats, 100 pull-ups, and ten laps around the Uchiha training grounds. After that, he decided he wanted to learn a new jutsu, forgetting completely about what Kakashi spoke about earlier.

After searching through the files of various fire release jutsu's in the Uchiha library, and a few new lightning release type jutsu's, he came across a technique called Fire Release: Flame Barrier. It was a type of ninjutsu that allowed the user to build a wall of intense flames around themselves, a good defensive type ninjutsu. Sasuke liked the sound of that, but after reading over the instructions, he also found out the user must have a very high level of chakra. It was not a type of ninjutsu for a genin, who has very limited chakra, to be wasting time on. So after searching through a few more jutsu, he came across a C-Rank lightning release jutsu. It allowed the user to charge up a ball of lightning in his/her hand, then launch it at an opponent in a bolt of lightning. He memorized the hand signs, and then went to the training field to perfect it.

The first time he tried it, he sent 500 volts of electricity through his body, paralyzing him for a few minutes. After recovering from that attempt, he tried again, this time going at a much slower pace. A orb of lightning started to form in his hand, after reaching about baseball size, he aimed his hand at a tree about 50 yards away, then the lightning bolt shot from his hand, but only made it about 10 yards, before fizzling out.

He growled in frustration, but went through the hand signs again. After forming a slightly larger lightning ball in his hand, he shot again, making it about 15 yards.

Time skip 2 hours later

After two hours of constant practicing, and a chakra and food pill, he had managed to get it to go the full fifty yards he had been targeting. Tomorrow he was going to try to get the full distance that it had stated in the instructions, of 150 yards.

Meanwhile

Naruto, after Kakashi had dismissed them, had went to the training ground 44 to practice so he wouldn't be disturbed. The only person he knew that was in these woods a lot was Anko, and he could sense her, or anyone else for that matter in time to escape.

He then came out of his henge, (I'm just going to say henge, but when I do I mean he is shapeshifted.) and made several hundred clones. As soon as they came into existence they got to work, some on chakra control, some on jutsu, some on physical exercise.

He then started on his own training, and noticed several changes to his body, so he stopped his training so he could go visit Kurama and find out what exactly he did to his body. He sat down in lotus position and concentrated.

Mindscape

Naruto appeared in his mindscape, and made his way across all the winding paths until he eventually found Kurama, who was sleeping as usual.

"Seriously, is all you do is sleep?" Naruto asked accusingly.

"Well if I had something else to do in here, I might not sleep all the time!" Kurama replied with a snort. "Well, what is the reason that you graced me with your presence?"

"I just wanted to know what all exactly you did to my body?" Naruto asked, as he took a seat in a chair that rose from out of the ground.

"Ahh I see. Well where do I begin, I altered your muscles, making them much denser, making them learn muscle memory faster, as well as not atrophy. I altered your eyes and nose to be of that on par with an Inazuka's, and your eyesight, during the day will match anyone's, and at night only someone with a very powerful Sharingan could beat you. I've increased your reflexes to be nearly on par with someone with a Sharingan. I doubled your healing factor you already had. I've also altered your chakra network, so now you can handle all of my chakra with ease, though it will require a week or two of recuperation after doing so if you go above a certain amount. But I do not see you ever needing to use my power again, but I figured while I was at, why not," Kurama explained with a smirk.

As the blond shinobi hadn't used his chakra in over three years now.

"Also I've made your bones denser, making them nearly impossible to break for anyone under Kage level. I've also increased your field of vision slightly, but nothing too noticeable," Kurama continued, clearly happy with his work.

"Oh, is that all?" Naruto deadpanned, clearly not expecting Kurama to change so much.

"One more thing, if you have any children, this will pass on to them, although over generations, it will get weaker." Kurama replied offhandedly.

"So it will be passed on like a bloodline?" the blond shinobi asked curiously.

"Yes, but unlike a bloodline, of which you only really need basic ninja abilities, which makes clans like the Hyuuga and Uchiha rely on them so much, your abilities will only be a small aid in battle, compared to others, much like the Nara's 'shadow' bloodline, it is nothing without shinobi skills to match it."

"Great, I like it, it also prevents my descendants from coming to rely on it like the Hyuuga or Uchiha. Well that's all I wanted Kurama." Naruto said as he turned around and was about to leave the mindscape.

"By the way Naruto, I've also been trying to unlock a dormant Kekkai Genkai that is inside of you," Kurama added, making Naruto turn back around. "I don't know what it is, it's more likely to be a visual prowess like the Sharingan or Byakugan, but it could also be the fabled Rinnegan."

"You mean what Nagato had?" Naruto asked, Kurama nodding in response.

"Yes, you are an Uzumaki just as Nagato was, you are a direct descendant of the Senju clan, meaning you would have the blood to be born with the ability. The first one to ever wield this was the Rikudo Sennin."

"Kakashi-sensei always's told us that the Rikudo Sennin didn't exist, that the Rinnegan was just a mutation," Naruto responded, Kurama giving him a hmph.

"The Rikudo Sennin is not a myth! When I was just a fledgling, he taught all of us Tailed Beast the meaning of life, though we all did take a different path than he anticipated," Kurama stated, a certain nostalgic look going on the fox's face. "He was like our father… he was also the most powerful man to ever exist as well. Naruto, you yourself have the ability to mirror the Rikudo Sennin in power one day, but you must continue to train. I'll keep trying to unlock this while you figure out how to get us back to our time."

"Deal, let's do it together Kurama," Naruto replied as he left from the mindscape, a smile crossing his face as he did. "By the way, thank you for everything."

"You're welcome….Naruto," Kurama said as he drifted back to sleep.

When Naruto woke up, he looked around and saw it was already 8 o-clock. He had his shadow clones, and chakra clones dispel in small groups, while he made his way back to his apartment.
