Naruto: Space-Time Lord

''Gramps, do you realize that Hanabi is just 7 years old? Maybe aging made you stupid instead of getting wiser?'' Asked Naruto with a small smile

Hiruzen wasn't angry with this at all as he said ''Age doesn't matter, Naruto, you said that your mission is to restore your clan, you see, there is many people that married a person 10 years older than him/her, stop freaking out''

Even though Hiruzen said this, Naruto won't agree, only if Hinata agree with this that he will do so, anyway, he excused himself and went to the training grounds.

'There's still five months and thirteen days before the Chuunin Exam begins, my chakra refining is slowing down but there's a steady progress, my body strength is also progressing slower than before, while the chakra refining can't be helped, I can increase the weights even more, improving my strength to be on par with a Sannin like Orochimaru without the need of using 'Kurama Chakra Mode' won't be that difficult... if I put more effort, defeating Orochimaru without revealing all of my powers will be enough, good, let's train!' Naruto thought to himself, his face was cold as the ice, he don't have any emotion when it comes to enemies or when he's alone.

It's like his subconscious block it when he isn't near his family and friends, after returning to the past, there's no reason to be emotionless towards his loved ones, however, his previous naivety of not killing was removed, the tragedy probably happened because of a enemy he spared, Naruto already thought of a person.

In the future, he never developed another releases rasengan, with his perfect chakra control, making it is easy, rotating his chakra, a sphere of chakra was made a little above his hand, with a thought, Fire element was put in it, soon, the rasengan began to change, exuding a fiery aura, it looked like rotating fire sphere.

Then, Naruto threw the rasengan towards a nearby tree, as soon as the tree was hit, it exploded in two before it was slowly burned into nothingness, the ground around the place it was previously had a black mark, he decided to name it 'Fire Release: Lava Rasengan'

Once again, Naruto create a rasengan above his hands and this time, he infused Water element inside it, slowly, the previously white-bluish became completely blue as droplets of water fell from it before completely falling from his hands, he knew that it failed.

Trying again, Naruto then began to rotate it in all directions, sure enough, it worked as a blue rasengan was made, there was four lines of water flowing around the rasengan, it looked very beautiful but also very destructive, this time using it on the ground, a crater was made with a huge pool of water in it, Naruto got curious in one thing so he stepped on it, his speed was decreased, he decided to name it 'Water Release: Slowing Rasengan'

Naruto already knew about the Lightning Release: Rasengan, Boruto had accidentaly created it and thought he failed after it disappeared but Naruto still think it is incomplete so he began to add more Lightning element, soon, there was sparks of lightning around the rasengan, it disappeared and after hitting the tree, a hole was made but there was still signs of lightning in the tree, touching it, his body was paralyzed for a brief moment, if he add enough chakra, it can be more useful, he decided to name it 'Lightning Release: Paralyzing Rasengan'

As for the Earth element, it turned into a dark brown rasengan, there was some rocks flowing around it, just like the water flowed around the 'Water Release: Slowing Rasengan', after it hit a person, a layer of rock would be 'put' where it hit, it could slow down the person, he decided to name it 'Earth Release: Rock Rasengan', don't judge, creativity has a limit, not that the others had a good name, though.

After creating these new rasengans, he decided that the Fire and Lightning Release rasengans would have a S-Rank while the Earth Release and Water Release ones could be considered A-Rank, still, having different trump cards are always good to get the enemy in surprise as he wouldn't know all of your jutsus.

Five months and thirteen days would pass by very quick so Naruto devoted himself to training everyday to his limits, his regeneration being what saved him from his 'everyday torture', once in a week, two males with green clothing would watch him while shedding tears.

Said and done, days turned into weeks and weeks turned into months as his training only got more and more intense, he even tried to merge chidori with rasengan but wasn't able to do so, probably because in these months, Naruto couldn't relax even one time, after finishing his training and clearing both mind and soul, he probably would be able to merge it, creating a powerful jutsu that surpass even S-Rank, with the time trying to merge it, his Lightning was almost turning purple, it isn't just a matter of knowing how to use Purple Lightning.

To obtain Purple Lightning, you first need to temper and purify it beucase it is a superior kind of Lightning, luckily, his talent is incredible high, otherwise, it would take many time, just like Kakashi, that although is a genius, it still took him many years.

The destined day came as Kakashi them, Naruto sighed in relief because his body was too tense after such intense and extensive amount of training, his current body can't take it lightly, then, he went towards the place where Kakashi called them.
