Absorbing...and more training...

Three years had passed since. Shiro had started to increase his training regime, and 100 pushups, sit ups, and 20 kilometer runs for3 years straight....

Kidding first thing Shiro did, was closed his eyes and entered his mindscape.

Then what he did was absorb as many Knowledge of Naruto techniques he can find inside his mindscape, the only thing he does when he is in there is. call the technique and then thousands of doors representing those techniques will come in, as there are a lot of people who write the same types of fan fiction and stuff, Shiro grabbed the door and opened it, before he started to assimilate the knowledge into his head...no never mind, it must pours in there, like pouring milk from a milk carton into a glass cup.

Yes it's a rush, and it causes quite the head trauma, but eventually, Shiro gets used to it, as he starts to open the next door and walk in, and then the next and even more so, he eventually gets used to it, and the knowledge stays fresh in his mind longer than normal if he doesnt go back for a couple of years, and the memories start to fade

Naruko won't get mad at him, shiro is techniquely not stealing, If Naruko does the move first shiro can just say that he can analyze it and make it into a version of his own.

Meh, anyway, Shiro also absorbed all of the versions and steps to make the rasengan ,all the steps to make the 8 gates of youth technique, all the versions and steps of the chidori.

and a lot of elemental chakra techniques...

Shiro wanted to hold off in the summoning, yes there is a category for that as well. thousands of doors to open, and knowledge of different versions, where to find the summon contract how do summon in the Naruto section.

Shiro read a lot of fanfictions...

Shiro glances at the senjutsu doors showing the diffrent types of senjutsu from different races and smiled briefly.

"I'll get to that later...." Shiro mumbled under his breath.

....

Just because Shiro has the knowledge on how to do it, doesn't mean trying to recreate it becomes so much more easier, quicker and smoother. I mean it does but it still a bit of a pain in the ass.

Shiro trained and trained, pushing his body passed his limits. to keep up with Naruko, who was also training with the Kyuubi and the aid of her parents memories and chakra.

During his training Shiro mastered most of the techniques that he had absorbed, his body wasn't ready to master some of the elemental techniques, the 8 gates,when he did 3 it was too much strain on his body's, he could only do two. He also created some techniques on his own

Naruko, was also training like Shiro, but she also had Kurama to help her which is why she is getting as strong as she is now, we are both about the same strength level

Naruko had increased her proficiency in seals, making her seals on her body even stronger and undetectable

Naruko had grown a lot, I hate to say it, even taller than me, it must be due to her fathers genes. she grew into a height of 4 ft 5 in.while Shiro grew 4 ft 7 in the baby fat was leaving her cheeks, becoming more pretty than before.

Her emerald green eyes shown like diamond's

What was Shiro doing now? He was walking her to the academy
