The academy library was as disappointing as Rei had expected, most of the stuff there was regarding the history of leaf village which although he didn't mind reading it wasn't what he really wanted.
"No wonder there are no kids in the library."
Looking around the library he finally found a the jutsu scroll section. He looked through them and a smile formed on his face
"Transformation jutsu, Clone jutsu, Substitution jutsu, Shadow Shuriken jutsu, good these will be do for now."
He picked up all the scrolls and started reading them after taking a seat in a corner.
After a while Rei closed the book and performed some hand signs while focusing on his chakra flow.
Ram > Snake > Tiger
"Clone jutsu."
*poof*
Rei smiled in happiness as he looked at his lookalike copy standing in front him, he willed and the clone also smiled back at him.
Having acquired what he wanted Rei left the library for his home.
In the academy ground he looked at Guy running around and waved him goodbye who also smiled and waved back at him.
A serious look appeared in eyes as he left the academy ground. Looking at Guy and Kakashi again reminded him that he needed to work much harder if he wanted to be in a position of being unmatched.
'Not to mention there might be more prodigies or stronger people that he didn't know about.'
He remembered reading about how the first hokage Hashirama was unmatched, that he was so powerful he could grow forests out of nowhere.
But soon a smile returned to his face as he had enough confidence in himself. He wanted to be the strongest as only the strongest ever have a choice and the weak could only follow the choices made for them.
He remembered the past when he was weak and helpless, as all he cared about ceased to exist and how all he could do was watch. Although he was in new world he had already learnt his lesson.
...
At Rei's home
After eating and talking with his mother who asked how his day was and if he made any friends Rei told her that he had a good day and had already made friends he continued to train his body with weights added to his body.
He also setup targets in the compound to train with his ninja tools like kunai and shuriken since they were also great help in ninja battles and there were many jutsu aimed to improve their use in battle like the shadow shuriken jutsu he learnt.
At night he trained his chakra and practiced the jutsu he already knew plus the new substitution jutsu that he just learnt.
Having exhausted both his body and mind to the breaking point he finally went to sleep.
..
Miso looked at peaceful face of sleeping Rei and sighed.
He was growing too fast, it felt like it was just yesterday when he was falling around and crying only for her to embrace him to calm him down.
Although she was worried when she saw him train so hard she also felt proud at the same time, and if he had really decided to become a ninja with all his heart she too decided that she would support him with all her heart.
She closed the door to Rei's room and went back wiping a few tears from her eyes.
