"Ha there is nothing in here."
After a few days of reading books continuosly in the library and satisfied with his information about this world's history Rei was eager to learn more about chakra and how to use it but all he could find here was history there was no knowledge about how to use this chakra.
He tried asking if his shinobi father had left any books but weirdly Miso smiled shyly saying he wasn't a books type of person.
Since chakra and mana were quite different entities Rei didn't want to apply the methods of mana circulation to chakra until he was really desperate. Since it could carry some risk it was always better to be safe than sorry.
Frustrated he went to the librarian to ask where he could get what he wanted.
"Hello Rei did you need something."
Thr librarian greeted Rei as he saw him approach.
"Mister where can i find more books about chakra control."
The librarian wasn't really sure if Rei was actually reading the books even if he was here for a stroll he didn't mind since everybody was allowed here as long as they didn't cause any trouble.
"Well there are no books here about chakra control, but if you want read about or see pictures of our kurama clan great ancestors i can help you find them."
'Fuuh I don't really care about those dead old men.'
Holding the urge to tell him just what he asked for Rei smiled innocently.
"But i really want to read about chakra control mister."
"Hmm those book are only for ninja's Rei, not everyone is allowed to read them according to the village rules."
'Rules hmm makes sense, but its still frustrating.'
"And how do i become a ninja."
Rei asked in an exited tone.
"Hmm for that you have to enroll in the village academy. But you must know that not everyone is accepted into the academy you have to have.."
..
"Also our great kurama cla..."
The librarian who had unknowingly closed his eyes while explaining this and that became speechless as he opened them to empty air.
"Whew kids these days have no patience."
...
"Academy huh, guess i know where i will be going next."
Rei thought out loud in excitement as made his way home.
It was his childlike excitement and curiosity towards gaining knowledge that had led him to be the strongest in his previous world and it seems he carried those traits with him to this world as well.
