Naruto's Spirit Cultivation

My name is Shino, and I was reborn in the world of Naruto. I originally thought I would be so powerful, but I found that I seemed to have nothing special about me! Just when I was preparing to live an ordinary life, a system was activated: Ding~ The elf development system starts to activate~ Young man~ For a better future and for the countless elves around you, come and play the elf development game! What kind of elf do you like? Just cultivate it yourself! It was great to cultivate elves. When Jingo laughed with joy, a five-year-old white-haired girl suddenly appeared in front of him. She pulled his clothes very enthusiastically and called him in a sweet voice: Brother! Elder brother! A voice sounded in my mind: Novice training elves have been distributed! Young man~ Let's start the journey of elf cultivation! Let's raise the elves as soon as possible! What kind of elf development system is this? Also, what kind of elf is this?
