naruto time creation

I am reincarnated in naruto to carry the legacy of time by the god of time she said some thing that i cant comprehend. she said i was reincarnated at a great cost what did it cost her? why did she do it? for a mortal like me? is there something happening in the universe? Witness a mortals journey to control one of the strongest element know to the universe. I never new how hard it is too write until i wrote on my own but i will not give up and keep on writing till i lose my hope.
