Naruto: Starting by Extracting the Uzumaki Constitution

【Hokage + System + One Female Lead】After transmigrating as Genya Shiranui, a character no one in the original story had ever heard of, Genya is panicking. What? I have an Extraction System?! Then things are looking up! You have an Uzumaki constitution and tons of chakra? Let me extract that, and I'll have them too. You have a talent for ninjutsu and can learn any technique at a glance? Let me extract that as well. Years later, Genya says: That's right, I'm naturally gifted. These talents were all born with me.
