k let me explain this how i copy eyes is simple i take out a cuaple clones and one of them basically telaports your eye into his hand and the other clone, uses kage bunshin no jutsu on it, witch now makes 2 sharingan now that there are 2 of them. one of them is a clone theres the problem most ppl cant get past. but i can use my sealing techniques to seal the sharingan powers with-in the cloned sharingan, so now there are 2 fully working sharingan i can make more so ill make you an extra for youe other eye witch is missing one and i can also clone the rinregen that i have and give you one so now i give you an extra rinregen and sharingan
