unless you have proof genjutsu block are in his own live brain
you both have invalid arguments
lol ok here is how you remember when itachi touchesd sasuke forehead
lol
he just touches his own lmao its really that simple
your making this all complex and really unnecessary lol
like for real this is naruto so the way he got the genjutsu blocks in his pain bodies im pretty sure he didnt have to do surgery this isnt like the transfer of eyes its a genjutsu
or a jutsu at that
so as simple as how itachi put the jutsu in sasuke nagato can do to himself and
compared to riningan the tskuyomi is weak since
snake sasuke dojutsu beat itachis
and like zetsu said sharringan is a tool
a master can beat a pupil with a rock even though the pupil has a kunai
it matters on who ever is using the weapon!
