1. I said god-level genjutsu
2. Chakra mode is two chakra sources mixed together. Logically, if you infect the chakra mode with a god level genjutsu chakra, you infect the two chakra sources that make that chakra mode. At this point, the only way naruto could break out of a genjutsu if he take in NE to override the infected chakra flow.
So unless you're calling god-level genjutsu fodder now, I don't see it happening.
You still ignore the very basic element of how Genjutsu work then i will just drop you there. No need to argue anymore.
