This fic is getting better and better. That was a smart move by the MC. Obtaining permission to leave. Now, he can collect power outside of the village without being labeled a missing nin. The MC should kill people that die in canon. Imagine Itachi walking towards Sasuke ready to touch Sasuke’s forehead and you swoop in and kill Itachi before he can die only seconds later.

Make sure to hunt down white Zetsu clone so you can move through the earth freely and transform into perfect imitations of other people like Mystique from X-men (even copying the chakra signature, smell, etc.).
