Making him a kid and doing this skip and nerf is more frustrating than him being reincarnated into an adult. I'm just unwilling to read any further if he doesn't come out of this situation much more powerful than he was before.
Author keep this up I love the story of the Mc struggling and grinding to his goal. Ignore everyone else because Zeus goal was to find his way back to being a God and not about affecting the world around him.
Sorry but I don't think orochimaru would Doo it dis way, why did he think his body was special it's his chakra/lichtning controle not his body and why didn't orochimaru research his body and the reason for his power , because the only thing special about him is his jonin amount of chakra
