Invincible System of Time Travel

The black-bellied otaku had transmigrated into Naruto Uzumaki, bringing along the strongest system and creating the strongest harem. Cough cough ~ I said it wrong, create the strongest Naruto.

A certain otaku: " Wait, let me see what the daily mission is this time. Hmm, it’s very simple. Kick the third generation Naruto’s butt." Alright, I admit that you’re trying to trick me. Can Naruto’s butt be kicked by others? Even if I did, would the Dark Group let me off? God, who can save me?"

[I am God.]

A certain otaku:

"F * ck you. I’ll do it, okay? It’s just kicking your butt. What’s the big deal? In eighteen years, I will still be a good man.”
