Naruto: I Have Iron Fangs

Introduction: Let me tell you two important things. Good news, I traveled through time and it was the system that did it! Bad news, my system is down! But I'm not panicking. I'll tell you something quietly. You must never tell Namikaze Minato and the others! In fact, I still have a golden finger, which is Inuyasha's iron broken teeth. I don’t know how it appeared in my body. Maybe it found me when I traveled through time. After all, I am as handsome and beautiful as you! What drives it is no longer demon power, but chakra, and for unknown reasons, it has now turned into a rusty appearance, sleeping in my body. I need to constantly practice sword skills and understand the sword.
