Konoha: Give Millennium Kill Additional Attributes and Become Invincible

Traveling through the world of Naruto, I awakened to the unlimited upgrade system of Millennium Killer. I was invincible after giving Millennium Killer additional attributes at the beginning! After adding the "fire attribute", Thousand Years of Death comes with a burning sensation! After adding the "thunder attribute", Millennium Kill has a ** effect! After adding the "wind attribute", Millennium Killing has a sense of tearing! When Hyuga Chengdu added "all attributes" to the Millennium Kill, a new ninjutsu comparable to the Blood Succession Snare was born. Orochimaru: "I am immortal, but I wanted to commit suicide after being killed for a thousand years!" Uchiha Madara: "After experiencing it, I, Madara, would like to call you the strongest!" Uzumaki Naruto: "This guy actually opened his eyes and unleashed the Eight Diagrams Acupoint Thousand Years Kill on me! This feeling really makes me desperate for life and makes me feel like I'm in heaven." Uchiha Sasuke: "Please! Isn't it okay if I change my ways? Don't use... On me, ah!!!"
