I Just Traveled Through Time. System, You Want Me to Fight Naruto of Six Paths?

[The strongest ninja training system has been activated! In Konoha, Mizuki, who had just traveled through time, trembled when he heard the system announcement, full of expectations for this system that is said to cultivate the strongest ninja. [Mission 1: Defeat Naruto of Six Paths with physical skills, mission reward: Sage of Six Paths Yang Escape] … [Mission 601: Defeat Six Paths Madara with physical skills, mission reward: Ten-tailed Chakra] … Immortals are lined up like hemp! After reading all the tasks posted, Mizuki was dumbfounded. Putting aside the rewards, these tasks alone were either to defeat Nazusa, or to fight Madara Six Paths, Princess Kaguya, and even lower down to Kakashi, Metkai and others, not even a minion! He stared and asked: "What the hell? Isn't it the strongest ninja training system? Why is it that he is the strongest from the moment he comes up? Where is the training? Who is a good person who arranged this? " There was no movement, no response from the system at all. "Should I fight Naruto of Six Paths?" Mizuki rubbed his brows, suspecting that this system was created by evil capitalists. Until he saw the young Iruka and realized that he had traveled several years too early. Mizuki slapped his thigh violently and sighed: "That's okay, I'm good at bullying children!" Ps: This book is labeled as easy, invincible, and opening a harem.
