In the Hokage World, but Why Is the System Living in a Fantasy World?

The protagonist transmigrates into the body of Naruto’s classmate. At this point, Naruto has failed to graduate and is about to steal the Scroll of Seals. “Ding! Congratulations, Host, you have transmigrated to the Xuanhuang Realm.” What? A fantasy world? Wasn’t I in the Hokage world? Lin Yu wondered. “Your cultivation has been raised to the Third Realm. You’re a newbie, so watch out for being killed by some passerby!” The Third Realm is already a Jonin, isn’t it? I’d be doing well if I didn’t kill anyone else. “Quest complete. Reward: meridians expanded by 25 times!” Standing atop a slug more than a thousand meters tall, Lin Yu said to Naruto, “I want to see how our chakra stacks up.” What? The Hyuga Clan’s Caged Bird Seal is impossible to remove? Then watch me use a curse-breaking pill from the fantasy world. You have a Tailed Beast? Then behold my imperial-grade bloodline: the Violent Panda! Eight Gates? Then face my purely physical strength. I’ll send you flying! Susanoo? Then behold my Law Avatar, a golden giant!
