Three major things first:
One: MAJOR smut. I'm serious, this is going to have some hardcore stuff in it, including a fair amount of Non-Con for a large part of the story, if not all of it. You've been warned, additional warnings will be placed at the start of the worst (or best?) chapters.
Two: Not canonical at all, don't even try and think anything in here is going to come close to anything in the Anime or Manga. General relationships, locations, and characters will be the same, but the first warning above should let you know what I mean by non-canonical.
Three: Pay very close attention to the warning of the first chapter. It's important you read it and understand it, because it's where you'll either turn around and run, or continue to enjoy.
And of course, as with all things I write, I do not own any anime, nor manga I base this story off of- all canonical creations are the direct property of the original companies/studios that made them, please, respect that fact.
Onto the description!

[Note: The story begins at the start of Naruto's training with Jiraiya. But, in accordance with content rules, Naruto is gonna be 18 for this story. Other character's ages are adjusted accordingly too.]
Jiraiya sees the tremendous amount of latent potential within Naruto, but he sees the ninja is unable to both handle it, or bring it out voluntarily. Noticing this fact, he decides the best course of action is to throw Naruto off a cliff and into an abyss with rather razor-sharp rock walls! However, something quite unexpected happens...
As this is happening, Kurama himself sees quite the opportunity. The moment Naruto starts panicking, he couldn't be any luckier. The old fool Jiraiya has thrown Naruto into a situation where he needs the Fox's power to save his life- and Kurama has a need for something from Naruto as well...
Jungkook had always felt unlucky. Nothing ever went according to his plans.
But time travel was not something he'd ever imagined.
In 2024, Jungkook unexpectedly found himself in a time before South Korea existed, when it was still part of China. Suddenly, he was in the emperor's pool, face-to-face with a stern ruler. The emperor's first words to him were a chilling command: "Behead him."
