Changes
"Naruto Uzumaki?" a one-eyed man dressed in strange clothes said, surprising the three genin who hadn't noticed the man approach the bridge they had claimed for their team meeting place.
"Who's asking?" Naruto demanded, kunai in hand.
"No time, I have only a few minutes to give you as much information as possible," he said. "Let's start with your bloodline."
"He has a bloodline?" Sakura asked doubtfully.
The one-eyed man ignored her. "You are a mainline Uzumaki," he said. "That means fast healing and longevity aren't your only gifts."
"Longevity?" Naruto asked.
"It takes longer for you to get old," he quickly summed up. "Of course, Uzumaki are noted for rushing in where other people are cautious, so it's never been obvious."
Kakashi appeared in a swirl of leaves but when he attempted to put a hand on the man's shoulder it passed right through.
"Now, as a mainline Uzumaki you also have the ability to make chains with your chakra, and you're wind natured like your father," he explained
"Stop!" Kakashi ordered, before pulsing his chakra to find and tear the genjutsu that he figured was hiding this man.
"Who are my parents?" Naruto begged.
"The third Hokage knows but swore to your father he wouldn't tell you until you could protect yourself from his enemies," the one-eyed man explained.
"I-I…" Naruto fell silent.
"Anyway, back on track. Figure out how to make chains with your chakra and you can restrain ninja with them. Start learning seals too, it's in your blood from both Uzumaki and Senju lines."
"He's related to the Senju?!" Sasuke blurted out.
Kakashi scanned the area, looking for the hidden ninja.
"Kakashi won't train you, not because he's malicious, but because he's an idiot," the one-eyed man said.
"Hey!" Kakashi protested.
"He was a genius who made jounin in a ridiculous amount of time, but that doesn't mean he knows how to train people, plus he has some warped idea about keeping you as kids longer and preserving your childhood that just makes it more likely that you'll die, and it's not like you or Sasuke had much of a childhood anyway."
"Huh," Naruto said thoughtfully.
"You get the memories of shadow clones when they disperse," he told Naruto. "So if you have five shadow clones walking one mile each, how far have they covered?"
"Five miles?" Naruto asked excitedly.
"No, only one mile," he corrected him, "but in five different directions, while you walk a sixth. That's a hint, by the way."
"I'm confused," Naruto said.
"You can learn a number of different subjects at once, but not a bunch about one specific topic, using shadow clones. I'd suggest spying on everyone's training, and using henge to get access to places that aren't very helpful to you."
"Who are you, and where are you?" Kakashi demanded.
"Oh, and letting Sakura hit you will lead to her death as she lets her temper get away from her and gets killed for it."
"What?!" Sakura and Naruto chorused.
"Of course, to save her life you'll have to kick the crap out of her every time she hits you until she learns to control her temper. That would require you deliberately goading her into it and ruin any chance you have of dating her, so I doubt you'll do it."
"I'll do it!" Naruto swore. "For Sakura's life's sake, I will do it, I promise, and I never go back on my word!"
"My time's up, live well," the one-eyed man said before vanishing.
"Well, that was surreal," Kakashi said, adjusting his headband to cover up his Sharingan eye before someone noticed.
"Kakashi-sensei, do you know who my parents are?" Naruto asked.
"I'm not at liberty to say," Kakashi replied.
"I'm not asking you to tell me," Naruto said, "I'm just asking if you know."
Kakashi winced, but Naruto just smiled.
"Just making sure jiji ain't the only one," Naruto said.
AN: If you had three minutes to make changes to the timeline what would you say?
