Flying Thunder God Technique II.

Hiruzen led Dix inside from the cold and they walked together to the Hokage's Office in silence. Upon entering the Third moved straight to one of the cabinets, opened it, and pulled a huge sealed scroll out of it. It had the words 'Forbidden' written on it. He then proceeded to take it to his office desk and laid it out on it. Dix followed him and sat down when he was invited to do so. Hiruzen handed him the scroll, opened at where the technique he needed was recorded. He also summoned a smaller scroll and picked up one of the pens from his desk and handed them both over to Dix.

"Here, you can copy the part and take it away. Keep it very safe, as this is an extremely strong and rare jutsu, so don't you dare come to me saying you lost it! Also if you ever manage to learn it or memorize it to the point you don't need the description anymore, burn it as soon as possible, so the technique doesn't get into wrong hands. Above all, this technique is forbidden for a reason. Make absolutely sure you are not in danger while you practice it. Do not try to rush it, your safety is way more important."

Dix listened to the Third's many advice attentively and memorized all of them. He can't take this lightly, as a major mistake could cost him dearly. He copied the technique fast, then handed the scroll back over to Hiruzen who stood up to put it back to its place. Just writing it down took almost 5 minutes, there were so many descriptions, depictions and warnings! The technique took up a good chunk of the forbidden scroll, and almost filled the entirety of the small one Dix was given.

"Naruto, you have to make absolutely sure that both you and the scroll are safe at all times! Don't cut corners and do your best. I believe in you." Hiruzen said as he returned from the cabinet, while looking straight into Dix's eyes with a very serious face.

"Yes, Uncle Hiruzen, thank you, but also, don't worry. I will make sure to do as you said." came the answer in a respectful manner. At this Hiruzen nodded and cracked a small smile.

"Go on now. I know you are eager to begin studying the technique. Come back regularly to tell me how you progress. Good luck, Naruto!"

"Thank you, Uncle Hiruzen! I will be going now..." he said and left the door, and soon the building. Hiruzen just sat back into his chair and leaned back with a dreamy face. He couldn't wait to see how far that young one will be able to go.

Dix rushed back to his house, as it was getting quite late, so he didn't go out to the woods just yet. He entered his house, threw his boots off, then quickly sat down to his table so he can start learning the technique as fast as possible. As said, it was really long, and even though he could've memorized it all, he didn't trust himself enough to flawlessly remember everything, so he intended to keep the scroll.

The technique wasn't only a long read though, but it was a monstrous task to actually learn and execute. The major steps are few in number, but the actual way of getting them to work are really hard and complicated.

The first thing to understand is that this is a space-time ninjutsu, meaning its quite unconventional compared to any other jutsu. These techniques tap into other dimensions to use as a means of transportation. And getting to other dimensions is simply... hard. Dix will have to feel things with his chakra that isn't really there. Or something like that.

Dix first thought he will be able to use Minato's advancements in this matter, for example his formulas, but there is a strange rule that is at work with these dimensions. Every person has their own dimension or set of dimensions their chakra is attuned with. Its also theorized that when someone first uses their space-time jutsu a new dimension is created to accommodate the breach in space and will stay there for the user to keep, but nobody actually knows. Everyone's chakra moves easier towards their specific dimensions, while trying to access someone else's is way harder. Obviously its possible, but its something monsters like the real Madara can do, and not many others. All this concludes that Dix has to start from scratch, doing his own research and finding his own dimension.
