In his basement, Fujin and several Shadow Clones were sitting in a meditative position. Each one of them faced a pillar or the walls which had one Flying Thunder God seal marking on them. Fujin's body was tired from opening the Gate of Opening and trying to open the Gate of Healing. As such, he and his shadow clones focused on the Flying Thunder God technique. Despite having felt that a breakthrough was close, the breakthrough eluded Fujin for a month!

As they meditated, one Shadow Clone suddenly felt a change. He kept his eyes closed and focused entirely on the seal in front of him.

In a few seconds, some chakra disappeared from his body. Almost instantly, a small portion of the chakra that had disappeared from his body appeared on the Flying Thunder God Seal in front of him. A glee appeared on his face as he thought, 'I see, so this is how space-time travel happens'

The clone closed his eyes and recalled how the process happened. He thought, 'When the chakra exited my body, it entered a different dimension. It was able to somehow move through it because I could sense the marking in front of me. This is exactly what is mentioned in the scroll.

The scroll stated that after Tobirama wasn't satisfied with just using Reverse Summoning for Flying Thunder God, he kept researching more about Space-Time Ninjutsu. However, it was mostly a dead-end. Only after finding this dimension, did Tobirama make a breakthrough and create a true teleportation technique that is usable in battle. The scroll says that Tobirama named this as Dimensional Void.

But What is this dimension? The scroll doesn't mention how Tobirama found or even sensed this dimension. It doesn't even say anything about what this dimension is. It only says that the dimension can only be accessed with the Flying Thunder God Seal and that travelling through it isn't completely safe.'

The clone thought for a few minutes before letting out a sigh. He muttered to himself, 'This world is still so full of mysteries. Even someone like Hiruzen is unaware of the fact that all the chakra we use originated from Kaguya. And she is from a crazy strong clan. Who knows what mysteries are involved with the Otsutsuki clan? And that is just the start. How many such mysteries exist in this universe?

Even just restricting myself to this planet, there is so much that no one knows. Why are there so many chakra-rich resources in this world? Do resources like those exist on every planet or is this planet special for some reason? What is this dimension that can be used for space-time travel? What is the extent of this dimension? Does it only cover this planet or does it cover the entire universe? Why do some symbols coming together form a unique power that allows us to access this dimension?

Even though I have become a Grandmaster in Fuinjutsu, I still don't understand why these symbols have such power. I don't think anyone else does as well. Sigh, so many mysteries. I wonder if I will ever get to the bottom of this Anyway, time to test it.'

The clone raised his left hand slightly and brought it to his chest height. The Flying Thunder God seal appeared on his palm. Soon, a Wind Explosion Sphere formed on top of his left palm.

The chakra fluctuations due to creating a jutsu were sensed by everyone in the basement. Immediately, Fujin and all his clones spanned out of their meditative states and observed the clone who was creating the jutsu. All couldn't help but wonder, 'Did he complete the first part of this third step?'

Despite wondering that, no one disturbed the Shadow Clone. The clone, who had formed the Wind Explosion Sphere, had his entire attention focused on it. In front of everyone's gazes, the Wind Explosion Sphere disappeared!

Everyone's eyes widened. The jutsu hadn't dissipated. Instead, it had disappeared from the room. The Wind Explosion Sphere appeared in the Dimensional Void. However, before the clone could make it appear at the Flying Thunder God Seal in front of him, the jutsu dissipated in the Dimensional Void. Nothing reached the seal in front of him.

A frown formed on the face of the clone as he analyzed, 'The warnings were true. Even though I can now sense the Dimensional Void, moving through it is still very difficult. Wind Explosion Sphere is a very unstable jutsu and uses very little chakra. I need something more solid'

The clone focused on his left palm again. He released the chakra and it began rotating rapidly. Soon, a Rasengan formed in his left hand. Just like the Wind Explosion Sphere, the Rasengan disappeared from the basement as well. It appeared in the Dimensional Void.

The clone immediately sensed the Flying Thunder God Seal in front of him and had the Rasengan move towards it. Unfortunately, the Rasengan began crumbling as well. Only some chakra made it through and hit the pillar in front of him, causing a small explosion.

The eyes of everyone in the room glittered. The clone had indeed had a breakthrough. However, the clone wasn't satisfied. He analyzed, 'It looks like this will require a lot of practice as well. The second part of this third step, huh? That said, I'm interested in seeing what this Dimensional Void is and how things move through it. Experiencing it will make completing this step a bit easier.'

He closed his eyes again and focused on himself. A second later, he disappeared from the basement. Once again, no one in the basement could sense where he went.

The clone appeared in the Dimensional Void and opened his eyes. His eyes widened in shock as he realized, 'What an intense pressure! My body can't move an inch! How can I even move in this dimension?'

The clone was confused. The pressure was too intense. Even if he became stronger in the future, he didn't see himself being able to move around in the Dimensional Void.

The clone immediately unleashed most of his chakra to resist the pressure. Unfortunately, it wasn't much help. He still couldn't move. However, his eyes moved rapidly trying to absorb any information he could. At the same time, his mind tried to sense the seal markings he had created.

Immediately, the clone noticed two things. The first was the dimension itself. There was nothing in the dimension at all! Even light wasn't present there! The clone couldn't see anything. However, as a ninja, light wasn't something he relied on entirely. His eyes glowed and he focused chakra on his ears and nose as well. However, he still couldn't see, hear or smell anything.

He thought, 'No wonder Tobirama named this as the Dimensional Void. There is nothing here. Or at least, there is nothing here that a rank S ninja is capable of sensing.

That said, this is indeed a surprise. I thought that we would have to move through this dimension in order to be able to teleport in the Naruto world. I assumed that either I would be able to travel in this dimension at the speed of light, allowing me to move like I am teleporting, or the speed at which time flows in this world would be far faster, creating a similar effect.

However, I can't even move my body in this dimension. Instead, I can clearly sense all the markings that are within 1.05 kilometer range from the place I was sitting at. I just have to decide which marking to select and I can teleport there at will Or rather, I will be able to do so in the future.

In other words, these markings act as portals. Or rather, the seal on my body and any marking I choose come together and act as a portal using this dimension as the medium, allowing me to teleport. Hmm, can this be called teleportation? Tough to say. Regardless, the effect is indeed similar.'

The clone focused his mind on the marking on the pillar in front of him and tried leaving the Dimensional Void through it. Unfortunately, he couldn't do so. Finally, his body couldn't handle the intense pressure and he was dispelled.

Though the clone had experienced a lot, he didn't actually spend a lot of time in it. He was in the Dimensional Void for less than a second! As soon as he was dispelled, his memories were transferred to Fujin and the remaining Shadow Clones.
