Fujin looked at his palm. The Flying Thunder God seal appeared on it. He extended his arm towards the door and touched it with his palm. In an instant, a mark of the Flying Thunder God seal was imprinted on the door.

Fujin's eyes glowed as he observed the seals on his door. A weird expression appeared on his face as he saw several dozen seals hidden on his door. Fujin wondered, '78 seals just on the backside of a door Exactly how many seals did I inscribe on my house? Five thousand? Ten Thousand? More?'

Fujin thought for a few seconds before giving up. Considering the crazy number of seals he inscribed, he hadn't bothered keeping a count. In fact, he couldn't even recall every seal he inscribed on the house. It was impossible for anyone to do so unless they had perfect memory.

He muttered to himself, 'Meh, it doesn't matter. The more, the merrier. If I don't know, then it is impossible for anyone else to know. Fortunately, I had the foresight to ensure that the seals could act autonomously to respond to various kinds of threats. Apart from a few seals that I would need to manage actively, the rest will respond by themselves. I'll let anyone stupid enough to attack this house figure out how many seals are here.'

Fujin focused his attention on the Flying Thunder God Seal. After a minute, he observed, 'This seal is slightly different from other seals. I can control it to change its position slightly.'

Under Fujin's control, the mark moved a few inches upwards on the door before stopping. Fujin analyzed, 'That said, it's the other factor that makes this seal very unique. Even though I am good at making seals, any Grandmaster can remove my seals given enough time. However, this seal is permanent. Unless I voluntarily remove this seal, it will stay forever.

Of course, it is possible that Tobirama and Minato know of ways to remove the seal but Hiruzen didn't include them in the scroll so that the method won't get leaked. It is also possible that Hiruzen and Danzo have come up with means to remove this seal considering that they had decades to study it.

Regardless, once I mark any enemy with this seal, that ninja will be as good as dead. Even if he is far stronger than me, I can just run away and keep sending Shadow Clones to kill him. Worse, I can have my clones prepare deadly jutsus before teleporting.

I can even send several clones at the same time. If the enemy still somehow survives, I can keep hiding and send Shadow Clones at random times to catch my enemy off guard. There is just no way to survive unless they can cut off the body part that was marked. Perhaps only someone as perverse as Obito might have a chance. Anyway, it's time to test it.'

Fujin disappeared from his spot and appeared at several spots inside his room. The last place he appeared in was the basement, where he sat down at the center and thought, 'I created 48 markings inside my house. Now time to see if I can sense them all.'

Fujin opened the scroll Hiruzen had given him and once again went through it. After a few minutes, he closed the scroll and sat in a meditative position.

Using the methods in the scroll, he tried applying the sensing technique mentioned in the scroll. Within an instant, Fujin sensed 48 markings! He could clearly feel the markings he had left inside his house.

Fujin's eyes snapped open. Shock could be seen within them. He wondered, 'What the hell? I sensed them on my first try? And I could sense all 48 markings so clearly?'

Fujin fell into deep thought. A couple of minutes later, he got up and left his house. He left 2 markings 50 meters from his house and another two at 100 meters before returning to his basement and trying to sense them. Once again, he managed to sense them without any effort.

He left his house and left more markings on trees at various distances from his house, the farthest being 2 kilometers from his house. Once again, he returned to his basement and tried sensing them. This time, he only managed to sense around half the markings.

Fujin opened his eyes and pondered, 'It looks like I can sense all the markings I make within a distance of 1.05 kilometers from me. Any farther and I can't sense them any longer. Still, this is nuts!

From the notes in the scroll, it is almost impossible to detect the markings on the first try. In fact, most who are considered 'talented' in space-time ninjutsu only manage to detect it after a few hundred tries. Only the likes of Minato and Tobirama probably sensed them more quickly. As for detecting up to 1-kilometer range That's even more absurd!'

Fujin stayed in his spot in disbelief for a few moments. Soon, a smile appeared on his face. He muttered, "Now this is an unexpected surprise! I never thought that my talent in Space-Time Ninjutsu would be this damn good!

At least in terms of sensing the markings, it is likely that my talent is better than both Minato and Tobirama. But..."

Fujin's mind suddenly became quiet. His expression became very serious. While he had always ignored an important aspect because he was too weak to do anything about it, his outrageous talent made him think. He couldn't help but wonder, 'Why is my talent in Space-Time Ninjutsu so absurd?

I'm not originally from this world and have transmigrated here. The body I transmigrated in didn't have any remarkable talent to speak of. Though my talent in the Wind element is very high too, it only became apparent after years of intense training. I couldn't be that lucky that the random body I transmigrated to not only had exceptional talent in Wind Manipulation but also had the best talent in Space-Time Ninjutsu, could I?

Or, is it because I have transmigrated here that I am talented in Space-Time Ninjutsu? After all, transmigrating in this world is far more advanced than merely teleporting from one place to another in this world. So, could the process of transmigration have given me remarkable talent in this aspect?'

Fujin let out a sigh and looked above. Though he was in his basement, the look in his eyes was as if he was seeing the vast space far beyond that world.

He questioned, 'Transmigration I was always very curious about how I transmigrated Is it just a law of nature? Does everyone do so? Or only some lucky souls get transmigrated? Or could there be some entity who transmigrated me here? If so, what is the purpose of doing that? After all, I was just an ordinary guy. What benefit would someone get from transmigrating me into what is most likely an alternate universe? Or is it just someone bored wanting some amusement?'

Fujin had several questions. Unfortunately, he would receive no answers. He shook his head and thought, 'Leave it. There is no way I can figure out this mystery as I am now. If I ever reach the level of Hagoromo, I can explore how Reincarnation works. After all, Hagoromo's sons have been reincarnating for centuries.

As for transmigration in a different universe, that should be way more advanced than that. I doubt even the strongest Otsutsuki has any knowledge of this. I can only keep getting stronger and hope that someday I am able to solve these mysteries.'

A smile appeared on Fujin's face as he thought, 'I just hope I don't end up dead before reaching such a level. Well, whatever, that's too far away. I first need to master the Flying Thunder God jutsu and take advantage of my knowledge to gain the most out of upcoming wars.

For now, I will have to spend some time increasing the range up to where I can detect the markings. From the notes, it seems like Tobirama's range wasn't very impressive. It was probably why he failed to escape.

However, Minato managed to increase his range to a ridiculous level. In the fourth Great Ninja War, he was able to teleport from the battlefield to Konoha while taking the Truth Seeking Balls with him.

I wonder if Sage mode helps in increasing the range. If I can mark several locations on the entire planet and sense them at will, then killing me would become impossible. After all, unlike Tobirama and Minato, I have no intention of sacrificing myself.

I will work on extending the range later. The 1-kilometer range is good enough. I'll directly begin working on the third step. It'll be wonderful if I can get it down in one try as well, hehehe.'
