Fujin stared at a seal in front of him. It was created by the Shadow Clone who dispelled himself and sent everyone the memories. A smile appeared on his face as he thought, 'The curse seal is finally complete!'
The curse seal was shaped like a windmill, with several symbols in it. Fujin thought, 'Though I hadn't seen either of the seals before, studying it wasn't difficult as they were made of familiar symbols. The difficult part was learning how Danzo could create an imprint to ensure that others couldn't remove his seals. Fortunately, I managed to get a hang of it a week ago. I guess that's another reason to be thankful to Danzo, hehe.'
Danzo's help allowed Fujin to raise his Wind Vacuum Technique to a whole new level. And now, he had also helped Fujin improve his Juinjutsu.
Fujin's smile faded as he thought, 'Unfortunately, while I can apply the curse seal at will, I can't apply my imprint at will. I can only do so if the one I'm planting the curse seal on doesn't resist. If there wasn't this flaw, then Fuinjutsu Grandmasters would have been the strongest ninjas in the elemental nations. It'd be stronger than any Kekkei Genkai. In fact, I doubt even the Mangekyou would be comparable to this ability.
Fortunately, I don't need to inform the target about the abilities of this seal. As long as I have his or her consent and they don't resist, I can apply it to them. So it shouldn't be an issue for me to apply it to my subordinates. Not to mention, I can also add it to seals I place in any bases I create in the future. It'll increase their defenses considerably.
Anyway, coming back to the seal, it has all the functions of Danzo's two seals in addition to a few more functions that I added. I also changed the structure and used a different method to construct them so that no one would be able to connect those two seals to each other. Of course, without anyone constraining me, my seal is far more powerful than what Danzo uses on the Root ninjas!'
Unlike Danzo, Fujin didn't intend to use two different seals. Instead, he had merged the two seals into one, but the seal was still made of two different parts.
The first part was similar to the Cursed Tongue Eradication Seal. It would detect whether the ninja had any thoughts of divulging secrets of the organization. If the ninja ever tried to put those thoughts into action, the seal would activate and paralyze him.
The only difference was that, unlike Danzo, it would alert Fujin that the seal was activated. In addition, it would also allow him to locate the position where the seal was. Of course, it wasn't a godly ability and was instead an application of the Flying Thunder God mark. As such, Fujin could only locate the position if it was within the range Fujin could detect it.
During the 3 months of training, Fujin's range of detection had increased from 15 kilometers to 80 kilometers. His Space-Time Sensing Technique's range had also increased from 4.5 kilometers to 12 kilometers. As such, it was far superior to Fujin's chakra field. Regardless, for the time being, Fujin wouldn't be able to detect the location of the seal if it went off in the Land of Rivers while he was in Konoha.
Once the seal was activated, the paralyzed person would stay paralyzed until Fujin decided to stop it or if another Grandmaster or someone who knew how to stop it helped him out. Of course, even if the Grandmaster helped him, the seal would reform, not allowing any information to be leaked.
The second part was even more strengthened. Unlike Danzo's seal, which was activated only when it detected foreign Yin chakra, Fujin added another feature. Not only would it activate when a foreign Yin Chakra tries to infiltrate the brain, but it would also activate if a Grandmaster tried to remove the first part of the seal.
While the seal couldn't be removed thanks to Fujin's imprint, Fujin had left a small portion of the seal unprotected by his imprint. It was still extremely complicated, implying that only a Fuinjutsu Grandmaster could successfully remove it. As soon as that portion of the seal was destroyed, the second part of the seal would attack the Grandmaster in a similar way Fujin was attacked when he tried reading the memories of the Root ninja he killed. In addition, it would also transfer a Flying Thunder God mark onto that person, allowing me to hunt down that person later on.
On the other hand, if someone tried reading his memories, the effect would be very similar. The enemy will be attacked while the seal will destroy the brain of the one who bears this seal, killing him or her in the process.
However, there were two big differences. The first one was that the second seal also contained Fujin's Flying Thunder God mark! As such, he would be able to teleport to every ninja who had this seal once his range increased.
And secondly, enemy Yin chakra wasn't the only condition to activate the seal, killing the ninja in the process. Fujin could activate the seal at will! The life of every person in his organization would be in Fujin's hands!
If Danzo could have his way, he would have added this ability to the seals as well. Unfortunately for him, even though he had full control over the Root, he still had to adhere to certain limits. Hiruzen watched over his actions. Creating such a seal was something Hiruzen would never allow. Even if Hiruzen allowed it, as long as others learnt of it, every clan in Konoha would have been in an open rebellion. Either the two of them would have been overthrown or the village would have collapsed.
Luckily for Fujin, he didn't have any such constraints. Unless one of his subordinates became a Grandmaster in Fuinjutsu, they wouldn't even be aware of the fact that Fujin could kill them with a thought.
Of course, Fujin had no intention of being a tyrant like Danzo or Orochimaru. He had only added that ability to take out any spies or traitors. He didn't intend to force the members to do something that went completely against their will.
There was another major difference between Fujin's and Danzo's seals. Danzo's Cursed Tongue Eradication Seal was visible on the tongues of Root ninjas while his other seal was hidden. In the case of Fujin's seal, both parts of his seal were hidden.
As such, an enemy was extremely unlikely to discover the seal before the first part was activated. The second part was even more difficult to detect as it was further hidden by the first part of the seal. Unless someone managed to remove a part of the seal, it wasn't possible to understand what was hidden.
However, if someone managed to do so, they would activate the second part of the seal, making it impossible to study it. Not to mention, the seal had Fujin's imprint. So only the part of the seal that Fujin had purposefully not protected by the imprint could be removed and it wouldn't be sufficient for anyone to study the second part of the seal.
In all, it was quite an effective and disgusting seal. It was an extremely effective seal for ensuring discipline and maintaining control in an organization. And, it was disgusting for anyone trying to undo the seal. It was filled with several traps. Once Fujin's Flying Thunder God's range improved, he could directly send Shadow Clones who had prepared rank S jutsus to the location of the seal and destroy anyone who had captured his subordinates and was trying to undo the seal.
Fujin was extremely pleased with the seal. He had worked quite hard to cover all aspects he wanted to. He spent a couple of hours making an imprint of the new seal. He looked at his left palm where the new seal imprint was created and thought, 'This seal… I'll call it the Phantom Seal. It will be the sign of every member of my organization. It will also go well with the name I have thought of.'
Fujin smiled and muttered, "The name of my alliance will be…"
