Fujin felt that his speculation was on point. His mind quickly began calculating how he could learn that level of Juinjutsu. His eyes landed on the dead body in front of him as he thought, 'One way will be to study this dead body properly.
I need to understand what biological changes Zankoku experienced after undergoing the ritual. I will need to compare his body to a normal body and experiment to understand which seals could cause such a change. That could form a base for me to understand how a Juinjutsu of this level could be created.
To reach that stage, I will first have to properly study and research this dead body. Unfortunately, I have zero expertise in this field… To be able to do that, I will need to take up Yoshi's offer and pursue Medical Ninjutsu. But…'
Fujin had a headache. He was already learning a lot. He specialized in Ninjutsu and had mastered well over 50 jutsus. While his main focus was on the Wind element, he had also learnt several powerful ninjutsu of Lightning, Fire and Earth elements. In addition, he was also working on Space-Time Ninjutsu, which was entirely different from any other Ninjutsu.
Though Ninjutsu was his speciality, he had diversified his skills a lot already. In terms of Fuinjutsu, he was already at the highest rank in the ninja world. Considering the speed of his progress, very few would be able to claim to be as good as him at Fuinjutsu after a few years.
His Taijutsu was extremely strong as well. Not only did he know two of the strongest fighting styles, he also knew the forbidden Eight Inner Gates formation and he could open two Inner Gates. That alone made him one of the strongest Taijutsu users in the Ninja world.
While his Genjutsu wasn't as spectacular as the other three fields, Fujin was still better than any Special Jounin who specialized in that field. More importantly, he had developed the skills to counter the Sharingan and was extremely good at detecting and breaking Genjutsu.
If Fujin worked on Medical Ninjutsu, then it would take a lot of his time and energy. Even with Shadow Clones, it won't be an easy task.
Fujin sighed at the thought of increasing his already ridiculous workload. He decided, 'I have no choice… It looks like I have to work on this aspect. Even if not today, I might need this skill sometime in the future. In fact, I have a feeling that I'll be needing these skills a lot in the future.
That said, researching dead bodies isn't an easy task. Though I came from a technologically advanced world, I never focused on improving my medical knowledge. So I won't have any advantage over others in this world despite the advances in my previous world.
Not to mention, being able to research something as complicated as Zankoku's body can probably be done by only a handful of ninjas. The only ones that come to mind are Tsunade, Orochimaru and maybe Kabuto and Sasori. The process of studying his body will be far more efficient if I can get the help of one of them. However, how can I get their help?'
While Fujin's analysis was logical, he had no method of cooperating with either of those four or anyone else who was very good at this aspect. He thought enviously, 'To have a subordinate like Kabuto… That bastard is extremely lucky. Maybe I should focus on raising ninjas that can assist me in this regard.
Hmm, yeah. That will be the best. If I can raise or recruit someone who is very good at Medical Ninjutsu and researching, then my work will be simplified. After all, it is unrealistic to assume that I can reach the top in every field. If I hit a limit, then all my plans related to this would have to be dropped. If I can raise someone talented at this, I will only need to improve my medical knowledge sufficiently to ensure that I don't get tricked.
I will begin working closely with Yoshi after I master the Flying Thunder God and make a curse seal. Once my expertise in Medical Ninjutsu improves and I get help from someone capable, I can begin researching the changes the Ritual and the seals brought to his body.
However, this will be a long-term plan. There is actually another way for me to learn more about this level of Juinjutsu. That way is Hidan!'
Fujin stored Zankoku's body back in the scroll. He removed all the traces he left in the cave, left the cave and began moving back to Konoha.
En route, he analyzed, 'If a Bishop is indeed needed to perform the sacrificial ritual, then a Bishop should already be in touch with Hidan. I need to find that Bishop and read his memories. If his strength is the same as Ketsueki's, then it wouldn't be a problem for me to neutralize him.
His memories should clear all my doubts. I might even understand the high-level Juinjutsu that the Bishops use. That said, I don't think that he would know the ritual to become able to manipulate blood.
After all, Hidan didn't have that ability. His ability was immortality. I wonder if the Bishop sucked out the Life Force from ordinary people or something like that… Regardless, Hidan's ability is even more broken. I won't complain if I can gain that.
Even if he doesn't have the information, as long as I can find the location of that secret Jashin sect or cult, I will achieve my goal. Once I master the Flying Thunder God, I'll directly attack them and read their memories one member at a time.
As a society that has been hiding for a long time and has such a high level of Juinjutsu, its strength should be quite high. But since they don't dare to expose themselves, it implies that their strength is far weaker than the Five Great Villages. As long as I watch out for any Juinjutsu traps, they shouldn't be able to stop me. And considering their mysterious means, the knowledge they have might be as good or even better than what the Uzumaki clan had.
Reading his mind will also allow me to understand whether there really is a Jashin who speaks with them or if it is just some scheme they are running to achieve some goal.
The only issue with this plan is that capturing and reading the memories of that Bishop can affect Hidan's ritual. If it doesn't go through, then Akatsuki's structure might undergo some changes. However, even if it causes some changes to the future I know, the benefits of doing so are too high. Akatsuki's goals won't change even if Hidan doesn't join them while my strength will grow several folds due to doing this.
I will do it now. I'll return to the village and take some elimination missions in the Land of Hot Water. Once I find Hidan and the Priest, I will find my answers!'
Fujin returned to the village at a high speed, resting just once during the night. While he rested during the night, Fujin had a thought and his expression became very peculiar. He thought, 'In my previous life, whenever I read about someone working with dead bodies, I would always feel very weird and get a creepy feeling due to the nature of the job.
It was even more so in anime when I read about characters like Danzo, Orochimaru and Kabuto experimenting with them. However, I unknowingly spent the last few days studying a head that I cut off and a dead body I have been storing for over 3 years! When did I become like this?'
Fujin was left speechless by the realization. While the excessive amount of killing he did in this world meant that he no longer felt any stigma while inspecting the dead bodies, he never thought that someday he would become so focused on studying dead bodies and even plan on improving his medical knowledge to do that better!
Fujin just shook his head and thought, 'I doubt the me who had just arrived in this world would be able to connect with the present me. Oh well, nothing I can do about it. Surprisingly, it isn't that hard to get used to being around dead bodies.'
Fujin began resting for the night and continued his journey the next day. In Konoha, Hiruzen was working in his office when he received a high-priority scroll from the Daimyo of the Land of Hot Water.
As Hiruzen read the details in the scroll, a frown appeared on his face. He thought, 'I expected them to face troubles in becoming a peaceful country, but this is just too much. No wonder the Damiyo is panicking so much. Still, this resembles a lot with that particular mission...'
Hiruzen thought for a bit and instructed, "Takao, call Fujin to my office."
