'Spirit Transformation jutsu'

Fujin was sitting at the center of his basement. Around him were his Shadow Clones, silently working on a seal that had never appeared in the Ninja world. Fujin's mind was focused on his own soul completely. He made the necessary hand seals and used the jutsu Dan created decades ago.

Suddenly, a white light slowly exited his body. It immediately attracted the attention of every Shadow Clone in the basement, who looked at their main body. The white light quickly took form and took Fujin's appearance.

Fujin observed himself while thinking, 'Hmm, interesting. My form is just like that of my body. There isn't even a hint of my previous life's appearance. In addition, even my soul has similar clothes as my main body, even though it's just my soul taking that form and not actual clothes.

I wonder how the soul works Does it just take the form of whatever body I am currently occupying? If so, how will it work for someone like Orochimaru who keeps changing his body? Does his soul's appearance keep changing every few years? Or has only my soul changed due to getting transmigrated? After all, how can I know what changes my soul underwent during transmigration? Sigh, so many new questions again'

Fujin stopped thinking about those questions and instead focused on his soul. He thought, 'Anyway, time to test what all this technique can do. Now, who do I choose as a test subject?'

Fujin's first thought was one of the orphan kids. However, on second thought, he decided against it. If something went wrong, then the one he chose be crippled or worse, dead.

Fujin thought, 'Normally, I'd go out and choose some bandits. I have been training this jutsu for almost a couple of months, so it won't raise any eyebrows if I head out as it has been several months since my last trip. However, this technique isn't like others. I could test something like the Eight Trigrams Divination Seal without any worry.

Unfortunately, Spirit Transformation jutsu has a huge chance of something going wrong. I should test it inside the village, where I can ask for Hiruzen's help quickly. Oh well, it's not like there aren't any test subjects here. That said, let me at least test the movements and other basic skills first.'

The most basic abilities of this form were invisibility and intangibility. Both were mentioned in the scroll. Fujin applied the techniques and his soul became invisible. He chuckled and wondered, 'It works. I don't understand why Jiraiya never learnt this jutsu! It's the perfect jutsu for his 'research'. I wonder if Tsunade and Hiruzen predicted that and decided to never give him that scroll. Hmm, that should be it. Otherwise, I don't see any reason for Jiraiya to not learn this jutsu.'

Fujin moved towards the ceiling of the basement and thought, 'Though I didn't know this jutsu earlier, some of my seals are effective against this jutsu. So, no spirit should be able to move in and out of my house. At least not with this technique.'

Fujin touched the ceiling. As he expected, his hand couldn't phase through. He deactivated the seals that stopped the Spirits temporarily and phased through the ceiling. He quickly phased through his house and began flying above his house.

A smile formed on his face as he thought, 'Hmm, not bad at all. This feeling is great. Other than a few seals and barriers, nothing can stop me. I can even fly in this form. Not to mention, my Flying speed is amazing!'

Fujin immediately flew around the village, while avoiding the sensitive places. No one could see his spirit. What was more impressive was the speed at which his soul could fly! It exceeded the speed of sound by several times!

Fujin thought, 'Such an incredible speed. It might even exceed Raikage's speed. And, unlike Raikage's speed, I have a feeling that I can sustain this speed for days. Only Flying Thunder God is faster as it is nearly instantaneous. Tsk, no wonder Dan could dream about the Hokage's seat. Though I don't think he was as strong as Sakumo or the Sannins, this technique is incredibly fearsome. Even the Third Raikage and Onoki would have been extremely wary of this jutsu. His lethality might have been just under that of Minato's lethality in the Third Great Ninja War.'

Having explored the speed and the intangibility, Fujin's soul returned to his body. The Shadow Clones sighed in relief seeing that nothing bad happened. Fujin got up and said, "That's enough training for the day. Unless you're close to some sort of breakthrough, dispel yourselves."

The seal Fujin was working on was extremely complicated. He didn't want to take the risk of forcefully dispelling a clone that might have a breakthrough and advance the seal further. Hearing his words, all but three of his Shadow Clones dispelled themselves. Fujin collated their memories before leaving his house. He went directly to Konoha's Torture and Interrogation department.

Ibiki was pleasantly surprised to see Fujin until he recalled the scenes when Fujin had visited him the previous time. He thought, 'Fortunately he isn't carrying a prisoner. If he did, I'd have directly diverted him towards the prisons. I don't want my office to stink of vomit and shit!'

Fujin was unaware of Ibiki's thoughts. He hadn't ever even thought about Mizuki after handing him to Ibiki. He warmly greeted, "Ibiki-san, how have you been?"

Ibiki smiled and said, "Have been well. How about you? To what do I owe the pleasure of your visit?"

Fujin replied, "Doing great as well. As for my visit, I wanted to borrow some of your prisoners to test a new jutsu I have been learning."

Ibiki was surprised. Though he would get such requests occasionally, they would be very rare. He asked, "To what degree the injuries could be? And, what would be the chances?"

Fujin replied casually, "If everything goes well, then there won't be any injury. If things don't go well, then that person would be crippled in the best case, dead in the worst case. I'd prefer a normal human though."

Ibiki thought a bit and said, "Alright. I have a prisoner who was arrested for raping a minor and is supposed to be executed in a few days. You can test your technique out on him. Knowing his past, feel free to cripple him further even if everything goes well."

Fujin nodded. Ibiki called a subordinate and asked him to lead Fujin to that prisoner's prison. Ibiki's subordinate led Fujin to the prison and allowed him to enter, leaving him alone with the prisoner.

The prisoner was a middle-aged man and in terrible shape. Fujin could see several scars all over his body. Several of his nails were missing. Instead, some of his fingers had 'nails' nailed in them instead of actual nails. His face was entirely swollen.

The man looked at Fujin. Terror was visible in his eyes. Yet, there was also resignation. He said, "Get on with it. You motherfuckers can't torture me anymore!"

Fujin chuckled and said, "As an ordinary human, you shouldn't try to estimate what a ninja can or cannot do."

Several Shadow Clones appeared around Fujin. Fujin sat on the ground and weaved hand seals.

'Spirit Transformation jutsu'

Fujin's soul exited his body. The prisoner watched with confusion as he didn't understand why his 'torturer' had begun meditating. He wondered, 'Is this some new style of torture?'

Suddenly, his eyes widened as he instinctively felt something enter his body. He felt a chill and fear like never before. Yet, he didn't understand what was happening!

What his eyes couldn't see was that Fujin's soul had already entered his body! Meanwhile, Fujin could clearly see the man's soul. He extended his arm towards the man's soul. Remembering the steps in the scroll, he began using his energy to affect the man's soul. Within a few seconds, his soul fell under Fujin's control.

Fujin analyzed, 'Hmm, not bad. By controlling his soul, I can control his entire body. Of course, it is this easy because his soul is too weak and has almost no willpower. A rank S ninja's soul will have tremendous willpower. I might not be able to control it so easily.

Even more troublesome would be someone who actually trained or strengthened his soul or knows how to use his soul. I shouldn't rely on this technique against Orochimaru. Similarly, I can't use it against a Rinnegan wielder. I am not too sure about Obito and Zetsu either. Who knows what additional techniques they know? Oh well, time to test it.'

Fujin quickly took control of the prisoner's body and said in a calm voice, "Release his restraints."

One of the clones nodded and removed all the chains and cuffs. Fujin stretched the prisoner's body while analyzing, 'Hmm, my control isn't very smooth. It's more like controlling a puppet. However, I have a feeling that the Yamanaka's Secret Technique is better at controlling others than this jutsu. That said, this jutsu has other specialities which the Yamanaka technique can't match.'

Acting on his thoughts, Fujin began suppressing the prisoner's soul. The prisoner, who had lost control of his body, suddenly felt a pain like never before. A soul-wrenching scream exited his throat! If not for the silence seals in the prison, the entire T&I Department would have heard his scream!
