If Uya hadn't known about forbidden Secret Technique like the Impure World Reincarnation and Flying Thunder God Technique, she might have actually been fooled into thinking that the Scroll of Seals was like this, and that these were the things recorded inside.
" Hiruzen Sarutobi, is this all the tricks you're playing?"
After shaking his head, Uya wasn't particularly disappointed, because Uya hadn't held out much hope to begin with. To be honest, Uya didn't value forbidden Secret Technique like the Reaper Death Seal or the Impure World Reincarnation much, as they weren't very useful to him.
If there's one thing Uya cares about most, it's probably the Flying Thunder God Technique.
However, the difficulty of mastering that technique is probably ridiculously high; otherwise, only the Second Hokage Tobirama Senju and the Fourth Hokage Minato Namikaze would be able to use it flexibly.
Continue turning the Scroll of Seals.
This time, Uya started from the beginning and carefully read through each page.
" Multiple Shadow Clone Technique, Eight Gates Released Formation, advanced applications of Chakra Flow "
As he flipped through the pages, Uya muttered to himself, because most of the techniques were ones he recognized and knew, and basically none of them were of much use to him.
Especially when Uya discovered that most of the techniques in this book were forbidden-level Genjutsu and barrier-type Ninjutsu, he really wanted to throw it directly at the face of the Third Hokage Hiruzen Sarutobi.
Damn, they have a good eye for talent!
With a slightly pained expression, Uya figured that Hiruzen Sarutobi must have put in a lot of effort to create this replica, probably carefully selecting it over a long period of time.
A hint of coldness gradually appeared in his eyes.
"In that case, don't blame me for copying the entire True Scroll of Seals one day."
Just as Uya was pondering how to obtain the true Scroll of Seals, the Scroll of Seals in front of him turned to its last page, causing Uya to suddenly show a hint of surprise.
Just as he was about to close the book and stop reading, he unexpectedly came across a page containing Secret Technique that interested him.
Spirit Transformation Technique!
In the original work, the Secret Technique used by Dan Katō allows his soul to leave his body, travel across distances to kill enemies, and even invade and control their mental world!
This technique bears some resemblance to the Mind Transfer Secret Technique of the Yamanaka Clan, but it is fundamentally different.
"Is it classified as Genjutsu control-type Secret Technique? But actually, it's not Genjutsu technique; it's a soul-based technique."
After carefully examining the technique from every angle, Uya narrowed his eyes slightly, revealing a thoughtful expression.
In the Hokage world, techniques are basically divided into three categories: Ninjutsu, Taijutsu, Genjutsu.
Techniques like the Impure World Reincarnation and the Reaper Death Seal fall under the category of Ninjutsu.
However, in Uya's view, these techniques cannot actually be considered simple Ninjutsu. Strictly speaking, they do not belong to Ninjutsu, Taijutsu, or even Genjutsu. Instead, they should be classified as a separate category: soul techniques.
Almost all techniques involving the soul are renowned, such as Shisui Uchiha's strongest Genjutsu, Kotoamatsukami, which can alter the consciousness of others. This undoubtedly cannot be categorized as Genjutsu, but rather as a soul technique.
Not to mention techniques like the Reaper Death Seal and the Impure World Reincarnation.
The Spirit Transformation Technique seems to be the foundation of techniques like Impure World Reincarnation and Reaper Death Seal Technique. With it, one can further study the soul and deduce techniques such as Impure World Reincarnation.
Even Orochimaru's Living Corpse Reincarnation Jutsu, which allows him to seize other people's bodies, is also a soul technique, derived from the Spirit Transformation Technique.
"Perhaps it's not so much that it's classified as Genjutsu, but rather that the technique is too basic and therefore not considered important, so it was placed here."
Uya murmured softly, still slightly puzzled that this technique had been left here. He guessed it hadn't received much attention from Hiruzen Sarutobi.
Or rather, Hiruzen Sarutobi felt that with Uya's power, this technique would be useless after Uya learned it, only good for killing or controlling people, and not as good as Uya's Quake Release.
But they underestimated this technique; it's the foundation of soul-based Secret Technique!
Among the techniques researched by the Second Hokage Tobirama Senju, the strongest are undoubtedly the Space-Time Ninjutsu Flying Thunder God and various soul-based Secret Technique.
"The soul is a realm that is almost impossible to reach under normal circumstances. The Second Hokage Tobirama Senju, was truly a genius. I wonder how long he researched it before he touched that realm and finally created those Soul Secret Technique."
After studying the Spirit Transformation Technique from beginning to end several times, Uya memorized it thoroughly before closing the replica of the Scroll of Seals.
Uya has always wanted to study the levels of touching the soul.
Because Uya's power can be said to be able to sweep and crush almost all Ninjutsu, Taijutsu, and Genjutsu. The only thing that poses a threat to Uya is soul-based techniques.
Both the Reaper Death Seal and the Kotoamatsukami are very threatening.
If Uya can achieve certain results in Soul Secret Technique, perhaps he can truly achieve perfection, complete perfection!
Moreover, after Uya opened the True Eight Gates Released Formation to the Fourth Gate, Uya vaguely sensed that the Seventh Gate and Eighth Gate in his mind might be opened in a completely different way than the previous ones.
They may involve the realm of the soul.
Three days later.
Inside the Hokage's office.
Uya returned the Scroll of Seals to the Third Hokage, Third Hokage kindly reached out and accepted it, asking Uya if he had learned any helpful techniques.
Uya didn't bother to expose him. In any case, Uya was already quite happy to have obtained the Spirit Transformation Technique. As for the Impure World Reincarnation and other techniques derived from the Spirit Transformation Technique, Uya wasn't interested in them. What Uya needed was just a foundation for a soul-based Secret Technique.
It can help him avoid detours and directly guide him to the foundation.
"It's just for reference. With my current strength, even forbidden techniques and Secret Technique can hardly improve me much. Besides, my Quake Release Kekkei Genkai is a special type of Kekkei Genkai, and all its power can only be developed by myself."
Uya casually said to Hiruzen Sarutobi.
Hearing Uya's words, Hiruzen Sarutobi's eyes flickered slightly, and a hint of regret appeared on his face. He said, "That's such a pity. If you had a special forbidden technique Secret Technique that matched what you've learned, perhaps you could have become even stronger and completely surpassed me, the Hokage."
Upon hearing Hiruzen Sarutobi's words, Uya's lips twitched slightly; he really wanted to smash that Scroll of Seals in Hiruzen's face.
However, now that he had learned the Spirit Transformation Technique, Uya couldn't be bothered to argue with Hiruzen Sarutobi.
To be honest, Hiruzen Sarutobi's true strength has always been a mystery. After gaining the Shockwave Sensing, Uya secretly observed Hiruzen Sarutobi last time, Uya felt that he should be much stronger than the Third Kazekage. To be continued.
