If Naito hadn't known about the forbidden arts such as reincarnation and flying thunder god created by the Second Hokage Senju Tobirama, he might have been deceived into thinking that this is what the Sealed Book looks like and that this is what is recorded in it. .
"Sarutobi Hiruzen, is this a trick?"
After shaking his head, Yu Ye was not particularly disappointed, because Yu Ye didn't have much hope in the first place. Speaking of which, Yu Ye didn't attach much importance to the forbidden techniques such as the sealing of corpses and the reincarnation of dirty soil. For him, The effect is not too great.
If Yu Ye cares more about it, it's probably Fei Lei Shen.
But the training difficulty of that thing is estimated to be ridiculously high, otherwise only the second generation Hokage Senju Tobirama and the fourth generation Hokage Namikaze Shuito would not be able to use it flexibly.
Continue to turn the pages of the sealed book.
This time, Yu Ye started from the beginning and read page by page carefully.
"The art of multiple shadow clones, the eight-door armor, the advanced application of chakra flow..."
As he flipped through the pages, Yu Ye murmured to himself, because most of them were techniques he knew and knew, and basically they didn't have much effect on him.
Especially when Naito discovered that this book actually contained more than half of the forbidden magic-level illusions and barrier-type ninjutsu, he wanted to throw it directly into the face of the third Hokage Sarutobi Hiruzen.
Really good at choosing!
With a slightly pained expression, Naito felt that Hiruzen Sarutobi must have put a lot of effort into making this imitation, and he must have chosen it deliberately for a long time.
A hint of coldness gradually appeared in his eyes.
"In that case, don't blame me for taking the real sealed book and copying it all."
When he was thinking about how to get the real book of seals, the book of seals in front of Yu Ye turned to the last page, and Yu Ye suddenly showed a look of surprise.
Just when he was about to close it and stop reading, he unexpectedly saw a page of secret techniques that interested him more.
The art of spiritualization!
The secret technique used by Kato Dan in the original work can make his soul leave his body, travel and kill enemies regardless of distance, and even invade the enemy's spiritual world and control them!
This move sounds very similar to the secret technique of turning the heart of the Yamazaka clan, but it is fundamentally different.
"Do you attribute it to the secret art of illusion control? But in fact, this is not an illusion, but... a soul-type art."
After carefully reading this technique bit by bit, Yu Ye narrowed his eyes slightly and showed a thoughtful expression.
In the world of Naruto, tricks are basically divided into three categories: ninjutsu, taijutsu, and genjutsu.
Techniques such as reincarnation in the dirt and sealing away ghosts all fall into the category of ninjutsu.
But in Yu Ye's view, these techniques cannot actually be regarded as pure ninjutsu. Strictly speaking, they are not a type of ninjutsu, physical technique or even illusion, but should be another separate category, the technique of the soul.
Almost all techniques involving the soul are famous. For example, Uchiha Shisui's strongest illusion technique, Betenjin, can change the consciousness of others. There is no doubt that this can hardly be classified as an illusion technique, but a soul technique. .
Not to mention the sealing away of corpses and reincarnation in the filthy soil.
The art of spiritualization seems to be the basis for the techniques of filthy earth reincarnation and corpse sealing. With it, we can further study the soul and deduce filthy earth reincarnation and other techniques.
Even Orochimaru's undead reincarnation, which can seize other people's bodies, is also a soul technique, and it is also extended from the spiritual technique.
"Perhaps it's not that it's attributed to illusion, but that it's too basic and doesn't seem that important, so it's put here."
Naito murmured softly, still a little surprised that this technique was left here, probably because it didn't get much attention from Hiruzen Sarutobi.
In other words, Sarutobi Hiruzen felt that with Yu Ye's strength, this technique would be useless after Yu Ye learned it. It could be used for killing people and controlling things, and it was not as good as Yu Ye's Zhendun.
But they underestimated this technique too much. This is the basis of soul-like secret techniques!
Among the techniques studied by the Second Hokage Senju Tobirama, the strongest ones are the space-time ninjutsu Flying Thunder God and various soul-based secret techniques.
"The soul is a field that is almost difficult to enter under normal circumstances. The second generation Hokage Senju Tobirama is really a genius. I don't know how long he studied it before he came into contact with that field, and finally created those soul secret techniques."
After studying the art of spiritual transformation several times from beginning to end, Yu Ye kept it in mind before closing the imitation book of seals.
Yu Ye has always wanted to study the level of touching the soul.
Because Yu Ye's power can be said to be that he can sweep through almost all Ninjutsu, Taijutsu, and Illusion techniques. The only thing that poses a threat to Yu Ye is soul-based techniques.
Whether it is the corpse ghost seal or other gods, they are all threats.
If Yu Ye can achieve certain results in the soul secret technique, maybe he can truly achieve perfection, complete perfection!
Moreover, as Yu Ye opened the True Eight Gate Dunjia to the fourth gate, Yu Ye could faintly feel that the seventh and eighth gates at the end in the brain were probably opened in completely different ways from the previous ones.
They may involve the realm of the soul.
…
Three days later.
In the Hokage's office.
Naito returned the imitated Book of Sealing to the Third Hokage, who took it with a kind expression and asked Naito if he had learned any helpful techniques.
Yu Ye didn't bother to expose it. Anyway, Yu Ye was quite happy to have obtained the art of spiritual transformation. As for the techniques such as the reincarnation of dirty earth extended by the art of spiritual transformation, Yu Ye was not interested. All Yu Ye needed was a soul. The basis of quasi-occult magic.
A foundation that allows him to avoid detours and guide him directly to the past.
"Just for reference. For my current strength, even forbidden arts, secret techniques, etc., can hardly improve me much. Besides, my Shock Escape Blood Succession Limit is originally a special type of Blood Succession Limit. Everything Strength can only be developed by yourself.”
Naito said casually to Sarutobi Hiruzen.
Listening to Yu Ye's words, Sarutobi Hiruzen's eyes flickered slightly, but there was a trace of regret on his face, and he said: "That's such a pity. If there is a special forbidden secret technique that corresponds to what you have learned, maybe you can Let you become stronger and completely surpass me, the Hokage."
In response to Sarutobi Hiruzen's words, the corners of Naitobi's mouth twitched slightly, wanting to slam the imitation Book of Sealings on his face.
But now that he has learned the art of spiritual transformation, Naito is too lazy to argue with Sarutobi Hiruzen.
Speaking of which, the true strength of Sarutobi Hiruzen has indeed always been a mystery. After Yu Ye had a shock wave sensor, he secretly observed Sarutobi Hiruzen last time. Yu Ye felt that he should be much stronger than the Third Kazekage.
