Starting with the Uchiha clan, they began cultivating demonic arts.

Chapter 66 Choosing Ninjutsu

Uchiha Touyu didn't quite believe what the Third Hokage said, but he didn't say anything. Instead, he opened the Book of Seals, which had been mostly unsealed, and began to examine it carefully.

However, even after the seal was broken, the contents of the Book of Seals were completely incomprehensible to Uchiha Touyu. Apart from the description of the ninjutsu below its name, the rest was all gibberish.

Uchiha Touyu looked up, his face blank with confusion. The Third Hokage chuckled and said calmly:

"After all, ninja techniques are incredibly diverse. Even the Sharingan of the Uchiha clan has the ability to copy memories. To ensure safety, all ninjutsu content is written in code. You can choose the ninjutsu you need from the descriptions, and then I will hand you the codebook for decoding."

Upon hearing this, Uchiha Touyu nodded slightly, inwardly sighing:

Putting aside other aspects, the ninjas did indeed excel in intelligence gathering; normally, the contents of the Book of Seals would almost never leak out.

Of course... no matter how normal the operation, it can't beat internal treachery. People like Uchiha Madara and Orochimaru, who were once considered the successors to the Hokage in Konoha, defected for various reasons, and naturally, some of the contents of the Book of Seals were leaked out.

This thought flashed through Uchiha Touyu's mind, and then he lowered his head and began to carefully examine the contents of the Book of Seals.

Just as Uchiha Touyu had expected, not only was the Impure World Reincarnation not recorded, but even the first half of the Book of Seals, the Flying Thunder God Technique, was not recorded. Clearly, although the Third Hokage spoke generously, he actually kept a large part of it to himself.

Of course, it can't be said that the Book of Seals has nothing good in it. For example, the Eight Trigrams Seal, the Five Elements Great Combo, and even ninjutsu such as Creation Rebirth and the Eight Gates are all recorded in this book.

Unfortunately, these ninjutsu didn't fit Uchiha Touyu very well, so he only skimmed over them and ultimately stopped at an S-rank forbidden technique.

The Yin Escape Technique – Spirit Transformation Technique!

Upon seeing this secret technique, Uchiha Touyu's eyes lit up. To be honest, he was a little afraid that this secret technique might also be in the latter half of the sealed part!

The Spirit Transformation Technique originated from Kato Dansuke, the unfortunate ex-boyfriend of the legendary Sannin Tsunade. It is uncertain whether it is a family heirloom ninjutsu, a self-created ninjutsu, or a ninjutsu learned from the Scroll of Seals.

Of course, the fact that the Spirit Transformation Technique can now be seen in the Book of Sealing obviously rules out the possibility that it is a family-inherited ninjutsu. Perhaps he created it himself with his amazing talent and then recorded it in the Book of Sealing, or perhaps he also learned ninjutsu from the Book of Sealing.

Uchiha Touyu didn't care about this; the only thing he cared about was the effectiveness of this ninjutsu!

The effect of the Spirit Transformation Technique is simply a soul leaving the body to kill someone with the soul, which is somewhat similar to the feeling of a ghost immortal cultivator. Its advantages and disadvantages are also quite similar.

After the soul leaves the body, the perception is incredibly strong, the movement speed is lightning fast, and the soul can kill without being able to defend against it. These are all advantages of the spirit transformation technique.

The downside is that after the soul leaves the body, the physical body becomes stiff and unable to move without a master. If you are unlucky enough to be discovered, even a seven or eight-year-old child can stab you to death.

Essentially, this is a ninjutsu that makes killing and being killed very easy. Under normal circumstances, even if a ninja who has mastered this ninjutsu is very strong, he cannot be considered a true Kage-level powerhouse because of his obvious shortcomings.

However, for Uchiha Hiu, who possesses the ability to bind spirits and command generals, the Spirit Transformation Technique may have other wonderful uses.

The souls summoned by the Spirit Binding Technique are different from those summoned by the Spirit Transformation Technique; they cannot possess and kill.

If he could unleash the spiritification technique on the soul he controlled, its power would be extraordinary—there are almost no ninjutsu in the ninja world that can counter soul damage, so this move could be considered a deadly strike.

"Spiritualization Technique? Are you sure you want to choose this ninjutsu?"

The Third Hokage looked at Uchiha Touyu with some surprise. The Spirit Transformation Technique was not only extremely difficult, but also a very special specialized ninjutsu. Generally, only ninjas with exceptional talents would choose to learn it. Normal ninjas would definitely not choose such a double-edged sword ninjutsu.

Uchiha Touya's fighting style, which is exactly the same as Konoha's White Fang, is completely incompatible with the Spirit Transformation Technique. The only connection is the Uchiha's Sharingan, which belongs to the Yin Release bloodline and may only be of some help in training.

But for the Uchiha, developing the Sharingan is the right path, and the Spirit Transformation Technique doesn't really fit the Uchiha's fighting style.

"I'm sure, Hokage-sama!"

Seeing that Uchiha Touyu didn't care at all, the Third Hokage didn't try to dissuade him. Firstly, a ninja's training is a very personal matter, and secondly, he didn't think that the Spirit Transformation Technique would change the Uchiha in any way.

Afterwards, Uchiha Hiyu selected a few A-rank and B-rank practical ninjutsu from the Book of Sealing as supplements, and then handed the Book of Sealing back. The Third Hokage took out another scroll, casually formed a few hand seals, and then the garbled code on the Book of Sealing trembled and flowed into the other scroll.

After the garbled text on the Book of Seals leaked out, new garbled text appeared in the book in just a moment. The garbled text flowed into the scroll and transformed into normal characters.

A moment later, the transformation was complete. The Third Hokage tossed the scroll in his hand, and it flew directly into Uchiha Tou's arms. Then, he asked with a kind expression:

"Is there anything else?"

Uchiha Hiyu took the scroll, shook his head knowingly, and left with it.

As for what Orochimaru and the Third Hokage said afterward, that had nothing to do with Uchiha Touyu, and he didn't care.

Anyway, he didn't care whether his new cheap teacher became Hokage or not. He'd rather go back and learn about the Spirit Transformation Technique!

After returning home, Uchiha Hiyu first cleaned the house, which was covered in a layer of dust, and then opened the scroll in his hand to examine it carefully.

The first thing he watched was naturally the Spirit Transformation Technique. Having practiced the Spirit Binding and Commanding Technique, Uchiha Touyu had a good understanding of the soul, and therefore, he understood the Spirit Transformation Technique after only watching it once.

First, the Spirit Transformation Technique requires the soul to leave the body. A ninja must have extremely high proficiency in Yin Release chakra to be able to separate their soul from their physical body.

In addition, it is necessary to use chakra to create a shell that can contain the soul, so as to ensure the vitality and lethality of the soul. Otherwise, directly using the soul to attack other ninjas would result in mutual destruction.
