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

Chapter 10 Rapid Advancement and Forged Legacy

In the quiet forest, a faint flash of lightning suddenly appeared. A figure covered in lightning streaked across the trees at an incredible speed, and huge trees, one or two meters in diameter, collapsed in an instant.

The light and shadow froze for a moment, revealing the figure of Uchiha Hiyu. He glanced back at the tree he had cut down, and the short sword in his hand gleamed with a faint light, as if it were a foot-long sword blade.

The weapon that Uchiha Touyu held in his hand was not made of chakra metal; he couldn't afford such a good weapon given his financial situation.

This short sword is actually just an ordinary standard weapon. Its sharp edge is entirely due to the user's superb chakra control skills.

"You learn really fast... I didn't even teach Kakashi these things..."

Hatake Sakumo spoke in a low voice, "Chakra Blade Transformation is already considered a high-level technique that is the most powerful secret in the White Fang Sword Technique. Even his own son, Kakashi, has not yet learned this technique. However, Uchiha Touyu learned it in just two or three days."

Not only the chakra blade technique, but also the lightning release body enhancement techniques, the advanced body sleight of hand, and the accompanying swordsmanship skills, all of which Uchiha Tou has now mastered, only lacking a little proficiency.

The fact that Uchiha Touyu was able to learn so quickly was partly due to his solid foundation, and partly due to the observational and body control abilities brought by his two-tomoe Sharingan. However, what truly enabled Uchiha Touyu to have such a learning ability was the possession ability of the Spirit Binding General.

Hatake Sakumo used his possession ability to control Uchiha Tou's body to perform ninjutsu training. One session was equivalent to ten or fifteen days of study, and the learning effect of one day was comparable to two years of hard training. Two or three days was roughly equivalent to teaching Uchiha Tou by hand for five years.

With this level of learning efficiency, Uchiha Touyu had already mastered most of the essence of the White Fang Sword Technique. The remaining issues were fundamental aspects such as combat experience, chakra nature transformation, and the depth of form transformation.

Even if Uchiha Touyu doesn't make any further progress and just follows in Hatake Sakumo's footsteps, he will eventually inherit 70-80% of Konoha's White Fang's strength, not even counting the bonus from his Sharingan.

As for why he only inherited 70-80% of Konoha's White Fang's strength, it's because White Fang possessed wind chakra in addition to lightning chakra, while Uchiha Tou's chakra was both lightning and fire chakra.

Although developing wind attribute later in life is not impossible, and with Sakumo Hatake's help, it would only take a year at most to master wind attribute chakra nature transformation, Uchiha Touya wisely focused all his energy on lightning attribute nature transformation in the face of impending war.

"By the way, Sakumo-senpai, did you leave behind any ninjutsu scrolls?"

"I feel there's still room for improvement in my swordsmanship and ninjutsu. I was originally planning to leave a legacy a few years later, once my system was fully mature... By the way, why did you ask that?"

"Uh... all these ninjutsu techniques I learned should at least have some origin, right? Did you really leave nothing behind?"

"I've taught the basics to Kakashi, but as for the more advanced stuff, I plan to teach it to him after he turns ten and his body has matured a bit more."

"Um, senior, you're already preparing to commit suicide, do you intend to take your swordsmanship to the underworld? Didn't you think about leaving a legacy for your son!?"

"I didn't really think that much about it at the time..."

Sakumo Hatake's suicide was a sudden act of delusion; it would be strange to say that he had given it much thought beforehand.

After all, any normal man who considers his eight-year-old son would not commit suicide because of some rumors.

Naturally, he hadn't even considered the future of his eight-year-old son, so he certainly didn't care about passing on his legacy.

However, looking back now, Hatake Sakumo can't help but regret it. Putting everything else aside, he should at least have left a legacy for his son!

Despite Kakashi graduating at five and becoming a Chunin at six, making him a unique genius in the entire Hidden Leaf Village, at least half of Kakashi's achievements are attributable to Sakumo Hatake.

If it were an ordinary civilian ninja, without a solid foundation from childhood, even if their talent was in no way inferior to Kakashi's, their growth rate would be much slower.

Now that he has lost his mentor and the legacy he left behind, Kakashi will certainly not be able to maintain the same growth rate as before, and may even die in the Third Shinobi World War.

"Alright then, Sakumo Hatake-senpai, you control my body and write down a legacy on the spot, then find a way to give it to Kakashi."

"Alright, that's the only way then."

When Sakumo Hatake was controlling Tou's body, he was also able to enjoy the enhancement of the Sharingan bloodline. After the Sharingan was activated, in addition to the abilities of the eyes, the Uchiha's ability to control his body would also be greatly increased. Otherwise, he would not be able to directly copy other people's ninjutsu.

Using this method, combined with the original soul of Hatake Sakumo, the handwriting produced was exactly the same as the handwriting Hatake Sakumo used when he was alive. In addition, with some of Hatake Sakumo's unique little habits, there was no need to worry that Kakashi would have any doubts.

After the scroll of inheritance was completed, Uchiha Touyu looked at it and asked the spirit beside him:

"Senior Sakumo, how am I supposed to hand over this inheritance scroll to Kakashi? Should I find a secluded spot that both you and Kakashi know about and put it away?"

"Just give the scroll to Kakashi! I've already written the instructions inside, so no one will suspect anything."

"Are you really sure, senior? We've never had any connection before, so it's a bit too sudden for you to suddenly pull out your inheritance scroll."

"Hehe... It's alright. Since my mission failed, you're the only ninja who has visited me multiple times. It's only fair to give you the inheritance scroll."

"Alright, in that case, I'll give this scroll to Kakashi for you. Hopefully, it will help him get through this."

Upon hearing this, Uchiha Touyu no longer declined. Even if some people had doubts, it didn't matter, because the inheritance inside the scroll was definitely genuine.

Even if those ninjas had wild imaginations, they probably wouldn't have thought that Uchiha Touyu had imprisoned White Fang's soul. At most, they would just marvel at Uchiha Touyu's incredible luck.

Furthermore, with the legacy of Hatake Sakumo, Uchiha Touya will no longer be suspected when using White Fang's swordsmanship. At the same time, by returning the legacy, he can also get closer to Kakashi and try to enlighten him.
