Starting to practice magic from Uchiha

In the quiet forest, a faint lightning suddenly lit up. A figure covered in lightning crossed the forest at a very fast speed. Huge trees with a diameter of one or two meters collapsed in an instant.

The light and shadow stopped instantly, revealing the figure of Uchiha Feiyu. He looked back at the tree he had cut down. The short knife in his hand flashed a faint light, as if it was a one-foot sword.

The weapon in Uchiha Feiyu's hand was not a weapon made of chakra metal. With his financial conditions, he could not afford that kind of good stuff.

This short knife is actually an ordinary standard weapon. It can have such a sharp sword light, which is entirely due to its superb chakra control skills.

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

Hatake Sakumo spoke in a faint voice. Chakra into blade is already a high-level skill in the White Fang Sword Technique. Even his son Kakashi has not yet learned this aspect. As a result, in the hands of Uchiha Feiyu, it has been learned in just two or three days.

Not only the Chakra Blade Technique, but also the rest of the Lightning Release to Strengthen the Body Technique, as well as the advanced Instant Body Technique and the matching swordsmanship techniques, Uchiha Feiyu has already mastered them now, and is only a little short of proficiency.

Uchiha Feiyu has a solid foundation to learn so quickly, and the observation and body control brought by the two Magatama Sharingans are also helpful, but in fact, what really allows Uchiha Feiyu to have such learning ability is the possession ability of the Soul Conqueror.

Hatake Sakumo controls Uchiha Feiyu's body through the possession ability to perform ninjutsu for training, which is equivalent to learning for ten days and a half months at a time. The learning effect of one day is comparable to two years of hard training, and two or three days is almost equivalent to teaching Uchiha Feiyu for five years.

With this learning efficiency, Uchiha Feiyu has almost mastered most of the essence of the White Fang Sword Technique, and the remaining are combat experience, chakra nature changes, depth of form changes and other basic issues.

Even if Uchiha Feiyu makes no progress in the future and just follows Hatake Sakumo's path, he can inherit 70% to 80% of Konoha White Fang's strength in the end, not counting his Sharingan bonus.

As for why he only inherited 70% to 80% of Konoha White Fang's strength? That's because White Fang has wind attribute chakra in addition to lightning attribute, while Uchiha Feiyu's own chakra has both lightning and fire attributes.

Although it is not impossible to develop the wind attribute after birth, and with Hatake Sakumo's help, it will take at most one year to practice the change of wind attribute chakra nature, but now that he is about to face the war, Uchiha Feiyu is still wise to put all his energy on the change of lightning attribute nature.

"By the way, Senior Sakumo, did you leave any ninjutsu scrolls?"

"I think my swordsmanship and ninjutsu still have room for improvement. I was planning to leave a legacy after a few years when the system is fully mature... So, why do you ask that?"

"Uh..., the ninjutsu I learned should at least have a source, don't you really leave nothing behind?"

"I did pass on the basics to Kakashi, but as for the more advanced ones, I plan to wait until Kakashi is ten years old and his body matures before passing them on to him."

"Well, Senior, you are ready to commit suicide, do you still want to take your swordsmanship to the underworld? Have you ever thought about leaving a legacy for your son!?"

"I didn't think so much at the time..."

Hatake Sakumo's suicide was a sudden act of being obsessed with a dead end. It would be strange to say that Hatake Sakumo really thought deeply before committing suicide.

After all, normal men who consider their eight-year-old son would not commit suicide because of some rumors.

Naturally, he didn't even consider the future of his eight-year-old son, so he naturally didn't care about his inheritance.

But now thinking back, Hatake Sakumo couldn't help but regret it. Apart from anything else, he should have left a legacy to his son!

Although Kakashi graduated at the age of five and became a Chunin at the age of six, he was a unique genius in the whole Konoha. In fact, at least half of Kakashi's achievements were due to Hatake Sakumo.

If it were an ordinary civilian ninja, no, even if his talent was not inferior to Kakashi, his growth rate would be much slower if he laid a good foundation since childhood.

Now without his guidance and the inheritance he left behind, Kakashi would definitely not be able to maintain the same growth rate as before, and he might die in the Third Ninja World War.

"Then let's do this, Senior Hatake Sakumo, you control my body and write a legacy on the spot, and then find a way to give it to Kakashi."

"Okay, that's the only way."

When Hatake Sakumo controls Uchiha Hiyu's body, he can also enjoy the bonus of the Sharingan bloodline at the same time. After the Sharingan is opened, Uchiha's body control ability will increase significantly in addition to the ability of the eyes, otherwise there is no way to directly copy other people's ninjutsu.

Relying on this method, plus Hatake Sakumo's original soul, the font written is exactly the same as the words written by Hatake Sakumo when he was alive, plus some of Hatake Sakumo's unique habits, there is no need to worry about Kakashi's suspicion.

After the inheritance scroll was written, Uchiha Hiyu looked at the scroll and asked the spirit around him:

"Sakumo-senpai, how do I hand this scroll of inheritance to Kakashi? Should I put it in a hidden place known to both you and Kakashi?"

"Just give the scroll to Kakashi! I have written instructions inside, so no one will be suspicious."

"Are you sure, senior? You and I didn't have any relationship before, so it's a bit too sudden to take out your scroll of inheritance."

"Hehe... It doesn't matter. Since my mission failed, you are the only ninja who has visited me many times. It's reasonable to hand over the scroll of inheritance to you."

"Okay, in that case, I will help you give this scroll to Kakashi. I hope this will help him get over it."

After hearing this, Uchiha Feiyu no longer refused. Even if someone had doubts, it didn't matter, because the inheritance in the scroll was absolutely true.

I believe that even if those ninjas had wild imaginations, they would not think of Uchiha Feiyu imprisoning the soul of White Fang. At most, they would sigh about Uchiha Feiyu's shit luck.

Moreover, with the inheritance of Hatake Sakumo, Uchiha Tobiha would no longer arouse suspicion when he uses White Fang's swordsmanship in the future. At the same time, by returning the inheritance, he could also narrow the distance between him and Kakashi and find a way to enlighten him.
