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

Chapter 2: Sparring with Kakashi

As Uchiha Touyu finished speaking, Kakashi's expression faltered slightly, but he quickly recovered:

"Alright, it's a deal!"

Kakashi's father, Sakumo Hatake, was the renowned White Fang of Konoha, one of the most powerful ninjas in the entire Hidden Leaf Village.

And now is precisely the time when Konoha's White Fang is at the height of his fame, renowned throughout the land. He can be said to be the most famous ninja in the entire Hidden Leaf Village besides the Hokage.

For Kakashi, it was perfectly normal for someone to want to visit his father, and he didn't think much of it.

Uchiha Touya wanted to meet Konoha's White Fang, not because he admired White Fang's reputation, but because he wanted to learn from him.

On the contrary, Uchiha Touyu thought of the original story, where Hatake Sakumo failed in his mission around the same time and then committed suicide amidst rumors—he was eyeing Hatake Sakumo's soul!

The Soul Binding Technique, one of the Eight Extraordinary Techniques in the world of Under One Person, is a unique technique that forcibly binds or even devours the souls of others. Its power depends entirely on the soul reserves held by the user.

Unfortunately, there are no wild souls in the Naruto world. Generally speaking, after any creature dies in this world, its soul will dissipate and go to the Pure Land if more than ten minutes have passed.

Therefore, despite searching diligently for over a decade, Uchiha Hiu, who had remained in Konoha Village, was unable to find the soul of any ninja.

No matter how dangerous the Naruto world is, Konoha Village is relatively safe for the time being, and it is almost impossible to find the body of a ninja who has just died within ten minutes.

Uchiha Tou even went to Konoha Hospital to wait for them, only to find that due to the widespread use of medical ninjutsu, almost all the ninjas who were sent to Konoha Hospital could be saved, and those who couldn't be saved had already died before even being sent to Konoha Hospital.

There are also places like the interrogation squad, the intelligence squad, and Konoha Prison, where one can come into contact with fresh dead bodies, but these are all vital parts of Konoha Village, and are not places that a ninja trainee can access.

So even now, Uchiha Touya only has some animal souls in his possession, and has never obtained a ninja soul.

Most of the animal souls were directly consumed by Uchiha Hiyu. He couldn't devour human souls, but he had no psychological burden in absorbing animal souls. Moreover, most animal souls, even if they possessed him, wouldn't be able to exert much combat power, so they were not very meaningful to begin with.

It was precisely because of the souls of these animals that possessed chakra that Uchiha Tou was outstanding in both physical attributes and chakra reserves among his peers and even among other Uchiha of the same age—but only among his peers.

Having understood these circumstances, it becomes clear how alluring the soul of a ninja of Konoha's caliber would be to Uchiha Touya.

Even if possessing a soul doesn't allow one to unleash the full power of the original owner, a powerful figure like Konoha's White Fang is enough to instantly grant Uchiha Touyu top-tier combat strength among Jonin.

However, right now, Uchiha Tou's first priority is to deal with the enthusiastic Kakashi.

A howling wind blew past, and Kakashi casually drew a short sword from his waist, its cold light flashing on the blade.

Before Konoha's White Fang committed suicide, the White Fang short sword was certainly not in Kakashi's possession, but its quality was absolutely top-notch.

Compared to Kakashi, Uchiha Tou casually pulled out two kunai. Although he had joined the Uchiha clan, it was obvious that the Uchiha clan wouldn't put much effort into him, an "outsider," so his equipment was quite ordinary.

However, after gripping the two kunai tightly, a black leopard-shaped soul suddenly appeared on Uchiha Hiyu's body.

This is the strongest beast soul he once collected in the Forest of Death, a black panther with incredible speed. By using his ability to control spirits, he can make Uchiha Touyu's nerve reflexes and physical speed increase by 50%.

Kakashi couldn't see the soul, but sensing the sudden change in Uchiha Tou's aura, his expression also showed some excitement, and subtle sparks of electricity began to dance on his body.

By stimulating his own cells with lightning-style electric currents to accelerate his speed, Kakashi clearly inherited his father's signature technique.

With a flick of his wrist, Fei Yu flung the kunai at Kakashi. It wasn't some fancy kunai-throwing technique typical of the Uchiha clan; it was simply a swift and sharp throw.

Kakashi slashed his short sword, producing a sharp, short clang. The kunai, imbued with immense force, sent a jolt through Kakashi's wrist.

Following closely behind, Fei Yu raised his kunai high. Although it was a short weapon, he used it with the flair of a heavy weapon like a hammer or club, and smashed it down.

Kakashi gritted his teeth slightly, raised his slightly numb arm, and sparks flew as the short sword and kunai clashed. At the same time, Kakashi staggered back several steps.

"So heavy... Are you really an Uchiha? Your fighting techniques are so similar to Guy's!"

"Sorry, although I possess the Sharingan of the Uchiha clan, I didn't receive any formal education from the Uchiha community from a young age. Compared to flashy techniques, I believe more in a solid physical foundation forged through countless trials!"

In fact, Uchiha Tou had already planned his future training path, and physical foundation was the most important thing for him when he was building his foundation.

As for skills and such, they can be made up for by acquiring ninja souls later, but in any case, one's physical foundation can only be honed by oneself.

Moreover, the Spirit Absorption Technique has comprehensively enhanced Fei Yu, not only his chakra and spiritual power, but also his physical strength. This makes Fei Yu's current fighting style not at all like the Uchiha, but rather somewhat like the Senju clan.

Kakashi took two steps back, his figure flashed, and he immediately activated the Substitution Jutsu. The ever-attacking Fei Yu cleaved the Substitution Wood in two with a single slash. With a slight frown, he turned around and kicked out.

Kakashi, who appeared behind Feiyu, was kicked into a puff of white smoke by Feiyu with a bang. Then, a white light descended from the sky and pierced straight into Feiyu's shoulder.

"I've been waiting for you!"

Fei Yu chuckled lightly and retreated in an instant, dodging Kakashi's ambush. As he retreated, the kunai in his hand transformed into a streak of black light and shot towards Kakashi's chest.

While possessed by the Black Panther's spirit, in addition to speed and reflexes, Uchiha Touyu's five senses and intuition would also be greatly enhanced, making him completely impervious to clone techniques and substitution techniques.

Kakashi, whose ambush attempt failed and who was instead caught off guard by Uchiha Touyu, barely managed to deflect the kunai. Before he could catch his breath, Uchiha Touyu, who had drawn two more kunai, pounced on him again.

After blocking several attacks with a clanging sound, Kakashi retreated repeatedly, but gradually calmed down.

With the Black Panther's soul possessing him, Uchiha Touya's speed is almost on par with Kakashi's when he uses the Lightning Release: Stimulation Technique, and in terms of pure physical strength, he far surpasses Kakashi, who is only nine years old at the time.

However, Kakashi, the genius ninja, still discovered Uchiha Hiu's only weakness—his taijutsu and ninja tool skills were only solid in foundation and his body was strong, but his technique was not outstanding.

After all, Uchiha Touyu did not receive a good education or training. Needless to say, the Konoha Ninja Academy only taught the most basic things. The Uchiha clan only gave Uchiha Touyu some basic ninjutsu books and materials, and did not really train him.

In contrast, there is Kakashi Hatake. An eight-year-old child's physical abilities are far from being developed to their limit. Even with the stimulation of Lightning Release chakra, there are still great shortcomings in physical strength. However, if we only talk about swordsmanship skills, Kakashi Hatake, who was trained by Konoha's White Fang, is far superior to Touya Uchiha.

Having discovered the flaw in Uchiha Tou's technique, Kakashi didn't hesitate and stopped directly confronting Uchiha Tou. He used his short sword to draw arcs of light, employing techniques such as sticking, adhering, and drawing to deflect the force of the kunai in Uchiha Tou's hand.

After Kakashi switched to his fighting style, Uchiha Touyu was indeed in great pain. However, thanks to the black panther soul that was possessing his body, Uchiha Touyu's five senses and intuition were extremely sharp.

Thanks to this keen sense, Kakashi had the upper hand, but it would be difficult for him to defeat him in a short time.

Snowflakes flew up from the snow-covered ground, accompanied by the clanging of weapons clashing and sparks flying. Two figures moved through the woods and separated in an instant.

Uchiha Touyu frowned slightly as he looked at his torn white clothes.

Kakashi Hatake, standing opposite him, was completely unharmed, though he was breathing rapidly and had fine beads of sweat on his forehead.

Although Kakashi had gained a certain advantage, the physical condition of an eight-year-old child still limited his stamina. The all-out battle that lasted for more than ten minutes had severely depleted Kakashi's stamina.

"It seems I've lost. Kakashi, your progress is truly remarkable. As expected of Konoha's most famous genius."

Blood slowly seeped from Uchiha Tou's torn clothes, gradually staining his sleeves red. Uchiha Tou casually pulled out gauze from his ninja tool bag, wrapped it around his arm, and bandaged the wound.

The wound wasn't deep, and it didn't even have much impact on Uchiha Tou's battle, but it undoubtedly meant that Uchiha Tou had been defeated.

Kakashi took a couple of deep breaths. His victory wasn't easy; if he had fought for a few more minutes until he was exhausted, he probably would have been the one to lose.

Neither of them used any lethal ninjutsu during the battle, so although Kakashi was quite exhausted, he still had plenty of chakra and recovered after catching his breath.

"If you were more proactive, you could probably get a lot of resources too!"

"Since you've been secretly cultivating here every day, why don't you perform even better and ask your family and village for more resources?"

To Kakashi's question, Uchiha Touyu simply chuckled and offered no further explanation.

With the ability to bind spirits and command generals, he doesn't need to worry about not having any ninjutsu to use in the future. On the contrary, if he gets too many resources from the village or clan, he will probably find it difficult to slack off.
