Sakumo's Legacy

Kyosuke had always focused primarily on his Fire and Earth chakra affinities, so he rarely paid much attention to ninjutsu of other natures.

But after learning this Lightning Release technique, he felt that his grasp of the "Lightning" nature transformation had actually improved by a small margin.

Surprised, he went to the clan's jutsu library and found a piece of chakra paper.

After testing it, he could finally confirm that learning a ninjutsu of a certain nature through the system did indeed increase his development in that corresponding affinity.

Of course, this was also quite realistic.

In reality, if you wanted to learn a high-level ninjutsu, you had to have a certain degree of mastery over both the shape and nature transformation of its chakra.

The system, however, had simply reversed this entire process.

In other words, no matter what ninjutsu Kyosuke learned, the system would inevitably raise his development in the relevant chakra nature based on the difficulty of the technique.

The benefits of this were obvious. Otherwise, even with the system's help, it would take him who knows how long to master the development of all chakra natures.

"Bang~ Bang~ Bang~" A sudden, urgent knock shattered the peace within the Hatake Clan's compound.

"Who is it, knocking so early in the morning?"

After a moment, six-year-old Kakashi rubbed his eyes and slowly opened the door.

Then, he saw a ninja whose clothes bore the Uchiha crest.

Instantly, Kakashi's drowsiness vanished.

"The Uchiha Clan... what do you want?" Kakashi asked warily, staring at the man at the door.

"Hmph." The ninja sneered at Kakashi's expression, then tossed a letter stamped with the character for "Challenge" at him.

At the same time, he looked down at Kakashi and said, "I represent Kyosuke Uchiha in formally challenging you. The time is set for noon, three days from now. Do you dare to accept?"

Kakashi lowered his head and looked at the challenge letter in his hands, momentarily unsure how to respond.

Just then, a chilling killing intent suddenly enveloped the Uchiha ninja.

Then, a slightly weary figure slowly emerged from the inner hall.

As his footsteps advanced, the psychological pressure on the ninja grew heavier and heavier.

It wasn't until he stumbled and fell to the ground that the terrifying killing intent finally disappeared.

The newcomer was none other than Hatake Sakumo, known as the Konoha White Fang.

But looking at him now, it was hard to imagine he had once been such a powerful ninja.

This showed just how damaging rumors could be to a person.

Especially for a ninja like Hatake Sakumo, who placed great importance on honor—their impact was even greater.

"A challenge letter?" Sakumo forced himself to stay alert, recalled what he knew about Kyosuke Uchiha in his mind, and asked his son, "What do you say?"

The still-young Kakashi looked at his father, then thought of the recent rumors, and his expression suddenly turned serious. "I accept his challenge."

Hearing Kakashi's reply, the Uchiha ninja slowly got up from the ground.

He first cast a cautious glance at the silent Sakumo, then quickly said to Kakashi, "See you in three days," before swiftly departing.

After the ninja left, the pale-faced Sakumo suddenly said to Kakashi, "Follow me to the yard."

With that, he quickly walked toward the yard, and Kakashi hurriedly followed.

Soon, the two stood in the yard, facing each other from several meters apart.

Hatake Sakumo looked at his son, who was gradually growing taller, smiled warmly, and slowly drew his beloved blade, "White Fang."

The blade was pure white all over, slightly heavier than an ordinary tanto.

Though not particularly long, the faint chakra glow emanating from it seemed to tell everyone that this was a deadly weapon.

"This is my most trusted weapon. I've used it to carry out countless missions and cut down countless enemies." Sakumo gently stroked the blade, then sheathed it and tossed it straight to Kakashi.

Kakashi caught it and looked at Sakumo. "Father... this is?"

Hatake Sakumo smiled gently again and said, word by word, "From today on, it belongs to you!"

"Really?!" Kakashi exclaimed in surprise, then began to fondle it with great affection, unable to put it down.

Sakumo ignored his son's question and instead said, "Haven't you always wanted to learn my swordsmanship? I'll teach it to you today."

Kakashi immediately looked up at his father.

Perhaps because the surprises today had come too fast and too many, he was momentarily at a loss for words.

But at the same time, a bad feeling stirred in Kakashi's heart.

His father felt strange today, but he couldn't quite put his finger on why.

Frustrated, Kakashi scratched his head.

Just then, a flash of bright blade light suddenly passed before his eyes.

The blade light grazed past Kakashi's body and finally split the large boulder in the yard cleanly in two.

But Kakashi hadn't even noticed when his father had drawn the blade.

That stunning slash made him forget everything else.

At this moment, he had only one thought in his mind—to learn it.

"When the White Fang bares its light, it becomes the sharp tooth that devours the darkness."

"This is the entire essence of my blade technique."

"Did you understand?"

Kakashi first nodded, then hesitated slightly.

Seeing this, Sakumo smiled and said, "Don't rush. You still have three days to master it."

"I understand, Father." Kakashi nodded solemnly, then turned his head to glance at the massive boulder again, a faint thrill stirring in his heart.

But at this moment, he had no idea what his father meant by those three days.

"Hey~ Kyosuke, Grandfather told me to let you know—Kakashi has accepted the challenge." Nagisa bounced into Kyosuke's room and delivered the news.

"Accepted, huh." Hearing her words, Kyosuke's expression didn't show much joy.

"What's wrong?" Nagisa keenly noticed this and asked with a hint of concern.

Kyosuke silently shook his head, not answering her question. Instead, he brought up something else: "I heard you've been training hard lately. Since I'm free today, I'll check on your progress."

Perhaps because of this challenge mission, Danzo had specially given him a few days off to adjust his state.

So here he was, lounging at home with nothing to do.

Nagisa was successfully distracted by Kyosuke's words. She lifted her little chin with a hint of pride, gave a light snort, and said, "Then you'd better watch out. Don't accidentally lose to me—that'd be embarrassing~~~"

"Haha." Kyosuke finally let out a laugh. Grabbing the girl's ponytail, he dragged her—amid her yelps of protest—to the clan's Training Ground.

"Come on, I'll give you one hand."

"Hmph, arrogant. Watch my Ninjutsu~"
