Konoha.
Yuzuru was playing with Uchiha Tsuki in the courtyard when a sudden system notification rang out in his mind.
[ Ding! Congratulations, Host. Your clan population has increased by over ten thousand. Bloodline evolution count +1! ]
[ Current clan population: 50,000! ]
"Yuzuru, what's wrong?"
Tsunade, standing nearby, noticed the smile spreading across his face and couldn't help but ask.
Yuzuru chuckled. "Nothing. I just realized that the number of newborns in the Uchiha clan has increased quite a bit recently."
Tsunade gave him a strange look and teased, "That's only natural. After all, as clan head, you've set a very important example."
He nearly choked on his own breath and quickly handed Tsuki over to her.
"I have something to take care of. Don't wait for me at dinner."
With that, he activated Kamui and vanished, entering the Kamui space alone.
Sitting cross-legged, Yuzuru silently opened his system panel.
At present, he had two bloodlines available for evolution.
The first was the Ice Release Kekkei Genkai inherited from the Yuki clan.
The second was the Shikotsumyaku inherited from the Kaguya clan.
Both were immensely powerful bloodline limits. If developed to their peak, either could possess world-shattering might.
After thinking for a long while, he chose to evolve the Shikotsumyaku.
According to his speculation, if the Senju clan and the Uzumaki clan inherited the Sage's body, and the Uchiha inherited the Sage's spirit, then perhaps the Kaguya clan had inherited the Sage's bones.
If he completed the evolution of the Shikotsumyaku, then his Sage Body should finally be perfected—the last missing piece.
With that thought, Yuzuru made his decision.
"Evolve Shikotsumyaku!"
The system prompt sounded again in his mind.
[ Ding! Shikotsumyaku evolution progress: 100%! Clan entry draw +1! ]
A warm current surged through his body, flooding his limbs and bones with indescribable comfort.
"As expected… Shikotsumyaku was the final piece to complete the perfect Sage Body."
He flexed slightly, feeling an endless stream of power surging within him.
His strength, which had long plateaued, rose once again at a terrifying rate.
Soon after, knowledge related to Shikotsumyaku flooded into his mind.
He opened his palm, and a white bone spike burst forth.
Unlike other Kaguya clan members, the spike he created was smooth and flawless, without the slightest blemish.
It was not purely white either—it faintly emitted a pale gray glow.
A powerful forbidden technique flashed through his mind.
All-Killing Ash Bones.
In the original tale, this was a power only Ōtsutsuki Kaguya could wield—a Kekkei Mōra ability.
Anything struck by it would turn to ash, leaving no chance of survival. Its lethality was beyond terrifying.
"No wonder the Kaguya clan's bodies couldn't withstand the power of Shikotsumyaku. Without a sufficiently powerful physique, they'd injure themselves before harming others."
As he pondered, he summoned a White Zetsu in front of him.
Without hesitation, he drove the bone spike into its body.
In the next instant, a perfectly smooth hole appeared in the White Zetsu's torso.
"As expected… still far from the power of All-Killing Ash Bones."
He muttered softly.
He had anticipated this result.
He had yet to fully step into the Six Paths realm, let alone grasp the higher-level power of Kekkei Mōra.
Next, Yuzuru drew the Kusanagi Sword from his waist and slashed down hard at the bone spike in his hand.
Clang!
The collision rang out sharply.
Upon closer inspection, there wasn't the slightest mark on the bone spike.
Seeing this, Yuzuru nodded in satisfaction.
The Kusanagi Sword was one of the Three Sacred Treasures, the sharpest and hardest blade in the ninja world.
Yet even such a weapon couldn't leave a mark on his bone. That alone spoke volumes about its hardness.
"Hahaha…"
He couldn't help but laugh heartily.
With his current physical strength, ordinary ninja would likely find it nearly impossible to break through his defenses.
The perfect Sage Body was just that overbearing.
After carefully sensing the changes in his body, Yuzuru turned his attention back to the system panel.
Because he had evolved Shikotsumyaku to 100%, he had obtained a chance to draw a clan entry.
[ System, draw clan entry! ]
[ Ding! Congratulations, Host. You have successfully drawn clan entry — ALL-AROUND DEVELOPMENT! ]
[ ALL-AROUND DEVELOPMENT: Clan members will elevate all aspects—Taijutsu, Genjutsu, Ninjutsu, etc.—to match their strongest specialty. ]
Yuzuru's eyes narrowed slightly as he read the description.
Another top-tier entry.
No one was perfect. Every ninja had strengths and weaknesses.
Some excelled in Taijutsu but lacked talent in Ninjutsu or Genjutsu.
Others might be gifted in Genjutsu or Ninjutsu yet comparatively weak in Taijutsu.
That was why intelligence and elemental counterplay often determined the outcome of battles.
But now, with ALL-AROUND DEVELOPMENT, the Uchiha clan would have no weaknesses.
Any area in which they lacked talent would be forcibly elevated to match their strongest field.
This effect was nearly comparable to the reward he had received when first awakening the system—raising all of his abilities to Kage level.
Combined with the previous clan entries, the overall strength of the Uchiha clan would undergo a qualitative leap.
Just imagining a future where every Uchiha possessed well-rounded Kage-level power made Yuzuru want to laugh.
With such a powerful clan, who in the ninja world could resist them?
Even setting their sights on the entire universe wouldn't be an exaggeration.
—————
Outside, the Uchiha clan members felt the surge of power in their bodies and wore excited expressions.
After the previous occurrences, they already knew the source of this miraculous power.
"Hahaha… It seems the Clan Head's power has taken effect again. I can feel my strength rising tremendously!"
"No matter how many times this happens, it still feels divine. I even wonder—could even a god accomplish something so incredible?"
"I can barely suppress the restless power inside me. When will the Clan Head launch an attack on the other nations?"
"Exactly! With strength like this, if we can't unleash it freely on the battlefield, what a waste that would be!"
