Clan-Wide Enhancement Plan

Naka River Shrine, underground chamber.

The dim yellow candlelight stretched Xuan Shi's shadow long across the floor. He sat cross-legged before the table, the system panel in front of him giving off a faint, ghostly blue glow that only he could see.

[Current clan prosperity: 315 points]

This was the biggest gain he had made in this period. The perfect rating from the S-rank mission, the hidden reward from allying with the Fourth Hokage, plus the steady daily returns from Shisui continuing to send back intelligence from Root, had finally made that shriveled number look a little healthier.

"315 points..."

Xuan Shi rubbed his chin.

If he exchanged it all for the kind of "High-Purity Hashirama Cell Extract" used on Shisui (50 points per vial), he could only get six vials. For the entire clan, that was a drop in the bucket.

His gaze moved down and locked onto another product.

[Product: Hashirama Cell Extract (Diluted Version/Mass-Production Type)]

[Effect: increases bodily activity by approximately 15%, increases chakra limit by approximately 20%, repairs minor optic nerve damage.]

[Applicable users: Three-Tomoe Sharingan possessors (physique must meet jonin standard).]

[Price: 10 points/vial.]

Although the effect was discounted, its strength lay in quantity and reliability. For those clan members who had not yet awakened the Mangekyo and served only as the backbone of their fighting force, this was already a miracle drug.

"Exchange for 30 vials."

Xuan Shi did not hesitate.

[Prosperity consumed: 300 points. Exchange successful.]

An exquisite wooden box appeared out of thin air on the tabletop, with thirty test tubes neatly arranged inside, each giving off a faint green fluorescent glow.

Late at night.

The chamber's great doors closed once more, cutting off all probing from the outside world.

Thirty elite Uchiha jonin knelt in the center of the training ground. They were all core pillars of the clan, including Yashiro Uchiha, Uchiha Tekka, Inabi, and the others.

Everyone's eyes burned as they stared at that wooden box.

Just moments ago, they had personally witnessed the new power Shisui displayed on the training ground—that endless flow of chakra, that insight sharpened to the extreme. It was as if he had become an entirely different person.

"This is the clan's secret medicine."

Xuan Shi picked up a test tube and did not explain that these were Hashirama cells—it would be too troublesome to explain, and it could easily cause panic. He simply defined it as "secret medicine."

"It can make up for the Uchiha Clan's greatest weaknesses—insufficient chakra reserves, and bodies that aren't tough enough."

"The process will be extremely painful, like having your bones shattered and rebuilt. Anyone afraid of pain can withdraw now."

No one moved.

As shinobi, as Uchiha, the thing they feared least was pain. What they feared was powerlessness. What they feared was only being able to watch helplessly as their loved ones fell on the Night of Clan Extermination.

"Good."

Xuan Shi waved his hand. "Begin. Five people per group. Take turns injecting it."

For the next two hours, the chamber became a hell in the truest sense.

Suppressed growls rose and fell one after another.

Even Yashiro, whose temperament was the most tenacious, could not help biting through the wooden stopper in his mouth the moment the medicinal fluid was pushed into his veins. Veins bulged all over his body, and sweat instantly soaked his clothes.

It felt as if ten thousand ants were gnawing at his bone marrow, and also as if scalding molten iron had been poured into his blood vessels.

Xuan Shi, Fugaku, and Shisui stood guard at the side with full concentration.

The moment anyone showed an excessively intense rejection reaction, they would immediately use chakra to suppress and guide it.

Fortunately, this batch of diluted medicine was much gentler. On top of that, all thirty of these people were battle-hardened elites, their willpower far beyond that of ordinary people.

Finally.

When the last clan member stopped trembling and climbed up from the ground, even the air in the chamber seemed to change.

It was the scent of chakra.

The air that had once been heavy was now filled with active, restless ripples of energy.

"Hoo..."

Uchiha Tekka clenched his fist, and his knuckles let out crisp cracks.

He casually formed a Fire Release hand seal—he did not release ninjutsu, merely mobilized his chakra.

Buzz!

A visible wave of heat spread out from him as the center.

"This feeling..." Tekka stared at his own hands in disbelief. "The flow speed of my chakra is twice as fast as before! And the total amount... it feels like I'll never run out no matter how much I use!"

"Not just that."

On the other side, Inabi activated his Three-Tomoe Sharingan. "My eyes don't feel dry anymore either. In the past, I'd feel tired after maintaining the three-tomoe state for half an hour. Now it feels like I could keep it open all day."

Fugaku looked at this scene, and a trace of excitement flashed through his eyes.

"Because the Uchiha Clan relies too heavily on our eyes, our physical quality often falls short of the Senju Clan's. That is also the reason we are prone to suffering losses in drawn-out battles."

Fugaku sighed. "This medicine perfectly makes up for our physical shortcomings. The current us, even without activating our eyes, can clash head-on with those shinobi who specialize in taijutsu through nothing but taijutsu and chakra volume."

Xuan Shi looked at the system interface.

Although this batch of medicine could not help them awaken the Mangekyo, quantitative change led to qualitative change.

Thirty elite jonin with abundant chakra, tough bodies, and the Three-Tomoe Sharingan. This was a force that, placed anywhere in the shinobi world, would be enough to destroy a nation.

"It's not over yet."

Xuan Shi walked to the center of the chamber and signaled for everyone to quiet down.

He looked at these utterly renewed clan members, and the bold tactical concept in his mind finally had the foundation needed for implementation.

"The individual enhancement is complete. But against a chakra monster like the Nine-Tails, an individual's strength is still insignificant."

Xuan Shi's gaze swept over Fugaku, Shisui, and Itachi—although Itachi had not been injected, his talent was exceptional.

"We need a jutsu that can 'link' everyone's power together."

He took an ancient scroll from his robes—it was one he had found in a corner of the system shop, a long-sealed Uchiha forbidden technique.

"There is an ancient formation sealed away in the system—Susanoo Resonance Formation."

Xuan Shi unfurled the scroll. Complex formation patterns were drawn across it.

"As long as there are three pairs of Mangekyo Sharingan acting as the core guiding nodes."

He pointed at himself, then at Fugaku and Shisui.

"We can gather the chakra of these thirty clan members together and break through the limits of an individual Susanoo."

A fanatical light flashed in Xuan Shi's eyes.

"We are going to condense a divine giant... one that surpasses a perfect body, and can even brawl with the Nine-Tails."

"Tonight, we'll test this formation."
