Lucky Draw Treasure Chest, Chakra Surges!

With the deaths of Tsuchikage Ishikawa, Mu, and other Iwagakure elites, this battle was already nearing its end.

Looking out, the vast Gobi battlefield had been shattered by Susanoo, countless corpses littering the ground in rivers of blood, a scene of utter devastation.

By rough estimate, at least a thousand ninjas had fallen.

The wounded were countless.

The entire landscape around Iwagakure had been drastically reshaped, with deep canyons stretching thousands of meters—a sight both shocking and terrifying.

The surviving ninjas were still fleeing, wishing they had never joined Iwagakure in the first place.

As for Natsu Yuu, from the moment he saw Madara activate his Perfect Susanoo, he was certain this battle held almost no suspense.

At the Super Kage level, wearing down an opponent through sheer numbers was nearly impossible.

The Third Raikage had once single-handedly fought ten thousand Stone Ninjas and only died from exhaustion.

And now, this newly established Iwagakure—where could it scrape together ten thousand ninjas?

Even if it somehow could, did anyone think the Perfect Susanoo was inferior to the Third Raikage's Lightning Release Armor?

Or that Madara's Chakra couldn't match the Third Raikage's, who could fight for three days and three nights?

Thus, the outcome of this battle had long been decided.

Blame it on the era—the concept of a Ninja Village had only just emerged. How many ninjas in Iwagakure, founded less than three months ago, were willing to fight to the death for it?

A few thousand against one man.

In a favorable battle, they could bully with numbers, but in an unfavorable one, who would willingly seek death?

Besides, even if they fought fearlessly to the last, did that mean they could defeat Madara Uchiha?

The brutal wars of the ninja world had never changed based on a ninja's will.

In the end, these ninjas from the Land of Earth suffered from a lack of experience. They had only heard of Hashirama and Madara's reputations, knowing they were powerful.

But just how powerful?

They had no clear understanding.

If it were the ninja clans in the Land of Fire, who had witnessed the battles between Senju and Uchiha, they would never have mustered the courage to oppose Madara.

Otherwise, why did the Sarutobi Clan, Shimura Clan, Hyuga Clan, and others immediately rush to join when they heard Senju and Uchiha were founding a village together?

Did they really think they were all fools?

The battle was over.

Madara was still clearing the battlefield, with a handful of Iwagakure loyalists stubbornly resisting, attacking him fearlessly.

Normally, having had his fill of fighting, Madara couldn't be bothered to waste time on these Sand Ninja.

But considering his deal with Natsu Yuu and the hope of reviving his younger brother Izuna, Madara decided to put in a little extra effort and completely slaughter these Iwagakure loyalists.

Natsu Yuu was very satisfied with this.

Truly, old Madara!

His reliability, his execution, his efficiency, his craftsmanship...

Even a born workaholic would have to bow in admiration.

With Madara and Hashirama around, unifying the ninja world was within reach!

Natsu Yuu excitedly opened the system and checked the Unification Progress increase for World 1.

[Naruto World 1 Unification Progress: 35% → 52%]

Sure enough, the progress had jumped significantly!

A full 17% increase!

It seemed the fall of Iwagakure was indeed crucial.

But how to fill the remaining 48%?

At this point in time, aside from Konoha and Iwagakure, the other three of the Five Great Hidden Villages hadn't even been formally established yet.

There was nowhere else to destroy!

As for the other small nations, they weren't even worth mentioning—the seeds for establishing ninja villages hadn't even sprouted yet.

Could it be that he had to slaughter every ninja clan within the other three nations?

Or perhaps he needed to completely destroy the other four great nations?

Destroying a ninja village wasn't difficult.

But conquering an entire nation? That was far from easy.

Either he annihilated it physically, which would exhaust even the Ten-Tails if he dragged it in to work, and there was no guarantee it wouldn't violate the definition of "unification."

Or he crushed it spiritually and culturally, which was equally taxing and required extensive preparation and scheming.

Natsu Yuu pondered for a moment and decided not to fret prematurely.

After all, he'd have plenty of time and energy to experiment later.

For now, he might as well use the rewards.

The unification progress had jumped from 35% to 52%, crossing the 40 and 50 thresholds, granting Natsu Yuu two draw chances.

He immediately opened the two lottery chests.

[Congratulations! You have obtained one (Modern Item Redemption Voucher)!]

[Congratulations! You have obtained one top-grade ninjutsu scroll Lightning Release: Raikiri!]

Natsu Yuu blinked.

He was familiar with the former—it had appeared in the Beginner's Gift Pack.

But what was the latter?

A ninjutsu scroll?

Lightning Release: Raikiri?

Using it would let him learn this technique?

Probably.

But why was it labeled "top-grade"?

Natsu Yuu opened the system and checked before he understood.

The ninjutsu scrolls from the system's lottery chests came in three tiers: Common, Rare, and Top-Grade.

[Common Ninjutsu Scroll] only allowed the user to quickly master the recorded technique.

[Rare Ninjutsu Scroll] allowed the user to master the recorded technique extremely quickly and granted a certain amount of Chakra enhancement.

[Top-Grade Ninjutsu Scroll] allowed the user to instantly master the recorded technique, granted a large amount of Chakra enhancement, and provided the corresponding Chakra nature.

So, his luck was pretty good!

He'd pulled a top-grade ninjutsu scroll on his first try.

Wait—it could grant a large amount of Chakra?

He was exactly short on Chakra!

Although he had [World Teleportation] as a safety net and a pair of powerful [Rinnegan], his physical constitution was too weak and his Chakra too scarce to unleash the Rinnegan's true power.

Perfect timing—he could improve right away.

He liked this kind of system—giving him exactly what he lacked!

Far better than those other systems that treated their hosts like donkeys and were stingy to boot.

So Natsu Yuu decisively activated the ninjutsu scroll.

The scroll dissolved into specks of light, rapidly merging into Natsu Yuu's body.

A flood of ninjutsu and taijutsu knowledge poured into his mind, instantly allowing him to master the S-rank technique [Lightning Release: Raikiri].

[Raikiri] wasn't just a ninjutsu—it also included a powerful set of taijutsu charge techniques.

Though nominally the same as [Chidori], its taijutsu difficulty and power were clearly higher.

But that wasn't what Natsu Yuu cared about.

The key point was.

This [Top-Grade Ninjutsu Scroll] had indeed granted him an additional Chakra nature.

His own Chakra nature had expanded from [Fire, Wind] to [Fire, Wind, Lightning]—three natures total.

Beyond that.

His originally meager Chakra had surged dozens of times over!

And it was a permanent increase to his upper limit!

Simply put, Natsu Yuu's physical constitution and mental strength had both skyrocketed as a result!

Without concrete metrics, he couldn't gauge exactly what level his Chakra enhancement had reached.

But far stronger than the two Stone Ninja who had just popped up!

Enough for him to fire off several [Shinra Tensei]!

That way, even if he couldn't kill the enemy—

At the very least, he could freely activate the unique abilities of both [Rinnegan] and keep experimenting with new Dojutsu.

Natsu Yuu was overjoyed, brimming with excitement.

He wanted to keep trying new applications of [Kagutsuchi], or fire another high-powered 'Railgun' to see if he could blow the top off a small mountain!

But over on the distant battlefield, Madara had just finished his cleanup work.

And was heading back toward him.

Natsu Yuu had no choice but to suppress his excitement and prepare to receive this 'great contributor to the village's destruction.'
