With the death of Tsuchikage Ishikawa and the fall of his elite retainers like Mu,the battle had, for all intents and purposes, ended.
All around them, the once-proud battlefield of the Stone Country had been torn apart by Madara's complete Susanoo—its massive chakra blades gouging canyons into the land and painting the terrain in a river of blood.
A rough sweep of the field revealed that thousands of Iwagakure shinobi had died.
The wounded?Countless.
The very landscape had changed.The terrain near the village was split wide open, now carved by deep ravines stretching for kilometers.
What remained of the Iwagakure forces had long since scattered in terror.They ran like broken dogs, cursing the day they'd ever pledged allegiance to a newborn village.
As for Kai, who stood atop a ridge in the distance—he wasn't surprised.
From the moment Madara summoned the Complete Susanoo,there was no suspense left.
At this point, Super Kage-level fighters weren't something you could take down with numbers alone.It was nearly impossible.
The Third Raikage had managed to fight off 10,000 shinobi from the Hidden Stone—and still fell to exhaustion in the end.
But this wasn't that.
This was early in the ninja village era—and the Hidden Stone hadn't even reached the strength it would have decades later.
Could they even gather 10,000 elite shinobi?
Did they have anyone stronger than the Third Raikage?
Could a freshly built Hidden Stone outlast Madara's full Susanoo, powered by eternal Mangekyō Sharingan?
Not a chance.
No matter how you looked at it,this battle had been doomed from the start.
This was still an era where the ninja village system was in its infancy.How many shinobi were truly willing to die for a name like "Iwagakure"?
A force of thousands against a single man…
When morale was high, they could push forward like a tide.
But when the tide turned?Everyone bolted.
And even if they all stood their ground,did they really think they could kill Uchiha Madara?
This war had nothing to do with individual will.The shinobi of the Land of Earth lacked real combat experience.They'd heard of Madara's reputation—yes.
They knew Senju Hashirama and Uchiha Madara were terrifying—yes.
But how terrifying?
They had no reference. No sense of scale.
If it were the ninja clans of the Fire Country—those who'd personally seen the Senju and Uchiha go to war—
They wouldn't have dared to fight in the first place.
Why did the Sarutobi, Shimura, Hyuga, and the rest run to join Konoha the moment Senju and Uchiha allied?
Did they look like fools to you?
They knew exactly what was coming.
The war was over.
On the battlefield, Madara continued to clean up the last pockets of resistance.
Some diehard shinobi still stood their ground, throwing themselves at him with suicidal resolve.
If this were any other day,Madara might have ignored them.He'd danced enough.
But today, he had reason to keep going.
Because of his deal with Kai.
Because he wanted to revive his brother, Izuna.
Because he knew this was the price of that future.
And so, he slaughtered every last hideout.
Efficiently.
Without hesitation.
Watching from afar, Kai nodded in approval.
"That's Old Madara for you."
Reliable. Meticulous. Ruthless.A true professional.
If every world's unification had a Madara and a Hashirama like this,Kai wouldn't have to worry about anything.
He opened his system interface immediately to check the changes in progress.
[Unification Progress - Naruto World No. 1: 35% → 52%]
17%!!
A massive leap.
So the destruction of Hidden Stone really was a major event in the unification timeline.
That left 48% to go.
But now came the problem.
At this point in time, only Konoha and Iwagakure had taken shape.
The other three great villages hadn't even been officially founded yet.
So what was he supposed to destroy next?
The three remaining great nations hadn't centralized their clans.
Some smaller countries hadn't even decided to go the "one nation, one village" route.
What was he supposed to do—kill every ninja in the world?
Destroy all five nations entirely?
Even if you had the Ten-Tails to help carry supplies,physically wiping out a nation would be exhausting.
And spiritually "conquering" a country was even harder.
That required an ideological shift, cultural assimilation, and prolonged psychological brainwashing.
Not something you could brute-force.
Kai scratched his head.
"Forget it for now."
There'd be time for that later.
For now—there was a more urgent matter.
Opening his loot.
Thanks to the jump from 35% to 52%, he'd passed two milestone thresholds—40% and 50%.
That meant…
Two draws.
He wasted no time and opened the first.
[Congratulations! You have obtained a (Modern Physical Exchange Voucher)!]
A useful one—but nothing new. He'd gotten that from the novice package.
Second draw—
[Congratulations! You have obtained the top-grade ninjutsu scroll: Lightning Release – Raikiri!]
"…Huh?"
Kai blinked.
Raikiri?
As in, Kakashi's Raikiri?
He immediately opened the scroll's details.
Ninjutsu Scrolls are divided into three grades:
Common: grants instant mastery of one ninjutsu.
Rare: same as above, with a moderate chakra boost.
Top-Grade: grants mastery, a significant chakra boost, and the relevant chakra attribute.
This one…
was top-grade.
Jackpot.
Kai's eyes lit up.
He was just thinking about how limited his chakra reserves were—especially compared to Madara's ridiculous output.
Even with his Rinnegan and teleportation authority,he still couldn't fully utilize his ocular powers without more chakra.
But now—
This scroll could change everything.
Without hesitation, he activated it.
The scroll disintegrated into glowing particles and merged into his body.
The next second—
A torrent of ninjutsu knowledge flooded into his mind.
The complete technique for Raikiri, plus its optimized taijutsu form.
And Raikiri wasn't just an S-rank jutsu—it was a close-combat assassination skill with terrifying penetration power.
It also required top-tier chakra control and speed.
In terms of execution, it was far harder than Chidori.
But he didn't care about that.
What excited him most—
Was the surge in power.
The system prompt updated his chakra nature.
[You have gained: Lightning Affinity]
[Your chakra capacity has significantly increased]
Before this, he only had two natures: Fire and Wind.
Now he had three.
And more importantly—
His chakra exploded upward.
It wasn't just temporary.It wasn't just cosmetic.
It was a permanent boost.
A true increase in the upper limit of his chakra pool.
His physical resilience had improved.
His spiritual toughness had grown.
Kai clenched his fist.
No more worrying about Rinnegan cost.
No more hesitation when activating special abilities.
He could now use Shinra Tensei freely—
Even test out a few new tricks with his Electromagnetic Force Field.
That included a higher-powered Railgun.
"…Can I blow up a small mountain now?"
He was eager to try.
But—just as he was about to run his next experiment—
He sensed movement.
In the distance, Madara had finished clearing the field.
And he was walking this way.
"…Guess I'll test it later."
Kai sighed and straightened up.
Time to welcome back the hero who had just annihilated a village.
