"After people die, their souls just come to a place like this to freeze, stuck for who knows how many millions of years? That's just too cruel, isn't it?"
Sora complained.
In fact, his mention of 'millions of years' might even be an underestimate, considering the lifespan of a planet!
It's highly likely these people would remain frozen like this until the very end of the planet's life!
"What is the Underworld King here even doing?" Sora complained again.
In the Soul Society, there's a concept of balance between the three realms and reincarnation, but here in the Naruto World, it seems completely absent!
'But the Naruto World does have the concept of the Six Paths of Reincarnation, doesn't it?'
'Could it be that there really is no Six Paths reincarnation here?'
However, this thought had just surfaced when Sora cut off his own speculation.
'No, that's not right!'
'After all, Indra and Asura have been continuously reincarnating!'
'Putting aside the fact that they are both sons of the Sage of Six Paths, the fact that they can reincarnate means this world has the mechanism!'
'So there's no reason these people couldn't reincarnate, instead being stuck here frozen!'
'There must be something peculiar about this!'
Having realized this, Sora's thinking broadened.
He flew into the air again, blew away more layers of ice, and observed more people!
And then he discovered the commonality among these people.
All the people in the area near Sora were Ninja, because they all wore forehead protectors!
As far as Sora's eyes could see, he couldn't spot anyone who wasn't a Ninja!
"So, the Pure Land of the Ninja World only freezes the souls of Ninja?"
"Emmmmmm..."
"That... actually seems somewhat logical! Just a bit messed up!"
Sora shook his head with a sigh.
The Ninja who strutted around proudly in the world above, who among them knew that after a lifetime of swagger, they would end up frozen here?
Based on this hypothesis, Sora expanded his reasoning.
"So, this Pure Land is actually some kind of defense mechanism of the Ninja World's planet?"
"Because the God Tree is an outsider, the Chakra Factor it brought infected the natives, turning them all into... well, let's say 'plant-people'."
"And my research, plus the original work's setting, shows that Chakra follows a person's soul."
"So, to prevent these contaminated people from continuing to spread contamination, the planet directly froze their souls here?"
"If the souls are frozen, that means their Chakra can't spread out either?"
Sora inferred.
This explanation was somewhat reasonable.
After all, the God Tree could instantly absorb the Chakra of the entire world, and the person who ate its fruit was called the Progenitor of Chakra.
And Chakra is also synthesized from physical energy and spiritual energy, which come from external sources like food and drink.
So, by extension, Chakra grows by absorbing the planet's energy.
But then Sora thought about it and realized this explanation might also be wrong!
Because since the end of the Warring States Period, as Ninja shifted from clans to villages, their numbers kept increasing.
Later, in the Boruto era, when scientific ninja tools became widespread, Chakra would probably become something everyone possessed.
It's like the neural interface in a Cyberpunk Worldview.
If one doesn't have Chakra, they can't really use Chakra-based scientific ninja tools well.
So, even if they don't have Ninja Talent, they'd still likely refine a little bit of Chakra.
Therefore, the amount of Chakra on the surface was increasing.
Even if the planet was constantly sealing it away, it wouldn't make much difference to the outside world.
And simultaneously, there was another key flaw in the 'planet' theory!
That was the current situation outside: the dead revived by Edo Tensei were marching across the land!
If it were the planet's seal, the souls of these Edo Tensei individuals simply couldn't return to the surface!
Thus, thinking up to this point, Sora summarized.
This place was not the handiwork of the planet.
Then...
"It must be the work of a person!"
"The Sage of Six Paths!"
Sora confirmed his judgment!
If the one who selectively and specifically froze Ninja's souls was the Sage of Six Paths...
Combined with the later event where he summoned the previous Kage to request Chakra Assistance, Sora began to understand!
This entire Pure Land was an army prepared by the Sage of Six Paths for the extraterrestrial threat!
Just like his mother tirelessly prepared the White Zetsu Army to face her original clan!
"Hiss!"
Upon realizing this, Sora drew a sharp breath!
'What a grand scheme, truly a grand scheme. If his speculation was correct, he couldn't help but admire the sheer scale of the Sage of Six Paths' plan!
Because if viewed this way, then all the circumstances of the Ninja World, the current state of war, even future crises, and the existence of Black Zetsu, were all permitted by the Sage of Six Paths!
After all, if there was perpetual peace, why would the various countries need Ninjas?
Ninjas grow stronger through battle and slaughter!
Only through constant fighting, fighting, and more fighting, could the massive Ninja Population produce super-powerful individuals like the First Hokage and Uchiha Madara!
And viewed this way, Asura and Indra were also pawns of the Sage of Six Paths!
