"So, how should I locate the other end of the bridge in the alternate dimension?"
Qingshui asked Boros.
"Let me put it this way, do you know the concept of topology? When we normally use spatial teleportation, it's a representation of spatial topology within the four-dimensional spacetime we inhabit. Extending this to higher dimensions, if I were to explain it scientifically, it would probably be... uh, what was it, something about turning strings into membranes?"
Blast scratched his head, trying to find a suitable explanation. However, due to his slightly lacking scientific literacy, he understood the theories and processes involved but couldn't articulate them clearly.
Fortunately, Qingshui possessed sufficient scientific literacy and understood space.
"Quantum field theory of topological invariants,"
Qingshui said, looking at Blast.
Blast's expression went blank: "Huh?"
He had studied some related scientific knowledge to better grasp and systematize his spatial abilities, but it was all relatively easy-to-understand introductory concepts, nothing too deep.
He was the number one ranked S-Class hero, and he had been active as a hero for over twenty years. He also had to expend a great deal of energy fighting gods, rather than scholars who had undergone extensive professional study and scientific research.
But now it seemed...
Did this person in front of him know his stuff?
Qingshui explained:
"This is a method used to summarize metrics of certain related functions that are independent of the background spacetime manifold. It can be applied to the topologicalization of higher-dimensional spaces, achieving higher-dimensional topological excitations.
As is well known, String-Net Liquid is a universal theory of topological order. In five-dimensional space, strings are uplifted to membranes, but their excited states can still be calculated using mathematical tools."
Blast rubbed his head.
As is well known?
Then why didn't he know?
Didn't opening this portal just involve using his spatial abilities, doing this, then that, and finally this?
He felt an itch on his scalp, like his brain was growing.
Seeing Blast's reaction, Qingshui knew he wasn't very knowledgeable in this area of science.
It was like how ancient people could summarize many natural laws and apply them, but they lacked a systematic method to study and explain the underlying principles.
However, to modern people who had mastered scientific methods and possessed a certain amount of scientific knowledge, most of these natural laws could be explained scientifically.
After Blast revealed these things to him, Qingshui could use his own scientific knowledge to better understand, learn, and utilize them.
Of course, Blast's lack of understanding didn't mean his foundation in spatial abilities was weak. It was just that their deconstruction and manipulation of space belonged to different systems due to their respective cognitions and ways of thinking.
One was perhaps the practical, experience-based type, and the other was the theoretical, academic type. There was no inherent superiority, and their upper limits were essentially infinite.
It was just that the former could learn and apply more easily with talent, while the latter had a more stable lower limit.
"Simply put, it's about using mathematical tools and physical models to calculate the excited state of five-dimensional spacetime in the real dimension. In layman's terms, it's about finding the part where the real world overlaps with higher-dimensional space. That part is a membrane composed of countless strings.
And this membrane is the 'boundary' of real space. It's not a membrane in an absolute physical sense, but rather it's omnipresent, hidden in the inner layer of every inch of space. As long as we make the bridge pass through this 'boundary,' we can travel to an alternate dimension."
"That's right, the process of actually operating it can indeed be described abstractly like that."
Blast nodded, then took out an exquisitely crafted, faintly glowing white metal sphere and handed it to Qingshui.
"The alternate dimension is vast and infinite, without boundaries. However, we are breaking out from this world, so the location won't be too far. This Phase Sphere stores the location of one of our team's strongholds in the alternate dimension. By the way, with your physical condition, you should be able to survive in an oxygen-deprived vacuum, right?"
"No problem."
Qingshui took the white metal sphere and replied to Blast.
Once one's energy level reached a certain point, as long as they could achieve internal energy self-circulation like circulating Qi, they could survive in an oxygen-deprived vacuum.
Not to mention, Qingshui's Black Samurai Armor had a life support system, and Qingshui could also activate the third level of Reverse Growth, transforming himself into an energy-based lifeform that didn't need to breathe.
"Then let's give it a try. I'll go ahead and wait for you."
Blast extended his hand, opening a portal in front of him. He stepped through and disappeared.
Qingshui stood in place and thought for a moment, then reached out his hand forward.
"Buzz!"
A portal, imbued with mysterious colors, opened before him.
Qingshui smiled slightly and stepped through as well.
Success!
...
...
"Success!"
Naruto World.
Qingshui stood in a void, looking at the vast, boundless, semi-transparent membrane before him, which could seemingly contain everything.
This was the alternate dimension, specifically the alternate dimension of the Naruto World.
The infinitely large semi-transparent membrane before him was the overlapping part that separated the real world from higher-dimensional space.
It looked like a membrane, wrapping the entire world.
It was like the intersection of a plane and a line.
Either they were parallel and didn't intersect, or they overlapped, with the line being part of the plane, but this was only in extremely rare cases, with a probability close to zero.
Most of the time, the intersection of a line and a plane was a point.
That is, the intersection of two and three dimensions was one dimension.
The real world had the passage of time, making it a four-dimensional world. If the intersection of the four-dimensional world and the higher five-dimensional space was three-dimensional.
In other words, this membrane was not a purely conceptual two-dimensional plane, but a three-dimensional physical object.
Theoretically, the membrane was as large as the world, almost infinite.
Even Qingshui couldn't see its edge at a glance.
This was a gap in dimensions.
A one-dimensional being might be able to see lines, perceive planes, or even higher-dimensional three-dimensional objects, because they were already overlapping parts of them. But they absolutely couldn't see the entire plane, the entire three-dimensional object. The gap was greater than a fish measuring the ocean with its eyes.
Unless Qingshui could also elevate himself, becoming a five-dimensional being like a multiversal god, making himself an existence equal to this entire world.
"It seems my guess was correct. Kamui Dimension, Starting Ball Dimension, Mahakala, Amenonaka—these spaces are actually extra-dimensional spaces semi-independent of the Naruto World."
Qingshui's gaze fell upon the small bumps on the thin film, his eyes filled with scrutiny.
These small bubbles were extra-dimensional spaces that existed by attaching themselves to the entire Naruto World. Because the Naruto World was a complete world with immense mass, these tiny extra-dimensional spaces were captured by its gravity and attached to the Naruto World.
Of course, while they were called tiny, the actual spaces were quite large.
Should he go in and take a look?
A thought flashed through Qingshui's mind, and then he created two Shadow Clones.
The two Shadow Clones exchanged a glance, then simultaneously reached out and opened portals in front of them.
"It seems that without coordinates, forcefully breaking through the dimensional membrane and locating the space within will consume a lot of energy. And this isn't even a real world, just two extra-dimensional spaces.
However, if I can leave definite coordinates within the boundary, it should significantly reduce energy consumption, equivalent to having a key. What I'm doing now is like smashing the door to get in... no, it's more like picking the lock."
Qingshui's thoughts churned, while the two Shadow Clones, after consuming a large amount of energy, had already entered.
"Where is this..."
As the Shadow Clone stepped through the portal, the first thing that greeted its eyes were vast expanses of messy, square stones.
The sky was dim, but it seemed to emit a faint light, relying on the energy possessed by the extra-dimensional space itself.
The entire space was filled with stones and nothing else.
However, the area was indeed quite large, enough to store quite a few things.
"Could this be the Kamui Dimension?"
Qingshui quietly surveyed his surroundings, then flew into the sky, fully releasing his senses to observe the entire space.
It looked quite similar.
It could be used as a temporary storage space.
But besides that, it seemed to have no other use, let alone whether there were any living beings within it.
However, the conditions for life were very harsh, and Qingshui didn't believe that life would exist in such a space.
"I wonder where the other Shadow Clone went."
Qingshui silently looked up, reopened the portal, and walked out.
With the dimensional membrane blocking the way, directly dispersing the Shadow Clone here would most likely prevent it from returning to the main body.
On the other side.
The second Shadow Clone had entered the largest extra-dimensional space within Qingshui's line of sight.
What surprised Qingshui was that there was almost no physical substance here, and the gravity was extremely low.
Besides a few floating stones suspended in mid-air, there were spheres of silent light. However, a very small number of these spheres occasionally emitted waves of thought.
Through the light spheres, one could vaguely see transparent human bodies with their eyes closed.
"These are... souls! And they are the souls of extremely high-quality powerhouses, being nurtured by the Chakra contained within these light spheres."
Qingshui narrowed his eyes slightly, his gaze sweeping across the boundless space.
A rough estimate showed that there were at least several thousand souls appearing before him, and further in the distance, there were many more.
The soul strengths varied, but they were generally far beyond ordinary people, with a few exceptionally strong individuals.
Undoubtedly, these people were ninjas in life, and their souls were sealed here after death.
In the high sky, new light spheres containing souls occasionally descended.
"I suspect this is the legendary Pure Land. I wonder if my arrival will attract the attention of the Sage of Six Paths and Hamura Otsutsuki."
Qingshui became vigilant in his heart, continuing to traverse the boundless space, while also striving to release his senses to probe his surroundings, including those light spheres.
He didn't recognize any of the souls here, but through the subconscious manifestations of their clothing, he could tell that these people were at least from several hundred years ago. Furthermore, some of the souls' clothing bore the crests and patterns of ninja clans such as the Senju, Uchiha, Uzumaki, and Hyuga Clan.
Qingshui continued to ascend, looking at the newly added light orbs in the high sky.
As expected, many of the souls here likely belonged to ninjas who died in the ongoing Fourth Great Ninja War.
After searching for a while, Qingshui also found Kitsuchi's soul.
This was enough to confirm that this place was indeed the Pure Land.
Moreover, Qingshui made a new discovery here.
A giant being with two horns on its head, ragged clothes, and a ferocious face flew in the sky, constantly splitting into countless clones and traversing space in a bizarre manner, passing through the dimensional membrane.
This dimensional membrane was riddled with holes, as if it had been modified by some powerful entity. It directly connected to the dimensional membrane of the Naruto World on a spatial level, allowing souls to easily travel between the two worlds.
It seemed that the entity above was the Shinigami, capable of splitting into clones to collect the souls of the deceased in the Ninja World.
Besides the Shinigami, Qingshui also saw another specialty of the Pure Land.
The King of Hell.
The creature that looked like a gate to hell, but there were many of them here, and they didn't have Rinnegan.
With Qingshui's vision, he could easily tell that these Kings of Hell were merely existences with simple, fixed programs. They were a type of puppet that differed greatly from the mainstream existences in the Ninja World and could be manipulated by a certain specific high-level energy.
It was likely the power of the Rinnegan.
The Shinigami also didn't look like a normal creature. Although it seemed to possess some degree of self-awareness, it was quite slow. It was likely created by the Sage of Six Paths using Yin-Yang Release.
Perhaps not even Yang Release was used, as the Shinigami was a pure spiritual being without a physical body.
"It seems knowing this is the Ninja World doesn't help much, but that's not necessarily true. Tobirama Senju and Orochimaru can casually pull souls up here for Impure World Reincarnation, and the Sage hasn't come out to cause trouble. As long as I don't take too many souls at once, it should be fine."
Just as Qingshui was contemplating the purpose of the Pure Land for him, the space in front of him suddenly distorted.
From a black Portal, the figure of an old man appeared, clad in a white robe adorned with magatama, with horns on his head and Truth-Seeking Orbs floating behind him.
The most striking features were the nine-red-magatama Rinne Sharingan on his forehead and a pair of deep, mysterious Rinnegan.
"Sage of Six Paths..."
Qingshui softly uttered the identity of the newcomer.
"It seems you recognize me. Good, I am the Sage of Six Paths, Hagoromo Otsutsuki. I never expected that after a thousand years, a descendant would be able to send a clone into the Pure Land and awaken me."
The Sage of Six Paths sized up Qingshui and spoke.
"Awaken? It seems Senior Hagoromo, you have refined this alternate dimension into your own space. Was my entry process too rough, thus attracting your attention?"
