"It's a snowstorm again."

In the temporarily created cave, Art and a group of crows hid in it to rest.

Shaking his head, he calmed down and tried to observe his soul again.

Consciousness descended into the spiritual sea again, trying to pass through the majestic, rotating, never-ending spiritual whirlpool.

Much smaller than the spiritual vortex, the dark psychic vortex floats on it, with several thin black lines connecting the two.

If you want to observe your own soul, you need to cross the spiritual bridge with your consciousness and observe the soul hidden on the other side of the body.

According to Prome's explanation, the position of the soul is as follows:

"How should I put it, Master, look, this is a line, right? This is a hard square."

Prome drew a horizontal line segment and a square on the ground.

"If this line segment is a living thing, then it can only understand the direction in which it extends, which is the front and back direction, but cannot understand its up and down position. In other words, they only have two concepts of front and back, and no concept of up and down."

"As for this hard quadrilateral, it has the concept of up, down, left, and right, but it cannot understand the existence of height..."

It draws something that approximates a coordinate system.

"And this is..." Prome used the Mimic to transform into a cone, "This cone has three concepts: up, down, left, right and height..."

As Promi talked, a concept emerged in Art's mind - dimension.

One-dimensional line.

Two-dimensional surface.

Three-dimensional body.

“Let’s not talk about the method of construction through distortion for now.”

"To form a line segment, at least two points are required."

"To form a flat pattern, at least three line segments are needed."

"To form a three-dimensional object, at least four plane figures are needed."

"If there are five solids, it can form a four-dimensional body."

"I remember that a strong person at the fourth level of Apocalypse, whose body and soul are completely assimilated, needs to make a accumulation and breakthrough called "overlap"."

Art nodded. He had heard this knowledge from Duke Mercury, his mentor. This was one of the reasons why he felt that the civilization and technology of this world would be stronger than the original world.

This world has the means to upscale itself - overlapping and distortion.

Overlap - By superimposing substances, oneself can become a four-dimensional creature from a three-dimensional superposition just like line segments are superimposed into a plane pattern.

Distortion - through distortion, let yourself twist like a line segment into a circle, or a circle into a sphere, without superposition, twisting from a three-dimensional creature into a four-dimensional creature.

Powerful people above level four of Apocalypse are four-dimensional creatures.

It is not Minkowski's four-dimensional space-time view - Minkowski's four-dimensional space-time view is the fourth dimension formed by three-dimensional space plus time.

The four dimensions here refer to the four-dimensional space.

His original world, although technologically powerful and aware of the concept of dimensions, had not yet touched on dimensionality.

"But, what does this have to do with the soul?" Although he knew this, he did not understand what the soul had to do with it.

Prome scratched his head with his wings: "This overlapping process is overlapping with the soul as the center. The center of the five overlapping bodies is where the soul is, and the body is the body. This is the individual.

1. Therefore, it can also be said that the soul is on the other side of the body...and the spiritual vortex leads to this side..."

It was also a little troubled, not knowing what language to use to explain, so it organized the words intermittently.

After hearing its words, Art also reacted.

As three-dimensional creatures, they have the concept of length, width and height, which is the yz axis, so they can understand the length, width and height in a way that is compared with reality. If they are two-dimensional creatures, they can only have the physical concept of y coordinates.

The z-axis does not exist, and even though they can understand three dimensions mathematically, they cannot actually observe three dimensions.

In one dimension, there is no y-axis and z-axis, and it is impossible to understand two-dimensional, let alone three-dimensional, through actual comparison.

As a three-dimensional creature, although we can understand that there is a fourth coordinate axis, because there is no physical object of the four-dimensional body, we cannot understand the four-dimensional body through actual comparison.

Therefore, it is difficult to understand this concept even through imagination.

Fortunately, because as long as you pass through the spiritual bridge, you can reach the soul.

However, with Promi's guidance, Art's understanding of the soul has become stronger.

"The other side of the body...the other side..."

The concept was a bit abstract, but after he carefully visualized it, his consciousness slowly passed through the mental vortex, carefully passing through the middle, without touching the mental vortex, and without suffering the same sense of blockage as before.

.

When he touches the spiritual vortex, his consciousness will be swept to other places, appearing in other parts of the body, and sometimes even appearing outside the body.

But this time, his consciousness finally passed through the whirlpool and saw the soul.

It was...a faint blue, vague human shape, like a mist surrounding it.

The moment Art's consciousness came here, the soul opened its eyes and looked at him with empty eyes.

This action scared Art so much that he almost quit his meditative state.

Later, he discovered that this seemed to be an instinctive reaction of the soul.

Art breathed a sigh of relief.

At that moment, he even thought of the original owner of this body, the young man named Art.

Later, Art carefully observed the image of the soul——

Because it is impossible to measure it accurately, but proportionally speaking, my soul is about the same height as my previous life, which is the level of ordinary people.

His appearance is the same as that of his previous life, not with a high nose and deep eyes, but with a broad face, prominently protruding cheekbones and flattened cheekbones, with a medium root and not a protruding nose, typical Asian characteristics.

Because the whole body is blue and has a sense of darkness similar to psychic energy, the hair is also the same color - the eye sockets are even missing, there are only two holes, so there is no such thing as black hair and black eyes.

and......

There was also an extra eye on his forehead, and thin lines also appeared in other parts of his body.

With his crystal-clear, dark eyes, Art immediately thought of a name—Phantom Eyes.

Has it actually extended to the soul?

Frowning slightly, Art looked around his soul.

The mist-like spiritual illusion is surrounded by tiny blue particles like planetary belts.

Some of them were debris - Art suddenly remembered that he had seen these debris when he had just traveled through time -

This is the soul of the predecessor.

What remains are forty-seven light spots.

One is spherical, like a marble, and is brighter than other light spots.

Thirty-five of them are in the form of vague blue crows.

The last eleven remaining ones are in the form of red crows, the color of which is like lava. One of them is very blurry in color, even the shape of the crow is blurry, and it can only be barely discerned that it is a bird.

The number and color of the demonized crows reminded Art of the demonized crows, and the bright ball was Promi.

That blurry red color, if I am correct, is the demonized crow that died in the hunter's village last time.

So--

Art's eyes glanced at the blue crow light spot.

Among the many crows, a crow with the vaguest shape was flying around Art's soul together with other crows.

"Glora."

Art was silent for a moment, feeling relieved.

He did not contact Glora's soul.

Shaking his head, Art's consciousness came into contact with his soul.

In an instant, consciousness and soul are joined together.

A look of joy appeared in the empty eye sockets of the soul.

Art felt a strange lightness and an urge to float.

But he controlled the urge.

He has not forgotten that Promi said that the spiritual bridge is very powerful, but it is also very fragile. Without special spells, if the soul is moved casually, it can easily cause the spiritual bridge to collapse.

At that time, it won’t be that the soul has left the body, it will be truly dead.

Promi on the side also looked at Art who was meditating with some worry.

Most monsters use the power of the body and blood, and their power comes from the blood of the body.

Undead uses the power of the soul that has been infected by negative energy. The soul is the health bar and blue bar.
