The sight of the cat gazing up at the starry sky, weeping in sorrow, truly shook Chen Nuo.
He could understand the deep, undissolvable sorrow and helplessness in the Gray Catās eyes.
Originally, in Chen Nuoās understanding, he always thought this cat was as timid as a mouse...
Hmm? A cat as timid as a mouse? That always felt somewhat off...
Alright, he had previously thought that its withdrawal from the competitionāor as it put it, "forfeiting"āwas due to its cowardice.
It was only tonight, as the Gray Cat finished speaking, that Chen Nuo suddenly understood...
Aside from cowardiceāwhich may or may not have been trueāthere could also be "despair" and "hopeless frustration."
"...So, you think you wonāt succeed?" Chen Nuo lowered his voice.
"I donāt know." The Gray Cat shook its head. "I hope to succeed, but..."
After this "but," the Gray Cat closed its mouth and said no more.
"Alright, then letās change the question... What if you do succeed? I mean, *if*."
The Gray Cat still answered very frankly, "Donāt know."
Then it added, "We also donāt know what Four-Dimensional Life looks like or how it exists. So, how would I know? If success comes... that kind of thing is just impossible to imagine."
Thatās right. Lower-dimensional life cannot comprehend and imagine the existence of higher-dimensional life forms.
"Then talk about what you already know, or what youāve speculated," Chen Nuo said, shaking his head. "Youāve been busy for so long, through countless years and infinite strife. It canāt be that thereās been no progress until now, right?"
"Just as you said, your kind of Spiritual Life Form has already reached the pinnacle of three-dimensional life."
"Then you must at least know some things that we donāt."
The Gray Cat raised its paw towards the sky as if gesturing, then said, "I just asked you, what is life?"
"I answered, but you said it wasnāt accurate."
"Of course, itās not accurate. Three-dimensional life can only define three-dimensional life. However... itās not like we canāt speculate at all; there are always some avenues for imagination."
"For example, havenāt you humans always made many theoretical speculations about four-dimensional space?"
Chen Nuo did know something about thatāspeculations and hypotheses regarding four-dimensional space.
In fact, thanks to countless science fiction works from 20 years later, especially during the eight years of self-imposed isolation at sea, Chen Yanluo, who was bored out of his mind, had read all sorts of things to pass the time.
Simply put, the human conjecture about four-dimensional space is to add another dimension on top of the existing three-dimensional world.
A one-dimensional world is a line.
A two-dimensional world is a plane, meaning length and width, forming a planeālength and width are the two axes of the two-dimensional world.
The three-dimensional world, then, has length, width, and height, forming a volumetric solid world; thus, the three axes of the three-dimensional world are length, width, and height.
The so-called four-dimensional world is about finding the fourth axis based on the three-dimensional world.
As for what the fourth axis is, mainstream speculation and hypothetical theory suggest it is: Time.
Time!
A thought struck Chen Nuo, and he ventured, "The fourth axis of four-dimensional space is... Time?"
"It might be, or it might not be." The Gray Cat shook its head.
"What do you mean?"
Chen Nuo frowned, unable to understand.
Regarding the concept of four-dimensional space, Chen Nuo wasnāt entirely clueless; after all, many science fiction works discuss similar theories.
Time is the fourth axis of four-dimensional space.
Simply put: using Time as the axis, stacking numerous three-dimensional spaces on top of each otherāthatās what is called four-dimensional space.
But...
Next, the Gray Cat spoke with a smile.
"The so-called āTime,ā by your human definition concerning the material universe, is the manifestation of all material movement, change, continuity, and order. In other words, itās an abstract concept, but it can be observed and perceived."
"But this āobservationā and āperceptionā is also flawed."
"That is to say, this āperceptionā and āobservationā are also based on the material world, conducted under the theoretical framework of the āthree-dimensional world.ā"
"The problem is... just as when I asked you for the definition of life, you told me a great deal, but itās only the definition of life in the three-dimensional world."
"So, is Time really the fourth axis?"
"The definition of Time is: the continuity and regularity of material movement and change..."
"We live in a three-dimensional world, so our matter moves and changes. Thus, we define this movement and change with the concept of āTimeā."
"But the question is, does four-dimensional space really involve material movement and change?"
"Or, to put it another way, is the movement and change of material truly eternal?"
"You humans have gradually discovered many things; for example, the measurement of Time is not absolute but variable."
"For another example, āTimeā is derived from perception and observation."
"Furthermore, if thereās no perception and observation, the definition of Time almost becomes a Pure abstraction; it could be said to ānot exist.ā"
"Therefore, we had previously been convinced of treating Time as the fourth axis of four-dimensional space."
"But... as we venture further, we increasingly find that it may not be entirely so."
Seeing Chen Nuo frowning, the Gray Cat suddenly changed its approach. "Letās discuss an interesting, albeit very idealistic, claim concocted by one of your human philosophers."
"What is it?"
"You are a living being, right?"
"Of course."
"Good. So, letās assume you died."
"Then, two phenomena occur."
"To the world, you are destroyed."
"But to you, it is actually the world that is destroyed."
"Understand?"
"The so-called āworld,ā if seen from your perspectiveāthe nation, family, society... your friends, relatives, your emotions, feelings..."
"This mountain is very high, that sea is very wide, this cake is very sweet, that orange is very sour, this liquor is very spicy, that tea is very bitter..."
"These constitute the āworldā as defined from your perspective."
"From an individualās point of view, the so-called āworldāāor rather, our āthree-dimensional worldāāis an existence that you perceive and observe."
"Understand?"
"To you, a normal person, your world is illuminated."
"But for someone born blind, their world is dark."
"No matter how you describe or explain it to them, you can never make them understand what ālightā is; you can never make them understand what ābrightnessā means."
"So, the so-called āworldā is actually based on the perception of individual lives; the things you perceive form the āworldā you define."
"And once you die..."
"Chen Nuo, say at this moment, you suddenly died."
"Then to you, itās not that you have died."
"Rather, your āworldā has been destroyed. Your children, your woman, your friends, your family, your career, your nation, everything you know in this world... the moment you die, they perish, theyāre destroyed."
"...But it still exists; that is objective." Chen Nuo frowned. "Even if I die, the world still exists."
"But to you, this āindividual,ā you are destroyed because you died. You can no longer perceive or observe, so your world is destroyed." The Gray Cat smiled at this point. "From this definition... actually, the world perceived by each living individual is different."
"People born blind, deaf and mute, or color-blind..."
"Broadly speaking, you and these people exist in the same world."
"But specifically... from each of your personal perspectives, the world is different."
"So... Time is not the fourth axis of four-dimensional space?" Chen Nuo asked.
"No... based on our conjecture, Time is very likely the fourth axis," the Gray Cat answered again.
Chen Nuoās eyes widened.
"But this Time is not *that* Time."
"The Time weāve defined is the conclusion and definition made by three-dimensional life in the three-dimensional world. This is based on our range of observation and perception abilities concerning the changes and movements of three-dimensional materials in the three-dimensional world."
"In other words, the āTimeā we now speak of is, more accurately, āTime in three-dimensional space.ā"
Chen Nuo mostly understood what the Gray Cat meant.
The ālifeā defined by human beings, to be precise, isnāt the definition of life, but the definition of ālife in three-dimensional space.ā
Because we ourselves are three-dimensional life, we can only perceive and observe three-dimensional life; therefore, we can only define three-dimensional life.
Likewise, the āTimeā defined by human beings, to put it precisely, isnāt the definition of Time, but only the definition of āTime in three-dimensional spaceā! Because we, as three-dimensional life, can only perceive and observe Time in three-dimensional space! We can also only define the Time in three-dimensional space.
Perhaps... the āTimeā in four-dimensional space and our definition of āTimeā are different!
Chen Nuo pondered for a moment.
The definition of Time for humans, three-dimensional life, is the regularity and continuity of the changes and movements of āmaterial.ā
But... if the definition of āmaterialā in four-dimensional space differs from that in three-dimensional space, then the so-called Time would naturally have a different definition.
Chen Nuo could largely grasp this.
A line represents one dimension.
A plane represents two dimensions.
Then letās not talk about one dimension for now.
The material of a two-dimensional world (a plane world) is definitely different from the material of a three-dimensional world.
Then, the material of the three-dimensional world is most likely also different from the material of four-dimensional space.
Since the material itself is different, the concept of āTime,ā which is derived from observing the material of the three-dimensional world,
is very likely inapplicable to four-dimensional space.
Then, what defines the Time in four-dimensional space?
The continuity and regularity of the movement and changes of material...
Chen Nuo murmured to himself.
If the material is different, then how can Time be defined?
With what can it be defined? What else is common to both three-dimensional and four-dimensional space yet can also accommodate the criteria of movement, change... continuity, regularity?
Then, Chen Nuo suddenly took a deep breath and looked towards the Gray Cat.
The Gray Cat smiled. "Guessed it?"
The Gray Cat nodded. "Actually, this... is just our speculation, not necessarily accurate. After all, we havenāt succeeded either; weāve never reached the finish line, and no one knows what lies beyond that door."
Chen Nuoās expression became serious. "So... the fourth axis of four-dimensional space is indeed Time."
"But this āTimeā is different from the āTimeā we defined."
"The concept of Time we use, with āmaterialā as the observation target, isnāt applicable to four-dimensional space."
"According to your conjecture..."
"The definition of āTimeā that meets the standards of four-dimensional space isnāt measured by āmaterial.ā"
"But by..."
"Life!"
Every individual life perceives the world differently.
Theoretically speaking, countless lives equate to countless worlds and countless three-dimensional spaces.
Stacking these countless three-dimensional spaces, using lifeās Time as an axis, creates what is called four-dimensional space.
This was the meaning the Gray Cat wanted to express.
This ālife Timeā isnāt about how many years or days a life can live...
Itās a different meaning.
"To put it simply, itās about the birth and extinction of individual lives. That is, the āmovementā and āchangeā in the definition of Time."
"Every life has a birth and an extinction; this constitutes continuity and regularity."
"This is the āTimeā measured by life."
"The āTimeā of four-dimensional space."
The Gray Cat shook its head. "Coming up with this speculation and hypothesis was the guess of our kind of Spiritual Life Forms. As before, we donāt know if itās right or wrong..."
"It could be correct."
"But the greater possibility is that itās wrong. If it is wrong, then the ultimate result is that we put all our effort into running in this directionāsearching, evolving."
"In the end, we may find that what awaits us isnāt the finish line of successful evolution, nor the door that leads us out of three dimensions to reach four dimensions."
"It might be a dead end, an iron wall."
"But... regardless, with everything we currently possessāall the power we hold, the position we stand ināwhat we can see, summarize, and speculate... thatās all there is."
Yes, itās a hypothesis.
But considering the height of the ecological niche occupied by the Mother civilization and the Seeds, they are clearly already above humanity.
To use their own words, they are at the peak of three-dimensional life.
Then, perhaps, their speculations are closer to the real answer than current human hypotheses?
"So, here comes the question."
"If the fourth axis of four-dimensional space truly is Time."
"If the definition of Time in four-dimensional space is measured not by āmaterialā but by ālife.ā"
"Then..."
"Back to my initial question."
"Chen Nuo..."
"What is life?"
"Or let me put it another way."
"Where does life come from?"
Chen Nuo was speechless.
Where does life come from?
This question...
He suddenly remembered a saying.
Humans are born of their human mothers; demons are born of their demon mothers.
Whatās your motherās surname?

Authorās Note:
Firstly, I, Pang Wu, studied liberal arts, so all these concepts are bits and pieces Iāve encountered while reading and researching, then mixed with my own imagination. To put it bluntly, itās less scientific than pseudoscience! To my brothers and sisters who are actual science students, especially those in physics and theoretical physics, please donāt laugh at me; this is merely a novelistās imagination.
Secondly, I know these last two Chapters have been heavy on conceptual explanations. However, in a novel spanning over two million words, some Chapters are inevitably needed to lay out the worldview and fundamental settings of the story. Iāll try my best to simplify these explanations while still making them as clear as possible. Such Chapters are necessary.
Thirdly, this book isnāt science fiction. As a "pseudoscientist among pseudoscientists," Iām not capable of writing hard sci-fi. Iām merely borrowing some concepts to help build a logical framework for the setting.
Thatās all.
Tomorrow is the New Year, so Iād like to wish everyone a prosperous Year of the Tiger in advanceāmay you all be full of vigor and vitality!
