I walked over to Wu Lin and sat down, Wu Lin looked at me: "Can't sleep?" ”

"I'm not tired, I'm not sleepy." While talking, I took out the lighter from my pocket and handed it to Wu Lin: "Are you used to smoking cigars?" ”

Wu Lin took a little effort to light the cigar, raised his hand again, carefully looked at the uniform spark on the top of the cigar, and said to me: "The taste of this thing is very special and intoxicating, but it is not as choking as ordinary cigarettes, and the feeling of smoke stirring along the tongue is very interesting." ”

I lay on my back and half leaned on it, lit a cigarette, and took two long puffs of smoke, Wu Lin said beside me: "A physique like yours shouldn't be addicted to nicotine, right?" ”

I smiled: "It's really not, it's just that I'm used to smoking, and I always feel uncomfortable without holding something in my mouth, which should be considered an addiction." ”

After saying this, I paused for a moment, and then said to Wu Lin, "Thank you." ”

Hearing this thanks, Wu Lin suddenly became a little unnatural, but he still said, "Thank me for what?" ”

I said, "Thank you for taking care of Li Huaishan for me just now." ”

Wu Lin frowned and didn't speak, but in his eyes, I saw a hesitation, or a contradictory brilliance.

Maybe he couldn't tell why he wanted to help Li Huaishan when he was in the tunnel just now.

I was silent for a long time before I took the initiative to speak: "Wu Lin, can you tell me, what exactly is the quadruple space?" ”

Wu Lin sighed: "Actually, I can't say it clearly, the old pedant didn't give me the answer, he said, there are some things that I can't understand when he says it, and I have to explore and experience it myself." In the early years, I had been confusing the quadruple space with the quadruple dimension, but the more I saw it, the more I felt that the quadruple space should be a product of the third dimension, but it took longer than the formation of the double-layer star. ”

I smiled helplessly: "The more I say it, the deeper it gets, I don't understand." ”

Wu Lin: "You shouldn't be unintelligible, in fact, your understanding of the fourth dimension is far deeper than mine. ”

I looked at him with some curiosity: "What do you mean by that?" ”

Wu Lin: "A few years ago, in order to explore the root of the fourfold space, I studied a lot of books related to people like you. In one of the books, I saw a very interesting point of view, the book said that the so-called cultivation of immortals is actually a means for human beings to jump to the fourth dimension, those immortals who have left the physical body and have been feathered, in essence, have broken away from the third dimension and become a special life form in the fourth dimension, and this kind of thing may only happen on the earth, and it is unlikely that immortals will appear on other life planets. ”

I didn't open my mouth as he spoke, and although these theories seemed to me to be completely beyond reality, I listened with great interest.

I have to say that Wu Lin's views will indeed subvert my understanding of the world to a certain extent.

He said that the reason why the earth is unique is that the planet we are on was originally a double star, that is, this planet is a combination of two planets that can give birth to life.

Everyone knows that there are nine planets in the solar system today, but in ancient times, there were originally ten planets in the solar system, and the one that disappeared was called "Theia".

Due to the fact that Theia's orbit is very similar to that of the Earth in ancient times, due to the change in the energy of the sun's inner core in the process of fusion, the gravitational attraction to the surrounding planets has gradually changed over the years, which has led to the intersection of the Earth and Theia's orbital path, and the two planets have collided once in the distant years before human beings appeared.

The Earth crashed into Theia's crust and shattered the asteroid, most of which were gravitationally combined into a new star after billions of years, which is the Earth as we see it today, and the remaining small fragments formed the Moon, the only natural satellite of the Earth.

During that violent impact, some of the star fragments broke out of the third dimension under the huge concussive force and entered the fourth dimension, which was originally undetectable to humans, which also led to the formation of some kind of connection between the Earth and the fourth dimension, and the same is true for the Moon.

Wu Lin said that in our circle, the reason why the moon is particularly special compared to other stars is not only because the moon is closer to us, but also because the sunlight will show a special energy that does not belong to this world after being reflected by the moon.

This also seems to explain why most evil creatures are afraid of sunlight, but they can thrive on the nourishment of moonlight essence.

In addition, Wu Lin also said that the so-called Lingyun and the so-called Qi Field should not exist in our world in the first place, because except for cultivators like me, no one else can perceive their existence at all.

Anything in the third dimension should be sensed normally by the beings of the third dimension.

Even the magnetic field that cannot be seen with the naked eye can be detected by scientific and technological means, but the Lingyun and Qi fields seem to only exist in the minds of cultivators, and no scientific and technological means can detect them.

Wu Lin said that the reason for this situation is that all things in the fourth dimension are far beyond the limits of common sense for the life forms of the third dimension, and they cannot be measured by the "reason" in reality.

As for ghosts and spirits, to put it bluntly, they are just metabolites of the fourth dimension, and they can't be killed by normal means, only we, the cultivators, can use the power attracted from the fourth dimension to eliminate these spirits.

Later, he talked about the quadruple space, and in his opinion, since the quadruple space appeared on the earth and could continue to exist steadily for a long time, it means that it can only be a product of the third dimension, and Wu Lin also has his own views on its cause.

He believes that even if the quadruple space is not a product of the fourth dimension, it must have been affected or distorted by the fourth dimension, and this space should be located at the point of impact between the earth and Theia, and the violent collision not only causes this space to be squeezed and distorted, but also causes the energy of the fourth dimension to be immersed in it, and only in this way can we explain why the time sequence and physical space in the quadruple space are very different from the real world.

Hearing him say this, my brain circuit has been completely deviated by him, and at the end of the question: "Is the earth the only binary star in the universe, it is said that the collision of two stars should occur often in the universe." ”

Wu Lin: "Astral collisions are indeed very common, but in order to make contact with the fourth dimension in an impact, the chance should be very low. How to put it, this probability is like a person being struck by lightning 10,000 times on a sunny day...... Not hurt yet. In short, the probability is low to infinite, approaching zero. Also, I coined the word binary star myself. ”

I smiled and asked him, "Did you find these things from somewhere else, or did you come up with them yourself?" ”

Wu Lin didn't answer my question, but asked me rhetorically: "Have you ever thought about why human civilization has developed to the extent it is today, and why in the long years since the emergence of human beings, there has never been a huge disaster on the earth that can wipe out human beings at one time?" ”

I didn't take what he said seriously, and still smiled: "Because of luck? ”

Wu Lin said: "The fact that human beings have been able to evolve and develop safely so far is also a small probability event and an accident...... But have you ever thought about it, is this really an accident? ”

I said: "This should not be accidental, I think that the development of human beings may be in line with the principle of the cycle of heavenly principles, anyway, human beings, as a species, will still perish one day, even if they do not perish, they will evolve into completely different life forms, this is also part of the cycle of heavenly principles, no matter what, nothing is immutable." ”

Wu Lin waved his hand: "I don't understand the set you are studying, but I always feel that maybe in the fourth dimension that we can't reach, something has been staring at us, and the human race has been able to develop safely until now, because of it, or it is the heavenly principle in your mouth." If you think about it, our world is actually like a computer program, and each value has its own extreme, as if it is artificially defined. ”

I really didn't understand what I said, so I asked, "What do you mean?" ”

Wu Lin asked me, "Do you know absolute zero?" ”

I said, "Yes." ”

Wu Lin: "Have you ever thought about why the theoretical minimum temperature in thermodynamics can only drop to minus 273.15 degrees Celsius, which is like an invisible wall, limiting the temperature value to a fixed range." ”

Wu Lin's words made me feel a great fear in my heart, and at that time, I felt as if there was really a huge eye looking down on us in the dark starry sky.

When this thought came to me, I forcibly diverted my attention and tried to think of something else.

I don't want to take these things that Wu Lin said, and I don't dare to take them seriously, because it will make me feel that my life is meaningless, and all the struggles in the savage mountains seem so futile.

Probably seeing that my face was not very good, Wu Lin also sighed: "The more I study these things, the more frightened I feel, and I don't know whether these conclusions I have reached so far are true." So I had to find the quadruple space, and my intuition told me that there must be the answer I was looking for. ”

I smiled helplessly: "I feel that my outlook on life is about to be subverted by you, and I knew that I shouldn't have known you in the first place." ”

Wu Lin also showed a rare smile on his face: "Even if you don't want to know me, I will go to you, no matter what, in this world, I only have you as a kind." ”
