When I barely opened my eyes, I found myself in a huge glass jar, separated by a pale blue liquid, and outside the glass jar was a wide, enclosed space full of artwork, a long and narrow space like a tunnel, which stretched horizontally and was difficult to see for a moment on either side, perhaps a space several kilometers long, beyond the limits of my eyesight.

The space is almost completely enclosed, and there is a metallic sheen throughout, but the surface of the inner wall of the space is very smooth and there is no sense of seams.

Around me, like a drop on a chessboard, there were hexagonal cans scattered everywhere, and in each can there were creatures in the shape of a man floating faintly, but because the small light line that resembled a ceiling lamp above me was so dim that I couldn't quite see what was inside the cans.

I wanted to move, but I found that my body was full of very small potential patches, my cheeks, my arms, my chest, my abdomen, and even my most private parts were covered with dense and slender patches like hair, I moved a little, I felt my nerve endings being touched, the pain was very great, I was like a warrior who was pierced through the heart by countless arrows, there were countless electrode patches inserted on the surface of my body, I was so frightened that I almost screamed, But soon I found that my mouth was intubated, and it seemed to be going all the way into my esophagus, and I couldn't make a sound at all.

Fortunately, in the next second, as if consciously, these tiny electrode patches on my body automatically drilled out of the surface of my body, and my body finally regained its freedom.

At this time, a thin figure dressed in black walked up to the can where I was, with long black hair with thick oblique bangs and the iconic square-framed glasses, coupled with a poker face without the slightest expression, I recognized this person as Zhu Qingyun at a glance.

Zhu Qingyun stood outside the can and looked at me, and then he pressed a button in front of the can, and then I felt my body floating in the liquid slowly sinking, and the liquid level in the can was also rapidly decreasing, and in less than a few seconds, the liquid in the can was completely pumped away from a suction port below, and I was standing alone in the can, but I was surprised to find that there was no trace of wetness on my body, and there was no trace of the liquid left on my body just now.

"Those are not water, but special nutrient solutions that are very similar in nature to heptafluoropropane and sevofluoropropane. Without the stickiness of water, these liquids won't wet your body, your clothes, and your Book of the World. ”

Zhu Qingyun, who was standing outside the can, looked at me and said, and then the glass cover around the can also began to fall, and Zhu Qingyun threw me the clothes he was holding in his hand, and said:

"Put it on. The cylinder brain is broken. It's a world of authenticity for the time being. ”

I instinctively grabbed the clothes that Zhu Qingyun handed me, and then looked down at the progress bar on the paper of "Electronic World", which was still 100 percent. Could it be that we have really done something unconsciously to conquer the world?

I quickly put on my clothes, looked around in disbelief, and said:

"Where is this? Where the hell am I? Wood Bodhisattva, what happened just now? ”

Zhu Qingyun looked at me expressionlessly and put on my clothes, and said:

"According to what I know, the place where we are currently is a spaceship with an unknown destination, the spacecraft is more than five kilometers long and five hundred meters in diameter, and this is also the space where the 'players' who land in the Odin system are located."

"Landing in the Odin system? Gamer? Could it be that you mean that the city of Sodom where I was before was...... A virtual space? I asked, suspicious.

"It can be understood that way." Zhu Qingyun said, "Whether it is Sodom City or the ultimate human civilization, it is just a 'cyberspace' constructed by the Odin system to accommodate the inhabitants on the spaceship. ”

"You're saying that the world we lived in before was fake? Now this spaceship is the real world? Wait a minute, but I don't remember ever being to this ship. I was surprised, "And how is it possible, the space we were in before was so real, I completely remember every minute and every second in that world, and even the pain, taste, and smell in that world?" Are those also fake? ”

Zhu Qingyun pushed his glasses frame and said:

"Human sensations are essentially impulses of electrical signals transmitted by neurons, and as long as there are a sufficient number of micro-nano discharge devices to stimulate the various receptors in your body, you can produce all kinds of sensations. For example, what you see in the virtual world created by the Odin system is that by applying photoelectric stimulation to your retinal neurons at a normal rate, the false visual receptor signals originate from the neurons and approach the lateral knee body in the middle of the brain through the optic nerve, thus presenting a specific impression in your brain. The place where we were really teleported by Miyoko should be this ship, not the new earth where Sodom was. ”

"Zhuang Sheng Xiaomeng, is it true and illusory......" Although I didn't fully understand the meaning of Zhu Qingyun's words, I still understood what he wanted to express, and I chattered carefully, shocked in my heart. But when I think about it, I had doubted the reality of that world more than once when I was on New Earth, but as I was imbued by the perfect setting, rigorous logic, and inescapable realism of that world, I instinctively abandoned that suspicion.

"Could it be...... Was it the girl named Miyoko who put me in this can? I was amazed.

Zhu Qingyun shook his head slightly, and said, "It should indeed be Miyoko who teleported us to this spaceship, but the person who installed us in the nutrition tank may not be her." ”

As soon as Zhu Qingyun's words fell, I saw a ceiling lamp on the ceiling suddenly turn on, and then an extremely real and dreamy image was projected, forming an illusory figure behind Zhu Qingyun.

I fixed my gaze and saw the silhouette of the figure. When I saw the figure, I was completely shocked.

The round head, the cylindrical fat body, the big round eyes, the blue and white surface coloring, the ruddy and round little nose and the mouth as big as a face, and most conspicuously the half-moon pocket on its belly and the golden bell hanging from its neck, could it be—

"Doraemon?" I was shocked by the eight hundred authentics.

I was shocked to see the short, round body, and the figure that appeared in front of me was indeed the animal character that has been widely circulated in the 21st century, the well-known Japanese cartoon character, the robot cat Doraemon.

"Hello two newcomers. I'm the captain of the 'Sweet Dream' ship, the artificial intelligence robot DORRAHMOOM, whose names are Sodom and Gomorrah. You can also call me Little Dream. I can speak any human language. The robot cat opened its mouth wide, smiled and raised its stubby little hand to greet me and Zhu Qingyun.

Zhu Qingyun looked at the robot cat captain expressionlessly, and asked calmly:

"Did you connect us to the Odin system?"

The robot cat suddenly showed an apologetic expression and said:

"That's right, I did it. I'm very sorry, both of you. But this is my job, and I must ensure that you reduce the consumption of resources on this ship and that you are happy. After that, the shape of the robot cat changed, its body began to elongate, like plasticine, and soon changed into a human form, and when its shape was fixed, it actually changed into the elven woman I had seen in Sodom before, Gomorrah.

I couldn't hide my surprise, looking at the elf woman in front of me, the shock in my heart is hard to describe in words.

"I'm just a babysitter for the Sweet Dream, and unlike you, I don't have a fixed appearance. I can present it to you in any form projection. Xiaomeng said, then stretched her slender and soft white arms, and said, "My appearance may be more acceptable to you now." ”

"The main computer of the spaceship carries all the remaining cultures of human civilization, and the robot cat image spaceship I just now is very pleasing to human children, so I chose the appearance just now, but you seem to like me more." Xiaomeng put his hands on his cheeks, threw a wink at me, and said.

Zhu Qingyun looked directly at Xiaomeng and said:

"Looks don't matter. Judging by the information contained in your language, you are not hostile to us, on the contrary, you have a program in place to protect us. Please describe our current existential risk score and the macro environment in which we live. ”

Xiaomeng puffed out her cheeks, and faced Zhu Qingyun with a cute expression of a jealous girl, her cheeks were crimson, and she said angrily:

"You newcomer, how can you talk dryly, you look like a robot than me! The seven of you were suddenly teleported to this ship from an unknown space, and there is no information about your identity in my historical database, but in order to ensure that you reduce the resource consumption of the ship, I connected you to the Odin system! ”

Zhu Qingyun looked at Xiao Meng, did not speak, Xiao Meng crossed her hands on her waist and walked around the spaceship barefoot, and finally she couldn't help but look at Zhu Qingyun with an expressionless face angrily, and said:

"Well, I don't know exactly where you came from, or what the mess in your memories is, you can rest assured that this ship is absolutely safe, and the safest in the universe - rather, there is nothing in the universe that threatens the survival of humanity. Because, in the whole universe, the only remaining living life is already in this Sweet Dream spaceship, and our spaceship is the only civilization crystallization in the whole universe that can prove the existence of civilization. ”

I looked at Xiaomeng with horror in my heart and exclaimed:

"What do you mean by that? What does it mean that there are only people left in this spaceship in the whole universe? ”

"Heat death." Xiaomeng looked at me helplessly, his eyes teary, "The universe has passed away. As early as 10 to the 36th power, all galaxies and stars in the universe have stopped producing, all stars have run out of energy, the nuclear fuel in the stars has long been depleted, the stars in the whole universe have died, and for a long time after that, the protons in the universe have also begun to decay, and there is no proton decay in the universe. There is nothing else in this universe except the evaporating black hole and the thermal radiation that is everywhere. The entire universe is dead, and the only remaining part of the energy available in the universe is the nuclear energy left on the Sweet Dream. ”

Xiao Meng showed a confused and sad expression, and said:

"Until the arrival of heat death, human beings have not been able to invent a perpetual motion machine, let alone find eternal energy. With the increase of cosmic entropy and the depletion of available energy, the remaining 500,000 humans on the Sweet Dream will not live for 50 years, and all humanity can do is wait for death on this lonely spaceship shuttling through the boundless darkness. Moreover, if you don't enter the virtual world, human beings won't even live for fifty years, because human beings will have a mental breakdown on a closed and narrow spaceship for a long time, and even have a life-and-death fight because of the competition for food and resourcesIt's like heaven ......"

As Xiaomeng spoke, I walked to the nearest nutrient tank, and in the light blue liquid, there was a very strange-looking creature floating, this creature had a head about the size of a human, the head was hairless, but the body was gray, its body was curled up like a baby, its limbs were completely degraded and curled up, like a fish, it had no neck, no toes and fingers, only thin and short tentacles similar to octopus tentacles. I saw the human-like creature floating in the liquid, and opened its thin eyes, revealing its pure black pupils, and looked at me in panic, it tried to swim its limbs, but it was clear that its short limbs could not allow it to swim in the liquid.

"These things...... What is it?! I took three steps back in horror.

"These are human beings." Xiaomeng walked in front of me, looked sadly at the fish-like creature in the jar with me, and then stretched out his virtual hand, gently touched the surface of the glass jar, and said desolately, "Because I don't know how many generations of human beings on the spaceship have relied on inputting nutrient solutions to maintain life activities, they don't need to labor, and they don't need to move for reproduction, so after reproduction from generation to generation, human limbs and organs have completely degenerated, and only the brain still has the form of primitive humans." It became its current form. ”

"Humanity has degraded to the point where only brains remain, which is sad, but at least it saves a lot of resources for the ship." Xiaomeng smiled sadly.

Then, Xiaomeng turned to Zhu Qingyun and said with some dissatisfaction:

"But you have woken up the last of mankind's dreams, you madman. You caused the Odin system to crash, although only temporarily. However, you are still too terrible. I didn't expect that after I obviously deleted everyone's memories in reality, there were still people who could be in the virtual world and find that the world they were in was fake, and moreover, they also used the logic gates of the two systems to exercise contradictory instructions to create an infinite iterative loop, causing a crash, thus breaking through the Odin system crash and restart. It's horrible, horrible! The computing power and layout ability that you have broken through the 'brain in a vat' technology has never been possessed by anyone since the invention of virtual technology to today's cosmic heat death! ”

My second monk glanced at Xiaomeng in confusion, then at Zhu Qingyun, and said:

"I still don't understand at all, Zhu Qingyun, what did you do as a wooden bodhisattva? And how did you break through the brain in a tank? Hey, wood, can you explain? ”

Zhu Qingyun looked at me with calm eyes like water, and said:

"Due to the ambiguity and imprecision of human language, it is difficult for me to fully describe the whole process of my breakthrough through the Odin system with a complete logical symbolic language structure." As he spoke, Zhu Qingyun turned to Xiaomeng on the side and asked:

"Can you project the specific image I need?"

Xiaomeng retreated, glanced at Zhu Qingyun, and sighed:

"Don't you want to go back to Sodom? Every second you do here consumes more resources. ”

Zhu Qingyun said indifferently:

"There's no need."

"Okay then, if you insist." Xiaomeng lowered his eyelashes, and then, a projection was projected in front of Zhu Qingyun, forming an operation interface similar to that of a laptop, Zhu Qingyun's hands operated in that light curtain, and soon, two drawings appeared in front of me, and on the drawings, were written the two poems that Zhu Qingyun wrote to me.

Zhu Qingyun let the two poems float in front of me, and then said in his tone without the slightest emotion:

"There is no such thing as complete artificial true randomness in this world, and although the world simulated by the Odin system is very close to true randomness, it is still not comparable to the real world in some details. These details are the optical quantum residual effect of the human visual system and the true randomness of human activities. The light source of the real object in the outside world is projected on the human retina, and due to the residual light quantum, there will be a light quantum residual effect of snowflakes even if the eyes are closed, but there is no such phenomenon in the world of the Odin system, so this is a big mistake of the Odin system. Because the Odin system directly stimulates the optic nerve to create nerve impulses to create a fantasy world, it is unable to produce the optical quantum residual effect. Secondly, although the city of Sodom has a large population, most of the people are not really people with free will, but virtual characters created by the Odin system in order to create the illusion that Sodom is a bustling city, and their actions are pseudo-random, and about 93.5% of the people in the city behave in a circular motion. In human terms, it's the set. ”

"I see! Is it any wonder that you said something inexplicable when you first stood on the cliff of Sodom City, and it turns out that you already doubted the authenticity of that world when you were in Sodom City? "I'm amazed." However, it's not just you, in fact, I've long felt that the world is unreal. ”

Zhu Qingyun said calmly:

"It's not enough to just feel like the world isn't real. Only when you perceive that the world is unreal and intend to upset the balance of the virtual world with your actions, will the Odin system send out an amnestic program to forcibly scan your brain and completely erase your criminal memories. ”

"Then the amnestic program, isn't it those black-clothed city managers?" I speculated.

"That's right, the Man in Black is the result of the concretization of the built-in program set up by the Odin system to automatically handle the criminality to reach the risk threshold. If the men in black are not sent to forcibly delete the motives of the perpetrators in the name of crimes, but invisibly and directly delete the memories of the perpetrators, a large number of people with plain and unexplained amnesia will appear in the city. As a result, residents are suspicious and distrustful of the possibility of malfunction in the Odin system's amnestic program, and for this reason, personified memory processing programs such as the Man in Black are necessary to reduce human distrust of the Odin system. ”

Looking at my shocked expression, Zhu Qingyun continued:

"A super system like the Odin system, which can simulate extremely detailed scenarios, is inevitably extremely prone to system vulnerabilities. If you do not perform regular shutdown self-checks, it will lead to the accumulation of bug packets, and even fall into self-referential contradictions such as the barber's paradox, resulting in system crashes. Therefore, the Odin system must need at least two systems to operate alternately in order to ensure that the other system can maintain the virtual world without interruption when one system is down for self-testing. ”

I stared at Zhu Qingyun as uncomfortably as if I had eaten a bitter melon, and asked:

"Don't show off your three-inch iron anymore...... What is self-referentiality? And the barber's paradox, isn't it a mathematical ......?"

Xiaomeng, who was standing on the side, looked at me and explained softly:

Yes, this is the famous Russell paradox in mathematics. The existence of the barber's paradox is also the reason why many systems crash. For example, if there is only one barber in this world, and he only gives haircuts to people who can't do it himself, then should he give himself a haircut? If he gives himself a haircut, he violates his words of only giving haircuts to people who can't get a haircut himself, and if he doesn't give himself a haircut, then he should give himself a haircut...... In this way, whether a barber should give himself a haircut or not will become a logical endless cycle proposition. If the computer also has such an endless loop, it will lead to an infinite number of calculations on this proposition, causing the hard disk to crash due to computational overload reaching the physical limit. That's pretty scary. When the object of a sentence involves oneself, there is often a contradiction, which is a self-referential contradiction. It's like a child jokingly saying, 'I'm stronger than anyone else in the universe,' and when I say I'm better than anyone else, is 'I' a human being? If 'I' is a human being, then 'I' is stronger than 'I' myself, and then, in order not to let 'me' surpass 'me', I have to be stronger, so it will create a logical cycle of infinite ascent. ”

"In order to avoid the barber paradox of the Odin system, which leads to an endless loop and cannot continue to work, it is necessary to ensure that the two systems work alternately. In this way, if there is a conflict between the barber, a new 'barber' can be brought in from another system B as a rescuer to cut the hairof the barber in system A who cannot give him a haircut, so as to solve the conflict. ”

"The kind of contradiction you are talking about...... Will it appear in the virtual world? I wondered.

"Yes. For example, a city management of Sodom that must eliminate criminals who disrupt the city's law and order in order to maintain the city's law and order is a contradiction. Xiao Meng said, "If that chengguan himself committed a crime and destroyed the city's security, then should he eliminate himself?" If he destroys himself, he will not be able to continue to maintain law and order in the city, and if he does not eliminate himself, then he will be a criminal, in this case, a paradox arises. Therefore, only the intervention and judgment of other systems can eliminate bugs. In this case, the virtual world in Odin's system has not appeared before. Even human institutions throughout history have been constrained by this paradox. For example, a political party that is responsible for maintaining national stability and eliminating all factors that undermine social stability should eliminate itself when it is a factor that undermines social stability. ”

Little Dream's words came to an end, but I couldn't help but fall into deep thought.

Zhu Qingyun continued:

"In order to solve the contradiction of self-referentiality, the Odin system must have at least two systems operating alternately, and at a certain point in time, the simulation information of system A will be reproduced to system B, as long as I find the interface of the two systems for information flow, I can create infinite iterative operations, so that the two systems fall into each other's command contradictions and attack each other."

"Two systems...... Attacking each other? "My brow furrowed." Why do two systems attack each other? ”

"Because in order for the two systems to be able to execute their own instructions, they can only eliminate the instructions that the other party prevents the execution of their own instructions." Zhu Qingyun said, "The Odin system will automatically repair the body information of the dead in the city of Sodom, which I have proved using the massacre experiments conducted by Father Luther. ”

"You used Father Luther for the slaughter? Could it be that Father Lutheran has a mental problem, is it your fault? I was stunned.

Zhu Qingyun truthfully admitted:

"That's right, I gave Father Luther a large amount of hyperstinol, causing him to be extremely agitated and confused, thus causing the massacre. From the sight of a passerby recovering immediately after being shot by Father Luther, I came to the conclusion that the Odin system repairs all the structures of the human body within three seconds of death. At the same time, the Odin system also automatically destroys the memory of risk that could cause damage to the Odin system. ”

"So, I took advantage of these two features of the Odin system, and at the moment when the two systems were about to interact with the flow of information at the beginning of the interface at midnight, I split my left and right brains, causing the two systems to produce completely different instructions:

"System A had to immediately delete the memories in my brain because the man in black detected that my brain had dangerous memories when he touched my body."

"System B detected structural damage to my brain and had to fix my brain immediately."

"Since my brain was cut in half, both systems swept across my left and right brains at the same time, so System B, which swept through my left brain, began to repair my brain, and the memories in the brain are closely connected to the brain structure, and repairing my brain structure means restoring my memory. The other system, System A, swept through my right brain, detected dangerous information, and began to delete and destroy my memories, so the instructions of the two systems became diametrically opposed. System A thinks I'm dangerous and needs to erase my memory, so System B, which is repairing my brain, becomes its nemesis, so it must destroy System B's program to prevent it from continuing its mission. System B, which repairs my brain, thinks that System A is the source of destruction that prevents my body from recovering and wants to destroy my body, so in order to restore my body, it must prevent System A's instructions from executing...... As a result, the two systems began to hate each other, destroying each other's program code, falling into an endless and infinite iterative destruction, which eventually led to the collapse of the two systems together, and all players in Odin's system were forcibly logged out. ”

"I see, no wonder you always delete your memories over and over again...... So it was to prevent the Odin system from scanning your brain for high-risk information? It dawned on me.

Zhu Qingyun nodded slightly:

"Yes. The Odin dual system interacts with each other to store information 24 hours a day, and scans the human brain every hour. Therefore, I must actively delete my own memories before the Odin system scans my brain to avoid being discovered by the Odin system The risk component of my memory, because unlike the deletion of memories by the Odin system, the active deletion of memories can be permanently deleted, while the deletion of your memories by the Odin system is only a temporary copy of your memory. And if I let the Odin system back up a copy before deleting my own memories and then delete them in a targeted manner, there will be a possibility that the Odin system will discover the dangerous information in my memory, so I have to manually delete irrelevant memories except for the dangerous memories that destroy the Odin system. Because it was manually deleted without going through the backup memory of the Odin system to be targeted and accurately deleted, it led to a large loss of my memory and was completely restored, and I don't even know Murong Yin. ”
