Notification on the Handling of the Incident of Yingzheng Raising Zombies

Chen Chrome was taken aback by the question, took out the parchment roll given by Yan Chuan from his arms, and unfolded it.I drew a total of six "positive" characters on it, and the last one was just a stroke away, so I replied: "Today is No. 20 nine days."

Holding the wine glass, Li Xinglan shook it in a circle, and a dark yellow petal floated up and down in the wine, with a calm tone: "In 2035, South African Rainbow Mining will carry out deep excavation operations at a depth of 500 meters under the Rand Shield. A piece of black stone with unknown regular shape and composition was mined. The technicians found no abnormality after the inspection, and was picked up by a miner for collection. A few days later, an epidemic broke out in the mine, all the miners were killed, and the mine was permanently shut down. Closed. Later, an acute infectious disease of the central nervous system of unknown cause broke out in South Africa."

Chen Chrome: "It's written in the history textbook."

Li Xinglan: "Yes, the virus appeared in the world in 2035. It broke out and spread rapidly, causing the population of Africa to drop to one-tenth. A feasibility report on the use of zombies as a new energy source. However, this technology was not 'declared mature' until 2036."

Chen Chrome: "Due to various natural disasters*, the fertility rate of the population has dropped sharply, and there are less than 20 billion people left in the world. Zombies began to be used as a kind of cheap labor, a new type of clean energy, and were exported in large quantities in the face of the world. Ten years later In [-], a series of economic, social, and moral issues emerged one after another. I remember that my elder brother read "Zombie Ethics" as a compulsory course in college."

Li Xinglan nodded: "How long did it take us to eliminate the threat of zombies, study the causes of zombies, and finally develop a new technology?"

Chen Chrome: "It's over! Why didn't I think about it carefully? It took the top scientists four years, how could the ancients do it in just four days."

Li Xinglan stared at the words on the parchment, frowned slightly, and said, "Even if it is a 'Gu worm', it is just a technology that few people know about. How long does it take for a technology to be developed and put into use? Even if it is to control the Gu worm The technique of using Gu worms to successfully control zombies has existed since ancient times, but is it possible to complete the technique of using Gu insects to successfully control zombies in these few days? Your inferences are likely to be all wrong. What Qin people mastered is not the black stone brought by Brother Jiang, but It is the Black Stone that originally existed in this world, or other virus carriers."

Chen Ru was actually a little lucky, and asked: "This means that the black stone is likely to become two pieces, and the eldest brother is still safe? However, it is impossible for the same thing at different time points to exist at the same time. Could it be that the black stone of our era That black stone, disappeared?"

Li Xinglan shook his head: "We are three-dimensional creatures, living in four-dimensional space, and the arrow of time is absolutely one-way for us. Do you really think that the present world is just a point in time in the past, and we're back"? "

Chen Chrome's scalp was numb: "..."

Li Xinglan: "At that time, you fainted and didn't hear the message from Brother Jiang."

The elder brother's words immediately surfaced in Chen Chrome's ears, so real, yet so far away.He was a little sad, lowered his head, and said: "No, I remember very clearly, he said, 'Look brother, we are now above China, we all love you, we must live, dear.' This sentence has what is the problem?"

Li Xinglan sighed, shook his head, and said: "There is a sentence wrong, it's not 'must live on, my dear', but 'you must live on, love your dear.'"

Chen Rue felt a chill creeping up from the soles of his feet: "Don't make trouble, I'm a little bit... panicked, turn back time?"

Li Xinglan: "Do you know the equation of Einstein's gravitational field? Gödel, Stockum and many scholars have worked out some solutions to prove the possibility of time travel."

"Sorry, excuse me." Chen Chrome raised his hand, as if he was asking a question in class, and after receiving a nod from Li Xinglan, he said, "I just graduated from junior high school, so I may not understand things that are too complicated."

Li Xinglan frowned slightly, but Chen Ge was nervous, so he still noticed this subtle movement, and immediately felt that he was too embarrassed.

"It's okay, Chen He, my understanding of these theories is also very limited, it's just a possibility." Li Xinglan paused, trying to slow down his tone, like a persuasive teacher, and said: "You know what? ?Until our time, the scientific community generally believed that it was impossible to go back in time: first, the universe has been expanding at an accelerated rate; second, the second law of thermodynamics, the total entropy of an isolated system will not decrease."

Chen Chrome: "My mother taught me that entropy is the degree of 'disorder' in a system, but it is too abstract, and I can't figure it out at all. Moreover, what does the expansion of the universe and the increase of entropy have to do with time?"

Li Xinglan suddenly stretched out his right hand, and his slender fingers touched Chen Chrome's skirt: "It's not appropriate to use metaphors to explain these problems, but they are very vivid."

Chen Chrome's breathing was stagnant for no reason, and even his heart missed half a beat.

Li Xinglan's fingers slid down, and took out the dogwood that Chen Chrome stuck in his neckline.

As soon as he left his hand, Chen Chrome's heartbeat increased suddenly, and his face flushed.

Li Xinglan drew a square on the mud floor with stones, picked nine red dogwood fruits, and kept them on the ground, saying: "The arrangement of these fruits is disorderly, and they are rolling all the time. If I ask you if one of them is in the Where, different times will get different answers. They are very unevenly distributed, and there are countless kinds of this uneven distribution."

Chen chrome nodded cautiously, like the tail of a crane that was being taught by the teacher.

Li Xinglan arranged the cornel fruits neatly, three in a row, three columns in each direction, and said: "Now they are arranged in order, and you can accurately describe the position of any fruit, for example, this one, the second column The second row. In this square, only this arrangement is the most uniform."

Chen Chrome nodded, and actually understood something: "The distribution is uneven, subjectively it makes people feel very chaotic, so the degree of chaos we talk about is all the possibilities in the first case, which is entropy? It is a numerical value."

"Smart, although not accurate, but very close." Although Li Xinglan denied his answer, he used an encouraging tone and continued: "The total number of all possible states is called the number of micro states. In statistics In thermodynamics, entropy is a function of increasing number of microstates."

Chen Chrome: "I finally understood a sentence! A function is not a number. Then why does the entropy increase?"

Li Xinglan messed up the fruits, picked up one, put it in another place, and then took it back: "In this closed system of a square, there are two random processes, which you can simply understand as two ways of movement." .One is reversible, I take it out and put it back in its original position, and there is no change at all from the beginning.”

He peeled one of the fruits in half and said, "The other one is irreversible. If I break it apart, you can't make them stick back together."

Chen Chrome: "Understood, the reversible process has no effect on this system. The irreversible process increases the possibility and increases the number of micro-states, so the entropy also increases. But we can't stick the fruit back, so the entropy will only increase, not decrease."

Li Xinglan put the two halves of the fruit back together and put it back in its original position: "Yes, your thinking is very clear. If we let time 'reverse' the original, assuming that the two halves of the fruit go back according to the original trajectory , and then fully fused together, and changed back to the original state. Their bonding needs power, where does the power come from? This is actually still an increase in entropy. Even though time seems to be reversed on the surface, everything is different. The conclusion is: entropy is a reference coordinate for the flow of time, based on the fact that entropy can only increase continuously, the arrow of time has only one direction."

Chen Chrome: "I seem to understand a little bit. Even if everything happens backwards according to the past track, the direction pointed by the arrow of time does not change. What's more, human beings in this system seem to be unable to experience the rotation of the earth. We can neither realize that these things have happened, nor realize that the past has become the future. Therefore, there is no possibility of time going backwards, either subjectively or objectively. But if we assume that entropy can be reduced, it will happen again What?"

Li Xinglan: "There are countless states with lower entropy than the entropy at this moment. No one knows to what extent the entropy will be reduced and become the exact state. Assuming that the entropy can be reduced, it is like For unknown reasons, the two halves of the fruit can spontaneously recombine into one, how can you guarantee that they will heal from the original gap according to your will? Can't they heal from the back? They can't be attached to other fruits ? That ends the discussion of entropy, my explanation is just to help you understand the rest."

Li Xinglan touched his waist naturally, pulled off a small half of a mandala leaf and hid it between his fingers. When he picked up the wine glass, he secretly put it into the wine, and then drank it all in one gulp.

Chen Chrome smiled wryly: "Well, things like going back to the past only exist in the beautiful imagination of human beings. In short, it is impossible for people to go back to the past, so why did we come here?"

The wind was blowing, the fallen trees were rustling, and the autumn mood was strong, and the two were silent.

After a while—

Li Xinglan's voice sounded in Chen Chrome's mind: "Don't continue the discussion."

Chen Chrome was puzzled, looked at Li Xinglan, clearly heard his voice, but didn't see him open his mouth to speak.

Li Xinglan: "Don't talk, something is eavesdropping."

Chen chrome opened his eyes wide, recalling the experience in the pool, trying to imagine what he wanted to say in his mind, thinking: "What is it?"

Li Xinglan: "I can't tell, it's just a feeling, for a very short moment. Don't tell anyone what we talked about, everyone on the spaceship can't believe it."

Chen Chrome: "Professor Ruan is credible."

Li Xinglan: "Don't mention it even if it's credible, it's not that simple."

Chen Chrome thought: "Alright, do you know everyone else on the spaceship? I'm very worried about Professor Ruan, he's in poor health."

Li Xinglan: "I, g, Ruan Linzhou, you all know each other."

Chen Chrome thought: "What is g?"

Li Xinglan: "Your brother's... that German. There is also a Japanese, an Indian, two Americans, and another German."

Chen Chrome tried hard to recall, but couldn't remember clearly anyway, just thought: "I remember a red-haired man made the first move, and then I passed out. There was a fierce battle on the spaceship, two people died, no, Three people. Then, what happened later? I passed out."

Li Xinglan: "Fabian is a German spy. He killed Leslie and Berg, knocked you out and tried to open the box, and was finally killed by G."

Chen Chrome was surprised: "I always thought he was a cook."

Li Xinglan: "G is a killer, you should stay away from him in the future. Ju Yixin is a doctor and Su Kela is a scholar. I have never dealt with these two people."

Chen Chrome asked, "How do you know so clearly?"

After being speechless for a long while, Li Xinglan finally spoke after more than ten minutes: "I have my reasons, and I will tell you later. You go back first, and I... think about it later."

Chen Chrome was fascinated by the conversation just now, and he didn't know when Bei Chen came: "Okay, you want to be quiet, I want to go back and sleep with Jing Jing."

Beichen squatted aside, ate up all the Chongyang cakes, and there was not even a mouthful of wine left.

Chen Chrome: "..."

Beichen licked his lips.
