"Dark Forest? What's that? Liu Guangliang looked at Zhang Tiancheng in surprise.

"The universe is a dark forest, and every civilization is a hunter with a gun, sneaking through the forest like a ghost, gently brushing away the branches that stand in the way, trying not to make a sound from his footsteps, and even breathing carefully...... He had to be careful, because the forest was full of hunters who were just as stealthy as he was. If he found another life, whether it was a hunter or not, whether it was an angel or a devil, whether it was a delicate baby or a faltering old man, whether it was a fairy girl or a godlike boy, there was only one thing he could do: shoot and destroy it. In this forest, others are hell, eternal threats, and any life that reveals its existence will soon be wiped out. This is the picture of cosmic civilization, and this is the explanation of Fermi's paradox. Zhang Tiancheng's voice was depressing, but it was clear.

"? It sounds so profound, what the hell is in your head? I'd love to break your head open and take a good look. Liu Guangliang was shocked by Zhang Tiancheng's words, and he forgot to drink the wine.

"Don't, don't bury me, I didn't say it this time." Zhang Tiancheng touched his nose in embarrassment, "Da Liu's "Three-Body Problem", one of the settings in it, the law of the dark forest. ”

"Oh, you say yes, anyway, my old Liu doesn't like to read, and I don't know these esoteric things." Liu Guangliang looks like he loves something.

Zhang Tiancheng was amused by Liu Guangliang's appearance and laughed all of a sudden, "It's not that I said yes, but what I said in that book, a very interesting setting, which can't be confirmed, but it can't be refuted." Zhang Tiancheng paused, took a sip of wine, and then said: "There is also a cosmic sociology created in it, and there are two basic principles in it, do you know what they are?" Uncle Liu? ”

"Don't sell me guanzi, what can I know?" Liu Guangliang patted the back of Zhang Tiancheng's head.

"Oops, what are you doing with me? The two basic principles of cosmic sociology: first, survival is the first need of civilization; Second, civilization grows and expands, but the total amount of matter in the universe remains the same. Zhang Tiancheng slowly rubbed the back of his head and said unhurriedly.

"Huh? Also cosmic sociology? The earth has not been understood, and human beings themselves have not understood it, and they have begun to think about the universe? Damn, I don't agree much with the first point. "At this moment, the sky has completely darkened, there is no electricity, there is no usual haze, and the night sky is starry at this moment, which is extremely beautiful.

"How do you refute it?" Zhang Tiancheng looked up at the starry sky, his eyes reflected in the starlight, and he looked fascinated.

"It's very simple, you think, if survival is the first need, the first thing you need to understand is survival, what is the most basic thing to ensure survival? Life. Only by living can you have the capital to survive, right? Does that mean that life is the first need? Let's not talk about the universe, the universe is huge, let's talk about the earth, let's talk about human beings. Human beings have to be regarded as a civilization, isn't it wrong to say that the first need of human civilization is survival, but can it be said that the first need is life? Hey, it seems to be okay, then it's a little smaller, put it to the individual, hey, this theorem is unreliable. Why do you say that, how many people shed their blood for their faith and for the country? Are they putting their lives on the line? Whether it's life or survival, is it no longer the first need? Throughout the history of the development of human civilization, imagine human beings as a big society, and there have been various civilizations in history, both extinct and continued, but do they regard survival as the first need? I may have done it, but it disappeared anyway! Do you know why? Liu Guangliang paused, took a long sip of wine, and continued, "Because there are many people who think that there is something more important than their own lives." Some people can sell everything for money, including their own lives, drunkards can throw away their lives for a sip of wine, and lustful people would rather die on the belly of beautiful women, sell their souls, and sell their lives to get the temporary, so-called peace that they think they think, hehe, fools. ”

"You're too deckery, you're changing concepts!" Zhang Tiancheng sneered.

"Hey, don't you care if I change my concept or not, you just say it's right?" Liu Guangliang began to play shamelessly.

"Ah, yes, yes, who is my Uncle Liu, the reincarnation of the gods......" Liu Guangliang forced him to go down the stairs, can Zhang Tiancheng not give it? I have to give it, and I have to give it to my satisfaction.

"Hahaha, of course, count your kid acquaintance. Man is inherently dead, or heavier than Mount Tai or lighter than a feather. Liu Guangliang raised an eyebrow.

"Okay, I will do you too, life is precious, love is more valuable, if it is for freedom, both can be thrown. Doesn't that mean that there is something more important than life? Do you think it applies in the universe to civilizations that may have zero morality? Zhang Tiancheng also raised his eyebrows. His gaze never left the starry sky.

"Oh, you're just idle, what do you want to do so much? Adding to your worries? Liu Guangliang drank the last sip dry, slapped the wine gap, and patted Zhang Tiancheng's shoulder very "friendly", Zhang Tiancheng's shoulder blade was almost broken by Liu Guangliang. For a while, only Zhang Tiancheng's voice mixed with screams greeting each other's parents remained.

In fact, Liu Guangliang didn't finish speaking, he still didn't say one thing, that is, the law of the dark forest only applies to two civilizations or civilizations, and there is no communication or contact between them. If there is some contact between the two, the law of the dark forest may have to be changed.

……

The next day, early in the morning, there were five people in the village, and dozens of people in the village. The people of the village looked at the people below the village from afar. There is no way, who let the village be built on the mountainside, who made them cowardly as mice.

"You think about it, I'll give you one last chance, we're going to Stone City, it's not a joke!" Liu Guangliang looked at Li Qiang in front of him with a serious expression.

"You said that you have such a distinctive face, but your name is so popular, I have been in school for more than ten years, and there are no less than five classmates named Li Qiang, not to mention people who are not classmates, and today I met another one, it is really a creation and a man!" Zhang Tiancheng "added" next to him.

Li Qiang ignored Zhang Tiancheng's mockery, his face was cloudy and uncertain at the moment, and he knew that he was making a choice. For Li Qiang, time may have passed for a long time, but for Zhang Tiancheng and Liu Guangliang, it was only half a minute.

"I'll follow you!" An answer that surprised both Zhang Tiancheng and Liu Guangliang.

"Okay, it's good, it's good, I can't see that I'm still a man who is not afraid of death! My Lao Liu misjudged you! Liu Guangliang patted Li Qiang's shoulder heavily, Li Qiang, like Zhang Tiancheng, gasped in pain. It's a pity that he can only greet Liu Guangliang's whole family in his heart, if he dares to say it, he can't guarantee that the Tang knife will have a close contact with his neck.

"Okay, what about the two of you?" Liu Guangliang looked at Han Xiaochuan and Wang Jie behind Li Qiang again.

The two of them hurriedly shook their heads, indicating that there was no objection. Zhang Tiancheng, who was standing on the side, was not interested in paying attention to these things, he lit a cigarette for himself, then opened the car door and sat on the co-pilot, spread out an atlas, and looked at it seriously. The atlas was found in the previous two-story building. National highway and rail network. It has a role to play in these last days that cannot be ignored.

Several people who were originally enemies came together by mistake because of a few words. Alas, the old saying is true, there are no permanent enemies, only eternal interests. Liu Guangliang's strength is obvious to all, and his identity is mysterious and his origin is unknown. I can't say that my brain is good, but I am definitely not stupid, although the three of Scarface are not very good, but after so many years of mixed society, I have long exercised a good ability to observe words and colors, plus the skills of these three people are still good, and they can fight and kill for so many years, which also shows that they are not very life-sparing people, and they all pay attention to the word "righteousness" on the road, and they should be able to help themselves a lot if they are well educated. As for those villagers on the hills? Zombies are not something that is fixed and immobile, and being safe for the time being does not mean that this situation can continue forever. If you don't dare to resist, and still hold the self-deception of the old era, the final result will either be destroyed in your own hands, or enter the mouth of the zombies. This is what Zhang Tiancheng thinks about in the moving car.

A small group is beginning to take shape.
