"Is there nothing to ask?" Lu Yuan asked.

Su Mei shook her head: "You can continue talking."

Lu Yuan nodded and began to continue talking: "I just talked about the technological explosion."

"Civilization needs to survive, the universe is limited, the existence of suspicion chains cannot judge the good and evil of civilization, and the technological explosion makes even weaker civilizations become very terrifying in a very short time scale."

"These four points are the four key points of the Dark Forest."

"These are all conjectures, humans cannot imagine, they can only associate. These are all associated with human common sense. If there is really a terrible civilization that makes you mistaken when you think about it, then any speculations about them by humans will seem ridiculous."

"It's like when a human is thinking, God laughs."

"But even so - we can't stop thinking."

"As for the next step, they are all assumptions, and they are also assumptions based on the level of human thinking."

"We may say something wrong and think something wrong, but we cannot stop talking because of mistakes, and not think because of mistakes."

"First, the civilization in the universe only has the lowest degree of goodwill."

"This starts from human beings themselves. For strangers, we generally do not have aroused sympathy, or in other words, we are the most important thing. We will not rush up to take out all our money to help him when we see someone on the roadside. In fact, we just don't pull out the knife and stab him immediately."

"This is the so-called minimum degree of goodwill."

"If you don't mess with me, then I won't mess with you."

"And the second assumption is deadly."

"That is, communication will definitely expose the position of civilization."

"The speed of light is limited, so I think that the basic communication methods of civilization are carried out at the speed of light, because we have not yet observed a faster communication method than the speed of light. This is our limitation. Even if the communication in the quantum entangled state is currently used for encryption, not for ultra-long-distance communication."

"Using various electromagnetic waves at the speed of light to communicate is not simply informing, but communicating back and forth, which means being exposed to the other party's eyes."

"In addition to the existence of the suspicion chain, any communication will become meaningless."

"The third: the degree of cruel competition among civilizations is comparable to that of the dark battle."

"Or it is more cruel than the Dark Battle. After all, we have said before that the Dark Battle takes place among humans. A few days ago, they were still comrades who could go out to drink and chat together. However, when each other's warships were separated, when the fuel and supplies were insufficient, when only the other warships could be swallowed up could survive, and when the other's true intentions could not be verified, the Dark Battle quietly spread its black wings."

"Then, the degree of competition among civilizations with different foundations is far beyond imagination, after all, there is no equality between them."

"You will be sad about the tragic death of a kitten and puppy, because we are mammals of each other, and they look so cute."

"However, when you put a crab alive on a ladder cage and let it be killed the most cruelly when you are alive, you will only sigh at the deliciousness of the crab, because you may substitute yourself as a kitten and a puppy, but you rarely substitute yourself as a crab."

"The gap between the two civilizations is actually far beyond the gap between humans and crabs."

Lu Yuan looked at Su Mei and said, "Maybe we are completely different from their understanding of this world."

"This is the fourth point."

"That is, it is difficult to communicate between different intelligent species."

"After all, it's so difficult for us to communicate with crabs. The only thing in common is to judge whether the crab is delicious or not."

“This will bring greater dilemma to the communication.”

"The next is the fifth hypothesis."

"We assume that all civilizations have a long lifespan."

"It is not that smart creatures have a long lifespan, but that civilizations have a long lifespan. What is civilization?"

Lu Yuan looked at the ceiling: "We are civilization."

"As long as our history, tradition, memory and culture can be passed on, it is the existence of civilization itself. Therefore, the king believes that even if a robot replaces the position of human beings on the earth, as the successor of human beings, robots can still represent human civilization."

"It is very difficult for any life to evolve to the level of civilization. However, once any life evolves to the level of civilization, if it does not destroy itself, it will be difficult to be erased by simple external forces. Just like the humans on Earth are far from being powerful, but thousands of years ago, we became the most powerful and successful species on Earth. Now we are gradually transforming nature to dominate nature and embarking on the land of the journey to outer space."

"So, as long as it is not eliminated by irresistible external forces, we can see that every civilization has a long life span on a time scale."

"So, if you find another civilization in the universe, your two choices."

"First, let you know my existence."

"Second, let you exist."

"It's very dangerous for me."

"This goes against the axiom that survival is the first need of civilization."

"Then, if I have a cheap enough weapon on hand to destroy your civilization without being discovered and retaliated, then I will use it without hesitation."

"Before you're growing enough to threaten me."

"No need to consider whether you are a good or malicious civilization, because this kind of thing is often the same as Schrödinger's cat."

"Not only do I don't know the life and death of a cat before I open the lid, but more importantly, due to the need for civilized survival, I tend to be kind-hearted when I am weaker than you, but if I am stronger, then I undoubtedly tend to be malicious."

"So, another key point of the Dark Forest strike is not to expose who you are."

Lu Yuan said this very casually, and Su Mei had no chance to interrupt, nor did she interrupt.

Because just listening is enough.

"These are just things in that book? A science fiction?" Su Mei asked.

"After all, human thinking itself is a precious existence." Lu Yuan said: "This book brings up some interesting thoughts. I can't be sure what he said is right, just like I can't be sure if the sun is extinguished or not is a dark forest blow."

"But-at least, we can work hard, and the last time we went out, we knew nothing."

"But at least this time, we can know - how the sun is extinguished."

"What does this require?" Su Mei asked.
