Just as Qi Zhengdao was taking a plane and lamenting at a high altitude.

Menld only started watching the 35th episode of "The Past of the Earth" at home.

According to the trailer, this is the penultimate episode of the second part.

Following the previous episode, this episode will definitely be very exciting. At least, Mende thinks that he should explain the significance of cosmic sociology.

Mengerde took a shower and changed his clothes, turned off all the chat software before he started watching this episode.

At the beginning of the plot, Luo Ji and Shi Qiang were both.

Luo Ji asked everyone to go home to maintain urban order, and then came to a desert with Shi Qiang.

"Let's start."

Luo Ji spoke, he wanted to explain to Shi Qiang why that star was destroyed.

He told Shi Qiang two axioms of cosmic sociology.

[First, survival is the first need of civilization.]

[Second, civilization continues to grow and expand, but the total amount of matter in the universe remains unchanged.]

Although Shi Qiang could understand these two obvious words, he could not infer anything from them.

"First of all, let's talk about the dark battle. If I say that the Starship Earth is a microcosm of cosmic civilization, do you believe it?"

"No, Starship Earth lacks resources like fuel and accessories, but the universe is not short of it, the universe is too big."

"You are wrong. The universe is big, but life is even bigger! This is what the second axiom shows that the total amount of matter in the universe is basically constant, but life grows exponentially!"

With the conversation between the two, the picture also drifted from their backs to the starry sky, with stars dotted, and transitioning to the sea.

The bacteria in the sea are constantly splitting and growing exponentially. Without being restricted, they quickly fill the entire ocean of the earth.

Civilization, born from a planet, has grown so rapidly, lighting up countless galaxies.

Seeing all this, Mende began to think at the same time.

Soon, he thought of the theory of evolution.

The first stage of evolution theory is free reproduction, and organisms reproduce unrestrainedly in the environment, gradually reaching the limit of environmental accommodation.

So the next step should be survival competition?

Menld suddenly shivered.

Survival competition in the earth's environment expands it to the universe.

Isn’t that a war of civilization?

A word emerged in Mende's mind. He couldn't remember which comment or analysis he saw in "The Past of the Earth". Originally, he just thought the composition of this word was very interesting, but now, he thought it was very appropriate to describe the current situation.

Survival and death situation.

"No need to look at it in the long run, the entire universe is now in a situation of survival and death."

Luo Ji said.

The universe has a history of more than one billion years.

Even though life has only developed for billions of years, it is enough to spread throughout the universe.

Even if the emergence of life itself is a low-probability event, it is inevitable to multiply to the vastness of the universe.

Judging from the current signs, the universe is likely to be filled with life.

"This is not right. The universe looks empty. Apart from the three-body man, I don't see any other alien life?"

Shi Qiang asked back.

Luo Ji lit a cigarette for each of them and stood a little further.

In the dark night, there were only Mars on the cigarette butts, emitting a glimmer of light.

Luo Ji then defined the good and evil of civilizations. A kind civilization is the world that does not actively attack and eliminate other civilizations, while an evil civilization is the opposite.

"Next, you already know the existence of my civilization in the universe. Think about it and what choices are there for me."

Luo Ji asked.

"I chose to communicate with you?"

"If you do this, you have to pay your own price and you have exposed your existence."

The two people said and said, gradually outlining a picture of communication and exchange between two civilizations under the scale of the universe.

Since the other party’s civilization cannot be confirmed, and at the same time, the other party cannot confirm our good and evil, the communication is not established.

This is the chain of suspicion, which has nothing to do with the good and evil of civilization. It is the result that will inevitably be achieved in the context of the universe's first need for survival.

At the same time, technological explosion is the ability that every civilization contains, especially after learning about other civilizations, this explosion will be faster, so this also cuts off the idea of ​​communicating with other weak civilizations when discovering other weak civilizations.

"Then I can only keep silent."

Shi Qiang said, and suddenly felt something was wrong.

"That's not OK. If you are stronger than me, since I can discover you, you can definitely discover me. If you are weaker than me, but there is a possibility of a technological explosion, it becomes the first situation. To sum up, whether it is to let you know my existence or to let you exist, it is dangerous for me."

"Dashi, you are such a clear-headed person."

"From here, my head can still keep up with you."

Hearing Shi Qiang's words, Luo Ji was silent for a while before saying.

"The great history is not the beginning, our inference is over."

When Menger was heard this, he was stunned.

He was still waiting for Luo Ji to continue to use the civilization picture of cosmic sociology, why did it suddenly end?

Mende tried to understand, but saw Shi Qiang on the screen understand something and cursed.

"Extrapolate your choice to billions of civilizations among hundreds of billions of stars, and the big picture will come out."

Luo Ji nodded.

"This is too dark."

"The real universe is so dark."

Luo Ji extinguished the cigarette butts and the world fell into darkness.

"The universe is a dark forest. Every civilization is a hunter with a gun, sneaking in the forest like a ghost, gently pushing away the branches blocking the road, trying hard not to make any sounds in the footsteps, and even breathing with caution."

"He must be careful, because there are hunters who sneak like him everywhere in the woods. If he discovers another life, no matter what the other party is doing, there is only one thing he can do: shoot and destroy it!"

"In this forest, others are hell, an eternal threat, and any life that exposes one's existence will be quickly destroyed."

"This is the picture of cosmic civilization, this is the explanation of Fermi's paradox."

The picture is farther away from the earth, and billions of stars shine. This is a brilliant ocean of stars, but at this moment, in Luo Ji's mouth, these stars radiating light are the darkest forest.

Shi Qiang lit another cigarette, which made the world a little shine.

"But in the dark forest, there was a stupid child named Human, who set a fire and shouted beside him: I'm here! I'm here!"

Luo Ji said, unable to hear what the meaning of the tone was.

Menld heard all this.

The inner shock is unparalleled.

At this moment, it is rare to be sunny in Jingping.

Although there are no stars at night, the moon still shines on the earth.

Menld looked out the window.

Suddenly I felt a sensation of fear.

Who knows that in this starry sky, how many hunters saw the shouts of the earth, and how many hunters were waiting to shoot?
