"Human beings are intelligent beings with high technology." Zhou Qing did not agree with Liu Fei's opinion.

"What is wisdom? Intelligence is just another form of force, and in fact, it's no different from the dinosaurs' strong limbs and sharp teeth. When the dinosaurs dominated the earth's land, human beings were still humble sea creatures, so the strength was only relative, not absolute. In the eyes of many creatures, human beings are powerful and invincible, but in the eyes of many creatures, human beings are vulnerable. AIDS, the Black Death, the influenza smallpox, etc., have all been cruel to human soil, and mankind can only watch the death of its own kind without any way-"

"However, we are now able to treat the diseases you mentioned." Zhou Qing retorted.

"What about the new germs?"

Zhou Qing was speechless for a moment. Although the level of human science and technology is getting higher and higher, as the scope of human activities becomes larger and larger, there will always be some untreatable diseases that give human beings a headache.

"Actually, this is also a kind of war, a war between humans and creatures, this is a war to the death, there will only be one winner, and the only end for the loser is death."

"The destruction of mankind is not something that disease can destroy." Zhou Qing said resolutely.

"I'm just using an analogy, human beings are under threat all the time, we can easily kill the virus, then, there will be a creature that can easily kill us humans, as easy as we trample on ants, one day in the future, human beings will become extinct like dinosaurs, leaving only some remnants for more advanced creatures than us to hang on - of course, the greater possibility is that we will leave nothing behind, even a skeleton-"

"Don't-don't-don't say it, I'm afraid-" As soon as Zhou Qing spoke, she suddenly had a strange feeling, she used to be a woman who didn't let her eyebrows go, but in front of Liu Fei, she always showed a soft and weak side.

"What should come will come, but it doesn't have to be for the worst. At present, mankind has learned to coexist peacefully with some species, and even reserves some free range for others, which is a kind of civilizational progress, and if this progress can be carried out to every corner of the universe, then the death of the universe will not be completed by higher intelligent life, but by another unknowable cause-"

"I don't understand, do you mean to say that the disappearance of the universe or the extinction of living things is caused by advanced intelligent life?" Zhou Qing looked puzzled. In Zhou Qing's knowledge field, the universe as he knew it collapsed because the universe itself collapsed at the end of its life, leading to the extinction of all living things.

"Theoretically, the destruction of the universe is the process of the universe itself, but advanced intelligent life can change this process, unfortunately, so far, it seems that all advanced intelligent life is accelerating the death of the universe - you look at the stars in the sky, there is a star behind the starlight, but in the process of human cosmic exploration and migration, people have found that those stars have long ceased to exist, I suspect - "

"What?" Zhou Qing was a little nervous and urged.

"I suspect that tens of millions of years ago, or hundreds of millions of years ago, there were intelligent beings who ransacked the seven star fields where we humans now live, and in this kind of looting, all life disappeared, the star fields became barren, the space became dead and silent, and countless planets were completely destroyed-"

"Then why did we humans appear?"

"In fact, the universe is like a huge intelligent life, although it is not aggressive, but it has a certain amount of creativity, for example, through amino acids to create life, in the long river of time, the universe slowly repairs this damaged star field, one by one barren planets become vibrant, one by one new stars appear. It's a pity that this speed is too slow, tens of millions or even hundreds of millions of years to give birth to the life of human beings at the level of life intelligence. Compared to the speed of those marauders, this speed is simply negligible. ”

"I've never understood what a species can do when it's smart enough to easily raid a star field. Is it necessary to plunder and destroy? ”

"Energy." Liu Fei said slowly.

"In this universe, energy is inexhaustible, is it necessary?"

"Who told you that energy is inexhaustible?"

"Ahem-a-ahem-like the sun-"

"Don't you know that solar life has time? They are not eternal. A planet like the sun burns for only 5 billion years, but in fact, when it is 3 billion years old, the gas emitted by the sun is no longer suitable for human life, and those wind, solar energy, and oil and coal formed by photosynthesis will all disappear. ”

"Humanity can find another sun." Zhou Qing retorted.

"What about the sun you are looking for after it dies?"

"Look for it again—"

"Yes, look again, until all the suns are gone. In fact, we don't need to be pessimistic, the sun is also constantly being born, according to the data, the Huanxing not far from the Zall Star is also a gaseous planet composed of hydrogen, but because its mass is less than the critical mass, the internal pressure and temperature cannot meet the conditions for thermonuclear fusion, so it can only be a gaseous planet. However, it is a potential sun, and some scientists speculate that after the destruction of the sun in the future, Huanxing, which is not constrained by the sun, will attract the surrounding planets to become a small solar system by virtue of its position as the leader of the solar system, and at the same time continue to absorb the surrounding matter to increase its mass, and after reaching a critical mass, it will shine and become another sun, but that will be 5 billion years later. In other words, it would take 5 billion years for a planet like the sun to be born—"

"5 billion years-" Zhou Qing was in a daze. If it really comes to the time when energy is exhausted, let alone 5 billion years, 5 years will be a kind of torment.

"Okay, let's not discuss these unhappy things, human life is too short, let alone 5 billion years, even 50 years is a long time."

"I want to know, what are the crises that humanity will encounter, or is there any way to resolve them?"

"There are many crises for mankind, in addition to the self-destruction of human beings, there are too many external threats, viruses, plagues, terminal diseases, if these viruses that cannot be treated by human beings suddenly break out in full force one day, human beings will perish. As for more specific threats, such as Xenomorphs, according to some data provided by scientists, Xenomorphs' bodies are miniature chemical factories that are perfect enough to adapt to almost any harsh environment, and their only flaw is that they cannot create. However, this situation is changing, the aliens have learned how to maintain the ecological balance, know how to control the number of races, you see this stormy prairie, species are still abundant, some animals and plants have not become extinct because of the appearance of aliens, which shows that they are doing a good job in this regard, and the basis of survival is not based on devastating destruction. It is expected that in the near future, there will be three possibilities, the first is that humans enslave aliens, the second is that aliens enslave humans, and the third is that aliens coexist peacefully with humans. ”

"Peaceful coexistence?!" Zhou Qing was suddenly so shocked that she couldn't close her mouth, she really couldn't imagine the scene of living with those black aliens.

"Actually, these three endings are the best, if there is a human to destroy the alien, or the alien to eliminate the human race, then, whether it is a human or an alien, in the end, there is no escape from the fate of extinction."

"I don't understand." Zhou Qing shook her head, she couldn't link the fate of the alien with the fate of the human race.

"This is just a general statement and a conjecture. If humans are still unable to coexist peacefully with aliens after they have evolved to the level of human intelligence, then it means that the existence of human beings is based on the extinction of other advanced lifeforms. You can imagine what would happen to the Seven Star Fields if the intelligence and technological level of the aliens reached the same level as human beings, and they fought while treating each other as a great enemy of life and death? The planet will be shattered by the cannon, the star field will become barren and quiet, the space passage will be congested with countless debris, and the surviving human beings will be confined to a small space to fend for themselves-"

"I see—"

Zhou Qing looked sideways at Liu Fei, with a hint of imperceptible respect in his eyes. In addition to the terrifying skills of this young man, his profound knowledge makes Zhou Qing, a high-achieving student, have a feeling of being out of reach, and what shocks Zhou Qing the most is Liu Fei's wisdom, his thinking is farther, more comprehensive, and his foresight does not look like the head of a mercenary group at all.

"In fact, we don't have to be entangled, even if the end of life is death, but we can enjoy the glory and wonder of life in the process."

"Yes, we know for ourselves, we have all worked hard for the land under our feet and the sky above us."

"Yes, we've all tried!"
