When Xu Liang heard this, he felt even more uncomfortable. But he still didn't say anything.

Duan Qing: "The difference between the two may be...... We raise pigs or rice in captivity just to eat, and they keep us or other civilizations in captivity so that we can develop different technologies from them? ”

"Every single race can only develop one major technology. And relying only on the strength of one's own race, it is difficult to make achievements in a wide range of technologies. Therefore, perhaps the most effective way for advanced civilizations is to captivate other races, and let these 'other' races develop technology for them! ”

"Just as pigs or rice are raised in captivity for food, the goal of captive breeding in other civilized societies is to try to take advantage of the differences in different civilized societies to develop different technology tree systems. In this way, the fundamental problem of 'incomplete technology tree points' has been solved! ”

"And, most importantly, this explanation has the added benefit of explaining that we have explained the previous tsunami, and the sudden appearance of various mutated creatures such as rabbits, ants, termites, etc.—"

"Think about it, under the ocean, there's a super-massive civilization. This civilization has been on Earth for countless years, with the potential to reach 1 billion or even 2 billion years. However, despite the fact that the underwater civilization has survived for such a long time, it has not evolved a super technology that is large enough to travel the universe. ”

"Over the course of time, they've finally discovered the same thing that we've only just learned now, and their tech tree is probably wrong, or rather, incomplete, and absolute. There must be some scientific method that they don't know at all, which can make them rush out of the earth, but the problem is that if the technology is crooked, it is crooked, and 'not knowing' can never become 'knowing' out of thin air. ”

"So, this long civilization, which has existed for countless years, decided to make an amazing attempt in order to develop!"

"They use their own extremely developed biotechnology to change their body so that they can dive!"

"Dive, dive, dive!"

"They hide beneath the bottom of the earth, above the magma, in the infinite darkness, between the earth's crust and the mantle, completely abandoning the graceful and comfortable life on the surface that they have always had, hiding their size from anyone else. It is only at some of the depths of the ocean that there is some room for observation. ”

"Their goal is to find technology, to find the technology tree of other races!"

"Since a complete scientific and technological system cannot be born by relying on it alone, can it be used by other races?"

"This way may be the way to form, or at least see 'other' technology!"

"After they hid underground, after they hid at the bottom of the sea...... And the surface of the earth, because of their withdrawal, has re-vacated the living space, so a new wave of natural selection of the fittest has begun to survive again......"

"The newly born intelligent life may be different from the technology tree of this civilization?"

"As long as it's different...... And they earned it! ”

"Because collecting different tech trees is what they intended! That is their most fundamental purpose! ”

"They hide at the bottom of the earth because they try not to disturb the creatures on the surface, in order to let the surface civilization develop naturally and produce a completely different technological system! The bigger the gap, the higher the value that can be used! ”

"Perhaps, this is the purpose of this powerful, distant civilization that has hidden itself for countless generations?"

"In the Archean 650 million years ago, there was a major Cambrian explosion of organisms, and it seems that countless different organisms appeared on Earth in just a moment! This bizarre Cambrian explosion is difficult to explain even in modern paleontology. Can we assume that this is actually because of the ancient underwater civilization, which wants to release the maximum number of different kinds of creatures to allow them to compete, develop, and finally give birth to different technological systems? ”

"The end result, as we already know through archaeology, is that the trilobites, the overlord of this ancient creature, have ruled the earth for hundreds of millions of years! I think that a super overlord like a trilobite must have some special value, and it must have been taken away by the civilization at the bottom of the sea......"

"Wave after wave, stubble after stubble, megalodons, saber-toothed tigers, ancient dragonflies, and even the famous dinosaur family...... Each ancient age has its own generational characteristics of biological overlords, or have these biological overlords developed a technological society? Or at least there is something desirable in the evolution of living things, that is, in the individual of living things. As a result, they were all collected by the huge and distant undersea civilization under the ocean. ”

"That's what that ancient civilization is aiming for?"

"But their goal must be more than that, what they want is not just a biological individual, not even a powerful biological individual, but a complete technology tree!"

"Because even the most powerful individual is just biotechnology."

"For a long time, most of the races collected by this undersea civilization can only provide biotechnology, and they are disappointed, and they understand the difficulty of obtaining the technology tree. With the exception of one occasion, they gathered chemical technology from a strange hut and mastered the method of using chemical energy, which is what we see as an explosion. ”

"But that's all, except for the biotechnology that has been refined day and night but has never been able to break through, and the chemical technology obtained by chance, they have never made an inch!"

"They've finally realized that it's extremely difficult to get any tech tree other than biotechnology!"

"They kept the overlords of civilization in various periods in captivity somewhere underground, not for food, not for fun, but for these races to evolve different technologies. They hope that these successive overlords can continue to evolve. It's been a long journey of trying, it's been a long one. ”

"At the same time, they are experimenting on the surface again and again."

"They pursue the principle of complete non-interference, but they just hope that the creatures on the surface can develop a different technological system without being affected by them."

"Finally, the harvest time has come."

"That's right, it's the final harvest! Any population of organisms that evolve on the surface of the earth is nothing more than the word 'harvest' for them. ”

"Before they can do the 'harvesting' action, they have to assess the survivability of this creature! If the creature is so weak that it can't withstand even ordinary natural disasters, then there is no need to collect it. On the other hand, if this creature has the ability, the strength of the individual creature and even the technology, and can resist super natural disasters, then they can collect this creature! ”

"So, their method of 'detecting population strength', or just ...... Unleash a super tsunami? ”

"It's like they've grown big every time in billions of years...... Because archaeology, and even the myths and legends of each place, have long told us that there was more than one monstrous flood on the earth. ”

"Perhaps, the mutated creatures we saw before, those rabbits, termites, etc., they are actually the biological overlords of a certain period on the earth before? And all are the kind of hegemons with wisdom? ”

"We've seen several, and probably more, that we haven't seen."

"These species have all chosen to be attached to the main body of this undersea civilization, or ...... 'forced' to be attached to this undersea civilization."

"Or perhaps, attaching to a higher civilization is the most correct and most likely way to survive? The most effective way to survive? Or even ...... The happiest way to survive and develop? ”

"It's like we grow rice and raise pigs?"

When Duan Qing said this, he had to continue to talk about the inferences that followed. But Xu Liang interrupted him directly!

"That's not happiness."

Xu Liang's voice was not loud, but his tone was categorical!

"That's never! Right! Not happiness! ”

"Do you know how miserable pigs are?"

Duan Qing didn't speak.

Xu Liang: "You don't know. You're a scientist, and you're very good at reasoning, so you don't know what actual creatures are like. ”

"But I know."

"Because, there are many families in my village who can raise pigs."

"The pigs raised in the family are usually slaughtered in four or five months. Do you know what slaughter is? I'll also give you a science popularization, the so-called slaughter, that is, it can be slaughtered and eaten. ”

"In other words, a pig can only live for four or five months."

"And for comparison, wild boars that grow up in the mountains can live for forty or fifty years!"

"Do you still think pigs are happy?"

"Pigs are the cleanest animals, but at home, the pigsty is the dirtiest place."

"Pigs are very intelligent animals, they have very sharp noses, and they can run away from the fence. Do you know how we do it to prevent pigs from escaping? ”

"It's simple, mash its nose."

"That way, as soon as the pig starts smelling something, its nose will hurt excruciously!"

"Such a pig can't escape."

"You just said that the number of pigs has expanded 1,000 times in 7,000 years, and you're right. Perhaps this conclusion is correct? ”

"But if I'm one billionth, if I'm an individual in that successful population, if I'm in captivity......"

"I wouldn't like to live only a few months!"

"I wouldn't like to sleep on my own!"

"I don't like to be given good food and drink, just thinking about my meat!"

"Or some kind of technology!"

"I don't want to live like a brute."

"I don't care that I'm the most populous mammal in the world! Because billions of people of the same kind live the same life as me! ”

"Because I don't want to eat, and I don't want more of my kind." Xu Liang controlled his feelings and became calm again, but his tone was more firm, "What I want is freedom." ”

"Pigs face people, that's it."

"The same is true of people in the face of higher civilizations."

"Perhaps, perhaps, the overlords of those prehistoric civilizations in the long river of history, and those hegemon-level populations that dominate the surface of the earth, have finally succumbed and become tools for the development of science and technology by undersea civilizations; It becomes a tool that lives well, but is kept in captivity......"

"But I don't want to."

"I just want to them."

"I just want to know how to take them down."

"I just need to know that."
