1. "Before talking about 'captivity', I will first talk about the class of technology. ”

Duan continued: "According to the above content of the data: for example, in the case of biotechnology, in fact, any technology is the same, it is divided into three levels, according to the amount of energy that can be controlled. ”

"The first tech class can fully utilize all the energy on the home planet. Including but not limited to wind energy, stellar light energy, mineral energy, nuclear energy, water level difference energy, temperature difference power generation, gravitational tidal energy, etc. Once it can be fully utilized, it means that the technology can use all the energy on its home planet, that is, it has reached the peak of the first level. When we humans were not hit by the tsunami, we were still very far from the peak of this first stage. But the undersea civilization, perhaps, has already been reached? ”

"The second technological class is marked by stepping out of the home planet and into space. The easiest scenario to understand is to be able to harness the full fusion energy of a star and use it for oneself to build a comprehensive intragalactic defense plan in a vast space of several hundred astronomical units. For the energy utilization of this class, there is a Dyson sphere hypothesis that can be referred to. ”

"The third tech class, the highest level, is the ability to harness all the energy within a river system! It's a terrifying concept. First of all, this usually includes all the energy of the hundreds of billions of stars in the river system, and more, plus the energy of 85%-90% of the dark matter in the river system, and finally, the gravitational potential energy of the supergiant black hole that can harness its most central mass, which is hundreds of millions of times the mass of the sun! Being able to make full use of these is the ultimate form, the level of civilization that third-order technology can achieve! ”

"The above three are the class problems of science and technology."

"Moreover, different technology tree development routes have different ways to achieve energy utilization."

"No matter which technology is developed, this level of energy utilization can be achieved, but the way to achieve it is different."

"According to the most common situation recorded in the data, that is, the development route of 'biotechnology' with the largest number of civilizations, most of them are unsustainable development in the way of microorganisms extracting minerals from the home planet. This method is difficult to last and difficult to upgrade, which is why the vast majority of civilizations have remained in, or even far below the first estate. ”

In this way, we have roughly explained the method of advancing civilization and technology. With this content as a foundation, we can move on to the issue that we just left behind – captivity. ”

"If there is a very strong civilization, such as biotechnology at a tech tree point, and a civilization with a second-order stratum, and another techno-tech tree is discovered with materials science, but there is only a first-order civilization...... You can think about it, what will this second-order biotechnology civilization do? ”

Xu Liang thought for a moment.

In fact, it's not complicated, if it's according to the law of the dark forest, it's definitely a two-way foil thrown over, no, it's skewered, it's definitely not left alive, either broadcast the direction, or directly give a devastating blow. In "The Three-Body Problem", the suppression of low-level civilization by high-level civilization is absolute and unconditional.

But if it's according to the law of dense forests......

"According to the law of dense forests, biotechnology and materials technology cannot be developed at the same time. Then the biotechnology civilization with a higher energy level, when this material technology civilization is discovered, maybe its power will be stronger, or it may be able to destroy this first-level civilization, but the more advantageous way is to find ways to obtain its scientific and technological capabilities! ”

"You have to be careful, starting a war may be won, but it will definitely pay everyone, and there will be no benefit! If you want to maximize your benefits, the best way to get its technology is to get it! ”

"That is, captivity!"

"They will try to do everything they can to obtain all the information of this material technology civilization and do their best to learn! And it's definitely not a wave of your hand to kill this young material technology civilization! ”

"Between the civilizations of the universe, if there is a restriction that the technology tree cannot develop at the same time, it is not the law of the dark forest that is followed, but the law of the dense forest!"

"Between civilizations, it is no longer life and death, but a development relationship similar to 'symbiosis'. This is the essence of the law of dense forests! ”

Duanqing's logical reasoning was very smooth, but the keen Lao Xu was quite a very obvious problem.

"Why don't you kill chickens for eggs?"

Xu Liang's idea is very straightforward, since that biotechnology has evolved to the second order, then ...... Directly kill the so-called material technology, and then learn and develop it yourself, isn't it over?

What a simple thing!

"Everybody wants to, but they can't do it." Duan Qing said, "A race is only sensitive to its innate technology, and can be discovered, for other technologies, it can only use its results mechanically, and it is extremely difficult to learn its principles, let alone improve or integrate the advancement." ”

This is also the basis of the law of dense forests, which can only be realized under the premise that the technology trees are not interconnected. And the information I got shows ......" Duan Qing shook the information in his hand again, "The actual situation is the same." ”

"The vast majority of known civilizations other than our human beings only have the ability to research one kind of technology, and there are too many of them to be able to do so. They can be extremely proficient in their own technology, but in other fields, these civilizations are like idiots! ”

"It's as if we humans have become accustomed to connecting our mobile phones to IFI to access the Internet. But for an alien who has never been exposed to the Internet civilization, do you know what it means to connect a mobile phone to IFI with a light finger......

"It means building signal towers, building base stations across thousands of kilometers, building power plants, building signal relay devices, building mobile phone factories, building chip factories, building material factories, building ...... All in all, for the aliens to be completely rebuilt, what is needed is a complete set of modern Internet industrial system, which is completely unimaginable for them! You can't make it!"

"Not to mention Shannon's "The Mathematical Principles of Communication", Turing's "Computer", von Neumann's "Game Theory and Economic Behavior", and UUUU's IIII are supported by these theories!"

"These are the greatest geniuses of mankind, developed with the most incredible creative ability, and the scientific treasures that cannot be copied by predecessors!"

"So, going back to the example just now, what should a second-order biotechnology civilization do if it can catch a first-order civilization in the universe that happens to be a non-biotechnology civilization?"

"Keep it in captivity!"

"Give it good enough conditions to let it develop!"

"Until the day comes when it reaches 'transcendence'!"

Xu Liang captured a key word: "Until what?" How long has it been in captivity? ”

"Captivity to the last moment, that is, when the second-order biotechnology civilization reaches the 'transcendental' level."

Xu Liang: "'Transcendence' class? You've mentioned it several times. What exactly is this concept? ”

Duan Qing: "The information is also vague, because the cracking progress ends here." And then the deeper cracking progress, now this kind of small computer can not afford it. But although I can't crack it, I can roughly guess the concept of this 'transcendental' class...... Perhaps, this transcendence has nothing to do with the amount of energy control, but with interdisciplinarity, perhaps the creation of new disciplines! Do you know? If my guess is correct, then our human civilization has a natural and huge advantage! ”

"We are born to transcend the level!"

"Whether it's a fully open science and technology tree, or interdisciplinarity, it's not a problem for us humans!"

"We have enough theoretical foundation, and we have an almost sound tech tree!"

"We have a full range of technologies from the most fundamental mathematical language to the most practical aircraft construction!"

"Although you can't see it at all at a low level, it's a full set of technology!"

"Full set!!"

"What other civilizations dream of, the attributes that need to be developed to the third-order apex to be acquired, we humans have had it from the very beginning!"

"We humans are the lucky 0.0001%!"

"Of course, maybe it's the beginning of misfortune."

"Because this means that we are likely to be captive by the undersea civilization."
