Li Yao was silent and nodded in his heart.


    In fact, this truth of the voice is also reflected in the history of human civilization in Pangu universe, that is, the chaos of the ancient times, including the tragedy of the "living fossil" ancient holy world.


    No power can be obtained without paying any price. Fate has already marked the price for each power. Those seemingly easy to obtain power may have to be exchanged with more precious things - organization, social order, desire for exploration and curiosity.


    Fortunately, the human civilization in Pangu universe, including the Pangu civilization before human civilization and the 100 ancient civilizations before Pangu civilization, is not the first generation of original civilization in the strict sense, but the descendants of the original civilization.


    On the one hand, they can find the remains of the previous generation of civilization from the depths of the earth and the vast sea of stars, learn valuable lessons and avoid repeating the same mistakes; On the other hand, deep in their genes, they originally contain archaic memories from the Yuanshi people. Although most of the time, these ancient memories are mottled and vague fragments, they are enough to stimulate the instinct of intelligent life, and naturally form a complex sociality and high degree of organization.


    Therefore, these "secondary civilizations" can develop quite powerful civilizations in the environment with rich aura, but they inevitably have to take many detours - for example, the "collapse of ancient civilization" and the "thirty thousand year Dark Age" of human beings, and even today''s various evils of the covenant alliance and the human Empire, all of which have to be attributed to "too great individual differences, The strong are too strong and the weak are too weak.


    Those original civilizations, which have neither the remains of previous civilizations to excavate nor the "organizational instinct" hidden in their genes, suddenly get inexhaustible and inexhaustible power. It''s just like seven or eight year olds who have got a huge heritage and lack adult discipline, will only spend recklessly and almost never fail to learn.


    "Of course, psionic power is one of the most precious resources in the universe, but only a highly mature civilization with its own" Tao mind "has enough qualifications to drive it, not to be enslaved by it."


    The voice continued, "it is because without the help of psionic powers that we can inspire all our enthusiasm, wisdom and courage to transform our planet and understand the universe beyond the planet with our hands, sweat and blood.


    "We have had the first industrial revolution, the second industrial revolution and the third industrial revolution.


    "We''ve discovered the laws of celestial bodies, and we''ve also discovered molecules, atoms, and structures smaller than atoms.


    "We discovered electromagnetic waves and knew how to use radio; We have conquered mountains and seas, and countless kinds of bacteria. We even know how to drive molds to cure fatal diseases; We believe that the road of science and technology is infinite, and infinite science and technology will eventually make us become the gods of ourselves and the whole sea of stars.


    "Of course, the rapid development of technology and the sudden expansion of civilization also brought about Crazy ambition and bloody killing. In the first 50 years of the 20th century, we launched two world wars one after another. If the main battlefield of World War I was only limited to one continent, then the death storm of world War II really swept the whole parent planet.


    "It was two extremely brilliant and cruel wars. People who were lack of spirit and had no power to bind chickens could release more terrifying destructive power than practitioners. Countless tons of steel and explosives fell like torrential rain and could instantly destroy a big city with hundreds of thousands of people.


    "Especially at the end of the Second World War, we used a weapon called" atomic bomb ", which involves the mystery of material annihilation and energy explosion. On the surface of a planet with an atmosphere, it is more terrifying than the main gun of a star ship.


    "However, on the one hand, war is the devil that destroys civilization; on the other hand, it is also the catalyst that promotes the rapid development of civilization. The new technologies and new ideas born in the two world wars, including the new systems born from innumerable destroyed old systems, all promote the explosive development of our civilization in the last 50 years of the 20th century, It''s going forward like a storm.


    "After the end of the Second World War, but more than 20 years, that is, on July 21, 1969, our primitive and simple starship boarded the only satellite of the parent star for the first time and took the first step of conquering the sea of stars."


    With the sound, a new picture appeared in Li Yao''s mind.


    Three bulky and clumsy astronauts in white spacesuits and star spangled flags are bouncing on the surface of the moon. In the slightly low and noisy background sound, there is also the voice of one of the astronauts:


    "... this is a small step for me, but a big step for mankind."


    Of course, the astronaut said this in English, which is the "magic language" understood by Lee.


    "The cruel destruction of the Second World War and the cold war that resulted in the confrontation between the two powers not only gave birth to space technology and the study of the universe far beyond the limits of our civilization, but also awakened the ancient nation with the largest population in our civilization. After hundreds of years of silence, this ancient civilization standing in the East regained its vitality, The most powerful initiative and creativity. "


    The voice said, "the last 50 years of the 20th century to the first 20 years of the 21st century are almost the golden age of the fastest development of our civilization. Almost every year, new technologies and research achievements come out. Almost every 10 years, the whole civilization takes on a new look. In 1950, it was still a fancy computer for most people. After 60 or 70 years, it is still a dream computer, It can be worn on people''s wrists and become an indispensable production tool and life partner for everyone. People even begin to imagine the birth of artificial intelligence in the next century.


    "However, the beautiful dream suddenly broke like a golden soap bubble. Our big bang of technology met the physical limit and was forced to step on the brake. In the third decade of the 21st century, we encountered stagnation and setbacks in all fields, and hardly found anything valuable.


    "With the stagnation of technology, a series of maladies and fatal defects burst out from the depths of our civilization.


    "The super Matthew effect brought about by global networking has made the gap between the rich and the poor even wider and the society more fragmented.


    "The population explosion brought about by advanced medical technology, but the lack of a good education system and enough jobs, makes the vast majority of the population become" ineffective population "or even" negative population ", and becomes a burden to civilization.


    "The destruction of the environment and the lack of resources make the living environment of the vast majority of people worse and worse, and the advent of sophisticated weapons and even unmanned weapons makes the less developed countries more unable to resist the first developed countries, which also leads to the prevalence of extremism and a series of terrorist activities.


    "If we say that these problems are" chronic diseases "and can be solved slowly in the process of civilization development, then when the great forces representing two completely different thinking logics and economic systems collide in our civilization, the whole civilization will immediately fall into catastrophe.


    "Everyone wants peace, not war.


    "However, you should be very clear that when the external expansion of a civilization encounters setbacks, the known world is 100% explored, all resources will be exhausted, and the road of technological upgrading will also be blocked. There is no other way to go except to fall into the desperate situation of" Involution "and kill each other.


    "First there were trade frictions, then there were proxy wars, and then there were small-scale and low-intensity skirmishes... A series of warm-up, testing, threats and intimidation lasted for 20 years. When both sides were very clear about each other''s strength and determination, the third world war finally broke out.


    "In our civilization, there was once a wise scholar who said," I don''t know how the third world war started. I only know that the fourth World War must have been carried out with stones and sticks. ".


    "The intensity of the third world war is far more than 100 times that of World War II a hundred years ago, even more than everyone''s imagination at that time. Before the war, everyone was very optimistic that with the progress of technology, especially the popularity of supercomputers and armed UAVs, it would be a" clean war "and a" bloodless war. ", It was even another low-intensity bravado and routine friction between the two sides, until one after another, strange mushroom clouds rose over their heads, devoured them instantly and turned them into burning skeletons.


    "The Third World War, which lasted for 30 years, is the longest and cruelest war in the history of our civilization and has profoundly changed our civilization.


    "Especially in the late period of the war, with the complete abandonment of the parent planet, all kinds of extremism and terrorism pestilence continued to emerge, and all kinds of immature biological and chemical weapons, virus weapons and even genetic weapons were released without fear, which made us feel the fear of" civilization extinction "for the first time.


    "Perhaps, the growth of every civilization is like this. If we do not encounter a" cataclysm "that is likely to destroy the whole civilization, we will not know the value of peace and unity.


    "Even though some survivors know the importance of peace and unity, the three decades of blood feud and the white and black tombstones piled up with hundreds of millions of corpses have become a natural moat and a high wall between the two sides.


    "- if there had been no accident, our civilization would have died in infancy with such shame and sorrow.


    "But since you can hear our voice, even your existence itself, represents the coming of some kind of" miracle ".


    "In 2068, the" miracle "- the first meteorite in the rain, which is about to completely destroy the earth in a hundred years, passed through the solar system, tore up the atmosphere, and hit our barren home."
