"Why so mystifying?"

Lu Qingchen said with a sneer, "I don't believe that even the fierce battle which has lost 90% of the troops can stick to it. What else can make these full loaded soldiers collapse instantly? What have they found?"

"A hub."

Fu said, "or a switch."

"A... Switch?"

LV Qingchen was puzzled, "what hub to control, what switch to control?"

"Control the hub of the black wall."

Fu Xi said, "the switch of the black wall can be turned on and off instantly. In this way, it should not be called" black wall ", but" black area "or" black curtain ", which is a dark barrier that can be turned on and off at will."

These words, like a ladle of liquid nitrogen poured into the spirit, make LV Qingchen's spirit instantly frozen.

The same is true of Li Yao's spirit. Every thread of thought and every thought is rigid.

They were all immersed in great confusion and shock, and spent a long time chewing and digesting Fuxi's words.

"You, what did you say?"

Lu Qingchen's spirit waves are extremely messy, bursting into tiny whirlpools. "Do you mean that the dark vacuum enveloping our universe is not natural, but man-made?

"Is it someone or someone who deliberately extinguishes the brilliance of hundreds of millions of stars, smashes all planets and celestial bodies in the universe, and turns the space spanning hundreds of millions of light years into a dark fog?

"How can it be, how can it be‘ The scale of the "black wall" is far larger than the diameter of the huge universe where 3000 worlds are located. No one can estimate how vast it is. For thousands of years, countless civilizations, countless forces, and countless outstanding super powers have tried to cross the black wall and rush out of the universe, but all of them have been defeated or even lost!

"We used to think that the black wall is a natural moat that can never be crossed. If it is an astronomical phenomenon generated by the universe, it's understandable. But do you even say that the black wall is man-made and a dark barrier controlled by some force? It's, it's impossible, it's impossible!

"Black wall, black curtain or black area - whatever you call this damned thing, if it is really artificially generated, how can its builders extinguish billions of stars, cover up infinite celestial bodies and smash billions of stars to create such a dead area with nothing!"

The more Lu Qingchen said, the more he looked. At the end, he roared hysterically.

He used this crazy roar to hide his shock and panic.

Like him, Li Yao wanted to roar up to the sky to vent his inner feeling of insignificance.

"The details, like sand in the wind, have all disappeared in the past several hundred thousand years. Maybe I can recover some data after I find more computing and storage units?"

Fuxi still said calmly, "I only know that the technology of creating a dark barrier may not be as complicated as you think. It doesn't really need to extinguish hundreds of millions of stars and smash hundreds of times more planets. It just needs to use some method to" shield "the light, heat, various kinds of radiation and high-energy particle flow they transmit, and block all the information and data from being transmitted outward.

"That is to say, the stellar system and other celestial bodies that should exist in a certain coordinate are still running in their original orbit, but their information is" blocked ", so that lower level or distant observers can not find them.

"Of course, you're right. Even if you don't really need to crush hundreds of millions of stars, to achieve such a large-scale" dark shield ", you still need technology that is so developed that it's unimaginable - not only for today's human beings, but also for Pangu civilization at that time.

"At that time, the Pangu civilization had initially mastered the technology of efficient utilization of stellar energy. It could build large-scale energy base stations near the stars, even wrap part of a star to form a" Kuafu ball ". It also had the ability to detonate stars and destroy the whole galaxy, that is," Hou Yi's arrow. ".

"However, this kind of technology is inferior to that of the" black curtain builder "and worse than that of" drilling wood for fire ". Both" Kuafu's ball "and" Hou Yi's arrow "are as naive as toys of three-year-old children.

"Even according to the most optimistic estimation, the technological gap between the peak Technology of Pangu civilization and the dark curtain builders is at least five million years to infinity. That is to say, under the perfect condition of the best luck, the most abundant resources, all people working together, and the rapid development of the whole civilization, it will take at least another five million years to reach the level of the dark curtain builders.

"In many cases, the progress of civilization does not depend on the accumulation of time alone. In fact, the Pangu civilization has been shaped, matured, and missed the best" growth and development period ". It is almost impossible for it to reach the level of black curtain builder.

"It's like a strong man's cultivation reaches the foundation stage at the age of 120, which proves that his talent is second only to this. No matter how much resources and adventures he is given, it will be difficult for him to cultivate above the spirit in his whole life - do you know what I mean?"

"I understand. The saplings have been crooked since childhood. No matter how much fertilizer and water are applied, they can't grow into towering trees."

Lu Qingchen said, "in the face of such a terrible civilization gap, it's no wonder that all the top powers of Pangu civilization are lost. It's just who are the" black curtain builders "and why they want to shield the starlight and radiation to create such a vast black barrier."

"Some prehistoric civilization."

Fuxi said, "the Pangu civilization is not the first batch of intelligent life in our universe. In ancient times, Archean times and ancient times before the flood and famine, there were endless intelligent life and powerful civilization. The tide rose and fell, life and death. One of the most powerful prehistoric civilizations built a dark barrier, To wrap our universe completely - this is the information recorded in "hubs" and "switches."

"It's incredible."

Lu Qingchen said, "did Pangu civilization have such a clear understanding of prehistoric civilization?"

"Of course."

Fu Xi said, "if we compress the history of our universe into just one year, then Pangu civilization will appear in the early morning of the last day of 365 days, and human civilization will appear in the noon or dusk of this day. However, how many different kinds of life have sprung up and how many splendid civilizations have been created in the previous 364 days, Who knows?

"Human civilization draws nutrients from the remains of Pangu civilization, and Pangu civilization also gets enlightenment from the remains of prehistoric civilization. This is the true meaning of civilization inheritance."

"That is to say, some traces of prehistoric civilization were excavated in Pangu civilization?"

Lu Qingchen said acutely, "then you should have known the existence and strength of prehistoric civilization for a long time. Even if you didn't expect that they would be so strong, it's really shocking, but it won't collapse completely?"

"Yes, the existence of the dark barrier alone will not make all the strong of Pangu civilization collapse."

Fuxi said, "but you might as well think about it, think about it carefully, the reason why prehistoric civilization built the dark barrier - why did they do it?"

Lu Qingchen pondered for a moment, and the trembling of his spirit became more and more obvious: "hide, they want to hide themselves, they are avoiding something, some extremely dangerous, absolutely irresistible enemy, so they want to hide themselves deeply!"

"That's right."

Fuxi said, "then you might as well guess again, what are they afraid of, what are they avoiding?"

"Flood tide."

Lu Qingchen's spirit is colder than liquid nitrogen. "Prehistoric civilization was so afraid of the flood tide that they would rather spend infinite resources to wipe out the radiation and information of all the stars around them, seal themselves and their grandchildren in the dark barrier, and dare not rush out to fight against the flood tide, just because they know that in the face of the flood tide, I absolutely, absolutely, absolutely have no one in a billion winning rate!

"Wait a minute, here's a question. In the place where there should be a large number of stars and celestial bodies in the universe, if you make a black fog to wrap everything up, won't there be a strange black spot that won't be discovered by the outside observer?"

"You can think of the dark barrier as a thick eggshell, and the pattern inside and outside the eggshell is very different."

Fu Xi said, "from the inside to the outside, the dark barrier is a star field with nothing and extremely scarce resources. From the outside to the inside, there is another scene. Maybe it forges a barren, boring, boring world without any value of exploration and hunting, which dispels the idea of hunters coming here.

"In a word, the dark barrier is not a simple black spot. In addition to hiding, it has the function of blocking and filtering. On the one hand, it can block the new civilization in our universe from rushing out to seek death. On the other hand, it can also block and filter a large amount of harmful information transmitted from the outside world, just as the atmosphere can block ultraviolet light.

"It can be seen from this that the builders of the black curtain have put a lot of effort into the new civilization hundreds of millions of years later.

"However, this is not the cause of despair.

"The reason for despair is that even prehistoric civilization, which is so powerful that it can't produce any resistance in the face of flood tide, can only bury its head deep in the gravel. Then, how powerful should the real flood tide be?

"Now, do you understand?

"Only when the power gap between the two sides is narrowed to a certain scale, will there be despair and fear. Ants will never have despair and fear of dinosaurs, because the two sides are not at the same level. Ants simply can't understand the power of dinosaurs. Even if they are trampled to death by dinosaurs, they just die confused and fearless.

"Only when there is a reference object, a reference object that can be understood by ants, can they realize the power and tyranny of dinosaurs, that is, how vast, dangerous and cruel the world is, and that it can never be the master of the world. Its destiny is to be ruled by all kinds of powerful beings, Step on your feet again and again
