"Why do you have to be so mysterious?"

Lu Qingchen sneered, "I don't believe that even the fierce battle with 90% of the troops was able to grit my teeth and persevere. What else could make these iron-blooded warriors who returned home in full capacity collapse instantly. What did they discover?"

“A hub.”

Fuxi said, "Or, a switch."

"A... switch?"

Lu Qingchen was puzzled, "What kind of hub is used to control, what kind of switch is used to control?"

“The hub that controls the black wall.”

Fuxi said, "You can turn on and off the switch of the black wall in an instant - in this way, it should not be called the 'black wall', but the 'black domain' or 'black curtain', which is a dark barrier that can be switched as you wish."

These words were like a scoop of liquid nitrogen pouring into the soul, causing Lu Qingchen's soul to instantly freeze.

The same is true for Li Yao's soul, every thought and every thought falls into a stiffness.

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 soul ripples were extremely messy, and shattered vortexes bloomed, "You mean, the dark vacuum that shrouded outside our universe is impossible to measure at all. It is not formed naturally, but is caused by artificiality?

"Is it someone who deliberately extinguished the light of billions of stars, crushed all planets and cosmic celestial bodies, and will the space spanning billions of light years turn into a dark mist?

"How is this possible? How is this possible? The scale of the 'black wall' is far greater than the diameter of the huge universe where the three thousand worlds are located. No one can estimate how vast it is. Over the past tens of millions of years, countless civilizations, countless forces, and countless outstanding super powerhouses have tried to cross the black wall and rush out of the universe, but they all returned in a desperate situation or even failed!

"We once thought that the black wall was a natural barrier that could never be crossed. If it was an astronomical phenomenon generated by the universe, then that was understandable, but you actually said that the black wall was artificial and a dark barrier controlled by some kind of force? This, this is impossible, this is absolutely impossible!

"Black walls, dark curtains or black fields - whatever you call this damn thing. If it was really artificially generated, how would its builders extinguish billions of stars, cover up infinite celestial bodies, and crush tens of trillions of planets to create such a dead area with nothing!"

Lu Qingchen said more and more, and at the end, he roared hysterically.

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

Like him, Li Yaoyi wanted to whistle to the sky to vent his inner slightest feeling that cannot be described as ink.

"The specific details are like sand flying in the wind, which have all disappeared over the past few hundred thousand years. Perhaps, after I find more computing and storage units, can I recover some information?"

Fuxi still said calmly, "I only know that the technology of creating dark barriers may not be as complicated as you think. It does not need to really extinguish billions of stars and crush a planet with a hundred times more numerous. It only needs to use some method to "block" the light, heat, various radiation and high-energy particle flows they transmit, and block all information and data from being transmitted outwards.

"That is, the star system and other celestial bodies that should exist at a certain coordinate are still running in their original orbits, but their information is 'blocked', making it impossible for observers of lower levels or longer distances to find them.

"Of course, you are right. Even if you don't need to really smash billions of stars, to achieve such a large-scale "dark shielding", you still need to develop unimaginable technologies - not only can humans today be unimaginable, but even the Pangu civilization at that time cannot imagine it.

"At that time, the Pangu civilization had already mastered the technology of efficiently utilizing stellar energy. It could establish large-scale energy base stations near the stars, and even wrap a star part to form the "Kuafu Ball", and also had the ability to detonate stars and destroy the entire galaxy, that is, the "Houyi Arrow".

"However, such technology is more clumsy than the "drilling wood to make fire". Whether it is "Kuafu's Ball" or "Houyi's Arrow", they are as naive as toys for three-year-olds.

"Even according to the most optimistic estimate, the technological gap between the peak technology of Pangu civilization and the technical gap between the shady builders has at least five million years until infinite. That is to say, in the perfect state where the luck is the best, the resources are the most abundant, everyone works together, and the entire civilization is soaring and progressing, it will take at least another five million years to reach the level of the shady builders.

"Many times, the progress of civilization is not just about time accumulation. Pangu civilization has actually been established and matured, and has missed the best 'growth and development period', which is almost never possible, reaching the level of a shady builder.

"It's like a strong man who only cultivated to the foundation-building stage in his prime at the age of 120, which proves that his talent is second only to this. Even if he is given more resources and adventures, it will be difficult for him to cultivate to be above the gods in his life - do you understand what I mean?"

"I... understand. The saplings have grown crooked since childhood. No matter how fertilized or watered it, they cannot grow into towering trees that are straight upward."

Lu Qingchen said with difficulty, "Faced with such a terrifying civilization gap, no wonder the top strong people in Pangu civilization are in a state of dismay. However, who is the 'black curtain builder', and why do they block the starlight, isolate the radiation, and create such a vast black barrier."

"It's some prehistoric civilization."

Fuxi said, "Pangu civilization is not the first batch of intelligent life in our universe. In ancient times, ancient times and eternal times before the prehistoric times, there were endless intelligent life and powerful civilizations, with tides rising and falling, and birth and extinction. One of the most powerful prehistoric civilizations built a dark barrier and completely wrapped our universe - this is the information recorded on the 'hub' and 'switch'."

“It’s incredible.”

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

"certainly."

Fuxi said, "If the history of our universe is compressed into just one year, then the Pangu civilization only appeared at the early morning of the last day of 365 days, and human civilization only appeared at noon or dusk of this day. However, in the previous 364 days, how many forms of life emerged and how many brilliant civilizations were created, who knows?

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

"That is to say, the Pangu civilization has discovered some relics of prehistoric civilizations?"

Lu Qingchen said keenly, "Then you should have known the existence and power of prehistoric civilizations for a long time. Even though you didn't expect them to be so powerful, it was indeed very shocking, but it wouldn't be completely collapsed, right?"

"Yes, the existence of the dark barrier will not cause all the powerful people of Pangu civilization to collapse on the whole."

Fuxi said, "But you might as well think about it, think about it carefully, why do they do this because prehistoric civilizations built dark barriers?"

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

"That's right."

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

“Hongchao.”

Lu Qingchen's soul is colder than liquid nitrogen. "Prehistorical civilizations fear Hongchao to this extent that they would rather spend endless resources to erase the radiation and information of all the stars around them, seal themselves and their descendants and their billions of years later in the dark barrier, and they dare not rush out to fight Hongchao to the death, just because they knew that in the face of Hongchao, they would definitely, absolutely, absolutely, absolutely no winning rate of one in billions!

"Wait, there is a problem here. In a place where there should be a large number of stars and cosmic celestial bodies, a black fog will be created to wrap everything up. Wouldn't a strange black spot appear...will it really not be discovered by observers outside?"

"You can think of the dark barrier as a thick layer of eggshells, with the patterns inside and outside the eggshells being completely different."

Fuxi said, "From the inside out, the dark barrier is a star field with no resources that is extremely scarce, and from the outside to the inside, there is naturally another scene, perhaps forging a world of barren, boring, boring, and no value for exploration and hunting, which dispels the hunters' idea of ​​coming here.

"In short, the dark barrier is not a simple dark spot. In addition to hiding, it also has the function of blocking and filtering. On the one hand, it blocks the new civilizations in our universe, who are ignorant of the sky and the earth, and rushes 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 like the atmosphere can isolate ultraviolet rays.

"It can be seen from this that the dark curtain builders have put in a lot of effort to reborn civilization billions of years later.

“However, this is not the reason for despair.

"The reason for despair is that even prehistoric civilizations that are so powerful that they cannot produce a little resistance when facing the flood tide, and can only bury their heads deeply in the sand. So, how powerful should the real flood tide be?

"Now, you understand?"

"Only when the power gap between the two sides narrows to a certain scale, despair and fear will arise. Ants will never despair and fear for dinosaurs, because both sides are not at the same level at all. Ants cannot understand the power of dinosaurs at all. Even if they are stepped on by a dinosaur, they will just die in a confused and fearless manner.
