"Isn't there a way to crack the password?" Liu Xing was a little puzzled.

"I've tried everything I can think of, but it didn't work. Dr. Zhao Cong's face showed a rare look of doubt, "I have been mixed in the information field for more than 30 years, and I have never seen such a sophisticated, complex, and strange cryptographic system!"

Liu Xing asked, "Dr. Zhao, could it be that we are standing too close and interfering with the signal of the password?"

Dr. Zhao Cong shook his head: "We didn't receive any signal at all, the principle of this cryptosystem is beyond my understanding, and all detectors and scanners are ineffective." I have a feeling that the technology employed by the cryptography system of this coffin is far beyond our time. ”

"How is it possible?" Liu Shiming browled her eyebrows......

Dr. Zhao Cong looked helpless: "I know it's unreasonable to say this, but the principle used in the cryptographic system of this coffin is definitely not the principle that we are familiar with in our time, otherwise, I won't be able to find a clue." ”

Pointing to the touch screen on the surface of the coffin, Dr. Zhao Cong reminded, "Haven't you noticed that the material on the surface of the coffin is very special, not an ordinary LCD screen, let alone any kind of material we are familiar with." You can ask another material expert to identify, there must be something wrong with the material of this crystal screen, I suspect that it may be a more advanced material than the ultra-high molecular weight polypeptide polyformiminated phenolic reverse chain super-edge non-magnetic microconductive separation membrane. ”

Liu Xing's eyes were round, and he was curious: "Dr. Zhao, what did you just say about ultra-high molecules, peptides, anti-chains, and membranes, what is that?"

"Ultra-high molecular weight polypeptide polyformyl imimidated phenolic reverse chain super-edge state non-magnetic microconductive separation membrane, which is a new type of ultra-high molecular microconductive material that Huaxia Academy of Science has invested 4 billion yuan to develop, is used to solve the problem of missile ...... Forget it, you little devil doesn't understand. ”

Dr. Zhao Cong continued, "In short, the material of this coffin is extraordinary, and it is likely to have the function of collecting energy. The coffin has been buried underground for an unknown number of years, but it still works freely, and its energy source is probably maintained by absorbing geothermal and geokinetic energy. There are many other strange phenomena like this, and they are so abnormal that I suspect that the technology used in this coffin may be beyond our time. ”

Everyone looked at each other, and their minds couldn't turn for a while, beyond the current era, what does it mean?

"If this coffin is really beyond our time, it can't have been buried by humans hundreds of years ago. Professor Juan frowned, full of doubts, "So where did this coffin come from, who made it, and what is the "Legend of the Condor Heroes" mentioned in the coffin?"

Everyone was silent for a while, and Dr. Zhao Cong was also in deep thought.

Liu Shiming's beautiful eyes turned, she remembered something, and said, "Could it be a prehistoric civilization?"

"Prehistoric civilizations?"

Professor Juan and Dr. Zhao Cong were both stunned for a moment, and Professor Juan said, "You mean that this coffin may have been built by ancient humans?"

"That's right!" Liu Shiming said, "In the scientific community of Huaxia, there has always been a speculation that human beings have existed on our planet for tens of millions of years, and they, like us, have established a high degree of civilization. Later, for unknown reasons, these ancient humans disappeared from this planet, and the inheritance of civilization was disconnected, returning to the barbaric age. It wasn't until tens of millions of years later that a second generation of humans appeared on this planet and created a new civilization, which is what we are now. ”

Speculation about prehistoric civilization has always been a mystery in the scientific community of China, some scientists believe that ancient human civilization existed on this planet tens of millions of years ago, while others think that this is nonsense.

Since no conclusive evidence of prehistoric civilization can be found, the existence of prehistoric civilization has never been conclusive in the Chinese scientific community.

"If this coffin was built by humans tens of millions of years ago, it is undoubtedly a proof that there was a prehistoric civilization on this planet. ”

Liu Shiming further analyzed, "From another point of view, it is precisely because this coffin was built by ancient humans of prehistoric civilization that the construction materials and cipher principles used in it are incompatible with our times. As for the "Legend of the Condor Heroes" mentioned in the coffin, it may be a book circulated by ancient humans tens of millions of years ago, and it does not belong to our era at all. ”

Liu Shiming's words made everyone present stunned, and this information was true enough to subvert their worldview.

"If this coffin is really a product of prehistoric civilization, then its value will be immeasurable!"

Professor Juan said excitedly, "It seems that we need to escalate this matter immediately and deploy more experts in various fields to conduct a comprehensive assessment of this coffin." ”

Everyone agreed.

……

Since the value and complexity of the coffin was beyond the reach of the others, it was decided that they would leave the tomb at the bottom of the lake and return to the surface together.

They originally wanted to move the coffin back to the ground, but the coffin was too heavy to move at all, so they had to wait for the police to find a way.

At twelve o'clock in the evening, the summit of Yufeng Mountain.

The moon is bright in the sky, and the mountain wind is blowing.

On the shore of the natural lake, a bonfire was lit, and more than a dozen people were sitting around, in addition to Liu Xing and Liu Shiming, there were also experts and scholars such as Professor Juan and Dr. Zhao Cong.

After tossing for most of the day, everyone was hungry, eating the boxed lunch of two meat and two vegetables provided by the Mingxing Hotel, drinking mineral water, and talking about the coffin with great interest.

Although it is not yet possible to determine that the coffin is a product of prehistoric civilization, to everyone's excitement, this coffin is clearly not an ordinary coffin.

"What do you think the ancient humans of prehistoric civilizations were like?"

Dr. Zhao Cong touched his bare head and said, "They can build such a strange coffin material and design such a sophisticated cryptographic system, maybe they have three heads and six arms, like a monster." ”

Liu Shiming said: "I think the people of prehistoric civilization should look very similar to us, or even exactly the same. You think, the words displayed on the screen of the coffin are no different from the words of our Huaxia Kingdom, which shows that we should have an inseparable relationship with the human beings of the prehistoric civilization. ”

Liu Xing held a boxed lunch, took a bite of braised chicken thigh, and asked: "If there is really a prehistoric civilization, then why did the prehistoric civilization disappear from this planet?"

Professor Juan munched on green vegetables and said, "I think the reason for the disappearance of prehistoric civilization may be related to the book "The Legend of the Condor Heroes". ”

Liu Xing unscrewed the cap of the mineral water bottle and asked, "Old Hu, why do you say that?" opened his mouth and took a sip of water.

Professor Juan sank and analyzed: "According to my guess, the 'eagle' in "The Legend of the Condor Heroes" should be a kind of fierce beast of prehistoric civilization, it is huge, has the ability to fly, and its wings may be five or six meters long, which is aggressive. The Eagle Beast may be an ancient beast of mutations, and they attack ancient humans. In order to protect their homeland, ancient humans fought a fierce battle with the eagle beasts. Humans are supposed to use weapons like cannons to bombard Condor beasts like crazy. In this battle of bombarding the Condor Beast, many singing and crying Condor heroes appeared among the human race. Someone recorded the heroic deeds of these bombardment condor beasts, so there was the book "The Legend of the Condor Heroes"......"

"Poof—"

Hearing this, Liu Xing really couldn't hold back, and a mouthful of mineral water sprayed out directly, splashing two meters away.

"Imp, what are you spraying, am I not right?" Professor Juan blew his beard and glared.

"No, I choked on the water. Liu Xing said.

"Ah Xing, drink slowly, and no one will rob you. Liu Shiming said softly.

Wiping his mouth, Liu Xing turned his mouth and asked: "Lao Hu, according to what you said, isn't "The Legend of the Condor Heroes" a historical book that records the human wars tens of millions of years ago?"

"It's not impossible!"

Professor Juan went on to analyze, "The battle between humans and eagle beasts can be quite tragic, and many humans have died in the battle. Didn't the coffin's password system ask who the protagonist of "The Legend of the Condor Heroes" was? According to my guess, the protagonist of "The Legend of the Condor Heroes" could be the leader of the Condor Army. Tens of millions of years ago, ancient humans formed the Condor Army in order to fight with the eagle beasts, and the leader of the Condor Army may be a very clever figure, who has made great achievements and shot a large number of eagle beasts, and he naturally became the protagonist of "The Legend of the Condor Heroes". ”

Liu Xing picked up a piece of braised pork belly, put it in his mouth, chewed it twice, and said: "If "The Legend of the Condor Heroes" is really as you said, it tells the history of the war between humans and eagle beasts, then who won this war in the end?"

"I estimate that the casualties on both sides should be very heavy, and it is even possible that humanity will become extinct in this war, leading to the disappearance of human civilization tens of millions ......of years ago," Professor Juan said.

"I'm against it. Dr. Zhao Cong wiped the sweat from his head and interrupted, "Tens of millions of years of ancient humans were able to build such advanced coffin materials and design such an exquisite cryptographic system, and their intelligence level is definitely not below us. I think that prehistoric humans must have defeated the eagle beast, and as for the problem of the disappearance of prehistoric civilization, there should be a deeper reason. ”

"Are you thinking too much?" After eating the box lunch, Liu Xing burped and reminded, "Things may not be so complicated, "The Legend of the Condor Heroes" may just be an ordinary novel. ”

"What do you know, little ghost?"

Professor Juan said, "Whether it is scientific exploration or archaeological research, we must make bold assumptions, carefully demonstrate, and cannot be limited to fixed thinking and logic, and our thinking must be open." The reason why I say that "The Legend of the Condor Heroes" is related to prehistoric civilization is not a guess. You remember, the Chinese Institute of Biology found an ancient animal fossil in the western desert last year, it is said that it is a fossil of a giant beast, the body is eight to nine meters long, with sharp teeth, and a pair of thick wings, which may be the "eagle" mentioned in "The Legend of the Condor Heroes" ......"

"I have a new idea, will there be a way to deal with the carving beast hidden in this coffin, so the ancient humans used "The Legend of the Condor Heroes" as the password of the coffin?"

"It's a bit of an interesting idea, but I think there's another possibility, the Legend of the Condor Heroes is likely to be a Bible-like holy book of ancient humans, with many myths, legends, and gods ...... the book."

……

Professor Juan, Dr. Zhao Cong, and more than a dozen archaeologists were gushing about the analysis, and as the discussion deepened, the book "The Legend of the Condor Heroes" became more and more mysterious, involving the fate of prehistoric civilizations and even the origin of human life.

It may sound like nonsense at first, but it makes sense to listen to it a few more times.

Liu Xing was also wondering in his heart, what was hidden in this coffin?

What does it have to do with "The Legend of the Condor Heroes"?

No, I'll have to take a look.

"Sister, my schoolbag has fallen into the tomb at the bottom of the lake, I'll go get it. At this time, Liu Xing, who had already eaten, stood up and said.

"In the tomb, Ah Xing, I'll accompany you to ......"

"No, I'll just go by myself and I'll be back right away. ”

"Then be careful, don't slip. ”

"Understood. ”

After speaking, Liu Xing left in a hurry, said goodbye to everyone, walked quickly to the shore of the natural lake alone, and ran wildly towards the tomb at the bottom of the lake along a path that he had stepped on before......
