When Nan Qiyun woke up, he was already lying in a hammock. Not far from the hammock is a small wooden table. The middle-aged man wears glasses and holds a wine glass in his hand. His beard was particularly noticeable, probably because he had just been careless, and a drop of red wine had been stained on his beard and slowly flowed down his beard.

"You're awake." He saw Nan Qiyun open his glasses and cast a kind gaze.

Nan Qiyun struggled to get up from the hammock, feeling a heavy tiredness on his body, he staggered a few steps and walked to the table.

"Sit down, you're welcome," the middle-aged man picked up the wine bottle on the table and poured wine into the glass, "My name is Chen Tian." ”

"I didn't expect that there would be people in this world who could reach here like me." He looked at Nan Qiyun.

"What's your name?"

Nan Qiyun looked at the middle-aged man in front of him, tall and fluent in Chinese, except that the beard on his face did not match his appearance described by later generations, the person in front of him, judging from his appearance and environment, was indeed Chen Tian himself.

"Nan Qiyun," he pushed away his chair and sat down, "Mr. Chen Tian, why am I here now, and where did you find me?" ”

"At the exit of the outer part of the ruins building, you were wearing a wetsuit and lying at the entrance of the passage."

Chen Tian paused. "Listening to your tone, it seems to know me."

Nan Qiyun looked at the middle-aged man sitting in front of him, his eyes changing rapidly.

"As you know." His tone was slow, and every word he uttered was incomparably clear. He suddenly hesitated, if he rashly said his identity, it would be equivalent to exposing the time era he was in, which may rewrite history to a certain extent, and then cause the corresponding time paradox.

"The diving suit you are wearing seems to be a little different," Chen Tian looked at Shangnan Qiyun, "I'm an inventor, so I'm very interested in something good." ”

"Out of curiosity, I took the liberty of testing the wetsuit that had been stripped from you while you were asleep. The power of the performance was beyond my expectations. ”

"As far as I know, no one or national government organization in this world has the ability to develop decompressive submersibles, especially the ability to enter here."

"So I'm curious how you got here. At first, I suspected that there was a country or organization that had developed the same level of technology. However, in the process of in-depth analysis of the wetsuit, I noticed a strange place. ”

"What kind of wetsuit you're wearing? My monitoring instruments are unable to determine the elemental composition of the elements. ”

"The biggest problem arises in the identification of the age." Chen Tian's gaze suddenly became extremely sharp.

"I don't know if there's something wrong with my instrument." He put the dating instrument on the table and paddled it in front of Nan Qiyun. Above, a blurred number is presented on the display. Nan Qiyun could vaguely see the two numbers "24".

"Now the instrument is really broken. After the wetsuit has been identified. But I remember the last number on the monitor. Chen Tian touched his beard.

“2420。”

"If I'm not mistaken, it's time, it's 3:32 p.m. on January 10, 2102."

Chen Tian observed Nan Qiyun's expression. "Oh, I almost forgot to say it, you just fell asleep and kept saying some strange things in your mouth."

"There's a word I'm interested in, young man, can you tell me, what do you mean, 'time machine'?" Chen Tian's fingers tapped lightly on the tabletop. He took out the cigarette in his pocket, lit the fire, and exhaled a puff of smoke.

Time seems to freeze all at once. In just a few seconds, the eyes of the two people looked at each other so straight, each thinking about it.

Nan Qiyun frowned. He was thinking about how to explain it in this situation. Judging from the current situation, Chen Tian has obviously seen a slight abnormality, maybe he has made a corresponding or even completely correct and reasonable guess about all this, or it is possible that he actually knows nothing. How you want to explain it yourself has become a very critical choice. He suddenly thought of the time that Chen Tian had just told him.

According to the previous record of Chen Tian's diving operation, Chen Tian completed all the exploration operations at about 6 o'clock on January 10 and returned to the sea with a large amount of data. It was already past 3 p.m., more than seven hours longer than the recorded time. In this way, I have unconsciously affected the original historical process to a certain extent.

"Can you tell me first, why don't you go back to the surface after you've completed your survey?" The question is asked more neutrally, only vaguely indicating to the other party that he is aware of his actions, but leaving room for manoeuvre. Nan Qiyun was ready to disguise himself as a spy of a certain country at any time to disguise his true identity.

Chen Tian sighed. "Because I can't get out."

"What?" Nan Qiyun's face suddenly became extremely strange.

"I don't really understand what you mean."

The last drop of the bottle was poured into the glass. Chen Tian got up from his seat, walked to a box in the corner of the submersible, leaned down and took out a bottle of red wine.

He took a new wine glass from the shelf and placed it in front of Nan Qiyun. He expertly uncorked the bottle and poured a little red wine into the empty glass.

"Taste it. It's been decades old. As he spoke, he shook the red elixir in his hand.

"Judging by the way you look, you should know a little bit about the secrets here."

Nan Qiyun was noncommittal, he picked up the wine glass and drank it all. The bitter sensation almost made him vomit, and in their time, there were no artificially brewed wines, let alone treasures that had been cellared for decades. He had never drunk alcohol, and when he had seen people who were drunk and delirious, he was even less interested in them.

"Red wine is not drunk like this," Chen Tian couldn't help but laugh as he poured a little more into Nan Qiyun's empty wine glass, "This is my second time here." The last time I came here, I left with a lot of questions, but I finally couldn't let go of this sense of curiosity and responsibility, and I came back here. ”

The glass that was brought to his lips suddenly stopped in the air. "The second time?" In his impression, there is no relevant history to record Chen Tian's diving operations twice, and in the coalition government's historical propaganda to the people, Chen Tian discovered the prehistoric civilization on his first deep-sea dive on January 9, 2102 and made it public, and Hua Chengyu and Qi Yue never mentioned the problems of this history.

Chen Tian nodded. "The last time I was here was 10 years ago."

He pursed his lips. "It was the first time I saw this magnificent complex, and I remember the excitement and sense of accomplishment I felt at that time, I thought it was a relic of some human civilization in the world, and I became the first to discover it. Oh, and my assistant was an American. ”

"It wasn't until we actually went into the complex to inspect it that we discovered the oddities in it."

"I always have a very uncomfortable feeling in there, it stands to reason that after being silent at the bottom of the sea for so long, the atmosphere here should have been lifeless, but I always feel that there is a sense of vitality somewhere here."

"It may be abstract, but if I want to use an analogy, it feels like a nest of life, and a nest of great vitality."

"In fact, we haven't found any trace of human activity here, not even any trace of any human activity. I walked all the way to the inside of the complex, where there was a long passageway, and on both sides of the passage was a series of sculptural buildings. The shapes of those sculptures are not uniform, and they basically present different shapes. Or more precisely, these sculptures, there is no standard shape at all. To me, it's like a lump of black cotton. Then I saw the murals painted on the walls. ”

He noticed that Nan Qiyun did not show any surprise or confusion in what he said.

"You should know that the frescoes I'm talking about, the main parts of which are painted on them, are the strange things I saw on both sides of the passage. In the mural, they seem to be endowed with vitality, I am in the long mural, all the way to the inside, I see the whole process of the development of human civilization, not only that, but I also see things that do not seem to belong to the existing development process of human beings, in my understanding, the development of things described in the mural, has exceeded the existing scientific and technological level of human beings. ”

"My original idea was that this was a building site left by an ancient civilization, but after seeing the rest of the content, I had quite a lot of doubts about the original idea, besides, the main character on the mural is not a human, but something of a strange shape."

"The passage was very long, and the mural seemed to be as endless as the long passage, and finally I had to stop exploring the depths of it because the energy of the lighting installation I was carrying was about to run out."

Nan Qiyun's eyes flickered slightly. Among his own discoveries that he had just described to Chen Tian, Nan Qiyun found some discrepancies with his previous surveys of this place.

The last time he came here, the content of the mural he saw did not seem to be endless as Chen Tian described, on the contrary, he reached the end of the passage after the content of the mural ended, and was finally forced to return because he could not find the exit to continue his progress. And the last picture of the mural I saw was that the prehistoric civilization seemed to have suffered an extremely serious disaster that led to the decline of the civilization. If Chen Tian had seen this picture, then as the most important part of the mural, he must have had an impression, so there was no need to keep his mouth shut, looking at the way he described it, it seemed that he did not know the content of the mural he saw.

"During the process of returning to the submersible, for some reason, my assistant and I, who had always been full of energy at work, felt very tired, and then completely lost consciousness and collapsed in the passage to the exit of the ruins. These are all things that we don't find until we wake up. ”

"I can still vividly remember a strange dream I had during my sleep. In my dreams, I witnessed a hell on earth that made me feel creepy. That impressed me so much. Chen Tian gradually fell completely into the memory.

"Just as God in the Bible is obstinately determined to destroy humanity, which already represents an unpardonable sin, in my dreams I saw the destruction of countless lives in every corner of the earth, and the feeling was so real that it really terrified me. In the endless firelight, there were one broken wall after another, and the crying and wailing crowd scattered and fled. ”

"The black shadows, coming out of the ground, little by little, wrapped around people's necks and sent the terrified ones to death one by one. That's the real end of the world. ”

"I woke up a little earlier than my assistant, and I saw the assistant who had fallen next to me with sweat on his forehead, his face was pale, and his mouth seemed to be muttering something all the time, and I lowered my head and listened. He was praying. ”

"I woke him up. He yelled uncontrollably the moment he woke up, and it took a long time for him to come to his senses. ”

"He told me he had a dream and told me exactly what he had about it."

Chen Tian continued. "The dreams of the two people turned out to be exactly the same, and I carefully checked every detail of my dreams with him, and there was no difference."

"At that time, I felt the strangeness of the ruins I was in, and the black shadows I dreamed of were exactly what was shown on the murals. I began to wonder if these shadows were a threat to humanity. If all the contents on the mural are true, then from the perspective of civilization, the black shadow must represent an extremely advanced civilization, at least, much more advanced than human civilization. I don't dare to say for sure if they continue to exist in this world, but there is no doubt that such a situation would be absolutely desperate. ”

"After my assistant and I left the ruins at the bottom of the sea, looking down on the entire ruins building, in the golden light, I found that the composition and arrangement of the entire building resembled a huge city fortress in an ancient human building. After we returned to the sea level, we returned to Guam, Japan, on the yacht we had come from. The discovery of the seabed was then consolidated into an emergency document, which was sent to the three most powerful countries in the world at the same time, along with my assistant. ”

"Only the government from my home country has responded to the message I sent, with the help and support of the Chinese government, through coordination with the countries of the Sahara region of Africa, where I have opened an unprecedented huge underground military experimental base, I need to guard against the hidden threats that I have discovered, so I have been looking for ways to deal with these civilizations that may be bad for humanity. I figured that a fortress like that would require an equally large weapon, so I worked with the other technicians at the base to design an entirely new weapon sample. In our opinion, this is probably an unprecedented invention in human history, and it is not an exaggeration to say that it has the power to destroy the world. ”
