"Star Battleship." Nan Qiyun blurted out. The amount of information contained in Chen Tian's words was too far from what he had predicted at the beginning, and he had to start re-examining the question of ruins and prehistoric civilization. The previously discovered underground space of the "20-00" group is likely to be the military base described by Chen Tiankou. Then the huge number of starry sky warships that he had seen before, although it was unbelievable, was indeed very likely to be from Chen Tian's hand.

"You know its name?" Chen Tian showed a different expression. "This has always been the top state secret of the Chinese government, and no one has ever known about the military bases in the Sahara Desert, except for me and a few absolutely high-ranking government officials, or even that the Chinese government has built a huge underground military base in the Sahara Desert region."

"In the past ten years, with the full support of the government of the motherland in terms of funds and personnel and technology, while constantly opening up the space of the underground base, I have presided over the construction of more than 1,000 warships of the same type and performance.

"I had planned to dedicate my life to the construction of this base for the future of mankind."

"It wasn't until a month ago that I received a call from my assistant who had been with me at the site, and he told me that he had made new progress on the discovery that he had made 10 years ago. He invited me to his home in New York to meet with him. ”

"But when I got there, I saw images that I couldn't believe in my life."

"I saw him dead on the couch in his own home, a black shadow, curled up on top of him in a strange position."

"That's the shadow we saw in the murals at the site. There was a huge wound in his throat that almost cut his neck. I could see that the black mist on the shadow was slowly dissipating, as if it were evaporating steam, slowly melting into the air. ”

"Previous speculations that the Shadow is a threat have come true."

"I decided to re-examine the site of the seabed. I need to have a deeper understanding of these lives, and there must be something in them that I haven't discovered. ”

"So he announced his diving operation to the world with great fanfare." Nan Qiyun took his words.

Chen Tian nodded. "Yes, I think this time we need to let the world know about the threat of these shadows, the danger of the civilization that this building represents. I need to make it known to everyone in the world. ”

"Once again, I'm going to follow the same passage I walked through last time, and I need to know what exists at the end of the passage."

"I noticed a slight change in the passage, and at first I just felt it, but I couldn't see exactly what was the difference from the last time I came. It wasn't until I had been following the passage for a long time that I realized that the problem was the mural on the wall. The black shadow, this time in the form of a human being, appeared on the wall, it was an extremely distorted human form, and if you didn't look closely, you couldn't see the difference from before. They appear as if they were a man with a broken neck, half of his head hanging over his shoulders, and his body a blurred black, with only limbs that are vaguely spread outward. ”

Later, the content of the mural gradually changed. This time I made it to the end of the passage. Ahead was a cul-de-sac blocked by heavy walls. On the side of the picture, there is a huge fleet. ”

"It looks like an ancient sailing ship, floating in the ocean, and on the sail, there is a big 'yuan' character written on it. Around these galleons were small ships of small stature, dressed in samurai attire and carrying long swords. ”

"I don't know if you've heard about the history of the 'kamikaze'." Chen Tian's tone stopped abruptly.

The cup in front of him was empty, Nan Qiyun stood up and took the initiative to pour wine for Chen Tian. "I heard that in 1274, the Yuan Dynasty invaded Japan, encountered a hurricane on the way, and the fleet was wiped out, so Japan was spared the doom of destroying the country, out of superstition, the Japanese people believe that this is the ghost of Emperor Jimmu, a descendant of Amaterasu, to protect the Japanese people. Since then, it has been passed down almost as a Japanese faith. At the end of World War II, Japan carried out a type of suicide air raid, and those suicide detachments became known as 'kamikaze'. ”

"On the other side, around the fleet, there are huge waves several times higher than the ships. In the sky above the ship, there was an overwhelming black shadow. At the end of the scene, there are countless wrecks and corpses floating on the surface of the sea. ”

The scenes described by Chen Tian are shocking, and although Nan Qiyun has stepped into the ruins of prehistoric civilizations twice, he has never found these scenes and images as Chen Tian described. Linked to the incident when the ruins continent surfaced to the sea later, Nan Qiyun suddenly had a bold conjecture in his mind, since the entire ruins building can be moved as a fortress, then inside the building, there are also mechanisms or devices that can be moved at any time, every time everyone enters the ruins, the scenes they see will change accordingly to varying degrees, thus interfering with the judgment of the intruder.

"That was my last discovery in the ruins, and after that, no matter what method I used, I could no longer get any useful information from the ruins, after I entered the ruins, all I could see was the long passage, and the buildings that I had seen on the periphery of the ruins did not appear in my field of vision again, and the entire ruins were as if they were completely closed to me, and no longer transmitted any information to me, if the entire ruins were compared to a system, I sensed that I might have been seen by the system as an intruder to be ostracized. ”

"After many unsuccessful attempts, I finally returned to the submersible I was on, and when I was about to climb the submersible to the surface of the sea to leave here, I found that the submersible seemed to be attracted by a huge force, at first it only slowed down, and later, it stopped climbing completely, and the whole submersible seemed to be locked in a cage, trapped in the environment where it is now. In this sea area at a depth of nearly 30,000 meters, no one can leave here without relying on submersibles. Strangely, although I could not continue to climb the submersible to sea level, the submersible could still have a lot of power at the current depth, and once a certain depth reading was passed, the submersible's power began to be inexplicably limited until it finally stopped completely. ”

"The highest distance I can climb now is 29,000 meters below sea level."

In this way, Chen Tian did not leave here after that, so he did not return to the sea level, and he did not return to the human world he was in until he died. Nan Qiyun's heart suddenly felt an extreme chill. According to records, after successfully completing the exploration of the ruins of prehistoric civilization, the human explorer Chen Tian successfully returned to the sea level with the advanced technology found in the ruins, and after 20 years, the "Planet Building" project was opened. If Chen Tian was actually trapped at the bottom of the sea, then who was the Chen Tian who later returned to the human world.

"Having said so much, after all, you are probably the last person in this world to hear me speak, the words you said before unconsciously, made me very curious and very interested, I think your identity must not be simple, can you tell me, your identity?" Chen Tian pulled Nan Qiyun, who had been silent for a long time, back from his thoughts.

Nan Qiyun looked at Chen Tian's eyes for a long time, and he finally made up his mind.

"I'm from the future." As he spoke, word by word.

Chen Tian's eyes narrowed suddenly. "What?"

"To be precise, it's from the future three hundred and twenty-one years later, through the successful development of a time machine in that era."

Chen Tian was speechless in surprise for a while. In his original guess, Nan Qiyun might have been a spy or intelligence agent of one of the three countries that had previously learned about the ruins. At one point, it was even believed that Nan Qiyun's purpose was to track and investigate himself in order to obtain information about what he found in the ruins.

The atmosphere plunged into a brief silence.

Chen Tian looked at Nan Qiyun's eyes, and after a moment, he nodded unconsciously. "I see, no wonder you seem to know what I'm saying. If what you said is true, then more than 300 years later, the earth must have a very deep understanding of the ruins and buildings that I have found now. ”

Nan Qiyun shook his head. "Not exactly, one might even say that I still don't know anything."

"In our time, humanity has completed an unprecedented project, and the earth has been transformed into a six-story edifice, which is controlled and managed through the terminal system of the building. If it weren't for the events that happened later, we would have thought we were in a perfect 'utopia' era. ”

"Change?"

Nan Qiyun nodded. "Well, those black shadows appeared. We named them 'black bodies', and they began to infiltrate the human community like crazy, once humans are latent by these things, they will slowly replace their own existence, and the 'black bodies' can be transformed into the exact same form as humans by copying human genes, mixed with ordinary people. This has caused us great trouble and trouble. ”

In the later developments, some people gradually questioned the source of the building system, because in the history books, the technical source of the building system was discovered and brought out by Chen Tian, the earliest explorer of the abyss ruins of mankind, that is, Mr. Chen, you discovered and brought it out from the prehistoric civilization sites, but for the specific content of this technology, there has never been any detailed explanation and analysis of the relevant data. As a result, skeptics argue that this in itself represents the unreliability of the building system. ”

"I was negative about their doubts at first," Nan Qiyun said, "but now it seems that the origin of all this is not so simple. ”
