When the term "unknown civilization relics" was brought up by Li Yunfan, Zhao Lan covered his mouth in surprise, his face full of shock: "Not ...... Unknown civilization relics? ”

"Yes." Li Yunfan nodded lightly, his face full of sighs: "It is a relic left by an unknown civilization there." Our human civilization has been entangled in whether it is the only one in the universe, and has been committed to finding an extraterrestrial civilization, but who would have thought that there is a ruins of an extraterrestrial civilization in our solar system. ”

"This, how is this possible? Are you saying that because there is a remnant of an alien civilization in the Jupiter system, in order to keep this secret, and in order to prevent the danger that this relic may bring, the human government will choose to conceal the landing on the Jupiter system? ”

"That's about it." Li Yunfan spread his hands: "Of course, the government can't stop me." I relied on my own accumulated strength to go to the Jupiter system, found a second relic in the orbit of Jupiter in the place that the teacher said, and found the black hole in that ruin, and brought it back to Earth. I'm sure the government is now conducting a search for the Jupiter system, and the Jupiter exploration plan will only be approved once it is confirmed that all possible ruins are in our hands. ”

"The ruins I found are not the same as those controlled by the human government, but it's almost certain that they belong to the same alien civilization. According to my own estimates, if we can continue to develop at the current rate of technological development, it will probably take another 300 years for us to catch up with the technological level of that civilization. ”

Three hundred years is a short time for an entire civilization, even so short that it is somewhat inconspicuous. If you measure it by the gap of 300 years. It seems that the technological gap between the civilization of the earth and the unknown civilization is not that big. But Zhao Lan knew that this was not the case. It's like counting from now, three hundred years ago, it was probably Zhao Huasheng's era. In the midst of that era. Human civilization has exhausted the power of all civilizations by building a small base on the moon, but what about the current human civilization? It is even possible to build a big city on Mars. And that's just the most obvious progress, and the rest of the place, space elevators, Earth and Martian ports, super-massive and rapid underground transportation networks, flying instruments, aerospace carriers, and so on, are literally heaven and earth compared to three hundred years ago.

Moreover, the speed of scientific and technological development of human civilization has been accelerating, so what will it look like for human civilization to develop for another 300 years? Zhao Lan didn't dare to imagine. But now Li Yunfan said that the technological level of the unknown alien civilization that left that unknown ruin. It is probably 300 years more advanced than the civilization of the earth.

It is completely understandable that civilizations that are 300 years ahead of Earth's civilization have created artificial black holes.

But there is an important question here, that is, how old is this site? If this relic is 10,000 years old, or even 100 million years old, then how terrifying is the current technological level of that civilization?

Li Yunfan seemed to see the confusion in Zhao Lan's eyes, so he replied, "I have already measured the history of that ruin." The results were between 500 million and 600 million years ago. Because of the age of time, the equipment in those ruins has long been completely damaged, but because it is a space environment. So they still sort of keep their own structure. I think, with the resources and means of the human government. It's not necessarily possible to get some technology from these ruins. ”

"500 million to 600 million years ago!" Zhao Lan was shocked by this number again. Hundreds of millions of years...... What a distant time these are. At that time, there were probably only the most primitive multicellular organisms on the earth, but at that time, an unknown alien civilization came to the solar system, and they left some ruins in the solar system and then drifted away, not knowing where they came from or where they were going.

Li Yunfan continued: "When I discovered this black hole, it only had a mass of more than two million tons left, so I was able to slim down for it and then have a chance to bring it back to Earth. According to the calculation of this point in time and the remaining mass, when the site was still in operation, its mass was about 340 million to 360 million tons, which still belongs to the category of miniature black holes, so it is still very likely that it was artificially created. ”

Zhao Lan's thoughts had almost fallen into a blank at the moment, and he didn't know what to say. The words Li Yunfan said were so amazing that Zhao Lan couldn't digest them in a short period of time.

If it is true that 5 to 600 million years ago, there was a civilization in the solar system that was 300 years more advanced than the current human civilization...... Do they still exist? Is it lost in the vast universe, or does it still exist? If so, why? If they still exist, what will their technology reach after such a long period of development?

Compared to the entire universe, no, just compared to the age of the solar system, the history of human civilization is really too short, and human civilization is too young. The recorded history of mankind is only 5,000 years at most, but what about the history of the solar system? Forty-five billion years. How many orders of magnitude is the difference between this?

Li Yunfan continued to say quietly: "I don't know much more about this alien civilization relic than you. I can also say that I know nothing other than knowing its history and location. So you don't have to ask me anything more, because I don't know. ”

Zhao Lan knew that he shouldn't think about these things for too long, but these things were like magic, which always made Zhao Lan fall into deep thinking unconsciously. Zhao Lan wanted to know the ins and outs of all these things, wanted to know everything about this civilization, and wanted to know what cosmic mysteries they had mastered...... But these things can't come to fruition after all.

Zhao Lan breathed rapidly, and it took a long time to shake out the questions in his mind.

Li Yunfan looked at Zhao Lan gently, and said softly: "Don't think about those questions anymore, okay?" Compared to these ethereal things, I think. Cherishing our limited life is the most important thing. ”

"One last question for me." Zhao Lan said with a struggle: "Why did you bring this black hole back to Earth in the first place? Don't you know how dangerous this is for the planet? ”

Li Yunfan's expression was full of helplessness: "This matter is indeed what I did wrong...... At that time, my self-confidence was too inflated. I don't think this black hole can happen in my hands. Second, at that time, I wanted to use this black hole as a bargaining chip to blackmail the human government into submitting to me when necessary...... In fact, in the end, vanity is at work. You think, I have a black hole in my hand, and I can destroy the whole earth at any time if I want to, this is a matter of Dora Feng. Now, of course, I don't have that kind of thought. Fortunately, the black hole did not make any trouble on Earth. ”

Zhao Lan couldn't help but roll her eyes, and couldn't help but sketch in her mind the image of an arrogant young man who was "the biggest in heaven and on earth".

"It's time for this to be over." Zhao Lan thought like this, "The Disaster of the Stars is over, Li Yunfan is back, and most of my questions have been answered, and those questions remain...... I'm afraid I won't be able to find the answers in my life, so don't waste any more energy thinking about them, and leave these unsolved mysteries to the future descendants of mankind to solve. ”

Three months later.

The head of state fulfilled his promise as promised, and while personally attending the wedding of Li Yunfan and Zhao Lan, he also brought a large number of media reporters. What made Zhao Lan feel a little funny was that. The head of state actually arranged for Li Yunfan to be a "thawing person", claiming that Li Yunfan was frozen hundreds of years ago. And then the first person to "travel through history" on the human history of the current thaw and resurrection, and fictionalized a very moving love story between the thaw and the modern beautiful scientist, which was hyped up with the help of various media, so the people were successfully aroused, and a large number of media reporters naturally flocked to it.

When Li Yunfan and Zhao Lan stood side by side to welcome the guests, the head of state was the first to come over and shake hands with Li Yunfan. Zhao Lan heard it very clearly, and when he shook hands with the head of state, Li Yunfan gritted his teeth and said a sentence: "You are the thawing person, and your whole family is the thawing person!" ”

The Führer still smiled, but his words were not so pleasant: "You have been playing with me for so long, this time, I will play you instead." ”

The conversation between the two lasted only a moment, and after just two sentences, the two shook hands and smiled together to face the media reporters who took pictures, so this scene was recorded forever, and made major media headlines the next day, with the headline "The head of state personally attended the wedding of Zhao Lan, the first thawing man and beautiful scientist in history, and shook hands with the thaw." ”

The galaxy-class spaceship promised by the head of state was also successfully delivered to Li Yunfan and Zhao Lan after being modified. The ship originally required at least a hundred people to operate, but after being modified, only one person was needed to operate. Of course, many of its original features are also unusable. But those functions were all developed for the sake of fighting, and Li Yunfan and Zhao Lan couldn't use those functions.

After getting their hands on the spaceship, the two quickly decided to go on an expedition to Pluto as their honeymoon. But in the Earth Harbor, Zhao Lan was reluctant to board the spaceship, but seemed to be waiting for someone there.

Li Yunfan kept urging, but Zhao Lan always refused to set off. It wasn't until the three people carrying large bags and small bags in the distance ran over panting that a smile appeared on Zhao Lan's face.

When he got closer, Li Yunfan saw clearly that the three people were An Liya, Cruise, and Zhou Xiaoming.

Li Yunfan's face quickly fell, and he yelled angrily: "Hey! Tyrannosaurus, bald, keyboard! What are you three here to do! This is my honeymoon trip with Zhao Lan, what are you here to have fun! ”

Zhou Xiaoming said with a smile: "Boss, this galaxy-level spaceship is so big and has so many rooms, don't worry, the three of us will definitely hide in the corner, and we will definitely not disturb the good things of you and Zhao Lan." ”

An Liya glanced at Zhou Xiaoming and shouted: "What are you talking nonsense, it's obvious that we are reluctant to be separated from the boss for so long, so we have worked hard and given up our own affairs to go to Pluto with the boss for an expedition, okay?" ”

Cruise also smiled and said: "That's it, boss, you said that no matter when we come to see you, you and Zhao Lan will welcome us, but now boss, you won't regret it, right?" ”

Li Yunfan's face was full of helplessness: "It turns out that you have planned it a long time ago...... Okay, okay, don't talk nonsense, hurry up and get on the boat, we're about to go. ”

An Liya and the three cheered together, and Zhao Lan also showed a smile on her face: "Don't forget, I'm also a member of the adventurer team, and now our adventurer team has finally been put together." So...... What are we waiting for? Let's go on an adventure with our squad of adventurers! ”

"Let's go, let's go!" (To be continued......)
