When the word "unknown civilization ruins" was proposed by Li Yunfan, Zhao Lan covered her mouth in surprise, her face full of shock: "Unknown civilization ruins?"

"Yes." Li Yunfan nodded gently, his face full of sighs: "It is the ruins left by an unknown civilization there. Our human civilization has been struggling with whether it is the only one in the universe and has been committed to finding alien civilizations. But who would have thought that there is a ruins of alien civilizations in our solar system."

"How is this possible? You mean, because there is a ruin of an alien civilization in the Jupiter system. In order to keep this secret and to prevent the possible dangers of this ruin, the human government chose to conceal the incident of landing on the Jupiter system?"

"It's probably that." Li Yunfan spread his hands: "Of course, the government cannot stop me. I came to the Jupiter system with the power I accumulated myself. According to the place where the teacher said, I found a second ruin in the orbit around Jupiter, and found the black hole in that ruin, and then brought it back to Earth. I can be sure that the government must now search the Jupiter system, and only after confirming that all possible ruins are in their hands will the Jupiter exploration plan be approved."

"The ruins I found are not the same as those controlled by the human government, but they are basically 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 take about three hundred years to catch up with the technological level of that civilization."

Three hundred years is very short compared to a whole civilization, and it is even so short that it is a bit inconspicuous. According to the gap of three hundred years, it seems that the technological gap between the earth civilization and the unknown civilization is not big. But Zhao Lan knows that the truth is not the case. Just like from now on, it was probably the era of Zhao Huasheng. In that era, human civilization has devoted all its strength to the whole civilization to build a small base on the moon. What about the current human civilization? It can even build a big city on Mars. This is just the most obvious progress. The rest of the places, space elevators, Earth and Mars ports, super-large-scale rapid underground transportation networks, flight instruments, aerospace carriers, etc., are simply one in the sky and one underground compared to three hundred years ago.

Moreover, the technological development speed of human civilization has been accelerating. So what would it look like if human civilization develops for another three hundred years? Zhao Lan couldn't imagine it. But now Li Yunfan said that the technological level of unknown alien civilization that left behind the unknown remains is probably three hundred years ahead of the earth civilization.

It is completely understandable that civilizations that are three hundred years ahead of the Earth civilization create artificial black holes.

But there is a very important question among them, that is, how long is the history of this ruin? If the ruin has been 10,000 years or even 100 million years, then how terrible is the current technological level of that civilization?

Li Yunfan seemed to see the doubt in Zhao Lan's eyes, so he replied: "I have measured the history of the ruins. The result was between 500 million and 600 million years ago. Because of the long time, the equipment in the ruins had been completely damaged, but because it was a space environment, they probably maintained their own structure. I think it is not certain that they can obtain some technology from these ruins with the resources and means of the human government."

"Five hundred million to six hundred million years ago!" Zhao Lan was shocked by this number again. Hundreds of millions of years... What a distant time. 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. They left some remains in the solar system and then floated away, not knowing where they came from or where they were going.

Li Yunfan continued: "When I discovered this black hole, its mass was only more than 2 million tons, so I could lose weight for it and then have the opportunity to bring it back to Earth. Based on this time point and the remaining mass calculation, when the site was still operating, its mass was about 3.40 million tons to 3.66 million tons, and it still belongs to the category of micro black holes, so it is still very likely that it was artificially manufactured."

Zhao Lan's thoughts were almost blank at this moment, and she didn't know what to say. The words Li Yunfan said were too amazing, and Zhao Lan could not digest them in a short period of time.

If there was really a civilization in the solar system that was three hundred years ahead of the current human civilization... do they still exist now? Did they disappear in this vast universe or still exist? If it has disappeared, why did it disappear? If it still exists, then after such a long period of development, what will their technology reach?

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 history of human beings with written records is only 5,000 years at most, but what about the history of the solar system? It is 4.5 billion years. How much is the order of magnitude difference between these?

Li Yunfan continued to say quietly: "I don't know much more about this alien civilization ruin than you. Apart from knowing its history and location, I can also say I don't know anything. So you don't need to ask me more, because I don't know either."

Zhao Lan knew that she shouldn't think about these things for too long, but these things were like magic, which always made Zhao Lan fall into deep thoughts without realizing them. 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 the secrets of the universe they had mastered... But these things could not have a result after all.

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

Li Yunfan looked at Zhao Lan gently and said softly: "Don't think about those problems anymore, okay? Compared with these illusory things, I think it is the most important thing to cherish our limited lives."

"Answer my last question." Zhao Lan said with a struggle: "Why did you bring this black hole back to Earth? Don't you know how dangerous this is to Earth?"

Li Yunfan's expression was full of helplessness: "I did this wrong... At that time, my confidence was too inflated. I thought that this black hole would not have an accident in my hands. Second, at that time, I thought that when necessary, I would use this black hole as a bargaining chip to threaten the human government to surrender to me... In fact, vanity is still at the end of the day. You think, if you have a black hole in your hand, I can destroy the entire earth at any time as long as I want. Of course, now, I no longer have this idea. Fortunately, there is no chaos in the black hole on the earth."

Zhao Lan couldn't help but roll her eyes, and couldn't help but outline the image of an arrogant young man who was "I am the biggest in the sky and the earth".

"This matter should end now." Zhao Lan thought, "The disaster of stars is over, Li Yunfan is back, and most of my questions have been answered, and the remaining questions... I am afraid I will not find the answer in my life, so don't waste my energy thinking about them anymore. Just leave these unsolved mysteries to the descendants of future human beings to answer."

Three months later.

The head of state fulfilled his promise as promised. While coming to attend the wedding of Li Yunfan and Zhao Lan in person, 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 as a "thawing man", claiming that Li Yunfan was frozen hundreds of years ago. Then, in the current thawing and resurrected human history, he fictionalized a very touching love story between the thawing man and modern beautiful scientists, and promoted it with the help of various media, so the people were successfully attracted to their interest, and a large number of media reporters naturally flocked to them.

When Li Yunfan and Zhao Lan stood side by side to welcome the guests, the Head of State was the first person to come over to shake hands with Li Yunfan. Zhao Lan heard very clearly that when she shook hands with the Head of State, Li Yunfan gritted her teeth and said: "You are the thawing person, your whole family is the thawing person!"

The head of state still kept smiling, but his words were not so pleasant: "You have been fooling me for so long. This time, I will be fooling you."

The conversation between the two lasted for only a moment. After just two sentences, they shook hands and smiled together to face the media reporters taking photos. So this scene was permanently recorded and made headlines of major media the next day. The title was "The Head of State personally attended the wedding of the first thawing man and the beautiful scientist Zhao Lan in history, and shook hands cordially with the thawing man."

The Galaxy-class spacecraft agreed by the head of state was successfully delivered to Li Yunfan and Zhao Lan after being modified. The spacecraft originally required at least one hundred people to operate, but after modification, it only needed one person to operate. Of course, many of its original functions could not be used. However, those functions were developed for combat, and Li Yunfan and Zhao Lan could not use those functions.

After getting the spaceship, the two quickly decided to take a Pluto adventure as a honeymoon trip. However, in the Earth Harbor, Zhao Lan refused to board the spaceship for a long time, but seemed to be waiting for someone there.

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

It was not until they got closer that Li Yunfan saw clearly that the three people were An Liya, Cruise, and Zhou Xiaoming.

Li Yunfan's face quickly collapsed and he shouted in anger: "Hey! Tyrannosaurus, bald, keyboard! What are you three here to do! This is my honeymoon trip with Zhao Lan, why are you here to join in the fun!"
