Wei Feng didn't think of this at all.∷, no matter where this alien came from, Wei Feng wouldn't be too surprised. After all, the universe is so big that there are countless incredible things, but... if this alien comes from the solar system and from Mars, it would be a bit difficult to accept.

"But how could it be Mars?" Wei Feng murmured, "The environment on Mars is so harsh, without water, and the atmosphere is so thin..."

Ye Luo said: "Why can't it be Mars? Captain, don't forget that according to our speculation, this alien civilization may have existed for as long as 500 to 600 million years, and what happened 500 million and 600 million years ago... Who can tell clearly?"

Wei Feng remained silent, and Ye Luo continued: "Although we cannot be sure of this, in addition to the four indicators you proposed before pointing to Mars, we also have the most powerful evidence. This evidence is... the technology of this alien civilization is actually not much advanced than ours. In our speculation, with this level of technology, it is really unlikely to launch a large-scale interstellar navigation. We have thought that interstellar navigation may not require too high technology to explain the occurrence of an alien civilization with low technological level in the solar system. But don't you feel that this explanation is too far-fetched? On the contrary, if you think that this alien civilization simply comes from within the solar system, then everything we face is reasonable."

Wei Feng stood up with some difficulty, and once again came to the hibernation cabin, carefully looking at the hibernation cabin. The alien life frozen in the light blue solid. His thoughts were like the sea surface under the strong wind: "Indeed, if they simply came from the inside of the solar system, then all contradictions could be explained very reasonably. Not only that, the war that happened 50 to 600 million years ago can also be explained... Then, in this way, we can make the following speculation: 50 to 600 million years ago, there was a civilization on Mars, and we might as well name it "Martian Civilization."

"The Mars civilization has developed to a level of technology that is slightly more than our human civilization, but I don't know why. There was an extremely huge war inside their civilization. Perhaps it was because of the impact of this war, or because of other reasons, that they eventually became extinct and disappeared from the solar system. Then, after 50 to 600 million years, our human civilization gradually emerged, replacing the Mars civilization and occupying the entire solar system..."

"But there is a fatal contradiction in this inference, Ye Luo." Wei Feng said, "If the Mars civilization had really developed to such a high level of technology five to six hundred million years ago, and even its footsteps had spread throughout the solar system. But why didn't we find any traces of them in the inner solar system? If our human civilization becomes extinct and another civilization appears in 5 to six hundred million years later, they will definitely find the traces of us, because our footsteps have spread throughout the solar system, leaving our creations on almost all satellites and planets. And, since they have had a large-scale war, there must be a large number of wreckage in space, but we have not found these things."

"I don't know." Ye Luo said, "but I have a data model that can try to explain your questions. Look."

While Ye Luo was speaking, a three-dimensional image was directly projected onto Wei Feng's retina. Wei Feng once again saw a reduced version of the solar system, saw the sun, and saw the planet...

A group of densely packed small black dots flew up from different planets and then began to entangle each other in space. During this entanglement, these small black dots shattered into more small black dots, and the small black dots after the shattered obviously lost the ability to act independently.

"I'm simulating the situation of space war." Ye Luo said, "This small black dot represents a warship. The rupture of the small black dot means that the warship is destroyed."

This fierce war lasted for a long time. While these small black dots were entangled in space, planets and satellites in the solar system, or those suspected to be space island bases, were also attacked violently. In the end, there were almost no complete artificial creations in the solar system, and they almost completely turned into ruins.

"Look. After the war is over and many wreckages are left in the solar system, some of the wreckages will have enough momentum, so they will fly out of the solar system and never come back. The other wreckage will be attracted by the gravity of major planets, satellites, and the sun. In the long run, their ultimate fate will be to crash on these stars."

In the simulation picture of Ye Luo projecting on Wei Feng's retina, Wei Feng clearly saw this process. Ye Luo accelerated the passage of time, so Wei Feng saw that some of the black dot wreckage quickly escaped from the solar system, while the other part of the black dot wreckage fell on various stars. In this way, there were much fewer wreckage existing in space.

"But a considerable number of wreckage still have stable orbits," Wei Feng said. "Based on their orbits, they will continue to circulate the sun or other stars stably. The reality is that we have never found wreckage in the solar system at all."

"No, from a long-term time scale, such as a time scale of 50 to 600 million years, their orbits are still unstable." Ye Luo said, "Especially, there is another point, don't forget the influence of the sun. Such a huge war is almost unimaginable without attacking the sun. Then look again."

As Ye Luo spoke, the luminance of the simulated image of the sun suddenly increased several times. Wei Feng knew that this was the situation of Ye Luo after the simulated sun was attacked.

"After the sun is attacked, the solar wind and light pressure will increase many times. Although they cannot affect macroscopic objects in a short period of time, if the time scale is long enough, the impact they can cause cannot be ignored. On the one hand, the influence of the sun, and on the other hand, the gravitational force of major planets pulls them like a naturally formed dust collector. As long as the time is long enough, all the wreckages that exist in the solar system will be removed. They either fall into the star body, or are expelled from the inner solar system and enter the outer solar system space. I think this is why we have not found wreckage in the inner solar system space."

Wei Feng thought for a while and said, "There are still loopholes in this explanation. 1. Why are only the wreckage affected by this? The remaining tiny stars in the solar system were not expelled from the solar system? Don't forget that we have discovered many tiny stars in the solar system. 2. The above explanation only explains the reasons why the wreckage in the universe disappears. So what about the wreckage that fell on various major tiny bodies? Why have we not found wreckage on Mars, Earth, and other tiny bodies?"

Ye Luo immediately replied: "About your first question, I want to ask you, how do you know that 50 to 600 million years ago, there was no large cleaning movement of tiny stars in the solar system due to the influence of the sun? It is very likely that because of the influence of war on the sun, the sun not only cleaned all the wreckage, but also cleaned all the tiny stars. The tiny stars we observe now were just added to the outer solar system later. As for the second question... my answer is still the reason for time. 5.

By 600 million years... this time is too long. Even if the wreckage is above Pluto, it is not affected by the atmosphere or geological movements. In an environment with extremely low temperatures and extremely short light, in such a long time scale, they will gradually lose their own characteristics and eventually become one with the planet itself and can no longer be distinguished. The only thing that can properly preserve them is the environment in the outer solar system. I think this is why we cannot find the remains of Mars civilization... They will all be buried for a long time."

"But...but..." Wei Feng murmured, "Just like we have discovered fossils of ancient creatures, I think there will always be some wreckages that fall on the astral bodies that are just preserved due to various coincidences, right? This possibility must be very great, but why have we not even discovered any signs? This really doesn't explain it."

"I don't know about this question." Ye Luo said, "Maybe we can find the answer one day in the future."

Wei Feng pondered for a while, then shook his head, threw these questions behind his head, and then said: "Although there are still questions in this matter that we have not figured out, we think that this alien civilization came from Mars 500 to 600 million years ago. So Ye Luo, do you think this Martian civilization has survived to this day and finally arrived in the South Gate Two Galaxy, and has some tacit understanding with the human civilization government, and then sends a signal to the human civilization "You can come here" in the South Gate Two Galaxy. How likely is this situation...?"

"I think, before thinking about this issue, we need to understand another problem, that is...what do you think the reason for the huge war between the Martian civilizations?" (To be continued...)

ps: I caught a cold... I was sore all over, my head was dizzy... I felt like I was afraid I couldn't survive this winter...
