In the year 2237 of the Old Earth Era, Prometheus embarked on a voyage with one million of the most elite warriors, astronauts, and scientists from the countries of the Old Earth Era, and their goal was Andromeda, a galaxy that most closely resembled the solar system.

The choice of this galaxy was the result of repeated observations by the best astronomical telescopes of the time in the Old Earth era, and they felt that according to the situation of that galaxy, there was a high probability that there would be a planet suitable for human habitation.

Prometheus flew out of the gravitational range of the solar system for about a year at a normal cruising speed without disrupting the gravitational balance of the solar system itself, and then increased its speed fifty-fold in half a year by a space ejection, and is still approaching the apex of the normal speed of the universe at a tenfold increase every year.

At this rate of growth, they would be able to reach the limit of the normal speed of the universe in a maximum of seven years, and at this rate of flight, it would take them about thirteen years to reach the designated Andromeda Galaxy.

In this process, the spacecraft has always maintained close contact with the Earth, sending out relevant information every month, although this information is a year or two ago according to the time, this connection has never been broken.

At the same time, the colonization of Mars has begun, and the first group of about 30 million people began to colonize Mars, and their mission is to test the adaptation of humans to the Martian environment, and transplant the first genetically cultivated environmental plants to carry out preliminary modifications to Mars.

In this process, nearly 10 million people died from environmental adaptation, unknown diseases and accidents, and the remaining 10 million people initially gained a foothold on Mars, and built five Martian cities, nearly sixty percent of the first batch of environmental plants, more than 3,000 kinds of plants fully adapted to Mars, and began to reproduce, nearly half of the air in the five Martian cities has begun to be obtained through the photosynthesis of these plants, and everything seems to be developing in the best direction.

In this context, the United Nations organization of the Old Earth era began to launch the second phase of the Mars Migration Program, which is crucial to the overall project, because their group of immigrants will be tasked with mining ore in space.

At that time, the resources of the old earth era had reached their limit, and after the completion of the second phase of the Mars immigration plan, there were no resources to promote the third phase of the plan, and the only way to mine various resources from the universe and transport them back to the earth through the second phase of the migration plan was to supplement the resource gap, so as to continue to promote the migration plan and ultimately reduce the burden on the earth.

However, during the implementation of the second phase of the Martian migration plan, a sudden cosmic magnetic storm swept through the solar system, and all communication equipment failed, and when the magnetic storm swept through the solar system, the spacecraft carrying 50 million second-phase immigrants was still flying in space.

Three years later, the impact of cosmic magnetic storms on the solar system completely disappeared, and the Earth began to contact Mars, and after learning about the situation, they all felt hopeless.

The second phase of the Martian migrant spacecraft was completely wiped out in the space magnetic storm, and all the equipment on the spacecraft was destroyed, and none of the immigrants on the spacecraft survived.

The defense of the Martian atmosphere can not be compared with the earth, in the cosmic magnetic storm, all kinds of cosmic rays and radiation fell on Mars, the environmental plants that had already survived died in large numbers, and various equipment in the five Martian cities were also damaged to varying degrees, the most serious of which was a variety of life-sustaining systems.

In the face of the problem of survival, violence inevitably appeared, within the five Martian cities, between the five Martian cities, there began to be war, the war mode from the very beginning of high-tech weapons, to later gunpowder weapons, and then to later cold weapons, until it was able to contact the earth, only one of the five Martian cities can still maintain basic subsistence operations, and the population has been reduced to only more than one million, and this million or so is not one, divided into more than a dozen factions to occupy different areas of this Martian city, barely able to maintain a state that will not perish。

In this terrible state, it is a question whether these more than a million people will be able to live for another ten years, let alone support the planet.

After getting this news, the earth fell into despair, because the successful take-off of the spacecraft of the second phase of immigration is already the limit of the earth's resources, and the current earth's resources, let alone reopening the immigration plan, even a spacecraft carrying more than a hundred people earlier could not do it, not to mention that the cosmic magnetic storm destroyed the earth's communication system, and the political situation and people's livelihood inside the earth have also fallen into chaos, and a world war will break out at any time.

Despite feeling hopeless, the Old Earth government still did not give up the last glimmer of hope, and that glimmer of hope was the Prometheus spaceship flying to the constellation Andromeda.

After restarting to receive cosmic signals, the earth also regained the information from Prometheus, because of the destruction of the cosmic magnetic storm, this information was incomplete, and after reorganizing, it was okay to be able to roughly understand the situation of Prometheus, and did not encounter this wave of cosmic magnetic storms.

In the eyes of the Old Earth government, as long as the Prometheus successfully found the colonized planet of the alien system, then there was still hope for everything, so with this last glimmer of hope, the governments of the Old Earth era maintained fragile stability and balance.

However, one day three years later, the Old Earth government received a new message from the Prometheus, with only one sentence on it: "We are wrong, we are all wrong, there is nothing here, there is nothing!"

Although this sentence has no beginning or end, everyone knows what this message means after seeing it, and it is also clear what this message represents, the stability that governments finally maintained completely collapsed, and the world war known as the Doomsday War broke out on the third day of the information, and on the fourth day, all countries in the world, including those as small as a town, were involved in the war.

Later, the Earth Federal Government specifically investigated the Prometheus incident, and they deduced from various data that according to the flight speed of Prometheus at that time, it should not have reached the target galaxy, and the target galaxy is not as described in the information, but is a very suitable galaxy environment for human habitation as deduced by scientists in the old Earth era, with as many as three colonizable stars and six resource stars.

It is no exaggeration to say that if the Prometheus spacecraft can reach the target galaxy, then with the technology on the Prometheus spacecraft, it is completely possible to replicate one or three new Prometheus ships within three years, bring a large amount of resources back to Earth, and transport more Earth immigrants to relieve the pressure on Earth, and naturally there will be no Doomsday War.

However, not only did the old Earth government receive information of unknown origin, but even the Prometheus spacecraft disappeared from its course.

Even if the Earth Federation later used various means to find it, and even invited an omega-level advanced life form that can capture the cosmic time ray from the cosmic council, and asked him to find the answer from the time ray, it still did not find any clues.

The answer given by the omega-level higher life form was that there was a higher form of life that interfered with the cosmic time rays.

This also made the Earth Federation wonder if the people of the old Earth era were calculated by some omega-level high-level lifeform, but when I thought about it, I felt that I might have thought too much, because if there was really an omega-level high-level lifeform to deal with the earthlings at that time, there was no need to use these means at all, and it would not be difficult to directly destroy the entire solar system.

It is precisely because of all this inexplicable that the Prometheus has become an unsolvable mystery in the history of the old Earth era of the Earth Federation, and the only thing that can be known now is that there is an alien race calculating the earth, but which alien race it is is still a mystery.

There are also scientists who believe that the alien race that calculated the earth may have perished in a certain civilization race, so that the investigation of the Earth Federation could not find clues, because all the clues disappeared with the demise of civilization.

When Leo was a cyborg, he didn't have any interest in these things from the Old Earth Era, he just passively accepted these materials, and now when he told Sylvia about these sorted out historical materials, he also re-experienced the changes in the world of the Old Earth Era.

I don't know if it's because of normal human emotions, Leo can't help but have some indescribable emotions in his heart in the process of retelling this history.

Leo was still like this, and the mood swings in the heart of Sylvia, who had already broken the heights, listened to Leo's story as if it were a mythological epic.

In what Leo was told, there were a large number of words that seemed to be in another language, which she didn't understand at all, but the mere experience of what she understood was enough to shock her.

For example, hitting a spaceship that tens of millions of people can fly in the sky, such as the ability to transform stars, immigrate stars, etc., this is like listening to some kind of myth in her eyes, even if she has seen so many technologies of cosmic civilization, and even seen the Prometheus towering in front of her and being regarded as a city, she still feels unbelievable.

Although the two of them deliberately slowed down, they still arrived at the entrance gate of Lanxi City when Leo finished recounting the end of the Old Earth era.

I saw that this gate should be the material transportation channel of the middle deck of the Prometheus, the transmission deck of the passage has been extended and fallen to the ground, and the later people reinforced it at the bottom of the deck, added some stone pillars, and placed some stone slabs on the deck of the ladder and road surface to facilitate walking.

According to the rules of Lanxi City, every outsider needs to pay a certain amount of gold-like metal to enter the city, although this metal is a rare metal in the Black Forest, but for those who want to enter the city, this payment is nothing, so it is still a lively scene of traffic at the city gate.

At this time, Sylvia had recovered from the emotion of that period of history in the Old Earth Age, and she looked up at the hemispherical spaceship in front of her, which was as huge as a mountain, and couldn't help but ask, "Why is this Prometheus here?"

"That's what I want to know. Leo replied calmly.

Leo looked up at the light coming out of the windows on the outer wall, and then at the light projected from inside the city gate, he was sure that the Prometheus's basic lighting energy would still work normally even after all these years, which also meant that the main control computer in the Prometheus could also be used, and he might be able to get some useful information from it.

It's just that Leo is also puzzled, because according to the information in his memory, the Prometheus comes with its own energy system, even if it is just to maintain the position of the lighting of the entire spaceship, it will definitely not be able to maintain tens of thousands of years, and the auxiliary energy system is the most primitive energy sail, this energy sail can only collect a small part of the cosmic rays and light energy, even if it is not damaged, in the environment of the Black Forest, the energy sail can almost be said to have become a decoration.

So, he wondered what exactly was the device that maintained the entire Prometheus lighting energy.

Although Leo and Sylvia stopped by the passage of the city gate to look up at the city and the flow of people around them, they did not attract the attention of the people around them, because there were not a few people who behaved like the two of them, and it seemed to them that it was doubtful that the first-time visitors to Lanxie City were not shocked by the grandeur of the city.

Leo and Sylvia also paid for the entrance to the city with Kinsa, and the tax collector in charge of the fees, Lanxi, was a little curious about the gold coin, but he didn't ask much about Kinsa, after all, he had received a lot of new currencies in the past, and he had seen even more strange currencies, so he had long been surprised.

After learning that Leo and Sylvia were visiting Lanxi City for the first time, he briefly explained the precautions, and then took out a booklet that recorded these precautions and a simple map of Lanxi City, and handed it to Leo along with a temporary residence permit for a three-day stay.

After entering the city, Leo briefly flipped through the booklet, and found that the map on the booklet was very rudimentary, only marking the locations of the main urban areas and some forbidden areas, and most of the content behind the booklet was some guides.

Sylvia took the booklet from Leo's hand and looked at it, and quickly noticed the problem with the map, saying, "The area of the map on this seems to be much smaller than the actual area of Lanxi City. ”

"It's less than a tenth of the actual area. Leo gave a relatively exact number.

In his memory, there are some drawings of the construction of the Prometheus, equipment drawings, internal structure drawings, etc., which are so detailed that if there are enough manpower, financial resources and materials, Leo believes that he can also use these drawings to rebuild a Prometheus.

It is no exaggeration to say that in terms of the level of knowledge of the Prometheus alone, the locals of Lanxi are probably far from being able to compare with him, and just by looking at the drawings just now, he has found at least thirty routes and methods that can avoid any guards of Lanxi City and safely enter the forbidden area.
