Chapter 419 The Tragedy of Engineer Civilization
That's right, after confirming that it was this terrible planet, Liu Xiu planned to have the unmanned exploration spacecraft self-destruct after taking the true image of the planet, and no longer recover these exploration spacecraft.

Liu Xiu had watched all the movies about this planet and the Alien series in his previous life, and he was especially familiar with the stories of the Engineer civilization.

According to the movie story background that Liu Xiu found on the Internet in his previous life, the intelligent creatures in this engineer civilization are a very long-lived race.

According to David, the cyborg in the movie, their lifespan can reach at least 30,000 solar years. However, after the Engineer civilization developed to a certain stage, it encountered a reproduction crisis. No matter how long the life is, it will not be able to withstand aging day by day. Therefore, in order to continue civilization, the creatures in the Engineer civilization want to find alternative ways to reproduce.

The specific cause of this situation is still unknown. According to online speculation in Liu Xiu's previous life, it may be related to the genetic modification experiments within the Engineer civilization, or the environment. Because of the sudden changes in the environment of this planet, problems have arisen in the reproduction of the Engineer civilization.

Of course, the greater probability is that it is related to genetic modification. Because we don’t know much about genes, and in order to achieve longevity, we made major changes to the genes. Then we found that although the modified genes made us live longer, we lost the ability to reproduce.

So when I wanted to transform it back, I found that I was powerless.

During this time, space explorers among the "Engineers" encountered a parasitic virus or life form called Deacon on a certain planet.

The reason for this speculation is that when the Prometheus crew first entered the pyramid building, David used his knowledge of the engineers' language to open the door to the room where the black water was stored. If you look closely, you can see that there are many inscriptions on the door. In the script, David translated the content of the text to the other team members.

"Our Lord was born from the body of the Chosen One. His sacred blood is our salvation and will sow new life in other worlds through our bodies."

From this passage, it can be seen that the Engineers' initial encounter with the Deacon may have been a coincidence, the result of an unknown creature at the time parasitizing their bodies. Later, further research on the Deacon found that its blood could decompose organisms and reorganize them at the genetic level.

The engineers who were originally desperate saw the hope of the continuation of their race, and they extracted the blood of the "deacon", and this blood was called black water, which was the thing that the alien drank at the beginning of the movie.

So the engineers used it to spread the seeds of civilization in the universe. And the creature "Deacon" had a lofty status in the engineer group, and they worshiped it as a god who blessed the continuation of the race.

Therefore, the Engineer civilization, which had trouble reproducing, relied on "Deacon Blood", or black water, to spread civilization throughout the universe. Unfortunately, most of them failed. Only the one on the Blue Planet produced results, and humans were born there.

However, in Liu Xiu's opinion, perhaps not only one Blue Star was successful, but most of the life planets similar to Blue Star that are suitable for human survival seem to have succeeded. And because they all inherited the engineer civilization, his home planet is called Blue Star.

Therefore, the Engineers were very attentive to this ignorant race at first. They often visited Earth and taught humans to use more advanced technology. However, the moral standards of humans did not rise synchronously with the evolution of civilization. The Engineers found that they were a violent race, which might be related to the mixed genes of aliens. It would be very dangerous to allow their civilization to continue to develop. Therefore, on the issue of how to deal with humans, the Engineers were divided into two factions. One faction advocated that humans should be saved, and the other advocated that humans should be completely wiped out.

This is like when a naughty child makes a mistake, the mother hopes not to punish him but to teach him with love, while the father believes that a good child is born under the stick. For this reason, the redemption faction among the engineers even went to the blue planet to choose a baby boy and took him to live on the paradise planet, which is the mother planet where the engineer civilization was first born, hoping that he would lead mankind to a path of peace after returning. Unexpectedly, after being sent back to the blue planet, humans nailed him to the cross.

This completely disappointed the Redemptionists, and the Destructionists among the engineers gained the upper hand. They decided to use black water to wipe out all humans and restart the ecology of the Blue Planet.

However, just after the mass production of this terrible parasite, Black Water, before it could be used, the researchers in the Engineer civilization discovered that the violent tendencies in humans were likely derived from the Deacon's genes, and that species created with Black Water might have the same result, so the substance was temporarily sealed on LV-223 until they could find a way to solve this problem.

However, the Destructionists in the Engineer Civilization still decided to use the black water to eliminate humans. In fact, after another ecological restart, the new race born would be improved. So several engineers from the Destructionists came to LV-223 to open the spacecraft sealed there. However, when they were checking the cargo hold, an accident occurred. Several creatures infected by black and turned into aliens appeared and attacked them. In the end, only one of these engineers survived and hid in the hibernation cabin waiting for rescue from his compatriots. Unexpectedly, two thousand years later, they were waiting for the humans they originally planned to eliminate.

So the result is naturally clear. The engineers of the Destruction Faction have always looked down on the humans on Blue Star, and then David's creator Wei Lun came to the engineer and expressed his desire to obtain eternal life.

So the opposing engineers, who were already trapped by eternal life, naturally became immediately annoyed, and without saying a word, they twisted off the head of David, the bionic man, and kicked Wei Lun to death.

What is more crucial is that this destructive engineer still plans to continue driving the spaceship to complete his previous plan, which is to bring the black water to the Blue Planet and then destroy the Blue Planet.

So the scene in the movie appeared. In order to save his hometown Blue Planet, the captain of the spaceship resolutely drove the spaceship to crash down the engineer's spaceship.

Of course, all of this was clearly observed by Liu Xiu using the enemy and friend map, but it was a pity that only Liu Xiu could see all of this because the distance was one thousand astronomical units, or 150 billion kilometers.

Therefore, even an unmanned exploration spacecraft would have to fly for nearly a month to reach the planet LV-223.

There is no way to let the unmanned exploration spacecraft be equipped with a curvature engine! So the distance of one thousand astronomical units can only be hard-flying.

The main reason for not equipping the unmanned exploration spacecraft with a curvature engine was that when the civilization of Blue Planet No. 2 was preparing to attack it, it did not have the curvature engine technology. Therefore, for fear of learning it, it was not installed.

Therefore, the unmanned spacecraft that is exploring the planet LV-223 this time is naturally equipped with this kind of thing.

After all, it would be inappropriate if something that is equivalent to a disposable consumable is too advanced or too expensive.
