There was a theory known as the "Red Queen" in Western biology.
This theory meant that in the evolution of the biological world, all creatures had to constantly compete with other species around them. Once the evolution stopped, the species would be ruthlessly eliminated.
The entire process of evolution could be described as "a boat sailing against the current. If you don't advance, you'll be pushed back". Foreigners did not know this saying, but in the story of Alice in Wonderland, the Red Queen said to Alice, "In this world, you must keep running to keep yourself in place."
Therefore, scientists named this the Red Queen theory.
When it came to evolution, viruses had to be mentioned.
In the 1990s, biological sequencing technology was relatively mature. Scientists began to study the nucleotide sequence in human chromosomes to decipher the secrets of the human genetic code.
Researchers found that about 8% of the structure of the human genome was confirmed to be composed of viruses that had attacked our ancestors. Another 40% to 50% of the structure was suspected to be composed of viruses that had attacked our ancestors.
Simply put, viruses were like robots mainly composed of nucleic acids. When attacking humans, they would embed themselves into the nucleotide chain of human cells like a parasite, then secretly dismantle the nucleic acid of the cells and make it identical to themselves to make a large number of copies of themselves.
However, during replication, it was very easy to leave a part of itself on the human DNA chain. For example, the production of the placenta was the result of a virus infection. This virus could synthesize syncytial hormone, and the phenomenon of viviparous birth appeared in mammals after being infected with this virus.
These viruses were known as "endogenous retroviruses". Some of them were even the most important enemies in human history, but they had become an indispensable part of human evolution until now.
Therefore, it was a very common thing to evolve humans through a virus.
At this time, Chen Chen was analyzing the BE-006 virus while referring to the information of the Progenitor virus that had been deciphered in the Hive.
Through the various high-end equipment in the Hive laboratory and the intelligence of X-112, the various uses of the BE-006 gene were detected little by little at a speed that was almost incomprehensible in the real world.
There were 1467 genes in the genetic sequence of the BE-006 and 50 genetic codes. Although the interpretation was extremely fast with the computing power of X-112 and the machines in the laboratory, it still took several days.
Therefore, Chen Chen simply stationed the remaining Black Knight in front of the passage to guard the way back while Chen Chen followed the tracks to the surface to take a look.
The corridor that the tram traveled on was not very far, only about five kilometers. Chen Chen reached the end in less than an hour.
At the end of the corridor was a tram covered in scratches and a sealed door.
"X-112, open the door."
Chen Chen used the radio communication device to speak to X-112 who was now in control of the Hive. Suddenly, the door slowly rose.
Chen Chen still remembered that at the end of the first movie, Alice and Matthew escaped on the tram and were attacked by the Lickers on their way out.
In the end, the two of them killed the Licker and closed the Hornet Nest's door. However, as soon as they escaped the tiger's mouth, they were once again captured by the members of the Umbrella Protection Unit. The Umbrella Protection Unit opened the door again, allowing the zombies to spread to Raccoon City.
As the door was completely opened, a ray of light pierced through the originally dark tunnel and shone in.
Chen Chen narrowed his eyes and reached out to block the light. Only then did he realize that the building outside the door seemed to have collapsed.
After letting his eyes slowly adapt to the light, Chen Chen walked out of the door. Suddenly, the ruins of a villa that was about to collapse appeared in front of him. Chen Chen appeared in the ruins.
This was the place where Resident Evil began: the mansion villa.
The endless weeds were almost half the height of a person. A large number of creepers wrapped the entire ruins, turning it into a green wasteland.
Chen Chen searched around casually, but other than a few corpses that had long decomposed beyond recognition, there was only endless greenery.
Chen Chen walked out of the ruins and immediately saw ruins in the distance. That was Raccoon City, a small city that had been hit by a nuclear power equivalent of 5,000 tons.
Strictly speaking, 5,000 tons was not a large amount. Now, it seemed that after this nuclear bomb exploded in mid-air, it flattened the buildings within a radius of five square kilometers. In addition, it left a circular crater about one kilometer in diameter in the center of Raccoon City.
However, fortunately, the yield was not large, so the Hive, which was located 300 meters below the city center, withstood this attack and was not affected much.
Other than that, Chen Chen did not see any zombies, nor did he see any traces of humans.
After walking around Raccoon City, Chen Chen did not find anything of value. Of course, the explosion destroyed Raccoon City and almost all the zombies here.
Some zombies that were lucky enough to survive could only dissipate on their own because there was no energy and water to replenish them.
Chen Chen walked into a relatively intact house in the suburbs, only to see countless vines spreading in wantonly. Even the interior of the room was covered with plants. In addition, there were several corpses that had long since decomposed on the ground.
These corpses had become skeletons, and it was not possible to tell whether they were humans or zombies when they were alive.
After walking around a little, seeing that it was almost night, Chen Chen returned to the Hive out of caution. He asked X-112 to close the door again and seal the place.
If he wanted to explore this world, there would be plenty of time in the future, but now was not the time.
Chen Chen still had an important mission this time.
In the next two days, Chen Chen did not go out anymore. Instead, he looked up all the biological information in the Hive, which gave Chen Chen great inspiration.
Until two days later, when Chen Chen was about to finish eating the food he brought, the analysis of the BE-006 virus gene was finally completed.
After analyzing the role of each base pair of BE-006, the next step could not be simpler. He just needed to use the adenine base editor to edit the corresponding gene of the BE-006 virus, transforming BE-006 into a non-contagious and non-toxic virus.
This was a new virus obtained through gene editing engineering. It was not much different from the original BE-006 and was also a kind of vaccine.
After this new virus was implanted into the human body, because it was not toxic, the human body had enough time to produce antibodies. As long as the antibodies could be produced, the human body would naturally be immune to BE-006.
This method was achieved by understanding the BE-006 gene. In addition to being able to analyze all the genes of the virus, the difficulty was to have the ability to accurately edit the genes.
Only when both requirements were met could the virus Chen Chen needed be edited.
It was very difficult to achieve this level of biotechnology in reality, even more difficult than the production of viral protein vaccines. Only the Resident Evil dimension could easily achieve this level.
Chen Chen had come to the right place.
