There is a "Red Queen" theory in Western biology.
The meaning of this theory is that in the evolution of the biological world, all organisms must constantly compete with other species around them. Once evolution stops, this species will be eliminated mercilessly.
The entire evolutionary process can be described by the saying "If you don't advance, you will retreat." Waiguoren doesn't know this sentence, but in the story of "Alice in Wonderland", the Red Queen said this to Alice: "In this world, you have to keep running to keep yourself in place."
Therefore, scientists named this the Red Queen Theory.
When it comes to the evolutionary level, we have to mention viruses.
In the 1990s, biological sequencing technology became relatively mature, and scientists began to study the nucleotide sequences in human chromosomes to decipher the secrets of the human genetic code.
Researchers found that about 8% of the structures in the human genome are confirmed to be composed of viruses that once invaded our ancestors, and 40%-50% of the structures are suspected to be composed of viruses that invaded our ancestors.
To put it simply, a virus is like a robot mainly composed of nucleic acid. When attacking humans, it will embed itself into the nucleotide chain of human cells like a parasite, and then secretly remove the nucleic acid of the cell to make Make a lot of copies of yourself with the same appearance as yourself.
However, when replicating, it can easily leave part of itself on the human DNA chain. For example, the production of placenta is the result of a viral infection. This virus can synthesize syncytin. When mammals are infected with this The phenomenon of viviparous birth appeared only after the virus.
These viruses are called "endogenous retroviruses", and some of them are even the most important enemies in human history, but they have become an indispensable part of human evolution to this day.
Therefore, it is normal for humans to evolve through a virus.
At this time, Chen Chen was analyzing the BE-006 virus while comparing it with the information on the ancestor virus cracked in the hive.
Through various high-end equipment in the Hive Laboratory, as well as the intelligence of X-112, BE-006's genes were detected bit by bit for various uses at a speed that is almost incomprehensible in the real world.
BE-006's genetic sequence contains 1,467 genes and 50 gene codes. Although the interpretation is extremely fast with the computing power of X-112 combined with the machines in the laboratory, it still takes several days.
Therefore, Chen Chen simply asked the remaining black knight to station in front of the passage and guard the back road, while Chen Chen followed the railway track to take a look at the ground.
The passage the tram travels through is not far away, only about five kilometers, and Chen Chen reached the end in less than an hour.
At the end is a tram covered in scratches and a sealed gate.
"X-112, open the door for me."
Chen Chen used the radio communication equipment to say something to X-112, who was now in control of the hive. Suddenly, the gate 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 Lickers on the way.
However, in the end, the two of them killed the Licker and closed the door of the hive. Just as they escaped from the tiger's mouth, they were caught again by the Umbrella personnel, and the Umbrella opened the door again, allowing zombies to spread to Raccoon City.
As the door was completely opened, the originally dark passage was finally penetrated by a ray of light, shining in.
Chen Chen squinted his eyes and stretched out his hand to block the light. Only then did he realize that the building outside the gate 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 among the ruins.
Here is where the biohazard begins: the mansion villa.
Endless weeds are almost half as tall as a man, and a large number of creeper plants surround the entire ruins, turning it into a green wasteland.
Chen Chen casually searched here, but except for a few corpses that had long since rotted beyond recognition, there was endless green as far as the eye could see.
Chen Chen walked out of the ruins and immediately saw the ruins in the distance. There was Raccoon City, a small city that had been hit by five thousand tons of nuclear power.
Strictly speaking, the yield of five thousand tons is not large. Looking at it now, after the nuclear bomb exploded in mid-air, it flattened the buildings within a radius of five square kilometers. In addition, it left behind in the center of Raccoon City. A circular crater about one kilometer in diameter.
Fortunately, the impact was not large, so the hive located three hundred meters deep in the city center withstood the attack without being greatly affected.
Apart from this, Chen Chen did not see any zombies or any human traces.
After walking around Raccoon City, Chen Chen didn't find anything of value. It was obvious that the explosion destroyed Raccoon City and almost all the zombies here.
Some of the zombies who were lucky enough to survive had no choice but to decompose themselves because they had no energy and water to replenish.
Chen Chen walked into a relatively intact house in the suburbs. He only saw countless vines spreading indiscriminately. Even the inside of the room was covered with plants. In addition, there were several long-decomposed corpses lying on the ground. .
These corpses have become skeletons, and it is impossible to tell whether they were humans or zombies during their lifetime.
After a slight turn, seeing that it was almost nightfall, Chen Chen returned to the hive out of caution and asked X-112 to close the door again and seal the place.
If you want to explore this world, you will have plenty of time in the future, but not now.
Chen Chen still has his own important mission this time.
In the next two days, Chen Chen no longer went out, but looked up all the biological information in the hive. This information gave Chen Chen a lot of inspiration.
It was not until two days later, when Chen Chen was about to finish the food he brought, that 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 is as simple as using an adenine base editor to edit the corresponding genes of the BE-006 virus and transform BE-006 into an Viruses that are contagious but not virulent are enough.
This is a new virus obtained through gene editing engineering. It is almost the same as the original BE-006, and it is also a vaccine.
After this new virus is implanted into the human body, because it is non-toxic, the human body has enough time to produce antibodies. As long as antibodies can be produced, the human body will naturally be immune to BE-006.
This method is achieved through the understanding of the BE-006 gene. The difficulty is not only to be able to analyze all the genes of the virus, but also to have the ability to accurately edit the genes.
Only when both of them meet the requirements can the virus Chen Chen needs be edited.
It is very difficult for biotechnology to reach this level in reality, even more difficult than the production of viral protein vaccines. Only the biohazard plane can easily achieve this level.
Chen Chen came to the right place.
