In Western biology, there is a theory of the "Red Queen".

The meaning of this theory is that in the evolution of the biological world, all living things must constantly compete with other species around them, and once evolution is stopped, then this species will be eliminated without mercy.

The whole evolutionary process can be described by the phrase "if you don't advance against the current, you will retreat", and the crooked nuts don'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." ”

So, scientists named this the Red Queen Theory.

And at the evolutionary level, we have to mention viruses.

In the 90s of the last century, biological sequencing technology has been relatively mature, and scientists began to study the nucleotide sequences in human chromosomes to decipher the secrets in the human genetic code.

Researchers have found that about 8% of the structures in the human genome are confirmed to be made up of viruses that once attacked our ancestors, and 40%-50% of the structures are suspected to be made up of viruses that invaded our ancestors.

To put it simply, a virus is like a robot composed mainly of nucleic acids, and when attacking humans, it will embed itself into the nucleotide chain of human cells like a parasite, and then secretly disassemble the nucleic acids of the cells to make the same appearance as itself, so as to replicate a large number of itself.

However, when replicating, it is easy to leave a part of itself in the human DNA chain, such as the production of the placenta, which is the result of a viral infection, which can synthesize syncytin, and mammals are infected with this virus before it becomes viviparous.

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 analyzed the BE-006 virus while comparing the data of the progenitor virus cracked in the hive.

Through the state-of-the-art equipment in the Hive Laboratory, as well as the intelligence of X-112, BE-006's genes are being detected for various uses at a rate that is incomprehensible to the real world.

BE-006 has 1,467 genes in its genetic sequence, encoding 50 genes, which can take several days to interpret with the computing power of X-112 and machines in the lab.

So, Chen Chen simply let the remaining black knight stand in front of the passage and guard the back road, while Chen Chen followed the railroad tracks and prepared to go to the ground to have a look.

The tram was not far away, only about five kilometers, and Chen Chen came to the end in less than an hour.

At the end is a scratched tram and a sealed gate.

"X-112, open the door for me."

Chen Chen used his radio communication equipment to say a word to X-112, which was now in control of the hive, and suddenly, the gate slowly rose.

Chen Chen still remembers that at the end of the first part of the movie, Alice and Matthew escaped by tram, and were attacked by lickers on the way to escape.

However, in the end, the two of them still killed the licker and closed the door to the hive at the same time, only to be caught by the Umbrella personnel again, and the Umbrella opened the door again, allowing the zombies to spread to Raccoon City.

As the gate opened completely, the originally dark passage was finally pierced by a ray of light.

Chen Chen narrowed his eyes and stretched out his hand to block the light, only to find that the building outside the gate seemed to have collapsed.

After letting his eyes slowly adjust to the light, Chen Chen walked out of the door, and suddenly, the ruins of a villa that was about to collapse appeared in front of him, and Chen Chen appeared in the ruins.

This is where Resident Evil begins: the Western-style villa.

Endless weeds are almost half a man's height, and a large number of creeper plants envelop the entire ruins, turning the place into a green wasteland.

Chen Chen searched here casually, but except for a few corpses that had long been decomposed and could not be seen, other than that, there was an endless amount of green.

Chen Chen walked out of the ruins and immediately saw the ruins in the distance, and there was Raccoon City, a small city hit by 5,000 tons of equivalent nuclear power.

5,000 tons is not technically large, but the bomb exploded in mid-air, flattening buildings within a radius of five square kilometers, and leaving a circular crater about a kilometer in diameter in the center of Raccoon City.

However, fortunately, the yield was not large, so the hive, located three hundred meters deep in the center of the city, withstood the attack and was not affected too much.

Other than that, Chen Chen didn't see any zombies, nor did he see any traces.

Walking around the vicinity of Raccoon City, Chen Chen didn't find anything of value, and it was obvious that of course the explosion destroyed Raccoon City, and also destroyed almost all the zombies here.

And some zombies who survived by luck could only dissolve on their own because there was no energy and water supplement.

Chen Chen walked into a fairly intact house in the suburbs, only to see countless vines and plants spreading in wantonly, and even the interior of the room was crawling with plants, in addition to the several corpses that had long since decomposed on the ground.

The corpses were all skeletons, and it was impossible to tell whether they were human or zombies when they were alive.

After a slight turn, seeing that it was almost night, Chen Chen returned to the hive out of caution and asked X-112 to close the door again, sealing the place.

If you want to explore this world, there will be time in the future, but not now.

Chen Chen also has his own important task this time.

In the next two days, Chen Chen no longer went out, but consulted all the biological materials in the hive, which gave Chen Chen a lot of inspiration.

It wasn't 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 the adenine base editor, editing the corresponding genes of the BE-006 virus, and transforming BE-006 into a virus that is not infectious and non-virulent.

This is a new virus obtained through gene-editing engineering, which is not much different from the original BE-006, and is also a vaccine.

After the new virus is implanted into the human body, because it is not toxic, the human body has enough time to produce antibodies, and as long as the antibodies can be produced, then the human body can naturally be immune to BE-006.

This method is achieved through the knowledge of the BE-006 gene, and the difficulty is not only to be able to resolve all the genes of the virus, but also to have the ability to accurately edit the genes.

Only if both of them meet the requirements can the virus that Chen Chen needs be edited.

It is very difficult for real-world biotechnology to achieve this level, even more difficult than the manufacture of viral protein vaccines, which can only be easily achieved by the Resident Evil Plane.

Chen Chen came to the right place.
