Listen to Zhou Yalan''s explanation.

    Lu Xiping finally knew the corresponding relationship between the corolla virus and the types of zombies.

    It was also the first time he heard about this. When he was an ordinary person, no one told him this at all.

    At present, according to the meat crown virus that has been studied by human beings, according to the genetic method, it can be divided into 22 large families, and each large family can be subdivided into several to more than a dozen sub viruses. However, this research road is still very long. Zhou Yalan didn''t talk deeply, but put a PPT for everyone to have a look.

    Zhou Yalan focuses on the classification of zombies, which can be divided into three types, namely sea, land and air.

    First of all, carnivorous coronavirus parasitic on terrestrial organisms is called terrestrial virus. The main transmission and parasitic objects of this kind of virus are generally terrestrial organisms, except a few amphibians.

    Among the terrestrial viruses, the most representative is type 7 Sarcocystis virus A. Type 7 refers to the complete algebra of virus evolution, and a is one of viruses. The infection rate of type 7a virus is very fast, and it will quickly zombie in only about an hour. This is also the earliest zombie corolla virus evolved on blue star. Later, these viruses transferred to animals and slowly re evolved according to the animal genes, which also led to zombie of animals. This kind of virus is type 7 B virus. In addition, according to the special evolution of some special organisms, there are three types of type 7 viruses, namely type 7 CDE. Although the mummification time of the four BCDE viruses is slower than that of type A, they are all within 4 hours. However, it is precisely because of the rapid zombie time of terrestrial viruses, which are almost captured by destruction, resulting in serious damage to biological organisms, and the combat effectiveness, speed and life span of this kind of zombies are relatively shorter.

    The second is airborne virus.

    The main infection of this kind of virus is that the zombie time is generally less than 12-72 hours for creatures that can fly.

    Because the process of zombie transformation is relatively slow and the integrity of the body is preserved to a certain extent, this kind of zombie has fast flight speed, strong aggression and certain intelligence.

    There are three kinds of airborne viruses, namely type 7 F, G and H viruses!

    Finally, marine viruses, which mainly infect marine organisms and a few freshwater organisms, are mainly marine organisms.

    The number of marine viruses is large and complex, which is due to the infinite changes in the marine environment. Each virus has different evolutionary routes according to the different living environment. At present, it is known that twelve types of seven viruses have evolved, and the zombization time of these twelve types of seven viruses is about 24-48 hours.

    Therefore, zombies produced by marine viruses are also quite aggressive, and the number of marine zombies exceeds the sum of land zombies and flight zombies, which is the most threatening category to mankind at present. However, this is not the most terrible. The most terrible marine virus can survive in the sea water for 72 hours after it is free from the parasite. If the temperature is not high, it can even survive for 30 days. Therefore, all the oceans in the world have been occupied, and the beach line bordering the sea has become a dangerous place. There are not only a large number of marine animal zombies, but also fleshy coronavirus in the sea water, A little carelessness can infect.

    In addition to these three types of viruses, there are two types of type 8 viruses whose properties have not been studied yet.

    …………

    "Well, the corresponding relationship between corolla virus and zombie species is basically finished. You must keep these knowledge in mind, because this will be the main enemy you will face after you go to the battlefield, and it will also be one of the written examination contents of your recruit assessment. I hope you can go to the battlefield safely and go to the battlefield safely!"

    After the virus class, Zhou Yalan sat on the podium.

    She looked at the energetic young recruits below. Her heart was suddenly filled with tears.

    These teenagers are the flowers of the future of the motherland. They must have a great life in the future, but now they give their best life and youth without regret for the future of the motherland, the future of blue star and the future of human civilization, which is admirable and respected!

    Zhou Yalan also feels honored and proud to give lectures for these young heroes!

    At this time, Zhou Yalan suddenly remembered an episode in the classroom and asked, "by the way, who just proposed that our research speed can not keep up with the speed of virus evolution?"

    "Teacher, it''s me!"

    Lu Xiping stood up straight, raised his hand, and then sat down immediately. He was already a soldier.

    Zhou Yalan couldn''t help looking at Lu Xiping more and said, "first of all, I want to admit that our country''s current biotechnology can''t keep up with the evolution speed of viruses, which has also become the biggest distress for our researchers. I just want to know where you got this?"

    "It''s already obvious. If our research speed is fast enough, it won''t be so difficult to solve the global zombies. In addition, I thought of this when I heard your teacher say that the corolla virus has evolved many families of viruses." Lu Xiping said calmly, although he heard this conclusion in his dream last night, But in fact, he had thought about this possibility long before he joined the army. At this time, he just asked it according to the trend.

    Zhou Yalan sighed helplessly: "You''re right. Some superficial phenomena do explain the nature of things. With our current technology, it takes about 18 hours to analyze the genetic data of sarcocypsis virus, but the mutation speed of sarcocypsis virus has accelerated to once every 3 hours after evolution. Therefore, when our research results come out, the virus often mutates many times, or even recombines once, and we just got it The genetic data is basically useless. "

    "Isn''t there a better and faster way?" Lu Xiping frowned.

    Zhou Yalan smiled bitterly and said, "there must be some ways. At present, biologists all over the country are looking for it, but it will take some time."

    "I want to ask, have you ever tried to find out the mother virus of meat crown virus?"

    Lu Xiping suddenly made a startling remark, which aroused the laughter of many comrades in arms. It seems that Lu Xiping is a little arrogant. He is a doctor of biology. Do you need a recruit to teach him to do things? Moreover, they have never heard of the flow of corolla virus and mother virus.

    On the contrary, Zhou Yalan brightened his eyes and asked, "mother virus? How can you have this strange idea?"

    "Very simply, there has been an organized siege of zombies around the world. If there is no commander for command and coordination, how can this happen? If there is no commander in the virus, it must be scattered, and the threat to us should not be great."

    These views were actually heard by Lu Xiping from the two giants in his dream last night.

    At that time, after reading the genes of the coronavirus, the two giants made a hypothesis, that is, if they were faced with this virus, what methods could they use to solve the crisis?

    Among them, the male giant named Hengyi proposed that the corolla virus has shown an organized phenomenon, which shows that there must be commanders or command groups. If you can find the command virus and extract its genes, you can make targeted biological weapons or develop vaccines. In order to ensure its superiority, the mother virus generally adopts the most mature and more comprehensive evolution Route, which means that the mother virus must not mutate every 3 hours like ordinary viruses, which gives them a one-time opportunity to solve the crisis, but this opportunity is often fleeting!
