Zhao Guijie stopped talking as he spoke. Sometimes playing the harp to a cow isn't all about the cow. Knowing that the cow can't understand, you still play hard, who is stupid? So the big expert immediately changed his strategy: "To put it simply, the deadly virus is extremely tenacious. Even if the earth star is gone, these invisible demons can still live. ”

Yang Xiaohai said: "According to this, we are struggling with our lives, just to be able to choose our own way of death?" No matter how special I am, no matter how special I am, no matter how much I have the aura of the protagonist, I can't do anything better than the Earth Star! ”

Zhao Guijie's cheeks trembled, and he said weakly: "Young man, I just can't bear it." If it's really a dead end, I'll still have to spit on you here. ”

Zhao Guijie talked for a long time and felt thirsty. "Tired boy, get the old man a drink." As soon as the words came out, I felt inappropriate. It is not surprising that the house is full of garbage, even if a few "infected" are buried. Sure enough, Yang Xiaohai's big feet pulled and pulled out a bottle of mineral water between a pile of fish bones and empty wine bottles. Yang Xiaohai retracted his feet without socks, but found that the slippers were buried in the garbage heap. He picked up the water bottle and glanced at it, and said with relief: "Lao Zhao, you are so lucky, it will expire in two weeks." Zhao Guijie suddenly stopped being thirsty.

"As soon as I entered the door, I said that the virus is the strongest and the weakest existence. The Creator will never allow absolute perfection to exist in the world. The more powerful it is, the easier it is to collapse from within. As the saying goes, there must be fragrant grass within 100 steps, and a drink and a peck are like heaven. ”

Yang Xiaohai's eyes began to drift, and his body was tilted towards the bed. "I'm sure you've heard the term 'Infected' and its mutants. The reason for these names is that the scientific research power of the whole Earth star is too scattered. You study yours, I ponder mine, and the whole planet's understanding of the 'infected' is superficial, both correct and inaccurate. ”

When it comes to familiar things, Yang Xiaohai cheered up and didn't let himself fall asleep. "As I said, the virus is very viable. But another of its abilities is even more powerful, and that is the ability to mutate. It took two months for us to finally determine the pattern of variation. At the time of the initial outbreak, the virus showed great lethality and transmissibility.

But to be honest, at that time, if the global force was mobilized, a scientific and technological breakthrough would have solved the problem. Of course, there is no regret medicine sold in the world, and it is useless to say more. In short, the virus at that time overturned the earth with a huge number of infected individuals. The viruses are all the same, hideous and singular. If only a vaccine had been developed by then......

Cough...... In short, the viruses of that time period are collectively known as the T-virus. It is an unknown virus that is transmitted through bodily fluids and acts on mammals. ”

"Only on mammals? Hehe, I already knew this. As soon as I left the house, I dared to eat crabs. Yang Xiaohai thought that when he first arrived at the reservoir, he couldn't help but be proud of his courage.

But the big expert was obviously untouched. Zhao Guijie was indifferent, and continued: "The appearance of the T virus is very similar to the flu virus, at least it is still familiar to us. A few months after the apocalypse, the virus was completely transformed. Words are a bit hard to describe. When you have time, you come to the institute, which is more intuitive under the microscope. ”

"I said Lao Zhao, early in the morning, you came to the door to give me popular science virus knowledge?" Yang Xiaohai has a natural aversion to tirades.

"Be patient, I've condensed dozens of pages of professional reports." Zhao Guijie can't do anything about the old otaku. You know, these things he said are the most cutting-edge virus materials. If the wind is released, I don't know how crazy it will be. The more you know about the virus, the better your chances of survival!

"T viruses converge and devour each other over time. And interestingly, their number is not decreasing. Through observation, we found that it autonomously mitoses, which in turn leads to self-mirroring. On the one hand, they devour each other, and on the other hand, they replicate themselves. The rate of engulfment and replication is almost the same, so that the number of virus populations remains at a stable level.

The part that devours each other is the survival of the fittest, and a new type of virus similar to the T virus, but much more powerful, has evolved - D virus! Individuals infected with the virus tend to be stronger and more agile than the host of the T-virus. Due to the uncertainty of engulfing each other, D viruses also show diversity, and their hosts are also different.

Crabs, machos, jumps, virulences, and other variants like the ones you described are all D-virus 'infected'. Oh, the dogs at the base, the mammals that survived in the wild. About them, we'll talk about that later. ”

A hearty passage made Zhao Guijie get back to his time as a university lecturer. Unconsciously, he returned to the lecture hall with bright windows, and Yang Xiaohai became a student. The old man's mouth is no longer dry, and the smell of the house is no longer unpleasant. He picked up the mineral water bottle on the ground, twisted the lid, and poured half a bottle in a few sips.

Energetically, he continued: "The D virus is more powerful, agile, or special than the T virus. It's a bit of a misconception to describe it, so I'll put it another way. The D virus is like the emperor to the people.

Under the microscope, it can be clearly seen that once the D virus is born, it will control the population of the T virus that gave birth to it. After a while, a new D virus is born, which will be swallowed by the previous D virus. And by engulfing, the D virus that was born first will obviously grow several times.

This kind of behavior, I believe, should also be manifested in the host. From birth to engulfment, the survival time of a single diseased strain is very short. And most importantly, the source of the power of viruses to devour each other is the human organism. Ironic, right? As the spirits of all things, we are fed by viruses that live for a very short time. That's why I say that viruses are strong and fragile. ”

Yang Xiaohai went back to bed. Not to mention, lying down to listen to the lecture is more comfortable than sitting upright. As soon as his spirit relaxed, Zhao Guijie's words were listened to a little bit. With the old academician's subdued tone, Yang Xiaohai remembered the time when he was an "infected".

In the dilapidated "shelter", isn't "Little Arnold" the "infected" of the D virus who controls the scene? I didn't understand it at the time, but now I have found the answer.

"Co-authored 'Little Arnold' and raised all the T-virus infected people, including me. Thanks to me, I don't have a chance, if I swallow a crystal brain at that time, I will definitely be opened by 'Little Arnold'. Yang Xiaohai was very afraid.

"Since the T-viruses devour each other, they can produce stronger D-viruses. Will the T viruses also devour each other and create the S virus, that is, the super-giant variant? "Yang Xiaohai drew inferences from one another." This student's attitude in listening to the lecture is commendable, and his brain is very active. It's okay to use your brain, don't always be proud of being uneducated. ”

Zhao Guijie looked pleased. "Are you complimenting me?" Yang Xiaohai didn't appreciate it. "That's right, there has always been a situation of engulfment between viruses. I even suspect that they are made to devour. Not only do they attack each other, but even the host must devour and chase. It's just that I haven't found the reason why only mammals are chosen. ”

"Why do D virus hosts and S virus hosts look like they have taken aphrodisiacs when they see me?" Yang Xiaohai looked back on the past and felt aggrieved. The T-virus "infected" is okay and only uses him as a ration. But the D and S virus "infected" treat him as a flower girl, which is beyond words.

Every time I see him, regardless of it, I chase and fight hard, and I always have the strength of "I only have you in my eyes"; After a long time, the innocent old otaku's careful liver was very hurt.

"When my God? Know everything? Zhao Guijie cleared his throat and planned to continue drinking water. Glancing at the half-bottle of mineral water in his hand, the gray shell, he was puzzled: "Such a dirty thing, is it really the bottle I drank just now?" ”

The end times have changed many people, and the big experts no longer bother with these little things as soon as they change their minds: "After repeated verification, in addition to determining the order of virus changes, we also found that the D and S viruses are extremely unstable. Almost all the time, the traits are changing. More information on the D virus. But the S-virus is still poorly understood. In the final analysis, there are still too few samples, and the data is relatively simple. Later, you can get more samples of the S-virus. ”

Yang Xiaohai shrunk in the quilt to listen to the story, and coughed violently when he heard the words. He choked on saliva, couldn't breathe for a while, and his face turned red. Just kidding, why don't you go to the backyard to catch chickens? Are Type S mutants so easy to get along with?

"I heard that you took over the task of the national company to find the first generation of viruses, right?" Zhao Guijie suddenly changed his words and stopped continuing the class. "What, you're going too?"

Yang Xiaohai asked casually. "! My battlefield is here, why are you running so far? Besides, I play with my brain, and I work with my heart; You have to come to the work of labor. ”

The big experts will talk about "fear" above board. "No matter how the state company determines the location, I personally think that the benefit of this trip is not much. The virus is constantly changing, and the first generation is not the first generation, so it is of little use. ”

"Uh...... You are an academician of the state-owned company. Yang Xiaohai reminded in a low voice. Science knows no borders, and it is scientists who have boundaries. As far as the matter is concerned, I will say this everywhere. "It seems that the temper of the big expert is also quite stubborn.

"Then what's the matter with me and the little girl, Winnie, and Huang Lao?" Yang Xiaohai threw out the long-standing questions that had been entrenched in his heart.

"I seem to be immune to the virus, and I can switch between the "infected" and humans. They ...... after drinking my blood."

Yang Xiaohai closed his mouth suddenly. Zhao Gui's eyes in front of him gradually widened, and they were about to burst out of their sockets. The old otaku suddenly remembered: The matter of the small group of four people seems to have never been communicated to outsiders. Yes, anyway, we have to rely on the power of science, so I just said it.

Yang Xiaohai's arrogant temperament made him pour out all the secrets—not to mention immunity, his blood could also restore the infected to their senses—at the cost of only a slight sequelae.

"Oh my God! That's the second reason why I came to you. Through the dark web, I have not found a single natural immune one in the stars, not even asymptomatic carriers. I wanted to ask you to help me find it, but I didn't think about it......"

"Didn't you admit that you wanted to find him thousands of times?" Yang Xiaohai rarely remembered an ancient word, and hurriedly answered.

“…… I didn't think it was dark under the lights, and the only breakthrough was at the base. The big expert replied dryly.
