Since Happy came to the village, he used the Heaven and Earth Net Array to besiege the zombies, and after the five thunders burned the zombies, the number of zombies has been controlled, but the zombie virus still exists in large numbers, and it will still be transmitted through humans and domestic animals, which is also inevitable, just like Tu Xingxing said, although he is superb, but he only treats the symptoms but not the root cause.

Fortunately, Professor Pang has found the antigen body of the zombie virus, so now we just need to collect human blood samples and let Professor Pang conduct research.

Not only that, Professor Pang also said that although there is now an antigen body of the zombie virus, this zombie virus is pervasive and can be transmitted through many ways.

The first is birds, which are more susceptible to infection, and zombie pathogens are more infective through sick birds, which can spread faster than terrestrial transmission.

The second is rodent transmission, such as rats, cats and dogs, which are extremely contagious and mutate.

The third type of insect transmission, insects are susceptible to infection, and insect carriers can increase the infectivity and mutation rate of pathogens in hot environments.

The fourth type of blood transmission, in which pathogens are transmitted through human blood.

The fifth type of livestock, which is more susceptible to infection, will increase the infectivity and mutation rate of pathogens in rural areas.

The sixth wild animal, after Huangquan Village, there is a dark forest, where it is all primeval forest, if the virus infects wherever it is, those wild animals are infected with the virus, it is unimaginable.

The seventh type of airborne transmission, which is also a kind of transmission of horror after all, allows the zombie virus to attach to the airborne dust, which will enhance its transmissibility, especially in dry environments

The eighth water source spreads, in addition to the human body, pathogens can also live in mountain springs, streams, and it is terrifying to think about.

However, Happy also said that although he set up the Tianluo Net Array in Huangquan Village, this kind of array also has limitations, that is to say, after a certain time, the Heaven and Earth Net Array will automatically disappear, if at this time, we have not found enough blood for Professor Pang to study, and Professor Pang has not found enough virus antigens in time.

Then, the above eight transmission routes will be spread one by one.

Not only that, but the zombie virus has also begun to evolve, its cold resistance has increased, and the virus can tolerate low temperatures and cold weather.

The second zombie virus also has the ability to resist heat, that is, the virus can tolerate high temperatures and hot weather.

Third, drug resistance, general antibiotics, has been ineffective against zombie viruses.

Fourth, genetic enhancement, which is why zombies have become powerful, and there are even giant zombies, which are fundamentally zombie virus enhancement.

Fifth, it is bacterial resistance, bacteria can produce cell walls to protect themselves from any environmental influences, that is, zombie viruses can survive and spread in almost any environment.

However, people who were infected with the virus by zombies were also divided into two types.

One is direct infection, direct infection, simply put, it is directly bitten by a zombie, and within five minutes, it becomes a zombie.

The second type is indirect infection, such as being infected by domestic animals and birds, which is called indirect infection.

Indirect contagion has the peculiarity that it doesn't immediately turn people into zombies, but it does have an omen.

For example, when people are indirectly infected with the zombie virus, they will have the following symptoms.

First, nausea.

Inflammation of the gastric mucosa makes the patient feel nauseous, and kissing also has the potential to spread

Second, vomiting

The vomit ejection combo expels a large amount of infected vomit, and will also infect other people through the vomit, which is somewhat destructive.

Third, pulmonary edema

The loss of cardiac energy can damage the respiratory system, while the pathogen spreads to the surrounding environment, which is potentially fatal.

Fourth, coughing, which has a certain chance of releasing pathogens into the surrounding environment to enhance the ability to infect, especially in densely populated areas.

Fifth, fever

The patient's body temperature is elevated, highly contagious, and can lead to severe dehydration.

Sixth, patients with skin injuries have broken epidermis and weak resistance, and are easily infected by zombie viruses.

Seventh, the rash

People who have chickenpox and become painful on their skin are also contagious

In short, indirect infection will make people have different symptoms, which also depends on their own constitution, and the onset is different.

Cui Hao and Liu Xin, three of us, after going up the mountain, found a lot of live mouths and took blood samples, but the happiest thing for me was that I finally found my grandmother.

"Grandma, it's great, it's good to see you're okay!"

I looked at my grandmother with excitement and saw that she was all right, and I was deeply embedded in my grandmother's arms, which made me feel very relieved.

"Xiao Zhi really thank you, you protected Meng Meng along the way."

Grandma looked at Cui Hao and smiled with satisfaction, and kept thanking Cui Hao.

"Grandma, you misunderstood, he's not Cui Zhi......"

"But he ......"

Just when his grandmother was wondering, Cui Hao took the initiative to introduce himself.

"Hello grandma, I am Cui Zhi's brother Cui Hao, I was born to Cui Zhi's mother, we are twins, so I let you look away."

Grandma looked Cui Hao up and down again, only to find that the two were indeed different, Cui Zhi sometimes behaved frivolously and looked like a child, while Cui Hao seemed to be a responsible person, and his eyes were a lot calmer.

Grandma's eyes did not take her eyes off Cui Hao, but kept looking at him, as if she wanted to see Cui Hao through, and grandma nodded while looking at it, and said, "En, young people are still good, you have to take good care of Mengmeng in the future." ”

"Mengmeng, you have to have less contact with Cui Zhi, I think Cui Hao is not bad."

Grandma suddenly said such a sentence, which made me a little curious, grandma just saw Cui Hao for the first time, so she stood on his side, but when grandma mentioned Cui Zhi, I was a little unhappy, and pouted: "Grandma don't talk about Cui Zhi, I have broken up with him." ”

"Okay, okay, it's best to break up."

I didn't expect my grandmother to be happy for a while, and I didn't want to mention him, so I changed the topic and said, "Grandma, why are you alone, Uncle Ming?" ”

"Didn't Uncle Ming go down the mountain to look for you, or did you come down the mountain with noodles, have you seen noodles?"

I nodded in surprise and said, "I've seen the noodles, and the noodles said that I'll send you a message back." ”

"That's weird, Noodles and Uncle Ming haven't been in contact with me for several days, this matter is too strange."

Grandma's gloomy eyes made people look frightened, she looked at the mountains and forests in the distance, squeezed her hands violently, and said, "No! I'm going to look for Uncle Ming, maybe something happened to them. ”

"Grandma! You be careful. ”

Looking at my grandmother's rushing back, I was worried for a while, but I also knew the relationship between my grandmother and Uncle Ming, although the two of them had not broken it over the years, but everyone in the village could see that they had each other in their hearts, but my grandmother was unwilling to pierce the layer of window paper, and Uncle Ming followed my grandmother.
