In fact, at this moment, Yu Ying still can't judge whether the virus is highly lethal?

After all, the original owner died too early, and died just before the catastrophe began. It can be said that even the initial results have not come out, which really makes Yu Ying unable to judge.

But one thing Yu Ying can be sure of is that the virus must be highly contagious, otherwise so many people would not have gotten sick.

The channel through which the virus spreads is most likely airborne, which is also calculated by Yu Ying.

You must know that the Ebola virus, as the deadliest virus in the world, is not transmitted through the air, but through physical contact, such as contact with body fluids, skin, mucous membranes, etc., which causes the Ebola virus to wreak havoc mainly in Africa.

However, the confirmed fatality rate of Ebola virus patients is as high as 80%.

This makes it the Ebola virus, a biosafety level 4 virus.

However, the conditions that required physical contact to successfully transmit the virus allowed Yu Ying to basically rule out the Ebola virus, and there was no skin ulceration in the original owner's memory.

So what is the virus? Yu Ying can only guess that Yu Ying has not studied any virology, but has only read some books.

Even in order to complete the task, Yu Ying did not choose to study virology, otherwise once the epidemic broke out, those who studied virology would definitely be recruited, what should the Liu family do at that time?

So Yu Ying didn't plan to become a scientist, but took another path.

In fact, Yu Ying suspected that the reason why the original owner was not infected was not that he was not really infected, but that he should have developed antibodies soon after being infected, so this virus is properly contagious, and almost everyone is recruited.

However, some people have a very strong immune system and directly resist the past, and the symptoms do not occur.

Therefore, since Yu Ying came over, she deliberately gave the Liu family medicine to enhance physical fitness, not to mention, but also strengthened the physical exercise of the whole family, so the Liu family's own immune system has been greatly improved.

Judging from the past few years, the effect is still quite good, there are some flu occurrences in the rice country every year, and the Liu family, including Liu Changgeng, is fine, and they easily pass the test. This time is the time to put the results of all this to the test.

Seeing this situation, Yu Ying was a little sure.

But at this time, Yu Ying was still a little uneasy in her heart, how to go in the future?

Liu's father and Liu's mother are in good health now, as long as they don't lag behind.

The hope of the Liu family is Liu Changgeng, after Yu Ying came back, she found that her younger brother Liu Changgeng had grown taller, and this child was when he was growing taller, and he hadn't seen him for nearly a year, and he had changed a lot.

What makes Yu Ying happiest is that even if Yu Ying is not there these days, Chang Gung still works hard to keep exercising.

Yu Ying tried his skills, and he made great progress compared to before.

And Liu Changgeng was surprised and happy when he saw his sister come back, but because the little guy felt that his sister hadn't come back for a long time, he just didn't love him, so he tried to hold his little face and contain the joy.

It's a pity that Chang Geng is still too young, so the joy in his heart still can't be hidden, Yu Ying looked at it, stretched out her hand to rub Liu Chang Geng's little head, and then said: "Xingxing doesn't want my sister to come back? Why do you look unhappy?"

I saw Liu Changgeng raise his little head, snort from his nose, and said, "Don't call me Star, call me Tom." ”

You must know that Liu Changgeng is also a popular figure in school, and his Chinese kung fu has attracted many fans and sisters, but he is much stronger than Yu Ying at that time.

"Tom?" Yu Ying read the English name with some amusement, then she stretched out her hand, nodded Liu Changgeng's nose, and said, "Actually, Xingxing, you are not young now, you should know that your Chinese name is: Chang Geng." ”

"Know!" Liu Changgeng said.

"Do you know? In fact, the name Chang Gung comes from the Tai Bai Xing in Chinese mythology, and the name is Chang Gung. Yu Ying said.

At that time, when naming her little brother, Yu Ying intervened and insisted that she give her younger brother a Chinese name, so Yu Ying gave him a name that was the same as Tai Bai Xing, nicknamed Xingxing.

When Yu Ying told the origin of this name, Liu Changgeng knew that his name had such a lofty origin.

"Actually, star, if your name is Tom, it's hard to say, you look at Tom, my sister first thinks of the Tom in "Cat and Mouse". When she said this, Yu Ying didn't say any more.

Because of hearing this, Liu Changgeng's face turned green all of a sudden.

Tom has the same name as that stupid cat, which is not a good feeling.

This is not comparable to Chang Geng, the Chinese name that means too platinum star, at all.

Liu Changgeng couldn't care about being angry with his sister at this time, and just one sentence came to his mind: I don't want to call Tom again, no wonder someone wants to laugh when they hear this name.

In fact, Yu Ying deliberately made a joke with Chang Geng, but the child really took it seriously.

Chang Gung didn't know about this, he made up his mind, he would never be called Tom in the future! Everyone else would call him in the future: Chang Gung!

Seeing that Christmas is coming, Yu Ying still doesn't know the future developments, although there will be no mass extinction of humans, but I don't know when scientists will be able to develop a vaccine to deal with it?

Although a vaccine can be developed, I don't know what an effective vaccine can be?

In fact, a vaccine for the Ebola virus is said to have appeared, but there is no chance to confirm whether the vaccine is effective.

So, Yu Ying doesn't know how much time it will take for the vaccine to come out this time?

In addition, Yu Ying also knew that the danger factor of this mission of the Great Catastrophe was as high as five stars, so maybe Yu Ying would die somewhere in the mission.

So Yu Ying took time out to play with her family, and even took a lot of videos, which can be regarded as a memorial for them.

It's a pity that the happier things are, the more difficult it is to keep them sometimes, and maybe that's how happiness will be precious and nostalgic.

In this way, that happy time is like the quicksand in the palm of your hand, disappearing little by little.

That moment was finally approaching, and Christmas Eve was not peaceful.

It's just that at this moment, except for Yu Ying, no one knows that they will soon face everything dark, because of the raging virus, the original order established by human beings has been challenged.

In fact, Yu Ying couldn't make up her mind at this moment, should the Liu family be exposed to the dangerous virus early according to the life of the original owner, or should they simply isolate themselves from the virus?

If they had been exposed to the virus earlier, Yu Ying would have known if they would have survived this hurdle?

In fact, some viruses, although highly contagious and highly deadly, will gain lifelong immunity after one infection.

However, some viruses are constantly mutating in the process of circulation, resulting in almost zero immunity to new viruses, and you have to start all over again if you want to get antibodies.

I just don't know what kind of virus is the virus that has swept the world?

In fact, if you come into contact with the virus early, you may be able to find a way to deal with it.

If after encountering that kind of virus, it can produce lifelong antibodies, then in this catastrophe, Yu Ying at least does not have to worry, the Liu family will get sick again.

In this way, Yu Ying thought about it for a long time, and finally decided to contact the virus early, if the contact was too late, then maybe Yu Ying was not by their side at all, how could she take care of them?

It's better to get in touch early, if you have a disease, you can get out as soon as possible, and you can cure the disease.

On the day of Christmas Eve, taking advantage of the crazy discount, the Liu family did not go to the mall without vulgarity, in fact, although everyone in the rice country has payment measures such as credit cards, paper money is still in circulation.

Seeing this green banknote, Yu Ying had a lot of speculation in her heart, could this be one of the culprits of this catastrophe?

In fact, after Yu Ying passed through, she has been looking for the vector of the existence of the virus, after all, it is not easy to let so many people be recruited.

After all, this is the native of the rice country, and it is absolutely impossible to use any planes and throw any viruses, if that is really the case, then the military will participate in nine times out of ten.

With Yu Ying's understanding of the rice country, it is somewhat possible to carry out biochemical actions against some unsightly countries, but it is impossible to do so to her own people.

In addition to putting viruses on banknotes, there is also a possibility of contracting the virus, that is, some people take advantage of the Christmas Eve event, and the crowds are not good, so they take the opportunity to put some viruses that can be transmitted in the air.

In fact, in the previous life, the Liu family participated in both activities.

In this life, Yu Ying didn't plan to interfere with the activities of the Liu family, so she wanted to see which way it was to spread the virus this time.

And Yu Ying decided to get some banknotes to see if there would be the most primitive virus plants?

Then Yu Ying plans to study it herself, and when she finds something, she plans to send the research results back to China anonymously, which can be regarded as a contribution to China.

So Yu Ying quickly collected a lot of things and put them in the prepared place.

Fortunately, Liu Changgeng was young and sleepy early, so the Liu family went home early.

So Yu Ying returned to her room early, she set up a small laboratory in her room, and even took protective measures, you must know that some viruses are very virulent, and the protection is not good, but it will cause a big thing.

In fact, Yu Ying found a lot of viruses on the banknotes, and after isolating them one by one, Yu Ying found a new virus with a lot of numbers, and this new virus is not one of the existing viruses.

Seeing all this, Yu Ying felt that she had a little headache, such a large-scale virus spread is absolutely impossible to do alone, so the people who do these things, do they know that the Pandora's box they opened this time is a plague?

Of course, there is no shortage of people's brains who have been kicked by donkeys.

When detecting the virus in the air, Yu Ying found that there was almost no such virus, but it should appear in a few days, so the vector of the virus that appeared first can be basically determined, which is those banknotes.

But the virus can spread in the air, which is the most annoying.

Of course, Yu Ying doesn't plan to do any virus vaccine, after all, she is not a virologist, and there are a lot of things in the series of virus inactivation, and it will take a lot of time to really apply it to people.

In fact, Yu Ying has refined a lot of traditional Chinese medicines, some of which improve the body's immunity, and some of which are useful for killing this new virus.

However, Yu Ying knew that she had too little time, so she could only study it superficially.

In fact, Yu Ying soon discovered that this virus had a strong ability to survive, and in the cold, it still survived for a long time without a host.

When she saw this, Yu Ying's face was not very good-looking, and then she began to pay attention to the pills she had already refined for the Liu family.

What will be the situation in this virus war? Yu Ying really can't speculate.

In fact, Yu Ying is sure of the virus this time, due to human factors. I just don't know if this person who made the virus has made a vaccine?

It's just that at this moment, Yu Ying was a little skeptical.

Because this kind of person who dares to create a new virus belongs to a kind of crazy person, and normal humans are not necessarily the same idea, it is difficult to guess.

Thinking of this, Yu Ying shook her head, there may or may not be a vaccine.

Then Yu Ying began to observe the culture tank she had made, in fact, there were those viruses in the current medicine.

Of course, some medicines seem to be useless at all, and the virus is still growing wildly, but Yu Ying still decided to keep it.

The virus in some drugs is obviously inhibited, and the rate of increase is not fast.

But this is only the first day, and Yu Ying has to observe for a few more days.

Then Yu Ying went to rest, after all, everything in the future is a big battle, so Yu Ying must maintain her physical strength.

In addition, Yu Ying also purchased a lot of things this time, that is, within half a year, there was no crisis of staple food.

Of course, vegetables and the like, it's hard to say, after all, that kind of thing can't be stored for too long.

There are some dried fruits or something, and there are all kinds of vitamin pills.

With these, Yu Ying felt that the Liu family would not starve to death at least. And if the crisis cannot be resolved in half a year, I am afraid that the government will fall absolutely and new rules will appear.

At that point, the choice is to be.

I just don't know how the family will be protected when I join the DHS's secret service organization this time?

In fact, Liu Changgeng has grown into a child soldier, able to fight and run, and even Yu Ying specially customized bulletproof clothing for him, but Chang Geng is still too young to support this family, so let's see what protection they will get, right?

The next day was Christmas, and Dad Liu drove to work early in the morning, as a Chinese, he didn't care much about Christmas, so he was always on duty on this day, and this time it was the same.

Of course, Yu Ying didn't plan to go out today, in fact, at this time, people who are not in good health are already having some physical problems, so it is better for the family to stay at home honestly.
