"Who the hell is that?" Li Huixian also helped Li Shenglong think, and the whole person panicked.

She never offends anyone, others bully her, she never bullies others, she has no enemies.

If you want to say that Cao Meng and them are indeed a little festive, but these people definitely don't have this ability.

The thought of having an unknown enemy hiding in the shadows, wanting to kill Christian Lee every day, and then they didn't know who this person was, Lee Hye-hyun felt extremely painful.

Wei Yanzhi said suddenly: "Listening to the driver's description, it seems that he is not a local, and the transaction carried out in the guest house should have come by train." ”

Christian Lee, who is also smart, understands what he means, so his face is a little surprised.

Li Huixian didn't understand and asked, "What do you mean?" Do you know anything? Do you know who it is? ”

Wei Yanzhi shook his head and said, "I'm just guessing, I'm wondering if it will have something to do with Shenglong's biological mother." ”

Li Shenglong said: "Except for them, I don't know any outsiders. ”

Li Huixian was shocked and puzzled: "How can that be? Why did her mother hurt Seung-ryong? Is she crazy? ”

"I don't know, it could be someone else."

Wei Yanzhi groaned and said, "You wait, I'll follow this line to check." ”

Wei Yanzhi came back that afternoon, his face a little heavy.

He stood beside Lee's bed and grinded his fingers, then said, "Do you want to hear the truth?" ”

Li Shenglong asked rhetorically: "Do you want me to curse?" ”

Wei Yanzhi: "......"

"Because it's hard to accept the truth, this girl should be your aunt's niece, she grew up in the Cui family, and that man is her own brother."

"These two people should be afraid that you will go back and compete with Zheng Jie for favor, so they will kill you."

"What?" Li Huixian was even more excited than Li Shenglong, and said, "Is it really their family who did it?" ”

Wei Yanzhi nodded: "It's for sure, they are in the city now." ”

Looking at Li Shenglong, he insisted in a tone: "I haven't asked your opinion, but I don't think I need to ask you about this kind of thing, I have already called the police." ”

Li Shenglong smiled: "If you ask me, I will scold you, this kind of person, of course you have to call the police." ”

Li Huixian didn't say anything, looking preoccupied.

After Wei Yanzhi left, Li Huixian sat on the edge of the bed with a worried expression.

Christian Lee asked, "Mom, what's wrong with you?" Ever since you found out who the killer was, you seem to be depressed. ”

Li Huixian changed her usual cowardly image, rolled her eyes and said, "Can I be happy?" ”

"I heard that your uncle and grandfather love you so much, I have thought about it, anyway, you are older, you have to go to school, and you need a better future, I want you to go back, but now, how can they treat you like this?"

"We don't want to rely on them, you haven't even contacted them, why do you want your life?"

"I want to go to the Cui family and say that the children were raised by me, they don't feel distressed, I feel distressed!"

Christian Lee's anger was also very angry, but her mother was so angry, she couldn't be angry.

Otherwise, there would be no comfort for the mother.

Li Shenglong took Li Huixian's hand and said, "Don't worry Mom, it's good to know who did it, I won't let them go anyway." ”

"And you also said that we can't afford to live, it's okay not to recognize them, don't we recognize them, isn't it better for our mothers?"

Li Huixian pouted: "Angry, the Cui family is very disappointing." ”

But some are destined not to disappoint.

The day Li Shenglong was discharged from the hospital happened to be the 27th day of the lunar month, and there were two days left for the Chinese New Year.

Zhong Huaijin mailed a package to Victor Lee.

There is a letter, a journal, two books, and local souvenirs.

The letter said that the vaccine he developed has entered the clinical trial stage, and there are no problems for the time being, and after the human trial, it can be officially put into production, and then it can be vaccinated to adults, and adults will be vaccinated without any problem.

Zhong Huaijin also said that once the vaccination campaign is carried out among children, it will be free, and then children across the country can be vaccinated to prevent diseases.

The journal naturally published Zhong Huaijin's papers on it, and these are his scientific research achievements.

He is now making attenuated vaccines, and he has heard that there are inactivated vaccines abroad, and he is moving closer to inactivated vaccines, hoping to make inactivated vaccines in the future.

He also said that if one vaccine is successful, the other vaccines will be successful, and he is confident.

When the time comes, our children will be able to be vaccinated from an early age and protected from the threat of disease and death.

In addition to writing about vaccines, a letter has only a few greetings.

But Victor Lee, who watched it, was a little sad and excited.

Open the vaccine book, which disease is fatal, and the people who grow flowers will live longer and longer, which is inseparable from the credit of the vaccine.

Of course, Zhong Lao and them are heroes.

In fact, about vaccines, Christian Lee, also knows a little.

For example, the inactivated vaccine that Zhong Lao said, in fact, for this disease, the attenuated vaccine is more protective to children than the inactivated vaccine.

Because the disease can be spread through feces, mainly through feces.

This makes it easy to spread in the community.

The difference between attenuated vaccine and inactivated vaccine is that the attenuated vaccine is still toxic, and after the attenuated vaccine of this disease enters the human body, it will also be excreted through feces, and then spread out, so that children in other communities may be exposed to it, which is equivalent to a vaccination.

This inactivated vaccine does not have this effect.

This is for the entire population, and the attenuated vaccine is more protective against the population.

But when it comes to individuals, there is a 1 in 250,000 probability that this attenuated vaccine will cause illness in children.

This data is based on years of clinical experience.

Strange to say, every time so many children are vaccinated, there will definitely be one who gets sick.

Therefore, this virus has always been scarce, and even in the era when Christian Lee's life was lived, it was not completely eradicated by humans.

Like the smallpox virus, except for laboratory remains, it can no longer be found in humans, and we can declare it eradicated by humans.

Therefore, if this virus is killed by inactivated vaccines, it is relatively safe for individuals, but the protection of the group is not as good as that of attenuated virus.

Therefore, later our country implemented the first two injections of inactivation and the last two injections of drug reduction.

In this way, the vaccine can be safely maximized.

Therefore, it is not possible to simply say which vaccine is good and which vaccine is bad, each has its own advantages and disadvantages, and it is still difficult to choose for decades.

The same is true for other vaccines, which need to be analyzed in special circumstances.

Of course, Li Shenglong couldn't write in such detail, otherwise Zhong Lao would doubt her, and she would turn what she learned into nonsense and tell Zhong Lao.

Then he asked Zhong Lao another difficult question.

I was not in good health and went for a check-up.

The result of the examination was that there was nothing wrong......

Let's do more tomorrow, I go to bed early, and everything should be fine.

Good night everyone.
