Traveling through the 80s, the beauties in the courtyard can't be provoked

"Then who is it?" Li Huixian also helped Li Shenglong think, and the whole person panicked.

She never offended anyone, it was others who bullied her, she never bullied others, she had no enemies.

It's true that Cao Meng and the others have a bit of a festival, but these people definitely don't have this ability.

The thought of an unknown enemy hiding in the dark, trying to put Li Shenglong to death every day, and they still don't know who this person is, made Li Huixian feel extremely painful.

Wei Yanchi suddenly said: "According to the driver's description, it seems that he is not a local. The transaction at the guest house should be by train."

Li Shenglong is also considered smart, and he somewhat understood what he meant, so his face was a little surprised.

Li Huixian couldn't understand, and asked, "What do you mean? Yanji, do you know something? Do you know who it is?"

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

Li Shenglong said: "Apart from them, I don't know any outsiders."

Li Huixian was shocked and puzzled: "How could it be? Why did her mother hurt Shenglong? Is she crazy?"

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

Wei Yanchi pondered for a while and said: "You wait, I will check along this line."

Wei Yanchi came back that afternoon with a heavy expression on his face.

He stood beside Li Shenglong's bed, rubbed his fingers, and said, "Do you want to hear the truth?"

Li Shenglong asked back: "Do you want me to curse people?"

Wei Yanchi: "..."

"Because the truth is quite difficult to accept. This girl should be your aunt's niece. She grew up in Cui's family since she was a child. The man's is her own brother."

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

"What?" Li Huixian was more excited than Li Shenglong, and said, "Did someone from their family really do it?"

Wei Yanchi nodded: "It's certain, they are in the city now."

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

Li Shenglong smiled: "If you ask me, I will scold you instead. Of course, this kind of person should call the police."

Li Huixian didn't make a sound, appearing preoccupied.

After Wei Yanchi left, Li Huixian sat by the bed with a worried face.

Li Shenglong asked: "Mom, what's wrong with you? Ever since you found out who the murderer is, 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 grandparents love you so much. I've already thought about it. Anyway, when you grow up, you have to go to school and 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 talk to Cui's family, the child was raised by me, they don't feel bad, I feel bad!"

Li Shenglong was also very angry at first, but when his mother was so angry, she couldn't be angry.

Otherwise, there is no comfort for the mother.

Li Shenglong took Li Huixian's hand and said: "Don't worry mom, just know who did it, I won't let them go anyway."

"And you also said that it's not that we can't afford to live anymore. Just deny them. Isn't it better for us to deny them?"

Li Huixian pouted and said, "Angry, the Cui family is very disappointing."

But some are not destined to disappoint.

The day Li Shenglong was discharged from the hospital happened to be the 27th of the twelfth lunar month, and there were two days before the Chinese New Year. The post office was on holiday, but the postman was more responsible and delivered all the letters that everyone had backlogged.

Zhong Huaijin mailed a package to Li Shenglong.

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

The letter said that the vaccine he developed had entered the clinical trial stage, and there were no problems for the time being. After the human trial, it can be officially put into production, and then it will be vaccinated for adults. If there is no problem with the adult vaccination, it will be given to children.

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

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

What he is doing now is an attenuated vaccine. He heard that there are inactivated vaccines abroad, and he is moving closer to inactivated vaccines. He hopes to make inactivated vaccines in the future.

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

At that time, our children can be vaccinated from an early age to avoid the threat of disease and death.

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

But Li Shenglong looked sad and excited.

Looking at the vaccine book, any disease is fatal, and the people who grow florists will live longer and longer, which is inseparable from the credit of the vaccine.

Of course, Mr. Zhong and the others are heroes.

In fact, Li Shenglong also knows a little about vaccines.

Like the inactivated vaccine that Mr. Zhong said, in fact, the attenuated vaccine is more protective for children than the inactivated vaccine for this disease.

Because this disease can be transmitted through feces, mainly through feces.

This makes it easy to spread in the community.

The difference between the attenuated vaccine and the inactivated vaccine is that the attenuated vaccine is still toxic. After the attenuated vaccine enters the human body, it will also be excreted through the feces and then spread out. In this way, children in other communities may come into contact with the virus. It's like getting a vaccine.

This inactivated virus vaccine does not have this effect.

This is for the whole group, and the attenuated vaccine is more protective for the group.

But when it comes to individuals, this attenuated vaccine has a one in 25 probability of making the child sick.

This data is derived from years of clinical experience.

Strange to say, every time so many children are vaccinated, one of them will definitely get sick.

So this kind of virus has always been rare, and even in the era when Li Shenglong lived, it was not completely wiped out by humans.

Like the smallpox virus, except for laboratory preservation, it can no longer be found in human beings, so we can declare that it has been eliminated by human beings.

Therefore, if this virus is inactivated, it is relatively safe for the individual, but the group protection is not as good as the attenuated virus.

So later our country implemented the first two injections to inactivate and the last two injections to attenuate the virus.

This can maximize vaccine safety.

Therefore, we cannot simply say which vaccine is good and which vaccine is bad. Each has its own advantages and disadvantages. It is still difficult to choose after decades.

The same is true for other vaccines, which require special analysis in special circumstances.

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

Then he asked Mr. Zhong another problem.

I'm not feeling well, so I went for a checkup.

The test result is that there is no problem at all...

More updates tomorrow, I'll go to bed early, everything should be fine.

Goodnight everybody.
