As for the matter of checking the palace ban, it can't be said to the outside, so the trial of 100 households given by Liu Shouyou can be regarded as the past! At least with this title, Liu Haojia will be considered to be in the middle and high-level of Jinyiwei, and it will be more convenient to act in the future!

More than three months passed quickly, and just when Liu Haojia thought that he needed to lie dormant for longer, suddenly a news was sent to Beijing by a fast horse: smallpox plague had occurred in a county town in Henan, and there were already eleven villages in the affected places, and the situation was critical!

When Liu Haojia received the news, he first sighed with emotion, and felt that the health and epidemic prevention work in the Ming Dynasty was really poor! Then he was horrified!

Because at this time, I figured out that I didn't come with a physical body when I came to Daming, and the body that took over was an authentic Ming person, and this body was not protected by any vaccination! In other words, if he gets the plague now, he will have to take his life to carry it! If you can carry it, you can carry it, but if you can't carry it, it will be a death! This made him a little frightened!

During the time he came to Daming, he already had a deeper understanding of Daming's medical system. Compared with the modern medical system, everything Daming does is scum, but it is much better than Europe, where only bloodletting and enema are used!

Although Daming's medical system has such and such problems, it is the first system in the world that has a heritage and can systematically carry out medical work! One of the important reasons why Han culture can be passed down is that it has a large population! And one of the important reasons for the large population is that there is enough medical treatment!

Although the level of traditional Chinese medicine at this time was very low, and even mixed with a large number of witchcraft rituals, there was no epidemic that swept the whole world on the land of the Central Plains, and the medical system of traditional Chinese medicine contributed a lot! You must know that several large-scale plagues in Europe affected almost the whole of Europe!

Liu Haojia immediately thought about it after breaking out in a cold sweat, he felt that the appearance of smallpox this time was an opportunity for him!

On the one hand, he can use this smallpox to make a vaccine so that he and his family can be vaccinated. Another key reason is that if cowpox is really successful and promoted to the world, he will really make a big contribution! Relying on this merit, not to mention promotion, it is possible to be knighted!

Thinking of this, Liu Haojia sketched a plan in his heart, and immediately asked to see Emperor Wanli. Emperor Wanli received him as fast as he usually did.

In the imperial study, Liu Haojia got up after saluting Emperor Wanli. Emperor Wanli asked, "Is there anything important that Liu Qing's family is in such a hurry to enter the palace this time?" Could it be that those mysterious people have news? ”

Liu Haojia shook his head and said, "I'm sorry, these people don't have any news. The minister entered the palace because of smallpox! The minister wants to go to Henan for disaster relief! ”

As soon as the words fell, Emperor Wanli said loudly: "No! This time Henan is making smallpox, if it is infected, there is a chance that the dead will be nine times out of ten! I'm still waiting for Aiqing to help me in the future, so please don't do this kind of dangerous thing! ”

Liu Haojia bowed down and said: "Thank you for your love, but this trip to Henan must go!" ”

Emperor Wanli said with some dissatisfaction: "Is there any reason why Liu Qing's family is so insistent?" ”

Liu Haojia said: "Long live you, you also know that Jinyiwei has raided many people's homes and accumulated a lot of things. Even in the storeroom, a lot of books have been saved. Some time ago, the minister was idle and had nothing to do, so he looked through these old books in the warehouse, and the minister found a way in these ancient books, saying that it could prevent smallpox! ”

Hearing this, Emperor Wanli stood up and said loudly: "Can you cure smallpox?" Is it true or fake? ”

Liu Haojia hurriedly said: "Long live Lord, the minister said that smallpox can be prevented, but he didn't say that smallpox can be cured!" ”

Liu Haojia saw that Emperor Wanli was still puzzled and said: "Long live the lord, smallpox is an incurable disease, which can only be prevented but not cured!" The person who has smallpox can only stand up, and all we can do is provide him with enough food and herbs to replenish his body. But according to the prescription in the book, maybe we can prevent it and prevent smallpox! ”

Emperor Wanli was interested now, and walked out from behind the bookcase and said, "Then the prescription didn't say how to do it?" ”

Liu Haojia said: "There is no specific practice, the above is just speculation that smallpox itself is too toxic, if the toxicity can be reduced, people are infected with low-toxicity smallpox, so that people can not die, but also let people get smallpox once, and then it will never be again." It's just that I don't know how to do it! ”

Emperor Wanli turned back to the chair and sat down, and said unhappily: "Isn't it the same as what you didn't say!" Everyone knows that smallpox will never be free after a pox, but who knows how to reduce the toxicity of smallpox! I thought it was a mature prescription, but I didn't expect it to be just an idea! ”

Liu Haojia said: "Long live the lord, but the minister thinks this idea is very reasonable, so he wants to verify it, and he already has a preliminary idea!" ”

Emperor Wanli said: "Then what are you going to do?" ”

Liu Haojia said: "The minister thought, since human pox can prevent smallpox, then one of the pox from livestock can also be used!" And the strongest of the livestock is probably the cow! They are strong, and they might survive smallpox! After such an experience, it is impossible to say that the toxicity of smallpox is weak, and it can completely prevent smallpox without killing people! ”

In fact, in the Ming Dynasty, with the development of medicine, people have found that infecting healthy people with the pox of patients can resist smallpox! But this kind of pox is still very toxic, and every time you plant pox, someone will die of illness! But even so, the pox epidemic prevention method was still promoted in the Ming Dynasty. And what Liu Haojia wants to do is to transform the human pox epidemic prevention method into the cowpox epidemic prevention method!

Emperor Wanli waved his hand and said impatiently: "This is nonsense, don't say it again!" You'd better stay in Jingshi and collect the money well! ”

Liu Haojia was a little helpless when he heard this! He knew that it would be difficult to convince Emperor Wanli, but he didn't think that he had no chance to persuade him! But at this time, Zhang Jia suddenly interjected and said, "Long live Lord, the slave maid thinks it's a good thing for Lord Liu to go out for a spin at this time!" ”

Emperor Wanli turned his head and said, "Why is this?" ”

Zhang Jia said: "Recently, the slaves and maids have received a lot of news, and the courtiers are very dissatisfied with Lord Liu! Especially the opinion of the imperial history is especially big! They are discussing the mistakes of Master Lee! ”

Recently, Zhang Jia has learned a lot from Liu Haojia, and he found that if he wants to make the right decision, without proper intelligence, he is simply messing around! So he tried to arrange a lot of eunuchs in the duty room. They don't really need to inquire about anything, just prick up their ears to pass on the useful news they hear when doing things, but he didn't expect it to make him a lot smarter.
