"Cowpox, wonderful! The old man never thought of replacing human pox with cowpox. Sun Simiao suddenly realized.

"Old immortals, angry and stupid, does this cowpox have anything to do with the smallpox epidemic?"

"This old man knows a little, but this little friend should know better than the old man, so let the little friend explain it to you." Sun Simiao said with a talking smile.

"Cowpox is a disease that occurs in cattle, mainly near the milk, when the herdsmen on the grassland milk the cows, because they come into contact with the cowpox on the side of the milk, the hands are easily infected, there will be water bags, suppuration, epidermal ulceration, and finally the scab falls off and heals naturally, but it will also leave white spots on the hands.

But people infected with cowpox are generally not fatal, but there will also be people with weak resistance, and when the disease is serious, there is also the possibility of fatality, but in this case, it is difficult to have one in 1,000 people, compared to smallpox infected by humans, it is much safer.

Moreover, people who have been infected with cowpox will produce an antibody in their body, and they will never be infected with cowpox again in the future, and they will not be infected with smallpox. ”

Although they are not veterinarians who treat cattle, they still know and have seen cowpox on some cows, but they have not linked cowpox with smallpox in people at all.

"Although I don't know what the outcome will be? But what Xiao Langjun said is very reasonable and worth a try. Sun Simiao said.

"Need to find some death row inmates to try? King Gu then ordered that all the death row prisoners in the entire territory of Yizhou be gathered and taken to the prison in Yizhou City. When the King of Shu saw the result, he hurriedly said happily.

Everyone looked at Li Zhonghua, after all, he came up with this method.

"In fact, there is no need for this, it is not a secret, I have already done experiments, and there is basically no problem in terms of safety, and the key now is to control the epidemic as soon as possible.

If you are not at ease, then find a few prisoners to try, but the time will be delayed for another month or two. ”

In order to control the spread of the epidemic as soon as possible, Li Zhonghua had to tell a white lie, but the prevention of smallpox virus infection by planting cowpox has been widely confirmed in later generations, and all mankind has completely eradicated the smallpox disease and made it extinct.

Despite this, everyone insisted on seeing the effect before promoting it.

"His Royal Highness the King of Shu, the methods to prevent the smallpox epidemic have been explained clearly, and there are still things to do in the future, so I will leave."

Li Zhonghua thought in his heart, the specific things to be operated later, what these imperial doctors want to do, it has nothing to do with him, as for the reward mentioned in the medical order, it is estimated that it will not be so fast, and he still thinks about the important matter of visiting the church and getting married.

"How can you go? Before the smallpox epidemic is completely controlled, you will temporarily live in the Pontus Governor's Mansion, come here, arrange a courtyard for the little divine doctor, and send someone to serve the little divine doctor, and you must not be rude to the little divine doctor. Li Ke, the king of Shu, hurriedly said.

"His Royal Highness the King of Shu, I brought my subordinates to Yizhou City to do business, and those people are still waiting in the inn." Li Zhonghua said embarrassedly.

"Just send someone to inform them, let them go back on their own after they finish things."

"Lao Tzu is still going to prepare to worship and get married." Li Zhonghua thought sadly and indignantly in his heart, whether he dared to say anything more, it was better not to be too public.

In the Chang'an Imperial Palace in the capital, the government hall.

Empress Changsun was lying on the bed, wheezing and coughing sounded from time to time, the left-behind imperial doctor was diagnosing for her, and Taizong Li Shimin was eagerly walking back and forth in front of the bed.

"Imperial Doctor Wu, how is the queen's condition?" Seeing that the imperial doctor stood up, Li Shimin asked in a deep voice.

"The minister is incompetent, and the queen's mother is weak because she is infected with the wind and cold, which induces the old disease ......."

"Don't talk nonsense with me, I just want to know when my queen will recover." Li Shimin said very angrily.

"The minister is incompetent, and the queen's illness can only be slowly recuperated, and after her qi and blood are full, she will ...... Just now...... There is a hope for healing...... Wish. Imperial Physician Wu was sweating on his head, trembling with fright, and even speaking became unreliable.

Accompanying the king is like accompanying the tiger, working as a doctor in the palace, which seems to be infinitely beautiful, but it is also a high-risk profession, and it may die at any time.

"You quack, what's the use of me leaving you, someone ...... come."

"Ahem...... Your Majesty...... Ahem, cough, cough ....... ”

"Guanyin, how are you? Isn't it uncomfortable? Li Shimin hurriedly ran to Empress Changsun's bed, grabbed one of Empress Changsun's hands, helped her to sit up, leaned on his arms and gently stroked Empress Changsun's chest and asked.

The eldest grandson queen, who finally coughed smoothly, leaned on Li Shimin's arms, showing a happy and satisfied smile.

"Your Majesty, don't blame Imperial Doctor Wu anymore, the concubine's illness, even the old gods can't think of a cure, is Your Majesty going to be ready to kill all the doctors in the world?"

Li Shimin knew very well that what Empress Changsun said was reasonable, just now he was on fire for a while, and he almost killed Imperial Doctor Wu and almost became a tyrant.

After calming down, he glanced at Imperial Physician Wu, who was pale and kneeling on the side, and said, "Queen Rende, thank the Queen Mother for saving her life." ”

"Thank you, Your Majesty, and thank you to the Queen Mother for saving your life."

"Stand down!"

……

"Your Majesty, you are the king of a country, how can you be righteous and angry, your temper should really be changed."

"I listen to you, as long as your body gets better soon, I will listen to you for everything."

Tai Chi Palace.

Li Shimin was reviewing the recital on the dragon case.

He picked up the urgent report sent by Li Ke, the king of Shu, from Yizhou, opened it and started it.

The general content of the recital is that the smallpox epidemic in Yizhou has been basically controlled, and it emphasizes that Li Zhonghua's cowpox planting method presented to the imperial court has a miraculous effect on controlling the epidemic, as long as the person who has cowpox will no longer be in danger of contracting smallpox.

Finally, it attached a detailed and specific steps and methods for planting cowpox, as well as precautions, and asked my father to issue an order as soon as possible to promote it throughout the Tang Dynasty and benefit the people of the world.

Not only that, but the old immortal, Sun Simiao, was also mentioned in the recital.

"Come on, draft the will, Xuan Lao Immortal Sun Simiao quickly entered Beijing." Li Shimin put down the music and ordered loudly excitedly.

The smallpox epidemic in Yizhou has been controlled, which is of course a great joy, but getting the news of the old fairy Sun Simiao is the happiest thing for Li Shimin, he believes that as long as the old fairy enters the palace, his eldest grandson Empress will be saved.
