The matter is urgent, Li Xiu has just sent his family to Chang'an City, but he has to go out of the city again with Sun Simiao, Fang Xuanling's work efficiency is very high, and when Li Xiu and Sun Simiao go out of the city, he has already selected a place in the south of the city to test the effect of cowpox, which is located in a military camp in the south of the city, which is not very far from Qingtian County, where smallpox broke out, and there are several mountains in between.

When Li Xiu and Sun Simiao came to the barracks, Fang Xuanling had already sent over a cow that had just been found with cowpox, this was only the first one, there would definitely be more in the future, and there were ten death row prisoners, standing in a row on the school grounds.

"Pony, time is in a hurry, this cow was found by me from near Qingtian County, there is only this one for the time being, but I will definitely be able to find more in the future!" When Fang Xuanling saw Li Xiu coming, he stepped forward with a smile, he was also very curious about Li Xiu's method of planting cowpox, and this matter was very important, so he also came in person.

"Fang Xiang is polite, I thought I would have to wait for two days, but I didn't expect you to get things done in such a short time!" Li Xiu was very admiring at this time, Fang Xuanling deserved to be called a "virtuous face through the ages", and the efficiency of this method alone was not comparable to ordinary people.

"This time smallpox is menacing, although Your Majesty blocked the border of Qingtian County at the first time, but a county town is not small, and no one knows if there are people who have been in contact with the disease to leave Qingtian County beforehand, so now Your Majesty and I are very worried that smallpox will spread, so if we can confirm the effectiveness of this method of planting cowpox earlier, maybe we can save countless lives!"

When Fang Xuanling said at the end, he also showed a solemn expression on his face, if this method of planting cowpox was proven to be effective, then it would be another achievement that would be a great achievement, and it would be related to the lives of countless people, so he couldn't afford not to pay attention to it.

"Donkey, I think let's start now!" At this moment, I saw that Sun Simiao couldn't wait to speak, he trusted Li Xiu even more, especially after getting along this year, Li Xiu told him a lot of knowledge related to the human body and biology, which made Sun Simiao have a deeper understanding of medicine, and his medical skills were more refined before, so he was also eager to know what was the magic of this method of planting cowpox?

Seeing Sun Simiao's anxious appearance, Li Xiu couldn't help laughing, and then pulled Sun Simiao to the cow together, this is a cow, fat and strong, and the coat color is very bright, it doesn't look like a ploughing cow, in fact, this should be a cow, of course, it is not the black and white cow of later generations, but the grassland cow bought in the northern grassland.

The nobles of the Tang Dynasty like dairy products, and the most eaten are goat milk products, of course, there are some milk products, but the cattle are more expensive, and they are restricted by the imperial court, only a few nobles will raise some cattle in the courtyard outside the city for milk, for example, Li Xiu's family raised two cows that specialize in milk, mainly for Qi Niang and Mian Niang, these little girls to drink.

"Look, this cow has some pus-draining bumps, I wonder if it's the cowpox you're looking for?" Fang Xuanling also came over at this time and said, he didn't know what cowpox looked like, so he could only ask people to look for it according to Li Xiu's previous description.

Li Xiu actually didn't know cowpox, but he knew that cowpox was also caused by the smallpox virus, and since this cow was found from Qingtian County, where smallpox was found, there should be no mistake, but for the sake of insurance, Li Xiu still asked Sun Simiao next to him: "Sun Daochang, do you see that the pimple on this cow is the same as the pimple on the smallpox patient?" ”

Sun Simiao has rich experience in practicing medicine, in fact, he has encountered some smallpox patients before, so at this time, I saw him step forward and take a closer look, and sure enough, he found that there were many pimples on the lower abdomen of this cow, and some of them had even suppurated, looking a little disgusting.

"It's really similar to the pimple on the smallpox patient, is this cowpox?" Sun Simiao stroked his beard and observed for a moment, and finally nodded, and then asked Li Xiu, he didn't know what cowpox was, after all, he was not a veterinarian.

"That's right, this is cowpox!" Li Xiu also said very affirmatively when he heard Sun Simiao's answer. After saying that, he asked people to take a saucer and a knife, and then asked them to hold down the cow so as not to kick him, and then he stepped forward and picked out the pus from the cowpox with a knife and wiped it on the plate.

Although this cow is fat, but the cowpox on the body is limited, so in the end only a small amount of pus is collected, for these pus, can be directly applied to the human wound to plant pox, but this is a bit toxic, the safest way is to dry these pus, so that there will be a rough inactivation process of smallpox virus, so that its toxicity becomes smaller, and it is safer after planting pox.

But now Li Xiu doesn't have this time, so he took the plate and came directly to those death row prisoners, these death row prisoners are not stupid, just now I saw Li Xiu take something from the cow, and now he walked in front of him, which made them all instinctively feel a little frightened, even if there were soldiers around them, they all tried to shrink back as much as possible.

Li Xiu will not have any mercy for these death row prisoners, in fact, these death row prisoners almost do not have a good thing, either murderers or Jiangyang thieves, you can see one or two from their vicious faces alone.

So Li Xiu came directly to the first prisoner, the other party instinctively wanted to escape, but was held down by the soldiers, and as a result, he couldn't move at all, but in this way, it stimulated the ferocity of the other party, and he was about to scold when he opened his mouth, but he didn't expect that as soon as he scolded, he was kicked a few times in the stomach by the soldier next to him, and then the whole person immediately became honest.

Li Xiucai didn't know a death row prisoner, and after seeing that the other party didn't dare to resist anymore, he smiled last time, and directly used the knife just now to cut a small cross-shaped wound on the opponent's arm, and then wiped the pus on the wound, as a result, this originally fierce death row prisoner was so frightened that his whole body trembled, and he didn't dare to ask if he wanted to, let alone how pitiful it was.

"Don't worry, this thing won't kill you, but it will make you sick for a few days, and then you'll be fine!" Li Xiu explained lightly that he was afraid that if he didn't explain, he would scare these prisoners to death, or scare them into a mental breakdown.

In the end, Li Xiu planted cowpox on all ten death row prisoners, and there were still some leftover on the plate, but now this thing is a treasure, so he didn't waste it, let people take it to a clean place to dry, and then it can be used later.

"Colt, this ...... Is that all right? Seeing that Li Xiu was done, Fang Xuanling couldn't help but step forward and ask, although Li Xiu had already talked about the process of planting cowpox in the main hall before, he still felt that it was a little too simple, you must know that it was smallpox, known as one of the most terrible plagues, how could it be so simple to make people no longer infected with smallpox?

"Haha~, it's a big coincidence, the next thing is to wait for these prisoners to recover from their illness, and then you can contact them with smallpox patients, and then you can see the effect!" Seeing Fang Xuanling's somewhat skeptical expression, Li Xiu couldn't help laughing and said, it was really rare to be able to make Fang Xuanling, who had always been wise, show such an expression.

"Colt, will these prisoners become contagious when they become ill, or will they turn into smallpox when they become ill?" At this moment, Sun Simiao also stepped forward and asked, he had heard Li Xiu say before that the cause of this kind of cowpox was the same as smallpox, so he was worried about what unpredictable changes would happen to these prisoners after they became ill?

"This ...... It should not be contagious, although the cause of cowpox is the same as smallpox, but there are still some differences, but for the sake of insurance, it is better for these prisoners to be isolated and imprisoned, and wait until they are well! Li Xiu was also a little unsure, after all, he had never been vaccinated with cowpox in his previous life, but he had only seen the scars left by the acne on the arms of some elders.

"It's okay, since the symptoms of this cowpox are mild when they occur, you can also take a closer look at it at that time!" Sun Simiao nodded seriously when he heard this.

Hearing Li Xiu say this, Fang Xuanling immediately asked the prisoners to be imprisoned in a camp tent, and a fence was erected around them, and there were soldiers guarding them, except for Sun Simiao and Li Xiu, others were strictly forbidden to contact them.

In the next few days, Li Xiu also stayed in this barracks, mainly to observe the situation of those prisoners, and as a result, just a few days later, these ten prisoners also fell ill one after another, but what Li Xiu didn't expect was that the so-called onset symptoms were far milder than he imagined, and eight of the ten prisoners had no major symptoms, but some rash-like acne appeared around the wound, and then suppurated and scarred.

The remaining two have some small symptoms, one of them, a small rash all over the body, but it comes and goes quickly, and the other is more serious, and there is purpura all over the body, that is, purple marks, Sun Simiao explained that this is a kind of internal bleeding, and if it is not good, it may kill people, and the reason for this may be because this prisoner is relatively weak, after all, this guy has been in prison for a long time, and Li Xiu has also seen the environment in the cell, and if he lives there for a period of time, it is strange that his body is not weak.

However, purpura is only possible to kill, in fact its lethality rate is very low, and those on death row are generally hard, and finally the more serious prisoner has also recovered his health. However, this reminded Li Xiu that there is still a certain risk of planting cowpox, especially for the elderly, weak, women and children, and it is even more necessary to be cautious about planting cowpox.

Thinking of the above, Li Xiu couldn't help frowning, he is not a saint, one of the most important reasons why he offered this method of planting pox is for his wife and son, but now he sees that there is a risk of pox, even if the probability of risk is very small, he is reluctant to let his family take risks, especially since the two sons are still so young, and the probability of pox is also higher, what can I do?
