Chang'an City has been under martial law, and it is not allowed to enter or exit, but this ban is naturally invalid for Li Xiu, when He Panren took out Li Shimin's warrant, the guard of the city gate quickly opened the city gate, and then Li Xiu and his party entered the city, Princess Pingyang originally had her own princess mansion in Chang'an City, but she usually didn't like to live there, so the mansion has been empty, and there are usually special people to take care of it, so the mansion can live at any time.

Originally, He Panren also proposed to invite Li Xiu to live in their palace, which was also what Li Shimin had ordered him before, but Princess Pingyang did not agree, although the palace is safer, but the princess city in the city is also heavily guarded, not much worse than the palace, plus Princess Pingyang does not want to see Li Shimin at all, so she did not agree to this proposal.

However, Princess Pingyang did not enter the palace, but Li Xiu wanted to enter the palace to inquire about this smallpox, not to mention anything else, in case the epidemic of Tianhua was really uncontrollable, I am afraid that he and his family would be in danger, especially his two sons, after all, the plague does not matter what your identity is, whether it is a prince or a nobleman or a beggar on the street, the mortality rate after contracting the plague is about the same.

So after Li Xiu handed over the affairs of the family to Princess Pingyang and them, he immediately took Sun Simiao into the palace, and at this time the news of the smallpox outbreak had already spread, after all, the entire Chang'an City was already under martial law, if you sneeze on the street, Jin Wuwei would immediately take you away for quarantine, so such a big news could not be concealed at all.

However, this news also caused some confusion to Chang'an City, such as people rushing to buy food everywhere outside the grain store, and the price of grain in Chang'an is also rising three times a day, but even this still can't stop people's enthusiasm for buying, because everyone knows that if they don't buy it now, the price of food will only be higher in a few days.

Walking through the somewhat chaotic streets of Chang'an, Li Xiu's carriage finally came to the imperial city, and when he and Sun Simiao met Li Shimin, they found that he was discussing with several ministers, and these ministers were Li Xiu's acquaintances, namely the eldest grandson Wuji, Fang Xuanling, Du Ruhui and other old people from the original Tiance Mansion.

"Li Xiu, you and Sun Daochang came just in time, the smallpox epidemic is menacing, and Qingtian County is too close to Chang'an, I am worried that the epidemic will spread to Chang'an, you are all famous doctors in my Tang Dynasty, can there be a way to cure smallpox?" When Li Shimin saw Li Xiu and the others coming in, he immediately straightened up and asked, looking at them with a little hope in his eyes.

However, Li Xiu and Sun Simiao both looked at each other and smiled bitterly when they heard this, and finally Li Xiu stepped forward and confessed: "Your Majesty, there is no effective treatment for this stubborn disease of smallpox, and the minister and Sun Daochang are also helpless!" ”

Li Shimin couldn't help but show a disappointed expression when he heard Li Xiu's answer, in fact, he also knew that the possibility that Li Xiu and Sun Simiao could cure smallpox was very small, but in this situation, he could only give it a try with the mentality of just in case, but unfortunately Li Xiu's answer made his last glimmer of hope dashed.

"Your Majesty, although Poor Dao has no way to treat smallpox, as a doctor, he also wants to do his part, so Poor Dao wants to beg His Majesty to agree here to let Poor Dao go to the epidemic area to practice medicine!" I saw that Sun Simiao also stepped forward at this time and pleaded, in addition to doing his duty as a doctor, Sun Simiao also wanted to get close to smallpox, hoping to find a cure for this plague with his medical skills.

"This ......" Li Shimin also showed an embarrassed expression when he heard Sun Simiao's request, and only after a while did he speak, "Sun Daochang, the situation in the epidemic area is very bad, although smallpox has just been discovered, dozens of people have already fallen ill, and this smallpox epidemic is very serious, those cases have been sick and bedridden in just a few days, and almost all the people who have been in contact with them have also been infected, if you go now, I am afraid that you will also be infected!" ”

Smallpox is also severe, after some smallpox outbreaks, the patient's condition is mild, and maybe one in a hundred people will not die, but some smallpox epidemics are very serious, and even three or four people will die one, and this is still the data of later generations, in ancient times, the mortality rate will only be higher, and most of the survivors will have pockmarked faces.

"Thank you Your Majesty for your concern, but the poor Dao has made up his mind, and I ask Your Majesty for permission!" Sun Simiao had already made up his mind when he came, and naturally he would not give up because of Li Shimin's persuasion.

Seeing Sun Simiao's attitude so resolute, Li Shimin was also very embarrassed, and he also attached great importance to Sun Simiao's medical skills, especially his wife Empress Changsun's illness was cured by Sun Simiao, but Empress Changsun's illness is also related to congenital, and it may recur in the future, in addition, smallpox may spread to Chang'an City at any time, in case the people around him are infected with smallpox, they also need to be treated by famous doctors, even if there is no way to cure it, but they can always have a greater chance of survival.

It is precisely because of the above that Li Shimin was a little undecided for a while. But at this moment, I suddenly saw Li Xiu stand up and stop: "Daochang Sun, in fact, you don't have to rush to the epidemic area, because we have one more important thing to do!" ”

As soon as Li Xiu's words came out, not only Sun Simiao was a little surprised, but Li Shimin, eldest Sun Wuji and others also looked at him in surprise. However, Li Xiu was very calm at this time, and smiled again: "Your Majesty, Sun Daochang, once smallpox is infected, there is almost no effective treatment, but there is no way to treat it, it does not mean that there is no way to prevent it, it just so happens that I have a way to prevent smallpox!" ”

"What!" Hearing Li Xiu's words, Li Shimin, Eldest Sun Wuji and the others all looked at him in shock, and Sun Simiao rushed forward and grabbed his hand with an arrow, "Is this true?" ”

"Naturally it's true, I've been thinking about this matter on the road just now, but I can't do this matter on my own, I still need His Majesty's consent and support, as well as the help of Daochang Sun!" Li Xiu also smiled at this time, even if smallpox was almost extinct in later generations, its name was still active in various books, and in the previous life Li Xiu's previous generation, he had fought against smallpox, so he also knew the effective way to deal with smallpox.

"Great, Li Xiu, tell us quickly, is there any way to prevent smallpox?" Li Shimin also stepped forward excitedly at this time, after he learned that smallpox broke out near Chang'an last night, he discussed with the eldest grandson Wuji and them for half the night, but there was no other better way than to isolate as much as possible, which made his hair almost gray, and now Li Xiu finally let him see a glimmer of hope.

"This method is called planting cowpox, Sun Daochang must know that people who have smallpox will grow pox full of pus, and cattle will get similar diseases, and some poxes will grow on their bodies, this is cowpox, and the pus in cowpox is the material we need, when you use it, you can apply this pus to people's wounds, so that people will get cowpox, but the symptoms of this cowpox are mild, and people will not die, and after a few days of illness, this person will never be infected with smallpox again!" Li Xiu immediately explained the method of planting cowpox.

"This ...... Does this really work? As soon as Li Xiu's words fell, he saw the thin Du Ruhui stand up and say with some suspicion, he usually has little contact with Li Xiu, at most he is a nodding friend, although he has heard Li Shimin and Fang Xuanling praise Li Xiu, but he still has some doubts about Li Xiu's ability, especially this method of planting cowpox sounds really a bit mysterious, you must know that he is also a rough doctor, but he has never heard of such a treatment?

"Du Xiang's suspicion is understandable, in fact, I haven't tried this method myself, but we still have time, it just so happens that Sun Daochang is also here, we can find someone to try it!" Li Xiu was not annoyed by Du Ruhui's suspicions, although he knew that this method of planting cowpox would definitely work, but at least let Li Shimin and them see the effect.

"What the colt said is very true, I think it is better to let people find a few death row prisoners, plant them with cowpox, and then let them enter the epidemic area, and then we will know the effect!" Fang Xuanling agreed with Li Xiudao with a smile at this time.

"Good! Just do it, if you need anything Li Xiu, just say it, no matter how difficult it is, I will help you do it! Li Shimin said at this time, with his understanding of Li Xiu, as long as Li Xiu dared to say something, even if he was not ten percent sure, he would definitely be seven or eight percent sure, so he would say these words of unconditional support for Li Xiu.

"Thank you for Your Majesty's trust, the minister doesn't need much things, if you want to plant cowpox, you naturally have to take it from the cow that has cowpox, so the minister needs Your Majesty to find cowpox as much as possible, and even gather some healthy cattle, and then let them all be infected with cowpox, and then the master's hands take the pus from the cowpox, and there are a few death row prisoners to experiment, and nothing else." Li Xiu replied with a smile.

"No problem! Fang Xiang, this matter will be handed over to you to handle in person, and try to assist Li Xiu to implement this method of planting cowpox! Li Shimin agreed very happily at this time, and also sent his most powerful helper Fang Xuanling to Li Xiu, which shows that he attaches great importance to this matter.

Fang Xuanling also immediately agreed when he heard this, and then one after another decrees were issued from the imperial city, and the entire imperial court institutions near Chang'an were mobilized, all the cultivated cattle that could be found were requisitioned, and then concentrated in a military camp in the south of the city, and Li Xiu took advantage of this time to go home and explain to Princess Pingyang about the cowpox, and as a result, Princess Pingyang and Yi Niang were also very supportive of him, after all, if smallpox could be prevented, then they would not have to be so frightened as now.
