Ten death row inmates were immediately forced to enter Qingtian County to contact the patient after being inoculated with cowpox, and the results showed excellent results, and after many days of contact with the patient, there was no sign of infection, and based on the onset of smallpox, it can almost be concluded that they all had antibodies on their bodies.

After proving the effect of cowpox, Li Shimin and others were also very excited, Fang Xuanling had collected a lot of cattle before, all of them were gathered together with cowpox, deliberately let them be infected with cowpox, and then took out pus as a material for pox.

The first batch of cowpox is Sun Simiao, these doctors, they are all doctors organized by Li Shimin, ready to enter Qingtian County to treat smallpox patients, in order to ensure their safety, so it is also necessary to plant cowpox, and these people after getting smallpox immunity, immediately began to enter Qingtian County, for people who have not yet had smallpox symptoms to vaccinate cowpox, in addition to the blockade of Qingtian County's army, they will also be vaccinated with cowpox.

Li Xiu thought that pox could only prevent smallpox, but Sun Simiao found in his observation that pox can actually treat smallpox, because after contracting smallpox, there will be an incubation period of 12 to 14 days, and the time to get immunity from vaccinia is just a little shorter than the incubation period of smallpox, so as long as the vaccination is timely, smallpox can actually be treated, which is a bit similar to the rabies vaccine in later generations, but the incubation period of rabies is longer.

In addition, there is another thing worth being happy about, that is, smallpox was successfully confined to Qingtian County, although some suspected smallpox patients were found around, but they were later found to be misdiagnosed, which also made the entire Tang Dynasty breathe a sigh of relief, and then Li Shimin publicized the method of planting cowpox, in order to calm people's hearts, and by the way, Li Xiu's name was famous all over the world again, but Li Xiu has never cared much about this kind of thing.

Seeing that everything was on the right track, Li Xiu also missed his wife and son at home, so he said to Fang Xuanling and went back to the city, Fang Xuanling also knew that Li Xiu's identity was special, and even Li Shimin would not force him to do anything, unless he agreed, so Fang Xuanling also agreed immediately, and then sent someone to send Li Xiu back to Chang'an City.

Princess Pingyang's mansion is located in the southeast corner of Chang'an City, not very far from Qujiang Pond, and now this is also Li Xiu's home, when he returned home, Princess Pingyang and Yi Niang also came to greet him, but he didn't bring the child, after all, in this case, the child still tried to go out as little as possible, especially Li Xiu just came back from outside the city, and it was so close to Qingtian County, so they were also very careful.

Li Xiu was also anxious to see his son, and immediately bathed and changed clothes after returning home with his wife, and then entered the inner house, but when the two little guys saw him, they were a little stunned, the older Ping An Lang was okay, and he recognized him after looking at him for a while, and opened his fat little hand to let Li Xiu hug him, but Jin'er, who was only half a year old, looked at Li Xiu with wide eyes for a while, and did not let Li Xiu hug him, and he had not seen him for a month, and he forgot about Li Xiu's father.

However, the child has no memory, and he forgets it quickly, and he remembers it quickly, Li Xiu also has enough patience, and after holding Ping'an Lang and Jin'er for a while, the two little guys will no longer recognize their lives, especially when Li Xiu and the two little guys play the game of throwing sticks, as a result, the two little guys climbed fast on the carpet, and the crisp laughter kept ringing, but unfortunately it didn't take long to play, Li Xiu was carried out of the room by Princess Pingyang and Yi Niang with one ear, in their words: I have never seen such a bad father for his son!

After lunch, Li Xiu took out a porcelain bottle, and then solemnly said to Princess Pingyang and Yi Niang: "Lady, this is the cowpox powder I collected, as long as you plant this, you will never be afraid of smallpox in the future!" ”

Although it is convenient to use cowpox pus directly, it is too toxic, and the cowpox pus that has just been taken out may also contain other germs, so now cowpox is used to dry cowpox powder.

"Great, during your absence, the name of cowpox has spread all over Chang'an, and now everyone is praising Fujun's merits, but I heard that the production of this cowpox powder is limited, and many princes and nobles are willing to pay thousands of dollars to buy it, but no one sells it at all!" Yi Niang's eyes lit up when she saw the porcelain bottle in Li Xiu's hand, she was thinking that if she could produce cowpox powder at home, it would be a profitable business.

"Hehe, it's hard for others to find money, it's not difficult for me to come, although this bottle is not much, but it is enough for our family, as well as some close people, ladies and sisters, you discuss it, see who needs to plant pox, and then gather people, especially the people who usually come into contact with our son, but also all of them must be planted with cowpox!" When Li Xiu said the end, he also showed a solemn expression on his face, this bottle of cowpox powder was kept by him privately, in order to plant it for his family first.

"What my husband said is very true, the sooner you plant cowpox, you can feel at ease early, I'll go and let someone arrange it!" Princess Pingyang also nodded in agreement when she heard this.

Although Li Xiu's approach is a bit selfish, but the method of planting cowpox was originally thought up by Li Xiu, if Li Xiu's heart is a little darker, he does not offer this method, but secretly produces cowpox powder by himself, and then sells it as a medicine, it is definitely a million profits, but Li Xiu did not plant it like this, now take a little home and use it for his family first, even if the world knows about it, he will not say anything.

Immediately afterwards, Princess Pingyang called Yuechan, and then discussed the list of the first batch of vaccinators with Yi Niang, and then Yuechan went out to gather people, and Li Xiu took out a small box at this time, and after opening it, there were several special knives inside, and there was also a porcelain bottle with the label of "alcohol", this is the alcohol that Li Xiu made before, subject to grain production, the output of alcohol has not been high, and can only be supplied to the army.

"Lady, you roll up your sleeves, I'll help you get the first pox!" Li Xiu smiled at this time and picked up a knife in the box, and then disinfected it with alcohol.

"Husband, have you planted it?" What Li Xiu didn't expect was that Princess Pingyang and Yi Niang almost agreed to ask with concern, and then the two also looked at each other a little embarrassed, but they both laughed out loud.

"Don't worry, I've had cowpox before I came, and it's already scarred now!" Li Xiu smiled at this time and rolled up his sleeves, only to see that there was a blood scab the size of a soybean on his right arm.

Originally, Li Xiu should have been vaccinated with Sun Simiao and them, but there was too little cowpox powder at that time, so he gave the opportunity to a soldier who escorted the doctor, after all, with the outbreak of smallpox, Qingtian County was also in chaos, and I heard that even the county order died under smallpox, so Sun Simiao They also need the protection of the soldiers, and one more person will be safer.

"Husband, will this pox affect feeding the child, now Ping An Lang and Jin Er are still breastfeeding?" But at this time, Yi Niang suddenly said a little worried, they are still breastfeeding, although there are nurses, but they usually feed their children personally, because in the eyes of mothers in this era, only children are fed by themselves, and they will be closer to themselves in the future.

"This ......" Li Xiu was also stunned when he heard this, and when he thought about it for a while, he immediately thought of a way and said, "This is easy to do, don't feed the children after you have planted cowpox, anyway, there are nurses at home, as for the nurses, let them plant pox after a while!" ”

"It's still Sister Yi Niang and her husband who are thoughtful, let's give me pox first, Sister Yi Niang is weaker, so it's good to be mentally prepared." When Princess Pingyang heard this, she first praised Yi Niang and Li Xiu, and then offered to be the first to accept the pox Dao, she was not fighting for anything, but it was the first time for her and Yi Niang to plant pox, and it was inevitable that they were a little nervous.

"It's the same for everyone first, but since my sister takes care of me so much, then my sister is better to obey her fate than to be respectful!" Yi Niang also smiled when she heard this, and then stood aside to watch Li Xiu give Princess Pingyang pox.

There is really no technical content in planting pox, when he planted pox for Sun Simiao and others, Li Xiu had already practiced it, and he was also familiar with the road at this time, and soon helped Princess Pingyang plant cowpox, but Yi Niang saw that she had to cut a wound when she planted pox, and she was also a little scared in her heart, but thinking of the horror of smallpox, she finally closed her eyes and asked Li Xiu to help her plant cowpox.

At this time, Yuechan also gathered the first batch of people in the family to plant pox, most of them were close to the people in the inner house, and Li Xiu also helped them plant pox one by one, but Princess Pingyang and their estimation was wrong, and when these people were planted with cowpox, there was still a little cowpox powder left in the porcelain bottle that had not been used up.

"There is still a little bit left, why don't you go into the palace tomorrow to help your father get cowpox!" Seeing this, Princess Pingyang opened her mouth and proposed, she has always taken her father under house arrest in Da'an Palace to heart, and she will think of Li Yuan in everything.

"No, when the cowpox powder was just made, His Majesty asked people to plant it for the Emperor." Li Xiu said with a smile, all the cowpox powder in and out of the previous had to pass through his hands, so he knew better than anyone where these things were going, and although Li Shimin put Li Yuan under house arrest, he didn't want people to say that he was unfilial, so as long as Li Yuan didn't fight for power with him, he would be extremely filial.

The lady next to her heard Li Xiu's conversation with Princess Pingyang, and her heart was also soft, but when she thought of her father, she still couldn't help but feel angry, and finally didn't speak, but Li Xiu smiled when she saw her appearance, the remaining cowpox powder in the porcelain bottle was enough for two or three people to use, and it was nothing to plant Pei Ju in advance, and he also thought of a person, this person should need cowpox powder more than others.
