Chinese are undoubtedly the smartest in the world, they created the human pox technique to save countless people who may be infected with smallpox and died, and later the British borrowed the art of human pox, found a way to plant cowpox to completely eliminate the smallpox virus, but the source of pox used by the ancient Chinese people is the human pox that poses a greater threat to humans, so after the pox, there will be a small number of people's own immune system can not resist the spread of the virus, and the outbreak will be either dead or disabled, with a certain danger.

Duan Fei was fearless, because he didn't plan to plant human pox on himself at all, he had already ordered someone to look for pox cows, most of the antigens of cowpox virus and smallpox virus are the same, and they will not cause disease to the human body, and there is absolutely no danger of planting cowpox.

But now of course Duan Fei will not tell Yang Yiqing that they have a foolproof plan, after listening to Yang Yiqing's words, he still pretended to be surprised and showed a look of hesitation, Yang Yiqing saw this and thought that he was willing to go to Shaanxi just to get the news of the epidemic in advance, and when he turned over the book, he felt that this was a good opportunity to make meritorious contributions, so he rushed to Shaanxi.

After Yang Yi cleared Duan Fei's good dreams, he explained to him in detail some methods to prevent and control the epidemic, in Duan Fei's opinion, these methods have a certain degree of advancement, but they are not on point, no wonder smallpox is so difficult to prevent.

Yang Yiqing asked Duan Fei to bury the body as soon as possible after burning the body, which is right, what other methods such as dredging are used to prevent dysentery, cholera or something is okay, smallpox is transmitted through oral foam and direct contact, wear a mask, try to keep a distance from the patient, it is not easy to be infected, if you really have to contact the patient, wear gloves and protective clothing, and clean yourself and your clothes and utensils frequently.

However, Duan Fei still listened to Yang Yiqing's words very carefully, Qian Rujing also listened very carefully, Wang Shouren was very knowledgeable, had a wide range of knowledge, and was also very good at studying medical skills, he interjected a sentence or two from time to time, which was very reasonable, and Duan Fei was awe-inspiringly taught.

Yang Yiqing said for a long time, and when he couldn't say anything new, he sighed lightly and said: "I hope this disaster will end as soon as possible, Da Ming can't afford to toss like this, Lord Duan, no matter what your and I political opinions are, please do your best to prevent the spread of the disease, otherwise the consequences will be unimaginable!" ”

Duan Fei swore and said: "Lord Yang, please rest assured, Duan Fei will not dare to miss the major national affairs, if he does not succeed in this trip, he will become benevolent, if he misses the major events, the emperor will not kill me, and Duan Fei will not dare to live in this world anymore." ”

Hearing Duan Fei's words, several Shangshu sighed lightly, but why they sighed were in different moods.

In addition to Qian Rujing, the four Shangshu encouraged Duan Fei one after another, and then left, only Qian Rujing stayed worriedly, he wanted to discuss it with Duan Fei.

After everyone else left, Qian Rujing said: "Lord Duan, I really can't imagine that the situation in the DPRK and China is so bad, and even a famous minister like Yang Yiqing is so short-sighted, and when he finds an opportunity, he will attack his political enemies, and he will say it in a high-sounding manner, but I am afraid that I can't wait for us to go back forever." ”

Duan Fei sighed and said, "We have a clear conscience, no matter how he tosses, you won't be afraid, Lord Qian, right?" It is indeed dangerous to go to Shaanxi here, if Lord Qian does not want to go, I can ask the emperor to appoint another adult to accompany me. ”

Qian Rujing said with a smile: "It's a blessing or a curse, it's a disaster that can't be avoided, since I have nodded in front of the emperor, how can I regret it?" Lord Duan, don't underestimate me too much, my Qian Rujing is not as afraid of death as Fei Hong, Lord Duan, we will leave tomorrow, let's discuss how to arrange the itinerary. ”

Duan Fei said: "I have already planned the trip, Lord Qian will see if there are any omissions?" I plan to enter Shanxi by Bauhinia Pass from Fangshan, and then go straight to Taiyuan, Xi'an, ......"

……

After sending Qian Rujing away, Duan Fei returned to the backyard, Guan Xiaohan walked up to him and said with a smile: "Childe, I heard...... Are you looking for me? ”

Duan Fei nodded and said, "You come with me." ”

The two came to Duan Fei's study, and Duan Fei asked, "You should already know about the affairs in Shanxi, right?" ”

Guan Xiaohan nodded and said, "I just found out. ”

Duan Fei's face sank and asked, "Did the Demon Sect do it?" ”

Guan Xiaohan shook his head and said: "Ah Fei, I don't know about this matter, the Divine Sect in Shaanxi has been repeatedly purged, and I don't have the ability to stretch my hand that far, but the sect leader may start again in Shaanxi, but what's the use of hurting others and benefiting oneself?" ”

Duan Fei snorted and said, "Are you really ignorant or false?" ”

Guan Xiaohan hesitated for a moment, and finally said: "Ah Fei, I only know that the sect leader has appeared in Xi'an, and I don't know anything about the rest, I have been busy in the capital these days, and you also know some things, even if it is really the sect leader who did it, it has nothing to do with me, I will never do such a hurtful thing." ”

Seeing her pouting pitifully, Duan Fei's heart couldn't help but soften, and said, "I know it has nothing to do with you, alas, do you want me to send someone to help?" Jingshi is the territory of Duomiao Immortal Gu, and it is not easy for you to take over her power completely, right? ”

Guan Xiaohan smiled: "It's not difficult, you have already helped me a lot, but don't think about snatching all the divine and religious forces of the entire Jingshi so easily, if your subordinate goes too far, be careful that I expose his true identity, and it will be difficult to clean up the mess by then." ”

Duan Fei laughed dryly and said, "I'm going to Shanxi tomorrow morning, what are you going to arrange?" Come with me? Princess, how do you explain it? ”

Guan Xiaohan said: "Princess, you don't need to explain anything, follow you to send your news back at any time and tell her, it is all the tasks she gave me, but this time I can't always follow you, it's more convenient for me to act alone." ”

Duan Fei nodded and said, "I was about to tell you that this time I have ordered that you are not allowed to bring your female dependents, you hide aside, contact me at any time, be careful." ”

Guan Xiaohan nodded, and Duan Fei asked again: "Acne is epidemic in Shaanxi, do you have a way to protect yourself?" Don't come back as marijuana flowers, I'll be distressed. ”

Guan Xiaohan smiled: "I'm worried about you, we all had human pox when we were young, and it will be fine, but you, why did you accidentally take on such a task, do you know what it means to be seeded?" This kind of folk method, I am afraid that the imperial doctor only knows its name and does not know the truth, and if you try it in vain, it will kill many people. ”

Pox is indeed a science, if you plant less, the human body will not produce immunity, and if you plant more, you will really get smallpox, there is already technology in the Demon Sect that can control the mortality rate to a very low level, Guan Xiaohan planned to offer a treasure to Duan Fei, but he didn't expect Duan Fei to just smile slightly, walked past Guan Xiaohan, took down a copy of "Analects" on the shelf, flipped through it casually, and then handed it to Guan Xiaohan.

Guan Xiaohan took it strangely, and saw what was in the book, the pages were full of small characters written neatly from left to right with a quill pen, and the four slightly larger first words of the human pox technique quickly attracted Guan Xiaohan's attention, she looked carefully, but it was a detailed and detailed pox planting technique, in which the dosage, time limit, and methods supplemented by herbs to enhance the body's resistance were very detailed and specific, more detailed than Guan Xiaohan knew.

"This ...... Who are you? Guan Xiaohan held the "Analects" of selling dog meat with a sheep's head, and his eyes swept quickly over the shelves full of four books and five classics, and then fell on Duan Fei's face again.

Duan Fei smiled and said, "Didn't you already guess a few points in your heart?" I remember that you once asked me what kind of divine skill I practiced, and I was able to completely restrain your Xuanyin divine skill. ”

Guan Xiaohan was shocked and smiled happily: "It turns out that you are really a disciple of the Divine Sect, what is your identity in the Divine Sect?" I'm the Holy Maiden of the Rizong Sect, why don't you come forward and pay a visit? ”

Duan Fei smiled slightly, and said indifferently: "The little saintess also dares to show off her power in front of the deity, I am the sect master of the Divine Sect, and it is you who should come forward to meet you!" ”

Guan Xiaohan's eyes were shining, she cheered, flashed and swept towards the bookshelf, Duan Fei didn't stop her, I saw Guan Xiaohan take out a copy of "Historical Records" from the bookshelf, opened it and hurriedly swept it, and suddenly let out another cheer, she excitedly put the book away, took out another copy of "Warring States Policy" and flipped through it, and couldn't help but let out another cheer, like a child who got a big cart of candy, so excited that it was hard to control herself.
