The smallpox plague was raging, spreading much faster than expected. On the fifth day of the first lunar month, it was reported that smallpox patients had appeared in Gaochun County, and the epidemic was rapidly advancing to Gaochun County.

It was only a matter of time before the county seat of Gaochun was conquered by the smallpox plague. The county government issued an emergency notice to implement a temporary control policy on the city gates, opening the doors for only one hour in the morning and evening every day, and closing the city gates for the rest of the time, strictly prohibiting people from entering at will.

On the sixth day of the first lunar month, a case of smallpox was detected in the county, which finally detonated the long-suppressed panic. There are all kinds of rumors in the county, most of the shops are closed, and the originally lively market is also sparsely trafficked.

Han Fei has been frowning and looking worried these days. The smallpox plague is spreading, and many innocent people are wrestling with death.

To be honest, for smallpox patients, Han Fei can't come up with an effective treatment plan, and the only thing he can do is prevention. He found that the most effective way to prevent smallpox virus is to vaccinate against cowpox, which can produce pathogenic antibodies. However, he has been keeping an eye on the mule and horse market these days, and has not found any infected cattle and no vaccinia vaccine, so he can only watch more people fall in front of the smallpox virus.

"Sister, Qin'er, I'm going to go out of the city......"

Before Han Fei's words were finished, Wang Ruolan and Xue Baoqin immediately pulled his arms tightly from left to right, and said in unison: "No! Now that the plague outside the city is so fierce, I heard that many people have died, how can you get out of the city? ”

Han Fei sighed and said, "Eldest sister, Qin'er, I understand your kindness, but I must go out of the city, otherwise even if I live in good health, I will not be at ease in this life!" ”

"What do you mean by that?"

"To tell you the truth, I have found a way to prevent the smallpox plague, but there is still one most important medicine missing, which has not been found in the city these days, and must go out of the city to find it! Nowadays, the smallpox plague is getting more and more ferocious, and more innocent people are dying every day, I ...... I can't sleep! ”

"Fei Di (Big Brother)-"

"Don't say it, I've made up my mind! You can rest assured, I am a doctor, I know how to protect myself, even if there is a ......" Han Fei looked at Wang Ruolan's bulging abdomen, and pretended to smile easily: "Anyway, the Han family already has a queen......"

"Big brother...... Xue Baoqin sobbed: "I want to go with you!" ”

"No, you have to stay and take care of the eldest sister!"

Han Fei glanced at Wang Ruolan, who was crying in a low voice, turned to Ling'er Qinglong and the other five children standing under the corridor and said, "Ling'er, Qinglong, White Tiger, Vermilion Bird, Xuanwu, are you afraid of death?" ”

"Don't be afraid!" The four of them, the Blue Dragon, the White Tiger, the Vermilion Bird, and the Xuanwu almost shouted in unison.

Han Fei nodded, looked at Ling'er who didn't answer, and said gently, "Why didn't Ling'er speak?" ”

Ling'er said very calmly: "The slave and maid are afraid of death, but as long as the young master has orders, the slave and maid will never back down even if they are crushed!" The young master is going out of the city today, and the slave and maid will definitely go out with him, unless the young master beats the slave and maid to death now! ”

Ling'er was young and spoke loudly, and everyone in the room was touched by her loyalty.

"You are all good, live up to Han's teaching, go change into tight clothes, bring protective equipment, let's go out of the city!"

Han Fei took Wuxiao out of the city when the city gate was opened in the morning, and rushed to the nearby village to look for sick cattle. When he left the city, he realized the horror of the smallpox plague even more, and they could not travel more than ten miles before they met several groups of people who had gone out of the funeral, and when they inquired, they all died of the plague. His heart was even heavier, and he had a strong sense of mission to fight against the smallpox virus.

Han Fei and the others ran all day, filled all the porcelain bottles they brought out, and then returned to the city when the city opened in the evening.

"Prepare torches and burn the coats of the six of us outside the door!"

Han Fei and Wuxiao took off their coats, threw them at the door, and washed them with light salt water before entering the house.

Xue Baoqin hugged a bunch of clothes, greeted him, and said, "Big brother, are you all right?" ”

"It's okay, this time I finally got cowpox, you gather everyone in the house to the front yard, and I will vaccinate you later!"

"Big brother, you've been busy for a day, don't worry about this, let's eat a good meal first! Oh, how many times have the magistrates sent people to discuss matters with you! ”

Han Fei understood that Zhixian Leng Feng must have come to him for the smallpox plague, and now that he had found the cowpox vaccine, his heart was naturally calm.

Just after eating, Menzi reported that Lord Leng of Zhixian County came over in person, and Han Fei hurriedly went out to greet him. He led the cold air directly to the study and pulled the servant back.

"My lord, Xiao Ke went out of the city to look for medicine to prevent and control the smallpox plague, and only came back for a while, and after preparing for dinner, I went to the county office to find you!"

"Doctor Han, this official has heard about it. Now that the plague is getting more and more fierce, the official's heart seems to be tormented, and he can't wait any longer in the county office, so he came to ask for an idea in person! Doctor Han, do you have anything to gain when you go out of the city today? ”

Han Fei looked at Leng Feng's hopeful eyes, and said with a faint smile: "Adults love the people like children, Xiao Ke admires, adults are at ease, Xiao Ke has found a way to deal with the symptoms, and the smallpox plague will definitely be contained!" ”

"That's good! That's good! Leng Feng looked relieved and asked, "Doctor Han, what kind of medicine can treat the smallpox plague?" ”

"This medicine does not cure the smallpox plague, it can only prevent it, that is, if you are vaccinated with this preventive measure, you will not be infected with the plague!" Han Fei sighed and said: "For patients who have been infected, they can only take conventional detoxification and anti-inflammatory treatment, and whether they can survive depends on the patient's physique!" ”

Leng Feng also sighed and said, "Even so, there will be countless lives!" Doctor Han, this official immediately went to the imperial court to buy your prescription to prevent the smallpox plague, and I hope that you will rescue first, so that more people will not die from the plague! ”

"My lord, no need!" Han Fei said solemnly: "The smallpox plague is a natural disaster, hundreds of thousands of people have suffered from this catastrophe, how can Xiao Ke make a fortune from the disaster? Adult, Xiao Ke is willing to donate prescriptions for free, and please call all Langzhong in the county, Xiao Ke teaches them overnight, and everyone works together to save more lives! ”

"Good! Good! Good! Doctor Han is really a Buddha of all families, and this official ......" Leng Feng was so excited that his hands trembled.

"The adult is too famous, but since the little one has learned medical skills, this is the mission!" Han Fei pondered for a moment, coughed, and said: "Adults treat Xiao Ke as amiable as a nephew, Xiao Ke just said a presumptuous word, this plague is terrible, but it is not an opportunity for adults, Xiao Ke dares to ask adults to personally rush to the treatment site tomorrow to calm the people's hearts!" ”

Leng Feng has been in the officialdom for a long time, so he is naturally not confused, and when he heard this, his eyes lit up, and Han Fei took a deep look and said: "Doctor Han, this official will personally invite all Lang Zhong to come over!" ”
