South of Chang'an City.

On both sides of the official road, a group of people were fetching water and making fires to cook.

Most of these people are refugees, and they are affected by disasters and fled. They will enter Chang'an City during the day to find some work, and go out to spend the night at night. Many people gather in this area.

With a land temple as the center, roughly more than 20 thatched huts or tents were built. Some hungry and yellow-faced people were cooking fires. The food was all the disaster relief grains of Wannian County. The number of refugees coming to Chang'an every year is quite large. Wannian County has its own processing process. If there are not many people, it will arrange for the yamen runners to identify their identities and move back to their hometowns.

Compared with previous years, refugees who came to Chang'an City this year have been much better, and the granaries in Wannian County are almost unable to accumulate, so the food is distributed very sufficient. A large part of the reason why these people look hungry and malnutrition is caused by long journeys and malnutrition, but they can only do this. People leave their hometowns and have stuttering. This group of people are already very satisfied. If they were not forced to leave their hometowns, who would have to leave their hometowns.

Chen Qingzhi came to this area with his men, not armor, but masks and gloves tightly, and could become a refugee area. Seeing these strangely dressed in clothes approaching, he was instinctively scared. Some left-behind people stood up one after another, their eyes full of alert.

"Dr. Qian, where is the family you mentioned?"

The doctor named Qian Zhong walked out, glanced carefully, and pointed to a child of a few years not far away: "It was that child who pulled me, it should be his family!"

Chen Qingzhi nodded, walked down from his horse and towards the child. At this time, a woman stopped Chen Qingzhi, said something loudly, and knelt down to kowtow to Chen Qingzhi. Chen Qingzhi didn't understand and looked at the follower beside him: "What did she say?"

"General, she said that the child was just stunned and ran into the doctor, asking you not to catch the child!"

The entourage was from Shannan and could understand the woman's words. After hearing this, Chen Qingzhi looked at the entourage: "Tell her that she is not here to catch her child, but to verify the situation!"

"Here!"

Soon, Chen Qingzhi led the child and the woman to his house, and saw a middle-aged man lying on the bed in a simple wooden house.

"Smallopsis is really smallpox, really smallpox!"

After seeing this, Doctor Qian confirmed that this was smallpox at a glance and immediately screamed in horror.

When people heard the frightened screams of Mr. Qian, the people around him became nervous. Smallpox, a disease of this disease, have all heard of it. Now some people have smallpox and some are ready to run away.

"Stop them, no one is allowed to move around, stay at home, Zhou Sui!"

"exist!"

"Notify Wannian County and ask them to send people here quickly, so there must be no differences here, and immediately investigate when these people have entered Chang'an City recently and who have contacted!"

"Here!"

In the East Palace, Yu Zhiqian was waiting anxiously. The memorial had been written. As long as the south side of the city could be confirmed to be the epidemic in Shannan Road, Yu Zhiqian would report it immediately. The epidemic in Shannan Road might not be able to control it and he had been concealing it.

"Your Highness the Crown Prince!"

A yamen runner trotted into the East Palace. After seeing this, Yu Zhiqian raised his eyebrows: "What's the matter!"

"General Chen Qingzhi and General Chen asked the villain to report to His Royal Highness the Prince. He has confirmed that the family in the south of the city is indeed smallpox and has fled from Shannan Road!"

After hearing this, Yu Zhigan immediately stood up from his position: "Where is Chen Qingzhi?"

"Your Highness, General Chen said that he has been in contact with smallpox patients and should not enter the Eastern Palace and let the villain report!"

"Okay, I understand, Chen Wansan, I want to enter the palace and change my clothes. Go and tell Chen Qingzhi and immediately block the scene. No one is allowed to enter and exit, and no one is allowed to approach the three miles around. Let him wait, and I will go there later!" After saying that, Yu Zhigan quickly changed his clothes and rushed to the palace. He had already made the worst plan in his heart. There might be a big problem in Shannan Road.

In ancient times, the medical conditions were very poor. The outbreak of plagues could easily cause a large number of deaths. The consequences of a plague were unestimated. Yu Zhigan was very worried that the entire Shannan Road would be infected now.

However, it is not all bad news. The good news is that traffic was very underdeveloped in ancient times and there was little movement of people. A plague broke out in a region and rarely caused large-scale infection. However, if it was infected by animals, the consequences may be unimaginable. Yu Zhigan didn't know how smallpox spread, but now he can only prevent the occurrence of a larger epidemic as much as possible.

"The prince is here?"

The emperor was having a meal and was not right. After hearing that Yu Zhigan had arrived, he immediately put down his bowls and chopsticks and looked at Yu Zhigan.

"Father, the epidemic in Shannan Road is probably not as simple as the report of the Shannan Governor. People who fled from Shannan Road have appeared in the south of Chang'an City. They have been confirmed to be suffering from smallpox!"

"What?"

The emperor was also shocked and took Yu Zhigan's memorial: "Have you investigated?"

Yu Zhigan nodded vigorously: "Someone has been sent to investigate. Chen Qingzhi has arrived in the south of the city and blocked the refugee location. However, something big might happen to Shannan Road!"

The emperor narrowed his eyes and stood up from the dining table: "I already know this. There must be no plague in Chang'an City. Have you heard of it?"

"My son understands that, but Father, Mr. Mr. need to mobilize some supplies urgently, and he also needs to send someone to search in Chang'an City. You need your token!"

The emperor handed over a large seal: "As for the matter urgently, you can kill me first and then report!"

"My son obeys the order!"

Yu Zhigan took the token, but didn't even look at it. He turned around and was about to leave. Suddenly he thought of something: "Father, my son-in-law thinks that those who enter and leave the palace now must also be disinfected, especially those who leave the comprador. The palace must also be disinfected. In some places where people often enter and exit, it is best to have stricter control!"

The emperor nodded: "I understand!"

The emperor did not think Yu Zhi was making a big fuss. Smallpox was really terrible. The emperor liked to study historical materials and had seen things that caused dynasty turmoil due to the plague, so he was very cautious.

After Yu Zhigan left the palace, he immediately returned to the East Palace and asked Chen Wansan to bring some of his own clothes and essentials to change his clothes, and prepare not to live in the East Palace during this period, otherwise he would have contacted too many people, if he was infected with Cheng Xiang and others...

After Yu Zhigan changed his clothes in the south of the city, he walked in. After seeing Yu Zhigan, Chen Qingzhi immediately stopped Yu Zhigan: "Your Highness, why are you here? This is dangerous. You should wait outside!"

Yu Zhigan glanced at the refugee area in the distance: "How is the situation investigation? How about the Shannan Road?"

"I've asked, they are from Jiangcheng, Shannandao. There are rumors of smallpox in Jiangcheng in March this year. About a month ago, someone in their village was infected, so they escaped and ran out of Jiangcheng overnight!"

"Why do you have to stay overnight?"

"In order to prevent the epidemic from spreading, the officials in Jiangcheng will not let the people go out. If they don't run away overnight, they will not be able to leave!"

Yu Zhigan nodded. In terms of controlling the epidemic, the officials in Jiangcheng did the right thing: "It should be quarantined, so why do they run away?"

"Your Highness, if you don't run away, you will starve to death. Their village has been sealed off and you are not allowed to enter and exit. After eating the food at home, many people in the village have died of illness..."

“Didn’t anyone send food?”

"No, they said that more people died in Jiangcheng. When they ran away, some of the yamen runners who blocked the village were infected, so they were able to run out!"

"So serious?"

"They ran out all the way, and many villages on Shannan Road were empty, and many people died!"

"Damn it, have they entered the city and contacted anyone after they came to Chang'an City?"

"Your Highness, I have asked. After their family came to Chang'an City, they had not been to Chang'an City for the time being because they were sick. The only people they came into contact with were yamen runners who came to distribute relief food!"

"Did you ask who it is?"

"Your Highness, you are Liu Rui and Zhang Quanming's yamen runners from Wannian County!" A yamen runner from Wannian County said in a low voice.

"Has found it?"

"Liu Rui and Zhang Quan have been unwell for three days and have not paid the price!"

After hearing this, Yu Zhigan's heart lit up. After hearing this family came to Chang'an City, they had not entered the city. Yu Zhigan was still happy, but now it seems that he is thinking too much. Two people named Liu Rui and Zhang Quan must have been infected.

"Send someone to check the situation at their homes immediately. If the infection is confirmed, immediately put the next door to his house, and then check the people who have recently contacted his home. You must be careful. You can also go to the Ministry of Works and the Ministry of Revenue to urge more quicklime to prepare and prepare for a major cleaning in Chang'an City!"

"Here!"

After Yu Zhi finished his work, he quickly returned to a garden in Chang'an City. Yu Zhi Gan didn't dare to go back in the East Palace, for fear of infecting Cheng Xiang and others. After all, Cheng Xiang was born in half a month.

"Your Highness, the sick cow has been found!"

As soon as he entered the villa, Yu Zhigan heard good news. After hearing this, he was overjoyed and found the sick cow. The following test was about the conditions in ancient times. There was no condition for you to develop. Just start the human test. Cowpox can only be prevented and cannot be cured. This is enough, at least it can block the infection of smallpox.

As for treating smallpox, Yu Zhigan never thought about this. Smallpox has not been eliminated in later generations, let alone the current medical conditions. As long as the cowpox can be proved to be useful, vaccinated with people with cowpox and vaccinated from generation to generation, smallpox will be completely eliminated. As for the people in Shannandao, how much can they be saved.

"Is this cow?"

He nodded on Wednesday: "Your Highness is this cow, look here!"

After saying that, he pointed to the position in the middle of the bull's retreat: "It's here!"

After Yu Zhigan carefully observed, he did develop some acne in the middle of the cow's legs, near some undescribable positions.

"Well, there should be nothing wrong!"

Yu Zhigan narrowed his eyes and observed carefully for a while, and then confirmed that it should be correct: "Li Sheng, take people to Dali Temple or Chang'an County, Wannian County Prison, and find some death row prisoners!"

"Here!"

Chang'an City was moving very quickly, and Liu Rui and Zhang Quan were found soon. Without any surprise, the two were also infected with smallpox. However, the good news is that both of them were single dogs and had no family members. They only went to the clinic in the past two days without too much contact. However, even so, the residence was blocked and quickly lime was disinfected to ensure that it would not be infected.

About an hour later, eight death row prisoners were taken to the villa. All of these eight death row prisoners committed death row crimes. Some were strong and some were relatively thin. Yu Zhigan did not ask them what crimes they had committed. He glanced at them and said slowly, "Do you want to live?"

The prisoners looked at each other, but didn't know how to reply for a while, so they could only lower their heads and not speak.

"Now there is a chance before you, which can exempt you from the death penalty! Of course, death penalty can be avoided, but the crime of living cannot be escaped, so it will be replaced by exile for thousands of miles!"

At this time, a burly prisoner looked at Yu Zhigan: "Who are you? Can we save us from the death penalty? Humph! I heard that the emperor is an old man, what is you, a young boy!"

"presumptuous!"

Several yamen runners rushed over immediately to beat this arrogant guy. After hearing this, Yu Zhigan couldn't help but be stunned for a moment, and then smiled: "I am the prince of the current dynasty. Do you think I can forgive you for your death penalty? I can save Zhang Xiaojing's unforgivable sins!"

Hearing Yu Zhigan's words, the death row prisoner's eyes lit up, and then lowered his head and stopped talking.

"But I just inform you that it doesn't matter whether you agree or not, it's just to prepare you. Qian Zhong, come here and prepare them for vaccination!"

"Here!"

Soon a soldier tied up eight death row prisoners, and then led the cow over on Wednesday. Yu Zhigan looked at them, held the cow down, and asked Wednesday to carefully cut the cow into it. The pus inside immediately broke. He took a small container and carefully collected more than a dozen cow into it. He collected a little cow into it.

"First cut the arm they mentioned, don't be too wide, and then apply the liquid!"

"Here!"

The eight prisoners watched the whole process, not knowing what the prince was going to do, and they struggled hard, but there was no effect. The soldiers held them tightly and prevented them from moving.

"Don't move around, otherwise the wound will be a little big!" Qian Zhong walked carefully to the first prisoner with a knife.

"Use fire to disinfect it!" Yu Zhigan reminded him.

"Here!"

Soon, after disinfecting, he took a knife and cut a bloody mouth on the arm of the first prisoner. The blood immediately overflowed, and then quickly took something like a cotton swab and dripped the cowpox pus on the wound.

"What is this? What is this?"
