Since Jinyang is not in good health, Fang Jun sent her back to Fengyang Pavilion after staying in Fang Mansion for an hour.

When I came back, I found that a large number of soldiers were sent to the west of the city. I guess they were cleaning up something, and it seemed quite busy.

I don’t know what happened outside, but the residents of Chang’an City all seemed a little panicked.

Fang Jun thought about it and was too lazy to care about this matter. Anyway, he is not a doctor, so he doesn't know how to solve it?

They were rushing towards home, and suddenly they saw Fang Xuanling and Fang Yizhi and a group of people walking outside in a hurry, and they didn't know what they were going to do?

As soon as he saw Fang Jun, Fang Xuanling immediately shouted: "Jun'er, where are you going?"

Fang Jun hurriedly replied: "The child just sent Jinyang back to the palace. I wonder what my father has to give?"

Fang Xuanling frowned and was a little displeased: "There is no order. But in the past few days, don't go to the west of the city. Also, Princess Jinyang must not take it out of the palace at this time! Now Chang'an is an extraordinary period, and there is a violent aura in the west of the city. Your Majesty is summoning a group of doctors to treat it!"

Fang Jun frowned when he heard this: "Is the matter serious?"

"Seventeen or eighteen people have died. Do you think it's serious? Now Your Majesty has ordered strict defenses and defenses. No outsiders are allowed to enter Chang'an!" Fang Xuanling said: "Now Master Sun has also gone to Guzhou, which is said to have come from Guzhou. At this time, Chang'an is already panicked!"

Fang Jun thought for a while, nodded and said, "Yes!"

"Go back! If you have nothing to do these days, don't go out. Especially don't go to the west of the city!" Fang Xuanling continued, hurriedly walking outside, as if he was rushing to deal with it.

Fang Jun also returned home.

This day was relatively calm and nothing happened. Fang Jun was teasing the roe deer at home and doing nothing.

Since Jinyang has not been able to come out these days, it will be a little bored.

Fang Jun didn't care. Anyway, he just ate and drank and waited to die. He was bored, so he took chess and played chess with a few maids.

On this day, Fang Xuanling didn't come back until the evening. When he returned home, he immediately sighed and looked sad.

It is estimated that the epidemic cannot be lifted in a short period of time, and Chang'an seems to be even worse. It is said that three more people died...

Chang'an suddenly became a little nervous.

Early the next morning, Fang Xuanling went to the morning court as usual, but after returning, his face became more solemn.

A large group of people appeared on the streets of Chang'an. The person in charge of the leadership was Cheng Chubi. Fang Jun also walked out to take a look and many people were carried out.

The west of the city seems to be looking for a disease.

Fang Jun thought about it and found a good piece of silk cloth when he returned home, boiled it in boiling water and dried it, and made it into a mask and put it on his face.

It is a plague, which is the hostility mentioned in ancient books. It is very contagious and requires wearing a mask. Fang Jun is still quite afraid of death.

I don’t know what Sun Simiao is doing? Nowadays, no one outside seems to have a mask.

When Fang Xuanling and Fang Yizhi saw this, they couldn't help but be curious and asked, "Jun'er, what are you doing? Why are you covered with cloth on your face?"

Fang Jun was a little strange and said, "Didn't it mean that there is an epidemic in Chang'an? It's naturally to prevent epidemics!"

Fang Xuanling and Fang Yi were stunned.

Fang Jun said again: "Dad, brother, I have also said several masks, you can bring them with you too! It's safer if you go out!"

Fang Xuanling saw it and shook his head and said, "What's the use of doing this? Just make a fool of yourself! As Master Sun Simiao said, the epidemic is caused by typhoid fever, or there may be a rampant epidemic ghost. Now Your Majesty has ordered the people of Huasheng Temple to preside over the water and land conference to disperse the epidemic ghosts. Don't interfere in this matter!"

Fang Jun was stunned and said, "Your Majesty wants to preside over the water and land conference to disperse the epidemic ghosts?"

"That's true! There are many people in Chang'an now! Guzhou, Jingzhou, Xuzhou, Daizhou and Guozhou are even more serious. Your Majesty has been unable to wait and asks to preside over the water and land conference! Master Sun has also developed a new Tusu wine. It is said that drinking this wine will work!" Fang Xuanling said, looking at him again: "Anyway, if you don't go out in the past few days, don't go out! Stay at home obediently. In addition, don't take Princess Jinyang out of the palace!"

Fang Jun felt speechless, thought for a while, nodded and said, "Yes!"

Fang Xuanling didn't continue to say anything, and took Fang Yi straight out to deal with the problem.

They probably have to be busy again.

If Fang Jun is not there, he plans to go out of the city to see how the tiles fired by craftsmen? Chang'an has not been closed yet, so he can still go out.

Fang Jun found a horse with his mask and went out of the city directly.

When he came to the city gate, a team of people guarded here. Who else could the leader be Cheng Chubi?

Some soldiers were lifting some people out.

"Fang Er, what are you doing? Now you are leaving the city?" Cheng Chubi asked immediately as soon as he saw him.

Fang Jun nodded: "How about it outside the city now?"

"Not safe!" Cheng Chubi said: "Many refugees came from Guzhou and Xuzhou, etc., and they had gathered outside the city. Many doctors had rushed to treat them. The refugees coughed a lot, were out of breath, and had a fever all over, which was extremely serious."

Fang Jun took a look and found many camps outside, frowned: "It is said that His Majesty has presided over the water and land conference to expel the epidemic ghosts, is it still not good?"

"Okay, it will take a few days to talk about it! Now people in Xuzhou and Chang'an in Guzhou are in panic, and this epidemic is extraordinary!" Cheng Chubi said.

Fang Jun thought for a while, took out a mask and handed it to him and said, "That thing is covered on his face, maybe it may be of some use!"

Cheng Chubi was stunned and immediately laughed and said, "Fang Er, what is this? Why did you take out the little girl's handkerchief? Are you not afraid of laughing out loud?"

Fang Jun was amused and cried, and said, "What handkerchief? This is a mask, which can be used to prevent and treat this epidemic! This epidemic is caused by hostility. It is usually transmitted from the mouth and nose, or is transmitted from saliva. Covering the mouth and nose has a certain preventive and treatable effect!"

Cheng Chubi was stunned and widened his eyes slightly: "Are you serious?"

Fang Jun smiled and said, "What are you doing? It's just some use! The disease of warm and epidemics is not wind, cold, heat, or dampness, which is caused by a different kind of qi in the world. There are nine kinds of transmissions, which are the key links to treat epidemics. Covering the mouth and nose and not allowing the anger to enter the body, it will naturally have many uses!"

Cheng Chubi seemed stunned, and immediately felt a little unbelievable, and said with a smile: "Fang Er, what kind of epidemic do you know? Dao Zheng Sun Yaowang has never mentioned this. He just said that he could drink more Tu Su wine. How do you know that it was caused by the hostility? Your Majesty said that it was still a disaster in the Tang Dynasty!"

Fang Jun shook his head, but was too lazy to explain. Even in later generations, countless people suspected the function of the mask, let alone the ancient times?
