The house was confiscated at the beginning, so I evacuated my enemy's house to escape.

Fu Yanci lowered his head as he was told and let Feng Jiuyan do whatever she wanted.

"Okay, you must wear a mask when you go out, and you can't take it off."

"Mask?" Fu Yanci asked in confusion. He had never seen or heard of this thing before.

"What's the use of this?"

"Hehe, of course it is useful. Wearing a mask can provide some protection, so you won't be easily infected with the disease." Feng Jiuyan explained.

At the end of the world, doctors and experts found that the virus was transmitted through droplets. Therefore, Feng Jiuyan combined the symptoms of the patients infected with the virus at the end of the world with the symptoms of the patients infected with the epidemic in Youzhou City, and she guessed that the epidemic in Youzhou City was likely transmitted through droplets.

Fu Yanci raised his hand to touch the mask, but was stopped by Feng Jiuyan. "Ah Ci, you can't touch the outer layer of the mask. It may be contaminated with the virus. If you are curious about it, I will give you a new research later."

"Okay." Fu Yanci's eyes were full of smiles.

Feng Jiuyan took out another blue mask from her cross-body bag, demonstrated in front of Fu Yanci how to wear it, and taught him how to take off the mask correctly.

After she put on the mask, she looked at Xing'er and said, "Xing'er, just send her here. It's better not to leave the house. It's dangerous outside."

Xing Er bowed, "Okay, Miss, Your Majesty, I will wait for you in the yard."

"Yeah, okay." Feng Jiuyan took the bag.

After Feng Jiuyan got on the car, she also gave the driver a mask and taught him how to wear it.

After the two got on the carriage, Feng Jiuyan untied the bag, revealing a whole bag of masks inside.

She looked at Fu Yanci and said, "Give these masks to the doctors, patrolling soldiers, and those who help isolate the patients. If you don't have enough, tell me, I have more."

"That's great. Xiaojiu, you just solved a big worry for me." Fu Yanci held Feng Jiuyan's little hand tightly, his face full of excitement.

He has been worried these days that the soldiers and other civilians who were not infected might infect more people by coming into contact with patients while helping to isolate patients or patrolling the streets.

Now, with the mask given by Feng Jiuyan, the risk of infection can be greatly reduced.

The two of them soon arrived at the isolation shed. Feng Jiuyan walked around inside and found that the isolation shed in front of her was very well made. Although it looked a little shabby, there were no major problems. After she mentioned a few areas that needed improvement, she and Fu Yanci left.

By this time, it was already evening and night had fallen.

The two of them were riding in a carriage on their way back to the small courtyard.

"Aci, can you get the wild animals sold by King Qi's people? I can use them." Feng Jiuyan said.

There is a medical space in her space, which is equipped with complete medical equipment. If she gets wild animals, she can use modern medical instruments to further determine whether the virus is transmitted through droplets, and she can also find a prescription after conducting experiments.

Fu Yanci pondered for a while before saying, "It should be possible to get it."

"Well, I'll wait for your good news. This is related to the speed of finding the prescription." Feng Jiuyan said.

As soon as the two returned to the yard, dinner was prepared.

She and Fu Yanci were the only ones having dinner in the front hall. Xing'er wanted to wait on the side, but Feng Jiuyan asked her to leave and go have her own dinner.

The two men ate and chatted, and the content of the conversation was either about the solution to the epidemic or about the developments in the capital.

After they finished dinner, Fu Yanci went to deal with official business, and she returned to the main room.

She had just finished bathing with Xing'er's help when Fu Yanci's men came into her yard holding a wooden box.

Xing'er left the yard and brought the wooden box into the room. "Miss, this was sent by the prince. He said it contains what you want."

Feng Jiuyan took the wooden box and brought it into the room.

Just as Xing'er was about to follow in, Feng Jiuyan turned around and said to her, "Xing'er, I want to study the source of the disease, which is extremely dangerous. I don't like people being around because it will distract me. Go back to your room and rest. I'll come find you when I need you."

When Xing Er heard that it would affect Feng Jiuyan's research on the epidemic, she hurriedly stopped and nodded quickly, "Miss, just keep busy. I will never disturb you."

After saying that, she lifted her skirt and trotted out of the main room. During this time, she did not forget to help Feng Jiuyan close the door tightly.

Feng Jiuyan put the wooden box into the space, walked to the door and bolted it. After making sure that the door and windows were tightly closed, she flashed into the space.

Perhaps Fu Yanci had sent the secret guards out to do something, so there were no secret guards hiding in the dark in this small courtyard. This made it convenient for Feng Jiuyan to enter the space at will.

After Feng Jiuyan entered the space, he went straight to the medical space.

After she changed her clothes and put on gloves, she used her mind to control the wooden box and brought it into the medical space.

......

Feng Jiuyan stayed in the space for more than ten hours. After more than ten hours of research, Feng Jiuyan determined that the source of the epidemic was indeed caused by the wild animals sold by King Qi's people.

These wild animals sold to various places were all carrying viruses. She didn't know why the King of Qi did this.

Moreover, through this experimental research, Feng Jiuyan has been very sure that the epidemic is transmitted through droplets.

As for the treatment prescription, it will have to wait until she comes into contact with the patient before it can be determined.

Feng Jiuyan came out of the medical space, stretched his body, and breathed a sigh of relief. Although the treatment prescription has not yet been determined, there are some gains this time.

She was not in a hurry to leave the space, but went straight to the bathroom and took a nice flower petal bath. There were not many days left for her to take a break, so she had to cherish these few moments of leisure.

After taking a bath, she went into the kitchen and selected some snacks she liked. After filling her stomach, she came out of the space.

This time, she stayed in the space for about twenty hours, but in reality, only about twenty minutes had passed.

Feng Jiuyan took out the wooden box from the space. The wild boar meat in the box had been disposed of by her, and inside was a similar piece of ordinary wild boar meat that did not carry the virus.

She held the wooden box and handed it back to Fu Yanci's men, asking them to dig a hole and bury it.

She went to Fu Yanci's study and informed him of the results of her research in detail.

Fu Yanci suddenly slammed his palm hard on the desk, making a dull and loud thumping sound. His whole body exuded an extremely strong and chilling chill, as if the air around him was frozen. He gritted his teeth and said, "The King of Qi is a wicked and ambitious bastard. In order to ascend to the throne, he used all means and disregarded the lives of others. He deserves to die!"
