Liu Yingying put on the mask she had prepared beforehand, handed one to Xiaoxue, and was about to enter the patient's room.

The shopkeeper, unable to bear it any longer, kindly warned, "Miss, don't go in. That person has the plague and you'll catch it!"

"Don't worry, I'm a doctor too!"

After briefly identifying herself, she entered the room and saw a young man in his early twenties lying on the floor with a flushed face, his chest and limbs twitching from time to time.

Even from a distance, I could still see the red spots on his face and neck... This is...

At this moment, in addition to the shopkeeper and waiter, several other customers peeked out from the door.

Liu Yingying turned around and closed the door tightly before taking out gloves and goggles from her spatial storage and walking towards the person.

He drew a conclusion about the person's illness with almost just one glance.

——Smallpox!

This is what the ancients of this era called smallpox.

In later generations, people invented a vaccine specifically to suppress smallpox, thus eradicating the disease.

However, in ancient times, once this highly contagious disease spread, it was almost impossible to control.

Of those who survived, only one in ten remained!

Liu Yingying quickly used her consciousness to open the medical medicine section of the mall and carefully searched for medicines and vaccines that could be used to treat smallpox.

Finally, she found it when she turned to the last page.

Vaccine! 100 points per dose.

Without hesitation, she exchanged for a vaccine and injected it into the man's vein.

She fed him two more ibuprofen tablets before leaving the room, but she was slightly startled the moment she opened the door.

The officers and soldiers have arrived.

They held weapons at Liu Yingying to prevent her from coming out and spreading the disease to others.

"Young lady, you just had close contact with the patients inside. The authorities have ordered that all patients and those who have been in contact with them be taken away and quarantined!"

Liu Yingying frowned slightly. She could understand the government's reasons for doing this, but...

She cleared her throat and said, "It's like this, I'm a doctor, and the patients inside are improving after my treatment. They'll recover in less than seven days. If you take me away and isolate me as well, who will treat those patients?"

But the officers didn't believe her. They looked her up and down, their expressions contemptuous. "You and the patient inside are lovers, aren't you? Are you planning to abandon each other when disaster strikes?"

This situation has been quite common since the outbreak of hysteria.

How many couples, after one spouse contracts smallpox, are so eager for the other to sever ties...

Liu Yingying was a little angry at being misunderstood, but now was not the time to be angry.

She tried to explain further, but was immediately interrupted by the soldiers: "Alright, enough nonsense, hurry up and come with us to the quarantine point!"

As they were talking, two other people went inside, lifted the man on the ground onto a stretcher, and carried him outside.

Liu Yingying had no choice but to go with them.

As she went downstairs, she looked back and saw Xue Ye and Xiao Xue standing at the door, looking at her with worried expressions.

"Don't worry, I have a way to cure this plague! You all stay in the inn and take good care of yourselves, understand?" After saying that, he left without looking back.

"Brother Xue Ye, what do we do now?" Xiao Xue asked anxiously.

Xue Ye withdrew his concerned gaze from Liu Yingying's retreating figure, seemingly having made a decision in his heart, "Don't worry, I will bring her out safely!"

These words made Xiaoxue's heart skip a beat. She subconsciously wanted to grab his arm, but her hand hesitated and stopped in mid-air.

"Brother Xue Ye... what do you want to do?"

Xue Ye didn't speak. He had no interest in the commotion in the inn. He turned and went into his room, slamming the door shut.

Meanwhile, Liu Yingying followed the officials to the location in the city where patients were being isolated.

She had originally thought she would be taken to something like an abandoned city god temple, or a tent set up far from residential areas.

Unexpectedly, the so-called quarantine site occupied an entire empty mansion.

Judging from the architectural marks, this house must have been abandoned for quite some time. I wonder where the original owner went.

The huge mansion was divided into three areas.

The front yard was for patients with milder symptoms, while the middle yard was for patients with more severe symptoms. Each area was inhabited by men and women, and the sanitary conditions were extremely dirty and chaotic.

Imperial physicians would occasionally pass through the crowd, taking pulses and administering medicine to everyone…

Liu Yingying and the man were taken to the main hall of the central courtyard.

"Alright, you can stay here. The government will send you food every morning and evening."

Liu Yingying glanced at the dirty and messy ground under her feet, frowned deeply, and asked, "We're going to sleep here tonight, but how are we supposed to sleep here?"

Soldiers: In this situation, you should be grateful to have a place to shelter from the wind and rain. Are you being picky? Do you think you're some kind of prince or princess?

After saying that, she left, not bothering to argue with them.

Their location was drafty, with walls only on the left and right sides, allowing them to see plumes of black smoke rising directly into the sky above the backyard…

She couldn't help but ask the person next to her, "What's burning over there?"

The woman who answered her was covered in red pimples on her face and hands and looked very weak; "Don't worry, you'll be there in a few days!"

Hearing this, Liu Yingying immediately had a bad feeling. "You mean...they burned corpses there?"

The woman gave a cold, numb sneer: "What else? If so many people died and were all buried, it would pollute the water supply!"

These words made Liu Yingying's heart clench slightly.

She had only seen records of ancient plagues on television or in history books before, but none of them were as shocking as the experience of being there in person!

The government provided each patient with a straw mat, but fortunately, it was not yet autumn, so there was no need for blankets.

Liu Yingying carried her straw mat and found a slightly cleaner corner to sit down.

The imperial physician would come to inspect every hour, and also check on everyone's condition to see what stage it was at.

If a patient's condition becomes so severe that it is beyond repair, they will be taken directly to the backyard.

In this situation, it is very difficult for even one out of a hundred people to experience a change in symptoms from severe to mild.

Therefore, people were constantly being brought in from the front yard, but not a single person was seen leaving from there.

In an instant, panic spread among the people...

Liu Yingying, on the other hand, sat cross-legged with her eyes closed, leaning against the wall in thought.

Although she had vaccines that could restore these people to health, she came empty-handed.

If we were to simply produce a vaccine out of thin air and give it to everyone, not only would we not gain the public's trust, but we might also be treated like monsters and burned on the spot...

But if we keep waiting like this, the longer it drags on, the more people will die!

No, she can't waste any more time.

In the middle of the night, Liu Yingying was woken up from her sleep.
