An Yingcheng agreed to his daughter's request and immediately ordered the guards to call doctor over.

The white bearded doctor followed behind the guards and panted. Before she could stand still at her original spot, An Lingge had already opened her mouth, "A servant girl in my courtyard suddenly died, her symptoms looked like she had a plague. Please follow me to take a look."

The word pestilence caused doctor's expression to freeze, and her heavy breathing also stopped.

"What did you say, Miss? Plague?"

There was surprise and suspicion on his face, his thin eyes were full of seriousness, "The plague only happens once in a hundred years. Even if the plague breaks out, it won't start from here."

When the Great Zhou Dynasty was first founded, it had caused a plague. The rich and powerful Jiangnan was struck by the plague overnight. From the village to the city, it was filled with rotting corpses.

That plague had caused the late emperor, who had just ascended to the throne, to be questioned by the people. He believed that the late emperor had acted unjustly and had killed too heavily, so the people of the land had sent down a punishment as a warning.

Seeing how the plague was spreading and how tens of thousands of citizens were being tortured to death by it, the memorials fell onto the late emperor's study like snowflakes falling from the sky. The late emperor was furious and killed several officials who were going to deal with the plague, but in the end, he was still unable to withstand the pressure. Under the persuasion of the ministers, he wrote a crime edict and then ordered people of Imperial Hospital to go to Jiangnan to treat the plague.

It had only been twenty or thirty years, how could there be another plague?

An Lingge knew that the doctor did not believe her words, just like how An Yingcheng did not believe her. However, she had her memories of her previous life, so she knew that the plague would definitely break out in the capital.

"I know that it is a little ridiculous to say that, but the matter of the plague is extremely important, so doctor will follow me to take a look. If that servant girl only died from an ordinary illness, take it that I did not say anything today, but if that servant girl was really affected by the plague, then we should have made preparations in advance."

The doctor looked at An Yingcheng with an inquiring gaze, and received a permission from An Yingcheng, "Since Little Ge said so, you should follow her over to take a look."

After waiting for doctor to come to a conclusion, Little Ge would know that she was being overly cautious. This was not bad, or perhaps it was not good, but he needed to use this chance to teach Little Ge.

With this thought, An Yingcheng seemed to already know the conclusion of the doctor.

doctor agreed and followed An Lingge out.

Fortunately, the woodshed was not too far away from An Yingcheng's study. doctor took a deep breath and walked forward as if she was resigned to her fate.

The woodshed was just a little remote and needed to take several small paths, but it didn't take long.

An Lingge saw Bi Zhu standing in front of the woodshed's door. She held a bucket of tung oil and threw it towards the woodshed's door with all her might.

There was still time!

An Lingge immediately ran over with her skirt raised, her expression somewhat anxious.

"Miss, you're back."

Bi Zhu put down the tung oil in her hands, and quickly walked over, "What does Your Highness say, do you want to order the burning of the woodshed?"

"Father did not say, he did not believe that Lan Xin was infected by the plague." An Lingge shook her head, she then turned and looked at doctor behind him, "But I had father invite doctor over, and had him look over Lan Xin's symptoms. If Lan Xin was really infected with the plague, I will report it to father."

While she was speaking, the doctor finally caught up.

He stretched out his hand to wipe the sweat on his forehead and asked anxiously, "Young Miss, where is the maidservant?"

Bi Zhu pointed towards the tightly shut woodshed.

The doctor pushed the door open without a word, and a cold and rotten smell immediately filled him to the point of coughing.

An Lingge brought Bi Zhu and followed behind doctor, watching as doctor crouched down and examined Lan Xin's body from head to toe.

In a short moment, the doctor frowned, "Young miss, other than a sudden death, does this servant have any other symptoms?"

At this time, Ming Xin walked in, "We have already checked earlier, there are many red pimples below Lan Xin's neck, and there are also many large chunks of broken skin."

Seeing that she had returned, An Lingge knew that she had already dispersed the servants and guards around so that no one could barge in.

Hearing her words, doctor's expression suddenly became serious.

He stroked his grizzled beard and frowned. "That shouldn't be the case."

As if she had some unanswered questions, doctor crouched down again. This time he pulled up a corner of Lan Xin's collar, and the red viciously jumped into her eyes.

"It's the plague!"

doctor exclaimed in a low voice. She subconsciously took a step back, and fell onto the ground.

A look of truth flashed past An Lingge's eyes, and her expression was as serious as the doctor's. "A plague has appeared in my residence, this matter cannot be underestimated. I'll go report it to father now, I hope that doctor can accompany me."

After the doctor panicked, she realized that she had lost her composure. His old face flushed, and upon hearing An Lingge's words, she immediately stood up, patted off the dust on her body and said seriously, "It's all thanks to First Miss for being sharp, otherwise, when the plague spread, the entire Duke Palace would have been in deep trouble."

It was not only the Palace. In his previous life, everyone in the capital was terrified by the plague. How many people had died in this plague?

An Lingge did not reply, she only brought doctor out, and the clear voice floated around the woodshed, "Find someone to burn this place down, do not burn anything else."

He needed to find guards to prevent himself from getting into trouble.

After she understood what An Lingge meant, she agreed and left with Bi Zhu.

An Yingcheng was sitting in the study room, waiting for doctor to come over to report on the results, when he saw An Lingge walking in with a serious expression.

When this expression fell in front of An Yingcheng's eyes, it caused him to be shocked in his heart.

doctor quickly walked in front of An Yingcheng and explained the results, "From the condition of the servant, she might have contracted the plague."

He had already been a doctor in the Prince's Mansion for dozens of years. Although his medical skills were not as good as that of the imperial physicians in the palace, he was still much stronger than ordinary doctors.

Now that doctor had said such words, no matter how unwilling An Yingcheng was to believe it, she had no choice but to take this matter seriously.

With his hands behind his back, Fang Zheng's face was serious.

"Then what should we do with the maidservants?"

"Daughter has told the people around us to burn the woodshed to prevent it from spreading to other people." An Lingge lowered her eyes, and spoke with an unhurried and unhurried pace.

Her punishment was very appropriate, so An Yingcheng acknowledged, with an unexplainable expression in his eyes.
