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

After Feng Jiuyan finished speaking in one breath, she looked at Fu Yanci with her eyes wide open, "Someone tampered with the medicine!" She exclaimed in a low voice.

"The medicine is effective for the symptoms, but it doesn't have much effect on the patient. It's obvious that someone has tampered with the medicine! It seems that King Qi's men have not been captured yet." Fu Yanci said.

"Just as I thought. After dinner, I'll go to the medicine cooking room in the isolation shed to find out what's going on!"

"I'll let Bai Li accompany you. I'm worried about you going alone." Fu Yanci said.

Facing Fu Yanci's worried eyes, Feng Jiuyan smiled. "Okay, I'll listen to you."

After Feng Jiuyan and the others finished their meal, Fu Yanci called Bai Li over and said with a very serious look, "Bai Li, you should know that the patients in Pingyao City have not gotten better after taking the medicine for a few days. Xiao Jiu and I believe that the King of Qi's men have not been arrested yet, and the spies are still lurking in Pingyao City. This matter must be related to the spies.

I can't go out these days, so you can go with Xiaojiu for a while. You must do your best to protect her and never let her get hurt."

Bai Li nodded and replied solemnly, "Yes, Your Majesty. I will keep it in mind."

Feng Jiuyan and Bai Li were fully armed and protected. Bai Li helped her carry the heavy medicine box, and the two went out together.

She was treating patients as usual, and no one could tell anything was wrong.

Bai Li always stayed within one meter of Feng Jiuyan, pretending to be busy with the things at hand, but in fact he was observing the people in the isolation shed, trying to find the spy.

Feng Jiuyan was busy until it was time to boil the herbs. She took Bai Li into the medicine shed.

At this time, there were eight people in the medicine room as usual. Among them, there were four young men, two of whom were servants of the county magistrate of Pingyao City, and the other two were citizens of Pingyao City who volunteered to help. These four young men were responsible for carrying water and boiling medicine, mainly doing some heavy work.

Among the other four people, there were two girls and two women, all of whom were servants in the county magistrate's household.

Feng Jiuyan stepped into the medicine-boiling shed. The eight people who were busy boiling medicine or fetching water stopped what they were doing and greeted Feng Jiuyan respectfully.

"Hello, Miss Feng."

The eight of them all recognized Feng Jiuyan, and they also knew that the prescription for treating the epidemic was prescribed by Feng Jiuyan, so they were all very respectful to her.

Feng Jiuyan waved and said with a smile, "Hehe, hello."

One of the taller young men smiled innocently and said, "Miss Feng, why are you here? It's so hot here, it's really not suitable for you to stay here."

"Haha, it's okay. I'm used to making soup and medicine. I came here to take a look."

"Oh, that's how it is. Hehe." The tall boy scratched his head and smiled foolishly.

"What stage have we reached now?" Feng Jiuyan asked.

"To answer Miss Feng's question, the herbs were just applied not long ago." The middle-aged man, who looked rather sturdy, said with a smile.

Feng Jiuyan nodded, then she picked up a wooden stick that was specially used to stir the herbs in the pot. She stirred the pot for a while and found that all the herbs in the pot were as she provided. There was no missing herb, and no strange things were added.

Other than that, based on her estimation of the weight of the herbs from the pot, there wasn't anything wrong.

Feng Jiuyan came here to inspect without notifying anyone. Therefore, this shows that there is no problem with the process of boiling the herbs.

It would be impossible to distribute the medicine in front of so many people. Then, the bad guys could only do it during the time when they were carrying the medicine out.

The eight people in charge of boiling the medicinal soup looked at Feng Jiuyan in confusion. She glanced at their facial expressions but did not speak.

Then, she continued to stir the other pots of boiling medicine with the stick in her hand. She shook her head and nodded, observing the expressions of the eight people from the corner of her eyes. She found that two of them looked a little strange.

They seemed somewhat pleased with themselves, and at the same time their eyes seemed to be mixed with some sarcasm and contempt.

These two people were the tall man and the sturdy middle-aged man who actively responded to Feng Jiuyan's words at the beginning.

Feng Jiuyan did not say anything, but continued to check the herbs in the pot. After checking all the pots in the medicine shed, he walked back to the eight people.

She glanced at a few people, smiled, and said casually, "Oh, I want to see how the medicine you boiled is. It turns out that your skills are good, and the soup is very good, hehe."

After receiving Feng Jiuyan's praise, the people present couldn't help but laugh. It seemed that they were very happy to receive Feng Jiuyan's praise. Only those two people seemed to be laughing, but their eyes were still mixed with a trace of contempt and disdain.

Feng Jiuyan did not say anything, but pretended to be curious and asked a few more questions.

"Who is usually responsible for lighting the fire?"

"Miss Feng, it's me, along with Xiao Cui, Xiao Hong, and Aunt Zhang." The speaker was a girl with a round face that looked like an apple.

Feng Jiuyan praised and gave the four of them a thumbs up, "You are really amazing. The most important thing in boiling medicine is to control the heat. You deserve half the credit for the medicine being boiled so well."

After she asked this question, she glanced at the tall and sturdy middle-aged man out of the corner of her eye. It was obvious that the two of them were becoming visibly tense.

The smile on Feng Jiuyan's face became warmer. "Okay, I won't keep you any longer. Just make the soup and I'll have your county magistrate reward you."

"Thank you, Miss Feng." Several people's faces were filled with smiles, and they were even more motivated.

"Bai Li, let's go."

"Yes, Miss Feng."

Feng Jiuyan and Bai Li left the medicine shed together. After walking a long distance, Bai Li looked around and made sure that there was no one around. Then he whispered to Feng Jiuyan, "Miss Feng, do you think that tall young man and that sturdy middle-aged man are suspicious?"

She nodded, a hint of coldness flashing in her eyes, "These two people are indeed very suspicious. Judging from their body shapes, they should be mainly responsible for carrying the medicine out. They must have made some moves along the way. You keep an eye on these two people later. If they show any signs of being caught, arrest them immediately!"
