The strange thing is that this drug is highly addictive. A small amount of it will not kill people, but will make them addicted.

The person who takes the medicine will decay and die without anyone noticing.

Lu Yanluo was surprised. Isn't this similar to modern medicine? Could it really be a medicine?

Modern poisons are too heavily refined and can be fatal if taken in overdose. The ones here may just be simple drug extracts, which can kill people if not handled properly.

Having some doubts in her mind, Lu Yanluo immediately discussed with Chu Xuan and investigated the matter thoroughly.

If this medicine really comes from Beiliang, it means that someone in Tianji is privately selling this medicine.

Chu Xuan knew something about this drug called Mu Si. It was said that this drug was extracted from a plant unique to Beiliang. It was extremely harmful and its sale was banned in Beiliang.

Unexpectedly, this thing appeared in the capital without anyone noticing. Chu Xuan looked solemn. He called Shen He and ordered, "Immediately check whether the officials and wealthy merchants in the capital have had private contact with people from Beiliang. This includes the cargo ships that have been transported from Beiliang to the capital in recent days, etc., and they should be thoroughly checked."

This matter is of great importance and no mistakes can be made.

Shen He took the order and left, and returned home with the news the next day.

In the study of Ye'an Mansion.

Chu Xuan and Lu Yanluo listened to Shen He's report in silence, secretly surprised.

Unexpectedly, the illness of Steward Li's mother led to a major case. If you didn't investigate it, you wouldn't know it. After investigating it, you found out that many officials in the capital were involved in this case.

"Minister of Revenue Pei Tianqi, Envoy of the Imperial Court Wang He, Junior Secretary of the Imperial Household Li Shou, and Deputy Secretary of the Supreme Court Yan Shaobai, all of these people have secretly bought a batch of goods from Beiliang through the wealthy merchant Jia Jing. Most of the goods are rare treasures, but there is only one very secret box. So far, no one except those people knows what is inside."

"I suspect that these people's purchase of rare treasures through Jia Jing is fake, and their main purpose is to smuggle contraband from Beiliang."

"Private goods? Could it be Mu Si!" Lu Yanluo stood up excitedly: "Although these people are not the great Yuan in the court, they are at least the heads of various departments. In this way, this matter may involve a lot of people."

Chu Xuan's face was gloomy, and there was already anger in his eyes: "How audacious! As an official appointed by the court, he actually sold banned drugs for profit. It's simply hateful! Keep investigating. Find the evidence and see how I will deal with them!"

Speaking of evidence, Lu Yanluo already has a plan.

"In two days, the Minister of Industry will hold a full-moon banquet for his grandson. These people will definitely be there. I will find an opportunity to talk to their families and see if there will be any clues."

A few days later, Lu Yanluo personally went to the Minister of Works' grandson's house with gifts to attend the full moon banquet.

At the banquet, she paid special attention to the families of the officials on Shen He's list. Several people were gathered together chatting, and Lu Yanluo pretended to be bored and walked over leisurely. Seeing this, several people immediately stopped talking, stood up and bowed respectfully.

"No need to be so polite, everyone." Lu Yanluo smiled kindly, very approachable: "It's really boring over there, I saw you guys were having a good time chatting, so I came over to join in the fun, come and sit down, don't be so polite."

Several women also smiled when they saw this. Among them, Bai, the wife of the Yuanwailang of the Ministry of Revenue, was the most straightforward, while the others looked cautious.

For a moment, Lu Yanluo had an estimate in her heart, and lowered her eyes, making it impossible for people to see her intention: "Speaking of which, I heard an interesting thing recently. It is said that there is a medicine in our capital that can make people happy and beautiful like gods. Do you know what medicine it is?"

When they heard this, their expressions changed, but they all avoided looking. This made Lu Yanluo even more certain that the box that Shen He found that day contained Mu Si.

"Why do you suddenly ask this, Princess?"

Bai was a man of outspokenness who could not keep secrets, so he asked immediately.

Lu Yanluo smiled, showing a curious look: "Of course I want to give it a try. People say that being a god is great. Since I have the chance, I might as well experience what it feels like to be a god."

Bai understood, and without waiting for others to speak, she waved her hand and said regretfully: "I didn't expect that the princess would be so interested in this thing. If I had known, I would have left some for you. Now they have all been sold, and there is no more in our house."

"Mrs. Pei! Be careful with your words!" The other ladies hurriedly stopped Mrs. Bai from continuing.

Lu Yanluo seemed to have seen through everything. She raised her hand to signal them to stay calm and said soothingly, "Don't panic, everyone. I'm just curious about this thing and want to buy some to try. I don't have any other intentions. Don't be afraid."

It was also because Lu Yanluo had a bewitching face that the people present gradually let down their guard and started talking about this medicine.

One of them gritted his teeth and said, "If the princess really wants it, I still have some at home and can sell some to you."

Lu Yanluo's face was filled with joy, and she seemed to be unable to wait, so she pulled the person over and started giving him the silver.

Seeing that Lu Yanluo was anxious, the woman quickly asked people to go to the front yard to find her master. Although she knew that her family was selling a very valuable medicine, she only knew that everything needed the man's consent.

Lu Yanluo noticed that the servant left for a while, and soon came back quickly with a man. It was the Chief Justice of Dali Temple, Yan Shaobai.

Yan Shaobai stared at Lu Yanluo meaningfully, and walked away after a while. Yan Shaobai's wife hurriedly urged Lu Yanluo: "Princess, go quickly. Our master is here to look for you."

Search? Lu Yanluo understood. This thing was a banned drug. How could Yan Shaobai dare to trade it in broad daylight? Naturally, he had to find a secret place.

Following Yan Shaobai all the way to an inconspicuous room, Lu Yanluo pushed the door open and walked in. Yan Shaobai looked at Lu Yanluo with a gloomy face.

"I heard from my servants that Princess Ye wants to look for me?"

Lu Yanluo didn't hesitate and said straight to the point: "I want to buy a medicine from you called Mu Si. Your wife said she can sell it to me."

Yan Shaoqing was immediately furious, secretly hating the ignorant woman in his heart! He did not forget to make amends, "Princess, are you mistaken? I have never heard of this thing. The woman in my family is ignorant. I think she said it casually to please the princess. It can't be taken seriously."

Yan Shaobai was obviously going to refuse.

Lu Yanluo's smile disappeared, and she said sternly, "Sir Yan, I won't beat around the bush with you. The housekeeper of the Ye Palace was threatened with this medicine a few days ago. I sent people to investigate the matter thoroughly. Otherwise, how could I have found you? You and several other officials secretly bought Mu Si from Beiliang through the wealthy businessman Jia Jing, and sold it in Beijing at a high price. Yan Shaobai, do you admit your crime?"
