Gu Ziyao also frowned in confusion.

"Yes, Xu Shanglv, what's going on?"

Most of the medicinal materials they mainly collect are the more common types such as Ganoderma lucidum and ginseng.

It can be used in a variety of prescriptions, so the demand is also large.

But in summer, people are prone to heat stroke and cold, which rarely happens.

There are so many herbs for treating wind and cold, even if they are bought and sold, they will not be able to return to their original value until at least winter.

Faced with the doubts of the prince and princess, the businessman seemed particularly calm.

He smiled, his eyes full of mysterious confidence.

Xu Shanglu lowered his voice: "Your Highness Princess, Third Highness, you don't know anything about this."

"As the saying goes, 'Know the place to win, choose the place to make money', these herbs for treating wind and cold will soon be available."

"When we go south and north to do business, in addition to relying on some eloquence, but there is one more important thing, what does the third highness know?"

Gu Ziyao leaned against the back of the chair and took a deep breath: "Don't betray me."

Xu Shanglv smiled: "Naturally, it is based on well-informed contacts. As far as I know, Third Highness, someone near the capital contracted a cold-like disease."

"If you come into contact with a patient, you may contract the same disease, so the price of the herbs I sent to His Royal Highness will soon be doubled!"

Gu Nuo'er was stunned, and looked at Gu Ziyao.

The girl frowned and asked, "Are you sure it's the wind chill?"

"The villain has investigated in private and is not sure if it is due to wind-cold, but after observing a few people who got sick, they all recovered after taking the medicine for treating wind-cold."

"The current illness is only spreading around the capital, and has not come to the city yet. As long as His Royal Highness has received the medicinal materials and wait, within half a month, someone will definitely ask for a lot of money for the medicine!"

"These medicinal materials, I'm afraid that the supply will be in short supply! And the third highness spends a small amount of money to make a lot of money, which is an excellent transaction!"

Gu Ziyao was silent for a moment.

After that, he bought this batch of medicinal materials from drug dealers.

And ordered them not to drive up the price of medicinal materials in the capital when there are too many patients.

Because Gu Ziyao knew these merchants, they would keep a small part of the medicinal materials they sold in their own hands.

In order to observe the market at that time, sell it at the highest price, and make another profit.

After listening to Gu Ziyao's words, several businessmen agreed again and again and left with generous rewards.

After they left, Gu Ziyao saw Gu Nuoer frowning, as if in deep thought.

Then he smiled and comforted: "You can rest assured, sister, the three of them, led by Xu Shanglu, are the most powerful drug dealers in the capital."

"As long as they don't let go, the price of medicine in the capital will not rise, and even if someone gets sick, they can be cured."

Gu Nuo'er came back to her senses, and her white porcelain-like face was bright and bright.

"Brother, I'm not worried about the price of medicine. This disease can be cured. I'm just wondering why some people get cold in the hot summer."

Moreover, the symptoms are like wind-cold, but it is not wind-cold, what kind of disease is that?

The third prince said with relief: "I am familiar with medical books, and I also understand a truth. Some diseases may seem strange, but they are actually the origin."

"Presumably this disease is a type of cold, but the symptoms are occasionally different, which makes people a little confused."

He reached out and patted Gu Nuo'er on the shoulder: "Don't worry, the third brother will keep an eye on the drug market at any time, and I'll let you know if I find anything."

"Okay, don't think about it anymore. The food in this inn is good. I'll order some signs and give you a taste."

In this way, Gu Nuoer temporarily took this matter to the bottom of his heart.
