After being wrongly married, I stabbed my husband to death and became famous throughout the world.

Cheng Mian looked at Li Shu and felt that what she said was dangerous.

“The kind of drug you mentioned can indeed be produced, but it’s harmful to the body. No one with a clear mind would take it casually. Who would do something that is entirely harmful and without any benefit?” Cheng Mian shook his head.

Looking at Doctor Cheng, Li Shu thought to himself, "If only everyone in the world were this easy to fool."

“What if they first deceive people with words, and then let them take it without their knowledge, or use this substance to deceive the ignorant? Doctor Cheng, I heard from those traveling merchants that the Full Moon Sect can make people forget their worries and transcend worldly affairs. This claim is mostly achieved through drugs. Now the price of black feather grass has risen sharply, and a large batch of goods has suddenly arrived. This is really unusual,” Li Shu added.

She could choose not to speak, but she didn't want the dynasty to be too chaotic, as that would increase her risk of dying or suffering inexplicably.

Cheng Mian listened and realized something: "These people are going to sell the Black Feather Grass to the Full Moon Cult?"

“Internal matters are minor. What you should be suspecting now is whether there are spies or infiltrators within this border region, colluding with the Full Moon Cult and the barbarian enemies to increase the circulation of Black Feather Grass in the market.” Li Shu thought for a moment, then asked, “Is this substance addictive?”

Upon hearing this, Cheng Mian suddenly broke out in a cold sweat.

He was stunned for a moment, then said, "The addictive power of this black feather grass isn't very high, but if it's as you say, once someone has experienced that dreamlike feeling, I'm afraid they'll do anything to try it again, which is no different from addiction..."

He understood what Li Shu was saying.

Most of the people who follow the Full Moon Cult are living in dire straits, and these people may not want to wake up, so...

They might take such a thing voluntarily in order to escape worldly troubles.

Although the Great Zhou has black feather grass growing, its growing environment is indeed not as good as that of the barbarian enemies. To collect it in large quantities would require a lot of manpower and resources.

According to Li Shu, this sudden large amount of black feather grass was either specially planted by someone or secretly transported from the barbarian enemy.

If it's the former, then it could be considered a case of treachery within the family, but if it's the latter...

That means the Full Moon Cult and the Barbarian Enemy have reached a consensus...

Thinking of this, Cheng Mian panicked and his face turned pale: "Ali, I need to report this to the general immediately!"

“Before that, I think you should immediately send orders to all city gates to strictly prohibit any traveling merchants from transporting black feather grass. It’s hard to say about other places, but at least this stuff cannot spread from the border.” Li Shu stood there and added seemingly unintentionally.

She believes that now that this product has appeared, and even that itinerant merchants are buying it on a large scale, its momentum is unstoppable.

The Full Moon Cult members will certainly have other ways to obtain this item.

But we cannot tolerate this on the border.

She tends to overthink things.

If she were a suspicious and incompetent emperor, she would surely be angry or suspicious when the Full Moon Cult was rampant, wondering if the border generals were deliberately allowing the circulation of black feather grass.

Loyalty can never withstand questioning.

If doubts arise, discord will ensue between the ruler and his ministers, and a major incident will occur on the border.

So even if she really didn't want to deal with such trivial matters, she still had to give these few words of reminder.

Cheng Mian hurriedly prepared to send a message, but upon hearing that Li Shu wanted to control these itinerant merchants, he felt conflicted: "Some of the medicinal herbs used in the army are prohibited from being bought and sold in large quantities by the general public, such as antidotes for arrow poison and high-quality anesthetics... But this black feather grass is only moderately effective. Although it has some anesthetic properties, its production and other uses are limited, so it has never been prohibited. If the ban is suddenly lifted, it will cause a lot of trouble! Moreover, I... I am just a doctor, and I have no right to strictly prohibit the sale of this item!"

Cheng Mian was also getting anxious.

If what Li Shu said is true, then this herb absolutely cannot leave the border!

"Moreover, our border is different from other places. The natural environment here is harsh, and the official roads are long and difficult to travel. The imperial court has given great benefits to traveling merchants in order to allow them to come here. If the border troops take action to control the freedom of these people to come and go, and if bad words are spread, the preparation of food and supplies for the border will become even more difficult in the future." Cheng Mian suddenly became somewhat dejected.

The journey from the capital to this place is long, so transporting grain and supplies would be extremely troublesome.

To facilitate operations, money was often the primary means of payment, and merchants were encouraged to send goods to the court to reduce its expenditures.

Wasn't the reason he brought so many soldiers out to buy medicinal herbs to intimidate the bandits and prevent the herbal medicine merchants from getting into trouble?

If the government is even more ruthless than bandits, then in the future...

But if we ignore it, there will be consequences!

Cheng Mian couldn't figure out what to do.

Li Shu sat down, feeling less melancholy. After all, she had said what she needed to say, and there was nothing more she could do.

Cheng Mian was like an ant on a hot pan; he immediately wrote a letter and had it sent back to the army.

But this round trip takes time. Now that the medicinal herbs have been purchased, itinerant merchants will be leaving the area at any time. The thought that those black feather grasses will be used on the people of the Great Zhou Dynasty fills Cheng Mian with a sense of guilt.

Seeing Cheng Mian so upset, Li Shu was too embarrassed to admit how much money he had made from this price difference...

In her opinion, the Great Zhou Dynasty was really not up to par.

She had to prepare early, so that even if she couldn't find a secluded paradise to protect herself in the future, she could ensure that she would have enough to eat and drink.

This time she made a fortune from everyone's money, but Li Shu put the extra five hundred taels of silver into her own pocket without any guilt.

Of course, this money doesn't need to be shared with my friends.

Li Shu also took stock of his own assets.

There was still some grain and raw meat in the space, enough for her to eat for more than half a year. There were also some ready-made dishes and dry food, but the remaining quantity was not too much.

After she learned martial arts from Old Yu, she would often offer him some wine as a token of respect, so she consumed it very quickly.

There are still some essential medicinal herbs, and the cotton clothes and quilts I bought last year are still usable.

Now that the weather is warmer and traveling merchants have come, the price of grain has dropped somewhat, but it is still relatively high.

Li Shu took the silver and went to replenish some of his inventory.

A dou of rice cost nearly 120 wen, wheat 100 wen, while millet and beans were relatively cheap, around 30 wen per dou. Li Shu bought 100 shi of each in batches, spending about 300 taels of silver. He also took out more than 100 taels to replenish wine, oil, salt, raw meat, and other necessities.

Including the silver she had saved up before, she still had two hundred taels left in her savings.

Li Shu planned to look for more opportunities to continue trading goods with these itinerant merchants.

It's probably impossible to make a fortune so easily again.

Li Shu didn't bother Cheng Mian, who had not only acquired a large quantity of medicinal herbs but had also just run into the medicinal herbs sent from the capital.

There seemed to be some problems with the batch of medicinal herbs in the capital, and this person was extremely busy dealing with them. Li Shu, on the other hand, was relatively free and continued to practice martial arts to strengthen his body.

However, Cheng Mian's message received a reply very quickly.

Those in charge in the military directly posted notices prohibiting other medicinal herb merchants from purchasing black feather grass. The military is now buying back the goods from itinerant merchants from other places at the original price.

Even knowing that these merchants are driven by profit and disregard the lives of ordinary people, they could only obstruct the entry and exit of the medicinal herbs while ensuring the merchants' interests.

This method is disadvantageous to the army, since such a large quantity of medicinal herbs would cost a lot of money.

Li Shu did not continue to pay attention to this matter.

Because her peaceful days hadn't lasted more than two days, a matchmaker had already come to her door.
