Although Zhang Xuan already knew that Chai Shao was from Wuchuan Prefecture, he gave the Bluestone Sutra to himself and was instructed by Wuchuan Prefecture, which was not his original intention, Zhang Xuan was still very grateful to him.

Knowing Chai Shao will prevent him from taking many detours in the Great Sui Dynasty, especially Li Yuan’s son-in-law, and Zhang Xuan also plans to get to know Li Yuan through him.

Zhang Xuan raised the medicine in his hand and smiled and said, "I went to buy medicine. It took almost a day?"

"Buy medicine?"

Chaisang looked at Zhang Xuan strangely, laughed silently and said, "Didn't anyone tell you?"

"Tell me what?"

"What medicine is there for the Prince of Yan's Mansion? You actually went to the market to buy it. This made other guards know about it and would make you laugh."

Zhang Xuan couldn't speak for a long time, and felt aching in his heart. He spent a hundred guan in vain! That was enough to go to Tiansi Pavilion to drink ten times.

Chai Shao smiled and patted his arm, "Forget it, it doesn't matter, it's a long time to use the medicine anyway! I'll take a small loss as a lesson. I'm looking for you today to ask about the medicine. Have you bought all the medicine?"

"No, I'm not going to have any less. I've gone to several pharmacies and I haven't heard of this medicine."

"This is strange. Let's go to the royal pharmacy to ask."

There are five or six imperial doctors in the Yan Palace, and a pharmacy covering an area of ​​two acres. An old pharmacist is in charge, and there are several medicine children under it.

The old pharmacist's surname is Wang, and everyone calls him Wang Yaoshi. He is nearly 60 years old and is thin and small, but he has a bad temper and always has a cold face.

Pharmacist Wang snatched the prescription from Zhang Xuan's hand. Zhang Xuan was about to point it to him, but he impatiently slapped Zhang Xuan's hand away, "I know, you don't need to talk too much!"

He squinted his eyes and looked at the prescription for a moment, smashed his mouth a few times and said, "You are talking about the purple insect jade pupa!"

"It's this medicine. I went to many pharmacies without it, including Baiweitang. They have never heard of it."

"Baiweitang?"

Pharmacist Wang curled his lips very disdainfully, "There will be good medicines in that kind of chicken feather shop? Let me tell you, they don't even have half of the medicines in your prescription, and then they will use other cheap substitutes to deceive you, and they have been doing this all the time."

"Pharmacist, it won't hurt like this, it's a medicine!" Chai Shao was a little unbelievable.

"Of course, it doesn't matter if the substitutes are common for ordinary people. They also have therapeutic effects, but for you martial artists, the effects are very different. For example, this black silkworm head, they must be sold to you with dried silkworms, right?" Wang Yaoshi opened his red little eyes and stared at Zhang Xuan.

Zhang Xuan nodded, as if the pharmacist in Baiweitang explained to him like this.

"Bad! Which silkworm is not black after drying it? This is the profiteer. The real black silkworm head must be the black silkworm from Luo County, Baling County. It is only available in the Sui Dynasty. It is extremely difficult to raise. You can only go up the mountain to catch it. A pair of black silkworms is worth one or two gold. Your medicine requires at least twenty black silkworms, and the green dragon veins must be the snake galls of the Xiongzhuyeqing, which has not yet been mated, but they use ordinary vegetable green snake galls to pretend. I tell you, after matching your prescription, it will cost at least a hundred taels of gold."

Zhang Xuan and Chai Shao were shocked when they heard this. Good luck, a hundred taels of gold would be one thousand guan.

Yaoshi Wang returned the prescription to Zhang Xuan, "You are new! I will tell you the rules. Just prepare medicines worth less than ten guan. Medicines worth less than ten guan are required to be signed by the Secretary of the Wangfu. For example, the prescription for you must be signed and agreed by King Yan. The amount is too large."

It is not a big problem to get the King of Yan to sign. Yang Qing still owes him five thousand taels of gold. The key is that the medicine that cannot be bought outside. Zhang Xuan asked again: "Is there a purple insect jade pupa here?"

Yaoshi Wang shook his head, "I don't have it here, but I don't know it, unlike those profiteers outside who say the prescription is wrong without hearing it. Perhaps this is a very rare medicine. I have been making it for forty years, but I have never heard of it."

Zhang Xuan suddenly felt cold. Even the old pharmacist who had been in medicine for forty years didn't know what it would be?

Chai Shao whispered: "Prepare other medicines first! Inquire about this medicine slowly."

The two turned around and wanted to leave, and Yaoshi Wang called them again, "I think there may be someone who knows."

Zhang Xuan hurriedly turned around, "Who is it?"

"You go and ask Zhao Wudan, maybe he knows!"

Chai Shao slapped his forehead hard, "I'm so confused! Why did you forget him?"

"Brother Chai, who is this Zhao Wudan?"

"Go to find someone first, I'll tell you as I go!"

The two walked out of the pharmacy, and Pharmacist Wang chased and shouted, "If you ask, tell me, I want to know what it is?"

"Sure! Sure!"

Chai Shao took Zhang Xuan out of the palace and walked into the imperial city.

"The real name of Zhao Wudan is Zhao Dan, a native of Youzhou, and is a deacon of the Imperial Shang Dynasty. Because he is afraid of his wife, everyone calls him Zhao Wudan. He has been traveling around the country for decades and has a wide range of knowledge. There is basically nothing he doesn't know about."

"What is the Imperial Shang?" Zhang Xuan asked in confusion.

Chai Shao smiled and said, "The Imperial Merchants are the caravans of the royal family, half public and half private. They are hung under the Zhike Office of the Honglu Temple, and they are actually private caravans."

Soon, the two of them came to Honglu Temple. Chai Shao had a wide connection and many people knew him. They did not make things difficult for him and asked him to go directly to the government office.

After several turns inside the Honglu Temple, they walked into a small courtyard, but saw a frown middle-aged man using a bamboo broom to clean the yard.

Chai Shao stepped forward and bowed and smiled, "Uncle Zhao, I'm here to disturb you again."

The middle-aged man was Zhao Shan, the manager of the Imperial Shang Dynasty. He seemed to be very familiar with Chai Shao, and he didn't look up and asked, "Is it your father-in-law who has something to come to me again?"

"No! Not today. Today I am here to inquire about something. Pharmacist Wang said you may know."

"That old monkey still owes me the medicine money! What do you want to ask?"

Zhang Xuan stepped forward and bowed and said, "Does Manager Zhao know about the purple insect jade pupa?"

Zhao Dan was shocked all over and quickly looked up at Zhang Xuan. He ignored Zhang Xuan, threw down his broom and entered the room. It took him a long time to hear his voice, "Come in and say!"

Zhang Xuan and Chai Shao walked into the room. The room was clean and tidy, the walls were snow-white, and the ground was spotless. There were only two half-new couches. Zhao Shanyi waved his hand, "Please sit down, you two!"

A glimmer of hope arose in Zhang Xuan's heart. Perhaps Zhao Wudan really knew about the purple insect jade pupa. Zhao Dan poured them a cup of hot tea and sighed: "I am afraid that the only one in Luoyang knows this purple insect jade pupa. I almost died for it ten years ago. Unexpectedly, someone came to me for it ten years later. Could it be God's will?"

"Uncle Zhao, what is the purple insect jade pupa?" Chai Shao interrupted Zhao Shan's feelings in time.

Zhao Dan smiled, "As the name suggests, the purple insect jade pupa is actually a kind of insect pupa. When it is a pupa, it is as crystal clear as jade, and it turns purple after it becomes an adult, so it is called the purple insect jade pupa. The locals call it ice slag."

"Uncle Zhao, where is this kind of purple insect?" Zhang Xuan asked impatiently.

"This kind of purple insect jade pupa does not exist in the Central Plains, but only on the frozen grasslands in the extreme north. For the Turks, this is also a rare medicine. The Turks use it to give birth to children. Women can give birth naturally after taking it when they are difficult to give birth, which is very effective."

"Uncle Zhao means that you can buy it in the Turks?"

"It may not be available in the Turks. This kind of thing is very rare. It is especially afraid of heat and will turn into slurry in summer, so it usually survives in deep frozen soil. And it will only come out of the frozen soil when the ice and snow have just melted. That is the only chance to catch them, so it is very expensive. A purple worm jade pupa can be exchanged for thirty sheep, and some Tiel tribes living in the extreme north will look for it to exchange for sheep with the Turks."

Zhao Shan looked at him and said, "I know what you martial artists want it to do? What you want is actually a purple insect, and the jade pupa is not needed, and the jade pupa cannot be dug at all. It is in the deep frozen soil. Back then I...

Chai Shao interrupted him again, "Uncle Zhao, do you have to go to the grassland?"

"certainly!"

Zhao Dan shook his head again, "But even the Turks may not be able to buy them, let alone the Central Plains."

Zhang Xuan knew very well why Chai Shao interrupted Zhao Shan twice, because the last time he went to the Turkish to buy medicine with Zhao Shan must be Zhang Zhongjian.

At this time, Zhang Xuan had already understood that if he wanted to practice the technique of gathering strength on the bluestone slab, he had to use this purple insect jade pupa. Since Zhang Zhongjian had personally gone to the Turks to buy medicine, it was obviously the most critical medicine.

Thinking of Yuwen Chengdu's peerless martial arts and the unmatched power of the bearded guest Zhang Zhongjian, he knew that this was his only chance to embark on the road of a general, and the martial arts secret given to him by Zhang Zhongjian. If he did not seize this opportunity, he would definitely regret his whole life.

However, Zhang Xuan was as careful as he felt something was wrong. It seemed that Chai Shao had been hinting that Zhao Wudan had gone to the Turks. Is there any other meaning to go to the Turks?

"I heard that Uncle Zhao is going to the Turks soon, right?" Chai Shao said with a smile.

Zhao Dan smiled, "Your information is very well-informed. I really want to go to the Turks in a few days, and I want to do a business, and buy some good furs to come back."

He glanced at Zhang Xuan again, "If Zhang guards want to go with me, they can make friends."

"Did you decide to go to the Turks?" Chai Shao asked in a low voice.
