Practice overnight.

On the morning of the next day, Qin Xianyu had a long sword on his back, carried the black bee bag beside him, and put important things such as jade pills that could not be lost on his body, brought some small silver taels, put some unimportant things in the room, and left the courtyard.

The search for Yu Jian and the investigation of his parents' illnesses was not easy to start, so he could not find it out and put it aside. As for the engagement, it was not very important, and the girl from the Shangguan family was completely unaware of where she was and had nowhere to go.

After thinking about it carefully, I would go to the prime minister's mansion in the capital and ask about my medicinal herbs.

After leaving the yard and finding out where the Prime Minister's Mansion was located, Qin Xianyu went all the way.

As soon as I walked around a street, I met a man who hurriedly approached the medicine hall.

Isn’t this person the goalkeeper who stopped him last night?

Guo Ping?

Qin Xianyu didn't care much. Just as he was about to leave, he saw Guo Ping in the medicine hall taking out a prescription and reading out many medicinal materials.

After all, he was a doctor, so he couldn't help but be curious, so he stopped and listened for a while before making a guess: "These medicinal materials... seem to be used to treat diseases?"

Qin Xianyu pondered: "From the combination of medicinal materials, this prescription should be used to treat the elderly. Could it be that his parents were infected with cold or what? Judging from the amount of medicinal materials he reported, the disease seems to be not mild."

From a few medicinal materials, you can guess which diseases and the severity of them are. In the past, Qin Xianyu naturally could not do this. However, since he practiced Taoism, he not only had a clear ear and eye, but also had a lot of wisdom in his understanding. He could easily remember the medical skills he had learned in the past, not forget them, and could also integrate them.

Since practicing Taoism, I have never been distracted by external objects. Instead, my medical skills seem to have improved a lot. Many things that were difficult to guess in the past can be easily solved by thinking about them carefully.

Qin Xianyu couldn't help but feel secretly happy when he realized that his medical skills had been in progress.

He patted the hem of the Taoist robe and walked straight forward.

After taking a few steps, a few whispers suddenly came into my ears.

Qin Xianyu's senses are much more sensitive than ordinary people, and he has been even more so since he became the Gangsha. Although the whisper came from the medicine hall, he still listened carefully.

A dull voice said: "The horns of the green fish in this prescription are a little scarce. If you replace this with a dead tree root, the effect is similar."

Another younger voice said, "No, there are many more in our horns."

"What are you talking about? Go and change the medicine quickly." The dull voice snorted a few times, and then said to himself: "The green fish horn is worth more than 20 silver coins, and the dead tree roots are only two silver coins. Anyway, the medicine is similar, so it will be replaced after changing."

Such things like changing expensive medicinal materials to cheap medicinal materials are actually not uncommon among major medicinal schools. As long as people do not die, there will basically be no big problems.

The two medicinal properties of the horns of the bluefish and the dead tree roots are indeed similar, but the medicinal effect of the horns of the bluefish are better. The medicinal effect of the dead tree roots is weaker and easy to septic blood, which is extremely harmful to the body. According to the prescription, the horns of the bluefish are more useful, while the dead tree roots are actually harmful to the body.

Qin Xianyu frowned and stopped for a long time.

In the medicine hall, Guo Ping looked at some medicinal materials that were being wrapped, and suddenly noticed something was wrong. He frowned and said, "Why are the medicinal materials in this last time, but there were some green tree roots, why didn't there be any of them this time?"

The shopkeeper coughed and said, "The horns of the green fish themselves are the roots of the tree. They will change color after being left for a long time. Look at the roots of these trees, they are the same, but the color is not very bright. In other words, the medicinal materials are still aged for a long time, and the medicinal properties are better."

Guo Ping nodded.

At this moment, a voice smiled faintly and said, "Aren't you afraid that the medicine is too good and the treatment will kill people?"

The shopkeeper's face changed slightly.

Guo Ping showed even more anger. When he saw the rude Taoist priest, his face turned gloomy. In his eyes, the Taoist priest clearly took revenge and was rejected outside the city by himself last night, and then he spoke such an annoying words.

Qin Xianyu just smiled and said to himself: "Although the roots of the dead tree are also good, they are ten times less valuable than the horns of the bluefish, and their efficacy is quite different. Moreover, it not only has poor efficacy, but also prone to septic blood and is more harmful to the body."

"It would be fine if it was an ordinary person. Even though the effect of the medicine is slightly worse, it has the effect. If you have the ability to recover, you will be cured soon. But this medicine is clearly for the elderly. Are you not afraid that the medicine is a little less effective, which will lead to the incurable disease and will cause a life of life?"

Qin Xianyu said slowly, saying, "Even if it is really cured for you, the dead tree roots are prone to septic blood. For the elderly, the qi and blood are not as strong as those of young people. If the qi and blood are destroyed by this medicine, it will also be worrying about life."

After he finished speaking, the shopkeeper's face was pale and his eyes were faintly filled with fear.

Guo Ping was even more angry and clenched his fists.

Qin Xianyu said calmly: "General Guo, Qingyu Kejiao is good, but it still costs more than 20 silver coins. I know that a medicinal material only needs two silver coins. With a few herbs, its medicinal effect is not inferior to that of Qingyu Kejiao."

"In addition, this medicinal herb and those herbs add up to only four silver dollars, which saves a lot."

Everyone in the store was quite surprised, and only looked at the young Taoist priest who looked calm and slowly revealed many medicinal herbs.

"He is so familiar with medicinal materials?"

"Who is this Taoist priest?"

"It seems like I'm not old."

Qin Xianyu ignored others' discussions. He reported the medicinal materials and properties one by one. After that, he bowed slightly and turned around and left the medicine hall.

The reason why he pointed out this incident was that Guo Ping changed the medicinal materials. On the one hand, he didn't feel much disgusted with this goalkeeper, and on the other hand, he was really afraid that the dead tree root would weaken the efficacy of the medicine, and he would also septic blood, which would eventually kill people.

This time, Qin Xianyu went to the prime minister's mansion to check how many medicinal herbs he had already asked for. In fact, Qin Xianyu was quite anxious and stopped delaying.

However, shortly after he walked out, he heard the sound of rapid footsteps behind him.

Turning around and looking, Guo Ping had already chased after him.

"Master of Taoism." Guo Ping stood in front of him, bowed his hands and said with politeness: "Last night, Guo Ping was rude, and today Taoist rude repays his grievances with kindness, which makes people very grateful. Guo Ping apologizes here, and I hope the Taoist ruthlessness of my past."

Qin Xianyu shook his head slightly and said, "You are also the responsibility. If I really enter the city so easily, this great master's capital would be too simple. Besides, if I am really a villain and do evil in the capital of the capital, if I find out then, you will inevitably lose your life."

After saying that, Qin Xianyu waved his hand and was about to leave.

Guo Ping wanted to speak but stopped, but in the end he just bowed and bowed.

Just as Qin Xianyu walked out several steps, he suddenly heard a low shout.

"Hao!"

"You Taoist priest, stop me!"
