"If I want to take a Shiquan Dabu Pill and know its entire formula, then I must have taken it before, or I must know the smell of all the medicinal ingredients of this Shiquan Dabu Pill so well that I only need to smell the medicine. It’s so easy to tell the difference!”
Xu Yi recalled the prescription of Shiquan Dabu Pill and shook his head slightly in his heart.
"Some of the medicinal materials in this prescription are relatively biased. If I want to reversely derive a complete prescription, I'm afraid I will have to try and understand a large number of medicinal materials before I can do it."
Not to mention the cost of purchasing these medicinal materials, the time required to understand so many medicinal materials is not a small number.
To understand a medicinal plant, you don’t just need to know what it tastes like, but you also need to know its appearance, smell, habits, medicinal properties, year, growth environment, etc.
All in all, even if Xu Yi had a memory palace and a photographic memory, it would probably take several months to fully understand all the medicinal materials.
This obviously does not meet Xu Yi's own needs.
After a slight pause, he thought again.
"But this medicinal material knowledge is still very useful. If I can fill all the medicinal material knowledge into the memory palace, then no matter what tonics or poisons I face in the future, I can easily crack the formula!"
When walking in the world, besides martial arts, there is one thing that makes people most afraid of it, and that is poison!
If used properly, an ordinary person can even kill a first-class warrior with the poison in his hand.
Xu Yi was most worried about this aspect before. If he could understand the formulas of all poisons, as long as he understood certain medical principles, he would no longer be afraid of these poisons.
Decided!
Tomorrow, no, I will buy a batch of medicinal materials to try out later!
Anyway, he will be refining Shiquan Dabu Pills here for the next day and night, and there is a shopkeeper Chen who is familiar with various medicinal materials next to him. Wouldn't it be a waste if he didn't borrow it?
"correct."
Xu Yi seemed to have thought of something and asked Shopkeeper Chen.
"Shopkeeper Chen, do you have ginseng from other years here? I want to change the age of this batch of ginseng, from fifteen to twenty-four years old, which corresponds to one batch each year."
"Well, ginseng does exist. But if you change it like this, it will have a great impact on the refining of Shiquan Dabu Pills. If the difference is about one year, it will be okay, but if the difference is two to three years, or even four to five years, then The difference is huge!”
"What does it matter? According to the difference in potency, wouldn't it be enough to reduce the other medicinal materials accordingly?"
Xu Yi said casually.
Shopkeeper Chen smiled bitterly upon hearing this.
"Master Xu, this refining does not mean that the main ingredient is old and then the potency of the compound is reduced. It involves a very complicated fusion process of medicinal potency. Every time you make an elixir, you must strictly follow the corresponding measurement. , if there is a little less, this batch of elixir may be useless!"
He earnestly tried to persuade Xu Yi not to make those unnecessary attempts.
Of course he saw what Xu Yi was thinking, and he just wanted to try out whether it was possible to improve the Shiquan Dabu Pill.
But this prescription was worked out by his ancestors after countless years of painstaking research. How can you improve it by just tinkering with it?
All I can say is that young people are so ambitious!
Shopkeeper Chen didn't care how much Xu Yi lost in the end, but he was worried that Xu Yi would blame these losses on him in the end!
In order to prevent himself from being affected by the Xu family's anger in the future, he could only do his best to persuade him.
Xu Yi was noncommittal upon hearing this and just asked a seemingly unrelated question.
"Shopkeeper Chen, if you make a furnace of elixirs, how many elixirs do you usually get?"
"Huh? The number of pills is not necessarily certain. Sometimes if you are lucky, you can get nine pills. Sometimes if you are not lucky, you may get six or even five pills. Generally speaking, seven pills are more normal. "
"Seven Chengdan? This is six hundred taels of silver."
"······"
Shopkeeper Chen looked at the six hundred taels of silver notes in his hand and became a little silent for a moment.
There are seven pills in one furnace, and seventy pills in ten furnaces. According to the price of eight taels of silver each, that is five hundred and sixty taels.
They just threw six hundred taels of silver into his hands, what else could he say?
"I'll prepare the corresponding medicinal materials right away!"
Shopkeeper Chen turned around and went to prepare new prescriptions.
Anyway, he has done his part and told all the disadvantages of doing so. Even if Xu Yi loses a lot of money in the future, it will not be his fault.
As the shopkeeper of Biankang Pharmacy, although he is not a professional doctor, shopkeeper Chen still has some abilities. He can mix the new prescriptions according to the corresponding proportions in a short time.
"Master Xu, the medicine is all ready, can we start?"
Shopkeeper Chen looked at Xu Yi and then at the people behind him, as if he was asking the question 'Who will learn'?
Xu Yi did not reply to Shopkeeper Chen's question, but just said lightly.
"let's start."
Shopkeeper Chen had doubts, but since the 'financier' had spoken, he naturally had no choice but to comply.
"Then I'll start... Master Xu, when it comes to refining medicine, there are three main things to pay attention to. One is the weight and combination of the medicinal materials, the second is the control of the heat, and the third is the timing..." ····”
Maybe it was because he was trying to show his kindness, or maybe it was because the money given by Xu Yi was very appropriate. In short, shopkeeper Chen was very serious in his explanation.
Xu Yi listened very carefully and asked a lot of questions from time to time. Basically, they were all embarrassing questions.
Shopkeeper Chen was secretly shocked when he heard this. If it weren't for the fact that some of the questions were very basic, as anyone who has been exposed to medical skills would understand, he would have almost thought that Xu Yi had studied medicine, and his level was not low.
Really, even apprentices who have studied with him for several years may not be able to ask some of these questions - they are too targeted!
'Maybe this is a gift! '
Shopkeeper Chen thought to himself, while teaching more seriously.
You can’t be serious!
As for some of the questions Xu Yi raised, especially the latter ones, if he didn't deal with them seriously, he might not be able to answer them.
wrong!
I can’t answer it anymore!
"This this······"
Shopkeeper Chen listened to Xu Yi's last question, and the only medical knowledge in his mind was spinning wildly, but he couldn't think of how to answer it, so he could only say helplessly.
"I'm sorry, Master Xu, your question is beyond my ability. I really can't answer it."
He looked ashamed. As a medical student, in less than half an hour, he was asked by a person who had never been exposed to medical skills and had no way to answer. How could he accept this?
Xu Yi shook his head slightly.
"Then forget it."
"Thank you, Master Xu, for your understanding!"
Shopkeeper Chen breathed a sigh of relief.
But at this moment, Xu Yi took out a medicinal plant.
"Shopkeeper Chen, can you tell me about these medicinal materials? I'm very interested."
Shopkeeper Chen:? ? ?
This is another price! !
