Ye Qingyang saw Wang Baishi's deviant assumption, which reminded him of the great change in the history of the development of pharmaceutical medicine in the middle of the Middle Ages of the Saints.

The very beginning of that revolution was also caused by such a deviant conjecture that even the person who proposed that conjecture might not have imagined that his own conjecture would completely overturn the empirical method of concoction, which has been passed down for more than 2,000 years.

You must know that the empirical medicine concoction technique has become a system of its own at that time, which can be regarded as extremely perfect.

Although there are very few introductory books on cultivation in the Star Library, there is no shortage of introductory books for various histories, as far as the history of the development of medicine is concerned, the Star Library contains a large number of related biographies and chronicle history books, as well as a lot of poems and novels, most of which are stored on the fourth and fifth floors of the Star Library.

Ye Qingyang, who went up to the top two floors, on the basis of knowing a lot about that period of history, after reading a round of descriptions in those books, already had a very clear concept of the evolution of medicine in the human race of Jiuyao Xingzhou in his mind, although he could not count the treasures, but the overall context was still very clear.

As a person who wants to study pharmacy in the future, if he can understand the development of pharmacy, it will be of great benefit to him to understand the current drug conditioning system.

Pharmacy is a discipline that studies how to mix various star medicine plants to make a better effect and easier to absorb soul medicine.

In the ancient to early Middle Ages, to blend several star medicine plants into a soul medicine, all the tool needed was a good medicine pod.

At that time, the writing of prescriptions was composed of the required star medicine plants and the related quantity and quality, and this ancient prescription can be said to be quite rudimentary, and compared with the current new prescriptions, the information carried is too little.

At that time, after any pharmacist got the prescription, if there was no original pharmacist who researched the prescription to guide him, the first step to be carried out was to spend a large amount of star medicine plants to find out the concoction technique by himself, which also led to the fact that the soul medicine that the pharmacist at that time generally mastered was very simple.

If a Martian soul hunter wants to become a pharmacist, he must have a master to get started, and at that time, there were many factions of soul medicine in the circle of pharmacists, and generally there was only one faction of people who mastered the concoction techniques of a soul medicine, and most of the soul medicines mastered were inherited from the masters, and there were very few pharmacists who could create new soul medicine prescriptions by themselves.

It's not that there was a shortage of people with a talent for concocilation, but that it was prohibitively expensive to create a new prescription.

In order to create new prescriptions and concoction techniques, many pharmacists have scattered their wealth and have to rely on major forces, and some people have only researched one kind of soul medicine in their lives, which is a good situation.

Therefore, how can such a concoction develop and flourish, and how can such a precious concoction technique be willing to be taught lightly.

The so-called empirical method of medicine preparation is to accurately put the star medicine plants required for the preparation of soul medicine into the medicine tripod one by one according to the number and quantity described in the prescription, and then the medicine master will induce and condense the fire of the medicine mixture, and put it into the bottom of the ding for smelting, and the star medicine plants will be blended.

First of all, it is necessary to use high temperature to refine and refine the sap of the plant soul power contained in the star medicine plant, and gradually remove unnecessary impurities.

Then, according to the slight changes in the juice, at different time nodes, by injecting various complicated fire control seals into the fire of the medicine, the fire of the medicine is sent out of the fire of fire at an appropriate speed, so that the juice is blended and refined, and finally condensed into a ball, and when the phenomenon of medicine appears, the soul medicine can be produced.

Perhaps the pharmacist's grasp of the time node can still be solved by listing the schedule and marking the node, as long as the time of each step of the pharmacist is accurate to the slightest.

However, the mastery of the fire control seal can only be judged by experience, and only by constantly trying to blend and repeatedly perceiving the changes in the juice can we know whether we have mastered a certain fire control seal.

In order to make a correct fire control seal, the most important thing is a sense of mystery and mystery, and the role of the master is reflected at this time.

The master can watch the apprentice control the fire from the sidelines, constantly correct the apprentice's feelings in the failure after failure, grasp the changes in the fire of the medicine, and then smoothly make the correct fire control seal, so that he can have the opportunity to successfully blend a soul medicine.

Each kind of soul medicine has a set of corresponding fire control seals, which cannot be described in words, all rely on experienced masters, a set of demonstrations to teach apprentices, everything depends on experience, so it is very difficult to learn medicine to become a medicine master.

At that time, the soul medicine was a rare item, and some simple low-level soul medicine was even regarded as a heritage treasure or heirloom, which was rarely circulated in the market, and was only mastered by the big forces, and the function was relatively simple, mostly based on the most practical healing class and impact star soul power realm.

The determination of the level of a pharmacist is not determined by whether the concoction technique can reach the desired level, but by the concoction of a soul medicine of the corresponding level.

Even if the medicine dispensing technique is not up to par, as long as you are lucky enough to mix the soul medicine in the assessment of the Drug Dispensing Guild, you can be regarded as a pharmacist of that level.

Or in public, if the soul medicine is successfully concocted, and many people testify, the medicine mixing guild will also collect this kind of information and issue a certificate of the level of the medicine concoctor, even if he has only succeeded once in his life, no one will question that level.

Because of this, the status of ordinary pharmacists at that time was generally not high, and the resources used by the big forces to cultivate or support a pharmacist were relatively light in value compared to the few soul medicines that the pharmacist had concocted, and the former was often greater.

The probability of blending star medicine is too low, and the empirical medicine preparation technique is too difficult to master, resulting in the drug preparation major becoming a thankless major.

Therefore, the high-achievers of this profession have always been gray-haired old men, and they have been able to climb to the top of this profession with many years of deep experience in drug mixing.

Only the old-timers of this kind of medicine concoction profession are the guests of the major forces, if it is not for the big forces or a big man who urgently needs some kind of soul medicine, few people are willing to spend a lot of money to ask the pharmacist to mix.

Sometimes the value of soul medicine is higher than that of the pharmacist himself, if the powerless pharmacist travels, if he does not know the concealment of his identity and is known by a vicious person, the risk is much higher than that of the ordinary soul hunter, and these factors add up to make the pharmacist a profession that can only appear openly in a big power or a big family.

The development of empirical methods reached its peak in the early Middle Ages, among which Qin Hanzhi, a master of medicine concoction at that time, wrote a book "Nine Chapters of Dan Notes", which collected the empirical methods of ancient pharmaceutical concoction.

In the nine chapters of the Dan Note, the first three chapters of the Dan Note respectively elaborate on the three major methods of identification, such as looking, smelling, and asking, which laid an important foundation for the summary of the "four distinctions" in later generations.

The three chapters are named as Yaoding, Removing Impurities, and Turning Fire, respectively, and the Yaoding chapter expounds the various structures and types of Yaoding, and analyzes the impact of each component on the blending process.

The Miscellaneous Chapter analyzes what impurities are, how to remove them and the impact of impurities on Cheng Dan, etc., while the Fire Condensation Chapter analyzes and introduces the fire of medicine concoction transformed by the soul hunter.

The last three chapters are the last three steps of fire control, condensation, and Cheng Dan, which are the last three steps of concocting soul medicine, and Qin Hanzhi analyzed and summarized these three steps, integrated them into his own understanding, and made them simple and easy to understand.
