The elders of the Feng family didn't seem to be reconciled, and continued to let Duan Yun refine many other pills with different effects, but they came to the same conclusion, that is, the pills refined by the wraith soul were similar to the pills refined by the human soul, and there was nothing outstanding about them.

However, in further experiments, it was also found that there was a difference in the spirit alchemy, that is, the poison pill refined with the spirit spirit was much more toxic than the poison pill refined by other souls, which was the only thing that comforted the elders.

From the afternoon until late at night, the elders went from being happy to let Duan Yun try to refine various pills, to when their enthusiasm grew cold, few people let Duan Yun refine the pills again.

"Okay guys, I'll stop here for today. ”

Seeing that the enthusiasm of the Feng family elders had almost faded, Feng Wuji finally opened his mouth and concluded: "What can be basically determined now is that the tonic and auxiliary drugs refined by the wraith soul are similar to the elixirs refined by the human soul, while the poison pills refined with the wraith soul have significant effects, and the specific and other special effects of the elixir refined by the wraith soul still need to be studied further." ”

Although Feng Wuji's words were said more tactfully, in fact, every elder present understood in their hearts that the wraith soul did not have much significance for alchemy, because the main function of the elixir was still used to refine tonic and auxiliary medicines, even if the wraith soul was of some help in refining the poison pill, but if it was not helpful for refining the tonic and auxiliary pills, then the effect of the wraith alchemy could not surpass the heavenly soul, that is to say, Duan Yun's wraith soul was not of substantial help to the alchemy level of the Feng family.

Soon, a room of people dispersed, and no one cared about the pills refined by Duan Yun anymore, so no one noticed that at this time, the surface of these pills was shining with an undetectable light. Finally, Duan Yun looked at the tray full of pills and distressed them all into the storage space.

When he got home late at night, he didn't go to sleep immediately, but took out a thick blue book from the storage space.

"Feng's Pharmacopoeia". ”

Duan Yun muttered the name on the bark of the tree, lit the fire and began to read it carefully page by page. Now he has been able to know a lot of words because of the study of the Great Immortal Treasure Record some time ago, and now he can understand nine times out of ten in ordinary books, even if he encounters words he doesn't know, Yuan Bo will teach him, so now words are no longer a problem for him.

This book was given to Duan Yun after the meeting, when Feng Melodious was blowing, and Feng Melodious told Duan Yun that this book is the basic book of the Feng family for internal disciples to practice alchemy, which not only records in detail the common sense of alchemy and many exquisite alchemy methods, but also adds the alchemy experience summarized by the Feng family over the ages.

However, the focus of this book is to teach the method of alchemy, but there are very few records of the prescription, from here Duan Yun can see that although Feng Melodious is not taboo about the method of alchemy, he still has reservations about the prescription, but he can also understand, after all, he is still a person with a foreign surname, and the ancestral prescription of the Feng family naturally cannot be easily handed over to himself, and he doesn't care, the purpose of his learning alchemy is just for his own cultivation and Xiaoxue's growth, and the prescription he knows from Yuan Bo is enough.

By reading the "Feng's Pharmacopoeia", Duan Yuncai has a more comprehensive understanding of alchemy, the classification of pills and alchemists that people often say in the world is just a general classification, in fact, the grade of pills and the level of alchemists can be carefully divided into ten levels, the level of pills can be divided into one to ten grades, and the level of alchemists is one to ten, these levels are one-to-one correspondence.

People are accustomed to call the first to third grade pills as the lower grade pills, the fourth to sixth grade pills as the middle grade pills, the seven to ninth grade pills as the upper grade pills, and the ten grades of the pills are called the best pills.

The level of alchemists is the same, except for the highest level of ten, each level from low to high is classified into three general levels: low, medium, and high, and the highest level ten is also named as special level separately.

The reason why only a person with a heavenly soul can become a high-level and super-level alchemist is mainly because the vast majority of high-grade and above pills need the nourishment of heaven and earth elements, so the alchemist must inject the heaven and earth elements into it in the alchemy, and this can only be done by the heavenly soul alchemist who has the ability to manipulate the heaven and earth elements, and the alchemist of the earth soul and the human soul, even if the refining technique is exquisite, it is impossible to do this.

And even if it is a heavenly soul alchemist, it may not be able to refine all the pills, many pills only need the nourishment of the corresponding attributes, while some pills need the nourishment of a variety of elements, but the average heavenly soul person only has the ability to control one or two elements of heaven and earth, so they can only refine the pills that are suitable for the elements they control.

According to this book, in addition to the classification of pills according to their grades, they can also be divided into four qualities: excellent, high-quality, ordinary, and inferior according to the quality of the pills. Only when the quality of inferior quality is reached can it be called an elixir.

The two pills that I refined indiscriminately according to the methods taught by Yuan Bo are not called pills at all, and according to the name of this book, they are "waste pills". The waste pill is just the appearance of the pill, and even one percent of the medicinal properties of the pill cannot be brought into play.

"Hah-"

Duan Yun yawned loudly, and he realized that it was already late at night. But now that he was looking at it, he didn't want to fall asleep, so he stretched his body, got up and moved a little slightly, and then took out a Qingling Pill from the storage space that he had refined himself at the Feng Family Meeting. The effect of the Qingling Pill is to make people feel refreshed, and he is ready to use the medicinal effect of the Qingling Pill to refresh his mind, so that he can continue to read books with full energy.

But at the moment when he was about to put the Qingling Pill in his mouth, his spirit was suddenly stunned, and his whole body immediately stopped, and then, as if he was enchanted, he quickly took out a large number of pills from the storage space of the space stone, sometimes picked up one and examined it carefully, sometimes stacked the pills into several piles, and then quietly observed. Even Yuan Bo, who was in consciousness, repeatedly asked him what happened, but he didn't answer, he kept fiddling with the pill without saying a word.

An hour later, Duan Yun suddenly burst out laughing, and after laughing, he exclaimed excitedly: "So that's the case!"

It turned out that after Duan Yun took out the Qingling Pill, he was surprised to find that the pill seemed to be different from when it was first refined, according to the identification method of the quality of the pill in the "Feng's Pharmacopoeia", this Qingling Pill should have been an ordinary quality pill when it was just refined, and when he took out the Qingling Pill again, he found that the quality of this pill had actually improved by one level and reached a high-quality quality.

Just now he also read from the book that once the pill is refined, its quality has been finalized, and it is impossible to improve the quality of the pill through acquired methods. But this scene, which is diametrically opposed to the record in the book, is vividly laid out in front of me.

Puzzled, he took out all the pills he had refined earlier from the storage space, and after some careful observation, he was surprised to find that among these pills, there were also individual pills that had improved their quality like the Qingling Pill, but what surprised him even more was that he also found that the quality of some pills was much worse than when they were first refined, and even more so that their quality dropped by one level or directly became a waste pill.

After careful analysis, he had a bold conjecture, that is, those pills that improved their quality should have absorbed energy from those pills that had reduced their quality, so their quality was improved, and the quality of the absorbed pills was reduced, and the initiator of the pills that gave the pills the ability to absorb the energy of other pills was likely to be his ghost.
