Long Fei repeated the voice of the woman in the light curtain just now: "So this time, I have to pick out the parts that can be used medicinally among these medicinal materials, and judge when they can be used, and in addition, I have to change the prescription ......."

Long Fei glanced at the row of bookshelves indicated by Jin Guang, thought about it, walked to the bookshelf and started, just like when he was on the first floor, but this time it was more difficult than just now, because these medicinal materials are not just the same medicinal properties, but fortunately, most of the treatment of these medicinal materials is still on the same disease, and this time Long Fei is lucky, among these medicinal materials, most of Long Fei is known.

Long Fei muttered to himself: "This time, not only do you have to memorize these medicines, but you also have to understand them......

Probably because this time not only to identify the medicinal materials, but also to improve the prescription, the time to read the book was extended from half an hour to an hour, and after an hour, Long Fei found that the book in front of him could not be opened, he was stunned and reacted, the time for his reading had come, and he glanced at the book in front of him with some pity.

This time Long Fei still finished looking for all the materials he was looking for, and after Long Fei finished looking for it, he just happened to have half a book left in his hand, so he flipped through it casually, but this time, Long Fei found that these seemingly randomly placed books had a great background.

Long Fei was once in a big world with a ghost doctor, and by chance, he saw a medicinal herb from the Demon Realm.

There is indeed a demon race in this world, and according to legend, in ancient times, when the continent was not divided, the human gods and demons originally coexisted in the same continent.

At that time, because of its strong strength, the Protoss occupied the place with the most abundant aura, and the demons needed to use demonic qi because of cultivation, and the demonic energy was transformed from aura, so the Protoss and the demons often went to war, and the human race was under the pressure of the two, and few of them were able to cultivate with the help of aura, so the strong people of the human race began to seek other ways at that time.

It is also because of the efforts of generation after generation that the Terran warriors began to use their vitality to strengthen their bodies, and gradually formed a complete set of cultivation processes.

Later, the continent was divided, and some people even wondered if there really were gods and demons, but it is undeniable that in anyone's mind, the gods and demons represent absolute power.

However, the book that Long Fei saw here recorded that there were only medicinal herbs produced in the Demon Realm, and even behind many medicinal herbs, the names of some medicinal herbs that could be used to replace them were also marked, which made Long Fei sigh greatly, how bold and careful the person who wrote this book at that time was and dared to challenge.

Long Fei glanced at the collection of books with some pity, and thought in his heart: "After this time is over, I will go back and rest for a while, and I will continue to come next time to finish this book." ”

But although he thinks so, it is impossible for Long Fei to leave this tower and come in immediately, first, he is not just here alone this time, because he has just finished reading so many medicinal materials and alternative medicinal materials, as well as some prescriptions, Long Fei feels that he needs to digest this knowledge well.

With this in mind, he turned his head and walked towards the barrier.

Long Fei stood next to the golden enchantment, lightly tapped the enchantment with his finger, looked at the four completely different leaves in the middle of the golden frame, and said: " Although these herbs look completely different, they are actually from the same herb, this herb is produced in the weakest place of the demon world's aura, and its function is to transform the heaven and earth aura into demonic energy, so that the demons can cultivate, this is the most important herb for the demons, and it is also the most common herb, therefore, this herb in the demon world, rarely receives attention. ”

Back then, Long Fei and the ghost doctor encountered this herb, this herb is called Demon Heart Grass, it looks very cute, the top leaf is heart-shaped, emitting a faint blue light, and under this heart-shaped leaf, there is a row of light blue leaves like feathers, growing side by side, under these three rows of feather-like leaves, there is a layer of sword-shaped leaves that are wantonly like swords, guns, swords, and halberds, and at the bottom of the herb, there is a layer of blue-green, almost wrapped in thin iron scales like hard grass blades.

Although there are four completely different leaves growing on a single herb, it looks like it has a faint feeling that makes people very excited.

When he saw this herb at that time, Long Fei remembered very clearly that the ghost doctor's mood was vaguely better, and he was even interested in explaining to them carefully the shape and function of this herb.

Long Fei still remembers what the ghost doctor said, this herb is produced in the Demon Realm, and other places besides the Demon Realm cannot allow this herb to multiply, but if this herb is taken to other places to be planted, then this herb will automatically absorb the aura between heaven and earth, and transform it into demonic energy, not only feeding himself, but even making the aura of one side of heaven and earth all converted into demonic energy.

Of course, the place can't be very big, that is, a room is about the same size.

However, this herb was born in the Demon Realm, and it also has the talent of some creatures in the Demon Realm.

The creatures of the demon world, except for a few other races, are extremely beautiful in appearance, and between a smile and a smile, there are thousands of styles, which is very exciting.

And underneath this bewitching exterior, they also have a strange attraction, which can easily make people admire and love them.

To some extent, this herb is extremely similar to the clansmen of these demon races, and it can emit a strange fluctuation that makes people invisibly have a good impression of it.

After saying this, the ghost doctor took out an eight-rank pill that he had refined with his own hands and exchanged this demon heart grass for it.

After changing to the Demon Heart Grass, the ghost doctor and the Demon Heart Grass lived in the same room every day, and even Long Fei sometimes went to the ghost doctor's room to help him with chores, or when he did other things, he would occasionally see the ghost doctor with an extremely affectionate affection, whispering to the pot of Demon Heart Grass.

Long Fei even remembered that once, a big family with a good impression of the ghost doctor, the barbaric eldest lady, because she wanted to attract the attention of the ghost doctor, used her whip to hurt a leaf of this demon heart grass, but she was directly abolished by the ghost doctor, and also used poison to burn the girl's face like a ghost.

Long Fei patted his forehead, patted these memories of his previous life back into his brain, and stopped thinking about them.

He glanced at the enchantment, which already showed that Long Fei's answer to this question was correct.

Long Fei glanced at it, and the Demon Heart Grass in the place that had dimmed thought for a while, and always felt that the ghost doctor looked at the Demon Heart Grass's gaze, which made him vaguely feel a little familiar, but Long Fei lowered his head and thought for a while, and he didn't think that the ghost doctor had expressed such emotions about which herb.

Long Fei thought for a while and couldn't solve it, so he simply stopped caring about it, walked to the screen of the next question, and answered the question of the herb.

As the ghost doctor commented, Long Fei has a very solid grasp of the basic knowledge of medicinal materials, among these medicinal materials, although some of them are not produced in this world, for Long Fei, there is no big problem, he quickly answered all the questions here, not surprisingly, all the answers are correct.

Long Fei guessed that the most difficult thing in the second layer was not these theoretical things, because although these things could be said to be vast, if they were someone with a heart, it should not be too difficult to answer.

However, these people who only know about endorsement do not have much effect except for being able to write some records and books on medicinal materials, and if they only know about medicinal materials, they will not be able to become an excellent alchemist. Therefore, actual combat is essential.

Having said that, Long Fei had never seen any alchemist try to improve the prescription as the first step in actual combat.

The prescription that appeared in front of Long Fei at this moment was obviously not a prescription that most ordinary people could use, because Long Fei had seen a lot of medicinal materials that were only produced in the Demon Realm on top of that prescription, Long Fei thought back to the book he had just read, and sure enough, he found the names, types and medicinal properties of most of these medicinal materials on it.

Immediately afterwards, the voice made Long Fei inexplicably familiar with the female voice appear again: "Next, please ask someone who is destined to improve this prescription, and replace the extremely difficult to find medicinal materials on this prescription with ordinary medicinal materials, or easier to find medicinal materials, during the period, there needs to be a relatively clear control of the changes in the efficacy of this prescription, at least for the medicinal properties of this pill prescription, it will increase or weaken the effect, and whether it will produce side effects harmful to the body, what are these side effects?" ”

Long Fei took a closer look at the prescription, and then thought about it in his mind.

Although most of this prescription was produced by the Demon Realm, to Long Fei's surprise, this prescription turned out to be a prescription for treating people who were unable to cultivate due to their vitality disorders.

But I don't know why, Long Fei always felt that this prescription had a very strange sense of disobedience.

As for why he chose such a piece of medicinal materials from the Demon Realm to treat the vitality of human beings, it was probably because such a prescription was rarely studied, and there would not be the kind of situation where this question was used to assess an alchemist, but the alchemist happened to know the answer to this question because he had seen this prescription before.

After Long Fei was distracted for a moment, he began to think about what kind of medicinal materials could be used to replace a certain medicinal material in this prescription, and it could also make this prescription not produce any major changes in effectiveness.

Wu Golem looked at the window on the third floor, and seemed to be able to see through the window whether Long Fei was thinking about the answer to the question at the moment, or because he couldn't answer the question, he was about to be cleared out by this tower, she was a little annoyed and said: "What's the matter with Long Fei? Why did it take so long, I would have let you go, really, this store won't do business, why didn't you say it would be discounted earlier, if he said it earlier, you would definitely be more sure than Long Fei to go, at least it should have come out now." ”

These days, in order to make Wu Puppet care more about himself, the ghost doctor is busy changing clothes and hairstyles, so that he finally gets his sister's praise for not touching his feet all day, but it turns out that it is because of this reason, for a while, the ghost doctor doesn't know how to describe his busyness these days.

He glanced at the delicate brocade robe on his body, sighed, and said to his sister: "If you are still not satisfied, or when the dragon flies out, I will go in again, no matter what, I can give you a chance to get a five-percent discount." ”

As for waiting for the ghost doctor to come out, whether Long Fei will be because of it

What kind of psychological frustration does the ghost doctor have, I'm sorry, the ghost doctor has never had this idea, although it needs to be taken seriously, but the sister is the treasure of the ghost doctor, for the sake of the sister, what does the apprentice think, what's the big deal.

The ghost doctor had already casually decided that after Long Fei came out, if he didn't reach the third layer, Long Fei's fate.

However, in his heart, he had indeed begun to calculate, after Long Fei came out, if he really needed to go in again, what should he come up with to make up for Long Fei's lack of knowledge and insights at the moment, in this regard, he felt that he was very reasonable, because Long Fei was his disciple after all, he might just accept such an apprentice, and naturally he would build Long Fei into an excellent alchemist in all aspects.

And as a very good alchemist, how can he lack basic knowledge?

Although the ghost doctor will hit people to the point that he can't do it on the surface, but after the addiction is over, he will indeed make up for the missing part carefully.

If you can find this kind of moisturizing and silent goodness, you will naturally feel that this is the best person in the world for yourself, but if your mind is not sensitive enough to see these subtleties, you may feel that this person may be the worst and worst person in the world.

The puppet gently pulled the clothes on the ghost doctor's body, and said to the ghost doctor: "If Long Fei really doesn't reach the third layer, he won't be there, you still don't want to go, what are you going to do, bullying the weak?"

Although for the ghost doctor, re-entering the tower is not much different from bullying the weak, but for other teachers, the problem of this tower is really tricky and weird.

Whoever said that breaking into this tower was to bully the weak, maybe those alchemists would be angry and blow up their alchemy furnaces.

Even in Long Fei's heart at this moment, it was because of these thoughts.

Long Fei has tried a lot of medicinal materials now, but these medicinal materials are more or less in his calculation process, which will produce some changes in the final effect of this elixir, this kind of change is not the kind of change that is harmless and can only be called a side effect, but will make a great change in the efficacy of the entire medicinal material, and even sometimes, it will directly make this prescription can no longer be used in medicine.

This is not to say that Long Fei's ability is not good, the problem is that the alchemist who created this prescription at that time must have already polished this prescription to a very round degree through various means, how could it be possible to make this prescription look like there is no trace of modification at all?

Besides, this prescription itself is a prescription for the Sanpin Pill, and for most alchemists, it is very good to be able to successfully refine it, let alone replace the medicinal materials of this prescription with a medicinal material that is completely infallible and in the same world.

I'm afraid that the person who came up with this problem at that time may not know all the solutions to this problem.

Long Fei rubbed his head and continued to calculate the prescription, suddenly his eyes lit up, and he muttered to himself: "I was also wrong, why do you have to use a medicinal herb to replace these medicinal herbs from the Demon Realm?"

Long Fei calculated quickly in his brain, and muttered in his mouth: "If I remember correctly, the combination effect of these two medicinal materials is just right, and it is almost ...... like this."
