Chapter 4489

Medicine debate is the first step in alchemy... Alchemists must first have a very familiar understanding of the properties of various medicinal materials, and then check the selected medicinal materials one by one before officially starting alchemy. Once substandard medicinal materials are found, they must be replaced resolutely.

Otherwise, if only the quality of the medicinal materials is poor, it will only affect the quality of the final pill, but if the medicinal materials themselves are wrong... For example, two kinds of medicinal materials, both in size and shape, are very similar, but the medicinal properties are different, or even opposite.

If you can't accurately distinguish the differences of medicinal materials when you are refining pills, and mistakenly use medicinal materials B as medicinal materials a for alchemy... In the end, if alchemy fails, it will be better. At most, you will waste a furnace of alchemy materials.

But if you finally refine the pill and let people take it as usual, it is likely to make a big deal... A good pill to replenish qi and gain may become a poison pill that can poison good people!

Therefore, as the first step of alchemy, drug debate is a very important link, and truly qualified alchemists will not ignore this step.

Before becoming a real alchemist, an ordinary alchemist has to be an alchemy apprentice for a long time. As apprentices, they are not qualified for alchemy. Their daily work is to help those formal alchemists deal with a large number of medicinal materials.

This work looks dull and boring, but it is a prerequisite for becoming an alchemist, because only when you are exposed to a large number of different kinds of medicinal materials every day can you have an intuitive and specific impression on the spiritual plants of various medicinal materials. In this way... When he really becomes an alchemist and starts his own alchemy, he won't fall in the link of medicine debate.

Although Lu Shan has never been an apprentice in alchemy, he has a strong spirit and can not look at the knowledge he has browsed.

Moreover, the alchemy knowledge he learned through the jade slips is not just some words or pictures. Many of the contents are recorded by senior alchemists

The so-called shenlu is to directly engrave the things in the memory of one's own soul into the jade slips to form a special brand. When others read these jade slips, they will naturally move all the things in the memory of the spirits to their own minds.

Otherwise, if all the classics of alchemy are converted into words, there may be hundreds of millions of words. Even if the practitioner has a long life, how many people are willing to bother and record them in the jade slips for you word by word!

The method of divine recording is much simpler. Just remember what you need to record in your mind, and then engrave it in the jade slips with a secret method. It is very convenient.

The content of this re engraved spirit is more comprehensive than video images. It includes not only images, words, but even smell and touch.

For example, Lu Shan is identifying a traditional Chinese medicine, chiteng root... When he saw this, all the information about the chiteng root naturally came to his mind.

These materials include the whole process of how the red vine root is dug out from the ground, and then cleaned, processed and dried, as well as the best state when it is finally made into a material that can be used for alchemy. It contains the color, size, cross-sectional texture of the red vine root, as well as the smell and touch of the object, and so on.

So... Although Lu Shan had never really seen the medicinal material of red vine root before today, he was like an alchemist who had dealt with this medicinal material for many years. After simple identification, he had noticed that there was a problem with this medicinal material

Although the color, shape and smell of the red vine root seem to be no different from the real red vine root. However, under the strong divine consciousness, Lu Shan was surprised to find that the color displayed inside and outside of this thing was inconsistent.

Moreover, the texture of the cross section of the red vine root is shallow and slightly messy. In addition... It feels smooth... These are not consistent with the real red vine root.

Although Lu Shan found something wrong, he was not in a hurry to open his mouth. Instead, he patiently checked all the remaining materials. After no other problems were found, he pointed to the dozen red vine roots and said, "please change the red vine roots for me. I need the red vine roots that have grown naturally for ten years, And this... Should be the vine root that has only grown for less than nine years. "

"In the Qingxin pill, although this kind of red vine root is only an insignificant auxiliary medicine, even if it is not added, it is possible to reluctantly refine Qingxin pill. However... If the Ivy root is mistaken for the red vine root in the refining process, it will lead to the reversal of the drug properties of the pill. The Qingxin pill will only become a irritable pill. After taking it, people will not be able to clear their mind and calm their nerves, but will be angry. If they practice in this state, eight to nine out of ten will lead to being possessed by evil! "

"What... Is this Ivy root? It's impossible... "

The elder in charge of getting materials for Lushan just now turned black and said, "it's impossible... It's clearly a red vine root! Ivy roots are not of this color at all. Can I make a mistake? "

Lushan shook his head and said, "this is the green vine root... As far as I know, the red vine root and the green vine root are actually one kind of things, but they were green inside and outside less than ten years ago. It will not turn red from inside to outside until it has grown for ten years, and its leaves will also turn red. "

"Although Ivy root and red vine root are the same plant, their root and leaf properties are not necessarily the opposite before they become red and after they become red. In terms of its value, the red vine root is more than ten times higher than the green vine root, right? I think... After being picked, the Ivy root should be mashed with Wisteria leaves and soaked for a few days to dye it purple. It's just a trick for the drug collector to make more money! "

With that, Lu Shan picked up a piece of chiteng root cut into two inches long and broke it with a gentle force on his hand. The chiteng root was broken into two pieces at once. At the moment, from the broken section... Sure enough, only the layer close to the skin was dyed red, but it was still green in his heart!

Seeing this scene, the elder who just questioned Lushan couldn't help turning black. Without saying more, he grabbed the "red vine roots" and turned around and left.

Their alchemy hall consumes a lot of medicinal materials for alchemy every day. Of course, it is impossible for Liuyun sect to plant so many medicinal materials in the medicinal field! Most of them are purchased from the outside, and the chiteng root was just sent recently and happened to be received by the elder.

At that time, he probably glanced at it and praised this batch of Wisteria roots for their excellent appearance! I didn't expect... I was fooled!

Fortunately, this batch of Wisteria roots has just been put into storage, and this medicinal material is not very useful. It is the first time to use it today, and it has not led to a big mistake. Otherwise... If it is really used in large quantities when refining pills, and other alchemists have not seen through the problems, the consequences are unimaginable!
