However, fortunately, the most important point is mentioned in this pharmacology book, that is, when refining poison, you can add some of your own poisonous blood - it is best to be both an antidote and a poison, so that you can refine a unique antidote that only you can solve - of course, this is not absolute, just like his own blood, which can cure all kinds of poisons, maybe the poison he prepares, others may also be able to solve it.

It's just that the probability of this is very low, and it is almost impossible for the cross-meat man and the monkey to meet someone who can help them detoxify.

After thinking about it carefully, Lin Yiran felt that he was still in a hurry, and he planned to take some ordinary poison materials to refine some ordinary poisons first, so as not to waste the poison materials he had spent thousands of acres of space for.

With a stroke of his mind, he took all the poisonous raw materials in the inner world. He looked at these unknown poison herbs and remembered that they had been obtained from Feng Yangcheng, and couldn't help but sigh. Thinking that when he got these medicinal materials, he didn't use them at all, because most of these medicinal materials were poisonous, but unfortunately they were not toxic enough, otherwise he wouldn't need to spend so much space to buy them.

He didn't expect that the first time he used these medicinal herbs was under such circumstances.

The process of refining poison is actually similar to the process of refining elixir, the only difference is that the raw materials used are different.

Because Lin Yiran did not know any recipes for poisons, he could only prepare poisons according to pharmacology. Whether it is a pill or a poison, there are six kinds of medicinal properties: pungent, sweet, bitter, sour, salty and special, in which the medicinal materials with different medicinal properties are mixed together to achieve different effects.

For example, if you want to enhance the effect of a certain medicine, it is not necessarily possible to refine two medicinal materials with the same effect together, and it depends on their medicinal properties. If they have the same medicinal properties, refining them together can enhance the medicinal effect, but if they are two medicinal materials with similar medicinal properties, refining them together will reduce the medicinal effect.

However, if you want to maximize the efficacy of the medicine, it is not simply to put two raw materials with the same medicinal effect together to refine them, and many times you have to add a third or even more kinds of medicinal materials, but if you want to find the best prescription, you need to conduct many experiments, which requires a lot of manpower, material resources and time.

Therefore, this is also the reason why the divine pesticide prescription is so precious. After all, it has accumulated the painstaking efforts of Shennong's life, and it is a prescription that he has researched after countless experiments. The most important thing is that if a person who is well versed in pharmacology gets the Shen Pesticide Formula, he will definitely learn the experience of Shennong's Formula from it, which will be of great help to him on the way to learn the Formula Formula.

Lin Yiran thinks about it now, he gave the god pesticide prescription to Shangguan Siyu at the beginning, and he can be regarded as giving her a very big reward.

The relationship between medicinal properties is far more complex than that of various attributes, among which acid and sweet are two and two are restrained, pungent and salty are two and two are restrained, and bitter and other medicinal properties are not mutually restrictive.

However, these five medicinal properties may be compatible with special medicinal properties, and according to the amount of proportion, it will be directly related to the change of the attribute restraint relationship.

However, this pharmacology book only mentions this, and if you want to understand the specific relationship between various medicinal properties, you need to go deeper into the research.

Fortunately, Lin Yiran just wanted to refine a unique poison for the time being, and he didn't need to study pharmacology too thoroughly.

If you want to understand the medicinal properties of a medicinal herb, you can usually know it by smelling and tasting it. If the medicinal properties of the herbs cannot be determined by smelling, then they can only be distinguished by taste. However, since some unknown herbs are likely to be toxic, it is actually a very dangerous way to distinguish the properties of medicines by tasting them.

It is said that Shennong's tasted a hundred herbs back then and almost lost his life. But because of this, he finally cultivated a body that is invulnerable to all poisons. Thinking about it, Lin Yiran felt that his poisonous body was much easier.

Lin Yiran stretched out his right hand, held a medicinal herb in his hand, and then put it next to his nose, and began to identify the medicinal properties of these medicines by smelling them.

In this way, one by one, he began to identify the medicinal properties of these medicinal materials, and since he was not immune to any poison, when he could not distinguish the medicinal properties of the medicinal materials by smelling, he simply used the method of tasting to distinguish them.

These medicinal materials were not special medicinal materials, so Lin Yiran quickly identified them, and then he classified these medicinal materials according to different medicinal properties, and began to think about how to prepare poisons.

Suddenly, an idea crossed his mind, and he began to mobilize his consciousness to analyze whether these herbs had the same medicinal properties in common. If he could find common ground from these medicinal materials, if he wanted to identify the medicinal properties of other unknown medicinal materials in the future, he would not need to go to such great lengths, he would only need to bring them into the inner space and use his consciousness to distinguish them.

After some analysis, Lin Yiran really found that there was the same substance in the medicinal materials with the same medicinal properties. In other words, except for the special medicinal herbs, the other five medicinal herbs each contain the same substance.

He believes that it is this substance that gives medicinal herbs their properties. Although there are relatively few medicinal materials with special medicinal properties, he can also clearly feel that the medicinal materials with special medicinal properties contain several substances that can determine the medicinal properties at the same time.

As a result of containing these substances at the same time, these medicinal materials do not show ordinary properties, but instead show a special medicinal properties.

For this discovery, Lin Yiran didn't know if he was the first person to know, but he knew that if he didn't have the special sensing ability in the inner world, he wouldn't have been able to discover this secret.

According to pharmacological records, most of the medicinal materials selected for refining poisons are bitter and acidic, so Lin Yiran also selected two medicinal materials with bitter and sour medicinal properties as raw materials according to the records in the books, and began the process of refining poisons for the first time.

Since the selection of some ordinary medicinal materials was used, Lin Yiran easily refined and mixed the two medicinal materials together. When the refining process was over, he found that this was indeed just like what the pharmacology book said, refining a poison that disrupted the operation of the muscles and veins, but because the selection of materials was too ordinary, the toxicity of this poison was not great, and it did not have a big impact on the person who took it, so he simply used it to practice.
