Thank you book friends ~ a good piece of oolong ~ big prize, thank you for your support!

Nie Fei was taken aback, he never thought that this double-edged grass actually had this effect, but it had no effect. He originally thought that the effect of this double-edged grass was to solve the poison of other attributes, but he didn't know that it had no effect. So what is the purpose of adding double-edged grass to this detoxification powder? Is it just a casual addition?

Nie Fei felt that his IQ had been teased by this Dan Fang, and he was slightly angry in his heart, rubbing his hands and throwing the unilateral one to the ground.

But after only a while, Nie Fei stood up, picked up the Dan Fang again, walked to the table, and smoothed the crumpled Dan Fang again. He secretly warned himself that he must be calm in doing things, and he only judged based on one experience, and he thought that the Danfang was unreasonable, which was obviously not objective, and in any case, he had to wait for careful study before making a conclusion.

Nie Fei studied the Dan Fang again. Obviously, the most suspicious herb in the Danfang is the double-edged grass. It is written on the Dan prescription that there is no efficacy. But this double-edged grass always has some characteristics, right?

At this time, Nie Fei remembered that he had a jade plate called "Baicao Illustrated Book", maybe there was an explanation of this double-edged grass in the "Baicao Illustrated Book". Nie Fei immediately opened the storage bag, turned out the jade plate of the "Hundred Herbs Illustrated Book" from it, and the aura probed in, and when he landed, the entire "Hundred Herbs Illustrated Book" was displayed in front of his eyes.

Not to mention, Nie Fei's idea was also correct, he searched for a moment in the illustrated book, and then found the double-edged grass. According to the illustrated book, the double-edged grass grows in a place where fire poison is strong, and it contains a large amount of fire poison, but if you use this grass to practice fire poison exercises, it has little effect, and only a little antidote to fire poison can be dissolved.

Nie Fei was puzzled, what is this, inconsistent. The first said that it contained a large amount of fire poison, and the latter said that these fire poisons had no effect and could be dissolved lightly. Nie Fei couldn't help sighing, this hundred grass illustrated books were also written by people. No matter how high that person's status and knowledge are, it is inevitable that he will make mistakes, otherwise how can there be such inconsistencies. However, is it really the author who wrote this illustrated book that made a mistake? Or I can't understand it, so I put the blame on the author's mistake, which in fact shows that I am incompetent.

Nie Fei stabilized his feelings, and then thought about going deeper. The other three herbs in the pill of detoxification were all used to detoxify fire poison. There are all kinds of poisons in the world of cultivating immortals, and there are poisons of all attributes, why do those three kinds of herbs have to detoxify fire poison? And why does the fourth herb, the double-edged grass, contain fire poison. Isn't it abnormal that an elixir used for detoxification can add poison to it instead?

Suddenly, Nie Fei was shocked, stood up from his seat suddenly, and said to himself, "Could it be ...... Could it be that the fire poison that those three herbs solve is the fire poison in this double-edged grass?" This idea is simply incredible, how can Nie Fei not be shocked in his heart. His idea is not unreasonable. If you don't explain it this way, it's hard to explain why those three herbs can only solve a single fire poison. It is also difficult to explain why toxic ingredients should be added to the detoxification pill.

Nie Fei felt that he had faintly grasped the key to the problem. Those three herbs are used to solve the fire poison in the double-edged grass.

Following this line of thought, Nie Fei continued to think. There is no doubt that the two herbs contain fire poison, and there is no doubt that no one can say anything about using those three herbs to detoxify fire poison. But the question is, why bother, after adding poison, and then using other herbs to solve it, isn't that playing with yourself?

Of course, Nie Fei didn't believe that someone would be so mentally retarded and make such a bullshit Danfang, there must be a reason.

Now, the conclusion is on the horizon. This double-edged grass must be the most critical ingredient in the detoxification powder, and after its fire poison is removed, the rest is the detoxification ingredient.

Nie Fei thought carefully for a while, and felt that the conclusion he had introduced could withstand scrutiny, and there were no loopholes. At this moment, Nie Fei had already understood the detoxification dispersion, and sneered in his heart: "What kind of alchemy, in fact, it is not a chemical reaction? It looks very mysterious, it is a big fire and a small fire, and it is a wood spirit qi and a fire aura, if you look at it in the eyes of experts, it is nothing." ”

......

Originally, Nie Fei had never cultivated the Wood Spiritual Qi, so he had lost confidence in alchemy. However, as soon as he understood the truth of the poison dispersion, he thought that he could also refine the detoxification dispersion, and maybe his own method could not use the wood aura.

"Look at me without wood aura, I can become an alchemist. Nie Fei thought to himself.

Nie Fei thought about it carefully, the most critical issue in the preparation of detoxification powder was how to remove the fire poison in the double-edged grass.

There are two ways to do this. The first method is to use various herbs that can solve the fire poison to remove the fire poison like the one in the Dan Fang. This method, strictly speaking, is a chemical reaction, an organic chemical reaction to be exact. Organic chemical reactions are generally more troublesome and have harsh requirements for various conditions. At this time, Nie Fei thought of Lin Qiao's alchemy again, he was injecting wood spiritual energy into the Dan furnace, and he told himself to fan the wind and increase the fire, in fact, to put it bluntly, he was trying his best to meet the conditions for the reaction.

The infusion of wood aura is to increase the pressure. And to increase the fire, it is to increase the temperature of the reaction.

Nie Fei remembered that Lin Qiao had been tossing for a long time, but in the end he didn't succeed, so he must have not met the reaction conditions. This shows how harsh the conditions of this reaction should be. When Lin Qiao was alchemizing, it was estimated that the conditions of temperature and pressure had not been reached, or the conditions had been reached, but the range of reaction conditions was extremely narrow, and if the pressure was slightly increased or the temperature was raised, the reaction conditions would be missed instantly. In this way, the reaction cannot be carried out, and the pill will naturally not succeed.

As soon as Nie Fei thought that the conditions for this reaction were so harsh, he didn't have much confidence in this method. It's not that he can't do it, but if he wants to succeed, he doesn't have the auxiliary equipment, so he has to keep trying.

This method was too cumbersome, so Nie Fei put it aside for the time being. He tried to think of other ways, and if he couldn't think of any good way, then he had to use the most troublesome and stupid way.

Nie Fei couldn't help but shift his attention to another method, that is, the method he used when extracting the Spiritual Relief Herb. Strictly speaking, it is an extraction method, that is, the immortal nature of the spirit grass is extracted into the water rich in spiritual energy by using the principle of homosexual compatibility, so that the fairy nature of the spirit grass is separated.
