So, can this extraction method be used on double-edged grass? Nie Fei felt that this method made sense theoretically. It is now almost certain that the double-edged grass is composed of many components, one of which is fire poison, there is no doubt about it. As for the remaining components, although Nie Fei didn't know what they were, the effect was that they could detoxify, and knowing this, it was almost enough.

Of course, Nie Fei never thought of extracting those things that he didn't know what the composition was and had detoxifying effects. I don't even know what they are, and what kind of solvent to choose? So if you follow this line of thinking, you will definitely be at the tip of the horns, and it will not work at all. But he knew the exact ingredient of the other kind, fire poison, so the method was simple. Just extract the ingredients of the fire poison, and the rest, isn't that the detoxification ingredient?

In fact, isn't the so-called alchemy also using those antidote herbs to eliminate the fire poison ingredients? The method that Nie Fei thought of was just a different form.

But there is another key problem, that is, the fire poison and antidote ingredients in the double-edged grass are not connected. In other words, fire poison is a separate molecule and cannot be mixed with the rest of the molecules. Otherwise, this extraction method will not achieve the effect of extraction. For this problem, Nie Fei still has some bottom in his heart, which can be explained by reverse deduction. Assuming that the molecules of fire poison are combined with other molecules, then those several detoxifying herbs, after dissolving the fire poison, are bound to change the molecular structure and become another substance. According to this reasoning, this substance is the detoxification substance. However, the illustrated book clearly says that in the double-edged grass, the toxicity of the fire poison is minimal, which means that there are antidote ingredients in the original double-edged grass, which is neutralized with the fire poison, so that the toxicity is not revealed, and it is not obtained by the guò reaction later.

Obviously, the assumption that these molecules are bound together is not valid, and it can be deduced that their molecules are separate.

......

If it was said that the fire poison in the double-edged grass was extracted, Nie Fei had already had his own ideas. He has a lot of fire feather beast inner pills on his body, and the inner pill is a thing that contains fire poison, and it is completely possible to use the medicinal liquid made from this inner pill as a solvent to extract the fire poison in the double-edged grass.

Nie Fei said that he would do it, and began to prepare.

The compound is very secluded, and almost no one comes. What made Nie Fei feel even more commendable was that since Lin Qiao failed in alchemy, he had locked himself in the room all day long, not taking a single step, and he didn't know what he was doing. Nie Fei didn't have to worry about this, in short, it provided him with convenience.

When it comes to preparation, of course, the first step is to prepare the materials. The Inner Dan of the Fire Feather Beast, Nie Fei has a ready-made one, and now he only needs to find some double-edged grass.

Lin Qiao has a warehouse dedicated to storing all kinds of medicinal herbs, which is usually locked by a large lock. But in order to facilitate Nie Fei to take medicine for him, Lin Qiao specially assigned Nie Fei a key, so Nie Fei entered the warehouse without much effort, and he could enter by opening the lock.

However, after Nie Fei entered the herb room, he searched for a long time, but he did not find a single double-edged grass. This made Nie Fei quite wondering, it stands to reason that Lin Qiao is refining detoxification powder, this kind of conventional double-edged grass should be prepared in sufficient quantities, how can it be used up?

Out of the herb room, Nie Fei is not out of the way to think. In the Hundred Refining Gate, there were many places that specialized in selling all kinds of medicinal herbs, so Nie Fei left the courtyard and rushed to the nearest place that sold medicinal herbs.

Five miles out of Lin Qiao's courtyard, he came to the place where the herbs were sold. Nie Fei came to the door, only to see that the place was just an ordinary house, nothing unusual, on the lintel of the main entrance, a signboard was hung high, on which the words "Baicaotang" were written, quite a bit of the flavor of a trader.

There are a lot of people coming in and out of that place, which shows that business is not bad. In fact, if you think about it, you can figure it out, here and there, there are all alchemists, and medicinal herbs are the necessities of alchemists, and the need is very large, and it is strange that business is not good.

As soon as Nie Fei appeared at the door of Baicao Hall, people who came and went glanced at him. For them, almost everyone around them knew each other, but Nie Fei was a fresh face, so they couldn't help but pay attention to Nie Fei.

It's not a big deal, Nie Fei didn't care, everyone was curious about strangers, it was nature. Nie Fei strode into the Hundred Grass Hall.

In the Baicao Hall, there is a long counter, and there is only one person selling herbs in the back, who is busy checking the herbs for customers. There were more than a dozen other people in the hall, all of whom were customers of Baicaotang.

Nie Fei's awe-inspiring appearance walked into the Baicao Hall, which immediately attracted everyone's attention, and even the disciple who sold the medicine temporarily stopped his movements and looked at Nie Fei in a daze. Nie Fei's expression was indifferent, his eyes slowly scanned around the Baicao Hall, took square steps, and walked towards the counter.

Everyone had never seen Nie Fei before, and seeing that he was a stranger and had such an imposing momentum, they couldn't help but speculate: This kid is so big, I don't know what the origin is?

The disciple who sold the medicine greeted with a smile: "Oh, this senior brother has never seen it, I don't know which elder's disciple?"

Nie Fei said lightly: "My master is Elder Lin Qiaolin. ”

Nie Fei noticed that as soon as his words came out, the expressions of everyone in the Hundred Grass Hall immediately changed. They were stunned for a moment, and then someone chuckled and said, "Hehe, Elder Lin has finally found another disciple." "yes, it's not easy. Someone even arched his hand towards Nie Fei, and said with a grin on his face: "Congratulations, junior brother, it is really gratifying to be able to become a disciple of Elder Lin Qiao, this is really the greatest blessing in your life, haha." ”

How could Nie Fei not be able to see the ridicule of these people? Although he already knew a little about Lin Qiao's affairs and didn't care about it in his heart, these people were still uncomfortable in his heart. But there's nothing to be done about it, you can't tell them that my master Lin Qiao, what a good pen, right? The fact is, Lin Qiao is not a good pen at all, if Nie Fei said that, he would have to laugh off other people's big teeth.

Nie Fei didn't pay attention to it, came to the counter, and said to the guy, "This senior brother, I need two double-edged grasses. "Nie Fei knew that the guy in the Hundred Grass Hall was also a disciple of the Inner Sect of the Hundred Refining Sect, so he called that guy Senior Brother.

A look of disdain flashed in the man's eyes, and he said impatiently, "Don't you see that I'm busy? You go over there and wait in line, and when it's your turn, you come back again. ”
