If this road doesn't work, then think of another way.

Nie Fei held Dan Fang in his hand and looked at it carefully. Two amorous flowers, three figs, two snow bamboo leaves, and a little white light stone. These kinds of things, put together, undoubtedly reacted, and this can be seen from the gelatinous substance. However, Nie Fei had no way of knowing what was happening, because he didn't even know what substance was.

This is different from what Nie Fei prepared before, such as the Spiritual Relief Herbal Liquid, the Sunflower Elixir, and the Detoxification Powder that was just refined a few days ago. For the things mentioned above, Nie Fei is just trying to extract the effective substances in them, strictly speaking, they do not involve reactions, that is, they do not change the structure of the substances. And this Yangyan Pill is different, its refining has indeed reacted and changed the structure of the substance, at least at the molecular level.

It is no wonder that it is said that the Yangyan Pill is difficult to refine, in this way, it is not only difficult for the alchemists of the current immortal cultivation realm to refine, but also for Nie Fei, a person with modern chemical knowledge, it is also very difficult.

Behind the Dan Fang is the refining method. Put amorous flowers, figs, snow bamboo leaves and white light stones into the Dan furnace, raise the furnace fire, and use the wood spirit qi to refine. This refining method is very common, basically all the Dan recipes, if they are exactly the same, put this herb, which herb into the Dan furnace, and then refine. It can be said that this has become a fixed cliché for alchemy, it doesn't matter if you write it or not, anyway, you put all kinds of herbs in a Dan furnace and stew it all the time.

At this time, Nie Fei suddenly had an idea, "Could it be that there is anything else to pay attention to in the order of putting the herbs?" Then, Nie Fei shook his head again, according to the analysis, there is nothing special about this order at all, several herbs are all put together in a Dan furnace, which one to put first, which one to put later, what is the difference?

For example, when refining and detoxifying, whether it is the two herbs that are put first or the two herbs that first release the fire poison of the double-edged grass, the effect is the same.

Nie Fei shook his head and sighed, "It seems that there is nothing to see in this Danfang." ”

......

At this moment, Lin Qiao sent a message to Nie Fei and asked Nie Fei to fan the flames for him. Lin Qiao, the great first-level alchemist of the Hundred Refining Sect, finally wanted to refine again after being silent for a while.

Nie Fei smiled bitterly, no matter how busy you are, Master's words have to be followed. Nie Fei had no choice but to temporarily put aside the matter of Yangyan Dan and go to Lin Qiao's alchemy to fan the flames.

This time refining and detoxification, Lin Qiao looked more solemn, and every action was extremely careful. Even the weight of the four herbs, he didn't know where to find a small scale, the scale was exactly the same, and then carefully put several herbs into the Dan furnace, as if the one put into the Dan furnace was not a medicinal herb, but an infant baby.

Nie Fei shook his head and sighed. Lin Qiao's serious attitude was right, but it was completely useless. Refining and detoxification, Lin Qiao didn't grasp the point at all, he just blindly scattered his energy, and the outcome was bound to be a failure.

Sure enough, twelve hours later, Lin Qiao opened the Dan furnace and took out the detoxification powder in the furnace, but he was dazed and disappointed again. This time, he failed again and refined another waste pill.

Lin Qiao held the waste pill and was dazed. Nie Fei noticed that Lin Qiao's nose was twitching constantly, and the corners of his mouth were trembling slightly, as if he was trying to endure something. Is Lin Qiao going to cry? Yes, looking at Lin Qiao's appearance, he obviously wants to cry. Nie Fei sighed, he quite understood Lin Qiao's feelings, Lin Qiao had paid so much, it could not be said that he did not work hard, but in the end, he only harvested a waste pill, no matter who it was, it was difficult to accept.

Who says that if you work hard, you will definitely reap the rewards? If you want to succeed, in addition to hard work, you must also find the right way. Otherwise, it will not only be thankless to do it with brute force, but it will also be difficult to succeed.

Nie Fei also had a lot of emotion in his heart, and he almost told Lin Qiao at this time that it was the correct way to refine the detoxification powder. But in the end, he held back. He knew what the consequences would be if he spoke out. That would undoubtedly expose himself. He can't afford this kind of result at present, and when he can, let's talk about it.

In the end, Lin Qiao's eyes were only red, and he didn't shed tears. He held the waste pill in his hand and sighed: "Hey, I don't know why, I can't refine it, I even strictly abide by the order in which the herbs are put into the Dan furnace, why can't I succeed?"

The speaker has no intention, but the listener has the intention. When Nie Fei heard this, his heart suddenly moved. He remembered the order of the four herbs on the Detoxification Powder Formula, which was to place the three herbs that could detoxify fire poison first, and then put in the double-edged grass. What if you put one antidote herb first, then put in the double-edged herb, and then put in the other two antidote herbs? Obviously, if you put it together, then there is no problem at all, but why is it not written like that in the Danfang?

Nie Fei suddenly realized that the order of this herb was not written casually, and there was still some truth in it. Detoxification is a proof of this. It is conceivable that if people are asked to put in the three antidote herbs first, and then put in the double-edged grass after the antidote herbs are completely dissolved, then the fire poison in the double-edged grass will be completely resolved. Although in this way, it may not be possible to refine the detoxification powder, but at least you will get some active ingredients of the detoxification powder. After that, relying on the different techniques of each alchemist, he got different grades of detoxification and dispersion. In this way, why Lin Qiao couldn't refine the detoxification powder, the answer was about to come out, it must be that he didn't completely detoxify the fire poison in the double-edged grass, and what he got was the waste pill.

At this time, it is obviously not the time to worry about Lin Qiao. Nie Fei thought again, can this kind of mystery of the detoxification and dispersion pill be applied to the beauty pill? As soon as he thought of this, Nie Fei couldn't help but be excited, and he immediately wanted to go back and test it according to his own ideas.

......

After watching Lin Qiao from discouragement and disappointment for a while, he became full of fighting spirit again, vowing to carry out the alchemy to the end, this inspirational process, Lin Qiao finally spoke and asked Nie Fei to go back.

Back at his residence, Nie Fei immediately took out the Dan Fang again. He first mixed a solution of amorous flowers and figs according to Danfang's writing. At this time, the solution is still in a layered state, and the two solutions do not react in any way. Nie Fei was about to add the snow bamboo leaf solution, but after thinking about it for a while, he didn't add it. He wanted to test whether the two solutions in the jade cup would react under the heated state.
