"Lingzhu, everyone says that you are a genius in alchemy, but you can only refine some pills that others can also refine, so how can you show your talent? ”

"Disciples don't need proof. ”

The old man Suiyuan was slightly annoyed in his heart, why didn't this Lingzhu get in with oil and salt? He sneered: "Lingzhu, it's not nice to say something for the teacher, are you not unwilling to refine, but dare not refine? Are you afraid that after you can't refine yourself, others will laugh at you and say that you are a genius who is nothing more than that." Isn't it?"

In Lingzhu's eyes, there was a sudden flash of light, and after a while, Lingzhu said word by word: "Okay, I am refining, I want to see how difficult it is to refine the beauty pill, which is praised by the master as the most difficult to refine in the first-class elixir." ”

Only then did the old man with Sui Yuan put his mind at ease, this disciple, sometimes it is not good to talk well, and he has to take some means. "How about the 20th? After the 20th, can you refine the bamboo?"

"Twenty days, ten days is enough. With that, Lingzhu turned around and walked out of the refining hall without looking back.

The cold light flashed in the eyes of the old man Suiyuan, "This is also an alchemy wizard, otherwise...... Hum. ”

......

After Nie Fei came back from Yang Tianju, he planned to refine the Yangyan Pill, but he wanted to see what the difficulty of this was said to be the most difficult first-level pill to refine.

He took a look at the Dan Fang, and saw that it was written that the Yangyan Pill needed a total of three herbs, two amorous flowers, three figs, two snow bamboo leaves, and in addition, there was something called Bai Qingshi. Nie Fei guessed that this white light stone should not be a medicinal herb, but a mineral, because there is a stone character in the name, and in the refining method, it is clearly written that the white light stone should be ground into powder for use.

Sure enough, Nie Fei went to find an introduction to the white light stone, this is indeed a mineral, which can often be used in refining, mainly for the purpose of differentiating iron essence, but this kind of white light stone is rarely used in alchemy. Even if Nie Feidang had a question, refining the elixir, what was this white light stone for.

Nie Fei still followed the old method, but tried to find out what the three herbs of the Yangyan Pill were that played the main role, and then purified the herb, and the Yangyan Dan was also made.

He opened the Hundred Herbs Illustrated Book, and the information on these three herbs was complete, and it was not a rare herb. The function of amorous flowers is to calm and calm the nerves. Figs, which have no positive effect, are a kind of poisonous fruit, and immortal cultivators will have soil poison in their bodies after eating them by mistake. Snow bamboo leaves, which contain a small amount of cold attribute aura. As soon as he saw the information of these three herbs, Nie Fei was suddenly a little dumbfounded, from these materials, he couldn't see the slightest herb related to the effect of the beauty pill. It is no wonder that it is said that it is difficult to refine the beauty pill, which can be seen from this.

This road can't go on for the time being, Nie Fei is not dead-headed, and he has to think of other ways. However, he didn't know anything about the rules of the Immortal Cultivation Realm, and for a while, where did he go to figure out a way? He had to use his brain and think nonsense, but after all, it was also a guess out of thin air, and he didn't even have practical value at all.

In desperation, Nie Fei had no choice but to use the most stupid method first, which was to follow the method of alchemy in the Immortal Cultivation Realm, put several herbs together with the one called Bai Qingshi, and stew it again.

At that moment, Nie Fei went to Baicaotang again, and bought a lot of each herb. He didn't know how many times he had to try, but he had enough spare ones so he wouldn't have to make another trip.

This time Nie Fei went to Baicao Hall, and the guy inside, as soon as he saw Nie Fei's shadow, he trembled and trembled, and he no longer dared to ask Nie Fei to wait in line, but only asked Nie Fei to wait for a while, and then personally held the quantity ordered by Nie Fei and handed it to Nie Fei. For that guy's arrogant attitude, Nie Fei didn't feel it at all. In fact, this guy Nie Fei has never taken it to heart at all, like a disciple who belongs to the lowest level of the inner gate, Nie Fei has never looked at it.

After returning to his residence, Nie Fei set out to experiment according to the method of alchemy in the Immortal Cultivation Realm. He first mashed several herbs and prepared them into a solution, and then grinded the white light stone into a powder.

When a qiē was ready, Nie Fei mixed several solutions together, added white light stone powder to them, and then carefully observed the state of the mixed solutions. He found that after the solution of these herbs was mixed together, it was not soluble at all, and after only a moment of rest, the solution was divided into four layers, the bottom was those white light stone powder, and the top three layers of solution were the solutions of the three herbs in turn, which were incombusble and did not react at all.

Nie Fei picked up the fire in his palm and increased the temperature of the mixed solution. The temperature rose slowly, and finally, when a certain temperature was reached, several solutions were suddenly mixed together, and after only a moment, the delamination disappeared, and at the same time, the solution in the jade cup changed from watery to a colloidal state. Nie Fei stretched out his hand and touched it, the gum was full of elasticity, and there was a rubber-like feeling.

Although the solution reacted when Nie Fei warmed it, Nie Fei was sure that this was definitely not a beauty pill. This is a bit unscientific, the scientific statement is that there may be ingredients in it, but there must be other impurities, and the impact of these impurities on the beauty pill must be very fatal. This can be seen in two ways.

First, Yang Tianju has said more than once that the Yangyan Pill is very difficult to refine, and he has never seen the Yangyan Pill so far. However, Nie Fei's method is completely refined according to the method in the Dan Fang, that is to say, anyone can refine this gelatinous thing. If this is a beauty pill, then everyone can refine a beauty pill, which is not in line with the actual situation. Therefore, there is only one inference, that is, this gelatinous substance is definitely not a beauty pill.

Also, there is a foul smell from the gelatinous substance, which is disgusting. And the Dan Fang clearly says that the beauty pill will exude a fragrance, which is inconsistent with the facts.

Of course, among these gels, it is likely that there will be ingredients for the beauty pill, and Nie Fei can also find a way to separate the ingredients of the beauty pill among them, Nie Fei has also done this several times, and he should be able to do it. But the key problem is that Nie Fei is just guessing now, and he can't be sure, there must be an ingredient in it. Even if there were, Nie Fei had to first determine which ingredient was the effective substance of the beauty pill, so that he could come up with a way to separate it.

None of this can be determined, no matter how powerful Nie Fei is, it is impossible to separate the substance that does not know whether it exists or not.

"Could it be that this method is also a dead end?" Nie Fei thought.
