Time became very slow and slow, although he knew that he would soon be out of the Dan, but Cao Jing still couldn't suppress his excitement, but he still didn't need much control now, but his divine sense still controlled the Canghuo Water Lotus to adjust the flames, and it was also necessary to provide water spirit to the Canghuo Water Lotus in the middle, and transport the water spiritual power to the inside of the Dan furnace through the fire power of the Canghuo, and wash the impurities of the spiritual liquid or pill in the Dan furnace.

With the passage of time, the medicinal fragrance gradually came out of the Dan furnace, which was very subtle at the beginning, if it wasn't for Cao Jing who had been paying attention to the Dan furnace and focusing on this aspect, it was very likely that he would not be able to smell it, Cao Jing knew that this had reached the most critical moment of Cheng Dan, which was the precursor of the spiritual liquid beginning to condense and was about to solidify, and it could have a medicinal fragrance, at least it showed that Cao Jing's previous operations were not wrong, especially in terms of fire control.

The medicinal fragrance in the cave is getting stronger and stronger, and even Su Xue and Cang Yan, who are outside the cave to prevent the impact and harassment of demon beasts, can smell it, and the two of them can't help but shrug their noses vigorously, of course, you have to find their noses first! It's like a greedy child discovering food, but the two of them are indeed children.

After a full quarter of an hour, the medicinal fragrance in the cave is flourishing, and the rich medicinal fragrance is almost impossible to dissolve, of course, this is also because the cave is too small, the medicinal fragrance gathers, and it cannot be spread to cause such a strong medicinal fragrance.

When the Dan furnace began to tremble irregularly, the pill had already been refined, Cao Jing changed his gesture again, opened the Dan furnace, and saw four black pills lying inside, Cao Jing didn't feel ugly, and didn't care about the fire water lotus under the Dan furnace, but took out the four black black pills in the Dan furnace with a wave of his hand.

Looking at the four black pills in his hand, Cao Jing couldn't believe that this was the pill he had refined, first of all, the appearance of the pill was too ugly, if it was thrown to the ground, no one would dare to believe that at this time, compared with the pill refined by Lu Qianchao, alas, there is no comparison! The second is that Cao Jing still can't believe that he succeeded in becoming a pill for the first time, out of the pill, not to mention how the pill is, at least it succeeded, although Cao Jing saw it with his own eyes, and the pill was in his hand, but Cao Jing still couldn't believe it.

After experiencing the initial joy, Cao Jing quickly calmed down, no matter what, the elixir had been refined, however, the quality of the elixir was not flattering, and no one dared to ask for it like this. Then Cao Jing needs to find out the problem by himself and improve the quality.

Cao Jing first used the method recorded in the elixir Ziyu Jian to distinguish the situation of the four pills in his hand, and found that two of them were directly waste pills, or poison pills are more suitable, generally one to three layers of medicinal effect is called waste pills, and the pills below the efficacy of the three percent are harmful than good to eat, and there are too many erysipelas, which will have a counterproductive effect, and the poison pill as the name suggests is that almost all of the pills are poisonous or impurities or the efficacy is less than one percent, so the pills will be discarded or destroyed when they are out of the pill.

Among the four pills of Cao Jing, two of them were identified by Cao Jing and confirmed to be poison pills, and the other two, one of which was barely thirty percent of the efficacy, but in fact, it was less than three percent, and Cao Jing only thought that it was thirty percent, because the impurities of the pill itself from the water pill method were lower than those of the fire pill method, and according to the elixir estimate, when the novice first started, the pill refined by the water pill method was about five points to one percent lower than the impurities of the pill of the fire pill refining method. And the standard of the elixir is given by the Fire Yun Dan Method.

The third pill is barely thirty percent by the standard of the elixir, if Cao Jing uses the fire Yun Dan method, this one must be a waste pill, zuihou A pill has a medicinal effect of more than forty percent, but less than fifty percent, that is to say, Cao Jing became a pill for the first time, there are two poison pills, a waste pill, and an ordinary pill. Although the result was very unsatisfactory, Cao Jing was still very satisfied, after all, it was the first time for him to refine the pill, and he was not using the public's fire essence pill method.

Cao Jing decided to continue to work hard, but the two aspects of the efficacy, that is, the Cheng Dan rate and the physiognomy can only take into account one aspect now, Cao Jing decided to bring up the Cheng Dan rate first, and then find a way to change the face of the pill, so that the pill is more mellow and wishful.

Before refining the elixir for the second time, Cao Jing spent more than an hour carefully reading the experience of the elixir for beginners about the beginner's alchemy elixir again, and also referred to the experience of the fire refining method obtained from Lu Qianchao, which made Cao Jing gain a lot, after all, when he saw it before, Cao Jing did not have his own alchemy elixir, and he had no personal experience of the process, technique, and method, and now after he successfully refined it once, he had some experience and ideas about this process, and combined with the experience of the two, especially the experience of the elixir, Cao Jing had a feeling of sudden enlightenment, many things that I didn't understand before were directly practiced to Ruyi.

After thoroughly digesting all the experiences, and also had some opinions on how to improve the rate of becoming a pill, Cao Jing decided to start the second refining of the refinement, and it was also the refining and detoxification pill. Practicing again, Cao Jing seemed calm and confident, after all, with an experience, plus he had goods in his heart, Cao Jing also seemed full of confidence.

Generally speaking, the amount of elixir used in refining a furnace of elixir is the amount of ten elixirs, that is to say, theoretically, a furnace of elixir can be made into ten pills, and the reason why the amount of ten pills is also based on the choice, if the amount is too large, it is difficult for beginners to get started, and they cannot control so many elixirs, but if it is too little, it is difficult to become a pill, resulting in a large amount of elixir waste, and the amount of ten pills is the most appropriate amount after a large number of pharmacists have repeatedly tested shiyan certificates, neither more nor less.

The second time, it went very smoothly, three quarters of an hour less than half an hour, it has been completed, this time, the pills refined are still four, however, two of them have reached the ordinary pills, and the other two have more than two percent of the efficacy, which is a waste pill, but compared with the first time, there has been a great progress, especially the two ordinary pills have reached fifty percent of the efficacy, and when the efficacy reaches sixty percent, it is the intermediate pill, that is a qualitative improvement, Lu Qianchao is in his forties and fifty years old and can barely refine the detoxification pill into the middle-level pill, it can be seen that the alchemy pill is not easy or even difficult, not only his own innate conditions can be a pharmacist, but also to be talented.

For the first-grade elixir, Cao Jing didn't pay much attention to it, not only because Cao Jing had seen a lot of higher-grade elixirs, but also because the first-grade elixir in Cao Jing's hand was too easy to obtain, not to mention the elixir he had picked since the mountain, just after killing Lu Qianchao, there were too many elixirs stored in his storage bag, and Cao Jing didn't know the value of the first-grade elixir at all, and when he saw so many first-grade elixirs, he thought that the elixir was very ordinary, at least the first-grade elixir was very ordinary, in fact, Cao Jing would think so because it was too easy to get it, if other monks in the Qi refining period saw so many first-grade elixirs, they would probably go crazy, a first-grade elixir is equivalent to the food of ordinary mortals for most Qi Refining Stage cultivators, at least more than eighty percent of Qi Refining Stage cultivators, and they rely on this to earn gold coins to buy pills for cultivation!

In this way, for eight days, Cao Jing has been refining elixir in the cave, Cao Jing uses the low-grade elixir in his hand as usual as eating and drinking, with the continuous reduction of the elixir in his hand, the level of Cao Jingyun's alchemy elixir is getting higher and higher, two days ago, Cao Jingyun's detoxification pill and Huiling pill can easily reach about seventy percent of the medicinal effect, such an elixir can also be sold at a good price in Wuguancheng. Once the efficacy of the medicine breaks through eighty percent, it is a high-grade elixir, or a high-grade elixir, which is very rare, and it is difficult for even one out of ten people to achieve it, and maybe one out of fifty pharmacists can achieve it.

And in the next five days, Cao Jing concentrated on refining the Activation Pill, after all, Cao Jing's meridians have not fully recovered now, although it does not affect the refining of the pill, but in this Qinglong Mountain Range, it may encounter danger at any time, which will affect the strength of the play, and may be killed, so after the Detoxification Pill and the Huiling Pill have been refined into seventy percent of the pill, Cao Jing began to refine the Activation Pill, which has been quite effective in three days, and has been able to refine fifty percent of the medicinal effect, although there are only three or two of the pills in each furnace of pills, and more than fifty percent of them are only one each time, Cao Jing has already felt very satisfied, Cao Jing decided to wait until the time when the Activation Pill of seventy percent of the medicinal effect was refined, take Huoluo Pill to heal the injured meridians.

After three days again, it has been a month and a half since Cao Jing came to the Qinglong Mountain Range, and it has been nearly half a month since he learned the alchemy pill, to be exact, it is fourteen days, Cao Jing looked at a half-black and half-red pill in his hand, and his heart was excited, this is the effect of Cao Jingyun's refining has reached seventy percent of the active pill, and now Cao Jing has decided to take this pill so that he can repair the meridians as soon as possible and restore his strength.

These days, Cao Jing also gave Su Xue and Xiaoyan some of the pills they had refined, they didn't eat them at first, but the pills left by Lu Qianchao were eaten by them early, and they didn't want to eat the elixir anymore, so they had no choice but to eat Cao Jing's pills, after eating them once, they found that although the image of the pills refined by Cao Jingyun was not good-looking, in fact, there was no image at all, but they tasted much better than the pills refined by Lu Qianchao, so they didn't say anything anymore, but rushed to eat the pills refined by Cao Jingyun。
