Qingfeng pondered for a moment and said, "When I left my master, my cultivation was too low, and I didn't learn much, so I don't have much to teach you. In this way, I can accept you as an apprentice, but you don't want to leave the inheritance of Wangwu Mountain, you usually cultivate by yourself, if there are any problems, we will discuss them together, and learn from my Baicaotang. ”

Wu Laodao originally had this idea, but he was worried that he would worship in Baicaotang, but he still practiced the exercises of Wangwu Mountain, which caused Qingfeng to be dissatisfied. It turned out that Qingfeng didn't mind this, so he was completely relieved, and kowtowed to Qingfeng convincingly, and then stood up and met the senior brother Xuanjizi next to him. Chong Xuzi and Lingzhu also stepped forward to meet the newly baked uncle and uncle, and the formal apprenticeship ceremony had to be decided at a later date.

After everything, Qingfeng ordered: "I will not leave for the time being when I come back this time, but I will retreat on the mountain for two months and practice the Danshu well." ”

Practicing Danshu? That's great. Both Xuanjizi and Chongxuzi know that Qingfeng's Danshu is extremely high, and if Qingfeng can stay in the mountain for two months, it will be convenient to ask for advice in the future.

After everything was arranged, Qingfeng went back to the medicine valley by himself, and as soon as he arrived at the mouth of the medicine valley, the little red bird flew over sneakily, Qingfeng looked funny, and asked, "What's wrong with you like this?"

The little red bird whispered, "Shhhh ”

"What treasure?" Qingfeng was also curious.

The little red bird flew into the bushes next to it, took out a rag bag and flew over, and put it in Qingfeng's hand. Qingfeng looked at it, it seemed to be the storage bag of the ancestor of the Long family.

The ancestor of the Long family finally blew up the Jin Dan too powerful, Qingfeng thought that his storage bag was destroyed with the Jin Dan self-explosion, so he didn't look for it, but he didn't expect it to fall into the hands of the little red bird, this little red bird, the head is not big, and there are a lot of eyes.

Qingfeng smiled: "Don't you often go to Yamashita Elementary School to listen to the teacher's lectures?

The little red bird scratched his head and said, "I said it, but I think it's my master, I should hand it over to you first, and you will hand it over to the police uncle." ”

Qingfeng patted her head angrily and said, "You stupid bird, no one dares to ask for this thing even if you hand it over." I'll take a look at what's in there. ”

The owner of the storage bag has died, and the storage bag has become ownerless, and Qingfeng can open it by simply erasing the divine imprint imprinted on it by the original owner. Qingfeng opened the storage bag and rummaged through it, there were nothing too good, a low-grade spiritual weapon Pingshan Seal, a top-grade magic weapon soul bell, a demon pill of a wild wolf and demon beast, and some other miscellaneous things Qingfeng couldn't look at it at all.

But it's not bad, Baicaotang now has more disciples, and the spiritual weapons in his hands are really not enough, these few can be used to reward disciples. Qingfeng put the storage bag into his storage ring, touched the little red bird's little head and said, "This time you did a good job, I want to reward you well, and I will refine some pills for you to eat as jelly beans." ”

"Great, great. The little red bird leaped.

The little red bird had been living in the medicine valley before, but he didn't eat the elixirs and medicinal seeds that grew in the medicine valley, but they were all eaten raw, if Qingfeng helped him refine the elixir, it would be easier to digest and absorb it, so she would be so happy.

Needless to mention other trivial matters, Qingfeng is the highest-ranking ancestor of the Baicao Hall, so he doesn't have to worry about these things, he just needs to stay in the medicine valley and cultivate. When he was done with everything, Qingfeng called Xuan Jizi, Wu Laodao and Chong Xuzi over to test the alchemy of the three of them.

The first to be tested by Xuanjizi. Xuanjizi took out a magic alchemy furnace, prepared all the materials needed according to his own habits, and then released the Dan fire into the alchemy furnace. After the preheating is completed, Xuanjizi follows the alchemy steps, puts in various medicinal materials and materials, and begins to refine carefully. An hour later, after the elixir was refined, Xuanjizi took out five pills from the alchemy furnace and handed them to Qingfeng's hand.

Qingfeng looked at it, these were five Qi Transformation Pills, two of them were dark brown, the other two were blue-brown, and the remaining one was no longer brown, almost reaching the color of complete dark blue. It's not bad, it seems that Xuanjizi has also worked the pill during this time.

Qingfeng commented: "There are a total of five Cheng Dan, two of which are low-grade Qi Dan, two are medium-grade Qi Dan, and one barely meets the requirements of the high-grade Qi Dan." On the one hand, it is the reason why you have improved your cultivation and mastered the heat, and on the other hand, it is also the reason why you have practiced diligently during this period of time and have not slackened. ”

Hearing Qingfeng's praise, Xuanjizi couldn't help but show a smug look, this period of hard work was finally not in vain.

Qingfeng continued: "But if such an elixir is refined by someone else outside, it is understandable, if it is refined by our Baicao Hall, I will criticize it." ”

Unexpectedly, the master first raised and then suppressed, and Xuan Jizi listened with a bitter face.

Qingfeng said: "A total of ten pills of pills of materials at a time are put in the furnace, but you only refine five pills, wasting the materials of five pills, this is one; you are already a monk in the Jindan stage, but you still use the pills of the Qi Transformation Stage to practice, the Danshu can't keep up with the cultivation, and the second is that; the five pills of the Qi Pill that you have refined are actually four of the middle grade and the lower grade, and only one of them barely reaches the top grade, and the Danshu is too poor, and the third is the third. Therefore, Danshu like you can only barely be regarded as alchemy, and you can't be called a good alchemist. ”

Wu Laodao secretly said to himself, this Qingfeng Master's requirements are too strict, isn't it an alchemist with such a high success rate?

After commenting on the Xuanjizi, and then tried by Wu Laodao, the same Dan furnace, the same material, the difference is that Wu Lao Dao's cultivation is not enough to have Dan fire, so he can only use mortal fire to refine Dan. Wu Laodao spent more than an hour, and in the end he only practiced a black and gray thing. Fortunately, he said hello in advance, saying that he had no talent for alchemy, and had studied Danshu for a period of time, but he had no achievements, and then he stopped practicing.

Qingfeng frowned when he saw it, and said helplessly: "It seems that you really don't have alchemy talent, forget it, I won't force it, you better be busy with other things." ”

Chong Xuzi was the last to be tested, because Qingfeng commented on Xuan Jizi, saying that his Dan technique could not keep up with his cultivation, so Chong Xuzi did not use the Qi Cultivation Pill to practice, and like Xuan Jizi and Wu Laodao, Chong Xuzi also refined the Qi Pill.

Chong Xuzi's techniques were all taught by Xuanjizi, so it was similar to Xuanjizi, and he also used the magic alchemy furnace, using the same ten parts of the Qi Pill material, and like Wu Laodao, he also used mortal fire. It was also a refining process that lasted more than an hour, and finally took out two pills from the alchemy furnace.

Qingfeng looked at the pill refined by Chong Xuzi, shook his head and said, "Ten materials refine two pills, and they are all low-grade Qi Transformation Pills, which is really too bad for medicinal materials." However, you have just entered the gas transformation period for a short time, and it is understandable. ”

Qingfeng looked at the two of them and said: "It seems that the signboard of our Baicaotang alchemy is worrying, so let's do it, you will practice Danshu with me for the next two months from today, and I don't need your alchemy level to be high, as long as you can see it and don't lose the face of our Baicaotang." ”

Xuanjizi and Chongxuzi nodded yes.

Qingfeng continued: "Let me first tell you why the success rate of alchemy is so low. To refine the elixir, the first thing you need is the formula, the level of the elixir is different, the formula is also different, the higher the level of the elixir, the more complex the formula, the more difficult it is to understand. For example, Lian Qi Dan and Hua Qi Dan, these two kinds of pills have their own requirements for the type, dosage, year, number of auxiliary drugs, addition time, heat, refining method, etc. ”

"Many people don't understand, since you have a formula, just practice it, what's so difficult? In fact, the difficulty is still to come, this is the second point I want to say, the use of medicinal materials. The formula only gives the standard configuration of various medicinal materials, but in fact, the medicinal materials are not as standard as the formula is labeled. For example, a hundred-year-old medicinal herb may actually have grown for one hundred and five years, or it may have grown for ninety-nine years and a few months, and the subtle difference is not visible; even if it is a standard hundred years, it may have grown in the dense forests in the east, or it may have grown in the mountains in the west, and there are still differences in the region; even if it is the same year and the same region, then the environment in which it grows may be different, perhaps it grows in a relatively barren place on dry land, or it may grow in a more fertile place. If you subdivide it further, there is also the age of its growth, some of which suffered more natural damage when they were grown, and some of which have been safe and secure for so many years, as well as the different picking methods, different ways of blooming, different storage times, and different differences in the loss of medicinal power, etc. ”

"Since there are so many external influences, of course, the medicinal power contained in each medicinal herb is also different. The difference is a thousand miles, each herb is slightly different from the formula, and in the end, can there be no difference in the elixir that is practiced together? Can the success rate of the elixir be high? These are not the ones that can be marked on the formula, but this really affects the quality of the elixir, and many people don't know this reason, so refining the elixir always fails. ”

"In addition to medicinal materials, there are also refining methods and fire methods, let's talk about these later, or continue to talk about the problem of medicinal materials. Knowing the difference between medicinal materials can solve the problem of the low success rate of pills? Of course, not. At this time, it is necessary to watch more and practice more, grasp the characteristics of each medicinal material, observe the medicinal power of each medicinal material, fine-tune the configuration ratio of various medicinal materials in the elixir formula, and adjust them to the best mix ratio. ”

Chong Xuzi interrupted Qingfeng's explanation and said: "Master, more than ten years ago, I went down the mountain to practice, and I once went to a construction site, and they used the word mix ratio when making concrete. The strength of concrete has a fixed mix ratio, that is, the ratio of stone, sand, cement and water, but due to the difference in the materials supplied, such as the stone is not pure, it contains crushed sand, or the sand is wet, and it contains water. At this time, the laboratory should reduce the amount of sand according to the crushed sand contained in the stone, and reduce the amount of water according to the amount of water in the sand, so as to adjust the optimal mix ratio. Isn't this the same as what Master Ancestor said just now?"
