I saw Bu Yanyun repeating the action just now, this time she insisted on about ten breaths, and the black smoke from the Dan furnace floated out again, only to hear her say: "To learn alchemy, you must have patience, not afraid of failure, you are afraid of not daring to do it, you wait, I will come again." ”

When Bu Yanyun took out the first-grade top-grade spirit grass again and again, Nie Wushuang stepped forward and said, "Hmm, Senior Sister Bu, is this alchemy going through this process......? I've changed a lot of low-grade spirit stones......"

Bu Yanyun sighed, retreated to the wooden table on the side, sat down dejectedly, and said, "Master said that alchemy is divided into four steps: purification, melting, hedan, and collecting dan. The requirement of purification is to extract the medicinal power in the spirit grass, and the requirement of melting liquid is the ratio and heat that should be mastered when the medicinal power is fused. I can't do this first step of purification, hey!"

Nie Wushuang looked at her appearance, and felt sorry for this girl, walked quickly to the head of the bed, turned out three or four first-grade top-grade spiritual grasses from under the bed, walked to Bu Yanyun's side and handed them over: "Senior Sister Bu, I have a lot of spiritual grasses here, you can take them all, and study alchemy hard." Speaking of this, Nie Wushuang's face showed excitement and said, "I heard that the pill is precious, it is said that one spirit pill can be sold for ten low-grade spirit stones." If you use the Gathering Spirit Pill to cultivate, you can instantly gather the aura in the air for three days and three nights. ”

Bu Yanyun squinted at Nie Wushuang, and said with a somewhat lost face: "Hey, forget it, it is estimated that I am a genius cultivator, but I am not a genius Dan Master." ”

Nie Wushuang said: "Senior Sister Bu, since your master said that you are talented, what he said must not be wrong." Look at me, you said that I was going to the ghost clan to find my mother's soul, isn't it difficult? But did I say that I would give up? As long as I am still cultivating and I still have a breath, I must go and find my mother's soul and help her be reborn. ”

Bu Yanyun breathed a long sigh of relief and said: "Well, that's right, yes, your matter is much more difficult than what happened to me, since my master said that I have talent, then I must have it, forget it, I guess I didn't sleep well today, I will go back to study more with my master first, and I will teach you another day." As he spoke, Bu Yanyun took out two books from his arms, threw them on the wooden table in front of him, and said: "Here one is the Dan Fang, and the other is the alchemy method, steps and alchemy annotations given to me by the master, basically covering all the Yipin Dan, which could not be given to you originally, these two books were copied by me, and you take them to ponder and ponder by yourself, so as not to understand anything in the foundation building period in the future." Okay, I went down the mountain, and the master said that my realm of building the first order of the foundation has just been stabilized, and I have to think more about it, you take care of yourself, Senior Brother Mo, I will solve it for you. ”

Nie Wushuang said: "Senior Sister Bu, since your master told you to stabilize your realm, you should listen to him well, this learning alchemy is not a matter of one or two days, don't worry." ”

Bu Yanyun nodded and said, "Well, this Dan furnace and flame stone will be placed here for you, I may come back one day." After speaking, she walked quickly to the door, opened the wooden door and was about to go out, turned her head to look at Nie Wushuang and said, "Remember to wear more clothes to sleep at night in the future...... That one...... I don't know when I'll come again......" After speaking, his face flushed, and he disappeared in the doorway.

Nie Wushuang looked at the disappearing figure of Buyanyun, and was in a daze for a long time before he came back to his senses and said to himself, "When will you come again?"

Lying back on the bed, Nie Wushuang did not undress, his eyes swept to the door from time to time, expecting Bu Yanyun to suddenly come back, after a while, Bu Yanyun never appeared again, but Nie Wushuang was made by her to think of flying, and could no longer sleep, so he got up, and under the light of the oil lamp, took the two books she left behind and began to look through them, one is a pure Dan Fang, just explaining what spirit grass is needed to refine what Dan, what is the ratio of spirit grass to each other, the purity of the medicine of the spirit grass itself is best above a few percent, the role of the best spirit grass, etc., the other one, how to make alchemy, the alchemy steps described in it, methods, annotations, and so on are all very detailed.

"Hmm, why don't I try it myself?" Nie Wushuang looked at it for a long time, and suddenly said to himself: "In this way, I will try it with a top-grade first-class herb, and have a good experience of what is going on in this introduction to the steps of alchemy, such as purification, melting, Hedan, and Dancheng." ”

Nie Wushuang said, he didn't delay any longer, rushed to the side of the bed and took out a first-grade spirit grass, and then learned the way of walking smoke and clouds, and threw the flame stone at the bottom of the Dan furnace, with a little aura, the flame stone floated out of the blue flame, he quickly wiped the lid of the Dan furnace with his left hand, and threw the spirit grass into the Dan furnace.

At this time, in Nie Wushuang's chaotic eyes, a trace of chaotic qi quickly rushed from the center of his eyebrows to Nie Wushuang's palms, and that trace of chaotic qi escaped from the palms of Nie Wushuang's hands, and when he climbed up the outer wall of the Dan furnace, suddenly he found that his eyes were caught in a white mist, a chaos, if it weren't for the palms of his hands still pressing on the wall of the Dan furnace, Nie Wushuang would even wonder if he was doing the matter of refining the spirit grass.

Except for a chaotic white mist, he couldn't see anything inside or outside the Dan furnace at all, and all he saw was chaos.

Nie Wushuang felt strange in his heart, he tried to use his eyes and mind to explore the situation in this Dan furnace, but no matter what effort he made, it seemed to be in vain.

In addition to the inside of the Dan Furnace, even the outer wall of the Dan Furnace, including his palm, was also in chaos, and Nie Wushuang could only see the white mist wrapping in it, and his flesh-red wrist was hanging in the air.

"What's going on?" When Nie Wushuang was surprised, he suddenly felt the chaotic qi in his palms suddenly rush into the Dan furnace, and the impurities in several spirit grasses were separated by the chaotic qi on his palms through the Dan furnace, just like a cow in cooking, all the impurities were cut out of the herb itself at the fastest speed, and the black particles turned by those impurities disappeared without a trace in an instant under the high temperature of the Dan furnace.

As several spirit grasses that shimmered with golden light floated in the center of the Dan Furnace one by one, Nie Wushuang himself was taken aback.

Nie Wushuang couldn't see the situation inside and outside the Dan Furnace at all, but what surprised him was that the situation inside and outside the Dan Furnace didn't need to be seen by himself at all, purely through that trace of chaotic qi, he could completely perceive any movement inside the Dan Furnace, which was clearer than what he saw with his own eyes.

Extinguishing the flame stone with one hand, Nie Wushuang withdrew the chaotic qi and uncovered the Dan Furnace, only then did he see that the pale green liquid at the confluence of the Dan Furnace Dan Wall was flickering with a little light, his eyes were staring straight at it, and he said to himself in surprise: "It's so simple?"

At the moment, Nie Wushuang thought about it for a long time, and finally determined one thing, that is, the purification of this spirit grass, in fact, has little to do with himself, he did not do it in the way Bu Yanyun said, but the three life recipes worked, the chaotic qi escaped from the chaotic eyes, and after entering the palms, everything seemed to be controlled by himself, and when the chaotic qi entered the Dan furnace, the things that followed seemed to be the chaotic qi was the master, and Nie Wushuang himself became a spectator, or that kind of eyes, The viewer who can't see clearly with his thoughts, and relies entirely on his perception and feelings.

After Nie Wushuang thought about the reason for refining the spirit grass, he couldn't help but say to himself: "Senior Sister Bu is such a genius disciple, and she didn't make it for half a night, but I'm lucky with shit, basically I don't have to work to do the first step of alchemy Spirit Grass purification; Nie Wushuang didn't expect that such a difficult thing to do in Buyanyun would become so easy in his own hands, thinking about it, Nie Wushuang grinned happily.

After laughing, he looked out the window, at this time the east was already white, thinking that he was going to send tea to the hall master today, Nie Wushuang cleaned up the house, and after tidying up, the sky was already bright, and he was about to get the tea that had already been prepared, but he heard the news from the deacon at the entrance of the hall to transmit the sound of Yu Jian: "Nie Wushuang, the hall master is going to meet the important guests in the Cedar Hall today, you go to the side hall to prepare first, and when the guests enter, you will serve spiritual tea." ”

"Important guests?" Nie Wushuang didn't dare to delay, and after tidying up himself again, he hurriedly rushed to the side hall next to the Cedar Hall, at this time, it was only early in the morning, the dew outside the house was dotted, and the sun was shining warmly, which made people feel lazy.

In the side hall, Nie Wushuang prepared spiritual tea and spiritual spring water, and began to wait for the appearance of the guests in the main hall.

After waiting for about a stick of incense, Nie Wushuang suddenly heard footsteps outside, followed by the sound of people greeting each other, he hurriedly leaned out, and suddenly looked at it, and found that there were three people at the door of the main hall greetings, so he hurriedly returned to the tea room in the side hall, began to boil water, and prepared spiritual tea for three people.
