"Your cave mansion? oh yes, it's been so long since you entered Lingshan, you must have your own cave mansion, whether it's good or not, I can just go and visit it, hehehe", Huang Hua suddenly felt a little inexplicably excited in his heart.

"Where is your cave? It's not far away, are there any monsters nearby?", bored during the flight, Huang Hua began to feel a little Tang monk.

Zou Shuniang's face suddenly turned red, "Are you annoyed, why are you talking so much?

The two flew for nearly a day and a night before they reached a high mountain at noon the next day.

"Huh, isn't this the active volcano? I seem to have met you here?", Huang Hua looked at the half-green and half-scorched mountain in front of him, and suddenly remembered the situation when he met Zou Shuniang in the first place.

"Hmph", Zou Shuniang blushed and glanced at Huang Hua again, and then flew towards a certain place on the mountainside on the sunny side of the volcano.

Zou Shuniang's cave is much larger than Huanghua's cave, and it is also a naturally formed cave, although there is also only one space, but Zou Shuniang used some branches and vines to simply separate the space, divided into several areas of different sizes, but the strange thing is that at the innermost end of this cave, there is a circular passage that has been artificially dug out, leading to the depths of the volcano.

"Huh, why is there a secret passage in your cave?", Huang Hua was very curious about this passage.

"Let me open your eyes, do you think it will take two years for this girl to hit the bottleneck of the knot pill from the later stage? If it weren't for the fact that I hadn't taken the spiritual liquid and Tang pear flower, I would have already gotten out of the mountain, so in order to pass the time, I have been improving my alchemy level here", Zou Shuniang directly entered the passage after speaking.

Huang Hua followed Zou Shuniang in the passage for about a pillar of incense before he reached the end of the passage, but what Huang Hua didn't expect was that the end of the passage was just a closed stone room.

"Huh, why is it a stone room, what about the earth fire you are talking about?", Huang Hua found that in addition to a strange formation pattern on the ground of the stone room, there were only a few alchemy furnaces of different sizes and some bottles and jars, and nothing else.

"Do you really not even know this kind of common sense?God, who are you?Are you really just a casual cultivator?", Zou Shuniang began to doubt Huang Hua's identity again.

"Zou Daoyou, I'll tell you again at the end, I'm just a casual cultivator, I don't understand a lot of things, if you don't want to say it, you can not say it, but please don't talk to me in this tone", Huang Hua was a little unhappy, he didn't want to be ridiculed every time.

"Eh, I'm sorry, I'm sorry, I'm not looking down on loose cultivation, I just think you're very mysterious, okay, don't talk about this, it's actually like this", Zou Shuniang saw that Huang Hua's face was very ugly, so she hurriedly explained.

"That's the case, the spiritual fire used for alchemy, whether it is a heavenly fire, an earth fire, or a Dan fire, cannot be used directly, and it must be controlled with the help of a special formation to control the size and duration of its firepower, so you can't see the open flame, so let's do it, I still have some ordinary materials, I'll show you first", Zou Shuniang finished speaking, took out several piles of common alchemy materials from the storage bracelet and put them in front of her, and then sat cross-legged in front of the formation pattern on the ground of the stone room.

"The first step, raise the fire furnace", Zou Shuniang stretched out his hand to the magic circle on the ground to shoot a blue light, as soon as the blue light entered the magic circle, the ground covered by the entire magic circle flashed red, and then several flames sprayed up from the ground, Zou Shuniang waved her hand, and a Dan furnace on the ground rose into the air and flew into the flames above the formation.

"The second step, material purification", Zou Shuniang rotated the Dan furnace in the flames and heated it thoroughly, waved her hand and threw one of the bunch of medicinal materials in front of her into the Dan furnace, the Dan furnace opened the lid in the air by itself, and closed it by itself after the materials were put into the furnace.

"This is a key step, first of all, you must be familiar with the properties of the material, understand the purification time of each material, and secondly, you must master the heat of refining, otherwise the medicinal effect of the material will either not be fully stimulated, or it will be over-excited and cause failure", Zou Shuniang said while driving the Dan furnace to pour the purified liquid into a small jar next to it, and at the same time waved his hand to put another material into the furnace, after the second material was purified, Zou Shuniang poured it into another small jar next to it.

"The third step, medicinal effect synthesis", Zou Shuniang purified all the ordinary materials in front of her and poured them into different small jars, and then began to synthesize and refine.

"This is also a key step, the efficacy of each material is different, it needs to be added at a specific time, I am refining the 'Huanglong Dan' used in the refining period, first put in the purified main drug 'Rehmannia Essence', and then add 'Ma Long Root' after the efficacy is stimulated to seventy percent, and after the two medicinal effects are synthesized and stimulated to ninety percent, then quickly add other excipients", Zou Shuniang was a little serious.

"The last step, condense into Dan", after Zou Shuniang put all the purified medicinal liquid into the Dan furnace, she began to increase the urging of the temperature of the earth fire, "This step is the most critical step in all the steps, either become Dan or fail", Zou Shuniang closed her eyes after speaking, and began to feel the changes in the medicinal materials in the Dan furnace with her divine thoughts.

"Open", with Zou Shuniang's coquettish shout, the fire in the array was extinguished instantly, and the Dan furnace suspended in mid-air also opened the lid out of thin air at the same time, and a thick medicinal fragrance came from the Dan furnace.

The Dan furnace slowly landed on the ground, and Zou Shuniang also stood up from the ground sweating profusely, "It's okay, this furnace 'Huanglong Dan' is good, just take it as a gift from me", Zou Shuniang took out a small bottle, put away the furnace pills and handed it to Huang Hua.

"Wow, it turns out that alchemy is so simple, you can refine a furnace in two or three hours, no wonder your Qingyun Sect can be so rich just by relying on alchemy", Huang Hua couldn't help but be a little surprised when he saw that Zou Shuniang didn't take long to refine a furnace of "Huanglong Dan".

"Simple? Do you know how long it took me to learn this 'Huanglong Dan' just by learning? If you don't get your hands on it yourself to familiarize yourself with the efficacy properties of each medicinal herb, as well as the mastery of the heat, you will have to waste countless materials and years of time on this purification alone, and it is easy to say, hum, that's okay, then you can try it."

Zou Shuniang is already a mid-level alchemist, and she didn't know how many furnaces of "Huanglong Dan" she had refined in the sect before, and it was naturally simple and easy for her to refine it, but let Huang Hua refine it, that was another matter.

The next period of time, that is the beginning of Huang Hua's nightmare, it seems easy, but once he gets started, Huang Hua knows that he is very wrong, although Huang Hua is the acquired spiritual root is talented, and he has also collected a lot of ordinary alchemy materials from other places before, but this "Huanglong Dan" alone took Huang Hua more than a month of time and most of the materials, and it was not easy to refine successfully.

But in this month's time, Huang Hua used up all the ordinary alchemy materials on himself and Zou Shuniang, and in order to continue to learn alchemy, Zou Shuniang and Huang Hua had to look for elixir that could be used for alchemy in the spiritual mountain.

Lingshan is very large, in addition to many rare thousand-year-old elixirs in the mountain, there are naturally many common elixirs that are still young, so in the following time, Huang Hua and Zou Shuniang began to go through the mountains and mountains to look for usable elixirs during the day, and at night they both returned to the Volcanic Cave Mansion to continue learning alchemy.

In just two months, the footprints of the two have almost traveled all over the entire Lingshan, every mountain stream, every jungle and mountain, leaving the laughter of the two, these two months seem to be hard work, but it is a rare good time.

"Hey, I said Zou Xiaomei, you said that the two of us don't look like the legendary double cultivation partners during this time, we are a man and a woman who practice in seclusion in this spiritual mountain, one does not have to worry about being disturbed, and the other does not have to worry about the world, every day to collect medicine and alchemy and fly in both nights, it is really rare and leisurely, if I can always be like this, even if I stay in the mountains forever, I am willing", Huang Hua and Zou Shuniang went to get the spiritual liquid on the flight, and suddenly sent out a burst of emotion to Zou Shuniang beside him.

"What, where did I double cultivate with you, don't talk nonsense", Zou Shuniang's face suddenly turned crimson when she heard this, and she quickly denied it.

"Where did I talk nonsense? Originally, you see that there is no one else in this spiritual mountain, just the two of us, we collect medicine and alchemy together, meditate and cultivate together, isn't this considered double cultivation?", Huang Hua was a little puzzled by Zou Shuniang's denial.

"Ahh , do you really don't know or don't know?", Zou Shuniang said halfway, suddenly stopped the flying magic weapon, and turned her head to look at Huang Hua with wide eyes.

"I told you, I'm really a casual cultivator, there are a lot of things I don't know, if I say something wrong, you can correct it and tell me, but please stop doubting it?", Huang Hua didn't know where he said something wrong, and felt a little depressed.

"Well, okay, I've also obeyed you, and in our current situation, at most, it's called group cultivation, not double cultivation, and double cultivation means, it means...... , refers to the kind of thing between men and women", Zou Shuniang finished speaking, and flew away with a red face with a magic urge.

"Oh...... , Cut, I thought it was a big deal, it turns out that double cultivation refers to the same room, what's so shy about this, cut", Huang Hua smiled, and then followed with a flying magic weapon.

Since the excipients of many pills are basically the same, Huang Hua's progress has accelerated a lot when he learned to refine other pills later, not only learned the refining methods of several other commonly used pills, but also slowly mastered some of the tricks of alchemy.

In fact, the process of alchemy is the same, and the biggest difference and difficulty is that because the medicinal effects and ages of the medicinal materials are different, it is necessary to accurately grasp the refining time and heat, and these have nothing to do with talent, and can only be accumulated by continuous refining.
