The two figures shuttled back and forth in the main hall here, the terrain was getting lower and lower, Chen Xuan had always felt that he was going down, and Chen Xuan's guess was right, that is, downward, because at this time, the hall master of the Dan Hall was moving forward and explaining some alchemy knowledge to Chen Xuan.

"Chen Xuan, I don't know if you are interested in alchemy, if you are interested, you might as well come to our Dan Hall to have a look, maybe you are still a genius of alchemy!" The hall master of the Dan Hall actually had the intention of wooing.

"Thank you for the kindness of the seniors, but the juniors don't know anything about alchemy, I'm afraid there will be jokes at that time!" Chen Xuan laughed at himself.

"It doesn't matter, this time for alchemy, you will stay by my side, you can familiarize yourself with it first, alchemy has three major requirements, as long as you master these three requirements, you can become a qualified alchemist!"

"What a request!" Chen Xuan immediately asked.

"One, hobby, this is a must, and it is also dominant, without this hobby, even if you have a good talent, you can't refine the best pill!"

Chen Xuan basically agreed with the first request of the Dantang Hall Master, whether it is cultivation or refining, don't diligently seek the spirit, without this spirit, it can only be empty in the end, in fact, alchemy is the same, you need to continue to persist and pursue.

"Second, the study of plants and trees, to be familiar with the medicinal properties of all elixirs, this is a very difficult task, no one dares to say that they know all the elixirs, but as long as they understand the characteristics of the elixir, they can refine the high-grade elixir!"

Chen Xuan also agreed with this, knowing the elixir is a necessary thing for an alchemist, although Chen Xuan also knows a lot of elixir types, but knowing and being familiar with the medicinal properties are not the same thing, refining the elixir cannot be a single elixir, it may take a lot of elixirs to be combined together to form.

It is very important to be familiar with pharmacology, what elixir and what elixir cannot be mixed together, what elixir can be combined with what elixir can refine what elixir, this is also the so-called Danfang, without Danfang, it is difficult for an alchemist to refine the elixir.

After explaining, the hall master of Dantang continued to make one last request.

"Three, that's the talent, the talent for understanding the spirit pill, the same alchemist, the same thing, but the things refined by two people are not necessarily the same, this is the talent that requires an alchemist, this kind of talent is not reflected in cultivation, some alchemists even only have the strength of the spirit martial realm, but the refined pill is not as good as the alchemist of the earth spirit realm!"

"What is talent!" was still a little incomprehensible to this Chen Xuan.

"Talent is to know the fire, pharmacology, all know everything, not only has a good understanding of the ingredients of the elixir, the same elixir, but the year is different, the control of the fire is naturally different, this needs to be controlled by the alchemist, ten years and twenty years of the elixir can not take a kind of fire to refine it, but not no alchemist can refine the elixir of each year, this is unrealistic, what is needed is talent, some powerful alchemy geniuses can find the law from it, so that the elixir does not waste a trace of consumption, can refine the best elixirThe hall master of the Dan Hall said carefully.

The two kept communicating, the hall master of the Dan Hall had no reservations, and told Chen Xuan about some things to pay attention to in alchemy one by one, and even took the trouble to explain many details, Chen Xuan walked while absorbing the field that he had never been involved in, and another door slowly opened towards Chen Xuan.

"We've arrived, this is my alchemy room!" the hall master of the Dan Hall pointed to a huge stone doorway.

Chen Xuan glanced at the surrounding environment and felt that the temperature here was much higher than the place he had just come, but he didn't think about it for himself.

"Let's go in!" After speaking, the stone gate slowly rose, and the hall master of the Dan Hall took the lead in entering, followed by Chen Xuan.

The environment inside was clear in Chen Xuan's eyes, this was the first time Chen Xuan had walked into the alchemist's room, and he saw a large Dan furnace that was one person tall erected in the middle of the room formed underground, and there were actually flames flying upwards below.

"You know the reason why the temperature here is higher than other places, it's that there is an underground fire vein here, and I built an alchemist on top of this fire vein to absorb the underground fire qi to refine the elixir!"

The surroundings are very simple, there is only one case with a lot of elixirs on it, these elixirs should be used when preparing to refine the elixir, Chen Xuan glanced around the Dan furnace, and saw that there were four legs under the Dan furnace. This furnace has four feet to support, and the hot flames are constantly spewing it underneath.

"Chen Xuan, tell me what elixir you want to refine, I also have a lot of elixirs here, as long as I have what I have, I can refine it for you!" said the hall master of the Dan Hall with a smile.

"Actually, it's like this, I'll come up with the elixir myself, I just want to ask the hall master to refine it for me, I don't know what kind of elixir these elixirs can refine, and I ask the hall master to take a look!"

After speaking, a large number of elixirs were taken out from Chen Xuan's hands, and these elixirs Chen Xuan was constantly absorbing the aura in the Heaven Swallowing Furnace without the slightest damage, and there was a delicate color on it, and the aura was compelling.

The hall master of the Dan Hall saw that Chen Xuan took out so many elixirs at one time, and there were a large number of 10,000-year elixirs among them, he was already shocked, and his eyes were open like a pair of copper bells, he really couldn't believe that this Chen Xuan had taken out so many elixirs at one time, "Isn't this going to rob the elixir garden of some major sect!"

"Hall Master, please see, what elixir can be refined from these elixirs!" Chen Xuan reminded as he looked at the Hall Master of Dan Hall who was shocked to be present.

"This, please let me take a look!" After speaking, the hall master of the Dan Hall actually took out Chen Xuan's elixirs and watched them one by one, each one was watched very carefully, and he didn't dare to have any negligence, because even if these elixirs were not necessarily able to come out with so many elixirs in addition to Tianbao Garden, he didn't dare to make any mistakes.

Half an hour passed quickly, and the hall master of the Dan Hall finally sorted out all the thousands of elixirs that Chen Xuan took out, basically divided them into three categories, Chen Xuan did not classify them, but at this time, the hall master of the Dan Hall classified all the elixirs, that is, what elixir is suitable for refining what elixir.

"Chen Xuan, can you tell me where you got these elixirs from? Except for the 10,000-year-old sect that can have such elixirs, the entire Northern Regions will not be able to produce so many elixirs at one time!" The hall master of the Dan Hall sighed for a while, he really couldn't believe that a holy son's hand could take out so many elixirs at one time.

"I can't answer this junior, there is one thing I can answer you, there is no problem with the origin of these elixirs, please rest assured that these elixirs are from one place, and this place is no longer available at this time, so it is meaningless for me not to say it!" Chen Xuan did not say the origin of the elixir.

First, these elixirs were obtained from the Demon Domain Forest, which he originally wanted to say, but after thinking about it, he killed his own fellow disciples in the Demon Domain Forest, and Chen Xuan didn't want to mention this matter again, lest anyone suspect him here.

Second, there are also some elixirs that come from the illusion realm of the Howling Moon Demon Lord on the Heavenly Demon Battlefield, this is even more impossible to say, if you say it, wouldn't it tell everyone that all the things left by the Howling Moon Demon Lord are in their own hands, and when the time comes, won't they have to attract the attention of many people, thinking about it, Chen Xuan still made up a reason to prevaricate.

"Since you don't say it, I won't ask, let me tell you, what elixir can be refined from these elixirs, but there are still a few elixirs that even I can't understand what elixir is, you take these back first!" The hall master of the Dan Hall pointed to the four or five elixirs that were placed aside.

"Senior, please say, what kind of pill can be refined!"

"Pure elixir, Yin Yang glazed pill, and Da Huan Dan, these elixirs can refine these three elixirs, if they are good, each can refine eight to ten pills, but there is still a lack of some auxiliary elixirs, but it doesn't matter, I have them here!" The hall master of the Dan Hall said all the elixirs that could be refined from these elixirs.
