The Yun family's Danfang is just a very inconspicuous small house on the surface. Pen ~ fun ~ pavilion www.biquge.info but after Qin Yuxuan walked in, he found that there was a cave inside, and there was a long underground passage in the room. Access to a sprawling basement. According to Yun Yun, that was the real Dan room, and there were a total of six separate alchemy rooms in it.

"It seems that these alchemy rooms are set up underground, most of them to facilitate the fire of the earth. Qin Yuxuan said secretly as he walked.

When he walked to the hall of the Danfang, he found that there was only a thin old man sitting on a chair to guard it. And what made him cry and laugh a little was that this thin old man was still dozing.

And he can't see the realm of this old man at all, although his image is sloppy, but his strength is obviously not weak.

"This senior, I want to come to alchemy, can you please help me open an alchemy room?" Qin Yuxuan first asked in a low voice, and then saw that the old man was still not awake, so he had to shout loudly.

The thin old man woke up from his sleep at this time, he opened his eyes and glanced at Qin Yuxuan for a moment, and after looking at his cultivation and the clothes of the side disciples he was wearing, Fang said with a surprised face: "I'm not mistaken! You, a side disciple of the second layer of the Yuan Shen Stage, also want to come to alchemy? Shouldn't it be a sudden whim?"

Qin Yuxuan frowned and said, "Senior, isn't there a rule in the clan that side disciples are not allowed to use the Danfang?"

"Of course there can't be such a rule. It's just that this alchemy depends on talent, and there are a lot of medicinal herbs consumed in the learning process, the old man thinks, I'm afraid you can't afford the spirit stones you need!" The old man was obviously very suspicious.

"Senior, the kid just wants to try if he has alchemy talent, so he prepared a few materials to try it, of course it is best to refine it, and if he can't refine it, forget it, I'll continue to concentrate on cultivating spells!" Qin Yuxuan said with a sincere face.

"Okay! Anyway, the alchemy room has been empty for a long time, and it will only be opened when the guest alchemist comes to alchemy. You hand over a spirit stone, and then go in and try it! Except for the No. 1 alchemy room, which is reserved for him and you can't enter, you can enter the other five alchemy rooms at will!" the old man finally relented.

Qin Yuxuan nodded, but took out five spirit stones from his pocket and handed them over.

He showed a smile and said, "Senior, the kid is relatively poor, and he doesn't have many spirit stones. Except for the spirit stone that rented the alchemy room, the other four pieces are all filial to your old man. I've never used these five alchemy rooms, and I don't know which one is better. I don't know if you can give me some pointers?"

The old man was also stunned for a moment when he saw this, and then he smiled and said, "Boy, it seems that you are quite good at being a person! The old man will also remind you: there are still differences between the several alchemy rooms in this Dan room." Except for the alchemy room in room No. 1, among the other five alchemy rooms, the earth fire in room No. 5 is the most stable, you can go there and try alchemy!"

With that, he opened the prohibition in the alchemy room and handed him a key at the same time.

Qin Yuxuan glanced at it, and saw that the key was engraved with the word "five", and there was a slight coolness in his hand. He secretly thought that it was worth it for him to spend an extra four spirit stones.

So, after thanking the old man who was guarding the door, he strode to the door of the fifth alchemy room, then opened the door with the key and walked in.

……

After entering the room, Qin Yuxuan carefully looked at the situation in the alchemy room, and saw that in the No. 5 alchemy room, there was a small bed made of bluestone, with a quilt cover and pillows on it, and in front of the small bed, there was a green futon, which seemed to be used by alchemists when they meditated and rested.

The most striking thing is that in the center of the Dan room, there is a three-foot-high, chimney-like hollow pillar with a handle on it.

Qin Yuxuan tried to rotate the handle, only to see a bright red flame suddenly erupt from the top of the pillar, which was extremely hot and startled him.

After a while, Qin Yuxuan calmed down and tried to turn the handle again.

Only then did he realize that turning left is to increase the firepower, and turning to the right is to reduce the firepower, which is very convenient.

After mastering this decision, Qin Yuxuan took out the Jade Yellow Pill Pill Pill Formula he got from Cai Jin, as well as the "Alchemy Experience", and began to study it carefully......

After reading the booklet of alchemy, Qin Yuxuan finally had a certain understanding of the way of alchemy. The main key to refining the pill lies in the control of the heat during the alchemy and when to open the furnace to extract the pill.

And the items he thought were more important, such as the combination of various herb raw materials and the proportion of the number of elixirs, had already been clearly stated on the Danfang, and he only needed to match them according to the introduction of the Danfang. He didn't have to think about it at all.

Of course, the experience of alchemy also shows that when configuring the raw materials of the elixir, it is possible to appropriately increase or decrease the materials. However, it must be in accordance with the fixed proportion required by the Dan Fang, so that the number of Dan can be controlled at one time......

It's just that the more materials there are, the more difficult it is for alchemists to control the heat and opening time. It's easier said than done!

According to the statement in the jade slip of "Alchemy Experience", just accurately controlling the heat of the furnace, grasping the opening time of the furnace, and calculating the best time to produce the furnace, these three major problems do not know how many alchemy masters have been stumped.

Generally, the success rate of the first alchemy of a monk in the Yuan Shen stage is almost less than one percent, and even if a monk who has been specially trained and has a certain alchemy talent, the probability of success will not exceed 10,000 within half a year of starting alchemy.

Of course, after several years of practice, after stacking up with countless spirit herbs and elixirs, an ordinary alchemist still had a one-third success rate of refining low-grade elixirs.

It's just that this is limited to refining the pills he is familiar with, and if he changes the pills he hasn't refined, I'm afraid the success rate is still very low.

Therefore, whether an elixir can be successfully refined depends on whether the alchemist has rich experience. The more alchemists who have alchemized more times, the greater the chance of becoming a pill. Therefore, alchemists, refiners, and talisman makers have become the three most money-burning professions in the immortal cultivation world. Of course, they are also the three most popular professions.

After Qin Yuxuan learned about these situations from Cai Jin's booklet "Alchemy Experience", his heart was half cold. He secretly thought: he is a rookie who has never refined any pills, although he has more than a dozen jade pill materials at the moment. But with his own alchemy level, I'm afraid that I won't be able to refine a single pill even if I waste it all.

However, now that the spirit stones for renting the alchemy room have been handed over, even if it is to catch the ducks on the shelves, Qin Yuxuan will have to give it a try.

So, after taking a deep breath, he took out the Purple Gold Danding from his storage bag and placed it on the top of the hollow pillar......
