On the surface of the Yun family's Dan's house, it is just a very inconspicuous little house.But after Qin Yuxuan walked in, he found that there was no hole in it, and there was a long underground passage in the room.into a huge basement.According to Yun Yun, that is the real Dan Room, which has a total of six separate alchemy rooms.

“It appears that these alchemy rooms are underground, mostly for the convenience of the ground.”Qin Yuxuan walked on the side, while fainting.

When he came to the hall of Dan's room, he found that there was only one lean old man sitting in the chair to guard.And what made him cry and laugh was that this thin old man was still dozing.

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

“This old man!I want to come to alchemy, please help me open an alchemy room?"Qin Yuxuan first asked a whisper, and then saw that the old man still did not wake up, so he had to shout.

The dry old man woke up from his sleep at this time, he opened his eyes and glanced at Qin Yuxuan for a moment, and then looked at the clothes of his fellow practitioners who were practicing and wearing, Fang was surprised and said, "I am not mistaken!"Do you also want to come to the alchemy of a disciple on the second level of the Eunice period?It’s not a sudden whim, is it?”

Qin Yuxuan frowned and said, “Senior, there are rules in the Mofi people, are not allowed to use Dan Room by the disciples?”

“Of course there can be no such rules.However, this alchemy depends on talent, and the herb consumed in the learning process is very much, the old man felt that you are afraid that you can not afford the required spiritual stone!"The old man was clearly suspicious.

"Senior, the boy also just wanted to try whether he had the talent for alchemy, so he prepared a few materials to try it, of course, the best, the practice can not come out, even if I can't, I continue to focus on the cultivation of magic!" 」Qin Yuxuan said with a sincere face.

"All right!In any case, the alchemy room has been empty for a long time, and only the guest alchemist will open when he comes to the alchemy.Give it a stone and try it!In addition to the No. 1 alchemy room is reserved for him, you can not enter, the other five alchemy room you can enter casually!"The old man finally tucked away.

Qin Yuxuan nodded, but took five stones out of his pocket and handed it over.

He smiled and said, “Senior, the boy is poorer and there are not many spiritual stones.”In addition to the spiritual stone that rents the alchemy room, the other four are filial piety to your old people.I’ve never used these five alchemy chambers, and I don’t know which one is better.I don’t know if you can point it out?”

The old man also stood still, then opened his eyes and smiled, “Boy, it seems that you are still a human being!”The old man also reminded you that there is still a difference between the alchemy rooms in this Dan room.In addition to the No. 1 Alchemy outside, among the other five alchemy rooms, the ground fire in Room 5 is the most stable, and you can go there to try Alchemy!”

He opened the ban in the alchemy room and handed him a key.

Qin Yuxuan looked at it and saw that the key was engraved with a "five" word, and held it in his hand.He thought that he had spent four more stones or worth it.

So, after thanking the old man who saw the door, he strode to the door of the No. 5 alchemy room, and then opened the door with the key and went in.

...

After entering the room, Qin Yuxuan carefully looked at the situation of the alchemy room, only to see that in the No. 5 alchemy room, there is a small bed made of blue stone, there are covered and pillows, and in front of the small bed, there is a green futon, it seems that for the alchemist's people to sit and rest.

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

Qin Yuxuan tried to rotate the handle, and saw a sharp red flame spewing on the top of the pillar, burning incomparably, and it scared him.

A moment later, Qin Yuxuan calmed down and tried to turn the handle again.

He found that turning to the left is to adjust the fire, and turning to the right is to adjust the fire, which is very convenient.

After mastering this decision, Qin Yuxuan took out the jade yellow pill Dan Fang obtained from Cai Jin, and the "Indignant Heart", and began to carefully study it...

After reading the book of the alchemist's heart, Qin Yuxuan finally had a certain understanding of the alchemy.The main secret to know the refining of the drug is the control of the fire during the alchemy, and at what time to open the furnace to take Dan.

And he previously thought that the more important projects, such as the matching of various herb raw materials, and the proportion of the number of espirits, were clearly stated on the Dan side as early as the Dan side, only need to be matched according to the introduction of the Dan.No need to think about it.

Of course, Alchemy's experience also shows that when configuring the drug raw materials, it is appropriate to increase or decrease the material.It is only necessary to follow the fixed proportion required by the Dan side, so that the number of Danes can be controlled once.

However, the more material, the better for the alchemist, the more difficult it is to control the fire and furnace opening time.It’s easy to say, but it’s hard to do!

According to the "Alchemist Heart" Jade Jane said, just accurately control the furnace fire, grasp the opening time, and measure the best time to go, these three problems do not know how many alchemists.

The success rate of the first alchemy of the general priesthood is almost always less than one percent, and even after special training, the number of monks with a certain alchemy talent will not exceed 10,000 within half a year of starting alchemy.

Of course, after years of practice, after a pile of countless ethereal herbs, an ordinary alchemist still has a one-third success rate and produces low-grade drugs.

However, this is also limited to refining his familiar medicine, replaced by the drug he has not refined, I am afraid the success rate is still very low.

Therefore, whether a drug can be successfully refined out depends on whether the experience of the alchemist is rich.The more alchemists the number of alchemists, the greater the probability of becoming Dan.Therefore, the alchemist and the refiner and the conformist have become the three most expensive professions in the cultivation world.Of course, they are also the three most delicious occupations.

After Qin Yuxuan learned these things from Cai Jin's "Alchemist Heart" booklet, his heart was mostly cold.He secretly thought: he has never refined any medicine rookie, although now there are more than a dozen pieces of jade pills.But at their own level of alchemy, I am afraid that I will not be able to use a single drug.

However, now the spiritual stones that rent the alchemy room are handed over, even if the ducks are on the shelves, Qin Yuxuan also has to try it.

So, after taking a deep breath, he took the purple gold ding from the storage bag and placed it on the top of the hollow pillar...
