Danxin Hall's Hall Master Chen has been in a good mood recently, and a disciple he has always been optimistic about is said to have successfully advanced to the formation cultivation stage more than a month ago.

I didn't expect this disciple to advance so smoothly, you must know that it was only more than three months after he talked to him and asked about things, and this kind of speed was basically something that the most qualified kind of person could do.

This disciple had made an appointment with himself that after the advancement was completed, he would go to the Danxin Hall to learn alchemy, and the days were almost over. As long as this disciple can be entrapped, the work of the Danxin Hall will be carried out in the future, and he can throw all the alchemy work that is not very important to him and concentrate on the research of the most valuable pills.

"Hall Master, there is an Uncle Sun who wants to see you. A new disciple said.

"Got it, let him come here. Hall Master Chen commanded with a smile. It's really Cao Cao, Cao Cao has arrived, this person who has just become his junior brother has arrived.

But looking at the new disciple who left the room, Hall Master Chen couldn't help but sigh, the personnel mobility of the entire Baohuai Hall was very large, and those who stayed were all useless to eat, and there were not many new people who could be of great use, which was why he was so concerned about that Senior Brother Sun.

"Hall Master Chen, I've come to you to learn alchemy. While Hall Master Chen was pondering, Senior Brother Sun had already arrived in the room, and it was Sun Xiaotian.

"Senior Brother Sun, congratulations on your advanced cultivation period, I didn't expect that Senior Brother was so talented that he could complete a breakthrough in such a short time. In this way, we have a lot of time to prepare before the demon slaying meeting. Hall Master Chen praised Xiao Tian greatly.

"The hall master has a good reputation, and I just succeeded by luck, but thanks to the hall master who pointed out the key points of my advancement, I have to thank the hall master well. Speaking of the Demon Slaying Society, this is indeed one of my purposes, but I plan to stay here for a year first, and then leave for a while when the sect assembly is held in a year to do some business. Xiaotian roughly talked about his own arrangements.

"Well, the trade fair after every conference is indeed a good opportunity to do business. But it's not too late to talk about what will happen in a year's time, since the junior brother has arrived, why don't we start quickly. When Hall Master Chen heard Xiao Tian's plan, he immediately decided to start guiding immediately, anyway, his original plan was to train Xiao Tian into the talent he needed within a year.

"Don't worry, hall master, I'm still the same as before in Danxin Hall this time, I eat and live here, and I have plenty of time. Now that I want to learn some advanced pill refining, I feel that it is time to prepare my own Dan furnace, and I want to ask the hall master about the selection of Dan furnaces. Xiao Tian said slowly, he still felt that it was more efficient to do things after everything was ready.

"Oh, Dan furnace, I still have a few here that I don't use often, so I'll give you one. Hall Master Chen said as he took out the Dan Furnace from the bag.

"Hey~ Hall Master, wait, I've been taken care of by you a lot, and I can't take your things anymore. I went to Yinxian Temple this time, and by the way, I participated in the trade fair in Linwu City, and got a lot of production drawings of Dan furnaces. I myself am quite good at refining weapons, so I plan to make a Dan furnace myself. I would like to ask the hall master to tell me about the advantages and disadvantages of this different style of Dan furnace, so that I can choose a suitable one among them. Xiao Tian waved his hand again and again to stop Hall Master Chen, and took out a few drawings and put them on the table beside him.

"Do you want to make it yourself?" Hall Master Chen's voice was a little dissatisfied, wouldn't that mean that he was going to the Hundred Refining Hall next door again?" In terms of the choice of Dan furnace, there are indeed a lot of things to pay attention to, listen to me and you in detail. Hall Master Chen motioned for Xiao Tian to sit down and listen to him speak slowly.

"The Dan furnace for refining ordinary pills, the junior brother has used it many times, that kind of Dan furnace is simple to use and has a large capacity, but it is not suitable for refining precious medicinal materials. The more precious the pill, the more complicated the operation required, often to rotate the entire Dan furnace, and it is not suitable to fill too many raw materials at one time, and a smaller Dan furnace is more suitable. The smaller the Dan furnace, the faster it heats up, and the more difficult it is to control the temperature, so there will be some problems with the Dan furnace that is too small. In terms of the size of the Dan furnace, it still depends on my own habits, I am already quite proficient in temperature control, and I usually use some very small Dan furnaces, or even the kind that can only refine one pill at a time. Master Chen first introduced the choice of size.

For Xiao Tian, a small Dan furnace should be more suitable, so that it can cope with all kinds of situations, anyway, he is not yet at the stage of refining the highest grade pill, and it would be better to produce more.

"When it comes to manufacturing materials, the more advanced the better. However, it should be noted that different materials will affect the five elements of the Dan furnace, and the Dan furnace with different attributes will have a great impact on the refining of the elixir. If you happen to refine the elixir of the mutuality attribute, then you can get twice the result with half the effort and it will be easier to succeed, but if the elixir you refine is compatible with the attribute of the Dan furnace, then it is basically difficult to refine. If you plan to use only one Dan furnace all the time, then it is better to choose some non-attribute materials, although there will be no bonuses, but there will be no pills that cannot be refined. Hall Master Chen also introduced the choice of the five elements of the Dan furnace.

This aspect is too complicated, Xiaotian doesn't have time to build so many Dan furnaces now, so he naturally has to choose a Dan furnace without attributes.

"In terms of structure, it's more complicated, but the junior brother should just want a more versatile Dan furnace now, then several kinds of inner furnaces here are more suitable, more Dan furnaces with complex structures, and the junior brother can study it himself in the future." That's basically all there is to say, the impact on other aspects is not particularly big, and the junior brother can decide for himself. "Hall Master Chen only briefly talked about the structure, obviously wanting Xiao Tian to choose a simple structure, so that the time for refining the Dan furnace is relatively short.

"Thank you hall master for teaching, I already have some ideas, so I will go to make the Dan furnace immediately, and when I come back, I will ask the hall master to teach me the way of alchemy. Xiao Tian chose the Dan furnace and immediately said goodbye and went to the Hundred Refining Hall next door.

In the Hundred Refining Hall, Xiao Tian also met the Ning Hall Master, and he already knew about Xiao Tian's advancement, and the two of them were polite again. Knowing that Xiao Tian was going to learn alchemy, he was a little disappointed, and said something to persuade Xiao Tian to concentrate on refining.

In fact, Xiao Tian has found over the years that among the skills he can now, the fastest way to make money is refining weapons, so why doesn't he want to concentrate on refining weapons? Unfortunately, in order to stay in Yan Dan now, he has to learn alchemy first no matter what, so he had to reluctantly refuse the invitation of the Ning Hall Master, only saying that he would come to refine weapons again in the future.
