Although Xiao Tian worked hard to learn the knowledge of alchemy, the interference factors were too great, uh, it was too much, after three months, the demon subduing meeting was over, and Hall Master Chen and the others began to be busy refining the most precious pill, and Xiao Tiancai finally got the opportunity to start alchemy.

This alchemy room is somewhat similar to the stone room for refining materials, the outer gate is a multicolored stone door, and the twelve dragon heads inside are distributed on the wall and the ground, but there is no big ding, and there is a huge Dan furnace in the center.

The Dan furnace has the same color as the alchemy table, yellow and green, as if it was made of some kind of metal. Some alchemy rooms do not have a Dan furnace, so you need to bring your own Dan furnace.

Why is the sect so stingy, and people still need to bring their own Dan furnace for alchemy?

After thinking about it for a while, Xiao Tian understood that compared with the unified style of Dan furnace, the Dan furnace carefully selected by himself must be of higher quality and can improve the success rate of alchemy. It seems that this alchemy is much more difficult than refining, and there is no need to prepare the tools by yourself for refining, and the success rate is also very good.

It seems that he will have to have his own Dan furnace in the future, and maybe a set of refining equipment is also good. But these things are so big, to fit into the bag like this? Do you have to pay a high price to buy some high-end items that can hold large items, are the monks who play alchemy so rich?

This is Xiao Tian doesn't know, the large Dan furnace in front of him now is specialized in refining some cheap ordinary pills, and the Dan furnace can be refined more at one time. However, it is difficult to succeed in the large furnace of high-grade Dan medicine, and it is necessary to use a small furnace to carefully refine it little by little, so most of the private Dan furnaces use small Dan furnaces, and some are only as big as a casserole.

After thinking for a while, Xiao Tian took out the materials and prepared to start the first alchemy. What he wants to refine today is the easiest Bigu Dan, although this is also the cheapest, and there is no profit, but this Bigu Dan is still very useful to Xiao Tian now.

Each task only needs to hand in the specified amount, and the other pills can be left by themselves, Dan Xintang and Chen Hall Master do this, and if you don't do this, it will cause others to be disgusted. Unlike refining weapons, there are only one or two pieces at a time, alchemy can produce a lot more pills at a time, and the significance of pills to cultivation is needless to say, it can be sold for money to exchange for spirit stones.

Xiao Tian sat down on the futon in the corner of the wall and took out a few large bottles, which were all raw material powder of Bigu Dan, Bigu Dan was cheap, and now everyone had no time to refine this low-priced product, so Xiao Tian easily received a lot of raw materials back. That's not all, he's got a lot more in his bag.

Bigu Dan can produce more than a dozen in one furnace, and it is said that twenty or thirty in one furnace with good alchemy technology is no problem, and the materials that Xiao Tian received this time are enough to refine seven or eight hundred, and it is not a problem to divide it into fifty refining. This Bigu Dan can be refined in more than half a day, although it takes more than a month to practice these things, but since the Bigu Dan is refined, there is naturally no need to go out to eat.

As for sleeping, Xiaotian can't even sleep in Bigu. However, Xiao Tian can sleep as long as he wants, and he can rest while refining the pill.

This is also thanks to the fact that the refining of Bigu Dan is not very complicated, it is basically waiting for high temperature heating, and there is no need to operate for a long time in the middle, as long as you don't play with it, you can sleep, cultivate or something, but those high-grade pills will not work.

But don't get away with it.

Everything else is secondary, and alchemy here is the goal, otherwise why would you still be stuck in this stone room and go outside to cultivate?

After thinking about it for a while, Xiao Tian adjusted his state, and then rushed to the Dan furnace to make a decision and opened the Dan furnace. Xiao Tian let the bottles in front of him float over, poured more than a dozen pills of raw materials into the Dan furnace, and let the bottles fly back.

At the beginning, it is good to start with the minimum amount, if the raw materials are valuable, Xiaotian can't wait to refine them one by one.

Xiao Tian was already too familiar with the operation of the dragon head, he easily manipulated the dragon head to spew out flames, and after less than half an hour, the Dan furnace was already hot, exuding an astonishing high temperature, and a trace of heat came out of the top of the furnace.

As time passed, the Dan furnace emitted a trace of medicinal fragrance, Xiao Tian unhurriedly increased the firepower, and fought against the Dan furnace, causing the inner furnace inside to start spinning. Now that the medicinal powder in the Dan furnace has begun to coagulate, it can be heated for a while, and it can be catalyzed with the highest temperature to carry out instantaneous condensation.

After a while, Xiao Tian estimated that the time was almost up, so he controlled all the dragon heads and sprayed at the Dan Furnace with maximum firepower, and the Dan Furnace was completely enveloped in blue flames, but the medicinal fragrance emitted was getting stronger and stronger.

Only after a while, Xiao Tian stopped the fire, and counted silently for a while before turning on the Dan furnace.

The success of the pill mainly depends on the mixing ratio of the raw materials, the control of the heat during alchemy, and the grasp of the time to open the furnace to take the pill.

The first two items are not a big problem for Xiao Tian, the number of raw materials and quantities are clearly stated in the formula, Xiao Tian is confident that he will never make a mistake in the proportion after several months of practice.

In terms of fire control, the problem is not big, Xiao Tian, who has rich experience in refining, does not say that the control of the mixed yuan mountain fire is superb, and he is also perfect. After studying the classics and asking Chen Tang Master for advice, he thought that there would be no problem with this Bigu Dan.

But in the end, Xiao Tian was not sure of this step of taking Dan.

Even a few people in the sect who can be called alchemy masters have to admit that even if they take action in person, the probability of being able to become a pill is not too high, only about half, and this is still the best pill for refining them. Therefore, let alone a novice like Xiaotian, nine times out of ten it will not work.

Xiao Tian's first alchemy failed.

The elixir he took out was not fully formed, it just turned into a small ball instead of a compact elixir. There is even mud around it that has been made of scattered raw materials, which should not have been present if the ratio of raw materials is not wrong.

It seems that it was a little early to take the Dan, although it was taken according to Bishop Chentang's strict silent time, but it still failed. It must be that the number of furnaces that Master Chen usually refines is large, and the heating time is long when it is condensed into a pill, and the furnace is opened earlier.

This is troublesome, he didn't know that when Master Chen was refining the Bigu Dan, he couldn't refine a few pills at a time, and the time he said was naturally not accurate, and now he was very busy, and he wouldn't have time to teach Xiaotian again, he had already said that Xiaotian could only explore by himself during this time.

It seems that I can only try it again and again, and I will know the rules when I accumulate more experience, but fortunately, this Bigu Dan is not very difficult, and there are enough materials.
