"Huh?" The sudden change startled Ding Wenwen, thinking that it was her own mistake that made a big mistake, and looked up at Duan Qing in amazement, expecting to be forgiven.

However, seeing Duan Qing with his eyes closed, he didn't know what he was thinking, probably because of the excitement of the successful refining, he couldn't help himself, right?

I couldn't help but quietly stick out her tongue and gently reached out to get another one, but as soon as her thumb and index finger touched, she suddenly turned into powder silently again, she suddenly realized something, reached out and grabbed it, but only grabbed a handful of powder, as if everything was an illusion!

Ding Wenwen's complexion couldn't help but change greatly, as if she had bumped into a mirage in the depths of the desert, and subconsciously looked at Duan Qing, who was like the backbone.

Duan Qing's brows furrowed, very deep.

Refining pills is the embodiment of the purification and extraction of many ordinary medicinal materials to a certain limit, just like someone who has suffered an internal injury, if he boils medicinal juice, he may have to drink several large bowls every day, and this time may take at least a few months to heal, but the pill is different, one pill goes down, and the medicine is eliminated.

It is completely a process from quantitative change to qualitative change.

And this furnace pill just now, Duan Qing vaguely felt that there seemed to be a link missing. He didn't know what it was, in fact, most of his books were picked up from the garbage mountain, and most of the books that could be discarded were missing pages and chapters, and some were even missing most of them altogether. His knowledge of pills also came from such books, or several incomplete books, pieced together, to form a general concept in his mind.

Relatively speaking, the prescription is much more relaxed, and it is estimated that most of the people in this world, except for the farmers who accept their fate, will know some prescriptions that are at least rudimentary. After all, there are too many things involved in collecting materials, which materials can be matched with what recipes, good recipes are naturally more valuable, and the same is true for refining materials.

Perhaps they know very well that the monks and people living around the garbage mountain have no chance of alchemy or refining, so the three major parties have never shied away from this aspect, and sometimes they will issue prescriptions and issue a reward order to gather the materials.

Therefore, Duan Qing could be sure that there was no problem with the recipe, from the beginning of refining to the present, there was no problem with the Dan furnace, so the problem still appeared in his own degree of control, it was obvious that there was a problem in the link where the material was transformed from liquid medicine into Dan.

It should be a matter of furnace temperature.

Turning his head to look at the materials, there are still three copies, even if the temperature is controlled one high and one low, and two more materials are wasted, there is still one chance left, Duan Qing said to Ding Wenwen without any hesitation: "Ignition." ”

Looking at Duan Qing's expressionless but resolute face, Ding Wenwen was overjoyed, what she was most worried about was that Duan Qing's first failure, the second failure, would have a bad psychological shadow on him, at this time he finally put his mind at ease, and was just about to sacrifice the Samadhi True Fire, but he saw that there was still a lot of powder in the Dan furnace, as long as he put it in the fire, it would be burned clean, and he hurriedly said a word, wait, and began to grab the powder and put it into a small porcelain bottle: "These are purified essences, which are much more effective than those boiled medicinal juices." Then he carefully put it in his purse and licked his fingers.

Duan Qing: "......"

The strange fire was put into it again, and the Dan furnace soon emitted the temperature, and put in a portion of the material, Duan Qing carefully controlled the temperature, very carefully observed the degree to which the material was burned, and drove the true qi, through the transformation of the Dan furnace, the true qi went directly to the inner room, very carefully but quite resolutely removed the waste residue, and gradually, the true qi turned into the shape of a needle, and almost every black spot in the boiling liquid was eliminated.

Ding Wenwen's eyes couldn't help but light up, although this is the ability brought by the Dan Furnace, but you also have to know how to use it, it seems that now you can be completely sure that Duan Qing has not only not been hit, but has become more proficient, and the purity of the medicinal juice has also reached an unprecedented level!

Duan Qing was already ready to waste two materials, so he was even more bold to make various attempts, and even communicate with the Dan Furnace, of course, he didn't get any response, and he couldn't help but laugh at himself, this is just a yellow-level Dan Furnace, it is impossible to exist in the Instrument Spirit, but he has mastered the specific ability of the Dan Furnace to transform True Qi, not to mention turning the True Qi into a needle, even if it is a shovel, it is always a harvest.

Everything went very smoothly, the liquid medicine began to jump, Duan Qing planned to try to warm it up first, the true qi that suppressed the different fire gradually weakened, and at the same time released a part of the water through the drainage hole, the liquid medicine beat even more violently, and it was almost about to jump out, Duan Qing hurriedly sealed the slag discharge port with the true qi, and only heard the sound of "crackling", as if popping popcorn, and even the Dan furnace began to vibrate.

Ding Wenwen was obviously frightened, and looked at Duan Qing with some panic, but Duan Qing had already made up his mind to carry out the high temperature to the end, so he just firmly grasped the Dan furnace with one hand, preventing it from swaying, and at the same time increased the fire.

"Hum!" for a moment, I don't know what's going on, a buzzing sound emanated from the Dan furnace, which seemed to resonate with something, and in an instant, those naughty and almost naughty medicinal liquids instantly stopped, even the medicinal liquids hanging in the middle of the inner room stood still, as if time had frozen, Duan Qing couldn't figure out what was going on, and was a little overwhelmed for a while...

Suddenly, a stream of air erupted from the Dan furnace, and the hair of Duan Qing and Ding Wenwen who had been impacted flew up, and the reactions of the two tempered in the suffering were instantly revealed, and they fell to the ground almost at the same time, their hands were next to the weapons, and their bodies were ready, as fast as if they had been rehearsed countless times.

But after waiting for a while, the expected explosion did not come, but smelled a strong fragrance, and the two couldn't help but get up in surprise, looked at each other, and both understood each other's doubts: "Why is there no medicinal smell, but a fragrance?"

Duan Qing got up and cautiously came to the Dan furnace to observe the feeding port, but was stunned to find that the mouth that had always been open before did not know when it was closed, where did the air flow come from?

Reaching out to open the furnace lid, he couldn't pick it up, there seemed to be something inside that firmly sucked the lid, Duan Qing exerted force in his hand, and the power of the fivefold realm of the Qi refining period suddenly worked, and the furnace lid made a sound of "pop!" vacuum pouring air, and a rich aroma suddenly wafted out.

The room is full of fragrance!

Ding Wenwen's eyes widened and she covered her mouth in disbelief...
