Refining a superficial elixir requires hundreds of medicinal materials, and there is no shortage of precious things, counting hundreds of taels of silver, if you refine a high-grade elixir, wouldn't it be hundreds or thousands of medicinal materials.

It turns out that this alchemy also has to be smashed with a lot of silver, otherwise it will be all up to you to collect medicine by yourself, and you don't know that it will be the year of the monkey.

Fang Ling thought to himself, so he went to the Tai Hospital, fortunately, the medicinal materials in the palace are everything, and the medicinal materials worth five hundred years can be done by giving Lin Mowen two hundred taels, if this elixir is really effective, then it is worth spending more silver.

Back to Binghua Palace, the two came to the kitchen and put the medicine tripod on the stove, fortunately, this tripod is not big, it is just right to put it in, and then stuff some firewood below, and there is a lot of firewood in Binghua Palace, most of which Dong Canghai got from the imperial dining room.

Next, Xiao Xue began to guide Fang Ling to classify the medicinal materials, the grinding of the powder, the chopping of the chopped, the washing of the washing, the hundred or so medicinal materials are almost divided into ten categories, each of which has a different treatment method.

It took half an hour just to clean these up, but Fang Ling didn't feel upset at all, on the contrary, he took a very careful note of the treatment of these medicinal materials, so that in the future, he could freely refine this Pei Yuan Dan, if the effect was very good, then his mother's body would be able to be healthy, and he would also be able to strengthen his body and become stronger, and he would have a good chance of winning if he encountered any immortal sect disciple fierce beast or the like in the future.

After everything was ready, Xiao Xue explained seriously: "In addition to medicinal materials, this alchemy technique is fire. There is a difference between a gentle fire and a martial fire, as well as a difference between an inner fire and an outer fire. ”

"Inner fire and outer fire?" Fang Ling wondered.

Xiao Xue bowed slightly: "The alchemy of cultivators is different from the pills refined by ordinary doctors, emphasizing the word qi, you should already know how to absorb the qi of heaven and earth through the cultivation technique hidden in the dagger, this kind of qi of heaven and earth inhaled into the body is called internal fire, and what is born from the firewood under the ding is the outer fire." In the process of alchemy, you not only need the help of the external fire, but also need your own internal fire alchemy. Of course, it is only when you reach the realm of Xingqi that you can get a first glimpse. I don't have my natal true blood now, and I can't use my true yuan to detect the situation in Dingzhong, so I can only use external fire to make the most superficial elixir now. During the whole process, you must concentrate and not be distracted in the slightest, otherwise you may make the alchemy work fall short. ”

Hearing the word True Yuan, Fang Ling was secretly taken aback, and couldn't help but glance at Xiao Xue, listening to her talk about the realm of martial artists, you have to go to the Huayuan realm to refine the true yuan, and it takes seventy or eighty years for ordinary people to practice to that level, even if it takes forty years for a disciple of the Immortal Sect, this woman is only in her early 20s, and she can actually practice the true yuan?

He was surprised in his heart, but he didn't show it on the surface, but began to make a fire, according to Xiao Xue, this Pei Yuan Dan must be boiled with a martial fire, and the medicinal herbs must be melted before it is slowly boiled on low heat, and finally form a pill.

After the fire started, the medicine pod began to heat up slowly.

Fang Ling first poured a bowl of hundred-year-old dansha into it, the color of this dansha was vermilion, because it had been stored for a hundred years, the red color was even more dim, but after pouring it in, the color immediately became bright at the temperature, like human blood, and after the dansha was boiled to a certain extent, Fang Ling began to stir while pouring various medicines into it.
