When Yu Fei heard this, he suddenly came to his senses: "Dao Chief, you mean that you know alchemy." ”

"Haha, don't you know, Poor Dao was a world-famous master of Wai Dan back then." Kun Yuanzi said proudly,

"Wai Danjutsu, ah...... Dao Chief, you are actually ......, this ...... It's great. ”

Taoist alchemy, and divided into the outer Dan and the inner Dan, the so-called outer Danshu, is the Taoist through a variety of secret methods to smelt the elixir, used to eat, or directly take some sesame grass, in order to ignite their own yin, so that it into yang, in addition, the Taoist outer Dan can also refer to the "void of the pure spirit of the qi", and the inner Dan is another name for Taoist practice, to practice into immortals and achieve immortality for the ultimate goal, this technique to the human body for the Dan furnace, so called the "inner Dan", different from the "outer Dan" with the use of the Ding for the furnace,

Knowing that Kun Yuanzi was actually a master of the Outer Dan Technique, Yu Fei was a little incoherent with excitement, with him, why worry about not being able to get the Qi Refining Pill,

"Dao Chief, why don't you teach me how to make a Qi Refining Pill." Yu Fei said eagerly,

"Brother Yu wants to learn the Wai Dan technique, but there is no problem in teaching Brother Yu it, it's just that special utensils and materials are needed to make Qi Refining Pill, and I'm afraid I have to prepare for it."

"It's all on me, Daoist, tell me what you need, and I'll do it immediately."

Yu Fei's anxious appearance provoked Tang Yan to purse her lips and laugh on the side: "You, it's necessary to be so anxious, I think you should hurry up and rest for a while." ”

"What the princess said is very true, Brother Yu's face is so pale, he must have moved the qi of True Yuan, it is better to recuperate at home these days, and there is no need to worry about alchemy for the time being."

Tang Yan and Kun Yuanzi said this, Yu Fei was right to think about it, the top priority now is to recover his vitality first.

After a few days of cultivation adjustment, Yu Fei gradually recovered.

Under his repeated requests, Kun Yuanzi made a list of the utensils and materials needed to make the Qi Refining Pill: a three-legged bronze Dan furnace, a few Qi Gathering Spirit Runes, Dansha and some Chinese medicines, those Chinese medicines are nothing special, ginseng, astragalus, atractylodes, yellow essence, licorice, etc., are some of the more common qi-replenishing Chinese medicines.

After Yu Fei looked at the list, he couldn't believe it, could such an ordinary medicinal herb actually make a magical Qi Refining Pill?

Kun Yuanzi told him that this was only the material for the production of the Beginner-Rank Qi Refining Pill, but if he wanted to make the Middle-Rank or High-level Qi Refining Pill, the materials needed would not be so easy to obtain.

Kun Yuanzi helped draw the floor plan of a three-legged bronze Dan furnace, this bronze Dan furnace is divided into two layers, the upper layer is the circular furnace body where the pill is placed, with a furnace lid, between the three feet and the furnace body, there is also a layer of interval, which is the place where the fire charcoal is placed, and on the furnace body and lid of this bronze Dan furnace, some strange runes are clearly visible,

Yu Fei took this floor plan and immediately went to find a handicraft production company, but after waiting for a few days, he sent a bronze Dan furnace that was one foot high and had fine craftsmanship, Kun Yuanzi picked up this bronze Dan furnace and looked at it carefully, and was very satisfied.

When Yu Fei saw this bronze pill furnace, he immediately thought of the Qi Gathering Jade Ding on the top floor, and he opened his mouth to Kun Yuanzi and asked, "Dao Chief, isn't that Qi Gathering Jade Ding also used for alchemy, and what is the difference between it and this bronze Dan furnace?" ”

"Hehe, the Qi Gathering Jade Ding is very different from this bronze Dan furnace, the Qi Gathering Jade Ding is actually also known as the Qi Dan Furnace, in ancient times, Taoism had an extremely advanced alchemy technique, which is to refine the void and clear the spirit of the Qi into the Qi Spirit Pill, and this Qi Dan Furnace is a necessary thing for refining the Qi Spirit Pill."

"What's so special about the Qi Spirit Pill?" Yu Fei asked,

"Qi Ling Dan is also known as the Qi Elixir, containing an extremely powerful aura, it is said that Zhang Tianshi of the Eastern Han Dynasty is taking the Qi Ling Pill that he himself refined, so that he reached the realm of practicing God and returning to the void, and finally became an immortal, but it is a pity that the alchemy of the Qi Ling Pill requires the alchemy of the person to have a very high Taoist cultivation, not ordinary people can refine, and refining this Shen Dan is a matter against the sky, so it will be slowly lost later."

"You don't even know the Taoist." In Yu Fei's heart, Kun Yuanzi is simply a jack-of-all-trades, and there doesn't seem to be anything he doesn't understand.

"If you know how to refine this Qi Spirit Pill, Poor Dao may have already attained Dao and ascended to immortality, and he will not use this evil sect ghost cultivation technique to achieve the goal of immortality, and finally turn himself into such a flying body that is not like a human and a ghost is not like a ghost." Kun Yuanzi has always been obsessed with his flying body,

Yu Fei comforted on the side: "The Taoist chief doesn't have to mind too much, didn't Comrade Xiaoping say: 'No matter whether the cat is black or white, if you catch a mouse, you are a good cat,'"

"Comrade Xiaoping, what a person."

"Oh, yes, I forgot for a while, you don't know him well, he used to be the leader of the country, a bit like the emperor of ancient times." Yu Fei could only explain to him like this,

Kun Yuanzi seemed to understand: "It turned out to be an emperor, and he was disrespectful. ”

"He's been dead for more than ten years, let's stop talking about him, Daoist, let's talk about how to use this bronze Dan furnace." Yu Fei diverted the topic,

Kun Yuanzi said: "With this bronze pill furnace, when the time comes, as long as the materials required for refining the pill are powdered, mixed with the paper ash after the Qi Gathering Spirit Rune is burned, kneaded into the shape of a pill, and then these pills are placed in the Dan furnace to cook for a few hours, if there is no accident, the Qi refining pill can be made within a day." ”

"It's as simple as that." Yu Fei couldn't believe it,

"It's as simple as that, the Beginner Qi Refining Pill is actually very easy to make, as long as you have this alchemy furnace and Qi Gathering Spirit Rune, and with the right materials, you can make it." Kun Yuanzi replied with certainty,

It seems that the process of this alchemy is not as complicated as imagined, it seems to be not much different from cooking, but it takes a little longer.

At this time, Kun Yuanzi spoke again: "By the way, Brother Yu, among the materials for making pills, ginseng is the key, and the last is to use wild ginseng that is more than 100 years old. ”

"What,,100-year-old wild ginseng." Yu Fei was startled when he heard this, where can I get wild ginseng that is more than 100 years old now, even if it is more than ten years old, I am afraid it is already very rare, and even if there is, it must be a ridiculously high price.

He suddenly understood why there were so few people refining pills now, I am afraid it was not because the alchemy technique was lost, but because the materials used in alchemy were too difficult to obtain.

After thinking about it, Yu Fei suddenly thought that among the materials of the black jade intermittent paste made by Ding Laosan, there are no hundred-year-old wild ginseng, Ding Laosan has a wide range of roads, maybe he can still have a century-old wild ginseng there,
