After some explanation, Zichen knew that this Pei Yuan Dan had a large number of demand bases, and it was even a kind of pill that could be used as a "currency", and many big forces used Pei Yuan Dan to replace money when making transactions, which not only saved a lot of trouble, but also kept it in his hands and kept without it.

Compared with the name of Pei Yuan Dan, Pei Yuan Dan is only a first-class pill, and the medicinal materials needed are extremely simple, that is, three cheap popular medicinal materials, namely black root grass, double flower, and earth robe fruit.

Pei Yuan Dan can even be tried by a beginner pharmacist apprentice, but its biggest problem is the extremely low "Cheng Dan rate".

To put it simply, even a pharmacist of the fourth and fifth levels of the Great Qian, when refining Pei Yuan Dan, he should have half of the Cheng Dan rate!

Because of this, although the medicinal materials for refining Pei Yuan Dan are extremely cheap, and the threshold for refining is also extremely low, the price of Pei Yuan Dan is not very cheap, and if there is no family or power support behind him, Pei Yuan Dan can be described as a luxury for individuals.

As for the high-quality Pei Yuan Dan, it is basically difficult to buy it in the pill shop, because the high-quality Pei Yuan Dan is more effective, and it is often hoarded by various forces for the cultivation of genius disciples in the forces.

Knowing what was going on, Zichen smiled bitterly and said, "I see...... If it really doesn't work, I can only buy low-quality Pei Yuan Dan for the time being......"

Nie Xiaohuan blinked his eyes and laughed: "Brother Zichen, these pills you need, I can actually help you refine them." ”

Zichen was stunned, but noticed that Nie Xiaohuan's expression didn't want to laugh.

Sticking out his tongue and making a grimace, Nie Xiaohuan also became serious and said, "Brother Zichen, although my medicinal Dao skills have not been certified, they are not inferior to second-level pharmacists, and refining Pei Yuan Dan is not a big problem." ”

Zichen was taken aback and looked at Nie Xiaohuan in disbelief.

You must know that in the entire Iron Sword Gate, there are only a few first-level pharmacists, and all of them are old men, who look up to the sky when they walk, and never look at people!

However, after getting along with each other for these days, Zichen has some understanding of Nie Xiaohuan's character, and Nie Xiaohuan is not the kind of person who can lie.

Since Nie Xiaohuan said so, Zichen had nothing to hesitate, and after making preparations with Nie Xiaohuan and getting the materials needed, Nie Xiaohuan took Zichen to the second floor of the medicine hall.

As soon as I walked up the stairs and walked into the room on the second floor of the medicine hall, a trace of heat hit my face. Zichen knew that this should be the alchemy room, and followed Nie Xiaohuan's footsteps and walked in.

In the center of the alchemy room is a quaint and old medicine pod. In addition to the medicine pod, a medicine table was placed on the left side of the medicine pod, which was used to place alchemy materials and tools such as medicinal herbs, and on the right was a swarthy bucket of charcoal, which always had a strong smell of charcoal fire in this pill room.

Nie Xiaohuan briefly introduced Zichen.

When the pharmacist refines the elixir, he can't do without the flame. And the flame used in alchemy is also very particular. Generally speaking, the flames of alchemy are divided into three classes, which are human fire, earth fire, and heavenly fire.

When a qualified pharmacist is refining the elixir, earth fire is the most basic condition. Therefore, when the medicine path forces establish a sect, they often choose to build on a geocentric fire vein. For example, the "Medicine King Valley", the leader of the medicine path of Daqian, was built on a living fire vein that did not know tens of thousands of years.

And some capable medicine dao masters, when refining some extremely important pills, even have to use "Heavenly Fire".

Of course, if the conditions are limited and the requirements of earth fire cannot be met, human fire can barely be used.

The so-called human fire is, simply put, the flame made by man. This charcoal fire belongs to the category of human fire, but it is one of the most inferior flames in human fire, in the alchemy, the charcoal ash and other impurities produced by the charcoal fire are very easy to contaminate the pill, affecting the rate of the pill and the quality of the pill.

Because of this, not to mention the medicine master, the slightly more picky pharmacist is scornful of the first-class charcoal fire.

However, after all, the two Nie Xiaohuan sisters are financially difficult, so naturally there can't be any good conditions, and Nie Xiaohuan has always used this charcoal fire to alchemy.

"Brother Zichen, don't worry, although the flame of alchemy is important, the most important thing is the skill of the pharmacist, and a little more refinement is enough to make up for the lack of flame. ”

Nie Xiaohuan smiled confidently, reassuring Zichen. Zichen didn't know much about the way of medicine, and he trusted Nie Xiaohuan more, and after smiling, he nodded.

Nie Xiaohuan quickly put the prepared medicinal materials on the medicine table, then opened the lid of the medicine pod, filled the charcoal in the wooden barrel to the bottom of the medicine pod, and began to warm the pod to prepare for refining the pill.

About a stick of incense, the pod was already warm and the preheating was complete.

Nie Xiaohuan took a slight breath, stretched out his right palm and slapped it on the medicine tripod, and suddenly the "swallowing" cover on the side of the medicine tripod popped open, and a scorching heat came to his face.

"Brother Zichen, when refining the pill, the top cover of the medicine tripod cannot be opened under normal circumstances, and the medicine can only be entered through this swallow. ”

Nie Xiaohuan didn't forget to give Zichen a brief introduction, and as he spoke, he grabbed the medicinal materials from the medicine table with a wave of his right hand, and sent them directly into the medicine tripod from his mouth.

As soon as the medicinal materials fell into the medicine tripod, Nie Xiaohuan immediately slapped his right palm on the side of the medicine tripod, and the slender five fingers and palm pressed rhythmically in several rows of fine holes.

"Brother Zichen, these rows of fine holes are called fire holes, which are used for fire control, with a total of nine rows, and each row has seven fire holes. Through the palm of the hand and the five fingers, these fire holes are pressed regularly and rhythmically, this manual action is called "kneading the fire", and the temperature and size of the flame in the medicine pod can be precisely controlled. ”

Nie Xiaohuan made another introduction.

Zichen nodded repeatedly. Although he didn't know much about the way of medicine, he also knew that for the refining of the pill, the heat in the medicine tripod was extremely important, and the size of the flame, the temperature and so on, even a small difference could cause the failure of the alchemy, or even cause a major accident.

Zichen was still puzzled, and asked suspiciously: "Xiaohuan, this medicine tripod is highly closed, and when refining the pill, the internal situation cannot be seen through the human eye. How did you get an accurate grasp of what's going on inside the pod?"

Nie Xiaohuan smiled proudly: "The fire hole can not only be used to control the flames, but the pharmacist can also grasp the situation inside the medicine pod by sensing the slightly hot air flow flowing in the fire hole." Of course, this is a test of a pharmacist's true strength. ”

Nie Xiaohuan said, his right palm skillfully pressed the fire hole, the movement was clean and powerful, and at a glance, it gave people a sense of stability and confidence.

And Zichen couldn't help but smack his tongue. Don't look at Nie Xiaohuan's easy words, but Zichen knows the difficulty, without using his eyes, he must carefully grasp the situation inside the medicine tripod, and at the same time control the flames through the extremely superb "kneading fire" technique.

All this, without years of hard labor, is simply delusional!

For a while, Zichen was amazed, only to feel that this medicine path was so complicated and profound, and it was not under the Dharma Dao at all!
