The shopkeeper still used real fire to heat the Danding first, and then put the crystals condensed by the condensed active ingredients of a refined herb into the Danding, and then, more or later, quickly or slowly put several other crystals into the Danding.

The shopkeeper explains, "The next step is the fusion of the herbs, where several herb crystals are melted into a liquid state so that they can be fused. In the process of refining herbs, you have to master the refractory degree of each herb, and the crystals with high refractory surnames should first be put into Danding to heat, and strive to melt all the crystals at the same time. ”

Sure enough, several crystals in the Danding gradually softened and melted, melting into a liquid state almost simultaneously. Then, the liquid in the dan ding floated to the center of the dan ding and continued to stir violently.

The shopkeeper said: "After the liquid juice is melted, it is necessary to stir and mix it with divine consciousness, and several medicinal liquids must be completely and evenly mixed, otherwise, the quality of the elixir will drop greatly, and even become a waste pill." Wrapping the liquid medicine in the center of the Danding with divine consciousness and mixing it can prevent the temperature from being too high to destroy the active ingredients of the herb, and also avoid uneven stirring due to premature condensation of the liquid medicine. ”

The liquid in the center of the pill gradually became uniform from several different colors, and then the liquid began to slowly rotate and rise.

The shopkeeper said: "The next step is the process of becoming a pill, first of all, we must maintain the uniform rotation of the liquid medicine, only in this way, the centrifugal force of the liquid medicine will keep the liquid medicine uniform and round." The consciousness should maintain a certain pressure on the liquid medicine, and the speed of rotation should be moderate. The rising speed of the liquid medicine should be uniform and slow, and as the liquid medicine rises, the temperature gradually decreases, and the liquid medicine can be condensed into Dan. ”

Long Xiaoyao listened to the explanation while paying attention to the shopkeeper's cooking. He didn't know if the shopkeeper was deliberately hiding his secrets, or if he was not very proficient in the skills of the Cheng Dan process, but just acted mechanically according to experience.

However, it doesn't matter, Long Xiaoyao is just to watch the entire process of alchemy, and the principles and know-how of Cheng Dan are described in detail in Gu Xiu's alchemy experience.

First of all, the reason why the pill is round is mainly because it is the most stable form. Low-level pills are not enough, high-grade pills, because they contain majestic spiritual power, spiritual power will impact the pill and escape, and the round is the best form to resist the impact of spiritual power, if the pill has water chestnut, the spiritual power will inevitably cause leakage by impacting the weak point of the water chestnut, and the pill will become a waste pill.

The rotation of the liquid medicine is to maintain the roundness of the elixir, but the speed of rotation and the pressure of the divine consciousness to wrap the liquid medicine need to be adjusted according to the degree of the transformation of the liquid medicine from liquid to solid, as well as the strength of the spiritual power of the liquid medicine, and with the condensation of the liquid medicine, the pressure of the divine consciousness must gradually weaken, otherwise, the pill will crack due to excessive pressure, causing the spiritual power of the elixir to leak out.

Of course, in order to do this, it is necessary to have a wood spirit root, so that you can have the ability to induce medicinal herbs, including the refining process of medicinal herbs, according to the alchemy experience of ancient cultivation, you should have a good ability to induce medicinal herbs, so as to ensure that the heating degree of medicinal herbs is moderate, and only then can you ensure that the herbs are evenly integrated.

Actually, it's not that the shopkeeper is hiding his secrets, because the alchemists in the immortal cultivation world now only require the cultivation of the fire surname exercises, which can mobilize the true fire, and there are no special requirements for the wood surname spiritual root, and the shopkeeper does not have a wood spirit root, so he doesn't know these alchemy skills, let alone adjust the alchemy techniques according to his feelings about the herbs.

It is also because it cannot be adjusted according to the actual situation, the shopkeeper only repeats the process of alchemy according to the experience of the machine, and the divine sense is only due to exercise, which is slightly stronger than that of ordinary monks, and the fine control is also slightly stronger, but in fact, it is not up to the level of an alchemist, therefore, this shopkeeper can only refine low-grade pills, and the level of pills is still very unstable, and it is not very high.

And only by sensing the subtle changes of the herbs and adjusting the alchemy technique according to the actual needs at any time can we reach the realm of an alchemy master, and only by doing so can we refine a high-grade pill with abundant spiritual energy.

However, practice makes perfect, the shopkeeper was refining a low-grade elixir aura pill, and the spiritual power of the elixir itself was not strong, so the difficulty of refining it was not too great. And this pill is the main pill that the shopkeeper usually sells, he has refined thousands of pills, but it can also reach a success rate of more than ninety percent, this time, he refined a medium-grade aura pill, with a smug smile on his face.

Long Xiaoyao looked at the shopkeeper's expression and the successful refining of the medium-grade Spiritual Qi Pill, knowing that the shopkeeper did not hide his smuggling in the refining process, but the purification of the herbs was slightly worse when refining. In the process of becoming a pill, the weakening of the pressure of the divine consciousness and the degree of condensation of the liquid medicine did not fully match, and the internal part of the pill caused very slight cracks due to excessive pressure during the condensation process, so that the quality of the pill only barely reached the middle grade.

This is still because the spiritual power of the Spiritual Qi Pill is low, otherwise, the subtle cracks inside the pill will inevitably cause the explosion of the pill and turn it into a waste pill.

Long Xiaoyao meditated on the process of the shopkeeper's alchemy, and based on the alchemy experience he read, he summarized the gains and losses of the shopkeeper's alchemy process one by one, and only after a while asked the shopkeeper a few questions that he still had some problems that he could not fully understand in the alchemy process.

As a result, the shopkeeper's alchemy was only a skilled worker, and he knew almost nothing about the theory and skills of alchemy, or he answered one or two ambiguously, or he simply didn't know anything, which made Long Xiaoyao feel ridiculous about this master.

However, since he already has a general understanding of the process of alchemy and the specific alchemy skills, Long Xiaoyao can slowly explore it with the record of his future practice and alchemy experience, which is actually expected, otherwise, the shopkeeper will not be able to refine some low-grade pills.

Later, Long Xiaoyao asked the shopkeeper to refine two different pills, and as a result, although the shopkeeper successfully refined them, one was a medium-grade pill, and the other was just a low-grade pill, looking at the shopkeeper still putting on a smug look, which made him a little speechless.

Long Xiaoyao now had completely mastered the process of alchemy, and there was nothing to learn from the shopkeeper, so he handed over the negotiated price to the shopkeeper, and seeing the shopkeeper's irrepressible ecstasy, he immediately took his leave and left. However, he bought a large number of ordinary herbs for refining low-grade pills in the alchemy shop before leaving the market.

Long Xiaoyao stayed in a mundane inn at the foot of Mount Hua and began to try to refine medicinal herbs. Since the herbs he refined were all low-grade herbs, the difficulty was not very great, and he had practiced the fine control of his divine sense for several years according to the alchemy experience of ancient cultivation, and it was not difficult to refine the essence of medicinal herbs with his divine sense, he was only slightly inferior in the temperature control of the true fire, either burning the herbs, or melting for too long.
