The main ingredient of Na Yuan Dan is a three-hundred-year-old medicinal material that has greatly replenished vitality, and there is no specific prescribed type, as long as it is a medicinal material that contains abundant vitality. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 It is not difficult to adjust the auxiliary dispensing according to the type and year of the main medicinal materials, and it is not difficult for Lu Fei to make this kind of compatibility in medicinal properties.

On the Nayuan Dandan prescription given by Qianhua Zhenren, there are three groups of medicinal materials, and the main medicinal materials are Lingshen, Astragalus, and Zhongling Grass that are more than 300 years old. These kinds of medicinal materials are common elixirs, but the demand for the year is three hundred years, unless it is cultivated by the sect, it is extremely difficult to see such a high year of elixir in the wild. And even if there were, it was in those places where people were off the beaten track and in danger.

Lu Fei chose the most simple and easy to use, and it was also the one with the strongest medicinal effect of these three groups of pills.

After taking all the medicinal materials needed to refine the elixir, the next step was to start testing this elixir. The old rule is to use the Mu Feng incarnation in the Wood Spirit Domain to preliminarily refine it in order to master the refining experience of this elixir.

The flame is still the core rune fire in the Wood Spirit Domain, and the flame of rebirth still needs to be refined for a few days, and even if the refining is completed, it will take a while to master. In addition, there was also a spiritual flame the size of a sesame seed in the Wood Spirit Domain, which was another reason why Lu Fei quickly left the sect's treasury, he stole the spiritual consciousness source of the Geocentric Sparrow.

When he was in the warehouse, Lu Fei originally thought that he would miss this Lingyan, but he didn't expect a message from the Earth Dragon to directly tell Lu Fei what the so-called Heaven and Earth Alien Fire was in essence. Lu Fei learned of this news, and naturally smoothly used his advantage as a spiritualist to communicate with the origin spiritual consciousness of the geocentric finches. After making some promises, the Earth's Heart Sparrow obediently escaped his core origin through that layer of prohibition and entered the Wood Spirit Domain.

And Lu Fei is also very generous, using a lot of spiritual power in the Wood Spirit Domain, and even losing some of the vitality of the Mansion Spirit Fire to help the Earth's Heart Sparrow Flame recover.

In addition, there are spiritual veins like the Earth Dragon in the Wood Spirit Domain, and the five elements of the Wood Spirit Domain belong to the wood and naturally generate fire, so the life of the Earth Heart Bird Flame in the Wood Spirit Domain is quite comfortable now.

According to Lu Fei's estimates, Geocentric Sparrow was able to recover to its heyday after more than half a year, and it was even better than the original. This is a rare opportunity!

The geocentric finch in the treasury of the sect has become a complete empty shell, and the core of the geocentric finch that has lost its core can still support it for a hundred days at most, and it will dissipate. As for which unlucky bastard has to go, or if it is dissipated under the layers of prohibitions in the sect's treasury, it is not within Lu Fei's consideration.

The refining process of Na Yuan Dan was even simpler than Lu Fei had expected, and Lu Fei was now an alchemist with extremely extraordinary skills. The understanding of the Danfang is much stronger than the original, and the reason why the second-order pill is more difficult to refine than the first-order pill is mainly because the material of the alchemy is high in age, strong medicinal properties, many types, and large quantities. For example, smelting the main material, a high-grade elixir, the medicinal properties are self-contained, and it is very domineering, and it is very difficult to peel off the cocoon and remove the useless parts in this basically fixed medicinal property, and retain the useful essence.

The difficulty of refining second-order pills is several times that of first-order pills, and the key reason is that these things test the basic skills of the pill master. Normally, the second-order pill will only be refined when promoted to the foundation building stage, and the third-order pill will be refined only when promoted to the knot pill stage. This is due to the fact that the improvement of cultivation can improve the alchemist's own control, and it will help the success of the smelting of various materials. It's just that many times things are unreasonable, and at present, the cultivation of the Great Xia True Realm is the highest alchemist, that is, where to find a third-order Dan master in the foundation building period.

The first time he refined Na Yuan Dan, Lu Fei was successful, this is a kind of Dan recipe that has been tempered for thousands of years, so the rate of becoming a Dan is not low. Lu Fei's Wood Phoenix incarnation is already a second-order, which is equivalent to the foundation building period, so there is no difficulty, not to mention the bonus of the Wood Spirit Domain.

The refined elixir is like a bird's egg, and the medicinal essence of the elixir gathers into a graceful and colorful silk thread, outlining a dense Dan pattern. This is a top-grade Nayuan Pill, which can be regarded as a good elixir that everyone is vying for among the foundation building monks, and this pill refined by Lu Fei can increase the meditation and penance of the immortal cultivators in the early stage of foundation building for a whole month.

The Na Yuan Dan that usually appears is of inferior quality, and if you take it, you can also increase the pill of meditation and penance for five to seven days, and it will be a frenzy to think about it. After the summary of Mu Feng's incarnation refining the elixir, Lu Fei began to try to refine this elixir with a human body.

Lu Fei is only a cultivator in the late stage of the Qi refining period now, and such an innate condition seriously restricts Lu Fei's hands-on ability at this time.

Several failures in a row were caused by the fact that the True Yuan spiritual power in Lu Fei's body was not enough to use, and smelting second-order medicinal materials was still a little reluctant for Lu Fei. What is said here is that without the help of Mu Feng's cheat device to secretly transform the true element, since Lu Fei has refined this elixir, he will take it out and make a name for himself in the cultivation world. When there were outsiders, it was natural to hide Mu Feng tightly, and after stumbling, Lu Fei finally succeeded in refining Na Yuan Dan.
