Originally, Yang Tianwen could go out to get it by himself, but this person was not familiar with the place, and he didn't care about spending that money for convenience.

Back in the room, Yang Tianwen first laid out a simple soundproof formation, and then took out a few of his own talisman flying knives, and then took out a few high-grade spirit stones, in order to refine the heart of the fire, integrate it into the flying knife, and ban the inferior parts of it, but it can only improve the quality of a few flying knives, and the power is not much improved, but it is still improved.

According to the previous quality calculation, Yang Tianwen's flying knife only has the quality of about sixth-level treasures, and the power of eighth-level treasures, but now, it is the ninth-level quality, close to the power of tenth-level. The material is really very important, and the use of high-grade spirit stones has improved the quality of the talisman by as much as three levels, of course, this has to have Yang Tianwen's heart refining pill fire to be able to achieve this kind of accurate re-refining without hurting the talisman itself. Once the utensils are formed, it is difficult to lift them again, otherwise the slightest carelessness may lead to a bamboo basket to draw water, and it will be empty. Of course, there are some refining masters who can grasp this moderation very well.

Yang Tianwen put away his flying knife, closed his eyes and recovered his innate purple qi, and carefully checked the knowledge in the "Dan Dao Chapter", in fact, Yang Tianbu has learned almost all these theoretical knowledge, but it is the first time to do it, so he carefully review it again.

To refine the pill, you must first learn to distinguish the medicine and know the various medicinal surnames of the medicinal materials well. Mortal physicians rely on experience and the appearance of medicinal materials, while Yang Tianwen does not need to be so superficial. A method of identification, you can perfectly grasp the medicinal surname of the medicinal materials, of course, the more skilled this identification technique is, the higher the level of the elixir that can be identified, and the clearer it will be identified. This Dan method can be said to be known to everyone in the primeval period, but there are really few specializations. And now, Yang Tianwen doesn't know if this Dan method has been handed down. Yang Tianwen's practice of "Purple Night Treasure Record" is the top method of the ancient times, and the identification technique recorded on it naturally cannot be a popular product, it has a nickname, which is called the divine discernment, and the most proficient in this way is the legendary Taiqing sage, all things in the world, whether visible or invisible, can be distinguished, and one law is ten thousand laws. Yang Tianwen's Divine Discernment Technique was just a beginner, so naturally it was impossible to reach such a high level, and it was enough to use it to identify these herbs.

The newly obtained several copies of the Dan prescription were studied, and then compared with several primary Dan prescriptions with the same effect in the "Dan Dao Chapter", in terms of the final medicine surname, the effect of the two after refining is the same, although the elixir of the formula is different, but in terms of the overall medicine surname, it is the same, but the difference is that the original Dan prescription is used as a blend of yin and yang, and most of the primers for neutralizing the medicinal effect have been replaced with demon pills. Yang Tianwen found out with divine discernment that the spiritual power in the demon pill is very pure, although there is a demon surname in it, and humans cannot take it directly, but if it is used as a medicinal material, its medicinal surname can be used as an introduction to reconcile yin and yang, neutralize the medicinal effect, and purify and integrate the effects of each medicinal material. The demon pill can also be removed by adding a few other elixirs during the refining process, or by using a special refining method to remove the demon surname. In this way, several of these elixirs can be replaced. The person who invented this method must have been an amazing Dan Dao master.

However, it is a pity that the demon pill is not an elixir after all, although it can be used as medicine, but the demon pill is cultivated by demons after all, and there are some differences in it, for example, the demon pill with the surname is the best as a medicine, but among some of the pills, the demon surname is too strong, the spiritual power is not pure, and it will fail to use it in medicine. However, this restriction can be reconciled by controlling the fire throat, strengthening the medicinal power, and attaching spiritual power, or it can be avoided by adding a few precious elixirs of the golden oil type to increase the success rate, of course, this is a test of the alchemist's skills.

Yang Tianwen took out the Dan furnace and concentrated on the real force, the Dan furnace that was originally a big palm grew in the wind, and became several times larger, Yang Tianwen was very happy, not bad, not bad, it can also become bigger and smaller, although it can not be made bigger and smaller without limit, but there are more choices, and there is no need to buy another Dan furnace of different calibers.

Under normal circumstances, the larger the Dan furnace, the more difficult it is to control the fire throat, but the general popular pills must be refined in batches and batches, and a large Dan furnace must be used. However, sometimes, to refine some more precious elixirs, you need a small Dan furnace to control the fire throat and avoid mistakes.

The large Dan furnace has a lot of medicinal materials and a large number of pills to refine, saving time and effort. Small Dan furnaces also have their own advantages. Yang Tian asked whether the elixir in his hand was too much, and whether it was too little, so he had to use a moderately sized Dan furnace. For the first time refining, of course, it won't be too big, and a little smaller is the best, test it, and practice your hands.

This alchemy, the order and time of putting medicinal materials are also particular, Yang Tianwen wants to practice this, as for the most critical issue of the fire throat, because of the existence of the heart refining pill, it is very easy. Yes, the Heart Refining Pill Fire naturally cannot only be used for refining weapons, and another function that cannot be ignored is alchemy. Otherwise, it wouldn't have been recorded in the "Dan Weapon Secret".

At the bottom of the Dan furnace there is an eternal magic circle similar to a large mirror, this formation, Yang Tianwen will also, its function is to connect the fire of the center of the earth, or to continue the true fire in the body of the cultivator, through which the fire can be transmitted into the Dan furnace for uniform heating, it also has the effect of saving effort, through which the consumption of true fire in the alchemist's body will be greatly reduced. The inside of the Dan furnace is also engraved with a formation, which has the effect of reinforcing the defense against fire.

Yang Tianwen continued the heart refining pill fire in his body, in fact, he passed the pill fire in his body into the Dan furnace magic circle, and through the Dan fire, he knew everything in the Dan furnace well, which was the magical function of the heart refining pill fire.

There was no need to explain the process, Yang Tianwen strictly followed Dan Fang's description, and let go of the elixir step by step for refining. Half an hour later, Yang Tianwen put away the fire in time, and after waiting for a while, a burst of medicinal fragrance came from the Dan furnace, and the Dan was completed. A rookie like Yang Tianwen, who succeeded in alchemy for the first time, is afraid that he can only be described as a genius.
