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

When he returned to the room, Yang Tianwen first set up a simple sound insulation formation, then took out a few of his talisman flying knives, and then took out a few top-grade spirit stones to refine the heart-refining pill fire, integrate it into the flying knives, and ban the inferior parts of it. However, it can only improve the quality of a few flying knives, but the power is not greatly 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 about eighth-level treasures. Now, it is the quality of nineth-level treasures and close to tenth-level. The materials are indeed very important. The blending of top-grade spirit stones has increased the quality of the talisman by three levels. Of course, it is necessary to use Yang Tianwen's Heart Refining Pill Fire to achieve this precise re-refining without hurting the talisman itself. Once the utensil is formed, it is difficult to improve again, otherwise if you are not careful, you may get water from the bamboo basket and be in vain. Of course, some masters of refining can master this moderation well.

Yang Tianwen put away his flying knife, closed his eyes and recovered the innate purple qi, and carefully checked the knowledge in "The Alchemy Chapter". In fact, Yang Tiante has learned almost all of these theoretical knowledge, but it is just the first time he has done it, so he carefully reviewed it.

To refine pills, you must first learn to distinguish medicines and understand the various medicinal properties of medicinal materials as you know. Doctors in the mortal world rely on experience and appearance of medicinal materials, while Yang Tianwen does not need to be so superficial. A method of identification can perfectly master the medicinal properties of medicinal materials. Of course, the more proficient this identification technique, the higher the level of the spiritual medicine, the clearer it will be. This alchemy method can be said to be in ancient times, but there is really little specialization. And now, Yang Tianwen is not

I know if this alchemy method has been passed down. The "Zixiao Baolu" practiced by Yang Tianwen is a top ancient magic trick. The identification technique recorded on it is naturally impossible to be popular. It has a separate name and is called the magic discrimination technique. The most proficient in this is the legendary Taiqing saint. All things in the world can be distinguished regardless of their physicality. One method can be understood by all laws. Yang Tianwen's magic discrimination technique is just a beginner, so it is naturally impossible to reach such a high level. It is enough to identify these herbs.

I studied several newly obtained pill recipes and compared them with several primary pill recipes with the same effect in the "Pan Dao Chapter". In terms of final medicinal properties, the effect they have had is the same after refining. Although the spiritual medicines in the formula are different, they are the same in general medicinal properties. However, the difference is that the several flavors in the original pill recipe are used to harmonize yin and yang, and the introductions for the effects of the pills are mostly replaced with demon pills. Yang Tianwen used the magic technique to check that the spiritual power in the demon pill is very pure, although

However, there is a demonic nature in it, and humans cannot take it directly. However, if it is regarded as a medicinal material, its medicinal properties can be used as a primer to harmonize yin and yang, neutralize the medicinal effects, and purify and combine the effects of each medicinal material and exert it. During the refining process of demon elixir, a few other elixirs can be added to remove the demonic nature, or to remove it with special refining methods. This can replace several of the elixirs and alchemy. The person who invented this method must be a stunning master of alchemy.

However, unfortunately, the demon pill is not a spiritual medicine after all. Although it can be used as a medicine, there are some differences among the demon pills after all. For example, the neutral demon pill is the best as a medicine guide, but some medicine pills have too strong demonic nature and impure spiritual power. If used as medicine, it will fail if it is used as a medicine. As the saying goes, a slight difference is a thousand miles of mistakes. This is also the reason for the huge increase in the failure rate of alchemy. However, this limit can be harmonized by controlling the fire throat, strengthening the medicinal power, and increasing the spiritual power. It can also be avoided by adding several precious elixir-type spiritual pills to increase the success rate. Of course, this tests the skill of the alchemist.

Yang Tianwen took out the alchemy furnace and poured his true strength. The alchemy furnace that was originally the size of a palm grew in the wind and became several times larger. Yang Tianwen was very happy and was very happy. It was good, good, and it could also become larger and smaller. Although it could not be increased without limit, there was too much choice in terms of choice, so there was no need to buy another alchemy furnace of different diameters.

Generally speaking, the larger the elixir, the harder it is to control the fire throat. However, if the general popular elixirs are refined in batches, a large elixir must be used. However, sometimes, when refining some more precious elixirs, a small elixir is required to control the fire throat and avoid errors.

A large alchemy furnace contains more medicinal materials and the number of elixirs refined is also saved, saving time and effort. A small alchemy furnace also has its own advantages. Yang Tianwen said whether there are too many spiritual medicines in his hand or not, so he has to use a moderately sized alchemy furnace. It is the first time to refine it, of course it will not be too large. It is best to try it and practice it.

The order and time of refining the alchemy are also given. Yang Tianwen needs to practice this. As for the most critical issue of fire throat, it is easy to refine the heart pill. Yes, refining the heart pill fire naturally cannot be just used to refine weapons. Another function that cannot be ignored is alchemy. Otherwise, it would not have been recorded in the "Secret Explanation of Alchemy Tools".

There is an eternal magic array similar to a large mirror at the bottom of the alchemy furnace. Yang Tianwen also has this formation. Its function is to attract the fire from the center of the earth or to connect the true fire in the body of the cultivator. Through it, the firepower can be transmitted into the alchemy furnace and heated evenly. Its other function is to save effort. The consumption of the true fire in the alchemy body will be greatly reduced. There are also formations engraved inside the alchemy furnace, which has the effect of strengthening defense and fire prevention.

Yang Tianwen continued the heart-refining elixir fire in his body, which actually means transmitting the elixir fire in his body into the alchemy furnace array, and knowing everything in the alchemy furnace through the alchemy fire. This is the magical function of the heart-refining elixir fire.

There is no need to explain the process. Yang Tianwen strictly followed the elixirs and released the spiritual medicine step by step to refine it. Half an hour later, Yang Tianwen closed the fire in time. After waiting for a while, a burst of medicine fragrance came from the elixir furnace, and the elixir became. A rookie like Yang Tianwen who succeeded in the first elixir was probably only described as a genius.
