Soon, another month passed, and Yan Wubian was still sitting in front of the medicine cauldron, using his magic skills to control the flames with a focused expression, and large beads of sweat oozed from his forehead.

Two months later, Yan Wubian looked at a furnace of pills that smelled like burnt food, and smiled bitterly in his heart.

Time flies, half a year flies by in a blink of an eye.

In the wooden house, Yan Wubian was still sitting cross-legged in front of the silver medicine cauldron, looking at the green pill in his hand, and finally a hint of joy appeared on his face.

This Ice Condensation Pill is the only one that Yan Wubian has succeeded in in the past six months, and this is thanks to his frequent elixir making before and his rich experience.

After carefully examining the elixir in his hand for a moment, Yan Wubian seemed to have thought of something. He then used some simple secret technique to identify the ice condensation elixir in his hand.

"It's just the lowest elixir."

After the appraisal, Yan Wubian couldn't help but murmured to himself.

After entering the fairy world for such a long time, Yan Wubian has also read some basic books that introduce the system and types of pills in the fairy world. According to records, the classification of pills in the fairy world is extremely detailed, and it is not a rule of the sky at all.

The city is comparable.

Although ordinary spiritual masters use the level of application of elixirs to simply distinguish them by the level of spiritual fluid, medicinal stone, crystallization or even true elixir level. But in fact, the elixirs of each level are distinguished by the purity of the elixir.

Depending on the degree, it can be divided into low-level, ordinary and advanced elixirs.

No matter what kind of elixir is refined, it will inevitably contain some impurities that are not beneficial to the person who takes it, and they can be easily identified through various means.

Among them, low-level elixirs are those that contain more than 50% impurities and less than half the purity. Ordinary elixirs are between 50% and 70%, and advanced elixirs are between 70% and 70% pure.

into the above elixirs.

As for the elixirs that have entered the upper level, there is another classification. Those with 70% to 80% purity are called ordinary-grade elixirs, and those with 80% to 90% purity can be called top-grade elixirs.

Those with a purity of over 90% are rumored to be top-quality elixirs.

In addition, once the elixir enters the level, strange phenomena will appear on the surface, and a layer of elixir halo will appear. And the more layers of elixir halo, the higher the grade will naturally be. Therefore, even if you are not an alchemist, you can pass it.

The amount of elixir halo is used to simply distinguish the grades of high-grade elixirs.

Therefore, the same elixir has different values, and there is no comparability between advanced elixirs and ordinary elixirs. After all, the higher the purity of the elixir, whether it is the effect on the spiritual master or the resistance to medicine

, are not comparable to the latter.

Although the difference in purity is only 15%, for some special elixirs, this 15% purity is enough to make a world of difference in the effects of the elixirs.

In the fairy world, only those alchemists who refine truly advanced elixirs can be called true masters of alchemy.

Yan Wubian now thinks back to the fact that when he was refining the Soul-Reviving Xuanru Marrow Pill, there seemed to be a situation where a layer of pill halo appeared on the surface of several pills.

Of course, Yan Wubian would not think that he was the so-called master of alchemy in the fairy world. He knew very well that he had relied on refining a large amount of Fu Ling Xuan Ru marrow pill. Practice makes perfect, and he succeeded in refining that by chance.

At that time, if he was asked to refine the rest of the elixirs, it would be absolutely impossible to refine the first-level elixirs.

Although his strength has improved a lot now, the level of the elixir he needs is naturally higher, and it is more difficult to refine it. In the entire fairy world, the higher the level of cultivation, the higher the level of the elixir.

As a spiritual master, it is more difficult to find an alchemy master who can refine elixirs suitable for your own level.

If Yan Wubian hadn't been able to provide him with a large amount of alchemy materials because of the existence of his spiritual pet space, otherwise it would have been almost impossible for him to become a true alchemy master in the fairy world.

Precisely because he understood the difficulty of refining elixirs, even though what he had refined was only an elixir with a purity of about 30%, it had greatly boosted Yan Wubian's confidence.

He believed that since he had achieved success for the first time, the next time he would refine the Ice Condensation Pill, it would naturally not be too long. Moreover, as he continued to accumulate experience in refining the Ice Condensation Pill, his experience in refining the Ice Condensation Pill would also increase.

The quality of the refined elixirs will also become better and better.

Without much delay, Yan Wubian put the elixir in his hand into the elixir bottle that had been prepared. Then, Yan Wubian took out the materials again and continued to refine the elixir.

In the next two months, Yan Wubian did not end the refining until the materials for refining the Ice Ning Dan were exhausted. During this period, he successfully refined it twice more.

, the Ice Condensation Pill refined this time is still a low-grade pill.

This situation made Yan Wubian feel extremely depressed, not only because the purity of the elixir was low, but more importantly because the refining efficiency was less than 10%.

If anyone knew that Yan Wubian refined elixirs like this, everyone would be stunned. After all, not many people would spend such a large amount of money to repeatedly refine the same elixir to improve their alchemy level and the success rate of elixirs. Even if there are

With this financial resources, we cannot collect so much material.

Due to material problems, Yan Wubian had to stop refining the Bing Ning Dan, but he had no intention of stopping and was ready to start refining the Jin Gu Pills.

With the previous experience in refining the Bing Ning Dan, the process of refining the Jin Gu Pill this time was much smoother. Although they are two different elixirs, there is always something to learn from the refining method.

Only three months later, the first mortal elixir with a halo on its surface was successfully refined.

Looking at the elixir in his hand, Yan Wubian couldn't help but ponder for a while.

To be honest, he was a little surprised to refine such an ordinary elixir so quickly. As soon as his mind changed, he understood that the reason why it went so smoothly was because of the strength of this Jingu Pill.

The difficulty of refining is much easier than that of Bing Ning Dan. Secondly, I am afraid it is also related to the age of the main ingredients of Jingu Pill. After all, the longer the age of the medicine, the better the effect, and the purity of the refined elixir.

Naturally, the higher the level, the more likely it is that advanced elixirs will appear.

Obviously, if you want to refine high-quality elixirs, the materials used are also very important. Of course, this will also increase the cost of the materials. However, this is not a big problem for Yan Wubian. He needs

Yes, it is nothing more than spending more time waiting, which is definitely a very cost-effective thing.

Moreover, high-level elixirs usually have a price but no market, and everyone is competing for them. Whether they are for sale or barter, there will definitely be many people willing to pay a high price to get them.

…

Time passes, and in the blink of an eye, another two years have passed!

In the past two years, in addition to spending more than a year refining the elixir, Yan Wubian spent the rest of the time taking Jingu Pills to practice. As for the Bing Ning Dan, it directly affects the soul.
