Yuan Wei followed to the alchemy pharmacy in a daze, not knowing what Lu Xuan was going to do at all.

Lu Xuan closed the door and asked with a serious expression, "You can refine the Condensation Pill, right?"

Yuan Wei replied honestly: "Yes, it will be last year." It's just that the rate of Cheng Dan still needs to be improved, and it can't keep up with the full-time alchemists of the big sects. ”

Lu Xuan clapped his hands and said with a smile: "That's fine!"

Yuan Wei looked at him confused, not knowing how to answer.

Lu Xuan's expression became serious and said, "From today onwards, you put down all the other things at hand. First of all, I will find a way to refine an elixir that makes the user have a special feeling, and the actual effect is similar to that of the Condensation Pill. ”

Yuan Wei pondered for a long time before he said, "What does this special feeling feel like? I have only tried the normal formula, and I have never tried to configure a new formula by myself." ”

Lu Xuan also scratched his head a little: "It is important to make the user feel that he and Condensation Pill are two different pills." ”

Yuan Wei said with some embarrassment: "The requirements of the head of the sect have to create a new refining method, and I have only been studying the pill for a few years, so I am afraid it will be difficult to do it." ”

Lu Xuan paused, indeed, this requirement is too high for a beginner. It is important to know that the classic elixir formula like Condensation Pill has been continuously improved by countless senior alchemists in history, and the best balance has been achieved in terms of efficacy and material cost. Therefore, if you want to improve its formula and increase its efficacy, it is by no means something that an ordinary alchemist can do.

But what I need doesn't have to be the best effect at the minimum cost, is it? As long as it can be distinguished from ordinary condensation pills and have a unique scent. According to the intended use, it would not hurt if the cost of this pill was much more expensive.

As for why it is Condensing Dew Pill, because this is the lowest level of elixir that can increase the cultivation speed of immortal cultivators, it can be said to be one of the most widely used pills in the Qi refining period, and the cost is also very low.

Thinking of this, Lu Xuan said to Yuan Wei: "If you don't count the cost, can you refine it?" as long as it has a unique aura that can distinguish it from other pills. ”

Yuan Wei looked ashamed and said: "Boss, my subordinates have ordinary talent in refining medicine, and they have never tried to refine without following the formula. So I'm ashamed, I'm afraid my subordinates won't be able to meet the requirements of the head. ”

Belch......

Lu Xuan groaned. There is a shortage of talents in this sect now, otherwise Yuan Weilai would not be allowed to serve as the master of the Alchemy Hall, so he can't blame the other party, and he has to comfort him.

"It doesn't matter. This is already difficult, and it is estimated that it will only be possible for a senior alchemist to do it. You can continue to improve in the future. ”

Yuan Wei nodded hurriedly. He was really not satisfied with his ability, so he racked his brains to satisfy the master's thoughts.

"My subordinates suddenly had an idea, but I didn't know if it was feasible. Yuan Wei said in a hurry.

Lu Xuan said in an encouraging tone: "I listen, you speak boldly." ”

Yuan Wei swallowed his saliva and said, "When my subordinates used to learn medicine refining with Elder Yang, they often saw that every time Elder Yang tried a new formula, no matter whether the result was good or bad, he would record the results in a notebook. It is said that the book was left by the alchemy elder from earlier, and over time, the book was almost full. ”

Lu Xuan's spirit was shocked, and he hurriedly said, "Good idea! Elder may have tried a refining method that is different from the standard formula before. Hurry up and find it!"

Yuan Wei rummaged through a large cabinet in the alchemy hall for a long time, and finally found a thick book.

Lu Xuan went up to take a look, opened the book, and saw that the paper inside had turned yellow, obviously some age.

From the first page of this book,It's a scribbled handwriting record of the alchemy experiment.,As for the owner of the writing.,There's no signature on it.,It's no longer testable.。

On a certain day in a certain month, twenty pills of rest were tested.

Try to replace the main material with three parts of green kozi.

Refining ten times all failed, and the Dan was abolished.

On a certain day in a certain month, ten rejuvenation pills were tried.

Try cutting back half of the red peony root.

Refining ten times, five pills.

The medicine child tried the pill, and the recovery effect was only a quarter of the original formula.

On a certain day of the month......

The records of this book are very non-standardized, and they are not distinguished by different pills at all, but are directly mixed together in order. The only order seems to be that the older the alchemist, the higher the record. Because Lu Xuan directly turned to the end, he immediately saw the handwriting of the previous generation of Elder Yang. In terms of quantity, the older the alchemist, the more records there are, and the lower the number, the fewer records there are. For example, Elder Yang's handwriting is less than two pages, and there are no more than a few experimental records. And the previous records often involve some pills that can only be refined during the foundation building period, while the later ones, such as Elder Yang, have all recorded common pills that can be refined during the Qi refining period.

It is estimated that the further the future, the poorer the Purple Thunder Gate becomes, so that gradually the exploratory experiments cannot be done. Lu Xuan sighed in his heart.

The two searched for a few hours, and finally found all the experiments related to Ning Lu Dan in the book.

There are thirty-four articles in total, and none of the conclusions in the book are useful.

Among them, there are twenty results that are all wasted pills.

There are seven results: the effect of the refined elixir is much, much weaker than the original formula, and it is almost useless.

There are four results that the effect of the refined elixir is similar to the original formula, but when you look at the materials, the price is at least several times. This is clearly not in line with the original intent of the experiment. It's too expensive, it's nothing special, and it's useless to Lu Xuan.

The remaining three results showed that the effect was similar to the original formula, and the materials were not expensive, but all had significant side effects.

One of them will cause the user's qi sea to become turbid, so that the cultivation speed will be greatly reduced for a long time to come.

The second is to cause redness and swelling all over the user, which lasts for several days.

The third is to cause the user to fall into an ice cave as cold for several hours, during which time it seems to make the consciousness clearer. However, it is also written in the record that at that time, the alchemist found a few disciples to take it every day, which lasted for a month. As a result, he was embarrassed to find that the cultivation speed of these disciples in this month was no different from that of those who had taken the Ordinary Condensation Pill. Since the material is still fifty percent more expensive than the normal formula, the alchemist sadly and angrily came to the conclusion that this recipe is absolutely useless, and refining it is purely harmful to others and oneself.

Lu Xuan repeatedly researched the third formula with side effects, and felt that it was very suitable for his needs.

This side effect was really special, at least Lu Xuan had never heard of it on any pill before. The cost is also okay, on average, there is only about one spirit stone for every ten pieces, which is not too high compared to the price I plan to sell. And there is no other harm in taking it, there will be no accidents.
