Li Yuke didn't know what the two female slaves were thinking at this time, he was checking the information of the old man grass collected by the system at this time, this old man was not simple, he had a distracted mid-stage cultivation, and he was an alchemist who could refine a combined-level elixir, but what he was best at was the knowledge of medicinal materials and the identification of medicinal materials. Pen, fun, and www.biquge.info

Li Yu was a little disdainful of his ability at first, there were a few alchemists who didn't know about medicinal materials, and his ability to identify medicinal materials was also good now, and he could identify commonly used medicinal materials.

But after seeing the old man's ability to identify, Li Yu knew that a mountain is still a mountain high, and his ability to identify medicinal materials before can only be regarded as a primary school student's level, and this is the professional master's level.

The old man knew the growth environment and growth conditions of almost all medicinal materials, especially some natural and earthly treasure-level medicinal materials, and even in his memory, there were fairy grass and fairy dew, these good things with immortal characters were the real top good things in the spiritual realm.

The master of the Dacheng Realm needs to transform the true yuan in his body into an immortal yuan, so he needs these good things with immortal characters, but although the old man knows these good things, he can't refine Dacheng-level pills, and his alchemy level is still a little worse.

Since the old man Cao's knowledge of medicinal materials is a good thing, Li Yu will not let it go, and learn it immediately, the old man Cao really doesn't know how long he has lived, the amount of this information is too large, and it took Li Yu a long time to absorb this information.

After absorbing this information, Li Yu felt that he had not only enriched his knowledge of medicinal materials, but also had a better understanding of the geography of the Spirit Domain. He knew that there was a place called the Nine Shadows Sea in the Spirit Realm, and there was a kind of fairy dew there called Blue Dream Fairy Dew; I know that there is a mountain called Thorn Heaven Peak in the spiritual realm, and there is a kind of fairy grass called Life and Death Grass on the peak, the grass is divided into two leaves, one leaf can make the soul of the master of the Dacheng Realm fly away, and the other leaf can resurrect the dead......

Sighing that there are many good things in the spiritual realm, Li Yu gathered his mind and came to the alchemy room, the food should be eaten one bite at a time, and the road should be walked step by step, these too high-level things are not what he can obtain now, it is better to improve the alchemy first.

Li Yu has not practiced the alchemy he has learned, so he still starts from the distraction level, Li Yu now only has the cultivation of the early stage of the Yuan Shen Realm, and the true yuan may be a little insufficient, and it is safer to refine the distraction level elixir only with the help of earth fire.

It may be the first time refining, or it may be a little nervous, and the first time it failed not long after the furnace was opened.

It is not easy to find the reason for the failure of others, Li Yu has a system, and immediately helped him find the reason for the failure, Li Yu corrected it, and the second time, he successfully refined five Enlightenment Pills, but the quality was a little poor, only three of the five pills reached ordinary quality, and two were inferior.

After Li Yu finished refining, he did not immediately open the furnace again, but summarized his mistakes in the system, and then improved them, and when he opened the furnace for the third time, Li Yu succeeded again, directly refining eight, five high-grade, and three ordinary quality.

Subsequently, every time Li Yu had to ask the system to correct his mistakes, with the help of the system, all the pills were successfully refined, and there were more and more pills out of each furnace, and the quality was getting higher and higher, and when the last furnace was made, it had reached twelve, and the quality had also reached two perfect products, five high-quality, and five high-grade, if people knew Li Yu's improvement speed, they would definitely shock the big teeth of all alchemists.

Looking at the refined pills, Li Yu smiled on his face, saying that he was going to hand over three percent, in fact, Li Yu's pill rate was high, and he received the medicinal materials needed for two kinds of pills, so it was equivalent to only paying one percent of the pills, and the rest belonged to him, and he could continue to use other people's medicinal materials to refine his own pills.

Li Yu refined a total of twenty furnaces of two kinds of pills this time, all of them are distraction-level pills, these two pills have the representative of distraction-level pills, these two pills can be refined, then there should be no problem with other pills of the distraction level, and next time he will prepare to refine the combined-level pills.

When Li Yu came out of the Dan room, it was already the first night, there was no way, a furnace of pills took more than an hour, more than 20 furnaces, and it took him almost thirty hours.

After sleeping for a night, Li Yu was not in a hurry to hand over the pill to receive the medicine, he felt that it was better to keep a low profile, Li Yu went to the library again, he had collected all the alchemy books in the library, this time he went to collect the information of those who read books in the library, last time he only cared about reading books, and he didn't have time to collect them.

More than a month has passed, Li Yu pretended to read books in the library and collected all kinds of skill information, especially when those who read people and read books, their brain waves were extremely active, and the collection was very smooth and fast. In addition, he will go to the medicinal materials warehouse every other day, and he doesn't need to pretend to be the honorary herbs of the improved Danfang, he can directly use the Danfang that has not been systematically optimized, you must know that the medicinal materials required by the unoptimized Danfang are almost half more than the optimized ones, and every time he refines the Dan, there will be some precious medicinal materials left, and these medicinal materials are naturally put away by him.

When he was fine, he would also contact Jian Ji and Anne through a contract, knowing that the two girls had arrived in Tianya City and found an inn to live in, which was very safe, and he was relieved.

In more than a month, Li Yu had basically mastered the refining of ordinary pills at the Tribulation level, and he felt that his alchemy was almost complete, and he should be able to start refining the Crossing Erdan.

The Crossing Pills are the most special among the Tribulation-level pills, the most difficult to refine, and the Heavenly Treasures that need to be used are also the most, that is, the optimized Crossing Pills all need four-flavor Heavenly Materials-level and Eight-Flavor Earth-level medicinal materials, which is simply too luxurious, and the ones that have not been optimized are nine times more, it is simply unimaginable, how did the predecessors develop this pill, it will not be that kind of liar alchemist, right? Suddenly, Li Yu felt that his conjecture was correct, otherwise how could he use nine times more medicinal materials? It should be impossible for an alchemist who can study this level to do this, that is to say, the alchemist who came up with this kind of pill recipe is simply too greedy! It is not a little bit of greed, but nine times the medicinal materials, this is a heavenly and earthly treasure level medicinal material, and it is not easy for many people to think of one.

As for why Tang He, an alchemist who can refine a tribulation-level elixir, didn't see through this pill, Li Yuzhi didn't think it was strange, such a high-grade pill was still handed down from ancient times, how could ordinary people think that it could be optimized and streamlined, holding this pill can't refine the pill, he will only think that his alchemy level is not enough, and his alchemy level, Li Yu also knows, he can barely refine some tribulation-level pills; Looking at the medicinal materials in the Dan Fang, it is indeed used to refine the Du Erdan, I never thought that this Dan Fang could be broken down into nine Dan Fang, if Li Yu didn't have the help of the system, I am afraid that he would be at a loss with this Dan Fang.

The nine decomposed pills took three days to complete the refining, with the refining hands of the previous day, plus so many precious medicinal materials, Li Yu was careful and careful when refining, and let the system remind himself in time, so these nine pills Li Yuyu did not fail once, all succeeded, and the nine furnace pills obtained a total of nine perfect products, seventy-one high-quality products, twelve high-grade pills, a total of ninety-two, which simply exceeded Li Yu's own expectations, and according to the agreement, he only needed to give three to the Iron Fist Martial King, which was simply a huge profit!

Li Yu didn't immediately take this pill to the Iron Fist Martial King, he found that although the nine pills were all made of the Dou'er Dan, there were some subtle differences in the pills, and for such a high-grade pill, Li Yu couldn't tell what the impact of this difference would be, fortunately, after asking the system for help, the results obtained were still gratifying, and did not affect the efficacy of the medicine.
