The next day, when Xiao Yu came to the Alchemy Hall, Elder Xu saw his smiling and radiant appearance, and asked in his heart, "Disciple, but have you gained enlightenment today?"

Hearing the master's inquiry, Xiao Yu immediately replied: "Back to the master, the disciple has indeed gained, the disciple has realized the way of mutual growth and restraint between the five elements of the elixir and the medicinal properties of the elixir when the disciple is fused, I don't know if this is the gist of the master's disciple's enlightenment!"

After hearing this, Elder Xu smiled and said, "Then you come to answer as a teacher, why can't the green vine flower be directly fused with the thorn grass?"

Xiao Yu replied: "The green vine flower is wood, and the thorn grass is gold, the two are compatible with Jin Kemu, and the essence of the green vine flower must be greatly damaged, so it cannot be directly fused!"

Then Elder Xu asked again, "The Spirit Bone Grass is the same as a tree, but why did it have to merge with the Thorn Grass first?"

Xiao Yu replied unhurriedly: "The spirit bone grass contains two essences, one wood and one water, the wood attribute essence is highly poisonous, and what is needed when refining the pill is the essence of the water attribute, so first fuse with the thorn grass, and use Jin Kemu to eliminate the toxicity, here is the principle of the five elements of mutual restraint!"

Then Elder Xu asked a lot of questions, all of which were about the theory of the five elements being mutually reinforcing and restraining each other, Xiao Yu could answer them fluently, and Elder Xu said in a laughing manner: "How fortunate the old man is, he has such a high level of understanding, and he is fortunate to win the sky!"

After Elder Xu had laughed enough, he stroked Xiao Yu's hair and said, "Good apprentice! Now you have learned the theory of alchemy, and the next few things are some valuable experience at the bottom of the box for the teacher, but you have no way to learn it now, in the future, you will first refine a grade of pill here for the teacher, and the teacher will suggest that you refine the Gathering Spirit Pill, and hone your refining skills, and when the teacher thinks that he can teach you the following theories, he will teach it to you!" After speaking, he took Xiao Yu to a medicine garden.

Elder Xu pointed to the medicine garden and said to Xiao Yu: "Apprentice, in the future, you can come to the medicine garden to pick the elixir, you can take the elixir in the medicine garden as you like, hone your skills, and strive to truly master the skills taught by the teacher as soon as possible!"

Xiao Yu looked at the elixir in the garden, these are all good materials that are more than fifty years old! These are all valuable goods when they are outside! Master, his old man, let him use them casually, Xiao Yu couldn't help but be moved in his heart, it seems that Master really treats himself as a parent! In the future, he will definitely repay this kindness.

Although Xiao Yu was grateful in his heart, he didn't want to take such a big advantage from the master for no reason, so he said: "It is a great kindness for the master to pass on the disciple's mastery, how can the disciple still use the master's elixir!

Elder Xu was not angry, but admired Xiao Yu's character very much, took Xiao Yu's little hand and said, "Do you know who are the richest people in the Immortal Cultivation Realm?" Today, I will tell you that it is not the heads of those major sects, nor the alliance organizations of those merchants, but an accomplished alchemist like us, do you understand?" Although the alchemy technique of being a teacher is not the top existence in the world of cultivating immortals, the wealth accumulated over the years is also unimaginable, and the teacher is destined to have no chance with the Great Dao in this life, and it is originally a few decades of longevity, but with you by your side, the longevity of the teacher has increased by as much as a hundred years, and now there is a possibility of going further, you give the teacher much more than the teacher gives you! It's not even a dime for a teacher, so you can rest assured that you can use it, and if you are a teacher in the future, if you really live a long life, who else can you leave all your wealth to!"

After Xiao Yu heard these words, tears flashed unconsciously in his eyes, after coming to the Dragon Phoenix Pavilion, Xiao Jiumei was the only one who made him feel like a relative, and now he also felt a father's care from the master, he quickly knelt in front of the master and said: "The disciple will live up to the high expectations of the master and hone the Dan Dao hard!"

Elder Xu also showed a look of relief on his face, and said kindly: "Get up! Let's go to alchemy! As a teacher, you still have to rely on your origin power to cultivate! Don't be sentimental here, I believe that you will be extraordinary in the future!"

Xiao Yu was not in a hurry, and after picking three points of the elixir of refining the lower grade gathering elixir in the medicine garden, he followed the master to the alchemy room, and Xiao Yu would also enter the realm of selflessness when refining the pill, so Elder Xu also sat beside him to cultivate.

It wasn't until this moment that Xiao Yu understood that people would say what to 'learn the hand', and no one would say what to 'learn the heart', it is one thing to be able to learn, and it is another thing to be able to use!

The pill refined a few days ago is also a first-grade pill, but it is easier to refine than the Gathering Spirit Pill, there are not so many types of materials, the fusion is not so cumbersome, and the mana requirements are not so high, so Xiao Yu's refining of the Gathering Spirit Pill this time is only sixty percent.

For an ordinary alchemist, such a pill formation rate is already very high, and the quality of the pills that Xiao Yu refined is obviously much better than those he has taken before, but Xiao Yu is not satisfied with his current achievements, he thinks he can do better.

So he began to refine the second material, and Zuihou really had a few more pills, but the Cheng Dan rate was only a little more than sixty percent, until Xiao Yu finished refining all the three elixirs, although there was some progress, the Cheng Dan rate still did not break through seventy.

At this time, a whole day has passed, Elder Xu didn't stay with Xiao Yu more, so he let him go back, Xiao Yu returned to the cave and was a little sullen, so he didn't play with Xiao Jiumei and sat directly on the ** and began to summarize the gains and losses of today's alchemy, he thought about it after all, he didn't find anything inappropriate, it seems that his skills are not skilled enough, and he should practice more.

Three days had passed, Xiao Yu came to the master again, this time he picked four materials from the medicine garden to refine the lower grade of the spirit pill, came to the Dan furnace and bowed to the master before starting to do alchemy.

After the refining of the four elixirs was completed, the rate of Cheng Dan still did not break through seventy, but it was already very close, so Xiao Yu went to the medicine garden to pick five points of elixir, and was going to take it back to continue contacting, Elder Xu didn't say anything, just told Xiao Yu not to patronize the alchemy, and his cultivation should not be wasted, so he let him go back.

After Xiao Yu returned to the cave, he didn't pause at all to recover his mana and began to continue alchemy, now his skills are already very proficient, so the alchemy is also faster than before, and the five-point elixir was consumed in only half of the night, and the progress is indeed not great.

There is no elixir to continue alchemy, which makes Xiao Yu a little annoyed! Seeing Xiao Yu like this, Xiao Jiumei's round eyes rolled, and she took out a lot of elixirs like offering treasures, Xiao Yu was so excited when she saw these elixirs, he hurriedly got busy again, and he didn't care where the little girl got these elixirs.

It turned out that the little girl saw Xiao Yu's sad appearance all day long, and she didn't know that he was because the Cheng Dan rate was not high, and she thought that the elixir for practicing her hands was not enough, so he took advantage of Xiao Yu's time to go to the alchemy hall, and went to Baizhangping alone, and bought all the materials for refining the spirit pill in the stall at a great price.

Xiao Yu refined the materials of the five-point elixir again, and finally made some progress, but the more he went to the back, the more the progress was minimal, he was not completely immersed in alchemy, he stopped alchemy after dawn, and after freshening up, he adjusted his mentality and came to the practice room to practice**, he believed that the master had always instructed him not to waste his cultivation, and he must have his reason.

Now that there is enough elixir material support from the master, and after returning home, there is another virtuous helper, Xiao Yu's alchemy skills are improving bit by bit in the hard practice.

Three months is not long or short, Xiao Yu finally increased the Cheng Dan rate to eighty percent, but sadly found that no matter how hard he practiced, there was no way to improve after all, and he couldn't even refine one more pill, Xiao Yu knew that this should be the limit of his current stage.

Xiao Yu came to the master again, Elder Xu said: "Cheng Dan rate has reached eighty?" Seeing Xiao Yu nodding yes, Elder Xu twisted his beard and said: "Well, it should be your limit, you may still be confused, I don't know where the mistakes are, in fact, the master told you that you have not made any mistakes, and your skills have been polished perfectly, but your current cultivation is not high, and your mana is not pure enough, so you will not make any progress in practice!" Now you should know the intention of being a teacher so that you can't waste your cultivation!"

After finishing speaking, Elder Xu took out two more jade bottles in his hand and said to Xiao Yu: "Apprentice, these are two bottles of high-grade Gathering Spirit Pill, the teacher knows that although you are in the middle stage of Qi training, but the medium-grade pill is no longer useful to you, there are two hundred pills in each bottle here, after you go back, give your little wife a bottle, and leave a bottle for yourself, this bottle of pill is enough for you to break through the late stage of Qi training, and when the time comes, you will come to find a teacher, you will not use it to be a teacher during this time, you have to retreat for a period of time! When you need an elixir, you can come to the medicine garden at any time to get it, go!"

Xiao Yu heard that it was a top-grade pill, and there were so many, his heart was already happy, and after taking the pill, he asked suspiciously: "Master, don't you need the assistance of your disciple's origin power now, can you already re-condense your mana and prepare to attack the Jindan Dao!" Elder Xu smiled and said nothing, just waved his hand to let Xiao Yu leave, at this time, it was already tacit, Xiao Yu was also happy for the master, and said goodbye to the master.

After returning to the cave mansion, Xiao Yu held the jade bottle in his hand and shook it in front of Xiao Jiumei's eyes and said, "Come to the little beauty, laugh!" But unexpectedly, the little girl pouted and said: "While you go, the Gathering Spirit Pill you refined is useless to others!

Xiao Yu was happy to hear it, it turned out that the little girl thought that it was refined by herself! So she said: "Yo! I didn't see it! I lost my temper! I didn't even pay attention to the high-grade Gathering Spirit Pill, so I'll give it to someone else!" Hearing Xiao Yu say the high-grade Gathering Spirit Pill, the little girl immediately snatched the jade bottle from his hand and said, "What? Shangpin Dan, you have refined it into a high-grade Dan! Who said no, who else do you want to give it to!" After speaking, she glared at him.
