The sixth senior brother saw that the little ninth sister handed over the jade bottle to his wife, so he said eagerly: "Nine girls, you give all the pills to your senior sister, and you won't cultivate yourself!"

Xiao Jiumei smiled at Xiao Yu at this time and said, "That guy feeds me with pills like a pig every day, don't worry, there won't be no pills to cultivate by his side, you can rest assured that you can cultivate!"

Only then did the sixth senior brother suddenly say: "Yes, it's senior brother, I'm too worried, how can the Daoist of the little Danxian lack pills to cultivate! Then your senior sister and I won't be hypocritical, and we will accept it with peace of mind!"

Xiao Yu chatted with the two of them for a while, but there were too many people waiting for alchemy outside, Xiao Yu couldn't delay for too long, and the sixth senior sister was naturally embarrassed to disturb Xiao Yu for too long, and they also wanted to go back to retreat and practice sooner, so they also said goodbye and left.

Xiao Yu began to refine the pill again, and now Xiao Yu has stopped refining the materials for refining the medium-grade Gathering Spirit Pill, and now Xiao Yu has a ninety percent success rate in refining the middle-grade pill, and it will not grow anymore, so now he is focused on improving the success rate of the high-grade pill.

Only refining the top grade pill, Xiao Jiu Mei doesn't need the pill to cultivate now, she can only rely on Xiao Yu to cultivate when she enters the realm of selflessness when she is refining the pill, although she does not take the pill quickly, but it is already very fast, and she spends her days in such peace.

Three years have passed in a blink of an eye, and now Xiao Yu has turned thirteen years old, and Xiao Jiumei is already a fifteen-year-old girl, and her appearance has become much more coquettish, Xiao Yu often looks a little daze unconsciously.

On this day, when Xiao Yu was cultivating in alchemy, a firelight came to his side, Xiao Yu hurriedly took it in his hand, and suddenly a familiar thought entered Xiao Yu's spiritual sense, making Xiao Yu's voice both nostalgic and excited sound in Xiao Yu's mind.

The voice said: "Apprentice, the master has already left the customs, you can come to see the master, and the master can't wait to see the demeanor of the little Danxian!

Xiao Yu's excited body was trembling, he had already regarded the master as his own relative, there had been no news of the master in the past three years, it would be a lie to say that he was not worried, and now that he finally got the call of the master, he was naturally overjoyed.

Xiao Yu hurriedly finished refining the pill in his hand, and then said to Xiao Jiumei, and couldn't wait to run towards the alchemy hall, even ignoring the people standing at the door of the cave.

After coming to the Alchemy Hall Master's Cave Mansion, Xiao Yu couldn't help but have tears in his eyes with excitement, seeing the master standing in front of him with a red face, Xiao Yu couldn't control his emotions for a while and threw himself into the master's arms, and tears flowed out of his eyes.

Elder Xu is also hugging his beloved disciple, with a relieved smile on his face, Xiao Yu has grown a lot taller in the past few years, and he is almost reaching Elder Xu's shoulders, looking at the beloved disciple in his arms who is about to catch up with his own height, Elder Xu's heart is also surging.

The master and apprentice chatted for a long time, and after Xiao Yu relieved all his worries and thoughts about the master in the past few years, Elder Xu began to talk about this retreat, and at this time Xiao Yu noticed that although the master is still cultivating to build the foundation of the Great Perfection, it seems that he is about to break through to the Jindan stage at any time.

After a while, Elder Xu said to Xiao Yu: "Apprentice, you have also noticed that the master's cultivation has reached a critical point now, and there is not much time left before the breakthrough, and after the master will teach you all the alchemy skills, the master will also find a place to form a pill, so then you have to be more attentive and memorize all the skills taught to you by the teacher, so that the master can rest assured to go to the pill!"

Xiao Yu listened to Master's words and was about to speak, but Elder Xu waved his hand and said: "Your heart is fluctuating today, and it is not suitable for learning the new way of alchemy, so you go back first, and explain to your wife, in recent months, you have been cultivating with the teacher, so that she is mentally prepared, but don't worry, and then you will come to see the teacher tomorrow!"

Xiao Yu also knew that what the master said made sense, and now that he was restless, it was indeed not the best time to study, so he obediently gave the master a salute and returned to the cave.

At this time, the people in front of the cave had already driven Xiao Jiumei away, she knew that Xiao Yu went to see the master, and then she had to focus on learning a more advanced way of alchemy, and there would be no leisure time for them to alchemy, so let them not come again for the time being.

After Xiao Yu returned to the cave mansion, she told her about the cultivation she was going to practice with her master in the next few months, although Xiao Jiumei was reluctant, she had been together for a few years, and she had never been separated, she was used to living by Xiao Yu's side, and now she was naturally reluctant to be separated for so long.

But she also knew that this cultivation was extremely important to Xiao Yu, so she naturally didn't dare to stop it, and she also pretended to be very happy to dress up Xiao Yu, and the next day she personally went to the door of the cave to see Xiao Yu off, at this time, Xiao Jiumei really looked like a wife.

After Xiao Yu came to Master's Cave Mansion, Elder Xu didn't talk too much, after all, time was pressing, and although he was in retreat during this time, he still got a lot of news from his old friends after leaving the cave.

In fact, even if it is a retreat, he will not ignore this good apprentice who is rare in a thousand years, and he asked his friends to help secretly take care of Xiao Yu long before the retreat, so although Xiao Yu's current situation cannot be said to be thorough, he still knows a little about Xiao Yu's current alchemy level!

As soon as Xiao Yu arrived, he handed Xiao Yu a low-grade Gathering Spirit Pill, and then asked, "Disciple, look at how this pill is, is there a way to turn him into a medium-grade pill!"

Xiao Yu took the pill and looked at it carefully, but he didn't find anything special, this was an ordinary low-grade spirit pill, so Xiao Yu shook his head suspiciously and said: "The apprentice can't, the master must have a deep meaning when he asks like this, but the disciple hasn't understood it for a while, please give the master advice!"

Elder Xu said with a smile: "Do you know why the pill is divided into four grades, why the lower grade pill is the lower grade, and the middle grade pill is the middle grade, what are these judgments based on!"

Xiao Yu thought for a while and said: "The level of the pill is distinguished according to the amount of impurities and spiritual power contained in the pill, the less impurities and the more spiritual power, the better the quality of the pill!"

Elder Xu asked again: "Then you said that two pills of the same size, when the elixir was purified, the impurities had been removed, why would there be more impurities and aura after refining the elixir!"

These Xiao Yu also encountered these when refining the pill, so Xiao Yu said: "The material of the lower grade pill is not enough, and it is easy to form impurities when it is fused, and the aura contained in the elixir is also limited, so there are many impurities, and the spiritual power is limited to become the lower grade pill, but when the elixir materials above the middle grade are fused, the ability of the elixir to withstand fire is slightly stronger, so it is not easy to produce impurities, and the spiritual power contained in the elixir is also enough, so it is easier to refine it into a high-grade elixir!"

After hearing Xiao Yu's answer, Elder Xu nodded and said, "It seems that you have noticed that impurities will be produced when the materials of the lower grade pill are fused, and you also know that the more spiritual power content, the less likely it is to produce impurities, so have you ever thought of using the lower grade pill as an elixir material to refine the middle grade pill!"

Treating Xia Pindan as a material for refining Zhongpindan, this sentence really shocked Xiao Yu's whole person, how is this possible, I have never heard of this kind of yes!

But Xiao Yu thought about it carefully, this is really not something that cannot be realized, the reason why there are too many impurities in Xia Pindan, it is because it is inevitable when it is fused, but after becoming a pill, it will not be fused after it is carefully melted with fire again, so as long as the impurities are separated, the remaining pills will naturally have no impurities, and the quality of the pills will naturally become better without impurities.

But to become a higher-level Zhongpin Dan in one fell swoop, this is naturally a bit unrealistic! Could it be that the master has a way to do it, yes, if the master has no way to do it, he will naturally not bring up this matter, it seems that the master is going to teach himself the ability to press the bottom of the box today.

Elder Xu waited for Xiao Yu to think alone for a while before he said, "Can you understand the key to this, is my method feasible?"

Xiao Yu hurriedly replied: "The disciple has already understood that the pill can be purified twice, but after all, the spiritual power of the middle-grade pill is much more condensed than the lower-grade pill, and it is probably not enough to purify and remove impurities, Master, you must still have the method of condensing the pill, otherwise the promotion of the pill is really not easy to achieve!"

Elder Xu hurriedly smiled: " Good apprentice, or as smart as before, this has been guessed, what the master wants to teach you now is the law that can condense the elixir, the teacher used to say that you want to cultivate to achieve the great perfection of the late stage of qi training before passing on to you the stunt at the bottom of the box, it is because of this set of law decisions, this law is called Xuan Condensation, only to reach the late stage of Qi training The Great Perfection can be cultivated, now sit cross-legged and wait for the teacher to teach you the mantra, remember that this method must not be passed on, even if you accept disciples in the future, you can not pass it on to the disciples who do not cultivate the Dan Dao, you can remember!"

Xiao Yu hurriedly replied: "The disciple remembers Master's words today, and does not dare to disobey!"

After Xiao Yu sat down, Elder Xu stretched out a finger and pressed it on Xiao Yu's head, which was when Xiao Yu felt a burst of mental fluctuations enter his mind and turn into thousands of thin threads, and zuihou turned into a piece of scripture and presented it on the sea of knowledge.

Xiao Yu carefully comprehended this set of decisions, and unexpectedly found that this set of laws was somewhat similar to his own spring rain from the sky, both of which condensed spiritual power with the power of rotation, but the spring rain from the sky was to condense the spiritual energy of the outside world into raindrops, and the Xuan Condensation Recipe was a higher level of spiritual power in the condensation pill, and the two had the same effect, as if they were from the same source.

Of course, Xiao Yu didn't have time to delve into this matter now, because the master had already let him begin to comprehend and cultivate this set of Fa Decisions! Xiao Yu believed that with the foundation of spring rain falling from the sky, he would soon be able to practice this set of Fa Decisions.
