About a cup of tea later, Cao Jing has been pulled into the secret room of the free auction house, at this time Cao Jing still can't speak, standing there panting heavily, no way, the first time he tried such a fast leap, Cao Jing almost always held his breath to move forward, even if he used his spiritual power to protect his mouth and nose, it was in vain.

"Little brother, you are finally here, we are all waiting for death, now it's okay, you take a look at this pill recipe for nourishing the pulse, familiarize yourself with it first, I hope you can refine it as soon as possible, there is no time to wait, alas!" Seeing Cao Jing enter the secret room, Wu Can, the chief medicine master of the auction house, spoke incoherently excitedly, snatched Cao Jing's arm from Feng Piaofu's hand, and came to his own face at once, and at the same time handed out a piece of brown paper to Cao Jing's hand, Cao Jing had already arranged things before he came in and said a word.

Cao Jing saw the situation here, and this chief medicine master Wu Can seemed to be very anxious, there were bean-sized sweat droplets left on his forehead from time to time, knowing that things might be really urgent, too late to talk more, Cao Jing didn't plan to talk more, the doubts in his heart can wait until the matter is resolved before asking, looking at the kraft paper in his hand, Cao Jing calmed down a few breaths, and then found a meditation cushion and sat down, and looked at it seriously.

After opening it and taking a closer look, Cao Jing knew that this Yangmai Pill was the top elixir among the second-grade pills, although it could not be regarded as the top, but it was indeed one of the more difficult pills to refine in the second-grade pills, Cao Jing was not sure to refine it at all at this time, and then took a closer look at the elixir inside, there were as many as thirty-five kinds of elixirs, and the most important of them was the three-grade elixir. This made Cao Jing feel even more difficult to start.

"Cao Jing, what do you think? It's all up to you, inside this Wuguan City. I have asked all the Yun Medicine Masters, and I have also asked them to refine them and try them, but the results of the Yang Mai Pill they have refined are not suitable, at present, you are already a second-grade Yun Medicine Master, and you are still using the Water Attribute Medicine Technique, if you can't do it......" Just when Cao Jing seriously read the Dan Fang, the voice of Feng Piao's eagerness suddenly sounded in his ears.

Ever since Wu Can handed the kraft paper to Cao Jing, Cao Jing's attention had been on this kraft paper, not paying attention to the surrounding situation. Thinking that Feng Piaoxu had gone out, he didn't expect Feng Piaoxu to keep staring at Cao Jing, and he asked so urgently, which made Cao Jing's heart couldn't help but increase the identity and importance of that patient again.

"Sister Su, have you been here all along? I have only read this pill once, and I haven't carefully comprehended it, and Sister Su, you also know that I have only been in the second grade of the medicine master for a long time, and the second grade of the pill has only tried to refine the Zhuji Dan. And the results were not satisfactory, and the other pills had not been tried, so I had very little confidence in this Yangmai Pill, which was the top of the second grade and was known as one of the most difficult pills to refine in the second grade. Or rather, there is little certainty. Cao Jing looked at the anxious wind, but he didn't mess up, and he didn't boast about Haikou or anything like that. Instead, he spoke his opinion realistically, even if it didn't help. He also did not want to make mistakes because of his own exaggeration, and Zuihou delayed the patient's treatment.

"Cao Jing. You... You really... Aren't you sure at all?" After Feng Piaoxu heard Cao Jing's return, the whole person trembled involuntarily, Zuihou sobbed uncontrollably, and his speech was intermittent, no longer as dignified as before, calmly.

"Sister Su, I won't tell you anything, I really don't have any confidence in this Yangmai Pill now, but ......" Cao Jing saw Feng Piao's expression, his heart was sad, maybe he thought of himself, Zuihou gritted his teeth and said, but he was interrupted by Feng Piao Yi only halfway through his words.

"But what? Cao Jing, say quickly, don't stop, oh, you're so anxious!

"However, if you can give me three days, no, if the time is pressing, one day, two days at most, I may be able to have fifty percent, of course, this is only my estimate, and the maximum is only fifty percent sure that can contain the Yang Mai Dan, I don't know, Sister Su, can that person wait for two days, and speak, after two days, I will only have a maximum of fifty percent certainty, and I am not 100% sure, how to choose, Sister Xu, think about it yourself!" After Cao Jing calculated in his heart, coupled with his special divine sense, if he went all out, it was not impossible to do it, but he might be subject to some backlash and the like.

"Cao Jing, you can say it earlier, don't think about it, now you are ready to refine the elixir, I will find you the most haode secret room, let Master Wucan help you, what else do you want, directly put it all forward, if you need anything, I will be able to find it for you in the shortest possible time, by the way, the elixir of refining the pulse cultivation pill, we are ready, there are a total of thirty furnaces, you can refine as much as you want, don't have a psychological burden! You write out what you need first, and I'll arrange it!" After listening to Cao Jing's words, Feng Piaoxu did not hesitate at all, and agreed directly, and the meaning of the words also explained that he would fully cooperate with Cao Jing without any delay or questioning.

Feng Piaoxu's decisiveness made Cao Jing a little stunned, after all, this matter is a matter of human life, and it seems that the injured person should be a very important person for Feng Piaoxu, and Feng Piaoxu agreed to Cao Jing without frowning, which made Cao Jing also think in his heart, it may be that they really have no choice, and although Cao Jing has little chance here, there is still a chance.

Yes, this is the idea in Feng Piaoxu's heart, hearing that Cao Jing may have refined the Yang Mai Dan, Feng Piao Fu suddenly recovered his former demeanor, and the whole person became decisive again, in fact, this is also Feng Piao Fu has no choice, so he can only do this, let Cao Jing try it, because, the highest medicine technique in the entire Wuguan City is Wu Can, but Wu Can is the fire refining method Yun Dan technique, and the Yang Mai Pill needed this time is very strict in this regard, and the pill containing fire spiritual power cannot be used, or there is a monk with advanced cultivation who is willing to take action to be able to heal the injury。

However, the minimum cultivation required is also the cultivation of the Yuan Infant Period, and the highest cultivation in the entire Wuguan City is the Jindan Period, and it is also because of the selection conference, and the highest is only the foundation building period, so it can only go to the county town to find help, but, due to the serious injury, this trip to the county city can only seek stability, and the speed is naturally much slower, and the patient can't wait for so long, therefore, this time the water refining and vein cultivation pill is needed to delay the time for the deterioration of the meridians.

A quarter of an hour later, Cao Jing was already sitting in the secret room, and there was only Cao Jing alone in the entire secret room, Cao Jing didn't have any other requirements, just asked for some elixirs of Zhuji Dan, and then entered the secret room with twenty copies of the elixir of the Nourishing Pulse Pill, this secret room is the fifth floor of the free auction hall, it is a secret room for retreat and cultivation, and all kinds of facilities are the most haode, but these are indifferent to Cao Jing. Before entering the secret room, Cao Jing asked Feng Piaoxu to send someone to the Fusheng Inn to tell Nanli about his situation, so that he didn't have to worry about it, and by the way, let him tell the City Lord's Mansion.

For the alchemy elixir, when he first became a second-grade pharmacist, Cao Jing already had an idea, in fact, it was not Cao Jing's idea, that was the idea of the elixir in the jade slip, or a secret technique can also be, that is, it can cross the level of alchemy pills, but this leapfrog also has certain restrictions, at most more than one order, and not all pills can be successfully refined, in fact, this kind of secret technique is a kind of use of divine consciousness may be more accurate, it is a kind of superposition of divine consciousness, Cao Jing has also been in a row just because he wants to participate in the selection competition, and he has not seriously tried to understand it, this time Cao Jing wants to take this opportunity to try it。

And the reason why the elixir of the Zhuji Dan is taken is to try to use it, after all, the Yangmai Dan is more important now, there are not so many elixirs for Cao Jing to practice, and the three-leaf grass cutting is also relatively difficult to see, especially in the vicinity of this Wuguan City, it is difficult to find the three-grade elixir, and only the most central place in the entire Jade Emperor Mountain Range has the output of the three-leaf grass cutting, and only some monks in the foundation building period can enter to pick some, and they must be careful.

Cao Jing alone in the comprehension of the Dan of the Yang Mai Dan, and sometimes will use the fire water lotus shiyan, and what he doesn't know is that outside the secret room, at this time, there are several people standing or sitting, or walking around, it is rare to come up once before on the fifth floor of the auction hall, at this time there are so many people, if some unknown people see it, they will definitely think that these people are noble people, in fact, yes, these people are all people with great status in the free auction house, all waiting for the results of Cao Jingyun's refining of the Yang Mai Dan, and Feng Piaoxu himself is also sitting at the main entrance of the secret room, facing the secret room, it seems that he is protecting Cao Jing。

"Don't walk around, let me sit here quietly, if you really can't calm down, go down consciously, if you let me see walking or other sounds coming out, you know the consequences, don't think I'm easy to talk, it also depends on the situation!" Feng Piaoxu, who had his eyes closed, suddenly opened his eyes, and said with a wooden mouth, the chill in his words penetrated his heart and lungs, making the people behind him who were still raising their feet and preparing to land couldn't help but tremble, zuihou gently dropped his feet, and just stood there in a cold sweat.
