Xie Qianqiu happily said: "Of course, we can refine another furnace. Don't say one furnace, even if it's several furnaces, it's also possible." As he spoke, Xie Qianqiu had already taken out a portion of alchemy materials from his storage ring, apparently intending to refine another furnace.

  Ye Tianfan said: "Alright then, let's start now. But first, let me make one thing clear - if I don't find anything, you can't blame me!"

  "Don't worry, how could I blame you? I haven't even had time to thank you yet. Besides, you're already a master alchemist now, and after this trial, you'll be the sect's elder. By then, there will be even fewer people who dare to bully you." Xie Qianqiu said with an expression that could charm the soul out of someone.

  Ye Tianfan saw the appearance of his master's sister and didn't say much, so he said: "Since that's the case, let's get started then. I also want to see where you went wrong in your elixir refinement failure."

  When he saw Ye Tianfan start, Xie Qianqiu didn't waste any words and directly poured true fire and true yuan into the dan furnace, slowly heating it up.

  Ye Tianfan also sank his divine consciousness into the alchemy furnace at this time, silently observing and hoping to find out why his master sister couldn't refine the elixir successfully.

  Firstly, the medicinal power of the alchemical elixir was transformed into a liquid medicine. Ye Tianfan discovered that his senior sister had done an excellent job, at least much better than himself, and her control over the firing process was also very precise.

  This first step was done very well by his own master sister, Ye Tianfan knew that the reason why his master sister couldn't refine it successfully shouldn't be here, so Ye Tianfan continued to observe.

  The second step is to merge the medicinal liquid. Yè Tiān Fán thought that the problem most likely occurred here, because most people got stuck here and could only become a mid-grade alchemist.

  The result was a great disappointment for Ye Tianfan, because his own sister had successfully merged, which means the problem did not lie in the fusion pill.

  Could it be that it appeared in this step of refining the elixir? Ye Tianfan thought to himself, but he didn't think there was a high probability of that.

  Just as Ye Tianfan was thinking about where the problem lay, a loud "bang" interrupted his train of thought, and Xie Qianqiu's elixir had exploded in the furnace once again.

  Qian Qiu said angrily: "It's really hateful, another failure in refining, Tian Fan, have you found out the reason for my refining failure?"

  "Ah, Shijie, I don't see anything wrong with your alchemy process. Whether it's refining the medicinal materials into a liquid or fusing the elixir, there doesn't seem to be any mistakes. As for the elixir's potency, that's even more unreasonable." Ye Tianfan said hesitantly.

  "Goodness! You've said so much, have you found out the reason or not?" Xie Qianqiu asked anxiously.

  Ye Tianfan replied honestly, "Not yet, but soon. I've already got some leads and I believe that after another refinement, I'll be able to find the reason." After saying 'not yet', Ye Tianfan saw his master's face turn black, so he hastily added another sentence afterwards.

  "Alright, I'll refine it again. If the reason still can't be found out, you know the consequences." Xie Qianqiu said with an expression that you're familiar with.

  Ye Tianfan could only pray in his heart that he would really make some discoveries, otherwise it would be a disaster.

  Xie Qianqiu started to continue refining the elixir again, and Ye Tianfan also extended his divine sense into the alchemy furnace. However, this time Ye Tianfan did not observe as usual, but carefully felt whether there were any abnormalities in the five elements inside the alchemy furnace, or if there was an imbalance in the five elements.

  This observation suddenly made Ye Tianfan realize that when his master sister refined the medicinal materials into Dan liquid, almost every one of them had a slightly unbalanced place, and these were very difficult to detect with just spiritual awareness.

  Because there was only a slight imbalance, her senior sister actually succeeded in fusing these dan liquids together, but the reason for the failure also appeared here.

  Ye Tianfan discovered that in addition to the warming effect of the Dan period, there was another most important effect, which was to thoroughly merge various different medicinal liquids.

  The problem lies here, wanting to thoroughly merge the Dan liquid, but because these Dan liquids are more or less unbalanced when refined, under the situation where several or even many Dan liquids counteract each other, it instantly becomes a big problem.

  Two kinds of elixir fusions are a small problem, but the chain reaction of multiple elixirs is a big problem, which is also the reason for the explosion of the alchemy furnace.

  Found the reason, Ye Tianfan let out a sigh of relief, at least he wouldn't be scolded too badly by his senior sister.

  However, the following thing made Ye Tianfan difficult, that is how to explain himself. Should he say that according to the principle of five elements balance, he observed some deviations in the five elements balance when you were refining?

  In that case, no matter how to explain how it was discovered, it is still explaining the reason for its discovery. However, there are some things that are not easy to explain. Is it because one has a five-element spiritual root physique that they can discover it?

  If this gets out, his own senior sister will definitely treat him as a lab rat for research, and the sects of Tianqi Star will also be very interested in it.

  Soon, Ye Tianfan thought of how to say it, making his sometimes clever and sometimes foolish words convince his master sister. At this time, the furnace where Master Sister was refining medicine had exploded gloriously. However, although the furnace had exploded, Xie Qianqiu didn't rush to get angry, but instead asked: "How is it? Have you found the reason for my failed alchemy? Don't tell me you still haven't!"

  Ye Tianfan patted his chest and said, "Sister, don't worry, I've found the reason why your elixir refinement failed." "Oh? Then tell me quickly, I've been unable to refine a top-grade elixir for so long, it's driving me crazy!" Xie Qianqiu asked hastily.

  "Sister, don't be in a hurry, listen to me first. Firstly, sister, when you were refining the pill, weren't you always worried that the amount of material would be insufficient during the refinement process? So, you added a bit more, just a tiny bit. Am I right?" Ye Tianfan asked his senior sister a question.

  After nodding at his senior sister, Ye Tianfan continued: "But senior sister, your reason lies right here. You might not have thought of it?"

  "So tell me quickly, what's going on." Xie Qianqiu knew from Ye Tianfan's tone that he had really found the reason for his failed refining, so he asked hastily.

  Ye Tianfan replied, "Sister, you've added a bit of each medicine, which isn't a big deal for one or two medicines. You did the same when refining middle-grade dan medicine and succeeded, didn't you?" Xie Qianqiu eagerly asked, "Really? That's absolutely right! Hurry up and continue, why can't it be done now?"

  Ye Tianfan said, "Although you were successful in the past, Shifu, now that you're refining top-grade elixirs, not only does it require a much higher level of control over the firing process, but also strict control over the amount of medicinal materials used."

  "Now, for a top-grade elixir like this one, at least several dozen medicinal materials are needed to successfully refine it. However, the properties of these medicinal materials are vastly different, and some even have considerable conflicts with each other. If they clash, they will explode - how can that possibly succeed?" Ye Tianfan continued to explain to his master sister.

  "But why was it fine when refining the dan? Why did this situation only appear when storing the dan?" Xie Qianqiu still expressed her doubts.

  Ye Tianfan replied, "This is the most crucial part, Shifu, because when refining the elixir, apart from warming up the medicinal properties of the dan medicine, there's another effect which is to thoroughly merge the medicinal properties of various dan liquids. During this merging process, the medicinal properties of the liquids that are mutually restrictive will thoroughly erupt and explode, resulting in the blast furnace being produced."

  "It was like that, no, I still want to try again." Xie Qianqiu said excitedly. However, as soon as she finished speaking, she almost fell down, because her true yuan and divine sense were both over-consumed. Fortunately, Ye Tianfan quickly supported his own master sister.

  "Senior sister, let's wait until you've recovered from your cultivation before we refine it further. There's no rush," Ye Tianfan said. Xie Qianqiu nodded obediently, and seeing that his senior sister had agreed, he continued, "Alright then, senior sister, rest well. I'll come visit you again tomorrow." With that, Ye Tianfan left.
