Lu Qiming took this plain white jade vial, and carried a few traces of moisturizing in the cold, which was obviously not an ordinary jade. Special materials should be added to it to refine together, but what this extra thing is, just by this glance, Lu Qiming is not sure.

He turned the bottle again, and saw a plum blossom carved shallow on the side, with a few brushstrokes and a godly appearance. Lu Qiming's heart moved, and he remembered a name.

Plum Blossom Hall.

There are the most outstanding people in the world in the plum blossom hall, but they always regard themselves as merchants. From ordinary storage utensils in Lu Qiming's hands to peerless magic weapons that resonate with heaven and earth, everything is sold, and the prices are clearly marked at a glance. Everyone has heard the description of "priceless treasure" - and sometimes it is true - but here in the Plum Blossom Hall, there is no such thing!

But it's because they are too serious about buying and selling, but they make anyone with a discerning eye taste of "game world".

However, even if this white jade vial is indeed only used to contain medicines, as long as it comes from the Plum Blossom Palace, it must be extraordinary, rare, and valuable.

Lu Qiming couldn't help but be aroused. What is the medicine in this bottle that is worthy of the master to use the bottle of the Plum Blossom Palace?

Zhang Dayan was also holding an identical bottle at this time, he blinked, and said mysteriously: "This is my masterpiece!" As he spoke, he pulled out the cap of the bottle and said boldly: "Come on!

However, Lu Qiming watched him drink for a long, long time.

Lu Qiming shook the bottle and said suspiciously, "Master, is there a small space in this bottle?"

There are some special-purpose bottles and cans that are specially added to a small space like a storage vessel when refining, so that the amount that can be filled is much larger than the appearance. For example, Lu Qiming heard Xie Yundu say that his purple jade wine jug didn't look big, but in fact, it was full of wine from five directions, and it was divided into three different varieties.

Zhang Dayan finally finished drinking it for a while, shook his head and said, "No, it's just a little thick." ”

As soon as he spoke, the air immediately filled the air with the smell of black sesame paste.

Lu Qiming's expression became strange, and he said slowly: "Master, what are you pretending to be?"

Zhang Dayan tried hard to ask him with a straight face: "What do you smell like?" Before Lu Qiming could answer, he couldn't help but smile at first, and said proudly: "It's like black sesame paste!

Lu Qiming looked down at the elegant jade vase carved with plum blossoms in his hand, and deeply felt the elusiveness of his master's way of thinking.

Zhang Dayan suddenly showed a tricky smile again: "Didn't you say that the refining of potions is very simple that day, no matter which one it is, you can distinguish the formula as soon as you smell it—what about this time?"

Lu Qiming was stunned, and finally remembered that he seemed to have said this...... It was the time of the grotto on the wall to argue with them. But at that time, the three of them were arguing so fast that what they said didn't go through their brains, and Zhang Dayan actually remembered it......

Zhang Dayan haha: "Don't say it smells this time, I promise you won't be able to tell if you drink it!"

Although this agitation was obvious, Lu Qiming still opened the cap.

Zhang Dayan frowned vaguely when he saw him take the first sip, gloating: "Don't like it? ”

Lu Qiming sighed, trying to ignore the strange taste, and focused on the distinction between the ingredients and effects of the potion.

Zhang Dayan quickly took out a pen and paper and handed it to him.

......

Extremely complex process.

Lu Qiming was the first to be sure of this, which made him feel a little relieved - at least it showed that Master was serious about refining, not playing around with a jar of black sesame paste.

Secondly, the taste is accidental.

Lu Qiming's first rough feeling knew that there were nearly three hundred different main spiritual materials, and there were countless auxiliary materials. This is obviously a precise, iteratively calculated ratio. It would be an exaggeration to take into account such a secondary thing as taste.

But I had to admit that the strong smell of black sesame paste brought great interference to Lu Qiming, especially when there were a large number of such spiritual materials.

Then start with the role and work backwards. Lu Qiming thought.

It is full of spiritual power, but it is not absorbed by the body and is free from the outside...... No, it should be said that it is a simulation of internal forces? It is also related to the knowledge of the sea?

Speculations are quickly generated and constantly overturned by new ideas. Lu Qiming quickly wrote and drew on the paper.

Zhang Dayan came over, and when he saw that he really used the Dan Dao method, he didn't care, his expression was leisurely, and his smile became deeper and deeper.

Lu Qiming quickly filled nearly a page, and his pen speed slowed down until he stopped completely. Zhang Dayan took a moment to fold his arms and said with satisfaction: "I don't know what to do after that, don't you?"

"It's all wrong. ”

Lu Qiming helped him continue this sentence, and with a touch of his fingertips, he scattered the paper that had not yet dried into powder.

He looked up at Zhang Dayan and said with a smile, "Master, you seem to have forgotten to tell me a word before. ”

Zhang Dayan was a little weak-hearted, but he still didn't believe that he could think of it, so he asked stiffly, "What?"

"This potion is a semi-finished product. Lu Qiming smiled and added: "To be exact, it is half of the finished product." ”

With that, he raised his hand and flattened a new piece of paper and began to write again.

Zhang Dayan was stunned for a moment, swallowed the sentence "That's right, you win", and instead raised the standard and said: "Write the name of the two percent of the medicinal materials correctly, even if you win." ”

Lu Qiming smiled and did not speak.

The speed of the practitioner is also reflected in the writing. Even if the types of spiritual materials used by Zhang Dayan were extremely large, the "two percent" still passed in the blink of an eye.

Zhang Dayan put away his smile.

Soon - 30 percent, 4 percent, 50 percent...... Lu Qiming never paused at all when he put pen to paper!

Zhang Dayan's expression has changed to solemnity. The potion came from him, and he was the one who knew the difficulty best. But Lu Qiming ......

After writing the main material, Lu Qiming paused for a moment and explained: "I can estimate the scope of the following materials, but there is more than one feasible one, so I wrote it in overlapping columns." ”

"Wait!" Zhang Dayan waved his hands back and forth, and shouted again and again: "Good apprentice, you don't have to write, I believe it, I believe it!

Lu Qiming stopped writing like a stream.

Zhang Dayan was puzzled: "You ...... What a taste?!"

"How is that possible. Lu Qiming smiled and said, "Part of it is through the perception of spiritual power, and most of it is calculated. ”

"Extrapolation?!" Zhang Dayan was even more puzzled.

Lu Qiming nodded, and then said, "But that's the end of it." Master, the traditional ...... you use Well, orthodox alchemy, so I can't confirm the auxiliary materials. And Master, your branch is too complicated, and I can't figure out the steps at all......"

"You're still going to calculate the steps?!" Zhang Dayan jumped up. But after thinking about it, even he can push himself to such a point with such a big difficulty, and change it to a simple one, wouldn't it really be possible?!

Zhang Dayan did ask. Lu Qiming replied: "I have only tried four grades and below, and I need to feel the effect of the medicine myself to calculate." ”

After a long period of shock, Zhang Dayan's expression suddenly wandered.

Lu Qiming was a little hairy by him, and asked tentatively, "Master, what do you think of again?"

Zhang Dayan said with longing in his eyes: "Good apprentice, for the teacher, I will take you to the ancient land of Poria and Yuelu Academy to taste their treasure potions-hahaha, then wouldn't it be easy for us to know their treasure formula?!

Lu Qiming couldn't cry or laugh.
