For the first taste, there was no problem with the Qing Filthy Grass, and there was a light green and transparent liquid floating above the Dan Furnace.

In the second taste, there was no problem with the blood refining grass, and there was an extra cloud of light red and transparent medicinal liquid over the Dan furnace.

However, no one expected that when they only reached the third step and refined the bitter grass, a strange force suddenly shook in the entire Dan furnace, and a cyan color was born, and the flames in the entire Dan furnace skyrocketed.

Xiao Mo couldn't react at all, and in an instant, the three balls of Dan liquid he had worked so hard to refine in the entire Dan furnace turned into flying ashes at the same time.

"How...... Possibly?"

Xiao Mo stayed where he was for a while.

He was sure that he had been careful enough to refine this time, and there were no problems. If last time he only failed in alchemy because of mental fluctuations, then this time, what is the reason?

And last time, Xiao Mo only had a problem when he was full of the main materials, but this time, he didn't even pass the level of refining the auxiliary materials, which was a bit beyond his cognition.

It's not terrible to have a problem, if you find a problem and solve it, you won't do it again next time, but this time, Xiao Mo was stunned, because he didn't know what the reason for the refining failure was.

"What, can't figure it out?"

Seeing this, Zhongli Danshi smiled slightly, looked at Xiao Mo and said.

Xiao Mo nodded and said, "Yes, Master Zhong, I am sure that there is no problem with my refining technique, mind control, and even the temperature of the flame, but why, this time it will still fail, and it will fail in the most basic auxiliary material refining?"

Hearing this, Zhongli Danshi nodded, and said, "If you can only think of these three points, then it's normal that you can't figure it out." Alchemy is a very complicated matter, and it is not only about refining techniques, mind control, and flame temperature, what a truly skilled alchemist has to consider is far more comprehensive and complex than this!"

Xiao Mo knew that Zhongli Danshi was taking the opportunity to raise himself, so he was not in a hurry to start doing it again. Before discovering the problem that led to the failure, no matter how many furnaces he took over and refined, the result would be the same, so he must first find out the reason for his failure.

After solving the reason, you can start refining the next furnace of Dan.

"Please advise Master Zhong!"

So this time, he said sincerely, respectfully.

Zhongli Danshi was about to speak, when suddenly his eyes turned and fell on the girl in Tsing Yi who had been standing next to him, silent, and suddenly said, "Xiaotong, this time, it's up to you to point out your junior brother's shortcomings!"

"Yes. ”

Hearing Zhongli Danshi's voice, Zuo Xiutong, a girl in Tsing Yi, stepped forward and said to Xiao Mo with an expressionless face: "When refining a furnace of Dan, you must not only consider the alchemy technique, mind control, flame temperature, the most basic and the most easily ignored, is your mastery of medicinal properties. ”

Speaking of this, she paused for a moment before she said again: "Different medicinal materials have different growth environments, and even the same medicinal materials may grow in various places with different attributes, and the different growth environments also determine their different medicinal properties. ”

"For example, the gray level low-level spirit grass red fire grass generally grows in volcanic lava caves or places with high temperatures, but some cold and damp places can also grow, it does not mean that there is a problem with this red fire grass, but that kind of place, it is very likely that there is a rich attribute fire mine underground. ”

"Therefore, as long as there are fire elements that are in line with the growth of red fire grass, red fire grass may grow, and the red fire grass produced in these three places has a slight difference in medicinal properties. ”

"The red fire grass that lives on the volcano only has pure fire attributes, and the fire attribute is very fierce and the medicinal properties are extremely strong; the red fire grass that grows in the underground molten cave is still a fire attribute, but it will also carry a trace of water attribute; and the red fire grass that grows on the earth fire mineral deposits will have a trace of metallicity in addition to the fire attribute. ”

"When refining pills, in addition to what you mentioned above, the distinction of the properties of various herbs and pharmacology is something that should be mastered and considered before you really start alchemy, so the teacher will teach you to memorize the psychic medicine at the beginning, ordinary people generally study for a year and a half before starting formal alchemy, and you want to open the furnace for alchemy after only a month, it is really rare, the foundation is not solid, and it will be empty after all. ”

When Xiao Mo heard this, he finally couldn't help but suddenly realize, and even couldn't help but feel a trace of shame on his face.

Although what the girl in Tsing Yi said was not polite at all, it pointed out Xiao Mo's problem to the point, that is, he ignored the mastery of pharmacology and medicinal properties, and there is no doubt that this should be the most basic basic skill of every alchemist.

As the girl in Tsing Yi said, if you don't even understand the pharmacology of medicinal properties and blindly alchemy, you can only end up with a bamboo basket and empty water, and your efforts will be in vain.

Therefore, even though he knew that the girl in Tsing Yi was accusing him of being so ambitious, Xiao Mo could only accept it with an open mind, not only was he not angry, but he was full of gratitude.

Only then did he remember that before the earliest, Zhongli Danshi did not teach him alchemy, but was directing him to make various choices, screen, and then carry medicinal materials to him.

It was in the process of selecting, screening, and transporting medicinal materials that he had the opportunity to directly contact a large number of medicinal materials, and had the opportunity to distinguish the names and years of medicinal materials, and even the only time to distinguish the medicinal properties.

If you can't see these things at this time, all the next preparations will be in vain.

However, it was obvious that at that time, the medicinal materials he submitted only had names at most, and there was no problem with the age, but the medicinal properties were not taken into account, and Zhongli Danshi did not remind him, but used other ingenious methods to resolve them.

Xiao Mo didn't find a problem from beginning to end, until now, Zhongli Danshi used those negligences to leave Xiao Mo with a failure.

And this failure is the best teaching of Zhongli Danshi, only if he has fallen down himself, he knows the importance of seeing the road when walking, and he does not know the lesson.

Many stories tell us that people who tripped over a branch were definitely much less likely to trip over the same branch a second time than someone who hadn't seen it before.

Xiao Mo thought carefully about how he felt when he handled the second four-flavor medicinal herb before, and suddenly his heart suddenly moved, and he remembered.

There is no problem with the other three flavors of medicinal herbs, but the bitter grass, at that time, Xiao Mo found that under its roots, there was a little bit of pale golden fragments, Xiao Mo didn't care at that time, and directly removed it as mud, and now I remembered that the bitter grass should have grown on a piece of metal mineral.

The bitter grassland is warm in nature, and the color is black, but it is contaminated with metal minerals, and its properties contain a little metallicness, gold and water...... Water overcomes fire......

It is very normal to use the normal temperature to melt the bitter grass, and the result is a direct failure.

The answer was finally found, and Xiao Mo finally couldn't help but breathe a sigh of relief, however, to find out the problem, the next step is to solve the problem.

This time it was a failure, and the bitter grass with metallic properties did not exist, but next time, if I encountered the same problem again, or encountered other problems that were different but similar, how to solve them?

Zhongli Danshi looked at him with a smile, and did not open his mouth to point, but let Xiao Mo stand there and think.

After a while, Xiao Mo's eyes lit up, and he said with great joy: "I know, gold gives birth to water, water overcomes fire, and fire in turn overcomes gold, so there will be problems, and it is very simple to deal with this bitter grass, as long as I soak it in red spirit water for half a moment before refining this herb to dissolve the metallicity in it, then there will be no more problems with refining." ”

When Zhongli Danshi heard this, he smiled and nodded, and said, "The children can be taught." However, yours is still only the most basic method. ”

"Well, what better way?"

Xiao Mo raised his head and asked suspiciously.

Zhongli Danshi said: "You are a headache doctor, and you are a doctor with foot pain, and ordinary quack doctors will do this, but a clever doctor can see the essence of the real headache from the headache, and the cause of the foot pain can be seen in the same way, in the alchemy, if a medicinal herb contains metallicness, then, in fact, when you choose a medicinal herb, you just need to choose a plant that contains the same fire attribute to neutralize it." ”

"Huo Kejin, two by two, and refining at the same time, in this way, a temporary processing process is saved, one less alchemy step is missing, and the materials that need to be used are also saved, what do you think?"

"Well, I see!"

When Xiao Mo heard this, he couldn't help but suddenly realize, but then he said: "But refining two strains at the same time, won't the difficulty increase?" Two medicinal materials with different medicinal properties are put together, some enhance each other, some clash with each other, and at the same time, the melting temperature of the medicinal materials will also be different, which is more than twice the difficulty of an alchemist's need to be tested and refined. ”

Hearing this, Zhongli Dan Master nodded and said, "Yes, what you said makes sense, but we alchemists, if we can't even do this little requirement, how can we talk about hitting a higher bottleneck?" Although the blind refining is stable, but the speed is too slow, and the consumption is too huge, the early stage is fine, the later refining of the pill, the medicinal materials that may need to be used are dozens or hundreds, you refine them one by one, the difficulty will be greater, the time is too long, the alchemist will be more unbearable, so only by mastering the ability to multitask, you can refine several kinds together, or even dozens of medicinal materials, in order to go further and further, so instead of waiting to learn later, it is better to master it from the very beginning, so that when you learn in the future, it will be simpler and not so difficult。 ”

"Yes, the disciple has been taught. ”

Hearing this, Xiao Mo nodded, and finally decided to follow the method taught by Zhongli Danshi.

Indeed, now refining a pinpindan, there are as many as four kinds of medicinal materials that need to be used, and this is only the simplest pinpindan, if it is a little more complicated, a higher grade of yipindan, some of the medicinal materials involved are also seven or eight, or even nearly ten.

At this time, blindly refining, not only wasting time, but also consuming energy, after a long time, mental fatigue, all kinds of uncontrollable risks will increase significantly, so mastering the ability of synchronous refining is a necessary means for every alchemist.

At the level of Zhongli Danshi, refining a pill may involve dozens, or even hundreds, of medicinal materials, and the ingredients of various medicines are more complex, and the shengke between each other will be more obvious, if you don't practice from now, you just want to use that kind of safe way to refine the pill, and you will be desperate in the later stage.

It's just that practice is okay, but when Xiao Mo hasn't even refined the pill once, he naturally has to come blindly, the first thing he has to do is to succeed once, and only after success, then consider other ways to practice.

Therefore, Xiao Mo calmed down his mood and made sure that he had reached the realm of stopping water in his heart, so he stepped forward again and came to the alchemy furnace, but he did not immediately open the furnace for the third alchemy, but first checked the four flavor medicinal materials.
