Grandma's bear actually cut half of his fingernails by chopping vegetables, and the speed of code words is simply slower than that of a snail, and blind typing can't go on, alas!

"Mentor!" Cook took Lei to Lyle's room early the next morning, and Lyle was already here, Cook didn't know if Mentor Lyle didn't go back, or Mentor Lyle was waiting here early in the morning.

"Hehe, Cook, you're here, you must already know the situation of yesterday's auction, the points will be given to you as much as possible, and Zagot will give it to you directly when the time comes." Lyle looked at Cook with a smile.

"So, Mentor, what am I going to do today?" asked Cook, asking.

Lyle pondered for a moment, then turned around and took out a book from the bookshelf next to him and handed it to Cook: "Here are some of my refining experiences and notes, it is the most basic knowledge of pharmacy, this is a magic book, I hope you can master the types in this book as much as possible, as for what potions you want to refine, it's up to you, I have already instructed Zagot, you can use the materials in the three warehouses B, C, and D in the warehouse." ”

Lyle thought about it all night last night, and finally decided not to be busy letting Cook refine the potion first, firstly, the price will definitely drop if there are more potions, and scarce things are expensive! Second, Lyle does not want to delay Cook's talent, although Lyle also wants Cook to keep refining, but Cook's own level cannot be improved, so it is not good for Lyle, and Lyle, as a mentor, is most responsible for cultivating a strong pharmacist for the union.

Cook was stunned, originally Cook thought that the assistant was to be a coolie, Cook was ready to refine the secondary stealth potion every day, Cook asked suspiciously: "Mentor, don't refine the potion today?"

"Hehe, if you don't refine it, you don't think you have to refine a secondary invisibility potion, do you?" asked Lyle with a smile.

"The price is so high, why don't you refine it?" asked Cook, confused.

Lyle looked at Cook, then stood up and said, "Cook, the rarer things are, the more valuable they are, and once everything is more, then it is not worth much, we are noble alchemists, not those coolies." ”

"Mentor, I see. Cook was stunned, these people still knew the starving sales model. Then he nodded.

"Well, your daughter is lovely. Lyle looked at Xiao Lei, who was looking at him with big eyes, and exclaimed.

Cook sweated profusely, knowing that he had lost tens of thousands of gold coins for the things in the dormitory, which was cute, but Cook then asked weakly: "Mentor, I want to exchange points for magic cores, I don't know if it's okay?"

"Yes, in exchange for something else's magic core?" Lyle asked casually, not at all surprised.

"Thunder or fire will do. Cook said hurriedly.

"Well, I'll ask Zagott when I go back, Rayder can't guarantee that there are a lot of them in the fire-type warehouse. Lyle nodded.

Cook saw that Lyle began to sit down again, so he retreated, and then picked up the note that Lyle handed to him and sat in front of the test bench to look, this time Cook realized that this was actually a magic book, the magic book is to be viewed with mental power, the advantage is that it is easy to remember, but the writing of the magic book is only a little better than the magic scroll.

Cook let go of his mental power, and the first thing he saw was, quality determines a qiē!

Then Cook read it carefully, but in half an hour, Cook finished reading, to be precise, this is a record of fifteen recipes, as well as Lyle's experience in refining potions, but they are all low-level potions.

Cook put down the spellbook, then closed his eyes, and thought about it, Cook didn't think that the recipe that Mentor Lyle wrote in the spellbook would be an ordinary formula, and Cook finally knew the key to how to improve the quality of the potion.

Improving the quality of the medicine is not only to grasp the timing of refining, but also the purity of the material is also very critical, the higher the purity of the material, the higher the quality of the refining agent, and the purification of the material can be divided into several aspects, one is high-temperature purification, and the other is low-temperature purification.

High-temperature purification without exception is to bake with fire, then grind the ingredients, and finally purify with water, this high-temperature purification is suitable for most materials, but some materials are not suitable for high temperature at all, so low-temperature purification has been invented again.

The low temperature is mainly soaked in water directly, and then constantly stirred, but also pay attention to the temperature, and then filter and blow the wind to evaporate the water, and finally get a material with high purity.

There is also a hit purification method that makes Cook can't help but take a breath of cool air, it is said that some precious materials will be directly purified with magic power, spiritual power, or magic array, of course, this has a high limit on the level of the person who purifies.

Cook looked at Xiao Lei, this little guy actually fell asleep on the side, to be honest, there is a cradle next to the test bench It is estimated that Cook is still the first person.

Cook stood up, found out the materials needed for the secondary invisibility potion, and then carefully observed it with the magic eye, this observation Cook found that the luster of these magic materials was not the same, there were some other spots, and many of these materials were like traditional Chinese medicine, or the rhizomes of plants, just like the green spotted fruit was a fruit, and it was not purified at all.

Cook began to purify the material, and Mentor Lyle smiled bitterly on the side, because the success rate of the secondary invisibility potion was too low, and if it was purified again, the cost would be even more high, but Lyle did not stop it, but carefully observed.

Cook prepared the tools for purifying the material, flasks, beakers, test tubes, strainers, knives, and grinding utensils.

Cook crushed the green spotted fruit directly into small particles, and then put it into the beaker, heated it slowly, and slowly stirred the beaker, and Cook's magic eye carefully observed the aqueous solution, half an hour, Cook found that the aqueous solution finally changed color, becoming the same color as the green spotted fruit, and the green spotted fruit particles had no luster, and the water in the beaker was only half of the original, Cook quickly took the beaker down, and then filtered out the solution with a filter, so three times, the solution finally had no impurities, and Cook used the flask to heat the solution directly。

"Just a little bit?" Eventually, Cook retrieved a pinch of powder from the bottom of the beaker, but the powder was several times the color of the green spotted fruit, and Cook carefully collected the powder, and then began to clean the beaker and flask.

"Looks like you need a helper!" Lyle said with a smile as he looked at Cook, who was busy with greenery.

"Uhhh

"Do you need me to find a helper for you?" Lyle gestured to the utensils in the sink.

"Mentor, thank you for your concern, I will bring a helper in the future. "Cook doesn't want anyone to know his secret, if nothing else, the less people know about Xiaolei's weirdness, the better.

"Yes, you have preliminarily mastered the purification of materials, but it should be noted that the proportion of materials after purification is the same, but you have to master this base number well, and some of the materials will be lost in the process of purification, so you should prepare more materials before purification. Lyle carefully used his mental power to distinguish it, and found that the material purified by Cook was very good.

"Thank you for your teachings. Cook hurriedly thanked him.

"So are you ready to refine it now?" Lyle asked, pointing to the purified material, Lyle was very eager to see what kind of quality potion Cook would refine this time.

"Yes, Mentor!" Cook looked at the time, and before he knew it, five hours had passed.

"Hehe, the purified material reacts very quickly, you have to pay attention. Lyle reminded with a smile.

Cook didn't care about this sentence at all, and when Cook put in the two purified materials, Cook didn't even have time to get the third material, and the potion in the flask was already scrapped.

Cook looked incredulous, and after Lyle casually closed the magic furnace, he patted Cook on the shoulder and said, "You shouldn't have finished reading my experience, it is best to use the low-temperature refining method to use the purified materials, which will slow down the speed of the reaction." ”
