There are two shifts today, and there will be one shift later!

"Let's take a good look!" Lyle said with a smile after seeing Cook's embarrassed look, patting Cook on the shoulder and turning away.

Cook looked at the back of Lyle leaving, and then looked at Xiao Lei, who was still sleeping, took a deep breath, and then picked up the magic book again and looked at it carefully.

If you want to reduce the reaction speed, the method is very simple, that is, reduce the temperature, after the temperature is lowered, the speed of the reaction will slow down, but the higher the purity of the material, the higher the failure rate, because the high purity of the reaction time is more difficult to master, the purity of the material is low, and the reaction time is slow, so this time is easier to master, and the cost of purification of this material is too high, just like Cook spent five hours to purify the material of a secondary invisible potion, if it is refined, at least three bottles have been refined.

This is also one of the reasons why many pharmacists are reluctant to purify materials, after all, the success rate is based on the accumulation of bases, although the purity of the material is improved, the probability of high-quality agents will be greater, but this probability is not easy to say.

Cook put down the magic book in his hand, and then began to purify the materials again, this time Cook had the experience of purifying for the first time, and it took half an hour to purify the two materials that had just been used, Cook looked at the tools in the cleaning pool, couldn't help shaking his head, and muttered to himself in his heart: "It seems that I really need an assistant." ”

Cook put the flask on the magic furnace again, the magic furnace is actually a magic crystal as an energy source, and then the magic array emits a high temperature and high heat, not those furnaces that burn directly, and the temperature of the magic furnace can be controlled, it is achieved by absorbing the energy in the magic crystal through the magic array, Cook adjusted the temperature of the magic furnace to a very low level, basically only a feeling of warmth.

Cook then put all the purified materials in order of addition, and then began to refine, Cook now only has two potions, one is an antidote, and the other is a secondary invisible potion, both of which are low-level magic potions, but the difficulty of refining is much different. The difficulty of refining the antidote is C-level, and the secondary stealth potion is S-level, and the difficulty of refining is a total of nine levels, from difficulty to ease, they are SSS level, SS level, S level, A level, B level, C level, D level, E level, and F level.

Cook's right hand put on a glove, which is also a magic item, the main thing is to isolate the temperature, and then held the flask hard, the matrix liquid in the flask was already slightly hot, Cook picked up the first potion to be added with his left hand, Cook's right hand shook the gas flask, Cook's magic eye found that the purified materials reacted to each other very quickly, and if the materials were not purified, it was estimated that it would take a few minutes, but it was only a few seconds, and the color of the potion under the magic eye had reached the color of the suspicious addition of the second material。

Cook's left hand moved, and the second material that had been prepared was put in instantly, and then Cook quickly picked up the third material and prepared it, due to the extremely fast reaction, Cook had to speed up the speed of shaking the flask, his nerves were tense, and the third material was put down instantly, the fourth, fifth, Cook added almost at the rate of ten seconds of one material, and some of them were simply one or two seconds.

"Bang!" Cook finally finished refining, and as soon as Cook's nerves relaxed, the crystal bottle containing the materials in his hand suddenly fell to the ground and turned into a pile of crystal fragments.

Cook only found out at this time that he was soaked, the constant temperature of the robe did not play any role at all, obviously this is not hot, but Cook is sweating nervously, Cook still used the filter to filter the potion again, Cook found that this time the potion is not gray at all in the naked eye, but a slightly flooded transparent color, and under the gaze of the magic eye, it is bubbling with golden light, Cook is a little confused, this golden light is the surface of the golden magic element.

Cook had a headache, so he had to take the refined potion to Mentor Lyle: "Mentor! ”

"Already refined?" Lyle almost didn't believe Cook's words, because the refining of the purified materials, even Lyle himself could not control it well, because the reaction speed was too fast, too fast, even if the refining of the potion was a second, two seconds could lead the medicine to fail, and Lyle only dared to use the low-grade potion to make a real, even so, Lyle used the purified material to refine the low-grade elixir, and the refining difficulty was above the D level The elixir has not been successful at all, and that's it, it is only a bottle of high-grade elixir, really, it is too difficult to improve the quality of the elixir, too difficult, the difficulty of refining, the purity of the material, and the refining technology have greatly restricted the quality of the elixirAs long as one link goes wrong, then the quality of the medicine cannot be improved.

Take the purification material as an example, how to master the purity, how to the highest purity, if it is not good, it is very likely that the material will be scrapped in the purification, so it is difficult to improve the quality of the drug.

However, when Lyle saw the potion handed over by Cook, his hands trembled, because Lyle had seen such a potion more than a hundred years ago, and Lyle almost snatched the potion from Cook's hand, and then dropped a drop with a straw and put it into a container instrument.

"Perfect quality!" Although Lyle can be sure with the naked eye that this is a perfect potion, because more than a hundred years ago, there was such a bottle of perfect level healing potion at the auction, and the difficulty of refining the healing potion was E-level, even so, it was finally sold at a sky-high price, and it was said that it was purchased and studied by the Pharmacist's Guild, in fact, it is accurate to say that the pharmacist is an association under the Magician's Guild, but people outside call it the Apothecary's Guild.

"Perfect quality!" Cook was also stunned, Cook didn't expect that the potion he had refined this time was actually the highest quality.

"Cook, how did you do that?" asked Lyle, excitedly grabbing Cook's hand.

"I don't know, just follow the program!" Of course, Cook wouldn't say that he could see the reaction of the potion, and it would definitely be more accurate to see with the magic eye than to perceive it with mental power.

"Cook, I have a request, I hope you can sell this potion to me, or exchange it for me, this is the second bottle of perfect potion I've ever seen, I hope I can collect it. Lyle tightly grabbed the potion in his hand and said excitedly.

Cook still couldn't accept Lyle's way of talking, but Cook thought for a moment and said, "Okay, but I hope to get a high-quality Thunder Core." ”

"No problem! Isn't it the magic core? What other requirements are there?" In Lyle's opinion, the perfect quality potion is simply the favor of the goddess of luck, even if it is Cook, it is impossible to refine a second bottle, if Lyle knows that Cook will refine a bottle of perfect quality potion in ten days on average, this is still Cook did it on purpose, I don't know if Lyle will be so excited.

"Mentor, I want to ask, what is a soul crystal?" Cook thought that Big Mouth had been in a coma after eating soul crystals for the past few days, so Cook was going to ask.

"Soul crystals, are you sure you're not wrong, where did you know the word soul crystals?" asked Lyle, his eyes wide.

Cook felt a sigh in his heart, knowing that the soul crystal must not be a simple thing, so he smiled and said, "I heard it from others. ”

"Hehe, soul crystal, soul crystal can be said to be one of the most precious materials, soul crystal, soul crystal, is soul crystal, but to soul crystal, at least the soul of a demon beast or professional above level eight has to be extracted, and then purified with a magic array, the most inferior soul crystal is also worth millions of crystal coins, not gold of gold, but the crystal of magic crystal. Lyle said with a smile.

Cook was stunned by this sentence, because in the bag given by Uncle Ernie, there were seven or eight soul crystals that Ernie said, Cook subconsciously thought that it was not a soul crystal, but Cook didn't dare to take it out for Mentor Lyle to identify, because millions of crystal coins, this is an astronomical amount, but then Cook became even more nervous, because if it was really a soul crystal, then wouldn't it be difficult for Ernie to help himself, very difficult.

"Mentor, I'm leaving, I'll come back tomorrow when I'm hungry. Cook thought of the risky action that required nearly 10 million soul crystals as a deposit, Cook realized the crisis, and Cook didn't dare to run, Cook dared to guarantee that the characters who could take out nearly 10 million soul crystals casually were probably not something anyone could provoke.

When Lyle heard Cook say this, he wished that Cook would leave early, because Lyle couldn't wait to see the refining process of Cook, which was recorded by the magic image, and Lyle smiled and said, "Okay, the magic core will be sent to you." ”

Cook walked out of the real area with Xiao Lei, who was still asleep, and Cook was upset, because Erney's so-called adventure must be full of danger, but then Cook took a deep breath, and then as if he had made up his mind, he quickly went to the general hall.

Cook made up his mind while looking at the taskbar in the comprehensive area: "The best way now is to improve your strength, how much can you improve in the shortest possible time, you can't just cultivate, you still need to fight, keep fighting!" So Cook came to the task release place of the comprehensive area to take a look.
