After learning about Bai Xiaowen and Li Shuyi's intentions, Xu Ling smiled and said, "The power enhancement potion with a purity of more than 90% is considered a perfect quality. Mr. Bai also specified that it must be level 8 or above, so it is even less...... As far as I know, there is no one in the sales floor. ”

After a pause, Xu Ling said, "Mr. Bai and the eldest lady can go to the store manager...... However, he doesn't seem to be in a good mood lately. ”

"Feeling bad? why?" Bai Xiaowen was curious.

"I don't know, it seems to have something to do with the pharmacy sales in the store. Although Xu Ling is the sales team leader, she is only a small cadre at the bottom.

Bai Xiaowen originally didn't want to trouble Zhang Jing and Sun Hecheng, but now there is no better way. He and Li Shuyi thanked Xu Ling, and walked through the internal passage of the staff and walked to the pharmaceutical department at the back.

Outside the office door of the old store manager Zhang Jing, Bai Xiaowen heard Sun Hecheng's voice.

"The Giant God Guild is also too bullying. The president has to think of a way not to let them be so arrogant. ”

The voice of the old store manager Zhang Jing also sounded: "What can I do to think about it? The Giant God Guild is a first-class guild, one of the signboards of Jinghai." Not to mention that they opened the branch in the Red Fire District, even at our door, what can you do? We, the logistics staff, don't think about causing trouble for the guild, just endure it and pass......"

Sun Hecheng is still a little unwilling: "But our sales have fallen very seriously......"

Tuk-tuk.

Bai Xiaowen heard a few words and felt that it was not polite to eavesdrop outside, so he knocked on the door to signal.

"Who is it?"

The door to the office opened from the inside, revealing Sun Hecheng's face in the Chinese character.

"Uncle Sun, Grandpa Zhang, it's me. ”

Li Shuyi obediently greeted Sun Hecheng and Zhang Jing, and then pulled Bai Xiaowen in.

The door to the office was closed again, and Sun Hecheng's originally gloomy face eased a lot. And Zhang Jing's face was even more wrinkled with a smile: "Hey Yoyo, aren't you in college, it's not a weekend or a holiday, why are you here." ”

Li Shuyi said with a smile: "Xiaowen and I are from the combat department, which is different from other ordinary departments, whether you go to class or not, and you don't have any credits." ”

"You can't be lazy, you always have to be ...... in class," Zhang Jingxu chattered.

Bai Xiaowen and Li Shuyi honestly listened to Zhang Jing's nagging, and then Bai Xiaowen diverted the topic: "I heard you chatting with Master Zhang just now, is there something wrong with the pharmacy?"

Zhang Jing didn't want to talk more about this matter, perhaps because he didn't want to distract Bai Xiaowen and the others, so he waved his hand and smiled: "It's okay, it's okay...... I haven't asked you yet, what are you doing here?"

Bai Xiaowen said: "I want to buy a bottle of strength-type enhancement elixir, the kind with an actual bonus effect of about 4 points, the grade should be below level 8, but the purity should be high...... Didn't find it in the antechamber. ”

Zhang Jing made a joke first: "I knew that you were fine, it was impossible for you to think of me, an old man......"

The two of them smiled awkwardly.

Zhang Jing touched his chin and got to the point: "The strength enhancement potions below level 1 and level 8 are basically the effects of the theoretical 4 points. To achieve the practical effect of 4 points...... Well, 75% purity can achieve an actual gain of 3 points. But the last point of the key is to look at the probability, the purity must be at least 87.5%, there is a 50% chance of increasing the last point. ”

Bai Xiaowen nodded and added: "The 50% chance is still a bit low. I wonder if there's a perfect quality in the store?"

Zhang Jing smiled.

Sun Hecheng on the side said: "A perfect quality potion with a purity of more than 90% is not so easy to make, it depends on luck. Take me as an example, on average, there will be 3~5 bottles of perfect quality potions every month, but most of them are low-level. For example, the average annual output of potions above grade 8 is only one or two bottles. ”

"How can it be so little?" Bai Xiaowen was taken aback. He knew the number of medicines in Sun Hecheng, and the output of thousands of bottles of medicine a year must be no problem, which can be called a model worker. In this way, the proportion of perfect quality high-grade elixirs is only one thousandth?

"This involves factors that affect purity," Sun Hecheng explained, "Xiaobai, do you know why the purity of the medicine is high and low, and it is almost impossible to reach 100%?"

Bai Xiaowen hesitated for a moment: "It's because the medicinal herb itself contains slight impurities. ”

"This is only one aspect," Sun Hecheng said, "and more importantly, the 'active ingredient ratio' of the herbs." ”

"Proportion: Before making a medicine, how many grams of each medicinal material is needed, isn't it all weighed in advance according to the proportional formula?" Bai Xiaowen said.

"When I say 'active ingredient', I mean the 'energy particles' in medicinal herbs! For example, the 'life particles' contained in the Silver Leaf Grass, which makes the Silver Light Potion, are the active ingredients. ”

"The weight of medicinal materials can be weighed in advance, but there is no way to accurately measure the active ingredients in medicinal materials. The same amount of Silver Leaf Grass, even if it is of the same condition, the life particles contained in it must be different. ”

Sun Hecheng continued: "To prepare a drug, if you want to use two active ingredients, A and B, each accounts for 50%. You use the method of weighing to weigh 100 grams of Class A and Class B medicinal materials, which seem to account for 50% each, but in fact, it may be that Class A medicinal materials contain a little more active ingredient particles, accounting for 51% of the final ingredient ratio, and only 49% of the active ingredient of Class B. ”

"Pharmaceuticals are the process of chemical reactions, and only 49% of the total dose of Class A active ingredients will react with Class B active ingredients to become pharmaceuticals. And what about the extra 2%? For this bottle of potion, this 2% can only be impurities. If there is no active ingredient, it is impurity. ”

Sun Hecheng concluded: "The above is the simplest example, the actual prescription will only be more complicated, and the more advanced the fortifying potion, the more types of medicinal materials will be required for the formula, and the proportion of active ingredients will be more difficult to grasp." The first type is more than 1%, the second type is more than 2%, and the third type is less than 3%, and the total amount of impurities accumulated is terrible. ”

Zhang Jing added with a smile: "Purity is also related to the pharmacist. At the end of the reaction of several active ingredients, the next process is immediately carried out, and the seamless connection is the ideal state. Even if the active ingredient is not fully reacted by even 0.1 seconds, impurities will be generated, and if the delay is 0.1 second, there is even a possibility of pharmaceutical failure......"

"No two leaves are the same, and no pharmaceutical process is the same twice. In the subtleties, the pharmacist needs to control it with feelings. This is also the reason why it is not possible to process medicinal herbs and make psionic potions by machines, and the scrap rate of mechanized production is too high to bear. ”
