After learning about the intentions of Bai Xiaowen and Li Shuyi, Xu Ling said with a smile: "the strength strengthening medicine with a purity of more than 90% is a perfect quality. Mr. Bai also pointed out that it must be above level 8, even less... As far as I know, it is not in the sales hall."


    After a pause, Xu Ling said, "Mr. Bai and miss can go to the store manager... However, he seems to be in a bad mood recently."


    "In a bad mood? Why?" Bai Xiaowen was curious.


    "I don''t know. It seems to be related to 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 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 to the pharmaceutical department behind through the internal channel of the staff.


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


    "The giant god guild is too bullying. The president must find a way to prevent them from being so arrogant."


    The old store manager Zhang Jing''s voice also sounded: "what can I do to think about it? The giant god guild is a class a guild and one of the signboards of Jinghai. Don''t mention that they opened their branch to the red fire area. Even if they opened it at the opposite door to us, what can you do? We logistics personnel, don''t try to provoke trouble for the guild. Just bear it and it will pass..."


    Sun Hecheng was still unwilling: "but our sales fell very seriously..."


    Dudududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududududui.


    Bai Xiaowen heard a few words and thought it was impolite to eavesdrop outside, so he knocked on the door.


    "Who is it?"


    The door of the office opened from the inside, revealing sun Hecheng''s national character face.


    "Uncle sun, Grandpa Zhang, it''s me."


    Li Shuyi said hello to sun Hecheng and Zhang Jing, and then pulled Bai Xiaowen in.


    When the door of the office was closed again, sun Hecheng''s gloomy face eased a lot. On Zhang Jing''s face, the wrinkles were stretched with a smile: "Hey, you''re not in college. It''s not a weekend or a holiday. How did you come here?"


    Li Shuyi said with a smile, "Xiaowen and I are from the combat department. Unlike other people''s ordinary departments, we don''t have classes casually and have no credits."


    "You can''t be lazy. You should always have classes..." Zhang Jing said.


    Bai Xiaowen and Li Shuyi listened to Zhang Jing''s nagging honestly. Then Bai Xiaowen cut off the topic: "just now I heard you talking to master Zhang. What''s wrong with the pharmacy?"


    Zhang Jing didn''t want to talk more about it. Maybe he didn''t want to distract Bai Xiaowen. He waved his hand and said with a smile, "it''s okay, it''s okay... I haven''t asked you yet. What are you doing this time?"


    Bai Xiaowen said: "I want to buy a bottle of strength strengthening medicine. The actual addition effect is about 4 o''clock. The grade should be below 8, but the purity should be high... I didn''t find it in the front hall."


    Zhang Jingxian joked: "I knew you were all right. You can''t think of me as an old man..."


    They smiled awkwardly.


    Zhang Jing touched his chin and got to the point: "the strength strengthening potions below level 1 and level 8 are basically the effect of theoretical 4 points. To achieve the actual effect of 4 points... Well, 75% purity can achieve the actual gain of 3 points. But the key last point depends on the probability. The purity should be at least 87.5%, so there is a 50% chance to increase the last point."


    Bai Xiaowen nodded and added, "the 50% chance is still a little low. I don''t know if there is perfect quality in the store?"


    Zhang Jing smiled.


    Sun Hecheng said: "it''s not easy to make perfect quality potions with purity of more than 90%. It depends on luck. Take me for example, there are 3 ~ 5 bottles of perfect quality potions every month, but most of them are low-grade. For potions above level 8, there are only one or two bottles of output a year on average."


    "How could it be so few?" Bai Xiaowen was startled. He knows the quantity of sun Hecheng''s pharmaceuticals. The output of thousands of bottles of medicine a year must be no problem. He can be called a model worker. In this way, only one thousandth of the high-grade medicine of perfect quality?


    "This involves the factors affecting the 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: "because the medicine itself contains slight impurities."


    "This is only one aspect," Sun Hecheng said. "More importantly, it is the ''proportion of active ingredients'' of medicinal materials."


    "Proportion? Before pharmacy, how many grams of each kind of medicinal material should be weighed according to the proportion formula?" Bai Xiaowen said.


    "When I say ''active ingredients'', I mean'' energy particles'' in medicinal materials! For example, the ''life particles'' contained in the silver leaf herb that makes silver light potion are active ingredients."


    "The weight of medicinal materials can be weighed in advance, but there is no way to accurately measure the effective components in medicinal materials. The life particles contained in the same amount of silver leaf grass, even if it is the same phase, must be different."


    Sun Hecheng continued: "To prepare a medicament, if you need to use two active ingredients a and B, each accounting for 50%. You use the weighing method to weigh 100 grams of class A and class B medicinal materials, which seems to account for 50% respectively, but in fact? Maybe there are a little more active ingredient particles in class a medicinal materials, accounting for 51% in the final component proportion, and only 49% of class B active ingredients."


    "Pharmacy is a process of chemical reaction. Only 49% of the total dose of class a active ingredient reacts with class B active ingredient to become medicine. What about the extra 2%? For this bottle of medicine, this 2% can only be impurities. Useless active ingredients are impurities."


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


    Zhang Jing added with a smile: "the purity is also related to the pharmacist. When the reaction of several active ingredients has just ended, the next process is carried out immediately and seamlessly, which is the most ideal state. Even if the active ingredients are not fully reacted even 0.1 seconds in advance, impurities will be produced; if the delay is 0.1 seconds, there may even be pharmaceutical failure..."


    "As like as two peas as like as two peas in the world, there are no two identical pharmaceutical processes. In the fine place, the pharmacist needs to be controlled by feeling. This is also the reason why the machine can not handle the medicinal materials and make the psychoactive agents. The rate of scrap production is too high and the cost is simply unbearable."
