Chapter 95 - 59 Penicillin_2
After finally finishing her bath, Ran Yan immediately went back to her room to grind ink and sketched down the shape of the bath tub and the appearance of the high stool. She then wrote a letter, gave it to Team Leader Yang Yong, who was guarding the manor, and asked him to send someone to deliver it to Inspector Liu immediately.
Having done all this, Ran Yan finally relaxed. After having dinner, she spent some time with Wan Lu, then went back to her bedroom to rest.
Perhaps due to exhaustion, although her sleep was filled with fragmented scenes, they never formed a coherent dream. It turned out to be the best sleep she had had in six or seven years.
In the following days, continuous rain made it inconvenient to travel. As a result, those seeking medical treatment from Ran Yan sent letters saying they didn’t dare to trouble her with a house visit and would bring the patients on the appointed date instead.
So these days, Ran Yan found herself with more free time. After seeing the patients each day, she went to see Wu Xiuhe to listen to his lectures on medicine. Ever since Ran Yan cooked that meal for him, Wu Xiuhe had clearly been even more attentive and hardworking, frequently hinting, both overtly and covertly, that she should cook a meal to reward his hard work.
Five days passed in the blink of an eye, and the penicillium in the culture solution was about ready for the extraction of penicillin.
Ran Yan poured the liquid from thirty petri dishes into a specially prepared barrel and then added vegetable oil to the barrel and mixed well.
The penicillium water contained fat-soluble substances, and oil could dissolve and separate these fat-soluble substances. After stirring evenly, she left it to settle.
