Just as Chen Yi was stunned, the door in Sun Simiao's house opened, and the old Taoist's face, which was no different from the previous few days, appeared in front of him.

Chen Yi quickly stepped forward to salute: "I have seen Taoist Master Sun! I haven't seen Taoist Master for so long. I missed this period of time. I originally wanted to come and see the Taoist Master earlier, but I just returned from Jiucheng Palace. After I came back, I had a lot of things to deal with. I wasted time. I came too late. Please forgive me!" Chen Ming and Chen Liang also followed him to salute.

Sun Simiao stroked his gray beard and smiled and said, "You are polite. I know you have a lot of things to be busy now. It is rare to take time out of your busy schedule to visit me and Qing'er!" He looked at Ning Qing again and ordered, "Qing'er, you and his two companions have not had lunch yet. You can prepare it. It will be delivered to the teacher's house later. The teacher and Ziying talked with a thirsty wine!"

"Yes, Master!" Ning Qing responded, bowed and prepared to quit, but hesitated, and even looked at Chen Yi secretly.

Sun Simiao saw it and asked Chen Yi without saying a word, "Ziying, you come to Zhongnan Mountain today, so you shouldn't be in a hurry to rush back so early. Let Qing'er clean up the room for your master and servant. You still live in that room before, and your two entourages will stay in the guest room!"

"Thank you for the arrangement of the priest!" Chen Yi did not object.

When he came, he planned to go back to Chang'an in the afternoon, but he felt it was too hard to come all the way. When he returned, it was the hottest time of the day. If it was too late and could not arrive in front of the gate of Guancheng, he would have to stay outside Chang'an City for a night. Therefore, he did not plan to go back immediately on the way. In addition, when he arrived at Zhongnan Mountain and saw Ning Qing, the little girl's affection made him even more reluctant to go back immediately. He also wanted to discuss the drug production with Sun Simiao, and wanted to ask Ning Qing about other things, so he decided to stay here for a few days and return to Chang'an when he had something to do.

Is Chang'an very hot? Where can I feel comfortable to live in Zhongnan Mountain?

Seeing that the master said this, Chen Yi agreed again, and Ning Qing immediately looked happy and went out to prepare lunch happily, and greeted Chen Ming and Chen Liang to rest in the guest room. She prepared tea for them.

Chen Ming and Chen Liang could see the relationship between the young master and Ning Qing. They knew that this little Taoist nun would definitely become the young master's concubine in the future. Although she was a concubine, it could be seen that the young master treated her very much. For those who were followers, the young master's women should respect them. Therefore, after following Ning Qing out, he would not take care of her and help Ning Qing do things.

After saying good things for a long time but they were ineffective, Ning Qing had to follow them and asked Chen Ming and Chen Liang to help her.

Not to mention how the three of them cook, they only talk about what Chen Yi and Sun Simiao talk about.

After sitting next to Sun Simiao, Chen Yi asked straight to the point: "Master Sun, I heard from Qing'er that you have been making some newly prepared medicines after you returned to Zhongnan Mountain. Can you tell me what medicines are? What are they used for?"

When they were in Chang'an, the two discussed a lot of drugs. At that time, Chen Yi knew that Sun Simiao would make some new drugs and develop some new prescriptions for treatment after returning to Zhongnan Mountain. He just heard from Ning Qing that Sun Simiao had already started his hand, so he couldn't wait to ask.

Chen Yi knew that the previous chapters of Sun Simiao's "Qianjin Prescription" that survived later generations mainly talked about drug production and prescriptions. He read it briefly, but he didn't read it well because it was too difficult to understand. But he knew that Sun Simiao was very proficient in pharmacology. He, a medical student who studied for seven years in later generations, did not compare his knowledge of traditional Chinese medicine with Sun Simiao at all. He felt that he had seen it in the ocean. When he traveled to the Tang Dynasty, he had to learn basic medicines and prescription knowledge. The only things that surprised Sun Simiao in pharmacy were those famous prescriptions that appeared after the Tang Dynasty and magical drugs such as penicillin. He felt that drugs like penicillin could not be made by him alone, or it was difficult to use it in clinical practice. Only with the help of Sun Simiao's hands can such magical drugs be made and used to treat patients.

Sun Simiao was not surprised at all that Chen Yi would ask this question, just as he was not surprised that Chen Yi would visit today, and said with a smile: "Zi Ying, I am just about to talk to you about the production of drugs, especially the penicillin you mentioned! During this period, I have collected some penicillin and placed it in a place to nourish it, but I don't know how to collect the 'toxins' they produce. I originally wanted to write a letter to ask you, you are here today, and it happened to be very good, so I told me how to collect and follow-up treatment. I heard you that day that this thing must be processed before it can be used effectively!"

"Yes!" Chen Yi nodded, "Penicillin can be obtained after cleaning and filtering with Penicillium, but it is very toxic and needs to be treated with anti-toxicity!"

Chen Yi then summarized the methods of inactivated toxins produced by Penicillium fungi based on the disinfection and sterilization methods in later generations. Sun Simiao was stunned!

"Ziying, what I said is quite reasonable, but I am worried that if the toxins produced by Penicillium are effective after being inactivated?" Judging from the observations over this period of time, Sun Simiao believed what Chen Yi said, because the things mixed with Penicillium are less easy to absorb than things without mixing, and can be preserved for a long time. To a certain extent, Penicillium inhibits the production of some substances that can cause sterilization, but Sun Simiao is worried that after the "inactivation" treatment as suggested by Chen Yisu, will the "toxins" obtained have any effect in treating diseases. If there is no effect, it will lose its meaning.

"Master Sun, I can guarantee that this will definitely be effective, but I dare not say how great the effect is," Chen Yi replied with a smile, and said again: "Master Sun, this newly made drug cannot be used on humans at first. You can use some sick livestock and animals for testing, such as falls, chopped cattle, sheep, horses, and finally inflamed livestock. Inject them with these refined and inactivated toxins to see the effect, and at the same time, you can also test the dose! We can only roughly estimate the specific content of toxins. When used on humans and livestock, the medicine must be applied according to height and weight. We have never known these before, and it has not been mentioned in medical books, but we can test them. Through the treatment observation of many cases, we can obtain results. With the data of these trials, this drug can be used for clinical treatment!"

"Well, it's reasonable!" Sun Simiao agreed with Chen Yi's statement, but frowned, "It's just that there are a lot of tests. It's hard to find injured livestock. Also, I don't have so much energy to try..."

Sun Simiao really hoped that Chen Yi would come to help him, but he was embarrassed to say it out loud! Chen Yi is the first to advocate this new drug. According to principles, Chen Yi should be in charge of this matter, but now it seems that he is a force promoter, not Chen Yi. However, based on his own understanding and intuition, he felt that the toxins produced by Penicillium can be used to treat diseases and are very effective. If he had not had such an understanding, he would not have spent a lot of energy on Chen Yi's one-sided words to do this. It is precisely because he felt that penicillin could bring earth-shaking changes to medicine that he was happy!

Chen Yi understood the meaning of Sun Simiao's words but he didn't have the energy to do this in detail. He immediately thought of Ning Qing and said to Sun Simiao: "Master Sun, I think Qing'er is competent for this. She is your beloved disciple and she has nothing to do. She can come to help you do this! A few days ago, Qing'er and I wrote medical books together. She also read these medical books well and knew a lot about many diseases. She also knew a lot about penicillin. I think letting him do this with you will definitely help you a lot!"

While staying alone with Ning Qing, Chen Yi talked to her a lot of medical theory, and said it while memorizing medical books. It can be said that she was a medical teacher for Ning Qing and taught her many modern medical knowledge in later generations. Chen Yi believed that with Ning Qing's intelligence, she would definitely be able to remember these things and slowly digest them and understand them.

He also privately talked to Ning Qing about the knowledge of penicillin and other antibiotics, especially penicillin, the easiest antibacterial drug, which was also discussed in detail. He talked about it for many days, including simple penicillin collection, refining, filtration, and inactivation energy technology. He even said some purification methods that require the help of modern instruments in later generations. He also believed that Ning Qing would never forget these.

Sun Simiao is about to make this item and is about to start experimenting with the effect. Chen Yi feels that if Ning Qing joins, there will definitely be unexpected gains!

Sun Simiao seemed to understand something from Chen Yi's words, and nodded with a smile: "Well, don't worry, I will ask Qing'er to help, haha! I believe that I will definitely be able to make a comeback!"

The two continued to talk about medicine, not only discussing penicillin, but also talking about the production of other drugs. Chen Yi also learned something from Sun Simiao's words that he had never expected. It turned out that Sun Simiao would use the herbs he collected to make some special drugs every year. From these narratives, Chen Yi further got to know Sun Simiao. The level of knowledge of medicine was beyond his surprise. He was so proficient. I really don't know how Sun Simiao figured out the medicinal properties of those herbs and figured out what changes would happen after the medicinal properties of several drugs were compared.

Well, it is said that ancient Taoists were all pharmacists, chemists, and physicists. Chen Yi didn’t believe it very much before. Now after knowing Sun Simiao, he believed it a little. The knowledge these people know is rich and difficult to imagine, and it is difficult to figure out how they know so much!

"Master Sun, what you know about medical theory and drug knowledge is really admirable. You must pass it on to future generations in the future to benefit more descendants!" Chen Yi sighed.

"You are right. The principles I understand will definitely be passed on to future generations. Ning Qing is more convincing than his two senior brothers. I will pass everything to her in the future!" Sun Simiao looked at Chen Yi and said meaningfully.

"That's great!" Chen Yi was very happy. He felt that a future pharmacist would grow up soon!

At this moment, Ning Qing came to tell that the food is ready and you can use lunch! (To be continued. If you like this work, you are welcome to come to Qidian to vote for recommendations, monthly votes, and your support is my greatest motivation.)
