    In the duel between Zhu Youxiao and Sun Chengzong, the strategic directions of the east and north of the Ming Dynasty were roughly determined. For a while, Sun Chengzong really felt like he was strategizing and winning a victory thousands of miles away!

    At this time, Li Jinzhong came in and reported: "Master, Medical Officer Cheng is here!"

    For Cheng Yuyan, a special person, the eunuchs and maids in the palace respected her very much. This was not only because Cheng Yuyan was brought into the palace by Zhu Youxiao, but mainly because Cheng Yuyan was really good at treating diseases, and she was humble and kind to everyone.  She was so gentle and considerate that in just a few months, many eunuchs and maids in the palace were healed by her!

    In the cold storage place of the palace, many low-level eunuchs and maids are sick. Not to mention treating them, it is a great gift to meet a conscientious supervisor to let you rest for two days. And since Cheng Yuyan entered the palace, a pair of wonderful hands can save you.  A lot of people!

    Therefore, even without Zhu Youxiao's relationship, the eunuchs and maids in the palace also respected her. Even people like Li Jinzhong intentionally or unintentionally created opportunities for her to get close to Zhu Youxiao. Therefore, when reporting, there was no need to "ask for a meeting".  Just say "coming"!

    ??????????????????????????????????????????????Out

    Zhu Youxiao obviously didn't notice this difference. When he heard Cheng Yuyan coming, he smiled and said, "Let her in!"

    Sun Chengzong said knowingly: "Your Majesty, I have now resigned!"

    Zhu Youxiao knew that he would be wrong, so he waved his hand and said: "No, Yuyan is also an official of the Ming Dynasty. What are you avoiding when she comes to see me, the minister in charge of the Military Aircraft Department?"

    Sun Chengzong could only smile awkwardly, bowed and said: "I thought it was wrong, your majesty, please forgive me!"

    But Sun Chengzong secretly cursed in his heart: "You call this little girl Yuyan, and you still say that you are just a monarch and a minister. Isn't this deceiving yourself and others?"

    At this moment, Cheng Yuyan had already entered Nuan Pavilion. She was already petite, but she was wearing a fifth-grade official uniform. She looked like a puppet in a puppet show. She looked quite happy!

    When Zhu Youxiao met Cheng Yuyan, he couldn't help but smile on his face and said, "Why does Yuyan want to see me?"

    Cheng Yuyan saluted and said: "The first phase of experiments that your Majesty has entrusted to me has been completed!"

    Zhu Youxiao's heart skipped a beat when he heard this, and he quickly asked: "What's the result?"

    Cheng Yuyan said with a smile on her face: "I inoculated ten slaves with cowpox according to the method taught by your majesty. Five of them used the nasal blowing method, five used the piercing method, and ten of them were vaccinated after vaccination.  They all showed brief signs of fever, and then they were fine!¡±

    After hearing this, Zhu Youxiao said with a hint of disappointment on his brows: "This only shows that cowpox is effective for people, but whether it can completely prevent smallpox needs further confirmation!"

    Cheng Yuyan continued: "This matter has been tested before. Didn't His Majesty ask Dongchang and Shuntian Prefecture to pay attention to whether there are people with smallpox near the capital? A month ago, a child in a village in the south of the city had smallpox. Dongchang's  People told the minister, so the minister asked them to isolate the family and send the ten slaves to take care of the sick. As a result, four of the six members of the family died of the disease, leaving two children. Although their faces were numb, they were fine.  It¡¯s nothing serious, and none of the ten people were infected, so cowpox should be effective in preventing smallpox!¡±

    "Okay! If this method can be promoted, Yu Yan will live countless lives and become a Buddha in thousands of families!" Although Zhu Youxiao knew the result, the proof after the experiment still made him excited!

    "This method was taught by His Majesty, I don't dare to take credit!" Cheng Yuyan blushed when Zhu Youxiao said it, and she looked even more charming!

    Sun Chengzong, who was on the side, also understood the whole story at this time. His old heart couldn't help but beat violently. He couldn't help but interjected: "Your Majesty, what Medical Officer Cheng just said, does it mean that smallpox can be cured?"  ?¡±

    The excitement on Zhu Youxiao's face still lingered, and he said loudly: "Smallpox cannot be cured, but the cowpox vaccination method used by Yu Yan can prevent smallpox. As long as people are vaccinated with cowpox, they will not be infected with smallpox again."  !¡±

    Sun Chengzong was overjoyed and said: "I congratulate your majesty. In the Apocalypse, Mo Wenzhi's martial arts were suppressed. The fact that he restrained the disease of smallpox is enough to write a special note in the annals of history. Your majesty and Medical Officer Cheng will be famous forever!"

    Zhu Youxiao was also very happy. He mentioned this matter when he was bidding farewell to the old lama, but at that time he had not even written a word. He mentioned it in front of the old lama just to scare the old man, but now the prevention and treatment of cowpox and smallpox have been obtained.  Confirmed, then smallpox, a disease that comes from heaven, has really become a profit in Zhu Youxiao's hands.Got it!

    When Sun Chengzong praised Zhu Youxiao, Cheng Yuyan said again: "Your Majesty, the glass shop has sent me the microscope. I really saw the subtle things that your Majesty said!"

    Zhu Youxiao was stunned when he heard this. He did use the treasure of a microscope to trick Cheng Yuyan into the palace, and he did give the glass workshop the drawings for making the microscope, but he had already forgotten about it!

    And Zhu Youxiao doesn¡¯t think that a simple microscope can see anything extraordinary. After all, the advanced optical microscopes of later generations can only magnify 1,600 times. Human beings really entered the microscopic world only after the advent of the electron microscope!

    But from Cheng Yuyan's tone, Zhu Youxiao heard something unusual. It was obvious that what Cheng Yuyan saw through the microscope was not things like fly hairs or mosquito mouths!

    With curiosity, Zhu Youxiao asked: "What did you see?"

    Cheng Yuyan said with a touch of excitement on her face: "I saw the particles in the blood and the tiny bugs crawling in the dirt. This shows that your Majesty is right. Many diseases may be caused by these tiny bugs."  It¡¯s spread by bugs!¡±

    Zhu Youxiao couldn't help but cover his head and said: "What on earth did those people in the Glass House do to you?"

    This question was answered quickly, because Li Jinzhong led people to carry the microscope. Yes, that microscope was carried to Qianqing Palace by four eunuchs!

    Zhu Youxiao couldn¡¯t help but be stunned when he looked at the microscope, which had a brass-carved outer shell and an adjustment gear. It was one meter high and as big as a CRT TV!

    Zhu Youxiao remembered clearly that the drawing he gave to the glass shop was just a small microscope with three groups of lenses, but how did the glass shop come up with such a big thing?

    At this time, Cheng Yuyan had already sandwiched a piece of hair between two pieces of glass, placed it on the observation stage of the microscope, and adjusted the angle and viewing distance of the microscope with her own hands!

    Then he said to Zhu Youxiao: "Your Majesty, please take a look!"

    Zhu Youxiao moved closer to the eyepiece of the microscope and saw that the smooth black hair that was projected through the microscope not only showed the cuticle like scales, but also the damaged cuticle on the edge of the cuticle could be seen clearly!

    Although Zhu Youxiao didn't know much about the specific magnification of a microscope, he also knew that to magnify hair to this extent, it would require at least a magnification of more than 500 times. According to this magnification, Cheng Yuyan could see platelets and bacteria.  No wonder!

    At this time, Zhu Youxiao raised his eyes, looked at Cheng Yuyan and asked, "Yuyan, what are you going to do?"

    Cheng Yuyan pondered for a moment and said: "I plan to record everything I see, and then see if I can find out how those little bugs spread the disease!"

    Principal Zhu You said angrily: "If Yu Yan can accomplish this, her achievements will be no less than that of the Medical Sage and the Medicine King!"
