With the help of Lu Yanzheng and Wei Chengzong, Doctor Mo's preliminary research work went very smoothly.
Jiang Qinyu didn't know anything about medicine, but Doctor Mo wanted her to be involved throughout the process. So, after confirming that Shufan and Pan'er had really recovered, she changed her clothes and followed Doctor Mo.
"Isn't this too much of a hardship for Madam?" Doctor Mo's lips twitched when he saw Jiang Qinyu's attire, and his eyes glanced at Lu Yanzheng.
Lu Yanzheng just smiled helplessly, said nothing, and looked at Jiang Qinyu with doting eyes.
"Please don't say that, Elder Mo. Since I'm learning from you, it's perfect for me to disguise myself as a medicine apprentice. Just please don't think I'm too old for you." Jiang Qinyu smiled playfully.
Doctor Mo shook his head, "Madam doesn't look her age at all; this outfit actually adds to her charm."
Jiang Qinyu doesn't have the kind of face that easily makes her look anxious. In addition, now that she's dressed as a medicine boy, her clear and bright eyes make her look even more lively and cheerful.
Lu Yanzheng deeply agreed and patted Jiang Qinyu's hair, saying, "I still have things to take care of. You stay with Doctor Mo, and let Aping handle anything that comes up."
In the past few days, after confirming that he was not infected with smallpox, Qin Shen was also sent out by Lu Yanzheng to run errands, and was not by Jiang Qinyu's side.
Jiang Qinyu nodded, said nothing more, and watched Lu Yanzheng leave.
Doctor Mo coughed lightly and said, "Shall we go too?"
They don't need to go out today; Wei Chengzhong has already had everyone who has had smallpox treatment summoned to Jiang Qinyu's residence.
However, the house is not very big, with two courtyards. One side is where Jiang Qinyu's family lives, and the other side is used as a guest courtyard, where Doctor Mo and others currently live.
Those who arrive can only be led to the guest quarters first.
Doctor Mo brought an apprentice with him this time, making two in total, including Jiang Qinyu.
At the guest courtyard, Yunzhu and the others had already made preparations, setting up a tent in the open space of the courtyard and inviting everyone inside.
"Please forgive me, everyone," Doctor Mo said as he entered. "It's freezing cold. It's not that I didn't want to invite you in, but smallpox has been rampant lately, so we have to be careful."
His explanation instantly put the minds of those who had been anxious and unsure why they had been called there at all.
As long as you're not in trouble and you're not going to them, everything is negotiable.
After the small talk, Doctor Mo quickly got to the point.
"What? We won't get smallpox anymore?"
"No way? I...wait, it seems like it really is?"
"Thinking about it carefully, it seems that none of the people I know who raise cattle and have had cowpox have ever had smallpox..."
These people recruited from the surrounding villages were mostly from poor families, so it was perfectly normal for them to keep livestock at home. Some of them didn't even keep livestock for their own families, but for others.
Doctor Mo looked at Jiang Qinyu and then said, "Think about it carefully again and see if there are any exceptions?"
Those who were summoned all frowned and pondered, trying to recall if anyone they knew who had contracted cowpox had subsequently contracted smallpox.
After a while, everyone shook their heads and said one after another, "No."
Doctor Mo felt much relieved, and his smile grew even warmer. "That's right. There's something I need your help with next..."
Jiang Qinyu said she came to study, and she really did study; she didn't say a single word the entire time.
She silently memorized Doctor Mo's way of handling things and his questioning techniques, thinking that she might be able to use them in the future.
After Doctor Mo led Jiang Qinyu out of the tent and the two went inside, Doctor Mo excitedly clasped his hands together and said, "Madam is indeed a blessing to the people of our Great Yue!"
While it cannot be ruled out that there might be other places where people have both cowpox and smallpox, based on the information provided by Jiang Qinyu and the information from the people we just asked, it is very likely that a smallpox vaccine can be made.
"Dr. Mo, please stop praising me. I really just happened to see it recorded in a book." Jiang Qinyu quickly shook her head.
She dared not accept the credit; it was something that another world was proud of.
"That would require you to love reading and read a lot to achieve that," Doctor Mo said disapprovingly, then sighed, "It's just a pity that I don't know which genius wrote such a book!"
After sighing, Doctor Mo began to get back to work.
Jiang Qinyu immediately perked up; her work was about to begin.
The reason she agreed to participate in the whole process was so that she could "casually" mention useful information when Dr. Mo had questions, thus helping him to quickly develop the smallpox vaccine.
However, her worries seem a bit unnecessary.
Even at dinner time, Doctor Mo was still engrossed in writing and drawing.
Jiang Qinyu glanced at the sky and stepped forward, saying, "Old Mo, it's time for dinner. Shall we go eat first?"
Doctor Mo stared at his notebook, his brow furrowed slightly, and shook his head, saying, "I've already deduced everything you told me before. If everything is fine, this thing can definitely be made."
Jiang Qinyu looked at him strangely, waiting for him to continue.
"But once the product is made, how do we get it to everyone?" Doctor Mo pondered, his eyes lowered.
What he made was medicine, and medicine is absorbed by the digestive system. But if it is absorbed by the digestive system, it won't achieve the effect that Jiang Qinyu described, which would prevent her from contracting smallpox for life.
Upon hearing this, Jiang Qinyu suddenly realized what was going on.
Modern vaccines are injected into the bloodstream using a syringe, which is different from drinking them directly.
However, such a thing didn't exist in ancient times. She thought for a moment and said, "If we want to avoid going through the stomach and intestines, there's only one way left."
"What method?" Doctor Mo suddenly looked up at her, his eyes full of hope.
Jiang Qinyu said apologetically, "This is just my ideal idea. Mr. Mo, please listen and see if it works. If not, we'll think of another way."
"Oh dear, tell me quickly!" Doctor Mo urged.
Jiang Qinyu said, "Besides direct absorption by the digestive system, we can also deliver the medicine into the blood vessels, where it will circulate throughout the body. That way, we can achieve the desired effect."
"Let the medicine flow throughout the body with the blood..." Doctor Mo repeated her words, then fell into deep thought again.
Jiang Qinyu stood quietly to the side, without saying another word.
"But... how do we find each person's veins?" Doctor Mo looked up at Jiang Qinyu again.
Jiang Qinyu was about to cry. If she continued, she wouldn't believe that she could have learned all this knowledge from miscellaneous books.
But I can't not say it!
"Um... Mr. Mo, you can clearly see the veins on our arms and the backs of our hands... As for how to put the medicine in? With a needle? No... Use a hollow needle to inject it..."
As Jiang Qinyu uttered her seemingly thoughtful words, Doctor Mo's eyes grew brighter and brighter.
He looked at Jiang Qinyu as if she were a rare treasure. After Jiang Qinyu finished speaking, Doctor Mo suddenly said, "Girl, why don't you become my apprentice?"
Jiang Qinyu: "..."
