When Lin Xue was planning to make Yu Niang a concubine, Lin Ran was discussing with Dr. Wu about the prevention of smallpox. Previously, she had said that she could be vaccinated against cowpox. No, as soon as he was free, Dr. Wu found the village chief and said that he wanted to go to the cattle pen to have a look.

Yun Qi also heard that cowpox could prevent smallpox, so he followed behind the two curiously.

There is only one cow in the whole village, which is kept in the cowshed at the end of the village. Lin Ran and Dr. Wu arrived at the place and asked people to bring the cow out.

Dr. Wu is a very experienced doctor, and he just never thought that cowpox could prevent smallpox. Now that I know it, I will naturally not let go of this opportunity to practice. Almost without Lin Ran saying anything, Dr. Wu had already taken action.

Seeing that Dr. Wu was in high spirits, Lin Ran was also happy to be his assistant. The master and apprentice quickly extracted the cowpox. But the question is, there will be no smallpox patients, who will be vaccinated with this cowpox?

Master and apprentice, you look at me, you look at you, you have made a mistake for a while. In the end, it was Lin Ran who opened his mouth and said, "Master, why don't you vaccinate me." ”

"How can this work, what if something happens?" Dr. Wu firmly disagreed. Lin Ran was the only apprentice he accepted, so he couldn't have an accident.

For this reason, he said directly to Lin Ran, "It's better to do this, this cowpox is planted on my body." Anyway, I'm already halfway into the ground, so it's not a big deal. ”

As soon as these words came out, not to mention that Lin Ran disagreed, Yun Qi also resolutely disagreed. In the end, he proposed a compromise and said, "Doctor Wu, if you don't do that, I'll help you find someone who is willing to try cowpox." ”

"How are you going to find it?" Doctor Wu looked at Yun Qi. He knew that with Yun Qi's martial arts, it would be easy to threaten a person. But he didn't want to use this method to get the subject of the experiment.

"Doctor Wu, don't worry, I will definitely find a willing person to experiment with you."

"You promise!"

"I promise!" Yun Qi nodded, turned his head and ordered his subordinates to find someone.

Yun Qi's subordinates were very efficient, and it didn't take long to find such a person. The other party is a middle-aged man from a poor family, with a seriously ill old mother and a child waiting to be fed.

In order to see a doctor for the old mother, the family spent all the money. Hearing that Yun Qi was looking for someone to test the drug, he volunteered to become an experiment. Just because Yun Qi promised to give him a sum of money, he also promised to ask a doctor to treat his old mother.

After Dr. Wu saw the person, he also asked it in person, and made sure that Yun Qi was not difficult for a strong man, so he started to inoculate the other party with cowpox.

It just so happened that Dr. Wu and the others wanted to stay in the village for a few more days, so the man also stayed in the village after being vaccinated for observation.

Fortunately, after the man was vaccinated, except for some fever at the beginning, there were no other adverse reactions later.

After another day, the man's fever also subsided, and Dr. Wu was relieved, and finally believed that Lin Ran's words that this cowpox could really inoculate people.

If it weren't for the fact that he was in a hurry to return to the capital, Dr. Wu would have taken the man with him and observed him at any time. He was worried that over time, the man would have problems.

After Lin Ran learned of Dr. Wu's worries, he smiled and said to him, "Master, you can find a trustworthy person to pay a return visit to the man on a regular basis. In this way, don't you know what happened to the man? ”

After thinking about it, Dr. Wu felt that what Lin Ran said made sense, and began to find out who would be more appropriate to help him do this.
