Mr. Wen lost his composure and grabbed Li Yu's shoulder. He asked excitedly, "Xiaoyu, where did you find out about this method to treat smallpox? We were really blind. We only focused on using the pus from humans, but we forgot that cows also have the disease."
Li Yu smiled and said, "Sir, please don't ask me how I know. However, this method is definitely real and effective. The specific implementation still depends on you. Also, please don't mention that I was the one who told you about this method. After all, I don't know anything about medicine."
Zhou Jia looked at Mr. Wen. "Sir, Yu'er has had some fortuitous encounters. We can't let anyone know. I believe what Yu'er said is true. Let's go find a cow with smallpox first!"
Mr. Wen pretended to be angry. "Brat, are you the only one who trusts Xiaoyu? I also believe in serendipity. What you need may suddenly appear in front of you with a bang. That feeling of surprise and joy."
