"Dr. Dong, my name is Lu Li, also known as Lu Xunzhen. May I ask if you have developed a prescription to treat the plague?" Lu Li inquired.

Dong Feng sighed and said, "It's difficult. As Mr. Lu knows, once the plague breaks out, it spreads too fast, and I need to let the patients try it."

To put it bluntly, they were guinea pigs. Leifu took a few soldiers from the army and made them Dong Feng's guinea pigs.

More than a dozen people have died so far, and four different prescriptions have been tried, but none of them have been effective.

"Has Doctor Dong ever heard of any physicians?" Lu Li asked.

Dong Feng was taken aback. He naturally knew about the medical school, but it had ceased to exist since Emperor Wu of Han dismissed all other schools of thought and exclusively promoted Confucianism.

The medical traditions passed down through generations have disappeared without a trace.

"Leifu, take Doctor Dong and Zhang Zhongjing to Guigu."

"Tell Tong Yuan to pass on all the medical skills passed down by the medical family to the two of them!"

Upon hearing this, Dong Feng's pupils shrank instantly, and he excitedly grabbed Lu Li's arm, "Mr. Lu, are you telling the truth?"

The lineage of medical knowledge is actually in Guigu Valley?

“Yes, all the medical books passed down by the physicians are in my Guigu Valley. You and Zhang Zhongjing should go there quickly and see if you can develop a prescription,” Lu Li said in a deep voice.

"Okay, I'll go right away!"

Dong Feng was overjoyed and immediately followed Lai Fu to Guigu Valley.

Lu Li, on the other hand, left Bingzhou alone and headed towards Chang'an.

He knew that there were only three people who could come up with such a wicked idea: Li Ru, Jia Xu, and Cheng Yu!

Given Cao Cao's character, he would never do such a thing, especially with Guo Jia and Xun Yu involved, making it even more impossible.

Therefore, it must be those two treacherous strategists, Li Ru and Jia Xu!
