I recommend "Miracle Doctor of Huaxia" and "Special Forces Eliminated by Wolf Fang". Both books fit the plot described in the question. "The Miracle Doctor of Huaxia" was about Xiao Chu's dream of becoming a doctor of Chinese medicine since she was young. She put down her gun and helped people through Chinese medicine. "The Special Forces Eliminated by Wolf Fang" was about Chang Jun, who had been eliminated by Wolf Fang, but still managed to walk his own path as a Special Forces soldier. He also had Chinese medicine skills. I hope you like this fairy's recommendation. Muah ~😗
