Professor Chen was a very rigorous person; since he said that Elder Liu's legs could be saved, it was absolutely true.
Liu Chengzhi could no longer care about appearances and quickly squatted down to ask, "Professor Chen, are you certain?"
"I'm about eighty percent sure," Professor Chen explained. "Elder Liu can now feel some swelling and a bit of heat in his legs, and he feels pain when I scratch them with my fingernail, which means that Elder Liu's legs have regained some sensory function. In terms of Western medicine, it means that the nervous system has been repaired. In the language of our traditional Chinese medicine, it means that the qi and blood are flowing again. As long as the blood vessels are unblocked, the following problems will be much easier to resolve. With targeted treatment, there is indeed a very good chance that Elder Liu will fully recover his health."
