The old man's name was Lü Yijian. He was a scholar of the Song Dynasty, serving as the Right Assistant Minister of the Secretariat and Grand Scholar of the Imperial Academy. He was also known as the Duke of Shen.,“He was in a coma. The imperial physician said it was blood stasis, with blood vessels in the brain clogged and stagnant. He had woken up for a while, but after regaining consciousness, he found himself blind. Terrified, he fainted again quickly. It is likely that this was caused by the blockage of blood vessels.”,Yan Shu looked at the frightened expression on his face and comforted him, saying: "Don't worry, it won't be. The doctor is a very good doctor, he said it wouldn't happen, so it won't. You will definitely get better, believe the doctor."。
