Qin Shou, who had lived for five thousand years, was mistakenly diagnosed as mentally ill in this life and was imprisoned in Qingshan Mental Hospital. With his profound historical knowledge and amazing traditional Chinese medicine skills, he successively convinced psychologist Su Qingyue and nurse Wang Xiaoyan, and gradually gained the freedom of out-of-hospital surveillance. However, his sharp edge attracted the attention of Jiangcheng lord Zhao Tianhua. Faced with the temptation, Qin Shou chose to refuse and returned to the heavily guarded S-class quarantine area. The Zhao family immediately launched a revenge in multiple dimensions such as technology, capital, and the Internet. Qin Shou relied on his wisdom spanning five thousand years to launch a life-and-death showdown with Zhao Tianhua in the special battlefield of the mental hospital, and finally turned the tide.
