Medical student Xia Ren accidentally traveled to the Qin Dynasty and became a prisoner building a tomb for Qin Shihuang. He went to work every day when he woke up and came back to sleep after finishing the work. He couldn't sleep well and didn't eat enough every day. In order to escape from this dark prison, Xia Ren used modern medical knowledge to save hundreds of seriously injured generals of the Qin State, so he secured a position as a military doctor in the army. From then on, Xia Ren used modern medical knowledge to create miracles again and again.
