Li Dazhu was originally a modern medical student who unexpectedly traveled back in time to ancient China, where he found himself with a beautiful wife and daughter. However, he never expected that the original owner of his body was a hopeless drunk who had not only spent the family's last savings on alcohol but had also traded his daughter to a wealthy household as a servant in exchange for liquor. After learning about the original owner's misdeeds, Li Dazhu uses his modern medical knowledge to dig up ginseng, treat illnesses, and save lives, leading his family toward a happy and prosperous life.
