The protagonist (a modern college student) accidentally travels through a VR game called "Time Rift". The time flow rate in the game is different from that in reality (1:30). The body in the real world falls into a coma and needs to complete tasks in a different world to wake up. In the low-magic steampunk world (magic + mechanical civilization), the social structure is similar to that of the Industrial Revolution, but the historical process is controlled by the "Time Administration", and the people at the bottom are oppressed.
