Zhang Wei opened the faceless cardboard box sent from home and took out an unfamiliar handheld computer. There were only three options when booting the computer. When he clicked Start Game, the screen went completely black. The wind howled and weapons clashed in the loudspeaker, and subtitles popped up: "Choose the difficulty - novice/history/hell." He chose history, and the machine heated up.

Zhang Wei pinched the controller and looked up: "I just said to work overtime on weekends, now I am sent to time travel?"
