Delta: We agreed you'd be a mouse, but you became a demon king general.

A former FPS prodigy transmigrates back to Season 4. In this world where Delta Force is a global phenomenon, many of the CS gameplay styles from his previous life are still untapped. Lin Chen, with his "possession strategy," "bridge blocking strategy," and "Old Bei bombing" tactics, dominates the internet, transforming from a universally ridiculed loser into a fearsome demon general that strikes terror into the hearts of professional players—"Who told you a mouse can't be a general?" From streamer competitions to professional leagues, from "mouse" to "demon general," every burst of Lin Chen's talent shatters everyone's perceptions. A female streamer mocks him for only picking up trash? He directly crashes his car into her seven times and captures her. When a reporter asks him why he pretends to be a mouse, Lin Chen laughs: "We agreed to be a mouse, but you forced me to be a demon king!" His catchphrases: "Command center, command center! Pay up!!!" "Go recognize your godfather, call him Ma, tonight we'll block the bridge with flowers!" "My armor! My dentures!" "Flowers! Liu Tao, it's Liu Tao!"
