In 2188, the federal city is divided into safe areas (elites), ordinary areas (middle class), and abandoned areas (bottom layers). The "Abyss Game" is a bridge connecting virtuality and reality. The neural threshold determines the upper limit of players. Hidden tasks can be exchanged for real resources. Lin Xia can break through the threshold limit due to her special neurological constitution. The goal is to take her sister out of the abandoned area and reveal the secret behind the game.
Purpose: "Resistance from the bottom" and "ethics of science and technology"
