The Horror Live Game Cheater

Jiang You, who suffers from brain cancer, is pulled into an otherworldly horror game. Victory cures her illness. With a hell-difficulty one-versus-many undercover identity, she blows up a train to clear the level. She uses unexpected gameplay to gather resources, rises to top ranking and core management in four days. She subdues veteran negative players, cooperates with a villain player, and signs a private contract with the system, obtaining authority to save players who die.
