In order to find the feeling of truly "alive", Lin Xia, a girl with extreme social anxiety, poor physical fitness but extremely high intelligence attribute of 19 points, was pulled by her friends into the closed beta test of the epoch-making neural direct-to-brain computer online game "Land of Fantasy". When connecting to the system, Lin Xia stubbornly refused the security protection and maximized the pain feedback to 100% on the verge of death. However, as the game progresses, she discovers that the world is eerily "real".
