Biography

From deceptive surrender to coalition analyst

Xu's host abruptly retaliates against her bullies after possession, attracting official attention. Xu surrenders to the Homeland Defense Bureau but repeatedly gives false explanations of her keyword and skills, testing how much the officials know while positioning herself as an analyst. Her calculations make her valuable, yet she remains aware that raw speed can overwhelm even perfect prediction when the body cannot react quickly enough. (Chapters 459–470)

After Du Ge exposes the gathered candidates' real abilities, Xu gives up concealment and joins his coalition. She uses success-rate analysis to judge rivals and recognizes that Du Ge's presence radically improves an operation's odds. She helps plan the Bell Star operation and enters the final confrontation, though Lu Tingjie's speed prevents her from intervening when Du Ge is dragged toward the shield. (Chapters 487–508)

Appearance and personality

Xu appears as a timid fourteen-year-old girl but is calculating, skeptical, and capable of bluffing officials without a change in heart rate. She favors attacks whose odds can be measured. (Chapters 459–461)

Keyword and skills

Calculation gives Xu two analytical skills. Strategic Calculation renders relevant data numerically and helps her choose optimal actions, including evasion paths. Heavenly Strategy estimates each participant's chance of success in a defined event; its accuracy improves with the quantity and quality of available information. Neither skill makes her body infinitely fast, and missing or misleading information can degrade the forecast. (Chapters 470 and 487–489)
