She held her sister's final secret and the prophet of the future. She smiled at the scumbag husband's false promotion, and outwitted the forces who wanted to see the Changsun family's joke. At the same time, in the late-night game with the Ninth Five-Year Master who was getting more and more wrong, she gradually revealed the obsession and tenderness he had hidden for two lifetimes.
