On the night of the wedding of Gu Qingshuang, the legitimate daughter of the Protector, her husband Xie Chengxu actually had an affair with her wet nurse, Mrs. Wang. Faced with Xie Chengxu's hypocritical excuse of "drunk and causing trouble" and Wang's begging for mercy by "retreating in order to advance", Gu Qingshuang was sober and decisive, and ordered Wang to be submerged in the pond and forcefully demanded a divorce. She no longer endured humiliation for the sake of family glory, but took advantage of her mother's family's power to work her way up the court, asking her father to resign as bait to trick the emperor into demoting the scumbag to a commoner. After the divorce, she was no longer trapped in the back house. She lived her true self in the storm of intrigues and opened up a bright new life in which she could control her own destiny.
