In her past life, Su Yan was falsely accused of a pregnancy pulse by the cross-dressing divine physician Gan Jue, resulting in her being abandoned by the marquis mansion. She was 'rescued' by her lame childhood friend Chu Xun and worked to the bone all her life, only to find out this was a death trap set by the two of them for Gan Jue to cozy up to the marquis mansion! Returning to the day of pulse-taking through suspended silk threads, Su Yan secretly switched the threads, letting a seventy-year-old matron 'pulse out pregnancy'. Cleverly breaking the crisis and exposing the lie, she advanced by retreating to marry into the marquis mansion, laying out a big counterattack game. She watched coldly as her debauched husband indulged and self-destructed; then cleverly borrowed human greed to make Chu Xun and Gan Jue both reap what they sowed. Finally, holding a legitimate son and grasping a golden seal, she never looked up to anyone's breath again, ultimately becoming the true head mistress of this century-old marquis mansion!
