Modern corporate slave Zhang Zhaozhao transmigrates to become Hua Ling'er, the second-wife of General Chi Yan. The original owner was infatuated with the general, and after drugging him she suffered the consequences and died suddenly, trading places for her soul. Facing a cold and guarded husband, household servants who view her with hostility, and her hypocritical and malicious cousin Bai Yuqi plotting against her at every turn, Hua Ling'er refuses to follow the cliches of inner courtyard fighting. Relying on modern makeup knowledge, she opens a commercial house called "Qiyi Pavilion" to build her career and make money. She outsmarts the white lotus, resolves crises such as assassinations and framing, and gradually develops mutual feelings with Chi Yan through constant sparring and tension. Hand in hand, they counter the Duke of Anguo's estate and Western Regions forces, making money and building a career while flirting with the iceberg general, intertwining sweet romance, business wars, and inner courtyard struggles.
