I Farm and Raise Kids With the Simp System

Reborn as a useless crown princess in ancient times, only to wake up in the middle of catching her husband cheating?

The scumbag crown prince points at her and curses, while her sweet-faced younger sister is two-faced and a master of fake charm. Shen Miaomiao, an interstellar war goddess with off-the-charts combat power, stares at her bootlicking System, which does nothing but shower people with praise, and is left speechless.
