Quick Transmigration: I’m the Female Lead’s Foil

(A supporting heroine’s quick transmigration; some worlds have a love interest, while others don’t.) There are always some women who are talented and beautiful, and who could have lived safe, happy lives. But to highlight the heroine’s beauty and kindness, these women have to become her foils: cannon fodder. They all meet bitter, humiliating ends. Shen Zhaozhao is one of those cannon-fodder characters. To change her own fate and those of the other cannon-fodder characters in the story, she is bound to a System and transmigrates through three thousand minor worlds to complete missions.
