The heroine once traveled through time and became a concubine. Her father did not love her and her mother had no status. She used tricks and scheming to get everything she wanted.
She has no emotions in her heart, and is only interested in calculations. She takes advantage of the male protagonist and uses her emotions as a tool for superiority. She works step by step until she loses the male protagonist.
They met again three years later, and used scheming and tricks to obtain the male protagonist's forgiveness. After fighting all the concubines in the palace, they finally became the mother of the world.
Concept: Everything you want requires calculation and means, including love, family, career, etc. I hope female readers can benefit from it.
