After dying and transmigrating to the modern world, Yao Meng discovers that her old world was actually part of a transmigration-and-rebirth novel, and that she was a pitiful sacrificial character.
In the story, during the reign of the empress, she was the chief female official. After a lifetime of struggle, she finally defeated the transmigrated male protagonist. So when the male protagonist died and was reborn as a child, the first thing he did was trick the Yao family into taking her in as his child bride. When he realized he couldn't win her over, he let his parents and sisters abuse and torment her until she fell gravely ill and died.
With his greatest enemy gone, the transmigrated male protagonist rose through the ranks by passing the imperial examinations, surrounded himself with women, and eventually joined forces with neighboring kingdoms to overthrow the empress's newly established dynasty. He became the emperor of the new dynasty.
But the empress was actually a goddess who had descended to the mortal world to undergo a trial. She and Yao Meng were as close as mother and daughter. After ascending to heaven once her trial was over, she learned the story of the male protagonist's rebirth. Furious, she restarted the timeline, brought Yao Meng back from another world, and gave her a pile of golden fingers.
So when Yao Meng returned to her original world, she found herself with five older brothers who had transmigrated from a matriarchal country and were all obsessed with spoiling their little sister, a pair of parents who favored daughters over sons, and countless treasures of gold and silver...
A little skit:
Transmigrated male protagonist: I finally got reborn. I'd better hurry up and bring home the rival who killed me in my last life. Either she becomes my first wife, or she disappears!
Male protagonist's parents: Son, we're poor, so we sold you to the Yao family to be their child bridegroom.
Transmigrated male protagonist: ...It doesn't matter. I can still make something of myself as a live-in son-in-law. I'll divorce her as soon as I pass the imperial exams!
Sister-obsessed brothers: Good grief, a man still wants to leave the house? Drag this man who doesn't follow a husband's rules back inside!
Yao Meng's parents, who favor daughters over sons: Once you join our family, you must follow the rules and the three obediences and four virtues. Stop having foolish thoughts. We'll give you a new name: Dai Nu. The right thing to do is hurry up and give our precious daughter a girl.
Yao Meng: Heh. I finally got reborn. I'd better hurry up and bring home the rival who killed me in my last life. Either he becomes my first husband, or he disappears. o(* ̄︶ ̄*)o
Transmigrated male protagonist: I must have been reborn the wrong way!!!
