She died with hatred in her heart in her previous life and swore to take revenge.
She was given a new life, but transmigrated through time and space.
She decided to toy with this world as if it were in the palm of her hand.
She met the most important person in her previous life, but reality made her realize that the feelings had only ever been one-sided. So she would make sure that person met a terrible end.
She conquered this world, but her own affections dragged her into trouble.
One heroine and many male leads. The number of male leads will gradually increase.
Update it soon. It's well written. I hope there will be a male protagonist or other events to change the heroine's character.
