Father, who is both a heir and a descendant, is still biased; the bound system has gone berserk.

[Ancient Chinese Romance + System + Precognitive Dreams + Thrilling Read]
A crazy female lead vs. a crazy male lead
Ying Yufu's maternal grandfather, the Duke of Zhenguo, was her strongest backer.
Barring any unforeseen circumstances, her future is bright.
But one day, the Duke of Zhenguo's mansion fell from grace, and her father inherited both branches of the family line. He forced her mother to give her dowry of millions to her eldest aunt. Her fiancé said that the person he had always loved was his cousin from the eldest branch of the family, and the position of the principal wife should go to his cousin; she was only fit to be a concubine.
Just then, Ying Yufu was bound to a face-slapping system and had a precognitive dream.
In her dream, the Duke of Zhenguo's mansion was tragically wiped out, and she and her mother became stepping stones for the eldest son's family and her scumbag father.
After waking up from the dream, Ying Yufu was furious. Now that she knew her scumbag father and fiancé were despicable, then... she would be despicable too!
Reclaim the Flying Tiger Army that was stolen by her scumbag father, and use the miraculous medicine she obtained through the system to send it to the border to save her grandfather and her eldest uncle's family, ensuring their safe return.
He went mad, demanding the return of his mother's dowry, which had been squandered by the eldest son's family, and used the system's spatial storage to transfer it from the Marquis's mansion's treasury.
The second prince refused to return the money she had accumulated over the years, so she turned the tables and exposed his crimes of raising a private army and plotting a rebellion.
The mother took the three siblings and divorced in a grand and glorious manner.
The second prince and the empress, who had wanted her to be their concubine, finally panicked: "Fu'er, the person I truly love has always been you."
The dramatic crown prince sneered: Only I, the son of the original empress, am worthy to marry Fu'er. You, the son of the second empress, are not even qualified to be Fu'er's male concubine. Get out!
The scumbag father and his family knelt again outside the gates of the Duke of Zhenguo's mansion, begging their mother to turn back, but their mother had already eloped with the one she truly loved, infuriating their scumbag father.
