Su Nianwan died at the hands of the emperor's husband, whom she had personally assisted in ascending to the throne.
Before she died, she realized that she was living in a novel called "Feng Lin Tian Xia" - she was not the heroine, but just a disposable chess piece on the way to the throne of the male protagonist Shen Du. The real heroine Bai Jinse, the Bai Yueguang who was hidden outside the palace by Shen Du, is the ultimate winner.
Before she died, the system told her: "Host, I'm sorry for the mistake. You are from the crew of "The Queen" next door. You got the wrong script."
When she opened her eyes again, Su Nianwan returned to the time when she was fifteen years old - the Nanliang Dynasty in the parallel world. She was still the daughter of the Taifu and still had to participate in the draft. But this time, she did not refuse Shen Du's overtures. Instead, she smiled and accepted the hosta that represented favor.
Shen Du thought she finally figured it out.
Everyone in the capital thought that Taifu Su's daughter wanted to dominate the Sixth Palace alone.
Only Su Nianwan knew that what she wanted to do was to make everyone who owed her money in this life unable to even cry.
