Wear the reddest wedding dress and play the hardest chess.
Shen Qingci married the legendary violent and bloodthirsty regent of an enemy country on behalf of his eldest sister.
The whole capital is waiting for her death.
On their wedding night, she used a game of lost chess to make the tyrant change his face.
Tyrant: Who are you?
She smiled: Your Majesty, guess what?
Later, he pressed her against the wall and said in a low voice:
"I will admit defeat in this game of chess."
"But you can't win against me."
