Liu Zhaoyue, a concubine-born daughter of the Marquis's household, lives only seven words in the book: “Be tortured to death, then have her head displayed for all to see.”
Her stepmother frames her, her legitimate sister slaps her, and her father plans to make her take the blame. Everyone is waiting for her to die a wretched, lowly death, just like in the original story.
Too bad she's gone mad.
On a stormy night, she rushes barefoot into the Prince Regent's residence and tells the ruthless ruler, “That old injury in your left arm hurts from the hour of the Tiger until the hour of the Rabbit every day.” With guards holding blades to her throat, she smiles and offers him her life. “Your Highness, buy me.”
She knows where the lost imperial edict, missing for five years, is hidden. She knows the person the “mad princess” is waiting for is still alive. She knows every character's time of death and their weaknesses.
While everyone thinks she's a doomed pawn, she's already flipped the entire board.
This was supposed to be the tragic life of an abused heroine, but she turns it into a record of everyone losing their minds.
As for the Prince Regent, who once grabbed her by the throat and said, “I've caught you,” he later learns that he was never the one who caught her.
