She was a prisoner numbered "No. 13" In the Secret Academy. She was used as a "medicine" for refining the elixir of longevity. She witnessed the destruction of her family through endless torture: her father was framed, her mother drank poison, and her siblings died tragically.
Once reborn, she returned to the age of thirteen before the tragedy happened. The painful memory of her past life turned into a sharp blade. She tightened her grip on the copper buckle engraved with the crow shadow pattern and vowed to take revenge and protect her family.
The hypocritical temptations in the circle of noble ladies, the abnormal flow of money in the West Court Armory, the collusion between the mysterious organization and the imperial power... She worked step by step, tearing apart layers of conspiracies. Her family has become her strongest support: her mother uses medical skills to crack the drug network, her eldest sister collects blood and tear testimonies in the classroom, and her younger brother uses the academy to stir up trouble.
Along the way, she went from testing to forming an alliance with a mysterious ally, and gradually uncovered the secret of the royal family's forbidden technique of "using the daughter of a loyal minister to refine medicine." Facing the concubines, eunuchs and other masterminds behind the scenes, she fought fire with fire and set up a trap to fight back.
In the end, she not only overturned the conspiracy, but also promoted the development of female students and businessmen, and freed all the destinies that had been numbered and manipulated. "You want to use me to practice immortality?" She sneered, "I will make your souls fly away."
