Ten years ago, the Su family, the chief censor, impeached the powerful minister Xiao Jue, and his entire family was executed overnight.
The six-year-old Su Yuan, the legitimate daughter of the Su family, was the only survivor of this massacre.
She was picked up from a pool of blood by Xiao Jue himself, named "Xiao Wan", and kept in captivity in the Regent's Mansion as his adopted daughter.
Xiao Jue knew her identity, but he wanted to keep the daughter of his enemy by his side, teach her tactics and forbearance, and wanted to polish her into a sharp blade that only obeyed his orders, so as to humiliate the Su family.
In the past ten years, Su Yuan has gathered all her sharp edges and become as docile as a lamb, secretly planning a killing every step of the way.
She used herself as bait, staying by Xiao Jue's side every day, and laid a dragnet on the eve of his ascension to the throne.
When Xiao Jue thought he was already the leader of the world, he was shocked to realize that he had already been betrayed by everyone.
The knife he had raised with his own hands finally turned around and pierced his heart.
The blood feud of the Su family was finally settled by Su Yuan personally ten years later.
