The entire Su family was struck by disaster. Sickly orphan Su Jinluan took her place in a marriage and became a frail princess consort everyone could bully.
The world mocked her for coughing up blood and being weak, saying she would die soon. No one knew she was an expert in medicine, skilled at reading people, and harboring a ruthless scheme to avenge her family and topple the dynasty.
On their wedding night, a cold sword was pressed to her throat as the Regent, Xiao Moyan, demanded to know whose side she was on.
She coughed blood onto the blade and smiled, docile and foolish. No one knew that beneath that frail exterior lurked a long-hidden avenger.
She couldn't grieve deeply or give in to rage. All her cruelty was hidden beneath her smiles and laughter.
Step by step, she made careful plans, using her frailty as armor. By solving cases, she broke through deadly traps and turned a bloodthirsty living Hades into the sharpest blade in her quest for vengeance.
But she never imagined that the man who had held a sword to her was wearing a disguise too.
It turned out that inside the prince's manor, we were both undercover agents.
This book looks okay, at least it's not a running account.
