Shen Weiyan, the sick and frail daughter of the Shangshu Mansion who could be bullied by everyone, was plotted by her stepmother and was given a marriage to the cruel and murderous Prince Jing, just to pave the way for her stepsister. On the eve of her wedding, she was imprisoned in a cold courtyard, just waiting for a death edict. Who would have known that this idiot, whom everyone hates, is actually the only descendant of the hidden poisonous doctor. That night, Prince Jing came out of the snow. She cleverly set up a trap and handed him a marriage certificate: "Your Majesty, how about a deal?" From then on, the situation in the capital changed. Those who had bullied her, humiliated her, and harmed her were all silently ruined and died unexpectedly. The world finally knew that Shen Weiyan was not a lamb, but a poisonous scorpion from Jiuyou. Her revenge had just begun.
