When he opened his eyes, the top modern toxicologist became a despised good-for-nothing concubine from another world.
Everyone laughed at her for being stupid and weak. Even her engaged fiancé broke off the engagement in public and married her gifted sister instead.
Until the overlord who ruled the northern territory, had a violent temper but was poisoned by a strange poison, stepped on the threshold of the city lord's palace.
He had scarlet eyes and tightened his grip on her slender wrist: "Cure me, you will be the wife of the Lord of the North."
But she carelessly twirled the silver needle and glanced sideways: "Take off your clothes first. To treat you, there are three conditions: first, I want the couple to break off the engagement and kneel and cry; second, find out the real culprit of the poison; third..."
She tapped his heart with her fingertips: "After you're cured, get away and don't rely on me."
Later, it was revealed that the real culprit was fatally related to his miserable childhood. She risked her life to detoxify him. On the night he was about to disappear, the northern border was frozen for thousands of miles. He went crazy and bloodbathed his enemies. He hugged her cold body and shouted hoarsely: "Liar... You have planted the antidote in my heart a long time ago."
