On their wedding day the bridal sedan was carried to the front doors, but the Duke of Qin’s gates were shut tight.

They told her, ‘Come back tomorrow.’

—

After transmigrating to the past, poisons expert Han Yunxi finds herself on the verge of being married off to the country’s second most powerful man, the Duke of Qin. Her future life seems set–except her husband is an unfeeling ice block, her in-laws think she’s a eyesore, the empress dowager wants to use her for her own goals, and poison-related plots abound.

Alone, the intelligent (and sensible) Yunxi must carve her own space from the intricate web of court intrigue and the jianghu, relying on her words, wits, and wisdom to survive. Adapt when necessary, use force when required; to survive and thrive is the name of the game to a prosperous life.

No matter what, she’ll prove her right to live!
