Overworked office drone Shen Qingzhi dies suddenly from working overtime and transmigrates into an ancient romance novel about a fight for the throne as a fake heiress who's doomed to be cannon fodder. From the start, she's shoved into a bridal sedan and sent to bring good luck to the God of Death, Prince Xuan, who is poisoned, disabled, and goes mad every full moon. Their nuptial wine is even laced with deadly poison.
In the original novel, she doesn't survive three chapters before Pei Xuanling shoots her through the heart.
On her first night in this world, she discovers that her natural scent can suppress the deadly poison inside Prince Xuan. The hand the God of Death has around her throat loosens.
From then on, Shen Qingzhi finds a new career path: becoming her mad boss's personal calming fragrance. Give her full meals, a good charcoal fire, and a hundred taels a month, and she'll keep her wealthy patron alive until he turns eighty.
The Marquis's Manor sends over a vicious servant? She cuts out his tongue and hangs him at the gate. Consort Shu sends poisoned bird's nest soup? The palace lantern just happens to fall on the real heiress. The Third Prince tries to steal her away in public? She knocks him down and breaks his tailbone. They pressure her to hand over military authority in the Golden Hall? She drops to her knees and cries until her own father has a seizure.
In his twenty-six years, Pei Xuanling has never seen anyone brazenly ask him for a monthly salary. Nor has he ever seen anyone cry while calculating the whole court's schemes down to the last detail.
“Your Highness, don't worry. I'm tough as nails. The King of Hell thinks I eat too much and doesn't want me.”
Later, the whole capital knows: the Princess Consort of Prince Xuan's Manor, who married him to bring him good luck, is soft and weepy. Touch her, and misfortune will strike you in return.
