Once married as a substitute, she became the happy wife of the sick and frail Lord of the Marquis of Yongchang.
Everyone laughed at her because she was from a humble background, an abandoned child of the Shen family, and could not survive more than three days.
But little did they know that she had the blood feud of her biological mother, possessed the lost secret technique of blending fragrances, could distinguish hundreds of poisons, and could even... Confuse people's hearts.
In the deep house, the old lady is inexplicably comatose, the Marquis is coughing up blood and is on the verge of death, and all the monsters and monsters have their own hidden agendas.
Above the court, the father and brother colluded with the prince, secretly mined forbidden minerals, refined evil medicine, and plotted against each other.
And her biological mother, the old maid of Yongchang Hou Mansion who died young, is actually the key to all mysteries.
"The key lies in the Xie family's bloodline."
When the dusty last words sounded, the secret message in the red gold hairpin reappeared, and she and the seemingly exhausted Marquis were forced to get into the same boat.
He needs her superb medical skills and incense skills to break the situation, and she needs his remaining power and trust to seek revenge and find his roots.
Therefore, the sickly prince wielded his sword in the court hall and forbeared his wife to hold incense in the inner house.
They join forces to tear apart the mask of tenderness and move forward step by step amidst the treacherous conspiracy.
From the mixed poison deep in the house, to the blood-colored mining pool outside Beiya Town;
From the evil pill furnace in the imperial concubine's palace to the Nine Netherworld Aperture left behind by the previous dynasty...
A shocking conspiracy that lasted for decades gradually surfaced.
And when the final black hand appeared and pointed its sword at the imperial power, the blood of the Xie family became the final sacrifice.
Can she light up the evil-destroying incense inspired by his heart's blood to wash away the evil spirits and bring clarity to the world?
He held her cold and trembling hand and made a promise in desperation:
"Mountains and rivers are an offer, and the rest of your life is a promise. In this situation, you and I will live and die together."
The idea: She uses incense as a blade, he uses illness as a trap, and they engage in a thrilling and strategic love together.
