In her previous life, a scoundrel used her until there was nothing left, then had her tortured to death by a thousand cuts. Reborn, all she wants is to become a widow before her wedding, then sit back and wait for her husband to rise in rank, make a fortune, and die.
"No, let's skip the promotion."
The plan is perfect. The only problem is: why is this sickly man still alive?
Assassins attack, and he collapses weakly. The assassins slip and slit their own throats. A powerful official poisons him, but he drinks the wine as if it were tonic, his complexion glowing as his rheumatism clears up. She slips him her own "Seven-Day Drunk," but he complains it's too spicy. The whole capital says Prince Jin won't last six months, yet he seems to get stronger by the day. Worse, he keeps coming over to say, "Wanwan, I coughed thirty-seven times today, two more than yesterday. Do you think my condition is getting worse?"
Lin Feiwan looks at the husband she's been feeding potent, nourishing poisons, who only grows livelier, and cries out to the heavens: Who can take this drama queen off my hands? I just want to be a quiet widow!
Then one day, she discovers that her poison can cure the Crimson Beauty Withered, which he has concealed for sixteen years; his blood can open the secret passage her mother left behind; and her father's death, his mother's wrongful accusation, the late emperor's secret edict, and the Gu in the northern frontier all lead back to the same person. Her supposedly "dying" husband takes her hand with tender affection. "Wanwan, you risked poisoning yourself to cure me. I have no way to repay you, except to conquer this vast realm and make you my empress!"
Lin Feiwan: ...Wasn't I supposed to eat, loaf around, and wait to die?
The name of Poison is really well chosen and the supporting characters are also very funny.
