Painting Bones as Husband

She, the most useless ink master in Si Tianjian, could not even drive away little ghosts by drawing talisman. He, the most ferocious regent of Dayan, was rumored to have suppressed his wife, and no one dared to approach him. Until she saw him having a bone-eroding curse and handed over half a steamed bun: "Eat something. When it hurts, bite it and it will make you feel better." She used a blood-painted talisman to calm his severe pain. The most expensive talisman in the capital was made by the poorest painter. But every time she draws a stroke, she will have one more gray hair and lose one year of her life. The crueler truth is: the curse on him was planted by her mother with her life; her life was "borrowed" by her mother. The life she renewed for him was a debt owed by her mother, and it was her life. When the century-old bone master's bloodline is fully awakened, will she choose to sacrifice everything to break the curse, or... Rewrite the entire rules with her own hands?
