Gender Swap: My Ghost-Marriage Husband and I Are from a Thousand Years Ago

[Gender transformation, boys' love, 1v1 + ghost marriage + raising Gu + ruthless protagonist + master dog trainer + planting love poison] (Miaojiang woman and silly male lead) Fang Yuan was a Gu cultivator from one of the thirty-six Miaojiang villages. But because his face was even prettier than a girl's, the defeated Tang army knocked him unconscious, dressed him in a red wedding gown, nailed him into a coffin, and married him off as the ghost bride of a dead man. A thousand years later, he opens his eyes again. Someone has dug up the coffin, and he climbs out alive, having gone from a man to a woman. The ghost-marriage contract has bound him to his dead husband for good, and his husband even comes looking for him later. He takes up the dying wish of the Feng family's illegitimate son, who was buried alive, and goes down the mountain under the name of the Feng family. A shocking revelation rocks the Feng family estate: the illegitimate son who died at a construction site was actually a girl. The Feng family, where no daughter had been born for generations, goes completely mad. Her several arrogant older brothers dote on their little sister, back from the dead, like she's the most precious thing in the world. But they don't know that their sweet, soft-spoken little sister is smiling as she plants Gu in them. Not one of them is getting away. You're all going to be my dogs.
