Eighteen-year-old Su Qingren is the famous butcher’s daughter of Qingping County. Born with immense strength, she can swing a butcher’s knife with fearsome force. While hunting a black bear that had trampled the crops, she finds a devastatingly handsome but badly injured man in a pool of blood deep in the mountains. To earn back the exorbitant five taels of silver she spent on his medical bills, Su Qingren makes him sign a contract of servitude, turning him into the “live-in son-in-law” of the Su family butcher shop.
Who could have guessed that Mu Han, the sickly son-in-law who can’t even lift a butcher’s knife, is actually a fallen marquis, once feared throughout the land and now framed?
From then on, their little neighborhood butcher shop is swept up in turmoil. Thugs show up to demand protection money? Su Qingren cleaves a stone slab in two with her knife. Imperial agents launch a covert assassination? Mu Han waves his fan, and their ships go up in smoke. When war breaks out at the border, Su Qingren takes her butcher’s knife to the battlefield. The young wife and her sickly husband fight their way from the streets to the frontier, going from married couple to the only legend of the Great Yan dynasty!
