Xihe, a war god from the apocalypse, transmigrates into a period novel and becomes the notorious cannon-fodder ex-wife of a male supporting character. The original owner was fair-skinned and beautiful, and the darling of her family, but after being egged on by schemers, she tried to drown herself and confessed to the male lead's rival, turning her perfectly good life into a complete mess.
Now that Xihe has inherited everything from the original owner, she refuses to follow the plot. Everyone who bullied the original owner will pay for it.
And she even ends up with a handsome, elite soldier for a husband. After suffering so much in the apocalypse, she figures this life is worth it.
