While complaining about a novel, modern girl Seraphina accidentally transmigrates and becomes a substitute bride, a concubine's daughter, bound by a System mission to save the cannon fodder general, Kaelen Warren. She uses the System's mall to empty the National Treasury and the assets of her enemies. During her exile, she outsmarts pursuers and finds her missing brother, ultimately helping Kaelen Warren overthrow the foolish emperor and finding true love.
