After Becoming a Substitute Bride, I Helped the Sickly Hostage Claim the Throne

Shen Weisu, a lowborn daughter of a concubine, is treated as a disposable pawn and forced to marry a hostage sent by an enemy state: Xiao Changye, a sickly prince held hostage. Everyone expects her to die a miserable death in the prince's residence, a prison in all but name. But no one knows that behind her seemingly frail appearance lies extraordinary cunning and a mastery of poison powerful enough to turn the world upside down. She quickly sees through her supposedly ailing husband's disguise and discovers that he is a hidden dragon with ambitions for all under heaven. Two top players, both cast aside by the world, hit it off and form the most dangerous alliance in a capital teeming with wolves and tigers.

Household rivalries? With barely a flick of her hand, she ruins the vicious matriarch and her scheming half-sisters. Harem power struggles? She plans her moves carefully, topples one prince after another, and raises her husband, a mere pawn, to the pinnacle of power. From a sacrificial bride forced into marriage to the empress who controls the realm, Shen Weisu proves through her cunning and ruthlessness that the greatest golden finger in this world is herself.
