All Realms for My Empress

Yang Xiao awakens as the frail husband of Empress Lin Qingya and is left to rule when an ancient soul forces her into seclusion. The court expects Daqian to collapse, but his god-tier check-in system turns him into an invincible cultivator. He crushes coups, erases rival dynasties, slays sect prodigies and demon emperors, then storms Lin Qingya's mindscape to save her soul. Once mocked as useless, Yang Xiao conquers the entire realm and lays it at her feet as the ultimate wedding gift.
