Jiang Jin, a modern user of spatial superpower, travels through time into a chaotic era as Princess Jinyang of a fallen nation, destined to be delivered to barbarian captors for amusement. Right at the start, she slays the escort soldiers, joins forces with the God of War Zhou Sui, and executes her treacherous sister and fiancé with her own hands. Braving the perilous Liang City, she seizes provisions and weapons, winning the loyalty of destitute generals and strategists. Amid the flames of war, she rallies refugees, trains troops, and builds infrastructure without relying on anyone. Armed with intellect and spatial reserves, she marches step by step through a shattered world, determined to reclaim the lost land and carve out a female sovereign's hegemony.
