Bandit Queen's Husband: Warlord of the Resistance

When Duan Yu transmigrates, he expects immortal cultivation or demon slaying—instead, he's kidnapped by a fearsome female bandit chief who declares him her future husband. Before he can process being married off to a warrior woman, the Japanese invade, and suddenly this reluctant groom finds himself commanding a mountain fortress of outlaws against an empire. Armed with modern knowledge and a band of fierce bandits who answer to his wife, Duan Yu discovers that changing history might start with surviving his wedding night. One transmigrator. One warlord bride. An entire war to rewrite.
