Three Kingdoms: Start by marrying Cai Yan, then vie for supremacy.

In the twilight of the Han dynasty, as warring factions tear the realm asunder and bandit hordes paint the countryside in blood, Lu Feng—scion of the stalwart Lu Kang—finds his fate irrevocably altered on the very morning of his betrothal to Cai Yan, the gifted daughter of the renowned scholar Cai Yong. What should have been a quiet celebration of union becomes the catalyst for a seismic shift in his destiny, as a mysterious sign-in system awakens within him. His first ritualistic claim bestows a prize far beyond mere gold or station—a transformative spark that ignites an ambition he never knew he possessed, compelling him to cast aside the gilded cage of aristocratic leisure and take the reins of an iron cavalry bound for the Yellow Turban front. With each subsequent sign-in along his arduous march, Lu Feng secures legendary armaments and attracts the allegiance of formidable martial talents, steadily forging a war machine from the ashes of chaos. Yet his path is not solely one of conquest; it is a steadfast pledge to shield his fledgling family from the machinations of a collapsing empire. Starting with his marriage to Cai Yan as his anchor, he navigates a landscape of shifting alliances and treachery, weaving together a network of renowned generals and loyal retainers. As he carves his territory from the fractured land, Lu Feng transforms from a reluctant heir into a determined warlord, driven by the singular resolve to protect his own and ascend to the pinnacle of power in an age where only the ruthless endure.
