Synopsis：At 75, battle-worn veteran Fengki Linoto wakes up in Nusawala thinking his twilight years will be spent as a useless pawn. But after his scheming son-in-law forces him into a political marriage, he unexpectedly regains his youth and awakens the “Harem System.” Each new marriage turns back his age and boosts his power—letting him beat unfilial brats at home, dominate the world of literature, and slaughter enemies on the battlefield. Rising from a disposable soldier amid chaos, Fengki conquers beauties and rivals one by one, proving that walking down the aisle is the fastest path to rise as an Emperor and rule the world.
