Synopsis：Catherine wakes up in a new world as the infamous second princess: dead broke, despised by her four beastman husbands, and targeted by a scheming crown princess. Cornered on all sides, she unlocks a “Tycoon System” where every coin she spends returns tenfold. Armed with unlimited leverage and a modern mindset, she turns her finances—and her fate—around, rising from the most hated princess to the most untouchable woman in the empire.
