Quick Transmigration: Villain Boss, You're Dangerously Charming

Xin Ai has lived for eons—so long she's stopped counting. When she's suddenly bound to the universe's most useless system (no cheats, no gifts, absolutely nothing!), this ancient supreme being decides to maintain her terrifying reputation the old-fashioned way: by eliminating everyone in her path. Can't touch the protagonist? Fine. Everyone else is fair game. Her poor system can only watch in horror as its host racks up a body count across countless worlds, all while inexplicably attracting the obsessive attention of dangerously powerful men. Pure 1v1 romance meets ruthless villainess energy.
