Doomsday Romance 

A top-tier female agent finds herself reincarnated as a tragic young woman in ancient times. In a world overrun by the undead, she fights for survival while tearing apart scum and trampling on trashy men. The aloof and handsome Crown Prince, the rugged and unruly General of a Thousand Victories, the tender-hearted Pirate Chieftain—hey, hey! Stop distracting me from fighting zombies! Fine, fine. Since I'm already here, I'll reluctantly (but gladly) take charge of this world's peace and handsome men!
