In 2036, a zombie virus erupts across the globe, and all marine life mutates into man-eating monsters. In her previous life, Jiang Nian is betrayed by her husband, mother-in-law, and best friend, who seize her safe-room key card, break her fingers, and push her off a cruise ship to be devoured by sharks. As she lies on the brink of death, she is reborn on the very day she boards the ship and unexpectedly awakens a Safe Room System. Given a second chance at life, Jiang Nian abandons her former lovesick ways and maxes out her enemies' black cards to stockpile massive amounts of apocalypse supplies. She reinforces her safe room with blast-resistant doors and high-voltage electric fences, publicly exposes her enemies' hypocritical masks, and decisively cuts ties with them. She even resells an island destined to be swallowed by the zombie horde to her enemies, leaving them with neither their money nor the island.
