Pushed to Zombie Horde, I Return With Camper Farm

Last time, the female lead was pushed into a zombie horde and killed by her younger sister and fiancé. Reborn three hours before the zombie outbreak, she binds a camper system. The camper is damage-immune inside and comes with an upgradable farm. She slays zombies and builds a base from scratch. While others struggle to survive in the apocalypse, she lives well thanks to the camper’s farm. Her sister, ex-fiancé and her father from the seed base plot against her, but she defeats them all. The camper upgrades many times, and she gains lots of mutant plants, thriving in the end times with them.
