The apocalypse strikes abruptly with raging zombies and falling meteors. Four girls from Dorm 502 at Shanhe University accidentally press the F key and board the mysterious Infinite Train, embarking on an apocalyptic survival journey with an unknown destination. Starting from their first dungeon, Zombie Night City, the four awaken special abilities one after another thanks to their extraordinarily high mental stats, forming an all-around golden squad: assassin, archer, support, and mobile RV. Braving life-or-death dungeons, stockpiling survival supplies, and building wasteland infrastructure along the way, they grow step by step from flustered college girls into the core of the wasteland's top server alliance, the Flower-Planting Clan. A lighthearted, hilarious journey of shared growth.
