In the apocalypse, supernatural horrors descend upon the world, trapping everyone inside their apartment rooms. Only by sleeping in bed can people earn coins, upgrade their rooms, and fight for survival. Reborn from her previous life, Yu Yuan gets ahead by snatching a rare mystery box that once belonged to a powerful figure. She unlocks an absurdly powerful advertising cheat that grants her all kinds of special items for watching ads. Using a coin-doubling item, she rapidly upgrades her room and unexpectedly gets transported to the apartment building Zhulu, where powerful players gather. In this desperate situation, she struggles to survive with various items, encounters the top powerhouse Song Yu, and joins forces with him to fight numerous villains. Meanwhile, she uncovers mysterious treasures hidden inside her mystery box and begins her rise to power in the perilous wasteland apartments.
