A strange apartment descends upon the world. Players earn gold coins through sleep to upgrade their dwellings and fend off the uncanny things outside their doors. An ordinary girl, Yu Yuan, unexpectedly unlocks the 'Ad Mama' system. She relies on watching ads to obtain absurd yet useful items, struggling to survive from the lowest rung. By chance, she wanders into 'Heroes Contend for the Deer' and meets Song Yu, the strongest combatant. The two team up to brave 'Rose Manor', expose imposters, and slay the Earl. The S-rank 'Peak Apartment' is forcibly activated. Yu Yuan, Song Yu, the maniacal villain Zhou Jiyou, and other top players across the server are conscripted— and a brutal new round of the survival game begins.
