Bankrupt heiress Su Wan is tricked into renting a room in an unfinished building. After falling asleep, she wakes up to find that she has traveled to the apocalypse — and brought the entire building with her! Zombies surrounding the building? She has an Absolute Safety Domain; any monster that comes near crashes into an invisible wall. Struggling to survive? She can trade bread for gold.

Just when she thinks the cheating scumbag and his mistress are her true enemies, she discovers that there is an even deeper reason behind her family’s downfall. As it turns out, Blue Star is not as simple as she once believed...
