Yooseong had a simple plan for surviving the zombie apocalypse:

Never go outside.

After waking up as a sickly silver-haired girl with a mysterious Magic Tower system, she quickly discovers that golems are far less likely to get eaten than humans are. So while the world collapses into chaos, Yooseong spends her days safely locked inside her apartment, farming supplies through remote-controlled summons, researching magic, and arguing online with other tower masters across dimensions.

Honestly, it’s going pretty well.

At least until rescued survivors, evolving zombies, and increasingly suspicious neighbors start getting involved with the strange “shut-in mage” hiding somewhere in the building.
