When a deadly extreme heat apocalypse hits and temperatures soar above 45°C, ordinary office worker Lilly accidentally binds an unlimited resource system. Her small apartment is instantly upgraded into a fully insulated, bulletproof fortress with independent power and endless supplies of food, water and daily necessities. She takes in her loyal best friend Nicole and Nicole’s medical student brother Anthony, living a comfortable life while the whole building suffers from extreme thirst and hunger.
A casual social media photo of cold air-conditioning and fruits triggers disaster. Her selfish ex-boy Jack stirs up all residents to besiege her flat. The crowd smashes doors, slanders her online and even fires guns, yet the reinforced metal wall stands unharmed. Lilly torments them psychologically by cooking fragrant hot pot and steak indoors while they collapse from heat exhaustion outside.
After seventy days of non-stop siege, Jack’s schemes backfire one after another. He gets infected from wounds and fails to seize supplies even with guns and forced break-ins. When the high temperature gradually eases and social order begins to recover, Lilly earns an S-level survival rating from the system. She is rewarded with an all-terrain vehicle with permanent access. Finally, she leaves the impregnable fortress with her two trusted companions and her dog, heading off to a new unknown, free future. Will the outside chaotic world bring new dangers or unexpected chances for them?
