In 2130, the surface has become a radioactive wasteland. Humanity clings to life inside its last megacity, the Noah's Ark. The Titan's Heart, the energy core that keeps the city running, is failing at an irreversible rate and is expected to go dark within three months. When it does, a million residents will be exposed to deadly radiation and freezing temperatures, and the last spark of human civilization will be snuffed out. This countdown threat looms over every survivor like a sword of Damocles.
Long Si was once the chief maintenance engineer of the Titan's Heart, and the only person who knew how to repair its core. Yet when the core first began to fluctuate abnormally, she was accused of “sabotage” and “treason.” The evidence was conclusive, and she had no way to defend herself. Key parts were forcibly removed from her mechanical prosthetic, leaving it useless scrap metal. Stripped of every honor, she was exiled to the surface's most radioactive region, the “Land of Oblivion.” She faced the dual extremes of environmental and social oppression, a technological genius robbed of every chance to use her talents.
Civilization's collapse did not come from outside, but from within. On the seventh day of Long Si's struggle to survive on the surface, every survivor across the world, including those exiled there, was forcibly connected to a cold voice: “Apocalypse Survival System activated.”
