Humanity huddles in a walled city built on huge light sources to survive. In order to exchange medicine for his seriously ill sister, Chu Tianxing, a slum scavenger, had to go deep into the most dangerous old world ruins. In an accident, he swallowed the mysterious crystal core from a powerful dark descendant, thus awakening the special ability to control "ether" energy. This power gave him hope to break his fate, but it also involved him in the vortex of disputes between various forces within the city. Faced with the threat of monsters and the greed of human nature, Chu Tianxing must protect his only relative and struggle to find the truth behind the disaster in this eternal night.
