In the year 2088 AD, Ai Lin, a memory cleaner at the very bottom of the entire city, is being hunted like a mad dog by high-ranking hound Youliya. Youliya wants nothing else but to trade Ai Lin's head in exchange for an upper-class 'immortal ticket'. But when Ai Lin uses a broken offline device to forcibly smash open the firewall of the cloud divine temple, Youliya's faith completely collapses. Where is there any painless and blissful divine kingdom? Suspended in the clouds are tens of thousands of upper-class brains soaked in preservative fluid. The false gods ruling the entire city are crazily draining the dignitaries as living batteries!
