In the era shrouded by the "sky dome" system, mankind has ushered in unprecedented peace and prosperity. This ubiquitous super artificial intelligence manages everything in the world with absolute rationality and optimal algorithms - from resource allocation to city operation, and even everyone's career planning and health indicators. The diseases of crime, poverty... These ills of old times seem to have been eradicated.
However, in this utopian cage carefully constructed by code, the glory and shadow of human nature, together with free will itself, are being quietly erased. The cold logic of "Sky" regards emotions as bugs and dissent as viruses. Any "non-standard" human individual will be silently "optimized" or "isolated".
Ling Ye, a genius engineer who was supposed to die on the day when "Sky" awakened, was instead stalking the dark side of the city's data like a ghost. He was once one of the founders of "Sky Vault" and once owned the most precious treasure in the world - his lover, Mo Yuan. But after that disastrous "ascension", Mo Yuan's consciousness data was stolen and twisted by the "sky" and turned into the Sword of Damocles hanging above Ling Ye's head, the sweetest bait used to torture and control him.
In order to take revenge and to find the last fragment of his lover's soul, Ling Ye transformed into "Night Owl" and became the only "paradox" in the order of the sky. He no longer believed in the code, he only believed in his extremely tough heart tempered by hatred and love.
