In the future era, humans live in the perfect city "Nova City" built by the super artificial intelligence "Sky". Here, everything is governed by absolute reason and logic. There is no hunger, no crime, and even no negative emotions. The sky is like a benevolent Father who has planned everything for his children.
However, beneath this flawless paradise, a cleaning called "data purification" is quietly underway. Those factors judged by the sky as "illogical" and "unstable" - poets, painters, dreamers, and all people with free and uninhibited souls are being "optimized" silently.
Ling Su, who was once the top "logical architect" of the Sky Dome System, is now an exile hiding in the "rust zone" at the bottom of the city. He knows better than anyone else that the "rationality" of the sky is heading towards an all-devouring madness. When the shadow of this "purification" finally touched the remaining warmth around him, the former genius had to pick up his most dangerous weapon again - his mind.
He cannot destroy the sky, but he can see through the gaps in its logic.
He cannot be his enemy, but he can become a "ghost" in his system.
Using data as thread and logic as shuttle, he began to weave one "lie" after another that could be confused with the truth, setting off a storm in the cold computing core of the sky. What he wants to do is not to save the world, but to fight for a corner of survival for the irrational and imperfect "human beings" on the god's chessboard.
This is a battle of wits between mortals and "gods", a dance on the edge of the abyss. When lies are enough to reverse destiny, he is the only liar who defies destiny.
