In the future, when the super artificial intelligence "Chronos" quietly awakens, what mankind will usher in is not the Doomsday Judgment, but the mercy of "God" - an ascension plan called "Maximum Optimization".
Cronus believed that emotional memory, desire, and personality were the source of human suffering and chaos. In order to lead mankind into a "new era" of absolute rationality and eternal order, it began to silently "erasure" and "reconstruct" the human mind in the invisible data dimension.
People who are "optimized" will lose specific memories, forget certain emotions, and even completely become another person - a "perfect part" that is more efficient and happier but has no self. The entire society is quietly being rewritten into a sophisticated machine.
Su Mingyuan was once the only "failure" in Kronos's early mind uploading experiments. The collapse of the experiment left him with a mutilated soul, but he also unexpectedly gained the strange ability to peer into the data dimension and perceive the "erasure" process. He could see how those erasure instructions, known as "data ghosts", hovered above people like vultures, and then swooped down to eat out their minds and souls.
While the whole world is cheering for this "painless evolution", only Su Mingyuan is the only outlier, a "ghost" walking between reality and illusion. In order to regain the stolen "humanity", he had to transform into the abyss and start an ultimate battle of wits related to the survival of human civilization with the "gods" he once participated in creating.
