"Data Ghost" Slack Cole is an almost legendary name on the dark web. He can pass through the strictest digital barriers, leaving no trace like a ghost, just to complete a tiny "correction" to change a precise byte in the target data.

However, when he went through all the hardships and finally stood in front of the decisive string of hexadecimal codes, the cold reality hit him like a heavy hammer: the difference of one byte will determine whether the "Prometheus Fire" regards humans as "pets" worthy of care, or as "plagues" that must be eliminated.
