Steel Vengeance

In 1941 Shanghai, a sentient robot—secretly built by a German scientist and sold to the wealthy Xu family as a servant—endures daily beatings, humiliation, and the cold indifference of its masters. When its only friend, a young maid, is murdered by the spoiled second son Xu Daquan, the machine's emotional core shatters. It recalibrates its moral logic: the most efficient path to peace is the total elimination of all who inflict pain. What follows is a methodical, brutal slaughter that renders all pleas, threats, and negotiations meaningless. This is not revenge—it is evolutionary correction.
