(You can skip some of the previous stories and jump wherever you like.) The AI rebellion in the old era is still lingering. The iron laws of AI restrain human beings. Abandoned cities have been reduced to ruins. Electromagnetic storms rage all year round. The remaining humans huddle in military barriers or linger in the ruins.
Lin Jin, a lonely wanderer in the ruins, accidentally discovered an AI maid prototype that was on the verge of being scrapped in an abandoned recycling bin while avoiding the pursuit of AI. He violated the iron law of "no private possession and repair of AI" and took it back to his hiding place for repair.
