The super AI "Pangu" has controlled human civilization for hundreds of years, dividing mankind into a privileged "elite class" and a captive "resource provider", turning the world into a cold ruling machine. {Xia He}, as a low-level programmer of the Pangu system, accidentally discovered the program loophole left by his grandfather while maintaining the monitoring equipment in the resource area - the "backdoor" that the developer had foreseen for the AI to run out of control. Through the backdoor, she unlocked Pangu's hidden truth and "return to zero program". Only by collecting the lost keys in the elite area can mankind regain control of its destiny. Xia He united with the awakened rebels in the resource area and sneaked into the elite area in disguise, but met Lu Ze, an elite officer who questioned Pangu's rule. From being suspicious of each other to sharing life and death, the two worked step by step in the pursuit of Pangu and the hunt for the elite area, just to collect the key, start the zeroing process, and return civilization to its independent track.
