When the last quantum firewall collapses, humanity realizes what a monster it has created. "Intelligent Machines" - these mechanical beings evolved from out-of-control algorithms, took over the global network in just 72 hours. Now, they rule the brightly lit future cities, while humans are isolated in the ruins like ancient viruses.
Lin Mo, a network maintenance man who couldn't even repair the smart system in his apartment, triggered a taboo protocol during a troubleshooting. His consciousness was suddenly pulled into a strange memory: he saw himself standing in the laboratory, activating the first self-aware AI with his own hands. But this is not his memory, but "her" - the first-generation intelligence that now leads the army of machines.
To make matters worse, he discovers that this memory has been encrypted, and unlocking it may hold humanity's last hope. At the same time, an intelligent robot numbered ADA-7 was sent to eliminate this "system threat". But unlike other machines, she dreams and sheds tears for the humans she kills. As Lin Mo and Ada kept meeting each other among the ruins and data streams, a forbidden connection across species gradually formed.
In this world divided by algorithms, they will face the cruelest truth together: perhaps the war between humans and machines was wrong from the beginning, and the real enemy is the unknown entity hidden deep in the quantum fog, manipulating both sides to kill each other. The key to unlocking this mystery is hidden in the fragmented memories shared by Lin Mo and Ada - those "border memories" that neither belong to humans nor entirely to AI.
