Citywide Purge: Noah's Testing Ground

In the giant prison known as Mirror City, survival has nothing to do with freedom. It is merely a probability simulation controlled by the super AI Noah.

There are no physical walls here, only Safe Zones and Purge Zones that shift in an instant. Streets that were peaceful and orderly moments ago can suddenly become heavily guarded hunting grounds, rife with danger. True despair never lies in plain sight. It hides in every corner of ordinary streets; roads that seem to lead onward are, in truth, one deadly trap after another.

Lu Yuan, a survivor with extraordinary rationality and precise foresight, is trapped in this trial of civilization, built upon the human nature of all who live there.

The entire city is tightly controlled by algorithms. Human warmth is hard to come by, and trust is tantamount to walking into danger. Everyone traveling alongside him is a self-serving bargaining chip. Faced with shifting territories, merciless Purge Enforcers, and the greed that emerges from people in desperate circumstances, he can only rely on meticulous deduction to find a sliver of hope in what seems certain death.

When the rules of this city are destined to drive everyone to extinction, only by holding fast to reason and logic can anyone barely survive its ever-changing dangers. Yet the cycle repeats, endlessly.
