Neon Zero Contract

Stage 1: Mara Vey only needs to finish one last delivery and buy medicine for her brother. Instead, she opens a contraband crate and finds an upgrade core powerful enough to break the city's class system. The moment it activates, her health bar syncs with Knox Arden, the cold enforcer hunting her. Then the city announces purge mode. Every unregistered life will be erased. Stage 2: Trapped inside a sealed district, Mara and Knox must clear lethal missions before the system deletes them both. She can see the failure rate hidden beneath his perfect armor. He can shut down her core with one command, yet every command drags him closer to losing control. Forced to fight side by side, they uncover stolen memories, forbidden marks, and a power that wants them linked forever. Stage 3: Mara learns she was never an accident. She is the system's Zero Key, designed to unlock the city's heart. Knox carries the memory that could destroy its ruling order. To survive, they must reset the human upgrade code. Will they become the new gods of the city, or choose humanity and let the system erase them together?
