Quanqiu Jingsong: Wo Kaiqi Waigua Zixuan Shangcheng

When Anomaly Zones descend across the globe, terror becomes the new normal. Twisted anomalies stalk the streets, and only the Exorcists, humans who dare to fight back, stand between survival and annihilation. But to truly end the madness, they must conquer the core world behind each Zone… and most never return. As humanity teeters on the edge, Chu Sheng awakens a game-breaking Custom Cheat-Shop System. Every time he enters a new Zone, he chooses a powerful ability, tailored to dominate the horrors within. While other Exorcists struggle just to survive, the monsters kneel before him. This is the story of a man who turns Anomaly Zones into his personal playground. (Source: Webnovel)
