When mysterious monoliths crashed onto Earth, endless hordes of Calamity Beasts poured out, plunging humanity into a brutal war. In response, humanity awakened their last hope: the Transcenders. After watching the beasts brutally murder his parents, Kael is driven by a single purpose: absolute revenge. Years later, Kael awakens an ultra-rare class. The catch? His level is permanently capped. But he soon discovers a terrifying loophole—he can infinitely stack his stats by hacking his enemies' skills! Surviving hellish trials, Kael catches the eye of humanity’s very first Transcender and becomes his protégé. With limitless power at his fingertips, Kael begins his ruthless climb to the apex. The beasts took everything from him—now, they will pay in blood!
