Reincarnated as the system's final player

He died ordinary. He woke up as the only person who could stop the end of the world. Nobody told him this until the assassins were already at the door. Park Sunho spent forty-one years watching history happen from a couch in Busan — Gates tearing open, hunters rising, the world rearranging itself around something new — and never once stepped into it. He died without ceremony and woke up screaming in a newborn's body in Aethoria, every memory of his wasted life intact and burning. This time he is done watching. Reborn as Kaelen Voss in a mid-tier hunter city, he grows up training daily with the girl next door, building something in the dark before the world knows he exists. At seven a system unlike anything in existence activates within him alone, naming him its only Player and the fourth soul an ancient intelligence has tried to arm against an extinction-level threat. The three before him did not survive to use it. His power is called Null Abyss. The Null bends the world away from him — a passive barrier growing more absolute with every level gained. The Abyss consumes what he defeats and stores it, bottomless and increasingly hungry, beginning to understand his intent before he voices it. Together they make him something the world's hunter associations cannot categorize, the Obsidian Court cannot capture, and the Void Sovereign — an entity pressing against the boundary of reality for three hundred years — cannot predict. He has fifteen to twenty years before the boundary breaks. The Court found his building in seventy-two hours. A rival born inside the Court is already on his way. And the system is watching every choice he makes. One Player. No ceiling. The clock is running.
