The year is 2034. Without warning, mysterious Abyss Rifts ripped open across every corner of the globe. The first humans to step through the cracks discovered sprawling underground dungeons, treasures beyond imagination, and most revolutionary of all: the Heart of the Abyss, a primordial relic that can awaken supernatural abilities in ordinary humans, turning them into the powerful Awakened. Ten years later, abyss exploration has become the world’s most dangerous career. It is also its most profitable. For the Awakened who dare to brave the depths, a single run can turn a nobody into a millionaire overnight. For those who fail? Only a cold, endless grave in the dark. Lin Yuan is no elite Awakened. At eighteen, he’s a scrawny teen scavenger, scraping out a meager living picking through the refuse on the edges of the Abyss Rifts, just trying to survive another day. When a freak accident sends him plummeting into an unmarked, unmapped Abyss Rift, everyone who knows him writes him off for dead. A powerless, ordinary boy with no Awakened abilities? No one survives the uncharted depths. But the world has it wrong. In the blackest heart of the abyss, where no human has ever set foot, Lin Yuan does not perish. He awakens. Not as a run-of-the-mill Awakened, like the thousands who came before him. Instead, he binds to the [Abyss Sovereign] System: the one and only, never-before-seen hidden system in existence. What the rest of humanity fears as a death trap, a bottomless grave, is about to become something else entirely. For Lin Yuan, the abyss is no longer a prison. It is his birthright. His territory. His kingdom.
