But fate had other plans. A mysterious black card, left behind by a dying stranger, transforms him overnight into a millionaire and unlocks a mission titled “Ashes of the Mega 7.” He must take down seven of the most powerful families secretly controlling the country’s economy each responsible for his past suffering, his parents’ mysterious death, and the corruption that rules the city. The first target? The Lewis family, his ex-wife’s bloodline.

Marcus West was about to swallow a handful of pills when someone started pounding on his door. Three years ago, he had everything. A restaurant he built from nothing. A wife who believed in him. A future. Now he's got $186,000 in medical debt, a dead wife, and a condemned hotel room in the Tenderloin. Then Jerome shows up bleeding, holding a USB drive and gasping: "They did it to you too. Here's proof." Turns out Marcus's life didn't fall apart by accident. His restaurant was sabotaged. His wife was a federal agent murdered for protecting him. His father was killed for knowing too much. The same people destroyed all of them. Now Marcus has something they didn't expect: the Karmic Debt System. A power that turns suffering into currency. Every nightmare, every loss, every moment of pain—it all has value now. And Marcus has been suffering for a very long time. They took everything from him. He is about to take it back and with interest. Can Marcus tear down the empire that destroyed everything he loved before the debt consumes him? Or will his quest for vengeance cost him what little humanity he has left?

Three hundred years ago... the sky split open. A wound in reality known as the World Scar connected Elyndra to countless unknown worlds, unleashing monsters, forgotten civilizations, and horrors beyond human understanding. Humanity barely survived. Those blessed with Genesis forged contracts with mythical beings, driving the invaders back and reclaiming their homeland. Then they uncovered an even darker truth. The World Scar would never stop expanding. The only way to save their world... Was to conquer the worlds beyond it. Kalexi Rowan dreamed of becoming one of the legendary Vessels who would lead humanity's advance into the Scar. Instead... He failed his Awakening. His dream ended before it ever began. Branded a failure, mocked by those around him, and destined to remain ordinary, Kalexi prepared to accept his fate. Until the World Scar swallowed him alive. Lost in a world where even the sky felt wrong, he encountered something that should never have existed. 《Welcome, Candidate of Ascension.》 《You have been chosen to participate in the oldest race in existence.》 《Failure... will result in death.》 Granted the Infinite Genesis Archive, Kalexi gains access to an endless library that records every being to have existed across countless realities. He cannot create life from imagination alone—but if he can understand it, and pay the price, he can call its Genesis into reality. Now thrust into a competition against Candidates from civilizations older than history itself, Kalexi must conquer one world after another, survive the judgment of powerful World Wills, and uncover the truth hidden at the heart of the World Scar. Every conquered world raises humanity's limits. Every Genesis carries the legacy of a forgotten existence. Every victory reveals an even greater frontier. And somewhere beyond the final world... Waits the secret that gave birth to them all. Countless worlds.

Reyan Sen died on the last day of school. Bullied for being powerless in a world that values strength, his life ended quietly—without meaning, without justice. But he woke up again. This time, as something no longer human. A strange system bound itself to him, turning him into an Undead being that must consume souls to survive. The world Reyan returns to is one shaped by an alien war. Humanity learned to use supernatural abilities to fight back, building military academies and power rankings where the strong are trained and the weak are discarded.
