He was once the most feared assassin in the martial world—a blade that killed without hesitation, a shadow that left no survivors. But when Jin Mu-Kang regresses, he awakens a cultivation system unlike any other—one that grows only through good deeds. Save lives. Show mercy. Protect the weak. Every act of kindness makes him stronger… while every drop of blood threatens to erase him from existence. There’s just one problem—his past is drenched in sin. The system reveals a cruel truth: the karma he earns isn’t a reward, but a debt. Every life he saves is merely repaying the countless lives he once took. Fail to balance it, and he won’t just lose his power—he’ll vanish entirely. Now hunted by his former comrades, distrusted by righteous sects, and constantly tempted by the ruthless strength he once wielded, Mu-Kang is forced to walk a path he was never meant to follow.

Osric Thorne was the discarded heir of the Thorne shipping empire, a man who thought he had everything until his wife, Elowen Vane, and his best friend, Cuthbert, threw him off the Gilded Sovereign in the middle of a Category 5 storm. With his feet chained to an anchor and the scent of Elowen's expensive perfume lingering in the salt air, Osric was meant to be a forgotten feast for the scavengers of the abyss. Instead, his family’s "worthless" heirloom—the Abyssal Pearl—reacts to his dying rage. Fusing with his heart, the pearl awakens the [Leviathan Evolution System]. In the crushing, lightless depths of the Atlantic, Osric doesn't drown...he adapts. By consuming the apex predators of the sea, he gains their power: the obsidian armor of the great white, the bio-electric discharge of the deep-sea eel, and the terrifying sonar of the prehistoric leviathan. Now, a monster is rising from the depths. Osric Thorne isn't coming back just to reclaim his company; he’s coming back to dismantle the Vane legacy piece by piece and turn the surface world into his personal hunting ground. He was once a man of the boardrooms, but he has returned as the Warden-King of the Abyss. The elites of Oakhaven are about to learn a bitter truth: the ocean doesn't forgive, and neither does Osric Thorne.

In a world where your beast defines your bloodline, Leon is the academy’s punchline. While the elite flaunt obsidian dragons and celestial tigers, Leon is shackled to a "feeble" Xenomorph Queen—a low-rank insect that everyone assumes is good for nothing but digging dirt. But they are wrong. Dead wrong. Hidden beneath Leon’s calculated silence is the [Ancient Hive System], a relic of a lost era. It doesn’t just tame; it evolves. By feeding his Queen the marrow of prehistoric fossils and the genes of forgotten predators, Leon transforms a "paltry bug" into a biomechanical nightmare. Armed with the reinforced plating of a Triceratops and the lethal precision of an apex killer, his swarm is growing. While the "geniuses" mock his failing grades, Leon is building an empire in the shadows—a loyal, hive-minded legion that feels no pain, knows no fear, and answers only to him. The elite think they are the hunters. They haven't realized yet that in Leon’s world, they are nothing more than biological raw material for the next evolution. The Hive is hungry. And Leon has just given the order to feed.
