Sin System: Demonic Harem After Reincarnation

Have you ever considered what you would do if your tranquil world suddenly became post-apocalyptic, with mankind being persecuted by monstrous creatures and demonic beasts? Or humanity at the bottom of the food chain and being pushed to the brink of extinction?  ***  The crimson moon's appearance marked the beginning of everything; terrifying monsters and other beings, including vampires, werewolves, ghouls, and many more, have been present. These beings are referred to as the "supernaturals." The only people who can fight for humanity and prevent the extinction of humans are individuals who have extraordinary powers known as the "blessed." At a cost. Dave, a social outcast harassed for his lack of unique skills and being an orphan whose parents were killed by the supernatural, unexpectedly acquires access to the "system" with a unique lineage. Follow Dave as he rises to the top of a post-apocalyptic, dystopian society where the strong become predators and the weak become prey.

In ancient times, there were seven lockets. Each had magical powers. People don't know what happened to the lockets. The Mercks obtained one of these lockets and created a new gateway which allowed space travel. However, they were only able to use one of its numerous powers due to their lack of knowledge.

Still, they managed to send a few of their family members away. And that's where our story begins, with a young Merck stranded alone in an alien world, armed only with the locket left behind by his grandfather. Unknown to him, the gears of fate had already started turning, and the locket had started to wake.

He died a failure. He woke up a weapon. Ethan Cross had nothing: betrayed by the wife who took his fortune, disowned by his billionaire family, and publicly humiliated after a failed suicide attempt. At his absolute lowest, a cold, alien intelligence the Wealth Ascension System activates within him. Its offer is ruthless: complete impossible financial tasks for vast rewards, or suffer brutal neurological punishments for failure. With the System as his relentless engine, Ethan transforms from a broken man into "Mr. AK," a ghost of the financial world. He builds an empire in the shadows, amassing billions while systematically dismantling the lives of those who destroyed him. His ex-wife, Claire, watches in furious denial as the mysterious tycoon "Mr. AK" outmaneuvers her at every turn, never suspecting the rival ruining her ascent is the husband she left for dead. From a viral "Hobo Billionaire" stunt to a hostile takeover of his own family's empire, Ethan's revenge is calculated, cold, and spectacular. The final blow lands at Claire's own wedding, where a shocking public reveal exposes Mr. AK's true identity, destroying her new life and legacy in a single, devastating moment. But as one war ends, a greater one begins. The System's final message is clear: "Phase One Complete. Phase Two: Global Domination Initiated." Ethan must now decide if he is the master of this power, or merely its most valuable pawn. This is a story of bone-deep betrayal, astronomical wealth as a weapon, and a revenge so perfect it changes the world.
