In Sanctum, luck isn't random; it’s engineered. The elite pay for probability enhancers, while the poor rot in the "Zero District," slaves to statistical irrelevance. Joseph Vance is a "Null." A data-analyst who crunches numbers for the underworld but refuses to gamble. He believes in cold, hard math, not the rigged games of the House. But when his sister, Elara, is seized by the "Debt Collectors" for "organ collateral" on their father's unpaid loans, Joseph is forced into the glitzy, neon-soaked arenas he despises. Out of options, he challenges a Sector Boss to a game of high-stakes probability. He loses. Badly. Beaten and thrown into the city's disposal chutes, Joseph lands in a graveyard of discarded tech. Broken and dying, his blood mixes with a prototype military chip rumored to be a myth: The Chaos Engine. [System Booting... Neural Interface Linked.] [Protocol: Entropy Exchange Active.] Joseph doesn’t get magic. He gets a processor capable of hacking the probability of the physical world—but the fuel source is his own biological decay. He can force a lock to open, a bullet to miss, or a card to turn, but every manipulation accelerates his cellular aging. To save his sister, Joseph must bankrupt the House. But in a game where he trades his youth for luck, the question isn’t if he’ll win—it’s if he’ll die of old age before he can cash out.

They tried to kill him on his birthday—just to take all his wealth. All this time, Logan thought he had nothing. But the truth was far more cruel: all the suffering he had endured was the doing of his own uncle, who treated him like trash within the family. On the night he was on the verge of death, a goddess appeared before him. Out of pity, she granted him a system that changed everything—the Multiplier Compensation System. From that moment on, Logan’s life changed. Wealth, power, everything began to grow without limit. He no longer cared about anyone… except for one thing—revenge. He built himself into an existence with infinite wealth, someone no longer controlled by anyone. “Now… you’re begging me?” “This is my ‘kindness’—to atone for all your sins.” And for those who once destroyed him, endless suffering would be the only fitting punishment.

Also, he is no longer Arnold Stone, the poor grocery owner who barely had a dime to his name. Now he is the host of a system worth trillions of dollars. King of the underworld and a rising Trillionaire!

In a world where wealth is no longer just power but an unrelenting curse, Leo Xu wakes up to an impossible system lodged in his very soul: a boundless fortune of ten trillion dollars, all locked behind a singular, maddening rule — every cent must be spent on women. Not property, not power, not freedom. Only affection. Only seduction. Only simping. From luxury resorts that shift their architecture based on a woman’s mood, to jet-powered earrings that vibrate to the rhythm of heartbeats, Leo’s journey spirals into a romantic fever dream twisted by capitalism, affection, and social chaos. But this isn’t just a harem fantasy. It’s an emotional arms race where status, sincerity, and strategy collide in a brutal economy of love. Each woman he encounters — from the ice-veined celebrity genius Amber Lin, to the enigmatic heartbreak of his past, Bella Zhao — holds power far beyond their looks. And Leo? He’s just trying to survive long enough to figure out if all this love is bought, or if he’s being sold.
