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.

The SYN virus turned men into flesh-craving monsters, causing the Earth to lose more than half of its population. Just when humanity gave up, fighters known as Reapers arose from the ruins, once infected but now immune. With their new strengths, these reapers could turn the tide. Alex Ray, just turned sixteen, was never meant to survive. Shot for defying a corrupt officer, his body is dumped in the Outer Regions—Earth’s deadliest horror land. However, God had other plans.

Otherwise, the virus will not only end humanity… but rewrite the very design of creation.

WARNING: MATURE CONTENT.. THIS BOOK IS RATED 18+... When Greg opened his eyes in a strange bed in a world not his own, he expected confusion, not a glowing screen that labeled him as a “Host.” But the system that bound itself to him wasn’t one of swords, spells, or cultivation it was something far more dangerous.

Will he use the system to grow stronger, or will he turn to something unrecognizable ? Caught up between survival, confusion, and evil deeds, Greg must walk between a line of man and monster in a world where temptation can kill mean weakness of man.

I was born a genius numbers, logic, strategy… all of it came easy. Everything around me felt painfully plain, predictable, and boring. Even the web novels I read were the same heroes driven by emotion, not reason. Pathetic. But that all changed the night my family was slaughtered by people who weren’t even from Earth. I watched my mother’s body hit the ground. I heard my sister cry my name one last time before she was beheaded And then they said it .. “Your bloodline has to be erased.” Then came the darkness. When I opened my eyes, a glowing figure stood before me a being that called itself a remnant. It offered me a deal: a system unlike any other. The Architect System. In exchange for freeing it one day, I would gain knowledge and the power to rebuild, reshape, and destroy. I don’t know what this new world is. I don’t care about fate, destiny, or prophecies .I sure as hell don't plan to be anyone's pawn. All I know is this I will find the ones who killed my family . Hell I would even rewrite destiny if I have to . And when I’m done with them, they’ll wish they were never born.
