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.

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