I Have a Heaven-Defying Buff, Dare You Challenge Me?

No system. No golden finger. Just martial arts mastery and a god-tier buff that connects me to the Heavenly Dao itself. I thought conquering this post-apocalyptic world would be easy—until I realized Heaven was playing mind games with me. Fine. If the Dao wants to test me, I'll dive into the chaos myself. A millennium after the bio-crisis, humanity fights for survival against Inheritors, Zombies, and Demonic Beasts. With gene enhancements and mechs, we stand against titan-like monsters. But when Heaven itself becomes your opponent, who will win—man or fate?
