Doomsday Rebirth: The Ten Thousand Paths Heavenly Lock

Building power from the start + near-invincible protagonist + god-slaying + innate white-silk/black-silk sacred physique + no saintly do-gooder + multiple heroines + not a womanizer + spiritual qi revival + zombies + [the later parts are great] Qin Tian was mediocre before the apocalypse and still only a little better than average after it. Then he was reborn! Now a man with brains and a ‘chance,’ Qin Tian sets out on a desperate gamble: refining essence into blood, tempering his spirit with blood, and paying the price of being reduced to skin and bones! He seizes food from the jaws of danger, cultivates by extracting blood, forges a sacred physique, and shoulders the burden of humanity! He refuses manipulation, refuses to be shackled by grand causes, and refuses moral blackmail! The blurb can't do it justice. Read the story!
