Apocalypse Synthesis: I Craft Evolution Serums in the End Times

When the apocalypse turns the world into a mutant-infested hellscape, shut-in gamer Lin Feng awakens a biochemical synthesis system that transforms nightmares into power. Zombie glands plus alcohol? Immunity serum. Monster blood plus rare herbs? Strength enhancement. While survivors scramble for scraps, Lin Feng engineers evolution itself. His former landlord and influencer neighbor, once dismissive, now beg at his door—but in this new world, pretty faces and old money mean nothing. Only those who prove their worth earn a dose of his life-saving serums.
