Catastrophe Zero

When the apocalypse came, Han Mengyun's genetic virus was activated, and he found that he had become an undead creature. Not only was he immortal, he could also control the living people he had bitten. What was even more terrifying was that his genes would slowly mutate. As biochemical zombies gradually infect the world and gradually get out of control, Day Zero will eventually come. Various mutants, and even artificially modified mutants, emerge in an endless stream... The world is in danger, civilization is collapsing, and survival or destruction is no longer something you can control!
