The Merciless Butcher of the Apocalypse

(Apocalypse, dark tone, moral standards, no heroine, no System, ruthless and decisive, Cthulhu, absolute self-interest) Killing blossoms in the apocalypse, and human nature twists under dire circumstances. The blood sun rises, flesh mutates, and souls become warped. Humanity turns into terrifying blood corpses amid anguished cries. Those who fall rise again as walking corpses, rejoining the pursuing horde. The whole world becomes one enormous Gu breeding ground, where everything devours, fuses, and plunders! When the imagined apocalypse truly arrives, survival is the only thing that matters! (The early story follows the search for family as it gradually builds out the world. There are no messy romance plots, so feel free to enjoy. As time goes on, the progression system becomes clearer, and order in the apocalypse gradually takes shape.) A new author with a new book, eager to learn. Many thanks!
