The Game I Made Became the Apocalypse for All Humanity

[Reborn + No romance + Game world + Apocalypse + Homesteading + Cute pets + Construction + Camper van] Ji Heng is reborn on the eve of the single-player game she created becoming an apocalypse for all of humanity. In her previous life, she thought it was just her own relaxing haven. A week later, she could only watch helplessly as eight billion people were dragged into a hell she had never designed: the Tide of Permafrost, mutating corpses, unnatural darkness... Humanity betrayed and slaughtered one another in despair. This time, she only wants to look after herself, using her foresight as the game's creator to stockpile resources and strengthen herself. Armed with the legendary longbow “The String of Turlunus” and four years of survival experience from her previous life, Ji Heng knows the real dangers go far beyond this. The unknown entity that tampered with her game's rules and keeps hastening the disasters seems to have accounted for her rebirth as well. Ji Heng: Whatever's plotting against me, get out of my game. (The heroine is powerful from start to finish, so don't worry about her getting outmaneuvered.)
